What Are the Negative Side Effects of Gastric Sleeve Surgery?
Gastric sleeve surgery (sleeve gastrectomy) is one of the most effective surgical options for weight loss, especially for individuals struggling with obesity. It helps reduce hunger, limit food intake, and promote sustainable weight loss.
However, like all medical procedures, it’s important to understand the potential risks and side effects before making a decision. Here’s what you need to know.
⚠️ 1. Surgical Complications
As with any surgery, there are risks associated with anesthesia and the procedure itself, including:
- Bleeding
- Infection at the incision sites
- Blood clots (DVT or pulmonary embolism)
- Reactions to anesthesia
- Staple line leakage (rare but serious)
✅ Choosing an experienced surgeon and following pre-operative instructions can greatly reduce these risks.
🧪 2. Nutritional Deficiencies
Because the stomach is smaller and digestion is altered, patients may absorb fewer nutrients than before.
Deficiencies can include:
- Vitamin B12
- Iron
- Calcium
- Folate and fat-soluble vitamins (A, D, E, K)
✅ Daily multivitamins and regular blood work are essential after surgery.
🔥 3. Acid Reflux or Heartburn
Some patients may develop or experience worsened gastroesophageal reflux disease (GERD) due to the reduced size and shape of the stomach.
Symptoms may include:
- Burning sensation in the chest
- Regurgitation or sour taste
- Difficulty sleeping after meals
✅ Your doctor may recommend medications or dietary changes to manage symptoms.
🤢 4. Nausea and Vomiting
Eating too fast, too much, or the wrong type of food can lead to:
- Nausea or bloating
- Vomiting after meals
- Dumping syndrome in rare cases
✅ Following the post-op diet strictly and eating slowly can help prevent these symptoms.
💎 5. Gallstones
Rapid weight loss increases the risk of gallstone formation. These can cause:
- Sharp abdominal pain
- Nausea
- Possible need for gallbladder removal
✅ Your doctor may recommend preventive medication or monitor for symptoms after surgery.
🏥 6. Need for Additional Surgery
While most patients are successful with gastric sleeve, some may require:
- Revision surgery due to inadequate weight loss
- Surgery to manage complications like leaks or strictures
- Body contouring procedures to remove excess skin
✅ A long-term follow-up plan can reduce the need for additional surgeries.
