(3) Suggestions
Drug treatment of obesity is an auxiliary treatment of diet, exercise and behavior intervention. In order to achieve the maximum curative effect, drug therapy must be based on lifestyle intervention, otherwise the weight loss effect of drugs is limited.
It is suggested to use recognized diet pills to improve complications and increase patients' dependence on behavior changes. Non-specialists should not choose non-indication drugs.
It is necessary to evaluate the safety and effectiveness of diet pills regularly. If the diet pills are effective (weight loss > 5% within 3 months) and safe, it is recommended to continue using them. If it is ineffective (weight loss < 5% within 3 months) or there are safety and tolerance problems at any time, stop taking medicine, change medicine or choose other treatment methods immediately.
