Sleeve Gastrectomy

Sleeve Gastrectomy surgery has become the world's first in recent times for its safety and ease and no events change in the internal anatomy or the function of the digestive system.


Also referred to as ‘Gastric Sleeve’, Sleeve gastrectomy’s main idea is to create a small stomach pouch shaped like a narrow sleeve and remove the remaining bigger portion; which produces the hormone responsible for appetite, so after the sleeve procedure hunger is greatly diminished. Favourably, all the functions of the stomach remain intact, only its volume is reduced. The Sleeve operation has become the best obesity surgery in the world recently because of its safety and ease as well as no change in the internal anatomy or digestive function.

How does sleeve gastrectomy work?

Gastric sleeve belongs to a group of obesity surgeries that reduce the size of the stomach (restrictive bariatric surgeries), and hence reduce the capacity of food, which leads to a rapid sense of satiety with the least amount of food possible. The resected stomach contains the cells that secrete the hormone responsible for hunger. With the eradication of this expanding part, the hormone secretion is reduced and hunger is also reduced.


What to expect after Sleeve Operation?

Following surgery, you will not be able to eat as much food as you can now and you may put off a compelling amount of weight, which would enhance your overall health and your quality of life, and thus, increasing your life expectancy. Other conditions that relate to or are affected by obesity may be mitigated as well, such as diabetes mellitus, hypertension and sleep-apnea. You will feel a nourishing sense of pride in your appearance and the encouragement to always stay in shape and in good health.


What is the expected amount of weight loss after gastric sleeve?

Weight loss varies from one patient to another depending on several factors, the most important of which is adherence to dietary instructions and sports; Weight loss is approximately 70 to 100% of the extra weight.

Expected weight loss after the process is as follows:

  • • After the first 45 days 10-25%
  • • Month 3: 30% loss
  • • Month 6: loss of about 50-60%
  • • Month 9-12: Losing up to 100% extra weight

Why Sleeve Gastrectomy ?

Sleeve Gastrectomy, one of the simplest operations in bariatric surgeries with the lowest complication rate among other obesity surgeries, is less hunger and faster satiation (feeling of fullness) has the following merits:

  • Sleeve Gastrectomy is a safe and radical solution to obesity and its risks with 99.9% success rate with 80% to 100% of excess weight loss, which is the highest percentage of weight loss among bariatric surgeries, after which most patients feel a significant improvement in their quality of life.
  • Sleeve Gastrectomy gives you a healthy balanced eating that is enough for the body with no deprivation of eating.
  • It is conducted for all ages from 10 to 70 years.
  • Sleeve Gastrectomy neither affects the digestive function in terms of digestion and absorption nor the internal anatomy of the body, and hence you don't have to take vitamins beyond the first 6 months.
  • Significant improvement in the condition of 55 obesity-related health conditions, such as:

1) Diabetes Mellitus.

2) High blood pressure.
3) High Cholesterol in blood.

4) Osteoarthritis.

5) Sleep apnea.

6) Increases fertility in both men and women for childbearing

7) Improves sexual ability for the better.

  • Sleeve Gastrectomy increases the basal metabolic rate through the secretion of GLP1, which stimulates the secretion of insulin and therefore treats or improves diabetes (depending on type, severity and duration of diabetes).
  • Sleeve Gastrectomy has no side effects in the future, a fact proven through a few decades.
  • Sleeve Gastrectomy does not implant external tools in body, which prevents complications of possible rejection of the body to external objects as occurs in the balloon and gastric Lap-band.
  • The incomplete resection of the stomach keeps the absorption process reducing the chances of impact on the absorption of iron, as happens in surgeries that affect the absorption, so the patient does not suffer from iron deficiency anaemia.
  • The lack of effect of surgery on the absorption of calcium reduces the risk of osteoporosis, especially at the age of menopause and aging.
  • Reduce the amount of gastric acid secreted in the stomach, which reduces the risk of infectious ulcers and duodenal ulcers.
  • Sleeve Gastrectomy does not include intestinal cutting and reconnection or a change in the order of the digestive system and therefore does not suffer from dumping syndrome (rapid emptying) or intestinal disorders or problems of malabsorption of food.
  • Short operative time, takes 20 to 40 minutes.
