Strenuous exercise is generally not recommended for diabetic patients because strenuous exercise significantly increases the body’s consumption, especially of sugar. For many diabetics, especially type 1 diabetics, it is very likely to lead to hypoglycemia, which can seriously lead to coma. Therefore, it is not recommended for diabetic patients to perform intense exercise, but only appropriate moderate exercise, like jogging, swimming, cycling, aerobics, etc. And it is best for diabetic patients to perform appropriate activities 2h after meals, which is good for health and can also reduce blood sugar after meals. It is definitely not recommended for diabetic patients to do any physical activity in fasting state, which will significantly increase the incidence of hypoglycemia.
