What is Morbid Obesity?

Obesity is considered a health "condition". A person is considered "obese" when he or she weighs 20% or more than his or her ideal body weight. At that point, the person's weight poses a real health risk. Obesity becomes "morbid" when it significantly increased the risk of one or more obesity related health conditions or serious diseases. Morbid obesity - sometimes called "clinically severe obesity" - is defined as having a Body Mass Index (BMI) of 35 or higher.

What is BMI ?

To understand Morbid Obesity we have to know the Body Mass Index (BMI). Body Mass Index is a simple and widely used method for estimating body fat mass. It calculates body fat based on the relationship of weight and height.

The formula for calculating Obesity Body Mass Index (BMI) is :

BMI = Weight (in Kgs) / Height2 (in Metres)


A Healthy BMI is about 18-25.

* BMI Less than 19 indicates you are Under Weight.

* BMI between 20 and 24 is usually considered Normal.

* BMI of 25 to 29 is considered Over Weight.

* BMI of 30 or above is considered Obese.


How to calculate Normal Weight ?

Weight = Height (in cms) - 100

[example : 176cms - 100 = 76 Kg]

where 76 Kg is the normal weight required for a person whose height is 176cms.


Who will benefit from Bariatric Surgery ?

People with Diabetes Mellitus, Heart Disease, High Blood Pressure, High Blood Cholesterol, Asthma, Respiratory Insufficiency, Sleep Apnea Syndrome, Gastroesophageal Reflux Disease, Gallbladder Disease, Stress Urinary Incontinence, Low Back Pain, Degenerative Disk Disease & Degenerative Joint Disease.
