Gastric bypass is the most commonly performed surgery for weight loss. It is mostly recommended if all other means of weight loss like aggressive exercise, diet or a combination of both etc. fail to give results. The gastric bypass surgery works by changing the way stomach and small intestine handle the food eaten by the person. The surgery is done to reduce the size of stomach so that the person feels full soon with less food and less calories.
Who all can undergo gastric bypass surgery?
Gastric bypass surgery is recommended to individuals with following conditions who have unsuccessfully tried to lose weight:
- A BMI of 40 or more (extreme obesity)
- A BMI of 35 or more and a serious medical condition
- Severe obesity
- Inability to lose weight through diet and exercise
- Obese individuals who have excessive hunger and/or need big portions to feel satisfied
- It is also indicated in those obese persons who are at risk of developing potentially life-threatening weight-related health problems like type 2 diabetes, heart disease, high blood pressure, stroke, severe sleep apnea etc.
How will gastric bypass surgery aid weight loss?
Gastric bypass results in weight loss by:
- Limiting the food intake as the new and small stomach can hold limited amount of food
- Restricting the absorption of calories and nutrients by your body
- Altering the gut hormones in a way so that the person feels fuller early and for longer
Gastric bypass surgery procedure
Once a person decides to undergo the gastric bypass surgery, different lab tests and exams are done to make sure that a gastric bypass is right for the person. Also, there will be some changes in the diet and lifestyle some weeks before the surgery. Doctor may prescribe certain medications to help your body handle the upcoming surgery.
Surgery is performed under general anaesthesia in the following two steps:
- The first step involves making stomach smaller. This is done by dividing stomach into a walnut sized small upper section and a larger bottom section. The division is done using staples. The upper small section of the stomach is now called pouch, and this is the place where eaten food will go after surgery. The large bottom section is not utilized now. Pouch can hold only about 1 ounce of food that will result in less intake of food and hence less calories resulting in weight loss.
- The second step is the bypass. This involves making of a connection between the pouch and a small part of small intestine (the jejunum) through a small hole. The eaten food travels from the pouch into this new opening of the small intestine. This way food is bypassed and results in absorption of fewer calories and weight loss.
The gastric bypass surgery can be done as an open procedure by making a large incision in the abdomen or laparoscopically by making smaller incisions in the abdomen and using laparoscope and other small instruments.
Risks associated with gastric bypass surgery
After gastric bypass surgery, patient may be at risk of the following:
- Pouch stretching: The pouch made during surgery may stretch over time and grow bigger in size resulting in increased eating.
- Staple lines breakdown: The staples used to make the two parts of stomach may fall apart, thereby resulting in increased food intake.
- Nutritional deficiencies: As the body gets less foods and that food is also bypassed, there can be deficiency of nutrients including vitamins and minerals.
- Stomal stenosis: The connection between stomach and intestine may get narrowed resulting in reflux symptoms like nausea, vomiting, or inability to eat.
- Dumping syndrome: This syndrome may occur when food starts to move very quickly from the stomach to the small intestine. This may cause symptoms like nausea, vomiting, fainting, sweating and sometimes diarrhoea after food intake. The syndrome makes the person extremely weak.
- Gallstones: Quick weight loss after gastric bypass surgery can cause gallstones.
These all are just expected complications and most of the patients undergoing gastric bypass surgery do not get these at all. Moreover, all these are manageable conditions and should not deter your decision of undergoing gastric bypass surgery.
Post Procedure Care
- Patient is shifted to the post-operative room soon after the surgery for few hours to monitor any abnormal signs and symptoms.
- Soon after the surgery, patient is given medications for pain relief and antibiotics to prevent infection.
- A catheter is placed into the stomach through the nose to drain fluids from the intestine for the first 1 or 2 days.
- Also, there will be a catheter in the bladder to remove urine.
- Ambulation is encouraged soon after the surgery.
- Patient is not allowed to eat for first 1 or 2 days to allow healing of the stomach and intestine.
- After 3 days, a specific diet is introduced for 12 weeks that starts with liquids and then pureed or soft foods are slowly given to the patient.
- Patient wears special stockings on legs to prevent formation of blood clots.
- Patient can restore normal activities within 1 or 2 months after going home.
- Patient is advised to avoid lifting any heavy objects or doing other strenuous activities.
- Patient can have normal food almost 6 weeks after surgery.
- Frequent medical check-ups to monitor the health of the patient are advised for first 6 months after surgery.
- Follow the dietary and lifestyle instructions provided by the surgeon to reduce and maintain weight loss.
