Hormonal imbalances can cause underactive thyroid, polycystic ovary syndrome, and Cushing's syndrome. These are all major factors that explain why individuals become overweight and obese.

Cushing's syndrome occurs when too much of the hormone cortisol is produced by the adrenal glands. If an individual takes a certain medicine for a long period of time in high doses, they may also develop Cushing's syndrome. Cushing's syndrome causes people to have fat in the upper body, gain mass, and develop a round face, but thin arms and legs. PCOS affects women around the age of giving birth.
