The generic name for Bayerisin is acarbose. Taking it and farting all the time can be solved by reducing the dosage, starting with a small dose, and combining it with other hypoglycemic drugs. Acarbose is a commonly used hypoglycemic agent, and the mechanism of hypoglycemia is to reduce the patient’s postprandial hyperglycemia by delaying the absorption of carbohydrates. Gastrointestinal flatulence is a common adverse effect of acarbose. Patients can reduce the dosage to alleviate the situation of excessive gas; or gradually increase the dosage from a small dose when starting to take acarbose to lower blood glucose; and can also be used in combination with other glucose-lowering drugs such as DPP-4 inhibitors (e.g., selegiline). However, if diabetic patients need to adjust the dose or type of hypoglycemic drugs, it is recommended to do so under the guidance of a doctor. In addition, patients should eat less gas-producing food, such as sweet potatoes, yams, soybeans, etc., during the period of taking acarbose, which can also reduce the appearance of farting symptoms to a certain extent. The common adverse reactions to acarbose are gastrointestinal reactions, such as flatulence, bowel sounds, diarrhea and so on. It is contraindicated for those who are allergic to the product, children, patients with chronic gastrointestinal dysfunction with obvious dyspepsia and absorption disorders, and patients with severe renal insufficiency. For patients with poor liver function, liver function should be monitored during drug administration. When always farting occurs during taking acarbose, it is recommended to go to the hospital to consult a professional doctor and adjust the medication regimen under the doctor’s guidance.
