Insulin translates unfavourable lifestyle into obesity. Insulin sensitivity and obesity

Insulin sensitivity and obesity -

Over time, the pancreas keeps trying to regulate the blood sugar, producing more and more insulin until it wears out and can't produce large amounts of insulin anymore. As a result, blood sugar levels increase to the point of being in the diabetic range. Anyone can become insulin-resistant.

In particular, people with excess weight are at a higher risk, compared to the general population. Risk is further increased with a family history of type two diabetes, age over 45, African, Latino or Native American ancestry, smoking, and certain medications, including steroids, anti-psychotics, and HIV medication.

There are other medical conditions associated with insulin resistance, like obstructive sleep apnea, fatty liver disease, polycystic ovarian syndrome, also known as PCOS, Cushing's syndrome, and lipodystrophy syndromes. Lipodystrophy syndromes are conditions that cause abnormal fat loss.

So carrying either too much or not enough fat tissue in your body can be associated with insulin resistance. Very often people with insulin resistance don't have any symptoms at all. It is usually picked up by their doctor during an annual health exam or routine blood work.

There are some signs of insulin resistance that your doctor may look for. These includes a waistline over 40 inches in men, and a waistline over 35 inches in women. Skin tags or patches of dark velvety skin called acanthosis nigricans.

A blood pressure reading of over 80 or higher. A fasting glucose level equal or above milligrams per deciliter. Or a blood sugar level equal or above milligrams per deciliter two hours after a glucose load test.

An A1C between 5. A fasting triglycerides level over milligram per deciliter. And an HDL cholesterol level under 40 milligrams per deciliter in men, and an HDL cholesterol level under 50 milligrams per deciliter in women. Or more recently, a blood test called hemoglobin glycosylated A1C, often simply referred to as A1C.

Reversing insulin resistance and preventing type two diabetes is possible through lifestyle changes, medication, or sometimes both. Healthy bodies come in different shapes and sizes. Losing weight through drastic means can be dangerous and counterproductive. Instead, get ideas from a doctor or a nutritionist about ways to incorporate healthy foods like fruits, vegetables, nuts, beans, and lean proteins into your meals.

Also, consider incorporating exercise and movement into your day-to-day life in ways that make you feel good. Even though permanently defeating insulin resistance isn't always possible, you can help your body to be more receptive to insulin.

Listen to your body, reduce stress, give it the nutrition and activity it desires. If you'd like to learn even more about insulin resistance, watch our other related videos or visit mayoclinic.

Lee adds. Your doctor may recommend a low-carb diet, regular exercise and even medication to help you overcome insulin resistance.

But first you need to know if you have this condition. Lee says. The pancreas reacts by producing more insulin to try to keep up with higher blood sugar levels. This condition is known as hyperinsulinemia.

If your cells become too resistant to insulin, it can result in elevated blood sugar levels, which can lead to weight gain, prediabetes and type 2 diabetes. Losing weight with insulin resistance is more difficult because the body stores excess blood sugar as fat.

Excess body fat — especially around the waist — and lack of physical activity are primary causes of insulin resistance. A diet of highly processed carbohydrate foods and saturated fats is another contributor. Certain medications and genetic conditions can also cause it.

Dietary changes , physical activity and even some medications can help reduce both blood glucose and insulin levels. Low-carb diets that emphasize healthy sources of carbs, fat and protein can reduce insulin resistance.

While this much is agreed, closer examination shows just how much confusion still reigns in the detail. Insulin, a hormone made by the pancreas, helps the body use glucose for energy. This causes the pancreas to work harder to produce more insulin. Years of overwork lead to exhaustion of insulin-producing cells, which start to die, and Type 2 diabetes develops.
