When it comes to managing blood sugar levels, there are several factors that can influence our overall health. One often-overlooked aspect is smoking. While many people know about the risks associated with smoking on cardiovascular and respiratory health, its impact on blood sugar levels may not be as widely understood.
Understanding the Complex Relationship Between Smoking and Blood Sugar
Smoking has been shown to have a significant effect on insulin sensitivity, which can lead to increased blood sugar levels over time. In fact, research suggests that smokers are more likely to develop type 2 diabetes than non-smokers (1). This is because smoking damages the pancreas' ability to produce insulin and also reduces the body's ability to use existing insulin effectively.
The Impact of Smoking on Insulin Sensitivity
When you smoke, your body becomes less responsive to insulin. As a result, glucose builds up in your bloodstream instead of being absorbed by cells for energy (2). This increased blood sugar level can have serious consequences for people with diabetes or those at risk of developing the condition.
Quitting Smoking: The Key to Regaining Blood Sugar Balance
Fortunately, quitting smoking is often accompanied by improvements in insulin sensitivity. Within six months after quitting, studies show that smokers' ability to process glucose improves (3). By giving up cigarettes and adopting a healthier lifestyle, individuals can take control of their blood sugar levels and reduce the risk of developing type 2 diabetes.
The Connection Between Smoking Cessation and Weight Loss
Losing weight is another key aspect of managing blood sugar levels. Research has consistently shown that smoking cessation leads to significant weight loss in many people (4). Since carrying excess weight can put additional pressure on your pancreas, shedding pounds can help alleviate insulin resistance and improve overall glucose control.
Combining Smoking Cessation with Healthy Lifestyle Choices
While quitting smoking is a vital step towards regaining blood sugar balance, it's essential to combine this with other healthy lifestyle choices. Eating a balanced diet rich in fruits, vegetables, whole grains, lean proteins, and fiber can help support optimal insulin function (5). Exercise also plays an important role – regular physical activity helps your body use glucose for energy and improves insulin sensitivity.
Conclusion: Taking Control of Blood Sugar Levels
Quitting smoking is just the first step towards regaining control over blood sugar levels. By adopting a healthy lifestyle, managing stress effectively, and getting enough sleep, individuals can work towards optimal health outcomes. Remember that even small changes can have significant benefits – so start by setting achievable goals today!

If that’s the case, you may need medication. Treatment how can you lower blood sugar levels for diabetes is focused on keeping blood sugar (glucose) levels at a normal range. In people with Type 1 diabetes, the body makes little to no insulin, which means taking insulin (usually by injection) is necessary. For those with Type 2 diabetes, in which the body is unable to properly use insulin, too much glucose is often produced, so the first line of treatment might be an oral medication such as metformin, which lowers blood glucose levels. Metformin, explains Yetunde Asiedu, MD, a Yale Medicine primary care physician, also helps the 395 blood sugar level body respond better to its own insulin. “It’s a popular medication because it's effective at treating diabetes and the cost is low,” she says. “That is usually our first go-to, but if you’ve had a heart attack or you have congestive heart failure, there are specific types of diabetes medications that may be even better for you.” There are even medications for diabetes that can help with weight loss. A class of drugs called GLP-1 (glucagon-like peptide-1) restores the signal to your brain that you are full after you eat, a signal that is believed to be less sensitive in people with diabetes, explains Edgar Albuja, a Yale clinical pharmacist. The medication also slows down digestion so that sugar isn’t absorbed as fast in the bloodstream, helping the body to produce its own insulin. “These medications are injectable, 74 blood sugar level but they're not insulin. And most of them require injections just once a week. It's a little bit easier to take than let's say, once-daily insulin injections,” says Kasia Lipska, MD, MHS, a Yale Medicine endocrinologist. So, what’s the right medication for you? That, she says, will be the one you will take regularly, gives you the least side effects, and works best at reducing your blood sugar levels and risk of complications. Taking your diabetes medications is of the utmost importance and if there are any problems that make this difficult for you, talk to your pharmacist, Albuja says. “They can help you figure out how to manage your medications—the important thing is to take your medication.”
