Many diabetic patients are accustomed to rely only on oral hypoglycemic drugs to control blood sugar, experts reminded that oral hypoglycemic drugs need to get out of the 7 major misconceptions. 1, ignore the diet treatment some patients hope not to control the diet, but by taking more glucose-lowering drugs to control the condition, which is wrong, and even dangerous. Clinical practice has fully proved that, without a good diet, excessive blood sugar fluctuations will certainly accelerate the occurrence and development of diabetes complications, relying only on oral hypoglycemic therapy is usually a failure. 2, not according to the blood sugar level to adjust the dosage of hypoglycemic drugs some patients feel that they have taken the drug, it is safe, often ignore according to their blood sugar level to adjust the amount of medication. This will greatly affect the efficacy of the medication. 3, rarely to the hospital follow-up or examination experts found that some patients rarely follow-up, not often check blood sugar, blood lipids and blood pressure. This makes it impossible to understand the effect of taking medication and the factors that affect their blood sugar changes. 4, think that all people taking oral hypoglycemic drugs are effective oral hypoglycemic drugs are not effective for all people, but a considerable number of diabetic patients are not willing to accept insulin therapy even when taking oral hypoglycemic drugs are not effective or even ineffective. 5, anxious to change some oral hypoglycemic drugs in the body with the extension of time, the process of drug action gradually enhanced. Some patients do not understand this point, often taking a few days, see blood glucose drop is not obvious, it is eager to change the drug. In fact, some glucose-lowering drugs can reach their maximum effect when they are taken for half a month or even a month. Some patients listen to wild advertisements and believe in ancestral recipes, resulting in spending a lot of money, but the condition has worsened, delaying treatment. 6, ignore the safety and efficacy of drugs some patients tend to focus on the treatment effect, but ignore the safety of oral hypoglycemic drugs. Especially the elderly type 2 diabetes patients in the choice of drugs, should ensure the efficacy, but also should pay attention to the incidence of hypoglycemia, liver and kidney function safety, the impact on weight, cardiovascular protection benefits. 7, do not pay attention to weight changes experts reminded that for patients with heavy obesity, should first reduce weight, and then according to the blood glucose index selection of hypoglycemic drugs.
