In fact, diabetes can be very well controlled, through regular scientific treatment can prevent or delay the heart, brain, kidney and other complications. Today, we want to emphasize a few misconceptions: 1, diabetes began when the majority of patients do not have obvious discomfort, so many patients do not pay attention to, and even think that can eat and drink is good, do not take scientific methods to control blood sugar, and eventually appeared because of high blood sugar and caused heart, brain and kidney damage, it is too late to mend the fold. 2.Insufficient understanding of the danger of hypoglycemia. Research shows that the damage of hypoglycemia to the heart, brain and other organs is fatal. Can instantly appear myocardial infarction, or sudden death. Hypoglycemic coma can lead to irreversible damage to brain cells and even brain death. Elderly people with cardiovascular disease should be more relaxed in controlling blood sugar, fasting blood sugar <7.0MMOL/L, 2 hours after meal <10.0MMOL/L can be. 3, the medication should not believe in advertising so-called special-effect hypoglycemic drugs, or pure Chinese medicine hypoglycemic, because if these really hypoglycemic effect is particularly good, then must be mixed with different western drugs, the amount of western drugs and ominous ingredients, easy to cause blood sugar fluctuations, and cause adverse consequences.
