It is not recommended to use drugs that suppress appetite to lose weight quickly by yourself. Such drugs may have many health risks and it is difficult to achieve long-term stable and healthy weight loss. Some appetite suppressants may cause nausea, vomiting, insomnia, palpitations, dry mouth, constipation and other adverse reactions. Long-term use may also lead to endocrine disorders, addiction and other problems. Healthy weight loss should be achieved through reasonable diet control (reduce the intake of high-calorie, high-fat, and high-sugar foods, increase vegetables, fruits, whole grains and other foods rich in dietary fiber) and moderate regular exercise. Generally, weight loss of 0.5-1 kg per week is more appropriate. If there is a need for weight loss, it is recommended to carry out scientific planning and management under the guidance of a doctor or a professional dietitian, rather than relying on drugs.
