Questions and Answers

Obesity is a serious health problem.

Obesity can be defined as excess body fat that is harmful to health. Obesity occurs when the body consumes more than it burns. However, the cause is often complex and goes beyond diet.

Obesity Measurement

BMI (Body Mass Index) is the most commonly used tool.

BMI 18-49 – Healthy Weight
BMI 25-29.9 – Overweight
BMI of 30 or higher – Obese
BMI of 40 or higher – severe/morbid obesity

BMI is not without limitations, despite its widespread use. The BMI does not take into account muscle mass, fat distribution, or body composition. Some other useful measures are:

Measure your waist circumference.
Waist-to-hip ratio
Body Fat Percentage

Redefining Obesity

The experts are increasingly referring to obesity as a Chronic Disease that is marked by metabolic problems, inflammation, and long-term risks.

Obesity: Causes and Effects

The cause of obesity is not a singular one. The result is a complicated interaction between biology, behaviour, and the environment.

1. Unbalanced Energy

It is easy to understand that fat accumulation occurs when you consume more calories than your body can use. Despite similar diets, not all people gain weight the same way, indicating that there are other factors at work.

2. Genetic and biological factors

The genes can affect the way your body burns and stores energy.
The hormones insulin, cortisol, and leptin affect hunger and fat accumulation.
Risk is increased by certain medical conditions, such as hypothyroidism and Cushing’s Syndrome.

3. Lifestyle and Behaviour

Sugar, processed carbs, and refined carbohydrates are high-sugar diets.
Sitting for long periods of time without any physical exercise.
Stress and irregular sleep patterns.

4. Medicines

Weight gain can be a side effect of some drugs, such as antidepressants and steroids.

5. Environment and Society

Fast food, sugary drinks, and easy access are all available.
Exercise in the city is limited.
Schedules of work that limit sleep and physical activity.
Food habits and cultural practices in families.

Obesity and Health Risks

The risk of chronic diseases, including some that are life-threatening, increases with obesity.

Metabolism and cardiovascular risks

Type 2 Diabetes
Blood pressure
Heart Disease and Stroke
Cholesterol levels high

Additional Health Problems

Breast, colon, and endometrial cancer are all included in this list.
Breathing problems and sleep apnea
Fat liver disease
Joint problems and osteoarthritis

Obesity Treatment Options

Treatment of obesity is long-term and comprehensive. Fast fixes are rarely effective.

Physical Activity: 150 minutes per week of moderate intensity exercise.
Behavioral Therapy. Self-monitoring. Setting realistic goals. Stress management.
Support: Working with dietitians or therapists.

2. Medicines

Doctors may prescribe weight-loss medicines if lifestyle changes aren’t enough. They can help:

Fat absorption
Insulin sensitivity can be improved

Orlistat, semaglutide, and liraglutide are some examples. For best results, medications are often combined with exercise and diet.

3. Bariatric Surgery

Surgery can help people who have severe obesity and obesity-related problems. There are several types of surgery.

The Gastric Bypass is a procedure that reduces the size of your stomach and redirects digestion.
Sleeve Gastrectomy: removal of part of the stomach.
Gastric Banding uses a band in order to restrict food consumption.

After surgery, you will need to make lifestyle changes and follow up for the rest of your life.
