Obesity is usually caused by lifestyle habits and underlying medical conditions or risk factors leading to overweight.  

Medical causes of obesity can include:

Hypothyroidism- Condition associated with thyroid gland, located in the neck, produces too little thyroid hormone. This hormone regulates our metabolism. The decrease in levels of these hormones effects the metabolism, leading to weight gain.

Cushing’s syndrome- Condition wherein the adrenal glands secrete an excess amount of cortisol hormone, leading to a build-up of fat in certain sites such as the face, upper back, and abdomen.

Polycystic ovary disease:  This condition leads to increase in levels of androgen levels leading to males like characteristics such as body hair growth, irregular periods and weight gain.   

Depression- People with depression overeat or binge eating ultimately leading to obesity.

Pregnancy- During the pregnancy period women tend to attain weight significantly and most of them find it difficult to lose after the pregnancy. This could lead to obesity.

Other causes

Genetics. Some people are genetically predisposed to the condition.

Family lifestyle. Obesity runs in family, if one or either of your parents are obese then you are a risk of attaining the same. Family members share same lifestyle or eating habits leading to obesity
