Possible Complications After Sleeve Gastrectomy

Sleeve Gastrectomy Complications

Although sleeve gastrectomy is considered safe for most patients, some sleeve gastrectomy complications may occur, including:

  • Gastroesophageal reflux disease (GERD)
  • Staple line leak
  • Nutritional deficiencies
  • Blood clots
  • Gallstones
  • Gastric stenosis
  • Dumping syndrome

Sleeve Gastrectomy Long-Term Complications

Long-term issues may include chronic vitamin deficiencies, persistent acid reflux, and the need for additional procedures in rare cases. However, most of these complications can be avoided with proper care and follow-up.

Sleeve Gastrectomy Leak

Staple Line Leak

A staple line leak is a rare but serious complication that can occur after surgery. It happens when the sutured part of the stomach doesn't heal properly, leading to leakage of gastric contents.

Sleeve Gastrectomy Prevention

To reduce the risk:

  • Choose an experienced surgeon
  • Avoid eating too soon after surgery
  • Follow dietary guidelines carefully
  • Avoid excessive physical strain during recovery

Reflux After Sleeve Gastrectomy

GERD After Sleeve Gastrectomy

One of the more common long-term complications after sleeve gastrectomy is the development of gastroesophageal reflux disease (GERD). This can cause heartburn, chest pain, and discomfort, especially after eating.

Sleeve Gastrectomy Prevention

To prevent reflux after sleeve gastrectomy:

  • Avoid eating right before sleeping
  • Eat small, frequent meals
  • Avoid acidic drinks
  • Maintain a healthy post sleeve gastrectomy diet focused on soft, protein-rich foods

Nutritional Deficiencies After Sleeve Gastrectomy

Sleeve Gastrectomy Nutritional Deficiencies

Because the stomach size is significantly reduced, patients may experience nutritional deficiencies after sleeve gastrectomy, such as low levels of:

  • Vitamin B12
  • Vitamin D
  • Folate
  • Iron and calcium

Sleeve Gastrectomy Prevention

To avoid vitamin deficiencies after sleeve gastrectomy, it's crucial to:

  • Take daily vitamin supplements after sleeve gastrectomy
  • Follow a nutrient-dense diet
  • Attend regular follow-up appointments with your nutritionist

At Safemedigo, we provide personalized nutrition plans and recommended supplements tailored to your body’s needs for long-term health.

Blood Clots After Sleeve Gastrectomy

Sleeve Gastrectomy Blood Clots

One of the known short-term complications after sleeve gastrectomy is the risk of blood clots, especially deep vein thrombosis (DVT), which can occur due to reduced mobility after surgery.

Deep Vein Thrombosis Sleeve Gastrectomy

To prevent blood clots after sleeve gastrectomy:

  • Wear compression socks before and after surgery
  • Start light movement as soon as possible
  • Follow your doctor’s instructions on anticoagulant medications

Gallstones After Sleeve Gastrectomy

Sleeve Gastrectomy Gallstones

Rapid weight loss following sleeve gastrectomy increases the risk of gallstones after sleeve gastrectomy due to changes in bile composition.

Sleeve Gastrectomy Prevention

To prevent gallstone formation:

  • Follow a balanced diet rich in fiber
  • Consider preventive medications in the first few months
  • Stay well-hydrated and maintain steady weight loss

Obstruction or Stenosis After Sleeve Gastrectomy

Gastric Stenosis After Sleeve

Gastric stenosis or obstruction can occur if the stomach narrows at the surgical site, causing nausea, difficulty swallowing, and abdominal pain.

Sleeve Gastrectomy Obstruction

To prevent gastric stenosis after sleeve gastrectomy:

  • Chew food thoroughly
  • Avoid fibrous or hard-to-digest foods
  • Follow your doctor's dietary instructions

Dumping Syndrome After Sleeve Gastrectomy

Sleeve Gastrectomy Dumping Syndrome

While more common after gastric bypass, dumping syndrome after sleeve gastrectomy can still occur, especially after consuming high-sugar or high-fat foods. Symptoms include:

  • Dizziness
  • Sweating
  • Nausea
  • Diarrhea

Sleeve Gastrectomy Prevention

To avoid dumping syndrome:

  • Avoid sugary foods
  • Eat small, balanced meals throughout the day
  • Stay hydrated and chew your food well
