Obesity Surgery

Sleeve Gastrectomy

The main reason why obesity is accepted as a surgical treatment is that it can be done quickly, it causes less injury to the patient, patients lose weight well and obesity-related side effects improve more quickly. In addition, it should be seen as an important advantage that more advanced second-stage obesity surgery can be easily performed when necessary.

It has been determined that after this surgery, patients lose 50% to 80% of their excess weight in approximately 12 months, and other obesity-related diseases also improve.

How is Gastric Sleeve Surgery Performed?

The larger part of the stomach is cut out and a gastric tube with a volume of 60 to 120 ml is created.

Weight Loss in Gastric Sleeve Surgery

Weight loss in sleeve gastrectomy surgery occurs through 2 mechanisms:

1. Weight loss due to mechanical restriction and reduction of stomach movements by reducing stomach volume,
2. Since the stomach tissue that produces a substance known as ghrelin is removed, a hormonal change occurs and weight loss occurs. Since the fundus region of the stomach where ghrelin is produced is removed in Sleeve Gastrectomy Surgery, appetite decreases and weight loss occurs.

What is the result of gastric sleeve surgery?

Gastric sleeve surgery is an important obesity surgery that shows its effects in a short time, 35-70 percent of the total excess weight is lost in six months, and 33-81 percent of the excess weight is lost in the 12th month. The weight lost in three years is close to the weight lost after Gastric Bypass surgery.

Weight Gain After Gastric Sleeve Surgery?

After sleeve gastrectomy surgery, weight gain may occur again if the stomach tube expands over time.

Reasons for Weight Gain:

• Using excessively large spark plugs.
• Inadequate removal of the posterior stomach wall
• Excessive pressure on the stomach tube due to large bites.
• Recurrent vomiting.
• Obstruction in the stomach or intestines

If You Gain Weight After Gastric Sleeve Surgery

With the laparoscopic method, the excess of the expanded stomach can be removed.

• He or she may undergo gastric bypass surgery.
• It can be performed with laparoscopic duodenal switch surgery.

Nutrition After Gastric Sleeve Surgery

Sleeve gastrectomy surgery is the removal of 2/3 of the stomach to narrow the stomach volume, the remaining stomach volume is approximately 90-100 ml and the reconstructed stomach is more or less tube-shaped.

The main purpose of this surgery is to reduce the stomach volume and thus provide a feeling of satiety with small portions.

Gastric Bypass Surgery

This surgery causes people to lose weight through two mechanisms. In the surgery, a small stomach is created to create stomach volume; the small stomach is then connected to the small intestine and works by allowing food to bypass the large stomach and pass into the small intestine.

Patients consume less nutrients, and since absorption from food in the intestines is impaired, fewer calories are taken in. Eating less and absorbing less leads to weight loss in patients.

Mini-Gastric Bypass (MGB):

There are two weight loss mechanisms with this surgery.

1-With the tube stomach created, excess food intake is prevented and the rate of eating is reduced.

2-With the connection made between the new tube stomach and the small intestine, food passes directly into the small intestine without going through the large stomach and intestine, and the absorption of the ingested food is prevented.

Mini-Gastric Bypass (MGB) surgery is often compared to Roux en Y Gastric Bypass (RYGB), which has the same mechanism of action. The most important advantage of MGB is that it is technically easier to apply and the surgery time is shorter.

Roux en Y Gastric Bypass (RYGB)

RYBG surgery has two effects.

1-Food intake is reduced by reducing stomach volume.

2- Foods, especially high-calorie sugary foods, are prevented from being absorbed because the majority of the stomach, duodenum (duodenum) and the initial part of the jejunum (small intestine) are bypassed.

Following food intake, nutrients travel from the esophagus to the small stomach and then directly into the small intestine (they bypass the large stomach, duodenum and first part of the jejunum). Thus, since all foods do not pass through these areas of the digestive system responsible for absorption, they pass directly into the small intestine without being absorbed.

On the other hand, secretions coming from the deactivated regions (gastric juice, liver bile, pancreatic juice and duodenum enzymes) mix with the food through the connection with the small intestine and pass to the common pathway.

Nutrition After Bypass Surgery

These surgeries are surgeries performed by reducing the stomach volume and the areas where nutrients are absorbed from the intestines, and they are surgeries that provide weight loss due to both absorption and limited food intake.

In bypass surgeries, following a liquid, puree, soft solid and healthy diet program step by step until the stomach and intestines functions are fully restored will allow the body to repair itself and allow you to recover without any problems.
