What Is Gastric Sleeve Surgery?
Gastric sleeve surgery, also known as sleeve gastrectomy, is a popular weight loss procedure that involves removing about 80% of the stomach. The remaining portion is shaped into a narrow tube or "sleeve," which limits the amount of food you can eat and helps you feel full more quickly.
This surgery is typically recommended for individuals who are 100 pounds or more over their ideal weight or have a BMI of 40 or higher, or 35+ with related health conditions.
While effective, it’s important to fully understand the risks and side effects before making your decision.
Risks of Gastric Sleeve Surgery
Like any major surgery, gastric sleeve surgery comes with risks. These may occur immediately after surgery or develop over time. Common risks include:
- Excessive bleeding
- Blood clots
- Infection
- Adverse reaction to anesthesia
- Breathing difficulties
- Leakage from the staple line (where the stomach was cut and sealed)
Long-Term Complications of Gastric Sleeve Surgery
Beyond the initial risks, patients should be aware of long-term complications such as:
- Gastroesophageal reflux disease (GERD)
- Nutritional deficiencies (e.g., vitamin B12, iron, calcium)
- Chronic nausea or vomiting
- Gastrointestinal obstruction or hernias
- Hypoglycemia (low blood sugar)
These complications can often be managed with lifestyle adjustments, vitamin supplementation, and routine follow-ups.
Side Effects After Gastric Sleeve Surgery
In the months following surgery, patients often experience rapid weight loss—which can lead to temporary side effects, including:
- Fatigue
- Cold sensitivity
- Dry skin
- Hair thinning or hair loss
- Mood changes or irritability
- Muscle aches
Your diet will also be restricted to liquids and pureed foods for the first few weeks. Over time, you will transition back to soft and eventually regular foods. Vitamin supplementation is mandatory for life, including:
- Daily multivitamins
- Calcium supplements
- Monthly B12 injections
