Risks of gastric bypass surgery

The statistic shows that 1 in 300 dies because of gastric bypass surgery. People suffering from morbid obesity may have other serious medical conditions that are related to or caused by being overweight. The higher your BMI is, the more likely it is that other medical problems will exist. Other medical problems may increase the risk of complications from gastric bypass surgery and the recovery period following gastric bypass surgery. Another risk factor is age, although this increases the need for surgery there is usually a higher risk. Any medical procedure involving humans and reactions to stress, trauma, drugs, and other causes, unpredictable negative results can and will occur. This surgery should be considered only after many attempts like diet control and exercise have failed. Diet and exercise will be required before and after this surgery.

Statistical data associated with the surgical procedure of gastric bypass include: failure of weight loss (about 10%), complication of surgery (10% – 15%), serious complication, life-threatening 2% – 3%), and even death (less than 1%). On the other hand, the risks associated with morbid obesity far outweigh the risks associated with surgery. For example, studies prove that the individual who has 100% of their ideal weight has a risk of mortality that is ten times that of thin counterparts (that is, the opportunity for an obese individual to die is ten times larger in Any year). There is no question that the potential benefits of surgery do not outweigh the risks.

Since the surgical procedure of gastric bypass results in some loss of absorbing function, the long-term consequences of deficiencies in potential nutrients should be recognized and adequate supervision should be performed, particularly with respect to vitamin B12, folate , And iron. Some patients may develop other gastrointestinal symptoms such as ‘discharge syndrome’ or gallstones.

Occasionally, patients may have postoperative mood changes or pre-surgical symptoms of depression that can not be improved by achieved weight loss. Thus, surveillance should include monitoring of nutrition indexes and inadequate modifications of any pre-operative disorder. The table below illustrates some of the complications that may occur subsequent to gastric bypass surgery:

Recommendation: Gastric bypass surgery is an option for carefully selected patients with severe clinical obesity (BMI 40 or 35 with co-morbid conditions) when less invasive methods of weight loss have failed and the patient is at high risk Of morbidity or mortality associated with obesity, Evidence of Category B.

After gastric bypass surgery, an occasional patient may have a complication regarding the staple line (?) Or the bag plug. For example, there may be leakage, puncture, or bleeding where some staples are dislodged by stretching too much from the bag.Other possible complications are formation of an ulcer or a restriction or lack of correct healing of the staple line. These kinds of problems can cause additional surgery needed. Although all precautions are taken to prevent them, complications occur from time to time.

For the first month, the patient may experience nausea and vomit until he or she is accustomed to the new small stomach.Patients then enjoy a sense of satisfaction with small amounts of food.

About one in twenty-five patients may need to be readmitted to the hospital due to vomiting. In the first few weeks after surgery, vomiting can cause swelling at the site of surgery. In addition, there is a possibility that vomiting may be caused by the formation of a restriction, scarring of the stomach pouch plug, or by obstruction of the pouch plug by a piece of poorly chewed food, a tablet , Or another foreign body. In most cases these complications can be corrected easily, without additional formal surgery.

Due to the limitation in food intake, supplemental vitamins should be taken. Vitamin supplementation will always be necessary to minimize the risk of anemia, weakness, muscle incoordination, and clinical depression. During the first few weeks following surgery, a liquid or a chewable vitamin is advised. Then any good multivitamin preparation containing adequate amounts of vitamins and minerals complex B.

There is some evidence that babies may be born with congenital abnormalities when there is rapid weight loss during pregnancy. Therefore, pregnancy should be avoided until the weight has stabilized. Once the weight has stabilized, there are no contraindications to pregnancy.
