There are actually many kinds of weight loss methods, healthy and unhealthy, effective and ineffective, and each has its own advantages and disadvantages, it is difficult to say which is the best. Weight loss pills and weight loss surgery are two types of weight loss, whether for the population or the effect are not the same, basically not comparable. The two types of weight loss surgery and pills are both medical methods of mandatory intervention to achieve the purpose of weight loss. 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, eating than the normal people to pay more attention to a little, 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 those who have complications caused by obesity, such as type 2 diabetes caused by obesity can be well controlled through weight loss surgery. 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 using 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. The 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 complications. And weight loss should be carried out according to their actual situation, not too blindly, otherwise it is easy to play the opposite effect.
