What is the relationship between obesity and diabetes?

Diabetes is a common endocrine and metabolic disease and has become an important epidemic disease that threatens the health of all human beings. Among them, obesity is an important factor in the development of diabetes (mainly type 2 diabetes). Among the long-term obese people, the prevalence of diabetes is 4 to 5 times higher than that of ordinary people. In addition, 80% of people with type 2 diabetes are obese.

What is the relationship between obesity and diabetes?

Obesity is caused by changes in the body, excess substances are converted into fat, resulting in excessive body fat, exceeding normal physiological needs. Generally, 10% of the normal body weight is overweight, 20% of the standard weight is obese, and 20% of the standard weight is weight loss.

Obese patients have relatively few insulin receptors on adipocytes and are not sensitive to insulin. Although there is enough insulin to play a role, it brings a burden to the body, not only easy to induce diabetes, but also prone to high blood pressure, high blood fat, stroke, coronary heart disease, endocrine disorders and so on.


Some people can suddenly eat and drink, the weight does not increase and fall, self-righteous is a successful weight loss, but the overall inspection is dumbfounded, it turned out to have diabetes. Some thin people have high blood lipids and high blood pressure. When they worry about getting diabetes, some people are comforting him: "Nothing, people who are diabetic are fat, you can't get it, rest assured!" Visible, the relationship between diabetes and weight There are many misunderstandings on the issue.

Type 1 diabetes is more "like thin"

Patients with type 1 diabetes are more common in adolescents. Because of insufficient insulin, the body is not easy to store energy. The pre-existing body weight is normal or low, and the body weight is significantly decreased after the onset. Such patients need lifelong insulin treatment, after reasonable treatment, they can gradually "fat" until normal weight.

Type 2 diabetes patients "have fat and thin"

In general, patients with type 2 diabetes have a "history" of obesity. After the onset, the body weight is reduced, but the weight base is large, so it is not obvious. In the absence of deliberate dieting, weight loss of more than 2 kg in a month, you must be alert to diabetes, it is best to go to the hospital to check blood sugar.


Type 2 diabetes accounts for 90% of all diabetes, 80% of which are associated with obesity, so it is also known as "sugar fat" or "glycolipid disease". The pathogenesis of obese patients is mainly insulin resistance. On the one hand, obese people have more fat cells, fat cells are not sensitive to insulin; on the other hand, they are often accompanied by dyslipidemia, increased free fatty acids, and easy to form insulin resistance. In countries such as Europe and the United States, patients with type 2 diabetes are basically fat, but in China and other Asian countries, the rate of obesity in patients with type 2 diabetes is not so high. Therefore, people who are slightly overweight should also be alert to the "invasion" of diabetes.

"Being thin and fat inside," be more vigilant

Some people don't look fat, but the number of visceral fat cells and the fat volume are high, which is expressed as "thin and fat." This type of person has a large waist circumference and is also called "abdominal obesity." They often have different levels of insulin resistance. If you do not limit your diet or exercise to reduce visceral fat accumulation, you may cause islet cells to be damaged, which may lead to diabetes.

Losing weight is the key to treating diabetes

For obese patients with type 2 diabetes, insulin resistance is reduced by reducing body weight. Eat more coarse grains, fresh vegetables and fruits, eat less fried foods, convenience foods, fast food, etc., control salt and sugar intake, all help to lose weight. Usually pay more attention to diet, it is best to develop a plan, every week's diet, which time period should be exercised, thus enhancing their resistance.
