Obesity is a global health crisis, and it has significantly impacted India as well. The National Family Health Survey (NFHS) 5, conducted in India between 2019 and 2021, revealed 24% of adult women and 22.9% of adult men in India suffer from obesity. Considering the large population of India, you can comprehend why obesity is deemed a national health crisis.
Bariatric surgery is one of the most useful treatments for patients with serious comorbidities and medical complications caused by obesity. The top bariatric surgeons in South Delhi can help you get the required weight loss through safe and effective surgical procedures. It is important to note that bariatric surgery does not work automatically.
It also requires qualification and lifestyle management before and after the surgery to meet your health goals. So, let’s take a closer look at bariatric surgery and bariatric surgeons in South Delhi. We’ll learn more about how you can take the most benefit of the expert weight loss care near you in South Delhi at the MASSH Super Speciality Hospital.
The World Health Organisation (WHO) defines obesity as a chronic, relapsing disease that’s caused by complex genetic, neurobiological, and environmental factors. Medically, obesity is defined using a Body Mass Index (BMI) scale. Even though the BMI scale is imperfect, as proven through many medical studies, it is the standard for defining whether a person is obese or not. The BMI scale is extremely important because patients who do not qualify as obese on the BMI scale are often not eligible for bariatric surgery. So, here’s a brief overview of the BMI scale and how it defines obesity medically.
The BMI scale uses a person's height and body weight to determine whether they are underweight, normal, overweight, or obese. The WHO defines obesity as any person who has a BMI score of above 30. A BMI score of above 25 qualifies someone as overweight. Obesity is a complex medical condition, and the BMI score does not adequately put into context the medical risks of obesity. Unchecked obesity can have long-term health risks and significantly impact a person’s life expectancy. So, it is crucial to understand the medical risks of obesity, along with its medical definition.
Obesity is a chronic illness that impacts your health directly and indirectly. The different organ systems in the body, like the endocrine system, cardiac system, digestive system, and neurological systems are both directly and indirectly impacted by obesity. This is why the medical risks of obesity are categorised into direct and indirect medical risks. It is crucial to note that both the direct and indirect medical risks of obesity can seriously impact your health and shorten your lifespan if left unchecked.
In its simplest sense, obesity is additional fat in the body that causes increased weight. The human body is extremely intricate and elegantly designed. Obesity causes the organs to push against one another due to the additional fat in the body. It also puts excess stress on your musculoskeletal system. These effects have the following impact on your overall health.
Sleep apnea is not just a condition; it also independently impacts your health in many ways. This brings us to the indirect medical risks of obesity. These include a higher risk of hypertension (high blood pressure), cardiovascular diseases, type-2 diabetes, kidney failure, and liver failure.
Bariatric surgery is one of the only long-term surgical treatment options for obesity. Unlike surgeries like liposuction, bariatric surgery is not cosmetic. It is a medically recommended surgery for patients who are at a serious health risk because of obesity and must lose weight in order to extend their lifespan. It is also recommended for patients who have not had success losing weight through other weight loss treatments.
There are different types of bariatric surgery, and each of them has a different purpose. However, for the most part, the goal of bariatric surgery is to alter your digestive system to alter how many calories you can consume and absorb. Bariatric surgery also rewires the neurological pathways related to hunger between your digestive system and brain. This helps patients lose weight.
However, one of the most important facts regarding bariatric surgery that you must know is that bariatric surgery does not work by itself. It still requires effort from your end to follow a new lifestyle and dietary routines. Only then can patients lose weight and reduce the life risk associated with comorbidities.
There are several qualifying criteria for a bariatric surgery. Here is a brief overview of the qualifying factors for bariatric surgery.
There are different types of bariatric surgery, each with a different surgical process and patient outcome. Here are the best bariatric surgeries offered by top bariatric surgeons in South Delhi at the MASSH Super Speciality Hospital.
The 3D advanced laparoscopic sleeve gastrectomy is a minimally invasive surgery that involves the removal of around 85% of the stomach. The surgery decreases the size of the stomach and helps restrict food intake. A smaller stomach allows the patient to get full with minimal eating, allowing them to lose weight successfully. The surgery is performed using 3D visualisation at MASSH Super Speciality Hospital, which helps in quicker surgery times, lower surgical risks, and faster recovery.
A Roux-en-Y gastric bypass surgery is a highly advanced minimally invasive surgical treatment for obesity. It involves making a pouch in the stomach the size of an egg to minimise food intake. The pouch is then connected to the lower end of the divided small intestine. The upper part of the small intestine is connected further down, which creates the ‘Y’ shape. This surgery is one of the most effective bariatric surgeries. At MASSH Super Speciality Hospital in South Delhi, 3D visualisation and experienced surgeons ensure safer surgical experiences.
The 3D Single Anastomosis Duodeno-Ileal Bypass with sleeve gastrectomy, as the name suggests, is a combination surgical procedure, combining a sleeve gastrectomy with an anastomosis. The surgery involves creating a pouch in the stomach and then performing a connection between the duodenum and the ileum. This is an aggressive surgery, which requires long-term post-surgical care. However, it is also one of the most efficient weight loss surgeries, which allows patients to lose over 90% of excess weight in one year.
Similar to a Roux-en-Y gastric bypass, the 3D Biliopancreatic Diversion with Duodenal Switch also involves making a stomach pouch and connecting it to the lower part of the small intestines, bypassing most of it. This helps reduce calorie intake and diverts food from most of the small intestine. Much like the SADI-S, the BPD/DS requires long-term postsurgical care to be successful. The 3D visualisation offered at MASSH Super Speciality Hospital ensure minmal bleeding and tissue damage during surgery.
The mini gastric bypass surgery is as effective as a Roux-en-Y gastric bypass surgery; the ‘mini’ comes from the fact that this surgery takes a shorter timespan for surgeons. The 3D visualisation also helps improve the surgical outcomes and lower the surgery time further. A 3D mini gastric bypass involves creating a tube-shaped stomach pouch, which is connected with the small intestines in a loop. The small intestine loop is called the ‘omega loop.’ This surgery helps patients reduce food intake and absorption of calories from food by bypassing the duodenum and parts of the jejunum.
