There are many ways to lose weight, some healthy and some unhealthy, some effective and some not, and each has its own advantages and disadvantages, it is difficult to say which is the best. Some people have recently put together two weight loss methods, drug weight loss and weight loss surgery, to discuss which is better, but in fact this is completely unnecessary. The two types of weight loss are not the same whether it is for the population or the effect, basically there is no comparison. Although both medication and weight loss surgery are medical methods to achieve weight loss by mandatory intervention on the human body. But the principle of action and effect is obviously different, take their disadvantages, the disadvantage of drug weight loss is that there are side effects, easy to rebound, the effect is limited. While weight loss surgery does not have these disadvantages, but after weight loss surgery on eating habits and other aspects of the requirements will be more stringent, when eating to pay more attention than normal people, although not easy to regain weight, but also will not have a good appetite before. In addition, there is basically no overlap between the two methods of adapting to the population. The mechanism of action of drugs for weight loss is through the reaction of drugs and some hormones in the body, causing a decrease in appetite, accelerated metabolism or malabsorption, and will produce different degrees of side effects. And the body will also appear drug resistance, after a period of time the same kind of drugs will be useless, because of this, drug weight loss is only destined to become a temporary means of weight loss, or through drug weight loss first to reduce weight a little, and then use other safer and more effective methods to achieve the purpose of long-term weight loss. Weight loss surgery is mainly for those who are morbidly obese after using various weight loss methods are ineffective, or for those who have complications caused by obesity, such as type 2 diabetes caused by obesity can be well controlled through weight loss surgery. And when obesity has seriously endangered the patient’s life, weight loss surgery has a high probability of saving the patient’s life, which cannot be achieved by other weight loss methods, not to mention the drug weight loss which has a lot of side effects. It can be said that general weight loss methods (exercise, medicine, dieting, etc.) are only in the prevention of more serious obesity or to achieve the role of reducing the degree of obesity, while weight loss surgery is to save obesity, when the dieter through these methods still can not effectively control obesity, resulting in obesity becomes serious serious, or the emergence of obesity associated with the disease, which will consider the use of weight loss surgery. The legitimate weight loss surgery team has requirements for the surgery, they have to guarantee the safety of the patient and do not do it whenever they want. So it doesn’t really make sense to use weight loss pills to compare with weight loss surgery, this method of weight loss is not on the same level. Drug weight loss can only exist as a temporary solution, while weight loss surgery is the treatment for those who are morbidly obese and already suffer from obesity concomitant disorders. For patients with a high BMI weight base, surgical weight loss will be more effective than weight loss pills.
