Having diabetes in your 30s must be taken seriously, as young people who develop diabetes can suffer complications earlier. It can seriously affect the quality of life and also reduce the life expectancy of the patient. Once a patient is diagnosed with diabetes, he or she must adopt a scientific and regular lifestyle. First of all, the diet should be strictly controlled, with three meals a day, with no more than 100 grams of staple food per meal and no high-calorie foods. If the patient feels hungry, he or she can eat more green leafy vegetables as well as carrots and onions. You can drink 200mL of milk every day, preferably between meals or before bedtime. Diabetic patients must eat a light and easily digestible diet, the main food can be rice, steamed buns, rolls and so on. Secondly, you should exercise properly, young people around 30 years old can exercise at least one hour a day. This can increase the sensitivity of insulin and help to lower blood sugar as soon as possible. This will reduce the occurrence of complications, prolong the life span of the patient and improve the quality of life of the patient.
