What is obesity?

Obesity is a chronic, debilitating, life-long disease. In today’s fast paced world coupled with hectic schedules and tighter deadlines, one’s health takes a backseat and most of us fall into the trap of unhealthy eating habits leading to obesity, which has adverse and sometimes permanent effects on the human body. NMC believes that obesity is not only a disease but a threat to life. Apart from affecting the quality of life, together with the associated medical problems it greatly reduces the average life span, and increases mortality. NMC prepares you to fight and win the battle of the bulge by helping you to understand your body and moving towards a healthier future for you and your family.

Causes of obesity

  • Sedentary lifestyles: Stressful schedules leave little time to think about healthy or timely eating, leading to gradual weight gain and ultimately make the person obese.
  • Poor eating habits: With a wide range of ready-to-eat foods available in the market, one becomes prey to choosing convenience over health and eats whatever is at hand to avoid the trouble of making fresh food. These foods are usually high in calories and low in nutritional value.
  • Genetics: Obesity can also stem from genetics as well as other environmental factors. A recent survey reported that the offspring of two obese parents are more likely to be obese.

Obesity categories: BMI range

Understanding your body type: Before we explore deeper on how obesity affects life, it is important to calculate one’s Body Mass Index (BMI), which is used to categories the grade of obesity

19-25 Ideal
25-30 Overweight
30-35 Obese
35-40 Severely Obese
35-40 + obesity-related illness Morbidly Obese
40 and above Morbidly Obese

For example if body weight = 75 kgs and height = 1.62 m, the BMI would be 28.6 and the person will be considered overweight.

How obesity affects life?

Obesity is a gradual process that slowly turns in to a life threat if not nipped at the right time.

Problems related with obesity

  • Hypertension (high blood pressure)
  • Diabetes (type 2)
  • Dyslipidemia (high cholesterol or triglycerides)
  • Heart diseases
  • Stroke
  • Gallbladder disease
  • Degenerative joint problems like Osteoarthritis, immobility & backache
  • Sleep apnea
  • Susceptibility to breast, endometrial and colon cancer

How to fight obesity?

Now that we have a better understanding of the extent to which obesity hampers our health and strains our system, there are a number of ways by which obesity can be tackled. A few of them are:

  • Controlled Diet
  • Rigorous exercise
  • Medication to overcome related illnesses
  • Surgery

Why surgery is required?

Surgical weight loss is a safe and effective alternative when other methods are not successful. NMC offers laparoscopic surgery using specialised instruments, which decrease post-operative pain, and assist faster recovery. Bariatric Surgery is one of the weight-loss procedures which aid a person in losing weight over a period of time and help maintain the weight loss with much ease. Before you take the decision to undergo surgery, you are advised to make a firm commitment to adopt a healthy lifestyle for lifelong results.

Ideal candidate for bariatric surgery

  1. Patient with a BMI over 40 – eligible for surgery based on weight alone.
  2. Patient with a BMI of 35 to 40 – with associated obesity-related illness like diabetes, hypertension, sleep apnea, dyslipidemia, degenerative joint problems.
  3. Patient considering surgery should have already tried to lose weight by other non – surgical methods. When those are not successful and obesity is a threat to health, it is time to consider surgical options.

Bariatric surgery is not suggested for whom

  1. Patients with poor health conditions making them medically high risk
  2. Major psychiatric/mental disorder patients
  3. Active uncontrolled alcohol or substance abuse patients
  4. End stage/ untreatable cancer, HIV patients
  5. People who cannot adhere to the necessary pre and post-operative dietary

Pre – surgery preparation

  • Initial consultation with the surgeon
  • Pre-operative testing: blood tests, ECG, chest x-ray, endoscopy
  • Additional pre-operative testing if medically indicated: for example cardiac clearance
  • Consultation with dietitian
  • Psychological evaluation
  • Clearance from anaesthesia service
  • High protein, low carbohydrate diet for 2 weeks before surgery. This helps in reducing the size of the Liver, making the surgery safer

Types of bariatric surgeries offered by NMC

Laparoscopic Sleeve Gastrectomy:

The Bariatric surgeon trims the stomach into a sleeve, making it smaller, 15-20% of its original size. The excess stomach is removed. This greatly restricts the amount or quantity of food you can eat at one time. Plus, the hormonal changes with the surgery curb your appetite.

Result – You lose approx. 70-75% of your excess body weight in 1-1.5 years

Laparoscopic Gastric Bypass:

In a gastric bypass surgery, the Bariatric surgeon creates a small 15-30ml pouch in the upper stomach, which restricts the food intake. Plus, re-routing of the small intestine is done, which is directly connected to that pouch. Thus the food bypasses the stomach and greater part of the small intestine, causing mal-absorption.
Result – You lose approx. 75-85% of your excess body weight in 1-1.5 years.

Laparoscopic Adjustable Gastric Banding:

Here the Bariatric surgeon places a soft silicon band around the upper part of the stomach, which can be inflated and deflated via a port, hence the degree of tightness around the stomach can be adjusted according to the individual’s need. This surgery is helpful, but the results largely depend on your strict dietary and lifestyle changes. On an average, you lose approx. 50-55% of excess body weight in 1-1.5 years.

Laparoscopic Gastric Plication

Gastric Plication is a restrictive procedure. It greatly reduces the size of your stomach and limits the amount of food that can be eaten at one time. Gastric Plication may also cause a decrease in appetite.

Gastric Balloon

It is a non-surgical procedure available for weight loss. A soft, expandable, silicone balloon is placed inside the stomach. Intra Gastric Balloon is completely reversible, and effective in temporarily reducing hunger, controlling food intake, initiating behavioral change, and achieving target weight loss of 10 to 20kg. Remains in the stomach for a six-month.
