Gastric bypass in Barranquilla, Colombia

What is gastric bypass?

It is one of the most widely performed and studied bariatric surgeries. In the most common technique, Roux-en-Y gastric bypass, a small egg-sized stomach pouch is created and connected directly to part of the small intestine. Food bypasses most of the stomach and the first section of the intestine. It is done laparoscopically.

How does it help with weight loss and diabetes?

You feel full with small portions, fewer calories are absorbed and gut hormones that regulate hunger and insulin change. That is why it is especially effective for people with type 2 diabetes, which often improves or goes into remission. Most weight loss happens during the first year and a half.

Bypass or gastric sleeve?

Bypass is often preferred when there is hard-to-control type 2 diabetes or significant acid reflux, since a sleeve can worsen reflux. The sleeve is a somewhat simpler surgery that does not reroute the intestine. The surgeon recommends the technique based on your conditions, history and goals.

What care is needed afterward?

Lifelong supplements, especially vitamin B12, iron, calcium, vitamin D and a multivitamin, with regular lab checks. Avoid anti-inflammatory drugs such as ibuprofen and smoking, which raise the risk of ulcers. Limit sugars to prevent dumping syndrome, which causes dizziness, sweating and diarrhea after eating. Keep in mind that alcohol takes effect faster and more strongly.

What are the risks?

Like any surgery, it can have complications, including bleeding, leaks at the connections, blood clots, ulcers, bowel obstruction or internal hernias, which can appear even years later. If you have severe, persistent abdominal pain after surgery, seek care immediately. Choosing an experienced team greatly reduces these risks.
