 With the trend of sedentary lifestyle ever increasing in this world, the problem of excessive weight is taking a heavy toll on health of people. Weight reduction is a dream of millions of individuals living on this planet.
What is obesity?
Technically obesity is defined as waist hip ratio more than 0.95 for men and 0.8 for women. It roughly corresponds to a BMI of more than 30.

Causes of obesity

Sedentary life style is the most important cause of obesity. Carbohydrate and fat rich diet (fast foods) intake without proper workout leads to fat deposition which causes obesity. There may be other causes of obesity like
1.      Genetic- Prader-willi syndrome, leptin resistance.
2.      Endocrine- Cushing syndrome, hypothyroidism, PCOD.
3.      Drugs-anti-psychotics, mood stablizers and antidepressants.
Health problems caused by obesity
1.      Heart-coronary artery disease, congestive heart failure.
2.      Vascular -hypertension, stroke
3.      Respiratory-obstructive sleep apnea syndrome
4.      Liver- stones in gall bladder.
5.      Cancers
6.      Renal vein thrombosis
7.      Osteoarthritis
8.      Diabetes
9.      Depression

Treatment of obesity

Diet- restriction of carbohydrates and fats in diet is equally important. Both can lead to inflated waists. Exchanging them for fibrous or protein full diet is a good idea. Atkins diet is useful but should be used if other dietary interventions fail.
Exercise- all types of workouts are important but the most useful are cycling and swimming.
A combination of both is the most useful methods of weight loss.
For severe form of obesity called morbid obesity medicines including sibutramine, orlistat, rimonabant and amphetamines are helpful but should be used with caution.
Likewise surgery is only the last resort used only in severe resistant cases. Surgical gastric bypass, bariatric surgery is used in these cases.
