Gastric sleeve or sleeve gastrectomy is a well-known weight loss surgery which is favored by the obese and surgeons. It helps the patient to feel sated sooner and experience a long-term weight loss result. Sleeve gastrectomy used to be just a part of the two-step duodenal switch (DS). When the surgeons observed remarkable positive effects on the health condition and weight loss, they decided to make use of it as an independent weight loss treatment. Depending on the case, in gastric sleeve procedure, between 60% and 80% of the patient’s stomach is removed and a tube-shaped or banana-shaped stomach or a “sleeve” with the capacity of accepting a smaller portion of food is created. This sleeve is the connection between the esophagus and the small intestines. 6 months after the procedure, 50% of the patient’s excess weight is lost and fat loss process continues until 2 years when the patient reaches their normal weight.

Why gastric sleeve?

As a dangerous issue, obesity causes many problems and diseases which can either be prevented or cured by gastric sleeve. Obesity consequences fall into two categories, psychological and physical. Anxiety, depression, body dissatisfaction, low self-esteem, low quality of life and low self-confidence are the psychological consequences of being overweight. Physical consequences are cancers and chronic diseases. Sleeve gastrectomy is one of those effective treatments with long-lasting results which either cures or improves the patients who are struggling with the negative effects of obesity.

Gastric sleeve is a resolution which restricts the risk of being infected by obesity-related cancers, like colon cancer, endometrial cancer, pancreatic cancer, and postmenopausal breast cancer. Asthma, diabetes, sleep apnea, migraines, venous stasis disease, infertility, gastro-esophageal reflux disease (GERD), cardiovascular disease, stress urinary incontinence, high cholesterol and metabolic syndrome are the physical consequences of obesity which get cured after gastric sleeve. Also, the pressure on the knees, which is one of the disadvantages of being overweight, decreases after the surgery.

How is a gastric sleeve performed?

Unlike open surgeries, sleeve gastrectomy causes less pain and scars. After general anesthesia, between 2 and 5 incisions are made on your abdomen. Different tiny instruments and a laparoscope (a small tube with a camera and a light source at its end that helps your surgeon to see inside your stomach) are introduced to your body. 80% of your stomach is removed and the two lines are stapled, making a sleeve-like stomach. The surgery needs between 1 and 2 hours. After two days, you are released from hospital.

What to do before a gastric sleeve?

Make sure that you consider what is listed below before your surgery. They will help you have an easier and less risky surgery with better results. You are recommended:

  • Not to hesitate to ask your surgeon any kind of question which makes you properly prepared for your surgery.
  • To have blood tests, x-ray and an ECG.
  • To follow pre-operative diet two weeks prior to your surgery, which includes: no sugar, lower carbs, more protein, clear liquids and broth, and more vegetables and fluids;
  • To stop taking certain medication (as your doctor instructs).
  • To stop using tobacco, food and drinks 12 hours prior to your appointment;
  • To lose weight as much as you can by exercising and diet.

What is gastric sleeve recovery and post-operative care?

As gastric sleeve is an invasive surgery, it requires a short stay in the hospital. Depending on the case, you are released within 2 days. Within a week, you can get back to your normal routine. In the second week, you are fully recovered. One important point is that gastric sleeve is a strong tool for weight loss, but long-term success depends on your post-operative cares and your adherence to your diet, new eating habits and exercises. What follows are the eating instructions for you within a period of five weeks after your gastric sleeve surgery.

First week: clear liquids, including water, juices, broth, and decaffeinated tea.

Second week: liquids plus protein shakes.

Third week: soft pureed foods like soup.

  • To have 3 complete meals every day.
  • That dense foods are important.
  • To take supplements in order not to omit any necessary nutrient. Some of them are: iron, vitamin B, multivitamin, calcium, and folic acid. The dose of supplements should be determined by your doctor.
  • To exercise at least 30 minutes every day (four days per week is necessary). Required exercises are flexibility, strength, and endurance.
  • To ensure that there will be some people around you who help you during your recovery process.

What are common side effects and complications of gastric sleeve?

Although more than 90 percent of the gastric sleeve patients observe satisfying results, there might be some complications and risks which are listed below:

  • The leakage of food from the stapled line (to avoid it, the stapled line is sewed)
