Patients with impaired glucose tolerance can be adjusted through lifestyle modification, reasonable diet and proper exercise. Impaired glucose tolerance refers to a state of abnormal glucose metabolism in which normal blood glucose gradually transitions to diabetes, and patients may experience abnormally high fasting or postprandial blood glucose. In daily life, patients with impaired glucose tolerance should have a balanced diet, avoid excessive intake of high-sugar, high-fat, high-cholesterol foods, focus on light and easy-to-digest foods, add dietary fiber foods and quit smoking and drinking. In addition to a reasonable diet, patients should exercise properly to maintain a healthy body weight, promote body metabolism and enhance immunity. Ensuring sufficient rest time, avoiding overwork or staying up late for a long period of time, and maintaining a positive and optimistic mindset are all beneficial to the improvement of impaired glucose tolerance. Once diagnosed with impaired glucose tolerance, patients need to take into account their own situation and ask their doctors for guidance. And cooperate with the doctor to take treatment measures.
