Losing weight is not only for being slim, but for obese people, reducing weight can also reduce the burden on the heart, which is conducive to lowering blood pressure, regulating the concentration of triglycerides, glucose and insulin in the blood, and reducing fatty liver, hypertension, dyslipidemia, diabetes and other diseases. recovery has a considerable effect. Therefore, after trying diet, exercise and other measures to lose weight effectively, many people turn their attention to diet pills, but they are full of doubts about it: “Can I use diet pills?”, “Are there any adverse reactions to diet pills?”, “What should be paid attention to when using it?”
Question: How do diet pills work?
At present, the prescription weight loss drugs approved by the state include orlistat (trade name: Xenical) and sibutramine (trade name: Qumei, Aoquqing, Kexiu, Quting). The weight loss effects of these two weight loss drugs are different. Orlistat is a gastrointestinal lipase inhibitor that reduces the amount of fat absorbed from food in the human gastrointestinal tract to control caloric intake and reduce weight. Sibutramine is a central appetite suppressant, which induces the brain to issue “full” or “don’t want to eat” instructions to control diet.
Second question: Are there any adverse reactions to diet pills?
All drugs have certain adverse reactions, so do not take them blindly. Among them, orlistat specifically acts on the stomach and intestines and hardly enters the blood, so the adverse reactions are small, but there are still gastrointestinal discomfort such as flatulence, abdominal pain, and oily stool, and it can also affect fat-soluble vitamins, potassium etc. absorption. Therefore, during the use of orlistat, attention should be paid to the supplementation of vitamins and minerals, and it is not suitable for long-term application. In addition to causing dry mouth, blurred vision, dizziness, sweating, sleep disturbance and migraine, sibutramine can also cause cardiovascular system abnormalities such as palpitations, tachycardia, arrhythmias, and hypertension. Also note that diet pills containing ephedra have been banned in the United States because they can stress the heart and can lead to death. “my country has banned the production and sale of weight loss drugs containing fenfluramine hydrochloride since January 7 this year.” Orlistat and sibutramine are both prescription drugs, which must be purchased with a doctor’s prescription and taken according to the doctor’s order. In order to reduce or avoid adverse reactions, generally start with a small dose and gradually increase the dose until the most appropriate dose, so as to achieve both effective weight loss and minimize adverse reactions.
Three questions: Who can use diet pills?
When using weight-loss drugs, you must strictly grasp the indications, understand whether you need weight-loss drugs, and what kind of drugs are suitable for use. It is best to do it under the guidance of a specialist. Generally speaking, there are the following situations can take diet pills. First, learn to calculate the standard weight [height (cm)-100) × 0.9]. A person is truly obese when his actual weight is more than 20% higher than the standard weight. Otherwise, don’t over-diet, let alone take medicine to lose weight. Only moderate-to-severe obese people who are over 30% overweight should consider taking diet pills while paying attention to diet regulation and exercise. Second, obese people who have undergone strict diet control and exercise treatment, if they start to lose weight, but due to various reasons, they will gain weight after half a year. At this time, it is more appropriate to take weight loss drugs in conjunction with treatment. For those who are difficult to control with diet therapy, such as some obese people with peptic ulcer, diet pills can also be added to consolidate the weight loss effect. However, people who have undergone gastrointestinal surgery or patients with biliary tract disease are not suitable for orlistat weight loss.
Question 4: What should I pay attention to when taking diet pills?
When taking diet pills, attention should be paid to the balance between weight loss effect and adverse reactions, and the pros and cons should be weighed when choosing drug therapy to avoid long-term medication. Specifically, the first choice of medicines should be under the guidance of a professional doctor. Doctors will decide whether to take medication or what kind of regular weight loss drugs to choose according to the patient’s condition (such as cardiovascular function, presence or absence of digestive system diseases, mental status, etc.) to help him avoid the harm of adverse drug reactions. Second, treat specific people differently. Teenagers to lose weight need to be carefully screened before taking medication, and strict monitoring is required to avoid nutritional deficiencies affecting normal growth and development. Pregnant and breastfeeding women are prohibited from using diet pills that suppress appetite to prevent fetal development and child growth. Obese people with heart disease, high blood pressure or fatty liver should be careful when choosing diet pills. Also look out for drug interactions. Because most appetite suppressants can increase blood pressure and affect the effect of antihypertensive drugs, blood pressure should be monitored weekly during the first 4 to 6 weeks of using weight loss drugs. For patients who have used Youjiangning, selegiline, griseofulvin, isoniazid, etc. within 2 weeks, it is forbidden to use appetite suppressants in combination to prevent the occurrence of hypertensive crisis. Third, pay attention to drug monitoring. Body weight should be monitored before and during taking the medicine. It is better if indicators such as blood glucose and blood lipids can be monitored at the same time. Help adjust the dose of the drug based on the monitoring results. When to increase the dose or stop the drug, it should be carried out under the guidance of a doctor.
