How does vaping affect your blood sugar?
The nicotine in vaping can cause a raise in blood glucose due to the effect of increased insulin resistance. Diabetics using insulin may need more insulin to control blood glucose effectively and Type 2 diabetics on tablet medication may need an increase in dosage to prevent the raise in HbA1c (average three-month glucose test).
Does vaping affect the benefits of fasting?
In terms of insulin resistance (a benefit of fasting is reduced insulin resistance) a recent study found that e-cigarette exposure or use was not associated with increased insulin resistance. So to summarise, the benefit to your blood sugar level and insulin resistance obtained by fasting, should not be affected by vaping.
Do e-cigarettes cause insulin resistance?
Therefore, when compared with non-users of e-cigarettes/conventional cigarettes, vapers showed no significant difference in HOMA-IR or GTT levels after controlling for age, sex, race, physical activity, alcohol use and BMI. To this effect, concluded the researchers, no association between vaping and insulin resistance can be observed.

Does vaping reduce insulin resistance?
The current research indicated that e-cigarettes use does not affect the development of insulin resistance, but could influence the level of glucose and pre-diabetic state development.
Does nicotine affect insulin?
Insulin helps blood sugar enter cells, but nicotine changes cells so they don't respond to insulin, which increases blood sugar levels. Chemicals in cigarettes harm cells in your body and cause inflammation. This also makes cells stop responding to insulin.
What happens if you vape while having diabetes?
If you have diabetes, smoking increases your risk of developing long-term complications of diabetes. This is especially true for heart disease. Many people switch to vaping as a less harmful alternative to cigarettes, but these products can also raise your blood sugar and increase your risk for diabetes.

Does nicotine raise insulin resistance?
Smoking is associated with insulin resistance in a dose-dependent manner. It directly increases the risk for insulin resistance, mainly via hormone activation, and may indirectly cause insulin resistance due to its effects on abdominal obesity. Nicotine may be the factor underlying these potential mechanisms.
Do Vapes have sugar?
No. Vape juice gets its sweetness and taste from flavorings and diluents.
Will vaping affect my blood test?
Smoking can also affect blood test results. If a person has been asked to fast before a blood test, they should avoid smoking. If you vape, it's fine to continue doing this during your fast.
Is it better to vape or smoke?
1: Vaping is less harmful than smoking, but it's still not safe. E-cigarettes heat nicotine (extracted from tobacco), flavorings and other chemicals to create an aerosol that you inhale. Regular tobacco cigarettes contain 7,000 chemicals, many of which are toxic.
Does vaping interfere with ketosis?
This is great news for all vapers, vaping won't knock them out of ketosis. Instead, it offers vapers the “sugar kick” they require, without consuming sugar and helps them maintain a healthy keto lifestyle. The ingredients of vape juice won't knock vapers out of ketosis.
Does vaping affect a1c?
Do e-cigarettes affect blood glucose levels? There has yet to be any strong clinical studies on the effect of e-cigarettes on blood sugar levels of people with diabetes. Research by Clair et al in 2011 showed that higher nicotine levels are associated with slightly increased HbA1c levels in people without diabetes.
Do Vapes have carbs?
There are no carbs in vape juice either, so there's nothing to worry about. You can always exhale the vapour, instead of taking it into your lungs, so all you get is the taste.
Can quitting smoking reverse diabetes?
New research reveals that quitting smoking type 2 diabetes mellitus patients. They may experience a transitory decrease in their glycaemic control that can continue up to three years. The National Institute for Health Research's School for Primary Care Research funded this study.
Does nicotine spike blood sugar?
Nicotine can make your blood sugar level go up or down. The chemical alters the way your body can use glucose, the sugar in your blood that fuels your cells. It could raise your odds of getting type 2 diabetes, and it can make your diabetes worse.
Does nicotine affect fasting?
While cigarettes with added sugars can, nicotine itself does not affect fasting.
How long after quitting smoking does insulin become more effective?
People with diabetes who quit have better control of their blood sugar. Studies have shown that insulin can start to become more effective at lowering blood sugar levels eight weeks after a smoker quits.
Can vaping increase your blood sugar?
A study published in March 2022 in The American Journal of Preventive Medicine conducted by researchers from Johns Hopkins shows that e-cigarette use may increase a personÕs risk for elevated blood glucose; in fact, those who vape have a 22% increased risk of developing prediabetes compared with those who do not.

Used appropriately, e-cigarettes may be a good transitional choice to help you quit smoking. Although the practice of using e-cigarettes as a stop-smoking tool is not an official guideline, preliminary studies suggest this approach may be effective.
Do e-cigarettes have nicotine?
Unlike their tobacco counterparts, e-cigarettes allow users to inhale nicotine and sometimes flavors without also inhaling the smoke, tar, and carbon monoxide found in traditional cigarettes. Because e-cigarettes are relatively new to the scene, we don’t yet have as much research about how they impact the body.
Does vaping cause diabetes?
What We Know About How Vaping Affects Diabetes Risk. Researchers already know that e-cigarettes are far from harmless. For instance, while their vapor may not contain some of the chemicals that traditional cigarette smoke does, they still can contain heavy metals and cancer-causing products, like acrolein, according to the CDC.
Does nicotine affect blood sugar?
The nicotine in e-cigarettes could also affect blood sugar. Research presented at a March 2011 meeting of the American Chemical Society suggested that nicotine caused hemoglobin A1C levels, the two- to three-month average of blood sugar levels, to rise by 34 percent. And those elevated A1C levels also indicate you may be at a higher risk ...
Can smoking cigarettes cause diabetes?
It’s well known that traditional cigarettes can increase the risk of type 2 diabetes and related complications, but researchers are still analyzing the potential relationship between e-cigarettes and the disease.
Should You Vape if You Have Diabetes?
Even though research is ongoing, most healthcare professionals feel we have enough evidence to take action. Here’s a summary of their advice:

Why do people use e-cigarettes?
The e-cigarette replaces the ritual of smoking gestures, the opportunity to reduce a bad smell, to reduce the cost of smoking, and the perception of general well-being might have been responsible for their switching and quitting .
What is in an e-cigarette?
The e-cigarette contains nicotine; propylene glycol (found in food and some medication used as a carry vehicle); glycerine, and food flavouring.
Does smoking cigarettes cause stroke?
Cigarette smoking predisposes the individual to several different clinical atherosclerotic syndromes, including stable angina, acute coronary syndrome (heart attack), sudden death, and stroke. Aorta and peripheral atherosclerosis (plaque in blood vessels causing narrowing) are also increased and lead to intermittent claudication (leg pain when walking) and abdominal aortic aneurysm 2.
Does smoking cigarettes raise blood pressure?
After smoking, nicotine raises blood pressure and pulse. It has a deleterious effect on insulin sensitivity in the fact that it decreases insulin sensitivity and can cause or aggravate diabetes. It has a negative effect on the endothelial (inner lining) of the blood vessels.

Electronic cigarette (e-cigarette) or vaping is increasing worldwide. Their use is highly controversial from a scientific , political, financial, and psychological perspective. Louise Johnson examines these controversies.
Does smoking cigarettes increase your risk of diabetes?
The research is clear on traditional cigarettes. Smoking can have a major impact on your diabetes risk. The Centre for Disease Control and Prevention (CDC) reported that tobacco smokers are 30-40% more likely to develop Type 2 diabetes. In addition, people with diabetes who smoke have an increased risk of complications.
What is the function of insulin in diabetes?
Insulin is responsible for enabling consumed sugars (glucose, fructose, lactose…) to enter the blood cells and to be transported throughout the body.
Does smoking raise blood sugar?
Smoking can make that task even more difficult. Smoking may make your body more resistant to insulin, which can lead to higher blood sugar levels.

Is nicotine bad for diabetes?
March 28, 2011 (Anaheim, Calif.) -- Nicotine appears to be the main culprit responsible for high blood sugar levels in smokers with diabetes, according to new research presented here at the annual meeting of the American Chemical Society.
Can you smoke e-cigarettes with diabetes?
E-cigs are an alternative to smoking, but what are the benefits and risks when you have diabetes? Smoking cigarettes puts people at a higher risk of developing health problems such as lung disease, cancer, high blood pressure, heart attack and stroke. Cigarettes contain nicotine and a mixture of other chemicals that can be harmful to your health. Electronic cigarettes, referred to as e-cigarettes or e-cigs, can be used to help people stop smoking. People with diabetes have a compromised immune system and are more likely to develop heart disease and stroke. This means they should quit smoking. Using e-cigs may be a helpful way to do this. While trying e-cigs may be helpful, one of the risks of e-cigs is nicotine. This is the substance also found in regular cigarettes which can be addictive because it may boost your memory, improve your mood and minimize your urge to eat. Nicotine is dangerous since it increases your blood pressure, increases your risk of artery blockage and stroke. An e-cig looks like a real one, but does not contain the additional poisons found in actual cigarettes. However, e-cigs do provide nicotine. Studies have shown tissues in the blood vessels can break down as a result of constant exposure to nicotine. This leads to the formation of deposits of fat, which narrow the blood vessels and may lead to heart disease. E-cigs have a battery and a cartridge to hold nicotine and other liquids, such as flavorings, water and glycerin. Some are rechargeable and others are disposable. Smoking e-cigs is referred to as vaping. Because they taste good with certain flavorings, people may “ Continue reading >>
Is smoking bad for you?
Even if you don’t know all the numbers, you likely know that smoking is bad for your health. It has a negative effect on every organ in your body. It raises your risk of potentially fatal diseases, such as heart disease, chronic obstructive pulmonary disease (COPD), and many types of cancer. As bad as smoking is for the average person, it’s even worse if you have diabetes. You already have a condition that affects many parts of your body. When you add smoking to the mix, it raises your risk of health complications even more. If you have diabetes, you have to work hard enough already to keep your blood sugar in check. Smoking can make that task even more difficult. Smoking may make your body more resistant to insulin, which can lead to higher blood sugar levels. Uncontrolled blood sugar can lead to serious complications from diabetes, including problems with your kidneys, heart, and blood vessels. Like diabetes, smoking also damages your cardiovascular system. This double-burden can be lethal. At least 68 percent of adults age 65 and older with diabetes die from heart disease, reports the American Heart Association. Another 16 percent die from stroke. If you have diabetes, you’re two to four times more likely to develop heart disease or have a stroke than people without the condition. Smoking directly affects your lungs and can lead to chronic bronchitis, emphysema, and other respiratory diseases. People with these diseases are at higher risk of developing lung infections, such as pneumonia. These infections can be especially dangerous when you have diabetes. You might get sicker than you otherwise would and have a harder time recovering. Being sick also raises blood su Continue reading >>
Does nicotine cause high blood sugar?
March 28, 2011 (Anaheim, Calif.) -- Nicotine appears to be the main culprit responsible for high blood sugar levels in smokers with diabetes, according to new research presented here at the annual meeting of the American Chemical Society. Those constantly high blood sugar levels, in turn, increase the risk of serious diabetes complications such as heart attack, stroke, kidney failure, and nerve damage. ''If you have diabetes and if you are a smoker, you should be concerned about this," says Xiao-Chuan Liu, PhD, a researcher at California State Polytechnic University in Pomona, who spoke about his findings at a news conference Sunday. In his laboratory study, he exposed human blood samples to nicotine. The nicotine raised the level of hemoglobin A1c, a measure of blood sugar control. The higher the nicotine dose, the more the A1c level rose. For years, doctors have known that smokers who have diabetes tend to have poorer blood sugar control than nonsmokers with diabetes. However, until Liu's study, he says, no one could say for sure which of the more than 4,000 chemicals in cigarette smoke was responsible. About 26 million people in the U.S. have diabetes, according to the American Diabetes Association, although 7 million of those are undiagnosed. Liu took red blood cells from people and treated them in the laboratory with glucose and nicotine at various concentrations. To measure the effects of the nicotine on the levels of blood sugar, he used the hemoglobin A1c blood test. This test measures the average blood sugar control for the previous three months or so. The higher the test results, the more uncontrolled the blood sugar is. Liu used doses of nicotine comparable to what would be found in the blood of smokers. The levels of nicotine he used in the lab would corresp Continue reading >>

Is Vaping Safe For Diabetics, Asthma Patients And Pregnant Women?
IS VAPING SAFE FOR DIABETICS, ASTHMA PATIENTS AND PREGNANT WOMEN? Although Vaping is totally safe for a healthy person, a pre-existing condition may call for restraint. Let's address the safety concerns for pregnant women, asthma patients and diabetics. Vaping juice contains two components that may cause an increase in ones blood sugar levels: Glycerine and sweeteners. But there is no concrete data that suggests that either of these would affect your blood sugar although some harbor that belief. There is a way to minimize the effects of glycerine on blood sugar though- Stick to unsweetened flavors like tobacco, and always vape a 60:40 ratio. We would recommend that you do a flavor testing at the Evolve Vapors office, and bring your blood sugar monitor along. Technically, Vapingis safe for Asthma patients, but we'd advise you to NOT Vape if having a serious respiratory condition. Take up Vaping only if you simply cant stop smoking as nothing could be worse than that. Technically speaking, Vaping is safe for pregnant women IF used with 0 mg nicotine, But we wouldn't recommend that you vape while youre pregnant Whatever you do, Dont Smoke, as smoking is more detrimental and abusive to your health than anything else!

Is vaping bad for you?
The effects of these substances on the human body are not investigated enough. While the overall health effect of vaping is low, there is still a debate on whether vaping can cause serious illnesses. Diabetes is a metabolic disorder which implies the lack of a hormone called insulin secreted by the gland called pancreas. Insulin is responsible for enabling consumed sugars (glucose, fructose, lactose…) to enter the blood cells and to be transported throughout the body. Without this hormone, carbohydrates deposit on the blood vessels and obstruct the blood vessels and blood flow. It is not easy to determine what exactly causes diabetes, but the most common ones are malnutrition, obesity, lack of physical activity, tobacco smoke, some viruses or genetic factors. E-cigarettes and gadgets contain water, flavorings, propylene glycol, vegetable glycerin and certain dose of nicotine (depending on the manufacture). Cigarettes are notorious containers of tar, arsenic, cadmium and benzene, all associated with potential cancer development. Zero nicotine vaping gadgets can be found on the market. Read more on the types of vaporizers and e-cigarettes. Most of them do contain nicotine – the most dangerous compound involved in vaping process. It is confirmed for it to increase the risk of narrowing the arteries and being addictive. A known fact among doctors is that smokers with diabetes usually have a lower blood sugar level control than non-smokers with diabetes.

Does smoking e-cigarettes affect blood sugar?
The nicotine in e-cigarettes could also affect blood sugar. Research presented at a March 2011 meeting of the American Chemical Society suggested that nicotine caused hemoglobin A1C levels , the two- to three-month average of blood sugar levels, to rise by 34 percent. And those elevated A1C levels also indicate you may be at a higher risk of complications from diabetes, including eye disease, heart disease, and kidney disease, says Janet Zappe, RN, CDE , clinical program manager of endocrinology, diabetes, and metabolism at The Ohio State University Wexner Medical Center in Columbus. We dont yet have all of the answers, and much of the research thats been done thus far is preliminary and doesnt meet the gold standard for research that is, being published in a peer-reviewed journal, and conducted with a randomized, placebo-controlled model. Researchers are still trying to answer many questions, such as: How do e-cigarettes affect your heart? The No. 1 cause of death for people with diabetes is cardiovascular, Zappe says. We already know that smoking increases the risk of mortality from cardiovascular disease, she notes but do e-cigarettes do the same, especially for people with type 2 diabetes? What are the long-term effects of e-cigarettes? Because e-cigarettes are relatively newer to the scene, we still need to understand exactly how they affect the bodys risk for disease. Even though research is ongoing, most healthcare professionals feel we have enough evidence to take action. Heres a summary of their advice: Avoid e-cigarettes if you dont already smoke. If you're currently a nonsmoker, theres no reason to start puffing e-cigarettes, given their potential complications with type 2 diabetes.

Can A Diabetic Smoke Marijuana?
Adults over the age of 21 would be allowed to carry up to an ounce of marijuana, and they would be allowed to cultivate for personal usage up to 25 square feet of cannabis plants. As of April 2009, 56% of Californians surveyed supported the legalization and taxation of pot. Let me be clear: I like this idea because I think it’s silly to have so much of our criminal justice system tied up with drug charges, and because I giggle at the absurdity of the fact that our state government is essentially saying, “Well, if you can’t beat ’em…” In other words, my reasons for liking this proposal, and for liking California, have nothing to do with the drug itself. In fact, pot itself is a big open question for me– namely: Can a diabetic smoke pot? I don’t mean “can” here as a verb of possibility or survivability. What I mean is– is it a good idea for a type 1 diabetic to smoke pot? How does marijuana affect blood sugar control and management, in terms of both behavior and biology? Lacking any personal experience in the matter, I first turn to the internet to answer these questions. The first thing I note: many other people are wondering the same thing. Rarely does Google pre-fill queries I have about diabetes, but this one Google is all over: “marijuana and diabetes,” “marijuana diabetes type 1,” “marijuana diabetes type 2,” “marijuana diabetes treatment,” and so on. The results of these queries are full of accounts from people with the personal experience I don’t have. There are apparently many message boards, either diabetes-focused or pot-focused, that have touched on the question of whether Continue reading >>
What happens when your glucose reserve is depleted?
However, when your glucose reserve is depleted, your body enters gluconeogenesis to maintain blood glucose levels and prevent hypoglycaemia (low levels). Think of this as a ‘back-up plan’ of sorts, for production of new glucose in the absence of carbohydrates from your diet. As you continue fasting, your body will begin to use fat ...
Can e-cigarettes cause inflammation?
This study, conducted in January 2021 found that repetitive use of e-cigarettes may disrupt the integrity of the gut barrier, increase the susceptibility of the gut lining to bacterial infections and trigger inflammation.
Does vaping help you lose weight?
In addition to this, nicotine is actually an appetite suppressor, which means vaping could actually help you to lose weight. It’s also worth noting that e-juice contains zero carbohydrates, so won’t affect those on a Ketogenic diet!
Does fasting help with diabetes?
BUT, several studies have found that fasting could not only reduce your blood sugar levels, but also improve blood sugar control by reducing insulin resistance. Which is a potentially HUGE benefit for those suffering from, or at risk of, type 2 diabetes.
Does vaping affect insulin?
In terms of insulin resistance (a benefit of fasting is reduced insulin resistance) a recent study found that e-cigarette exposure or use was not associated with increased insulin resistance. So to summarise, the benefit to your blood sugar level and insulin resistance obtained by fasting, should not be affected by vaping.
Does fasting lower blood pressure?
As you continue fasting, your body will begin to use fat or protein to maintain your blood glucose levels. Your metabolism will also slow to conserve energy, which means your body will burn less energy in a resting state. This also has the added benefit of lowering your blood pressure and heart rate.
Does smoking affect fasting blood sugar?
Yes and no. First the good news. I found this study, conducted to determine if smoking affected fasting blood sugar levels. I know the focus is on cigarette smoke, but the results should be comparable to vaping.
What is the prevailing glucose concentration?
The prevailing blood glucose concentration is representative of discrete metabolic processes which regulate the rate of appearance (Ra) for glucose versusthose which consume and regulate glucose disappearance (Rd). Glucose Ra represents glucose influx into the circulation primarily from the liver via glycogenolysis and gluconeogenesis as well as nutrient absorption from the gastrointestinal tract, with the relative contribution of each source determined by the nutritional state of the host and the experimental circumstances. As few metabolic studies are performed in the fed condition, contribution of glucose from gastrointestinal tract absorption to whole-body glucose Ra is typically considered be nominal after an overnight (or longer) fast. Further, despite the possibility that alcohol may increase intestinal glucose absorption, any alcohol-induced change in whole-body glucose Ra is primarily considered a manifestation of glucose output by the liver [25,26].
Does alcohol affect hepatic glycogen?
As noted above, alcohol administered acutely does not generally decrease whole-body glucose Ra but does markedly suppress gluconeogenesis. This metabolic scenario is consistent with alcohol acutely stimulating hepatic glycogenolysis under fed or short-term fasted conditions to defend against the development of hypoglycemia [9,11,45,46,47]. Many studies indicate that chronic alcohol intake decreases whole liver glycogen content [47,48,49] which occurs in both periportal and perivenous hepatocytes [50], and is consistent with the observed reduction in basal glycogen synthase activity. The decrease in hepatic glycogen appears to result from the ability of alcohol to inhibit the repletion of glycogen reserves which is directly related to the concomitant inhibition of gluconeogenesis [9,46,49].
Does alcohol affect insulin secretion?
The strong consensus from in vitroand ex vivomodels, although not entirely consistent, suggests that alcohol inhibits insulin secretion. Using the isolated perfused pancreas, alcohol did not alter basal insulin secretion but did impair glucose-stimulated insulin secretion (GSIS) in a dose-dependent manner [101]. Other studies reported that alcohol inhibits both early- and late-phase insulin secretion by the perfused rat pancreas [101,102]. Acute in vitrotreatment with alcohol or its metabolite, acetaldehyde, also dose-dependently reduces GSIS in isolated islets [103]. Moreover, a similar alcohol-induced reduction was observed when alcohol was administered in vivoand islet insulin secretion was assessed in vitro[104]. Likewise, incubation of INS-1 cells with 60 mM alcohol acutely reduced basal insulin secretion in a gamma-aminobutyric acid (GABA)-dependent manner [105]. In one of the most thorough in vitroexamination of the effect of alcohol on insulin secretion, alcohol had a dose-dependent inhibitory effect on basal and GSIS in INS-1 cells, dependent in part upon the duration of cell exposure to alcohol [106]. This inhibitory effect resulted from impaired muscarinic signaling and PKC activation, but was K-ATP channel-independent. Lastly, basal and GSIS are decreased in isolated islets from chronic alcohol-fed mice [100]. Thus, alcohol and its metabolites appear to have a consistent inhibitory effect on GSIS under in vitroconditions.
Does alcohol affect IMGU?
Skeletal muscle represents the largest body depot responsible for IMGU [130,131]. Therefore, an acute alcohol-induced decrease in IMGU by skeletal muscle per se has been inferred from experiments where whole-body insulin-stimulated glucose uptake is decreased during the glucose clamp (after correction for any residual endogenous HGP) [28,117,120]. Direct evidence for the suppression of muscle IMGU by acute alcohol was also reported in humans using the A-V difference method [52]. In further support, an alcohol-induced decrease in insulin-stimulated glucose disposal by skeletal muscle has been consistently detected in rats using radiolabeled 2-DG [12,14,117,118]. Interpretation of these seemingly consistent findings is complicated by a report showing that the magnitude of alcohol-induced insulin resistance is strain-dependent, with a more severe peripheral resistance observed in Sprague-Dawley rats compared to Long-Evans rats [14]. In contradistinction, as described above, the alcohol-induced hepatic insulin resistance is more prominent in Long-Evans vs. Sprague-Dawley rats. It has been suggested this strain difference may be related to differences in the generation of reactive oxygen species [28].
Does alcohol increase glucose tolerance?
Oral consumption of a moderate dose of alcohol at various times preceding an OGTT in humans has also been reported to improve glucose tolerance, which in this case may have resulted from an increase in pancreatic insulin secretion [26,93]. Similarly, chronic alcohol-fed mice have been reported to have improved glucose tolerance [94]. Some of this apparent discrepancy between these studies and the ones discussed in previous sections may be explained by a biphasic dose response (inverted U-shaped curve) to alcohol [95]. In this study an intravenous (IV) GTT was performed on rats maintained on different percentages of alcohol in drinking water. The data herein show that both relatively low (1%–2%) and high (7%) amounts of alcohol do not alter glucose disappearance, but that moderate doses of alcohol (3%) increase glucose tolerance and reduce the AUC for glucose. Large population-based studies have also reported that moderate alcohol intake over many years (>10 years) improves glucose tolerance and reduces the glucose-induced insulin secretion [96], implying increased insulin sensitivity.
Does alcohol affect glucose homeostasis?
Glucose homeostasis is critical for normal functioning of the central nervous system and cells which have an obligatory requirement for this metabolic substrate. Acute and chronic alterations in the prevailing glucose concentration (i.e., hypoglycemia and hyperglycemia) can adversely impact cellular and organ function. This review focuses on the etiology of ethanol (i.e., alcohol)-induced changes in glycemic control and insulin action at the molecular, cellular and tissue level, integrating the response of key glucoregulatory tissues including skeletal and cardiac muscle, adipose tissue and liver. As the underlying mechanisms of alcohol-induced changes are oftentimes dependent on the exposure time and intoxication level, these variables will be identified and accounted for when relevant. We will narrow our discussion to the effects of insulin on carbohydrate metabolism, but certainly acknowledge the potent metabolic effects this hormone has on both lipid and protein metabolism as well as the effect of alcohol on the secretion of other hormones [1]. Also, the literature pertaining to the ability of alcohol to alter insulin signaling pertaining to metabolic processes other than carbohydrate metabolism (e.g., hepatocyte growth and survival) will not be reviewed due to its extensive nature and readers are referred to other work on this topic [2]. Lastly, there is an equally extensive collection of literature on the effects of alcohol in individuals with type I and type II (±obesity) diabetes and it is not possible to include a systematic review of this topic. Throughout, where possible, we have highlighted limitations of various approaches which may complicate data interpretation and provide suggestions for future research opportunities in this area.
Does alcohol increase GSIS?
In contrast to its effect on insulin secretion in vitroand ex vivo, alcohol administered in vivohas been shown to enhance GSIS; in some instances this potentiated secretion is sufficient to increase the rate of glucose clearance from circulation (e.g., improve glucose tolerance) [26,107], but in others glucose tolerance remains impaired [99,111]. This priming effect develops within several hours [108] and occurs at relatively low alcohol concentrations (10 mM) [85]. Moreover, the ability of alcohol to enhance insulin secretion in humans was maintained in response to repetitive glucose challenges given over a 2 h period [93].
