(1) Simple Obesity: Also known as primary obesity, it is the most common type of obesity and accounts for about 95% of obese people.
The main causes: The family often has a history of obesity, mainly caused by genetic factors and excess nutrients.
Symptoms: The body fat distribution of this group of people is relatively uniform, there is no endocrine disorder, and no metabolic disorders. The so-called "middle-aged obesity" belongs to simple obesity.
A. Constitutional obesity: When you are young (mostly until the age of 25), you don’t pay attention to diet control, excess nutrition, and due to genetic factors.
B. Acquired obesity: also known as exogenous obesity, due to excess nutrition from 20 to 25 years old, resulting in increased fat cell volume. Many people do not pay attention to diet control after middle age, and the body begins to deform and lose weight. This is the reason.
Â
(2) Secondary obesity: also known as pathological obesity, mostly caused by a disease in the body, is rare in clinical practice and accounts for only 5% or less of the entire obese population.
The main cause: Obesity is caused by disorders of the endocrine and metabolic balance.
Symptoms: Obesity is only one of the important symptoms of this type of patients, there will be other various clinical manifestations, such as hypercortisolism, hypothyroidism, pancreatic β-cell tumor, hypogonadism, polycystic ovary Syndrome, skull plate proliferation and so on. In fact, physiological obesity and pathological obesity can be transformed into one another. Physiological obesity further causes pathological changes and becomes pathological obesity; pathological obesity can be converted to physiological obesity after treatment. Gradually return to normal physical condition. The common types of pathological obesity are:
* Cushing syndrome*
Cause: Adrenocortical hyperfunction, excessive cortisol secretion
Phenomenon: The face, neck and body are hypertrophic, but the extremities are not very fat.
* Pancreatic *
Cause: Excessive insulin secretion, reduced metabolic rate, reduced fat breakdown and increased synthesis
Phenomenon: Systemic obesity
* Reduced sexual function*
Cause: Cerebral obesity, accompanied by loss of sexual function, or loss of libido.
Phenomenon: Breast, lower abdomen, obesity near genitalia
* Pituitary *
Cause: Pituitary lesions cause excessive secretion of growth hormone in the anterior pituitary
Phenomenon: Whole body bone, soft tissue, visceral tissue hyperplasia and hypertrophy.
* Hypothyroidism *
Cause: Hypothyroidism
Phenomenon: Obesity and mucinous edema

(3) Obesity caused by drugs:
While some medicines effectively treat certain diseases, they also have side effects that make the body fat. For example, the use of adrenocortical hormone drugs for the treatment of allergic diseases, rheumatism, rheumatism, asthma, etc., but also easy to make patients with endocrine disorders, causing obesity. Obese patients account for about 2% of obese people. Under normal circumstances, as long as the use of these drugs is stopped, the obesity situation is expected to improve on its own. Unfortunately, some patients have become "refractory obesity" patients since then.

☆What is the relationship between fat cells and fat?
The formation of obesity is directly related to fat cells in the human body. The body's fat cells are composed of cell membranes, cell nuclei, mitochondrial lipid droplets, and enzymes. Lipid droplets occupy a considerable proportion, and their size controls almost the size of the entire fat cell. Under normal circumstances, the body has a large number of aging fat cells that regenerate each day, but under the influence of metabolism, the total number of fat cells always maintains a dynamic balance. When the organism has excess nutrients or a lack of nutrition, or genetic defects and lipid metabolism disorders, the fat synthesis rate is greater than the decomposition rate, the lipid droplets increase, the fat cell volume also increases, and the body begins to gain weight.

☆ Nutrition deficiency and obesity
Science has confirmed that the lack of certain nutrients in the human body also makes one fat. In the process of energy metabolism and fat conversion to energy release and consumption, the body needs the participation of various nutrients such as B vitamins, iron, calcium and zinc. These nutrients are abundant in vegetables, fruits, and whole grains. If they are insufficiently consumed, they will affect energy conversion and metabolism, resulting in excess energy in the body, excessive fat storage, and consumption of too little fat. Therefore, lack of nutrition can also lead to obesity. If a person suffers from a prolonged partial eclipse picky eaters, excessively fine foods, abuse of oral liquids for nutrition, or improper weight-loss diets, it can lead to insufficient intake of certain nutrients, causing obesity-individual obesity.
