Lap-Band Side Effects: What to Expect & Potential Risks

The Lap-Band is an adjustable silicon belt that is fitted around the stomach to restrict its size and induce weight loss. While the procedure is usually successful, there are mild and serious side effects associated with the Lap-Band. Gastrointestinal disturbances include nausea, vomiting, constipation and diarrhea. Some patients may experience poor nutrition or protein deficiency. In rare instances, the band can become displaced or begin to deteriorate inside the body.

Nausea and Vomiting

• Common side effects of the Lap-Band are nausea and vomiting. These occur while the body attempts to adjust to the altered stomach.

Diarrhea and Constipation

• Other side effects patients may experience while adjusting to the Lap-Band are diarrhea and constipation.

Protein Deficiency

• A serious side effect of the Lap-Band is protein deficiency, which leads to fatigue, weakness and hair loss. Patients should take extra measures to consume foods that are high in protein.

Gastric Perforation

• A serious possible side effect of Lap-Band surgery is gastric perforation, which is a rip in the stomach tissue. This occurs in less than 1 percent of surgery patients but requires immediate corrective surgery.

Erosion or Displacement

• A rare side effect of the Lap-Band is the displacement or erosion of the device. This is likely to occur if the patient does not follow the strict post-operation diet guidelines.
