Gastric Bypass
Gastric bypass is a surgical procedure that can help people with obesity to lose weight and improve their health. It decreases the size of the stomach and changes the way the stomach and small intestine absorb food, making it easier to lose weight. This procedure is also called a Roux-en-Y gastric bypass.
When should I consider gastric bypass surgery?
If you are very obese and have other health problems, and have tried hard to lose weight by dieting and doing more exercise, your doctor might suggest gastric bypass surgery to help with weight loss.
Gastric bypass surgery is a very effective type of surgery for weight loss, but it is not for everyone. Discuss with your doctor which approach is best for you, and talk about what to expect. You could ask:
- What’s the average loss of weight after a year?
- What’s the average loss of weight after 5 years?
- What’s my role after surgery?
Losing weight after gastric bypass surgery can help reduce problems with type 2 diabetes, asthma episodes and blood pressure, and can help improve heart health.
Frequently Asked Questions
If your body mass index is above thirty-five and you have at least one or two of the diseases such as hypertension, coronary heart disease, type 2 diabetes, insulin resistance, osteoarthritis (rheumatism), sleep apnea, fatty liver etc... or if your body mass index is directly above forty, your age is between eighteen and sixty five, and if there is no obstacle for you to receive general anesthesia, you are suitable for this operation.
The patient is admitted to surgery the day she/he arrives. After the necessary tests are done, if there is no obstacle, the patient is taken to the operation.
On the second day after the operation, ultrasounic tests are taken and information is given about the diet list that will be applied. On the third day after the operation, they can be discharged from the hospital and they can go back to their home.
If the patient has uncontrolled diabetes (If blood sugar and HbA1c levels are high despite taking insulin),
If severe esophageal inflammation (esophagitis) due to gastric hernia or reflux is detected in endoscopy, gastric bypass is more appropriate for these patients. If there is no problem in the examination and endoscopy of the patient, gastric sleeve can be done.
You can board the plane as soon as you are discharged from the hospital.
After the operation, the patients start their diet program with liquid foods for the first month and with mashed/ puree foods for the second month. At the beginning of the third month, solid foods are started under the control of our dietitian.
The aim here is not to make the patient lose weight quickly, but to prevent the growth of the stomach by keeping the stomach volume we have created.
Although this varies depending on the person, since the operation is performed with the closed (laparoscopic) method and the hospital stay is shortened, the patients can return to their normal life on the 4th-7th day of the operation.
Although the rate of weight loss may vary depending on the age and metabolic rate of the person, the patient loses weight rapidly in the first 3-4 months of the operation. As you lose weight, the rate of weight loss in the following months will slow down and may even pause normally in some periods. The most important factor in the following months is the patient's adopting the changing lifestyle and diet and complying with this order. During these periods, the patient is supported by being regularly called for control. Patients who comply with the recommendations and lifestyle changes can lose 70% of their excess weight within 1 year.
For the patients with type 2 diabetes due to morbid obesity, 70% complete recovery can be seen after gastric sleeve operation; If the patient has uncontrolled diabetes despite using insulin or has a low body mass index and type 2 diabetes, it would be more appropriate to apply metabolic surgery to this group. With metabolic surgery, complete recovery can be seen at rates of up to 90%.
Light exercises (walking, jogging, cycling, etc.) can be started 1 week after the operation. Heavy exercises should be done on the 6th-8th days of the surgery. In patients with very high body mass index (BMI), heavy exercises are started later (after reasonable weight loss).
Young patients generally do not experience sagging as they maintain their skin tightness. Even if there is sagging, it is not general, it happens in certain parts of the body. The main problem starts after the age of 30-40; because the skin loses its elasticity. Patients who experience sagging after weight loss are referred to the plastic surgery department after being followed for 12 months after their weight remains stable or 2-3 years after bariatric surgery. It is not recommended to undergo surgery for sagging during the period when the weight loss process continues.
