    Circulation Problems Leading To Lower Extremity Infections Ulcers And Amputations

    The strain that both smoking and diabetes places on blood vessels increases the risk for slow wound healing and ulcers that affect the arms and legs and especially the feet.

    Blood vessels get smaller as they spread to the extremities, so the damage caused by diabetes and smoking is seen in these areas first.

    Decreased blood flow resulting from smoking and diabetes interferes with wound healing. In some cases, the infections in people’s limbs can become so severe that amputations are required.

    Effect Of Cigarette Smoking On The Blood Glucose Level In Normals And Diabetics

    Abstract The effect of cigarette smoking on glycemia was investigated in 26 diabetic patients and 24 normal controls, all smokers. Using the method with ortho-toluidine à jeun, blood glucose levels were determined before smoking and 15, 30 and 60 minutes after the smoking of two cigarettes. Both groups showed an increase of glycemia following smoking, more marked, however, in the group of diabetics. In 16 cases the experience was repeated once more, and an even higher increase of the blood glucose values was recorded as a result of the new nicotine charge. Conversely, no glycemia rise was noted after smoking nicotine-free cigarettes nor after smoking tobacco cigarettes but without inhaling the smoke. The increase of glycemia after smoking is assumed to be due to the mobilization of catecholamines and the stimulation of STH and cortisol production. This reaction seems to be more marked in diabetics than in metabolically normal subjects.Continue reading >>

    Finding May Explain Higher Risk Of Diabetes Complications In Smokers Study Says

    Serena Gordon

    SUNDAY, March 27, 2011 — Smoking is damaging to everyone’s health, but the nicotine in cigarettes may be even more deadly for people who have diabetes.

    In lab experiments, researchers discovered that nicotine raised blood sugar levels, and the more nicotine that was present, the higher the blood sugar levels were. Higher blood sugar levels are linked to an increased risk of complications from diabetes, such as eye and kidney disease.

    “Smoking is really harmful for diabetics. It’s even more harmful to them than to a non-diabetic,” said study author Xiao-Chuan Liu, an associate professor in the department of chemistry at California State Polytechnic University in Pomona. “This study should encourage diabetics to quit smoking completely, and to realize that it’s the nicotine that’s raising .”

    For that reason, it’s also important to limit the use of nicotine replacement products, such as nicotine patches, Liu said.

    “If you’re using them for a short period of time to quit smoking, that’s OK. But, if you still have this addiction to nicotine and are using this product long-term, it will do harm. Don’t use electronic cigarettes or nicotine gum for a long time. You need to stop nicotine intake,” he advised.

    Liu is scheduled to present his findings Sunday at an American Chemical Society meeting in Anaheim, Calif.

    Experts note that research presented at meetings is considered preliminary until it is published in a peer-reviewed journal.

    What Are The Lab Tests Which Might Be Affected By Biotin Supplementation

    How to Raise Blood Sugar Fast: With and Without Food

    There are many blood tests which can be affected by excessive biotin levels in your bloodstream. Some of these tests include vitamin D tests, any tests which measure the thyroid hormones in your body as well as tests which look at the FSH and LH hormones.

    Troponin is another type of test commonly used to diagnose heart attacks and other problems related to the cardiovascular system. If you’re planning to do such blood tests in the future, make sure you put your biotin supplementation on hold to ensure you get accurate results.

    How Does Smoking Increase My Heart Disease Risk When I Have Diabetes

    Smoking and diabetes both increase the risk of heart disease in similar ways. This means that when combined they greatly increase your chance of developing a heart-related condition such as a heart attack or stroke.  

    High levels of glucose in your blood and smoking both damage the walls of your arteries in a way that means fatty deposits can build up much easier. This is known as atherosclerosis. As atherosclerosis occurs, your blood vessels narrow and therefore blood flows through less easily.

    When this happens to your coronary arteries you can have a heart attack or angina. When this happens to the arteries that take blood to your brain, you can have a stroke.

    Diabetics Who Quit Smoking May Have Trouble Controlling Blood Sugar

    5 Min Read

    – Although smoking increases the risk of diabetes and quitting has numerous health benefits, diabetics who quit may have temporary difficulty controlling their symptoms, a British study finds.

    Researchers reviewed medical records for 10,692 adult smokers with diabetes in the UK and found that smoking cessation led to an uptick in blood sugar levels that lasted three years and was not caused by weight gain.

    Worldwide, nearly one in 10 adults had diabetes in 2014, and the disease will be the seventh leading cause of death by 2030, according to the World Health Organization.

    Most of these people have type 2 diabetes, which is associated with obesity and aging and happens when the body can’t properly use or make enough of the hormone insulin to convert blood sugar into energy. Left untreated, diabetes can lead to nerve damage, amputations, blindness, heart disease and strokes.

    Lycett and colleagues examined the impact of smoking cessation on diabetes symptoms by testing hemoglobin A1c, a protein in red blood cells that gets coated with sugar over time, making it a gauge of average blood sugar levels for the past two or three months. Diabetics have A1c levels of at least 6.5 percent.

    The study included more men than women, and most participants were white. At the start of the observation period in 2005, participants were 62 years old on average and had been living with diabetes for about six years. Many were taking at least one medication to lower blood sugar.

    Study Links Quitting Smoking With Deterioration In Diabetes Control

    Coventry University
    Sufferers of type 2 diabetes mellitus who quit smoking are likely to see a temporary deterioration in their glycaemic control which could last up to three years, according to new research.

    Sufferers of type 2 diabetes mellitus who quit smoking are likely to see a temporary deterioration in their glycaemic control which could last up to three years, according to new research published today in The Lancet Diabetes & Endocrinology.

    The research team1, led by Dr Deborah Lycett of Coventry University and funded by the National Institute for Health Research’s School for Primary Care Research, examined the primary care records of 10,692 adult smokers with T2DM over six years to investigate whether or not quitting was associated with altered diabetes control.

    The study found that in the 3,131 people who quit and remained abstinent for at least one year, HbA1c — which is an average measurement indicating how well the body is controlling blood glucose levels2 — increased by 2.3mmol/mol before decreasing gradually as abstinence continued.

    In the same period, 5,831 continual smokers — who did not change their smoking status during the study — experienced a more gradual increase in HbA1c, such that HbA1c levels in quitters became comparable with the levels seen in continual smokers three years after quitting.

    Principal investigator Dr Deborah Lycett from Coventry University’s Faculty of Health and Life Sciences said:

    Factors That Can Affect The Accuracy Of Your Blood Test Results

    According to the World Health Organization, chronic diseases kill millions of people each year.

    Diabetes alone accounted for nearly 1.6 million deaths in 2015. Deaths caused by neurodegenerative diseases such as dementia doubled since 2000, and this number is expected to grow in the upcoming years.

    Although these are alarming facts, you might be happy to find out that numerous diseases and injuries, particularly chronic illnesses, can be prevented.

    To prevent a disease, you first need to be aware of it.

    To be aware of it, you need to do the right thing and get your health checked periodically.

    Discovering a predisposition to the disease earlier on gives you a massive advantage. You’ll be able to follow special treatments and minimize its risks or eliminate them.

    But how to get tested for various diseases which might affect you?

    Well, one of the simplest and most efficient ways is by using direct-to-consumer labs. These are usually discount labs you can purchase online at affordable prices and have your general health checked in a matter of days. No doctor visit is required so that you can quickly check your blood tests and monitor your health if you are an educated patient.

    However, you need to keep in mind that there are many factors which can influence the results of your lab tests. In other words, these factors can reduce the accuracy of your results, and that’s why you need to follow up the doctor’s advice before drawing blood for testing.

    What Benefits Could Giving Up Smoking Give To Me As A Diabetic

    Stopping smoking reduces the risk of developing a major diabetes-related complication.

    Many diabetics do not stop because of concerns over weight gain Some studies have proved that the benefits of giving up smoking as a diabetic actually outweigh any negative effects caused by weight gain.

    I Smoke To Keep My Weight Down Isn’t That Good For My Diabetes

    Keeping your weight down is good, that’s true. But the risks of smoking usually outweigh whatever benefit you might get from controlling your weight.

    Yes, smokers tend to weigh less than nonsmokers. Some smokers need fewer calories to feel satisfied with food. Controlling your weight is an important part of managing your diabetes. And eating less can reduce your insulin requirements.

    However, smoking makes it harder to control your blood sugar levels. This makes it more likely you’ll develop complications associated with your diabetes.

    The risk of organ damage from smoking and diabetes add to each other. So over the long term, you’ll have a higher chance of developing heart disease, kidney disease and retinopathy than if you didn’t smoke.

    How Does Smoking Increase My Heart Disease Risk As A Diabetic

    Smoking and diabetes both increase the risk of heart disease in very similar ways, and so when combined, they greatly exacerbate the chances of suffering a heart related condition such as a heart attack or stroke.

    Both high levels of glucose in the blood and smoking damage the walls of the arteries in such a way that fatty deposits can build up much easier. As this occurs, the blood vessels narrow and make circulating blood much harder.

    When this happens to the coronary arteries a heart attack can occur.

    Similarly, a stroke is when not enough blood can get to the brain, and so anything that may limit blood flow increases the risks of a stroke.

    High blood glucose levels also have this effect on the blood vessels and blood flow, so if you smoke when you have diabetes, you are putting yourself at a much greater risk of suffering a heart attack or stroke.

    The Newly Discovered Brain Path Linking Nicotine To Diabetes

    Diabetes: Does Stress Affect Your Blood Sugar Levels?

    The 2019 Monitoring the Future survey finds that around 35 million U.S. adults use cigarettes, about 12 percent of high school seniors use vaping products on 20 or more of the previous 30 days, and over a quarter did so within the past 30 days—an increase  from 11 percent in 2017. Around 2,000 Americans under the age of 18 smoke their first cigarette every day, and over 16 million Americans have smoking-related diseases, including diabetes.1 Diabetes appears at much higher rates in individuals who use tobacco products than in those who don’t. The CDC says that tobacco products elevate the likelihood of developing type 2 diabetes by 30-40 percent, and that use of tobacco products makes managing the condition much more difficult while also increasing the chances of complications, including limb damage, heart disease, and impaired blood flow.2

    Yet it’s not clear to scientists exactly why individuals who use tobacco products face much higher risks of type 2 diabetes , especially when we normally think of weight gain as the cause of the majority of T2DM cases. A recent NIDA-funded study investigated whether certain regions of the brain might play a role in this T2DM risk. It tested the theory that nicotine control causes tobacco addiction through effects on the brain, which may then influence functions of the pancreas, blood sugar, insulin, and diabetes at the same time.

    What did this study find about nicotine and diabetes?

    Why is this important?

    Diabetes And Smoking: Can Smoking Affect Blood Sugar Levels

    Dr. Mahesh. D. M explains, “Smoking directly contributes to diabetes by increasing the risk of developing diabetes by 2 times in those individuals who smoke more than 20 cigarettes per day. Smoking increases insulin resistance, thereby increasing blood sugar levels. Those who are diabetic and still smoke are at 2-3 times greater risk of developing heart disease or stroke than those who do not.”

    Diabetics need to maintain healthy blood sugar levels but if you are a smoker you are making it more difficult to manage diabetes. Smoking also increases an individual’s risk of getting diabetes. Those already suffering from diabetes can experience inflammation, poor immunity, respiratory infections and an increased risk of cardiovascular diseases, heart attack and stroke.

    You must try to quit smoking immediately to control the complications of diabetes. If you find it difficult to quit then you must seek medical help to quit.

    Does Smoking Put Me At A Higher Risk Of Developing Diabetes

    It has been established that there is a clear link between smoking and the risk of developing type 2 diabetes. Nicotine is one of the many chemicals that are found in cigarettes and is what makes smoking so addictive. When you smoke, nicotine changes the chemical processes in the cells inside your body so they do not respond to insulin. This is known as insulin resistance.

    Insulin is the hormone that allows your body to use sugar from the food we eat for energy and stops your blood glucose level from getting too high. If your body starts to become resistant to insulin, then your blood glucose levels will rise and put you at an increased risk of developing type 2 diabetes.

    How Does Smoking Affect My Circulation When I Have Diabetes

    In the same way, both smoking and diabetes affect blood vessels in other parts of your body, so adding both together really increases your risk of conditions linked to poor blood circulation. With diabetes, if you have high blood glucose levels over several years, your blood vessels can become damaged. This can lead to plaque forming in your blood vessels and make it harder for them to deliver enough blood to your cells.Smoking slows down circulation in the smaller blood vessels that supply your hands and feet. Poor circulation increases your risk of:

    • blood vessel blockages in your legs
    • foot and leg amputations.

    Smoking And Diabetes: The Connection Between 2 Us Epidemics

    2017 min

    The increase in diabetes in the U.S. to epidemic levels has gained a lot of attention in recent years. Over 29 million Americans have the disease and many more—1 in 3 adults—are at risk of developing it in the next five years .

    Diabetes and smoking are two of the biggest public health challenges of our time, and they are connected in some surprising ways. Smoking increases the risk of developing diabetes and the risk of organ damage from the disease.

    To learn more about the connection between smoking and diabetes, we turned to the experts behind BecomeAnEX®, a digital quit-smoking program by Truth Initiative® and developed in collaboration with Mayo Clinic.

    Does Drinking Coffee Before Blood Tests Affect The Results

    July 4, 2010 by rfcamat

    Blood tests are among the most important laboratory tests to help diagnose many human diseases. Physical, chemical, and biological properties of the blood give a big picture on the condition of the body. Blood tests can tell if there is a problem on your kidney, heart, liver, glands, brain, muscles, bone marrow, etc. Without blood tests, it would be really hard for doctors to know what’s wrong inside your body. Blood tests are also important in monitoring the effectiveness of the medications you are taking. Blood tests can determine whether the drugs for your hypertension/diabetes/cancer/infection/etc. are working effectively. Examples of blood tests are BUN, LDH, ANA, ESR, GGT, and MPV.

    An accurate blood test result will give an accurate diagnosis. It is therefore important to eliminate possible sources of error for blood test results. Eating and drinking can affect the result of certain blood tests. Doctors require their patients to fast before undergoing blood tests such as cholesterol and glucose blood tests. Patients who habitually drink coffee have one important concern: how does drinking coffee before blood tests affect the results.

    How Does Smoking Affect My Sex Life When I Have Diabetes

    Erectile dysfunction is the inability to get or maintain an erection firm enough for sex. This is common in men who have diabetes, especially those with type 2 diabetes. It can stem from damage to your nerves and blood vessels caused by poor long-term high blood glucose levels.Men with diabetes who smoke are even more likely to have erection problems. When you smoke, chemicals from the cigarette can interfere with the blood flow to your penis and damage the lining of the blood vessels or lead to atherosclerosis . It can also affect the smooth muscle tissue that needs to relax to allow blood to flow in. Nerve damage may also reduce sensation. 

    How Does Smoking Make Me More Likely To Develop Diabetes

    Diabetes Management, WakeMed Health & Hospitals, Raleigh ...

    People with diabetes have bodies that can’t make or use insulin—a hormone that turns glucose from the food you eat into energy. Over time, high blood sugar levels can damage organs such as your kidney, heart, blood vessels and eyes. This damage can cause these organs to malfunction or fail—one reason why diabetes is one of the top 10 causes of death in the country.

    Smoking increases the risk of developing diabetes because it can change how your body processes and regulates sugar. Smoking can also make it harder to control your blood sugar levels if you have diabetes. If you smoke, you have a 30 to 40 percent higher chance of developing diabetes than someone who has never smoked.

    And, the more you smoke, the higher your chance of developing diabetes. Once you quit, your risk of developing diabetes goes down. The longer you’ve been smoke-free, the less likely it is you’ll become diabetic.

    How Does Smoking Affect My Kidneys When I Have Diabetes

    Raised blood glucose in diabetes can also damage the blood vessels in your kidneys. About 1 in 3 people with diabetes will end up with some kidney damage. Diabetic kidney disease is also called diabetic nephropathy.If you smoke, you further increase your risk of kidney disease as it also damages your blood vessel walls.

    Are Electronic Cigarettes Safer Than Normal Cigarettes

    Whilst the safety of e-cigarettes is yet to be well established, they are widely regarded as a safer option compared with cigarettes with the NHS stating that e-cigarettes are “certainly the lesser of two evils”.

    The smoke of conventional cigarettes contains many more dangerous substances, many of which can lead to cancer, including tar, benzene, cadmium and arsenic.

    A review by the United States’ Food and Drug Administration found e-liquids to contain trace levels of cancer causing compounds, such as nitrosamines and formaldehyde, but at a level of about a thousand times lower than cigarettes.

    Nicotine, which is common to both e-cigarettes and conventional cigarettes, increases the risk of narrowing of the arteries and is also very addictive.

    What Other Diabetes Complications Will Smoking Affect

    Further diabetes complications that have been proven to be aggravated by smoking include diabetic nephropathy, albuminuria.

    There are links between smoking and retinopathy, although these are less evident than the cardiovascular risks.

    Smoking is certainly a major risk factor for both the development and progression of diabetic neuropathy.

    How Does Smoking Affect Me If I Already Have Diabetes

    If you have diabetes, smoking increases your chances of dying from any cause compared to non-smokers. It also increases your risk for damage to your organs, as well as your chances for having a heart attack or stroke.

    • Smoking can double your risk of developing kidney damage compared to non-smokers, if you have diabetes. That risk goes down the longer you’ve been quit.
    • Smoking increases the risk of diabetic eye disease . Smoking reduces blood circulation. When this happens to the retina, light sensing cells in the eye are damaged, and causes blindness.
    • Both diabetes and smoking increase your chances of developing cancer of the pancreas. This cancer is fatal in 95% of cases. If you have diabetes and you smoke, your risk of pancreatic cancer is even higher than if you only smoked or were a non-smoking diabetic.
    • Diabetes and cigarette smoking are major risk factors for heart attack and stroke. If you’re diabetic and you smoke, your chances for having a heart attack or stroke are higher than if you were just a smoker, or a non-smoking diabetic. Stopping smoking and controlling your diabetes are incredibly important to lowering your chances of heart attack or stroke.

    Does Nicotine Break Your Fast Nicotine Patches & Gums

    Technically it depends, what is the aim of fasting.

    As you know, nicotine not only arises from your cigarette smoking but also the replacement therapy like nicotine gum and nicotine patches. 

    As nicotine does not increase your blood sugar level that much, hence you are good to smoke in this case. 

    But if you are fasting for the religion like Ramadan fast, Tuesday fast or Monday fast then you should avoid smoking nicotine.

    But for nicotine patches, yes! You can use nicotine patches in religious fast.

    This is because it directly adheres to skin and delivers nicotine directly to the bloodstream that overcomes the disadvantages of nicotine gums and tobacco smoking.

    As you know nicotine gums there is the possibility of reaching nicotine into the stomach that is prohibited in some religious fast like Islamic fast.

    Now again the most asked the question, “Does nicotine break intermittent fasting?”

    No, it won’t break the intermittent fast. In the case of intermittent fasting which is usually for weight loss, nicotine doesn’t seem to break the fast.

    As I stated earlier, nicotine can help you from reducing the carving sensation in your stomach.

    But you should hold yourself not to smoke, as you are degrading your health.

    Bottom Line

    Does Nicotine Gums break’s my fast?

    Yes, it could, because these gums not only have nicotine but also the added sugar which will definitely break your fast even you are fasting for sugar test or for religious norms.
