Potential Complications
Rare and short-term risks of bariatric surgery include:
- Infection
- Excessive bleeding
- Anesthesia reactions
- Breathing problems
- Blood clots
- Gastrointestinal leaks
- Dehydration
- Moderate swelling, bruising, or pain
- Weakness or fatigue
- Nutritional deficiencies
- Temporary hair loss
In most cases, side effects are uncomfortable or unpleasant but not serious enough to endanger patients. However, if any of these symptoms become severe, patients should alert their doctor immediately.
Some of the more common long-term risks include:
- Indigestion and nausea: These concerns can usually be treated with dietary changes. If indigestion persists, medication such as antacids may be indicated. Patients might also experience an intolerance to certain foods or suffer from nausea and vomiting.
- Dumping syndrome: Dumping syndrome occurs when the stomach is rapidly emptied of food (especially sugar). Patients may experience weakness, dizziness, flushing and warmth, nausea, and heart palpitations immediately or shortly after eating. This complication can be managed by sticking with the prescribed bariatric diet.
- Band problems: Band problems for patients who have had LAP-Band surgery may include band slippage, band leakage, band intolerance, and band erosion. Either another bariatric surgery or band removal is necessary to fix these issues.
- Changes in bowel function: Bowel function changes after bariatric surgery can include loose stools or diarrhea, constipation, and gurgling noises. Most of these ailments can be managed with dietary changes.
Other complications include gallstones, hernias, food entrapment, pouch complications, hair loss, and malnutrition. Hair loss and malnutrition can be minimized or avoided by eating a recommended bariatric diet, as well as taking any prescribed nutritional supplements.
