Insulin how does it lower blood sugar




















Insulin is the main regulator of sugar in the bloodstream. This hormone is made by beta cells and continuously released into the blood stream. Beta cells are found in the pancreas, which is an organ behind the stomach. Insulin levels in the blood stream are carefully calibrated to keep the blood glucose just right.

High insulin levels drive sugar out of the bloodstream into muscle, fat and liver cells where it is stored for future use. Low insulin levels allow sugar and other fuels to be released back into the blood stream. Overnight and between meals, insulin levels in the blood stream are low and relatively constant. These low levels of insulin allow the body to tap into its stored energy sources namely glycogen and fat and also to release sugar and other fuels from the liver. This overnight and between-meal insulin is referred to as background or basal insulin.

When eating, the amount of insulin released from the pancreas rapidly spikes. This burst of insulin that accompanies eating is called bolus insulin. The high levels of insulin help the sugar get out of the blood stream and be stored for future use. There are other hormones that work together with insulin to regulate blood sugar including incretins and gluco-counterregulatory hormones, but insulin is the most important.

Self-assessment Quiz Self assessment quizzes are available for topics covered in this website. The human body wants blood glucose blood sugar maintained in a very narrow range. Insulin and glucagon are the hormones which make this happen. Both insulin and glucagon are secreted from the pancreas, and thus are referred to as pancreatic endocrine hormones. The picture on the left shows the intimate relationship both insulin and glucagon have to each other.

Note that the pancreas serves as the central player in this scheme. It is the production of insulin and glucagon by the pancreas which ultimately determines if a patient has diabetes, hypoglycemia, or some other sugar problem. They are both secreted in response to blood sugar levels, but in opposite fashion!

Insulin is normally secreted by the beta cells a type of islet cell of the pancreas. The stimulus for insulin secretion is a HIGH blood glucose Although there is always a low level of insulin secreted by the pancreas, the amount secreted into the blood increases as the blood glucose rises.

Similarly, as blood glucose falls, the amount of insulin secreted by the pancreatic islets goes down. As can be seen in the picture, insulin has an effect on a number of cells, including muscle, red blood cells, and fat cells. In response to insulin, these cells absorb glucose out of the blood, having the net effect of lowering the high blood glucose levels into the normal range. Glucagon is secreted by the alpha cells of the pancreatic islets in much the same manner as insulin If blood glucose is high, then no glucagon is secreted.

Adapted from The Carb Sensitivity Program It is no exaggeration—balancing your blood sugar could be a matter of life or death. Chronic high blood sugar levels are toxic to your body, destroying organs and blood vessels and paving the way to a heart attack, type 2 diabetes, stroke, dialysis, nerve damage, erectile dysfunction, or even blindness.

The good news? Out-of-control sugar levels can be reigned in and regulated with the right foods. Here are most potent blood sugar-lowering foods so you know how to lower blood sugar levels naturally. Blood Sugar Benefit: A groundbreaking study published in the Journal of Nutrition in found a daily dose of the bioactive ingredients from blueberries increases sensitivity to insulin and may reduce the risk of developing diabetes in at-risk individuals.

That's important because too many carbs produces too much insulin, which could lead to insulin resistance and type 2 diabetes. Adding blueberries to daily smoothies for six weeks also improves insulin sensitivity, so feel free to eat healthy doses of the superfood fruit, too. Added Perk: Low in naturally occurring sugars, blueberries are also packed with antioxidants that fight damage from free radicals, accelerated aging, and diseases like cancer and Alzheimer's.

Blood Sugar Benefit: Don't let the fat content of avocados fool you—they're still good for you! Avocados are full of monounsaturated fat, the kind that helps slow the release of sugars into the bloodstream, prompting less insulin release, and can even help to lower your cholesterol. Added Perk: Avocados contain beta-sitosterol, a compound that could help quell inflammation after an intense workout.

Just limit yourself to one-quarter of an avocado at a time to avoid calorie overload. Getting Started When most people find out they have Type 2 diabetes, they are first instructed to make changes in their diet and lifestyle.

These changes, which are likely to include routine exercise, more nutritious food choices, and often a lower calorie intake, are crucial to managing diabetes and may successfully lower blood glucose levels to an acceptable level. If they do not, a drug such as glyburide, glipizide, or metformin is often prescribed. But lifestyle changes and oral drugs for Type 2 diabetes are unlikely to be permanent solutions.

Ultimately, insulin injected or infused is the most effective treatment for Type 2 diabetes. There are many barriers to starting insulin therapy: Often they are psychological; sometimes they are physical or financial. But if insulin is begun early enough and is used appropriately, people who use it have a marked decrease in complications related to diabetes such as retinopathy a diabetic eye disease , nephropathy diabetic kidney disease , and neuropathy nerve damage.

The need for insulin should not be viewed as a personal failure, but rather as a largely inevitable part of the treatment of Type 2 diabetes. This article offers some practical guidance on starting insulin for people with Type 2 diabetes. HbA1c stands for glycosylated hemoglobin and is a measure of blood glucose control.

Jensen, Ph. Although it has long been known that fruits, vegetables, and grains are excellent sources of the vitamins and minerals that are so essential to good health, we continue to learn about the importance of supplementing our diets no matter how healthful they may be with additional amounts of certain nutrients.

The objectives of nutritional supplementation are fourfold: To compensate for the declining ability of our aging digestive systems to make certain dietary nutrients available to the rest of our bodies—thus preventing potentially harmful deficiencies. To achieve above-normal levels of some nutrients so as to extract as much health benefit from them as possible—thus helping to prevent chronic diseases.

There are different types of diabetes—type 1, type 2 and gestational diabetes. If you have diabetes—type 1, type 2 or gestational—your body either doesn't make enough insulin, can't use the insulin well, or both. Learn more about blood sugar Learn more about insulin. In type 1 diabetes, your immune system mistakenly treats the beta cells in your pancreas that make insulin as foreign invaders and destroys them.

This can happen over a few weeks, months, or years. When enough beta cells are gone, your pancreas stops making insulin or makes so little insulin that you need to take insulin to live. Type 1 diabetes develops most often in young people but can also appear in adults.

If you have type 2 diabetes, your body does not use insulin properly. Estrogen in birth control pills can affect the way a person with diabetes may respond to insulin.

The American Diabetes Association advises women with diabetes to use a birth control pill containing norgestimate and a synthetic estrogen.

The ADA also says birth control injections and implants are safe for women with diabetes, but suggests they still have some effect on blood sugars. If women elect to use these birth control methods, they should monitor their blood sugar levels, especially for several weeks when these agents are first administered. Women with diabetes should discuss their birth control options with their doctor.

Lantus is the man made form of a long acting insulin that is given by injection to diabetic patients, to lower their high blood sugar levels. Your blood sugar tends to fluctuate throughout the day. Itll be lower when you first wake up, especially if you havent eaten for the past 8 to 10 hours. Your blood sugar will go up once you eat. Depending on when you last ate, heres whats considered to be a normal blood sugar range:.

The point at which low blood sugar symptoms become noticeable is different from one person to the next. Other people may not feel any symptoms until well below that mark. A quick, simple blood test can measure your blood sugar level. If you have diabetes or another medical condition that sometimes causes episodes of low blood sugar, its important to regularly check your blood sugar with a home test.

Symptoms of low blood sugar vary from person to person and can even be different from one episode to the next. You may experience specific symptoms the first time your blood sugar dips, and different symptoms the next time.

Physical activity makes you more sensitive to insulin, one reason why its a cornerstone of diabetes management. Dont wait until youre diagnosed with diabetes to start moving more. The earlier you take action , the better off youll be. Weight loss is important too, as is avoiding high blood sugar , reducing stress , and getting enough sleep. These lifestyle changes really work. Talk with your health care provider about how to get started.

Diabetes is a problem with your body that causes;blood;sugar ;levels to rise higher than normal. This is also called;hyperglycemia. When you eat, your body breaks food down into sugar;and sends it into the blood.

Insulin then helps move the sugar from the blood into your cells. When;sugar enters your cells, it is either used as fuel for energy right away or stored for later use. In a person with diabetes, there is a problem with;insulin.

But, not everyone with diabetes has the same problem. There are different types of diabetestype 1, type 2;and gestational diabetes.
