Obesity Surgeries (Sleeve Gastrectomy and Gastric Bypass): Your Path to a Healthier Life with Professor Dr. Mohamed Arafat

Obesity surgeries are among the most effective medical solutions for losing excess weight and improving quality of life. These include sleeve gastrectomy and gastric bypass, which help patients achieve safe and long-lasting weight loss.
Professor Dr. Mohamed Arafat, Professor of General and Laparoscopic Surgery at Al-Azhar University and Consultant of Advanced Laparoscopic and Bariatric Surgery, explains that the goal of these procedures is not only to reduce weight but also to prevent chronic diseases such as diabetes, hypertension, and sleep apnea.

What Are Obesity Surgeries?

Dr. Mohamed Arafat emphasizes that obesity surgeries are performed for patients suffering from severe obesity who have not succeeded in losing weight through traditional methods such as diet and exercise. These surgeries work by reducing stomach size or changing the food pathway to limit calorie absorption.

Sleeve Gastrectomy

Dr. Mohamed Arafat explains that the sleeve gastrectomy involves removing about 70–80% of the stomach, which reduces food intake and creates a faster feeling of fullness.
He notes that sleeve surgery helps improve overall health, as it reduces the risk of type 2 diabetes and improves blood pressure and cholesterol levels significantly after the operation.

Gastric Bypass

Professor Dr. Mohamed Arafat confirms that gastric bypass surgery is one of the most effective procedures for weight loss, as it involves reducing stomach size and bypassing part of the small intestine to decrease fat and calorie absorption.
He stresses that this operation is particularly suitable for patients with type 2 diabetes, as it greatly improves blood sugar control and may even eliminate the need for medications.

The Difference Between Sleeve and Bypass

Dr. Mohamed Arafat clarifies that the difference between the two surgeries lies in their mechanism and long-term outcomes; sleeve surgery reduces stomach size only, while gastric bypass changes the digestive route and decreases nutrient absorption.
He warns that the choice of procedure should be based on each patient’s medical condition, history, and obesity level — determined after thorough examination and consultation.

Post-Surgery Recommendations

Professor Dr. Mohamed Arafat stresses the importance of regular follow-ups after surgery and adopting a healthy diet to maintain results. He also emphasizes the need to take vitamin supplements and engage in regular physical activity to avoid complications.
