Obesity is not something that occurs overnight. People start to gain weight due to overeating, poor diet and lack of physical exercise over a long period of time. Still, there are certain medical causes that lead to obesity. Some medical conditions trigger obsesity without the person changing their diet and lifestyle habits.

So it's best for people who are suffering from obesity to take it seriously. It is necessary for them to get a physical examination and have tests for diagnosing or refuting the presence of a disease that may be the possible causes of obesity. Medical experts know that weight gain can be a result from certain body disorders and diseases that makes it difficult for the individual not to gain weight. Still, there are also certain genetic factors that may lead to obesity in combination with a disease.

There are 3 common medical conditions that can cause obesity in people. These are:

Cushing's syndrome:

This medical condition is caused by an increase in the levels of Cortisol, a steroid hormone. People suffering from Cushing's syndrome gain weight particularly in the upper back and lower back. Their face is also affected.

This condition occurs when excess Cortisol is secreted in the body, because of dysfunction of the adrenal glands or because of taking a Glucocorticoid medication. This condition can also be caused by tumors that increase the secretion of this specific hormone.


Hypothyroidism slows down the metabolic rate of an individual. This condition occurs in patients who thyroid gland is underactive and has decreased hormone production. This causes obesity in almost all cases, as fat is stored in the body instead of being used up in the form of energy. Patients that suffer from severe hypothyroidism are much more likely to suffer than obesity than others. Apart from gaining weight, they get a bloated appearance, especially in the face area and in the area around their eyes.

Polycystic Ovarian Syndrome:

Women, who suffer from polycystic ovarian syndrome, end up with increased secretion of the male hormone Androgen. In turn the production of eggs in the ovaries is affected and they develop into cysts. This causes irregular menstrual cycles in females. This may also cause obesity. If this condition is left untreated, it can also lead to infection and many other medical complications.

Although any of these medical conditions could have the primary causes of your obesity, it is most important to get a good diet and exercise plan.
