Gastric By-pass (ROUX-Y)
Gastric bypass, also known as Roux-en-Y, is a type of weight-loss surgery that involves creating a small pouch from the stomach and connecting it directly to the small intestine.
The goal of this weight loss surgery is to reduce both the food to be consumed and the amount of fat and calories absorbed. It is recommended for overweight and obese patients who have serious health problems and cannot lose weight despite diet and exercise.
Gastric bypass surgery could be an option for you if;
- Your Body Mass Index (BMI) is 40 or higher
- Your BMI is 35 to 40 and you have a serious weight-related health problem, such as type 2 diabetes, high blood pressure or severe sleep apnea.
Your obesity physician will decide if you are eligible for this surgery after a comprehensive screening process.
Gastric bypass can reduce your risk of potentially life-threatening weight related health problems, including:
- Gastroesophageal reflux disease
- Heart disease
- High blood pressure
- High cholesterol
- Sleep apnea
- Type 2 diabetes
Gastric bypass surgery is done in the hospital. Depending on your recovery, your hospital stay may last around three to five days. Surgery is performed laparoscopically (closed). The stomach is reached through small incisions in the abdomen of the patient who is under general anesthesia. The upper part of the stomach is taken, the remaining part is stitched and turned into a pouch. The size of the organ becomes as small as a walnut. Then your surgeon cuts the small intestine and sews some of it directly onto the sac. With this intervention, you now consume less food. Foods pass into this pouch, then into the small intestine. As the foods do not fall into the duodenum, most of them are thrown out without being absorbed. So, foods are not stored as fat and weight loss starts.
How much weight can you lose?
Gastric bypass can provide long-term weight loss. The amount of weight you lose depends on your type of surgery and your change in lifestyle habits. It may be possible to lose 60 percent, or even more, of your excess weight within two years.
Diet plan after gastric bypass
- The diet plan consists of several stages. Your doctor will determine how long each stage will take and what to eat. Controlling food portions can help you manage your eating habits for the rest of your life.
- For the first few days, you can only drink a few sips of liquid at a time. This will help your stomach to heal.
- When your doctor decides that you’re ready, you can move onto stage two. This step consists of pureed food.
- Spices can be disturbing so avoid them completely. Do not eat fruits that contain too much seeds, such as strawberries and kiwi. Broccoli and cauliflower are not recommend either.
- A few weeks later, soft, easy-to-chew foods will be added to your diet.
- The fourth stage of the gastric bypass diet involves the re-consumption of solid food. It starts about two months after surgery. You need to cut or chop foods into small pieces. Large amounts of food can cause blockage. A blockage can lead to pain, nausea and vomiting.
- Taking vitamin and mineral supplements are important.
Are there any disadvantages?
- It is technically more complicated than other stomach reduction operations.
- The procedure can lead to deficiency of vitamine B12, minerals such as iron, calcium and folate. Lifetime vitamin and mineral support is required.
- Dumping syndrome may develop (Feeling of sickness, nausea and headache after consuming food)
