What are the side effects of nationally recognized weight loss drugs

National approved weight loss drugs may have side effects such as gastrointestinal discomfort, cardiovascular risk, metabolic disorders, neurological reactions, and liver and kidney function damage. Weight loss pills should be used strictly according to medical advice. Common side effects include fat diarrhea caused by orlistat, increased heart rate caused by phenytoin hydrochloride, and hypoglycemia caused by liraglutide.

1. Gastrointestinal discomfort

Orlistat, as a lipase inhibitor, may cause fat diarrhea, urgency of defecation, or oily spots. Some patients may experience gastrointestinal symptoms such as bloating and increased gas output, which are related to the mechanism of medication blocking dietary fat absorption. It is recommended to control oil intake during medication, as long-term use may affect the absorption of fat soluble vitamins.

2. Cardiovascular risk

Central appetite suppressants such as fentanyl hydrochloride may increase blood pressure, heart rate, and pose a risk of palpitations or chest tightness. Cardiovascular disease patients should avoid using such drugs, and regular monitoring of blood pressure and electrocardiogram changes should be conducted during medication to avoid exacerbating cardiac burden when taking caffeine containing products.

3. Metabolic disorders

GLP-1 receptor agonists such as liraglutide may trigger hypoglycemic reactions, especially when used in combination with hypoglycemic drugs. Some patients have electrolyte imbalance or increased uric acid. During the use of diabetes, blood glucose monitoring should be strengthened, and diet and medication programs should be adjusted in time.

4. Neurological response

Weight loss drugs such as bupropion that act on the central nervous system may cause insomnia, dizziness, or headaches. A small number of patients may experience emotional fluctuations, anxiety, and other mental symptoms. Patients with depression should use it with caution, and if severe mental symptoms occur, they should immediately stop taking the medication and seek medical attention.

5. Liver and kidney function damage

The metabolic process of some weight loss drugs may increase the burden on the liver and kidneys, manifested as elevated transaminase or abnormal creatinine. Before medication, it is necessary to evaluate the baseline liver and kidney function, and regularly review relevant indicators during medication to avoid the simultaneous use of other drugs with liver toxicity.

The use of regular weight loss drugs must be carried out under the guidance of a doctor, and strict screening of medication contraindications is required. During the medication period, it is recommended to maintain a balanced diet and moderate exercise, drink no less than 1500 milliliters of water per day, and regularly monitor changes in weight and body fat percentage. If serious side effects such as chest pain, jaundice, or persistent vomiting occur, stop taking the medication immediately and seek medical attention. Weight loss pills are only used as auxiliary means and need to be adjusted with lifestyle to achieve long-term healthy weight loss effects, avoiding unauthorized increase or decrease in dosage or extension of treatment course.
