The principles of weight loss drugs mainly include the following:
- Appetite suppression: Acting on the central nervous system to reduce appetite, causing people to eat less.
- Increasing energy expenditure: Boosting metabolism to increase the body's energy consumption, such as enhancing fat oxidation.
- Inhibiting fat absorption: Preventing the intestinal absorption of fat, causing the ingested fat to be excreted with feces.
However, weight loss drugs may bring various harms: - Cardiovascular problems: May lead to arrhythmias, elevated blood pressure, palpitations, and other adverse reactions in the cardiovascular system.
- Gastrointestinal problems: Commonly include nausea, vomiting, diarrhea, abdominal pain, indigestion, etc.
- Mental and neurological problems: Such as anxiety, insomnia, depression, dizziness, headache, etc.
- Liver and kidney function impairment: Some weight loss drugs may cause damage to the liver and kidneys, affecting their normal functions.
- Malnutrition: Weight loss drugs that suppress appetite or affect nutrient absorption may lead to the body lacking essential nutrients and affecting health.
- Endocrine disorders: Interfering with the body's hormone balance, resulting in menstrual disorders, abnormal hormone levels, etc.
In conclusion, the use of weight loss drugs should be under the guidance of a doctor, and one should not rely solely on weight loss drugs for weight loss. A healthy diet and moderate exercise are safe and effective ways to lose weight.
