Patient’s Guide to Bariatric Surgery

Obesity is a very common problem in today’s time even in India. The epidemic that started in the western world is fast spreading in India. Here, I am going to focus the discussion more on morbidly obese people for whom, a Bariatric (Obesity surgery) surgery is the best treatment option. Generally, there are a lot of queries, doubts, concerns and misunderstanding related to Bariatric and weight loss surgery among the obese people in India. This article will address these issues.

A Basic understanding of Obesity and weight loss options

Before we discuss Bariatric surgery, we need to understand a few basic things. This includes, what does obesity means, what are the causes, what are the grades of Obesity, how are we different than the western population, and what are the treatment options.

What is Obesity?

First of all, let us be very clear that obesity does not mean being overweight. Obesity is not just excess fat or kilos deposited in your body. Obesity is a disease recognized by the World Health Organization. It has a set of metabolic, hormonal, and behavioral changes associated with it. It affects your eating and activity preferences and has a significant impact on the quality of your life.

Causes of obesity

We need to understand that the cause of obesity is multi-factorial. The causes include our changed dietary habits, our lifestyle including our physical activity levels, changing job profiles, changing social life, social media, the availability of use of machines for lots of daily activities. And this understanding of the cause has to be judiciously and practically applied in fighting obesity. Only then shall we achieve good results.

Grading of obesity

All obese people are not the same. This means, all persons having a BMI of more than 30 do not have the same medical risks. The problems, medical, and others increase with increasing BMI. Thus, if your BMI falls between 30-35 you will be considered class I Obese, if your BMI is 35-40 then you are class II or severely obese. And with BMI between 40-50, you fall in class III or the morbidly obese category. Your BMI of more than 50 makes you a super obese person. What it means is, the problems faced by obese people depend on many things including the grades of obesity. Like, if you have obesity-related medical problems then even with BMI between 35-40, you will be considered morbidly obese. This grading of severity is important to understand your treatment options and thus the decision-making.

Approach to weight loss

Finally, the approach towards weight loss has to be individualized for each and every person. You are probably aware of many different weight loss options including dieting, herbal medication, exercising, and many weight loss clinics. The approach depends on your BMI, age, medical problems faced their expectation, and their lifestyle. Grossly, I would say that a healthy lifestyle and diet are part of the strategy for all obese persons.

Medications and some temporary procedures life endoscopic balloon placement can be of help to some selected patients. The aim of medication and balloon is to help in the initial weight loss attempt with diet and exercise. However, obesity surgery has now become a safe and reliable weight loss procedure when performed by experienced surgeons. Weight loss surgery is the only option that has consistently achieved adequate and sustained weight loss. And if you are morbidly obese, then Bariatric (Obesity) surgery followed by a healthy and active lifestyle should be your strategy.

Understanding Bariatric (Obesity) surgery

Bariatric (weight loss) surgery is the only option in today’s time that has shown consistent, significant, and long-term weight loss. Hence for all those people who need to lose significant weight, should consider the option of bariatric surgery. Especially, when they are suffering from obesity-related medical conditions. These surgeries give excellent results in terms of weight loss and improvement in many obesity-related medical problems. Thus improving the quality of life of these patients.

What is a Bariatric (obesity) surgery

In very simple words, bariatric surgery is a surgery of your stomach and intestine, with the intent to make you lose weight. This happens by restricting your food intake and by changes in your gut hormone and metabolism. Today, almost always these surgeries are done by a minimally invasive method, that is by a laparoscopic method. No fat is removed in these surgeries, and all weight loss occurs gradually, over the period of 12-18 months after surgery. In the end, I would like to clarify that it is not cosmetic surgery. It is done with the intent of improving the overall health of an obese person. Bariatric (weight loss) surgery is now commonly done in India with excellent immediate and long-term outcomes.

What are the likely benefits of Obesity (Bariatric) surgery

Depending on the type of surgery, the patient’s condition & lifestyle, anywhere from 70 to 90% of your Excess Body Weight (EBW) will be lost over a period of 6 months to two years. Most patients lose weight rapidly in the initial few months. After a few months, the rate of weight loss reduces but you continue to lose weight up to 18 to 24 months after the procedure.

After surgery, there will be an improvement in all your obesity related medical problems. Some of these problems can get resolved completely. You can see the image to know what all conditions improve after obesity surgery.

Fertility improves after obesity surgery. If you are a lady, you will be advised to avoid pregnancy for at least two years after surgery, in order to avoid the stress of pregnancy and childbirth during the period of rapid weight loss. You are strictly advised to use contraceptive methods during this time and plan pregnancy after your weight stabilizes. There are no such restrictions for a male undergoing this surgery.

One year after the surgery, you will be leading a happier, healthier, and more active life. There will be a drastic improvement in your quality of life. This is the exact reason why bariatric (weight loss) surgery is becoming more and more common in India.

How much does Bariatric surgery cost in India

Cost of Bariatric (Obesity) surgery in India would depend on a lot of factors. The main variables that would affect the cost are

  • Type of surgery
  • Your medical condition
  • The quality of consumable products, especially staplers used

The cost of surgery would be based on the procedure chosen. The cost for bypass procedure would be a little more than sleeve gastrectomy surgery. Also if you have major heart, kidney or breathing problems the cost would increase. This is so because, specific treatment regarding these conditions may be needed before and after surgery. Also hospital stay may be increased and may also need a stay in an intensive care unit. Lastly, but most importantly, in an event of a complication the cost will increase.
