Are weight loss pills effective?

Weight loss pills have been used by many people who have lost weight before. Many people want to become thinner through the method of taking weight loss pills, but it is precisely because of the good market that many weight loss pills are produced unqualifiedly, and the effectiveness of weight loss pills is not good either. Many women have been injured by weight loss pills, but still, many people want to know if weight loss pills are effective and want to take weight loss pills to lose weight.

The weight loss pills on the market are really a mixture of the good and the bad, and even some weight loss pills have been banned. However, many people believe that taking weight loss pills is a convenient way to lose weight, but are weight loss pills effective? Through the following introduction, everyone should have an answer.

Weight loss drugs can be generally divided into four types according to their mechanism of action.

1. Appetite suppressants: Mainly amphetamine-like drugs. Medical research shows that human appetite is regulated by the satiety center in the ventromedial nucleus of the hypothalamus and the feeding center in the ventrolateral nucleus together. The action of amphetamine-like drugs is: by exciting the satiety center, producing anorexia reaction, the appetite decreases after taking the medicine, and it is easy to accept dietary control. At the same time, due to its excitatory effect, it reduces sleep, increases consumption, and leads to weight loss. There are many types of such drugs, but they are all less used due to the side effects of central excitation, such as insomnia, restlessness, palpitations, increased blood pressure, and addiction. Only because of the small side effects and reliable effects, they are more used in weight loss treatment.

2. Gastrointestinal lipase inhibitors: Represented by orlistat, which is the only drug approved for weight loss in the country. By forming a covalent bond with the active serine site of the gastric lipase and pancreatic lipase in the lumen of the stomach and small intestine, the enzyme is inactivated. The inactivated enzyme cannot hydrolyze the fat in the food (mainly triglycerides) into absorbable free fatty acids and monoglycerides. The undigested triglycerides cannot be absorbed by the body, thereby reducing calorie intake and controlling weight.

3. Hormonal drugs (also known as metabolic stimulants): Mainly represented by thyroxine, which can increase the metabolism of the body, increase the decomposition and consumption of fat, and thus reduce weight. However, when this type of drug is used, it can often have adverse effects on the cardiovascular system if the dosage exceeds the normal physiological dose. It needs to be used with caution under the guidance of a doctor.

4. Biguanide hypoglycemic drugs: The pharmacological action is to increase the anaerobic glycolysis of muscle tissue, increase the utilization of glucose, and reduce its absorption in the intestines, thereby lowering blood sugar. Such drugs often cause patients to have anorexia and weight loss when treating diabetes. By utilizing this side effect, it can be used for weight loss treatment. Biguanide hypoglycemic drugs have no effect on the blood sugar of normal people. Therefore, obese patients with diabetes can also take them.

4. Adjusting the acid-base balance of the human body: The pH value of the body's body fluids is 7.35-7.45. Due to irregular lifestyle, imbalanced diet, and environmental changes, among other things, modern people have a change in the acid-base balance of the body, which is manifested as obesity, insomnia, freckles, constipation, and even diseases. 100% of gout, hypertension, cancer, and hyperlipidemia patients are acidic constitution. Such drugs adjust the acid-base balance of the body, restore cell vitality, and thus the normal functioning of various body functions, the excretion of waste, and the natural recovery of the body shape to achieve the goal of weight loss, and the diseases caused by this will also disappear.
