Gastric bypass surgery is a great technique to fight obesity, as well as diseases related to obesity. This technique has been widely used for many years and has very promising results during the following years after the surgery.


How is the procedure?

The gastric bypass creates, using staples, a new small reservoir (a stomach “pouch”) of approximately 75 ccs. This pre-stomach is completely closed and separated from the rest of the stomach. The small pre-stomach reduces your appetite and you feel fuller quickly.


The benefits of a gastric bypass surgery

On average, patients lose 70 to 80% of their maximum excess weight 5 years after gastric bypass surgery. Gastric bypass surgery also is very beneficial for a number of diseases linked to obesity. For instance, 3 years after the bypass, 90% of patients improve their diabetes, and on average 80% of patients will no longer need to take diabetes medication after a certain period. There is an immediate reduction (or even disappearance) of diabetes in non-insulin-dependent and - although less important - lipid balance, and arterial hypertension.


Post-operative care

Gastric bypass surgery is performed under general anesthesia and lasts normally between an hour to two hours depending on the patient’s physiology. The post-operative care would be:

· A hospital stay of a minimum of 2 days. 

· The patient can start drinking the day after the operation.

· The wounds are covered with special dressings that allow the patient to take a shower. The doctor will remove them during the next check-up. 

· After two weeks, the patient can begin the postoperative exercise program. 

After a bypass gastric surgery, it is important to have regular postoperative follow-ups with a surgeon and a nutritionist. The reason for this is that the patient will face a great weight loss, therefore, it is obligatory to check with a nutritionist or dietitian every few months. You should note that the first year is the year of the greatest weight loss and that there would be vitamin and mineral deficiencies including vitamin B6, B9 B12, D, zinc, and iron.


In the practice of gastric bypass, there are two goals, the first goal is that the person craves less food and the second goal is that the food eaten is less absorbed by the body. In this method, two parts of the gastrointestinal tract are operated on, which include shrinking the stomach and shortening the small intestine.

Usually, people who are sweets or sweet lover and are very interested in sweets and ice cream are more suitable for this operation because due to the type of action and the absorption disorder created, the calories received from their sweets will be very low.

The risk of mortality in gastric bypass surgery is about 0.5%. The risk of this operation is the same as gallbladder surgery, and when you perform this operation, it seems that you have accepted the risk of gallbladder surgery. Due to the fact that this operation is performed laparoscopically and the patient's abdomen does not open, the risk of death and infection is very, very low and close to zero.

You will be hospitalized for a total of 3 days, and if you wish, you will be admitted to the intensive care unit for one day, after which you can go home and return to work after a week.

6 months after gastric bypass surgery or other obesity surgeries, you will lose 80% of your weight and will continue to lose weight for a year and a half after surgery. If weight loss stops, size reduction occurs, but it is recommended that patients undergoing gastric bypass be sure to include mobility and walking in their daily routine and drink plenty of water to speed up the weight loss process.
