What is Obesity?

Obesity is a complex disease characterized by abnormal or excessive accumulation of fat in the body that may impair health. People who have obesity are prone to develop heart disease, diabetes, high blood pressure, and cancer.

How obesity can be identified?

What are the causes of Obesity?

The primary cause of obesity is the energy imbalance between calories consumed and calories expended. Overweightness is commonly caused by overeating and a sedentary lifestyle. For instance, if you consume high amounts of energy, particularly fat and sugars, but do not burn off the energy through exercise and physical activity, much of the surplus energy will be stored by the body as fat.

Factors that can lead to obesity are,

  • Increased intake of energy-dense foods that are high in fat and sugars
  • Decrease in physical activity due to the increasingly sedentary nature of work
  • Environmental and societal changes associated with the development
  • Lack of supportive policies in health, agriculture, environment, food processing, and education
  • Diseases – Hypothyroidism, Chronic stress, Insomnia & Hypersomnia
  • Eating Disorders
  • Smoking cessation
  • Drugs

  • Pharmacotherapy

  • Endoscopic treatments

Your doctor may suggest Endoscopic bariatric and metabolic therapies (EBMTs) as a treatment of obesity. There are mainly two options

  • Gastric balloon placement

An intragastric balloon is kept in the stomach to slow down gastric emptying and leads to a feeling of fullness.

  • Endoscopic sleeve gastroplasty (ESG)

Endoscopic sleeve gastroplasty is an option for you if the BMI is 30 or more and other lifestyle modification treatments have failed. ESG is a minimally invasive procedure to facilitate weight loss, a suturing device is introduced into the stomach via the throat, sutures are placed in your stomach to make it smaller.

Surgical Options (bariatric surgery)

  • A laparoscopic adjustable gastric band (LAGB)

This is a laparoscopic surgery to create a small stomach pouch with the help of small incisions in the abdomen. The small stomach pouch makes the patient to experience a feeling of fullness which aids weight loss.

  • Laparoscopic sleeve gastrectomy (LSG)

This is a short, safe laparoscopic surgery to reduce the size of your stomach, the goal of this procedure is to limit the quantity of food taken at one time. In Laparoscopic Sleeve gastrectomy 70% of the stomach is removed and a narrow sleeve is created. This procedure doesn’t involve bypassing or removal of the intestine and hence causes only minimal nutritional disturbances.

  • Biliopancreatic diversion

In this procedure, a banana-shaped stomach tube is created by removing 80% of the stomach. Biliopancreatic diversion is done with or without duodenal switch (BPD-DS) and with or without LSG (ie. staged BPD)

  • Roux-en-Y gastric bypass (RYGB)

Roux-en-Y gastric bypass (RYGB) is also known as bariatric surgery, this is done as a laparoscopic surgery with a minimal abdominal incision. An egg-sized pouch is created in the upper stomach then it is connected to the small intestine, known as the Roux limb. This creates a "Y" shaped connection and the intake of food then bypasses the rest of the stomach and the upper part of the small intestine. The absorption of fat, calories, minerals, and vitamins is reduced by this method to help weight loss.

  • Single Incision Bariatric Surgery

If one wants to avoid multiple incisions and wants a cosmetic outcome, there is an option called Single Incision Laparoscopic Sleeve gastrectomy. Here the surgeon makes only 2-2.5 cm incision within the umbilicus and completes the entire surgery through this incision using specialized instruments, which is done in very few centers apart from Aster Medcity. This option is ideal for young individuals coming up for weight loss surgery.
