First of all, I hope you can tell me what diet pills you are taking and what its active ingredients are. The situation you are talking about should be similar to stimulants or inhibitors. It is recommended to stop taking the medicine first and consult a professional before handling it.

I make a list of diet pills (active ingredients) that have been banned, and you can also compare them.

Sibutramine: inhibits the reuptake of norepinephrine, 5- hydroxytryptamine and dopamine, enhances satiety and inhibits appetite. Can cause serious adverse reactions of the heart and nervous system. 1997 was approved for marketing by FDA, and 20 10 was removed from the European Union and the United States. On October 30th of that year, the production, sale and use in China also stopped.

Thyroxine: metabolism promoter, increasing energy consumption. It can lead to tachycardia, menstrual disorder, tremor and other side effects. Thyroxine has never been approved for weight loss.

Amphetamines: central nervous system inhibitors. It is addictive and can lead to high blood pressure, headache and mental disorders.

Fenfluramine: Amphetamine appetite suppressant. It will lead to serious adverse reactions, such as heart valve injury and pulmonary hypertension. Fenfluramine was approved by FDA on 1973, and its marketing license was revoked on 1997.

Clenbuterol: It can promote fat decomposition and increase muscle content. Can cause muscle tremor, electrolyte disorder, nausea and vomiting, headache, palpitation and other symptoms. Clenbuterol has never been approved for weight loss.

Phenylpropanolamine hydrochloride: an adrenergic drug that can increase fever and reduce appetite. Adverse reactions include hemorrhagic/ischemic stroke, myocardial infarction and hypertensive crisis. It was used to lose weight after 1980s and was withdrawn from the market by FDA in 2000.

Rimonaban: Cannabinoid receptor (CB 1) antagonist, which can suppress appetite and improve obesity-related insulin resistance. Since 2006, it has been listed in 56 countries, but it was not listed in the United States and China because of its nervous system side effects, such as seizures, depression, anxiety, insomnia, aggression and suicidal tendency, and withdrew from the global market in June 2008.

Diuretics: increase urination. It can cause the illusion of "weight loss" in a short time and cause electrolyte disorder.

Bisacodyl: It stimulates intestinal peristalsis by stimulating the mucosa of large intestine. It is a laxative. Causing abdominal cramps, long-term use will produce dependence and increase the risk of proctitis.

Metformin: The common adverse reactions of this drug are mainly gastrointestinal discomfort, including diarrhea, nausea and vomiting. Some experts believe that it may produce weight loss effect through these adverse reactions; It only has a mild weight loss effect on some specific groups, such as patients with type 2 diabetes and polycystic ovary syndrome, but in people without diabetes, obesity and insulin resistance, the weight loss effect of metformin is too weak and inaccurate, and it has not been approved by FDA as a weight loss drug.
