What is the real cause of type 2 diabetes?

Because these cells don't interact normally with insulin, they don't absorb enough sugar. The real cause of diabetes is excess insulin, not excess blood sugar. In other words, high blood sugar is a symptom, but not the root cause. Body mass index (BMI) is a number calculated from a person's weight and height.

Most health professionals rely on BMI to assess whether their patients are overweight (BMI of 25 or greater) or obese (BMI of 30 or greater). All overweight adults should talk to their doctor about being tested for type 2 diabetes. Before developing type 2 diabetes, most people have prediabetes, where blood sugar levels are higher than normal, but not yet high enough to be diagnosed with type 2 diabetes. People who have prediabetes have a higher risk of developing type 2 diabetes.

If you have prediabetes, losing a small amount of weight if you're overweight and getting regular physical activity can reduce your risk of developing type 2 diabetes. A lifestyle change program offered through the CDC-led National Diabetes Prevention Program can help you make those changes and keep them sustained. Through the program, you can reduce your risk of developing type 2 diabetes by up to 58% (71% if you are 60 or older). You are more likely to develop type 2 diabetes if you are not physically active and are overweight or obese.

Excess weight sometimes causes insulin resistance and is common in people with type 2 diabetes. The location of body fat also makes a difference. Excess belly fat is linked to insulin resistance, type 2 diabetes, and heart and blood vessel disease. To see if your weight puts you at risk for type 2 diabetes, see these body mass index (BMI) charts.

Type 2 diabetes usually starts with insulin resistance, a condition in which the muscles, liver, and fat cells don't use insulin well. As a result, the body needs more insulin to help glucose enter cells. At first, the pancreas produces more insulin to meet the additional demand. Over time, the pancreas can't produce enough insulin and blood glucose levels rise.

Hormones produced by the placenta contribute to insulin resistance, which occurs in all women in late pregnancy. Most pregnant women can produce enough insulin to overcome insulin resistance, but some don't. Gestational diabetes occurs when the pancreas can't produce enough insulin. As with type 2 diabetes, excess weight is linked to gestational diabetes.

Overweight or obese women may already have insulin resistance when they become pregnant. Gaining too much weight during pregnancy can also be a factor. Some hormonal diseases cause the body to produce an excessive amount of certain hormones, which sometimes cause insulin resistance and diabetes. Insulin resistance and high blood glucose levels are thought to be the cause of type 2 diabetes.

The pancreas produces a hormone called insulin. Helps cells convert glucose, a type of sugar, from the foods you eat into energy. People with type 2 diabetes produce insulin, but their cells don't use it as well as they should. It's true that being overweight is a risk factor for developing type 2 diabetes, but family history, age, and race are also a risk factor.

Type 2 diabetes develops when the pancreas produces less insulin than the body needs and the body's cells stop responding to insulin. People of Asian descent in the normal weight range may have too much visceral fat and be at risk for type 2 diabetes with a lower BMI. The theory proposed that type 2 diabetes results from the accumulation of fat in the liver, which induces insulin resistance and increases blood sugar production. The genetic fault you inherit is not a type 2 diabetes gene (which has never been found) but its fat storage capacity.

While prediabetes and diabetes may look like different conditions, the reality is that they are actually the same disease with the same risks. My opinion is that type 2 diabetes is not a hormonal disease but a nutritional condition, caused by excessive consumption of cultivated grains and grain-based foods. This means that type 2 diabetes could, in fact, have molecular causes that are independent of insulin and blood sugar. Type 2 diabetes occurs when insulin production increases, but there is insulin resistance and the individual has signs and symptoms of diabetes.

You can prevent or delay type 2 diabetes with proven and achievable lifestyle changes, such as losing a small amount of weight and getting more physical activity, even if you're at high risk. Type 1 diabetes occurs when the immune system, the body's system that fights infections, attacks and destroys the insulin-producing beta cells in the pancreas. Type 1 is the result of a dysfunctional pancreas, which produces minimal or no insulin and usually occurs in childhood. In type 2, the pancreas doesn't make enough insulin, and the insulin it produces doesn't always work as it should.
