First, I recommend visiting the Department of Endocrinology and Metabolic Science, because obesity itself is a metabolic disease, and now obesity is divided into simple obesity and secondary obesity.

Simple obesity refers to weight gain caused solely by factors such as irregular eating habits, unscientific diet, and lack of exercise, without other underlying causes.

There is also a type called secondary obesity, which is attributable to identifiable causes. For example, a common disorder in endocrinology known as Cushing's syndrome is caused by problems in the pituitary or adrenal glands, leading to an excessive secretion of cortisol in the blood. This results in the redistribution of fat and subsequent weight gain. Another example is hypothyroidism, which also causes weight gain.

Therefore, it is essential to see an endocrinologist, who can determine based on clinical manifestations and actual conditions whether the obesity is simple or secondary, and then provide appropriate treatment.
