Obesity, also known as adiposity, is a chronic metabolic disease caused by excessive accumulation of fat or abnormal fat distribution in the body. Therefore, once obesity is diagnosed, it is necessary to conduct tests related to metabolism, such as blood glucose, blood lipids, blood pressure, and blood uric acid, which are commonly known as the "four highs" tests. Additionally, liver function tests and kidney function tests should be completed to exclude obesity caused by other diseases. It is also necessary to conduct examinations for pituitary tumors, adrenal cortex function, and thyroid function to determine whether the obesity is secondary to other diseases.
