What is obesity? What are the types?

Obesity is a relatively common phenomenon, and we often encounter obese patients in our daily lives. This not only affects the physical health of patients but also impacts their psychology, making them more self-conscious and lacking confidence. So, what exactly is obesity? And how is obesity classified clinically?

What is Obesity?

1. Definition of Obesity

Obesity refers to a state where the human body exhibits significant overweight and excessive fat accumulation, particularly due to the excessive buildup of fat, especially triglycerides, in the body. In most cases, obesity occurs as a result of excessive food intake or changes in the body's metabolism, leading to an excessive accumulation of fat and an increase in body weight. Clinically, obesity is a relatively common disease.

2. Simple Obesity

Simple obesity refers to an increase in the size and number of fat cells in the body, resulting in an abnormal increase in the percentage of body fat. Some patients may also experience excessive local fat deposition. Generally, the fat distribution in simple obesity patients is relatively uniform, without endocrine disorders or metabolic diseases. However, simple obesity has a certain genetic factor, and most patients have a family history of obesity.

3. Secondary Obesity

Secondary obesity is usually caused by a certain disease, particularly those related to the nervous and endocrine systems, accounting for 5% of all diseases. In most cases, patients with secondary obesity are overweight from a young age but do not have a hereditary or familial disease, which is referred to as secondary disease.
