In the gastric bypass surgery, surgical changes are made in the stomach and the digestive system that limits how much food you can eat and how many nutrients you absorb, leading to weight loss. Patients typically lose more than 50% of their excess weight after Bariatric surgery. Obesity-related diseases markedly improve after gastric bypass surgery, reducing cardiovascular risk and improving life expectancy.
Positives
Not only do patients lose weight and keep it off, now there are convincing data that many patients are cured of type 2 diabetes. In fact, the procedure may pay for itself within a few years by reducing medical costs due to obesity-related illness.
While it may sound appealing, gastric bypass isn't for everyone. Like any major procedure, it has significant health risks and side effects. In addition, the long-term success of gastric bypass surgery depends on your ability to make permanent changes in your lifestyle. When you want to be considered for gastric bypass surgery, you must undergo a thorough evaluation to determine if it's suitable for your situation.
Negatives
Apart from the immediate risks of complications associated with a major surgery, you put yourself at risk of a clutch of problems: osteoporosis, anemia and other nutritional deficiencies, bowel obstruction, gallstones, hernia, ulcers, stomach perforation, and/or gastric dumping syndrome, characterized by the frequent diarrhea and vomiting.
And then there's still more - depression, alcoholism and suicide.
Some of the complications of gastric bypass are:
1. Bleeding
Unlike gastric sleeve plication and gastric band, bleeding complications occur in fewer than 4% of patients. Postoperative bleeding can be from mesenteric or omental vessels within the peritoneal cavity or from staple line.
2. Anastomotic leak
Anastomotic leak is a dreaded complication of gastric bypass and carries a mortality rate of up to 30% when it occurs. The incidence after gastric bypass ranges from 0% to 4.4%.Leakage from the gastrojejunal anastomosis can be contained or can result in diffuse peritonitis. Technical failures of the anastomosis manifest in the early postoperative period with rapid clinical deterioration, but most leaks occur around 5 days after surgery and result from perforation of an ischemic area at the anastomosis.
3. Wound infection
Wound infection after gastric bypass occurs in fewer than 5% of cases in most series. And it can be easily managed with a course of antibiotics.
4. Thromboembolism
Obesity is a risk factor for venous thromboembolism in general surgery patients. The higher the BMI, the higher the risk of venous thromboembolism in patients undergoing abdominal operations, even with low-dose heparin prophylaxis and obesity is an independent predictor of recurrent venous thromboembolism.
