Activating insulin here should mean increasing insulin sensitivity, decreasing insulin resistance, and stimulating insulin secretion. Patients can activate insulin through food, exercise and drugs. 1. Diet: control weight and reduce insulin resistance. Diet control, you need to eat regularly and quantitatively, balanced nutrition, reasonable combination, cooking less oil and salt, less porridge, avoid fried snacks, eat more vegetables and fruits, reduce staple food. Quit smoking and drinking. 2. Exercise: Exercise can increase the sensitivity of insulin receptors on the cell membrane. Exercise should be mainly aerobic exercise, such as walking, climbing, playing tai chi, doing aerobics, etc. The amount of exercise should be increased from a small amount. 3. Drugs: Drugs that activate insulin are divided into oral and injectable drugs. Injectable drugs that stimulate insulin secretion, such as GLP-1 receptor agonists, can stimulate insulin secretion in a glucose concentration-dependent manner. Oral drugs that stimulate insulin secretion, including sulfonylureas as well as non-sulfonylurea, glargine-based hypoglycemic agents, can stimulate insulin secretion. To summarize, insulin can be activated by diet, exercise, and drugs.
