In the clinic, many diabetic patients insist on taking hypoglycemic drugs, but the blood sugar control is not ideal, what are the reasons? We have summarized 8 common mistakes: 1, do not control the diet: diet therapy is the basis of diabetes treatment, the purpose is to reduce the burden on the pancreatic β-cells to help restore their function. Not controlling the diet and trying to offset it by taking more glucose-lowering drugs is like “whipping a sick horse”, which is wrong and dangerous. 2, according to the conscious symptoms of taking drugs: blood sugar is very high, only then there will be a lot of drinking, urination, eating and weight loss and other typical symptoms of diabetes. Many patients adjust the dosage of hypoglycemic drugs arbitrarily because of no obvious discomfort, resulting in poor blood sugar control. 3, not regular follow-up: some patients do not monitor blood sugar, blood lipids and blood pressure, do not pay attention to the factors affecting their blood sugar and urine sugar changes, do not summarize their own medication rules, but the clouds, follow the trend of taking medication. This is the main reason why our diabetic patients are more seriously ill and have more complications than those in some developed countries. 4.Do not receive insulin treatment when it is time to use insulin. 5, do not understand the characteristics of oral hypoglycemic drugs: for example, the effect of some sulfonylurea hypoglycemic drugs gradually increases with time, so you can not rush to change the drug. Moreover, each glucose-lowering drug has a maximum effective dose. Do not use the maximum effective dose, do not jump to conclusions. 6, think that the high price of the drug is a good drug: there is no question of which drug is better, the scientific argument is which is a more suitable hypoglycemic drugs. The drug that is effective for A is not necessarily effective for B, and may even be harmful. 7, the pursuit of diabetes can “go to the root” of the special drugs: some patients even in the case of good control of blood sugar, stop the current stage of effective treatment, but to find the “magic pill”. The comprehensive treatment of diabetes, including diet, exercise and medication, is the crystallization of people’s wisdom in their long struggle with diabetes, and is a method that has been strictly proven to be effective. 8, blindly worry about the side effects of drugs: some people believe that taking drugs for a long time will damage the liver and kidney function. In fact, the dose of hypoglycemic drugs is safe as long as it is within the range of the pharmacopoeia. Side effects are only seen in individual patients, and the side effects disappear after stopping the medication and do not bring serious effects. In fact, the consequences of uncontrolled hyperglycemia are much more serious compared to the possible side effects of taking medication. Therefore, the majority of patients should consult more specialists, make efforts to learn knowledge and overcome the blindness of treatment in order to really manage their health well.
