Gastric Bypass Surgery: Long Term Outcomes

People prefer bariatric surgery because it is safer and less invasive. Gastric bypass is the most preferred, and then there’s sleeve gastrectomy, gastric bands, Roux-en-Y, and biliopancreatic diversion. Among these, Roux-en-Y is the most common surgical procedure. In this procedure, the surgeon makes a small pouch above the stomach, and no other part of the stomach will receive food except the pouch. This significantly limits what you can consume. The surgeon connects the pouch to the small intestine, at a part below where the main stomach attaches to the small intestine. Therefore, food bypasses a large part of the small intestine, limiting the absorption of calories and nutrients.

Here are the outcomes of this procedure:

• Weight loss in the long-term- For those with about 100 lbs. to lose and with a BMI above 40, gastric bypass is their ideal option to regain health. Two years after the procedure, a patient loses 60 percent of their excess weight.

• Remission of other diseases-two to five years post-operative, people experience a remission oftype 2 diabetes and cardiovascular disease. There’s also symptom relief from other conditions such as depression, sleep apnea, joint, and back pain.

After Gastric bypass surgery, some patients may experience:

• Deficiency of vitamins and minerals (30 percent)

• Dumping syndrome – nausea, weakness, or vomiting because of the fastmovement of food along the gut, especially after the consumption of carbohydrates or sweets (50 percent).

• Gallstones due to fast weight loss (20%)

• Stomach stenosis – This is the narrowing of the opening found at the point where the stomach links to the intestine (below 5 percent).

• Hernias ( below 5 percent)

• Bowel obstruction (3 percent)

• Staple line leakage (3%)

• Pulmonary embolism (2%)

However, when patients stick to the recommended diet, consume vitamin supplements, and adhere to follow-up visits, the overall rate of these complications following gastric bypass is below 6%. Those intending to undergo this surgery will find that its advantages outweigh the possible risks.
