Insulin is the most potent glucose-lowering drug, and many diabetics need insulin to control their condition. However, it is said that the use of insulin can lead to obesity, and obesity itself is prone to cause diabetes, so wouldn’t this hinder the control of diabetes? Why does insulin cause obesity in diabetic patients? 1, insulin is like a “key”, it can open a variety of cell membranes in the body on a “door” to promote the circulation of glucose into the cells to maintain the normal physiological activities of the body, of course, it can also promote energy storage. Once the calorie intake exceeds the physiological activities required for a day, insulin can promote the conversion of this excess energy into fat stored in adipose tissue and liver, people will grow “fat”. 2, however, not necessarily fat insulin, the key depends on whether the use of insulin is reasonable, as well as the control of diet and exercise. Some patients may have too large a dose of insulin, prone to hypoglycemia, increased hunger, resulting in increased eating; some patients after the insulin, diet control is not strict, eating more, but also no proper exercise or exercise less. Doctor’s tip: Doctors should consider this problem in medication matching and use medication reasonably, while patients should also pay attention to reasonable diet and exercise under the guidance of doctors, which can reduce insulin-induced obesity.
