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.
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.
