Obesity will not only cause a variety of physiological concomitant diseases, but often also bring some psychological barriers. People who are excessively obese are easily treated by others with different eyes. Coupled with the decline in physical fitness caused by obesity and the blow brought by frequent weight loss failures, obese people can easily become self-absorbed or even depressed, or even lose confidence in weight loss. After the surgery, the patient needs to cooperate with the health manager’s guidance on diet and exercise. If the patient does not cooperate or even does not cooperate at all because of the heart obstacle, it is likely that complications of the surgery will occur. It is also in consideration of this situation that it is stipulated in the “Chinese Guidelines for the Surgical Treatment of Obesity (2007)” that patients with alcohol or drug dependence, severe mental and intellectual disorders are not suitable for weight loss surgery through weight reduction. For those patients with psychological disorders, the psychological aspect of the treatment should be carried out first before the need for weight loss surgery, to ensure that they are voluntarily accepting such surgery and can cooperate with the post-operative recovery guidance. And there should also be a psychologist to follow up during this whole process to mediate in time when they have a psychological disorder so that they can recover smoothly. Weight loss surgery is also a kind of surgery to cure the disease, to take the patient’s safety as a prerequisite, before doing the surgery also have to weigh the pros and cons, to make sure that the patient can get enough benefit from the surgery, for the patient to be responsible, so that is why the regular medical institutions will not give those patients who do not fit the conditions of surgery to do surgery.
