Gastric Bypass Surgery: Procedure, Recovery, Cost, Risk & Complication

Gastric bypass surgery is a type of weight loss procedure, where certain modifications are made to the digestive system so that the amount is food you can consume is restricted. At times, it can also reduce the amount of nutrients your body can absorb. This surgery is only preferred when other alternative methods like diet and exercise has failed to have the necessary impact. These surgeries are collectively known as bariatric surgery.


Gastric bypass surgery is recommended if your body mass index is over 40. A high body mass index can lead to a wide range of health problems such as high blood pressure, sleep apnea and type 2 diabetes. If your body does not respond to treatments like diet and exercise only then is a gastric bypass performed.

Pre Procedure

In case you qualify for a gastric bypass surgery, you will be given instructions on how to prepare for the surgery. You need to undergo a set of diagnostic tests before the surgery. There will be limitations on what you can eat or drink, and what medication you can take. The doctor may also instruct you to start a physical exercise regimen and stay away from smoking.

During Procedure

The first step is the administration of anesthesia. This will be put you to sleep before the surgeon begins the surgery. The doctor will make use of staples to segregate your stomach into two halves – a large bottom section and a small upper section. Then the bypass is performed where the small intestine is connected to the smaller upper section. This surgery can be done by making a cut in the belly or by using laparoscope.

Post Procedure

You may be required to stay in the hospital for a couple of days after the surgery. The fluids from your intestine will be drained using a catheter for the first two days. Initially you will not be able to consume food or drink water. You may be required to wear special feet stockings to prevent blood clots. The doctor will also prescribe antibiotics and other medications to help you recover faster. Once you go home after the surgery, you will have to eat pureed food and avoid solid food altogether till the recovery process is complete.

Risk & Complication

Like all surgeries, gastric bypass surgery also carries certain risks. One of them is the stomach returning to its original size due to stretching. The staples can come off. Due to the bypass, the body’s ability to absorb nutrients from food decreases. The connection between the stomach and the small intestine can narrow down resulting in vomiting, reflux and nausea. Dumping syndrome may also occur when food moves very rapidly from stomach to small intestine.

Losing weight too quickly may also result in gallstones.

More Info

The price of undergoing a gastric bypass surgery in India can range from 3 lakhs to 5 lakhs. You have to keep in mind that this surgery is only carried out only if other methods like diet and exercise have failed to come up with the necessary results.

Alcohol & Gastric Bypass - Can They Be Mixed?

Alcohol & Gastric Bypass - Can They Be Mixed?
Gastric bypass, one of the weight loss surgeries bring about many changes and alterations (physiological, metabolic, hormonal) in your body. The gastric bypass surgery rearranges the stomach into an upper pouch (the smaller part) and a relatively larger lower part. It is the small pouch that is connected to the small intestine, where the absorption of nutrients and minerals from the ingested food takes place. The surgery plays a significant role in limiting the intake of food. Thus, post-surgery, a person's body reacts differently than it used to before the surgery. Many, if not all, people experience difficulties in coping up with the changes. Patients are often advised to refrain from alcohol consumption after the gastric bypass surgery. Surprisingly, and quite alarming, cases of alcohol abuse increases post the surgery. According to a survey by the American Society for Metabolic and Bariatric Surgery, few people, who had no prior history of alcohol abuse developed one after the weight loss surgery. What triggers the alcohol abuse in some patients is still a debatable issue. Many patients experience an emotional breakdown, stress, anxiety, and depression after the surgery. People who needed no reason to binge on food are suddenly expected and made to consume a limited quantity of food. Unable to do what they loved doing the most, people look for an alternate solution. As expected, in most cases, alcohol becomes the much-needed solution. What started as a means of distraction gradually becomes an integral part of life. Hormonal changes associated with the surgery can also result in panic attacks, stress, and anxiety. Incidences of alcohol abuse may also be high in patients who had a history of drinking (regular or occasional) and smoking before the gastric bypass. Under normal circumstances (before the weight loss surgery), there is a partial enzymatic breakdown of the consumed alcohol in the stomach before it passes into the small intestine. However, post-surgery, the small size of the stomach does not facilitate such enzymatic breakdowns. Thus, the alcohol passes into the intestine, where it gets rapidly absorbed. As a result, a person gets into an inebriated state at a faster rate. It is because of this reason that doctors advise the patients to keep away from alcohol as much as possible after the surgery. To keep away from or reduce the instances of alcohol abuse after the gastric bypass surgery, Look for healthier and low-calorie food options when you get an urge to eat. Meditate, go for morning and evening walks. These physical activities act as great stress busters. If you are feeling low or going through an emotionally low phase, share it with your loved ones. Do not suppress your emotions. Consult your attending physician in case of any physical discomfort

Bariatric Surgery - A Boon For Diabetic Patients!
Diabetes is a gnawing problem that affects millions throughout the world. It is a disorder that if overlooked can lead to serious diseases; cardiovascular ailments, problems related to vision, kidney problems and many more. While medication tries to regulate your blood sugar levels, it is not always unfailing. Medication along with changes in your diet and lifestyle can still not improve your condition in certain cases. At times it is hard to increase the insulin production in a person's body even after administering medicines solely known for their efficacy. Such kind of diabetic patients can therefore benefit from a Bariatric surgery. What is a Bariatric surgery? Bariatric surgery doesn't refer to a single operative method. It involves a host of surgical procedures conducted on a person to rid him or her of obesity. Obesity in combination with diabetes can make a person's life miserable. The treatment of one can come in the way of curing the other. A diabetic patient who also suffers from obesity usually finds it hard to lose weight in spite of exercising or being on diet. Surgery comes to their rescue. This kind of surgery should be fallen back upon as the lender of last resort that is to say when other solutions have not helped. Bariatric surgery is always performed under skilled supervision. It might include reduction of the size of your stomach, removal of a portion of the stomach, or even gastric bypass surgery. How does Bariatric surgery help reduce Diabetes? Diabetes can be of three basic kinds; Type 1 diabetes in which the body produces no amount of insulin. Type 2 diabetes in which the body produces an insufficient amount of insulin or Gestational diabetes that pregnant women tend to contract. Bariatric surgery proves to be very advantageous for patients of Type 2 diabetes: 1. Surgery lowers blood sugar levels considerably. Research shows people with acute diabetes made huge improvements after having undergone a Bariatric surgery. Their blood sugar levels dropped by a noticeable percentage and they felt healthier. Reduced blood sugar is an almost immediate effect in some while for others it does take some time. 2. Bariatric surgery exercises a control over cholesterol, blood pressure and triglyceride levels. 3. The impressive benefits of this operation for a Type 2 diabetes patient are not superficial or temporary. If the patient adheres to the lifestyle prescribed by a doctor, takes medication regularly and follows the basics of post- operative care he or she is likely to remain beyond the ambit of this metabolic disorder. 4. It successfully takes care of ailments resulting from diabetes. 5. Bariatric surgery can eliminate the need for medication or it can reduce the dosage of medicines you take.
