Frequently Asked Questions

Most of obesity is hormonal – hormones in an obese person ensure that the body does not go below a high weight it has become used to. Most people have a genetic disposition to obesity. Other triggers are stress, puberty, pregnancy, side effects of medication etc. Essentially we are fighting against our own bodies. The problem lies with the stigma associated with obesity. People tend to believe it’s their fault (and the society at large also believe) – that they eat too much, don’t exercise, or can’t control their hunger. This is completely wrong, it is a misconception. The increase hunger and the lethargy are actually due to the hormonal disturbances in the body and ar a mechanism to maintain the increased weight.
The first and most important way to lose weight is by modification of diet and increasing physical activity. Dietary changes include reduction of total calorie intake and modification of composition of diet.
Diet should include reduction of carbohydrates and increase in proteins and fibre. It is helpful to be in touch with a qualified nutritionist for planning of a diet according to your requirements.
Regular exercise, at least 4-5 days a week, is essential to lose weight besides improving general fitness level and well-being. A trainer can guide you to exercise properly in order to get maximum benefits and at the same time avoid injuries.
Diet and exercise have been shown to cause a 5-10% weight loss over a period of time. To maintain the weight loss it is important to continue the healthy diet and exercise, otherwise you are likely to gain the lost weight.
There are some medications which are available to help lose weight but most of them are associated with significant side-effects, some of which may be troublesome.
There are a lot of herbal products also available, but it is difficult to determine their efficacy and safety.
Apart from medicines, surgery is an important method to help you lose weight, especially in people who are extremely obese (BMI more than 35, 33 in Asian populations). This surgery is not plastic surgery (which is used to remove fat from various parts of the body in order to give shape to the body), but it changes the way you feel hunger and the way you eat. It will cause you to lose weight gradually over a period of time (typically one and a half to two years) and will allow you to lose more weight than any other method (typically 60-70% of your excess weight). It is also currently the only way to lose large amount of weight and to keep it off. The weight loss you get with surgery is durable weight loss.
It is the surgical treatment for morbid obesity and diabetes mellitus. These are weight-loss surgeries that involve making changes to the digestive system to help you lose weight. It is done when diet and exercise don’t help you to lose weight.
Bariatric surgery is done to help your body lose excess weight and reduce the risk of weight-related health problems such as heart disease and stroke, high blood pressure, sleep apnea, type 2 diabetes, and non-alcoholic fatty liver disease. It is also done for infertility and PCOS due to excess weight.It is very different from liposuction which involves removal of fat from under your skin to shape your body.
Any adult who is morbidly Obese (In Asians and Indians BMI more than 32.5 or BMI more than 27.5 with associated problems due to obesity) is a candidate for surgery provided the risk of surgery is not too high. Surgery is recommended with caution to children below 18 years and people above 65 years of age, but can be done if the benefits outweigh the risks.
Apart from weight loss and increase in general fitness, many diseases which are linked to obesity are remarkably improved Bariatric Surgery. Diabetes is improved in a large proportion of individuals and medicines can be stopped in two-thirds. It may come back after many years but the requirement for medicines is reduced. BP is easier to control and medicines may be stopped. Breathing problems like OSA are resolved. Life expectancy is also improved.
Most patients stay in hospital only 48 hours and can resume work in less than a week. After the weight loss surgery, the bariatric surgeon will ask you to avoid any type of food for one to two days so that the stomach and digestive system can heal. You will be on diet for a few weeks and for the first few days only liquid will be given to you, then soft food and eventually regular food. You will be started with few vitamin supplements at a later date.
Bariatric Surgery in modern times, especially if done by the laparoscopic or robotic method, is extremely safe. The risk not very much more than routine operations like gall-bladder or hernia surgery.
There are short-term and long-term risks associated with bariatric surgery: Short-term risks include excessive bleeding, infection, breathing problem, blood clots, adverse reactions to anaesthesia, leaks in the gastrointestinal system, and death in rare cases. Long-term risks include bowel obstruction, gallstones, low blood sugar, malnutrition, ulcers, vomiting, acid reflux, and death in very rare cases.
The most common side-effects of weight loss surgery are acid reflux, nausea, vomiting, infection, obstruction of the intestines, weight re-gain or failure to lose weight, and anaestheisa related problems.
You should be motivated to lose weightand you need to have tried a diet and exercise programme. After the operation you will be up and about on the same evening or the next morning. Most people are able to join work in less than a week. You will have to avoid lifting heavy weights for a month or so. You will need to drink water regularly. You will also need to consult with the nutrition expert on a regular basis for the first few months to become familiar with the diet plan after surgery. Care needs to be taken about what and how frequently you eat to get the most benefit from the surgery. Exercise is also essential to get the maximum weight loss. Vitamin and mineral supplements may need to be taken after surgery.
Right after surgery there will be no weight loss as no fat is removed during the surgery. Rather there will be a gradual and sustained weight loss starting with the first month and lasting for up to two years until your weight stabilises. After that there will be no further weight loss; in fact you can gain some weight if you are not careful about your diet and exercise.
It is recommended that you see the doctor regularly after surgery at varying intervals depending on your situation. Typically the visits are scheduled after 1, 3, 6 and 12 months after surgery. Thereafter yearly visits are appropriate.

Myths About Bariatric Surgery

Fact: The fact is that every type of surgery has some potential risks and complications. But a number of recent advances have been developed to minimize the risks. Before having the surgery, you should ask your surgeon about the risk and benefits of the surgery.
Fact: Yes, bariatric surgery has a significant impact on weight loss. But this is not the only benefit of the surgery. The fact is that it also eases other conditions like sleep apnea, acid reflux, and even diabetes which can be caused by obesity.
Fact: In the past, there was no insurance pay for bariatric surgery. But at present it has been changed, and many insurance companies are now covering the surgical procedures for weight loss. If you are going for a weight loss surgery, contact your insurance company as every plan is different. Your surgeon may also assist you in working with your insurance company to determine the recommended procedure to be covered.
Fact: People may regain weight after several years of their surgery. The percentage is low and they can be successfully managed with diet/exercise/medications in most instances. Most of the patients who have undergone the surgery have maintained a successful weight loss. The weight loss or gain mainly depends on the diet you follow and the disease process. After the surgery, your surgeon may suggest you to develop healthy eating habits and to avoid poor nutrition habits that originally led to your weight gain.
Fact: After the surgery, you need to change your eating habits. You should learn how to eat for sufficient energy and how to make healthy choices. You need to eat less, but healthy foods. Your ability to taste the food and your preferences may be changed.
Fact: There are different types of procedures for weight loss, and not all of them would involve stomach stapling. Some procedures would reduce the functioning size of the stomach and others would bypass the parts of the digestive tract to reduce the absorption of the nutrients and calories.
Fact: Many people do not know that bariatric surgery is performed through laparoscopy. In this procedure, the scars are small and do not require any plastic surgery.
Fact: If you have had open surgery, you are still a right candidate for the laparoscopic surgery. But before undergoing the surgery, a proper evaluation is needed.
Fact: The fact is that not every obese candidate is the right candidate for the surgery. Before the surgery, each person has to be thoroughly examined, investigated, and counseled.
Fact: Fat reduction surgeries are liposuction and abdominoplasty, and these do not fall into the category of bariatric surgery. Liposuction and other similar procedures are suitable for the reduction of fat in specific areas of the body like the tummy and it cannot be done on whole body.
Fact: Bariatric surgery is good for you so that you can ditch those medications. Along with the reduction in weight, it can also help you to change your body chemistry.
Fact: You need to have knowledge on which type of surgery is suggested for you. If you are a diabetic, gastric bypass surgery is preferred to reduce the size of the stomach and bypass some part of the intestine. If your BMI is up to 40, then sleeve gastrectomy is preferred to remove the entire banana- sized portion of the stomach. There are several other considerations which come into play while deciding which operation is the best suited to you.
You may not accept your weight as an unchangeable condition in your life. Bariatric surgery is a good option to reduce weight and maintain the desired weight. Believe in facts and swipe the myths related to the surgery.
