Obesity is defined by body mass index (BMI). It is a medical condition in which the excess body fat accumulates to the extent that it can have negative effect on health, leading to a reduced life expectancy and several health problems. However, weight loss surgery is recommended if you cannot lose weight and are keeping it off by maintaining a healthy diet, and lifestyle.
Excess body fat around the tummy and waist can cause functional problems as well as morbid ailments. Treatment includes Tummy Tuck (Abdominoplasty) Flattening of the abdomen by removal of excess fat and/or skin.
Doctors often use BMI and other health conditions like Type 2 diabetes and high blood pressure to determine who are the patients who are likely to benefit from weight loss surgery. The patients who are the right candidates for surgery are those with a BMI>32.5 kg/m2; those who are suffering from co-morbidities like diabetes; or patients with BMI>37.5kg/m2 (with or without associated co-morbidities).
What is Body Mass Index & How Its Calculated
The BMI is a statistical measurement derived from your height & weight. It is considered to be a useful way to estimate healthy body weight fat. It is calculated by the following formula:
BMI = Weight (in Kilograms) / Height (in m.) X Height (in m.)
If your Body Mass Index (BMI) is between 25 and 29.9, you are considered overweight. If your BMI is 30 or over you are considered obese.
|18.5 - 23.5
|23.5 - 27.5
|27.5 - 37.5

Causes of Obesity
- Genetics: Genetics are responsible for affecting hormones in fat regulation. A person is more likely to be obese if one or both parents are obese.
- Lack of Caloric Balance: If you are eating more calories than your body is using, there is a possibility that the extra calories get stored and you can gain weight.
- An Inactive Lifestyle: Lack of physical exercise and involvement in leisure activites like television and computers as well as mechanization of jobs is also developing obesity.
- Our environment: Easily available processed and unhealthy foods, and oversized food portions increases the chances of obesity.
- Medications: Few medications associated with weight gain include antidepressants,anticonvulsants, diabetes medications, steroids, and some high blood pressure medications and antihistamines.
- Psychological factors: Factors like emotional stress, anger, sadness can also lead to weight gain, as people tend to eat more during such conditions.
- Diseases: Conditions like hypothyroidism, insulin resistance, polycystic ovary syndrome, and Cushing's syndrome also contribute to obesity.
What is Morbid Obesity
Those people who are morbidly obese are at a greater risk of illnesses like diabetes, high blood pressure, sleep apnea, gastroesophageal reflux disease (GERD), gallstones, osteoarthritis, heart disease, infertility and cancer. Morbid obesity is a state of severe obesity and is defined by the following condition:
- If a person has a BMI above 37.5 with or without associated illness or BMI above 32.5 with diseases like diabetes, hypertension are considered to be morbidly obese.
Common Obesity Related Conditions
- Type 2 diabetes
- High blood pressure
- Heart disease
- Joint pains/ Osteoarthritis
- Gastroesophageal reflux disease
- Gallstone disease
- Increased chances of developing cancer of breast, prostate,colon, uterus and ovaries.
- Sleeping disorders like Obstructive sleep apnea
- Infertility/Polycystic Ovarian Disease (PCOD)
- Depression/Anxiety/low self esteem
Link Between Obesity and Diabetes
What is Obesity?
An obese person has accumulated so much body fat that it might have a negative effect on their health. If a person’s body weight is at least 20% higher than it should be, he or she is considered obese. Obesity can in turn lead to complications like Diabetes, Hypertension, High Cholesterol, and Obstructive Sleep Apnea & Osteoarthritis.
Is there a link between Obesity and Diabetes?
Of the people diagnosed with type 2 diabetes, about 80 to 90% are also diagnosed as obese. This fact provides an interesting clue to the link between diabetes and obesity. Understanding what causes the disease will hopefully allow us to prevent diabetes in the future.
Being overweight places extra stress on your body in a variety of ways, including your body’s ability to maintain proper blood glucose levels. In fact, being overweight can cause your body to become resistant to insulin. If you already have diabetes, this means you will need to take even more insulin to get sugar into your cells. And if you don’t have diabetes, the prolonged effects of the insulin resistance can eventually cause you to develop the disease.
Indians are genetically susceptible to weight accumulation, especially around the waist. An obese individual is much more susceptible to diseases like diabetes, hypertension, osteoarthritis and obstructive sleep apnoea. Studies have shown that:
- In MALES, Compared with a healthy weight man, an obese man is 5 times more likely to develop type 2 diabetes.
- In FEMALES, An obese woman, compared with a healthy weight woman, is almost 13 times more likely to develop type 2 diabetes.
The traditional approach to treat TYPE 2 DM (Diabetes Mellitus) has been step wise introduction of lifestyle changes with or without oral medications, saving the insulin therapy for last. Treatment should focus equally on remission of both diabetes and obesity and needs to be widely understood. In the light of escalating global diabetes crisis, the need of the hour is to identify interventions that provide a long term metabolic outcome (obesity and associated diseases remission).
There are several methods for treating obesity, such as lifestyle changes encompassing behaviour modification, physical activity, diet modification and medical management. It has been seen that the sustained weight loss is achieved by only 10% of the population.
Bariatric surgery (Obesity surgery) is the most effective long-term treatment for obesity with the greatest chances for amelioration and even resolution of obesity-associated diseases. In the given scenario of increasing morbidity and mortality due to Type II Diabetes Mellitus and obesity, bariatric surgeries emerged as a promising treatment. It provides exceptional sustained weight loss and remission of type II diabetes in addition to improvement in other co-morbidities and quality of life.
What are the Treatment Options for Obesity?
The various treatment options available for obesity are as follows:
Diet and Exercise: If BMI >23.5, certain lifestyle modifications, changes in diet, increase in physical activities, and practicing healthy eating habits can reduce obesity.
Weight loss drugs: If BMI > 27.5 with co-morbidities or >30 with or without co-morbidities, pharmacotherapy with weight loss drugs is reecommended. Close medical monitoring is required while taking a prescribed weight-loss medications.
Surgery: If BMI >32.5 with co-morbidities or >37.5 with or without co-morbidities, bariatric surgery is the right choice of treatment. Weight loss surgery for obesity may be considered if other methods to lose weight have not worked.
Types of Bariatric and Metabolic Surgery
Bariatric surgery is considered to be the most effective treatment for obesity. The bariatric surgical procedures causes weight loss by restricting the amount of food, causing mal-absorption of nutrients, or a combination of gastric restriction and mal-absorption. Most weight loss surgeries are performed using minimal invasive techniques (laparoscopic surgery).
The choice of the surgical procedure depends on the treating surgeon and the team after evaluation and counselling. Common Bariatric surgery options which are available are:
What is Liposuction
Body sculpting through removal of fat from localised areas of the body.
- Ultrasound-assisted lipoplasty (UAL)
- Power-assisted lipoplasty (PAL)
- Superwet and tumescent techniques
Max Institute of Aesthetic and Reconstructive Surgery is the pioneer in using breakthrough technology, VASER LipoSelection.
VASER LipoSelection is a minimally invasive procedure that precisely and efficiently removes unwanted body fat. An alternative to the harsh techniques of traditional liposuction surgery, VASER LipoSelection uses state-of-the-art ultrasound technology designed to gently reshape your body. What distinguishes the LipoSelection procedure is its ability to differentiate targeted fat from other important tissues - such as nerves, blood vessels and connective tissue.
