Obesity is an endocrine and metabolic disease, also known as obesity disorder, mainly caused by excessive accumulation or abnormal distribution of body fat, leading to a chronic metabolic disease. It can result from various factors including genetic and environmental interactions, often characterized by excessive abdominal fat accumulation. Additionally, obesity is closely related to the occurrence of hypertension, coronary heart disease, type II diabetes, dyslipidemia, sleep apnea, cholecystitis, gallstones, osteoarthritis, and more. Therefore, obesity is classified as an endocrine and metabolic disease.

Obesity is classified as a disease.

Obesity is a clinical syndrome characterized by a body mass index (BMI) exceeding normal levels. Generally, obesity with an unclear cause is called simple obesity, or primary obesity, while obesity with a known cause is called secondary obesity. In China, the standards for BMI are as follows: a normal BMI is below 24 kg/m². Being overweight is defined as having a BMI greater than 24 kg/m², mild obesity is greater than 26 kg/m², moderate obesity is greater than 28 kg/m², and severe obesity is greater than 30 kg/m². Therefore, obesity is a metabolic clinical syndrome.

What is obesity?

Obesity is a common group of metabolic syndromes, which occurs when the caloric intake of a human body exceeds its caloric expenditure. The excess calories are then stored in the body in the form of fat. When this amount exceeds normal physiological needs and reaches a certain value, it evolves into obesity. There are many methods for assessing obesity, including anthropometry, dual-energy X-ray absorptiometry, ultrasound, CT, infrared sensing valves, and others. Obesity without a clear pathological cause is referred to as simple obesity, while obesity with a defined pathological cause is referred to as secondary obesity. The causes of obesity are of two types: one is primarily due to excessive diet and insufficient activity, where caloric intake exceeds caloric expenditure; the other is obesity caused by disorders of fat metabolism.

early symptoms of obesity

The early symptoms of obesity mainly include fatigue, poor appetite, somnolence, and a general lack of energy. The treatment for these symptoms fundamentally involves controlling obesity and reducing body weight. Weight control methods primarily include, firstly, dietary control by choosing low-calorie diets, such as a ketogenic low-carbohydrate diet to help reduce weight. The second method involves exercise; if one does not have conditions like diabetes, hypertension, or hyperlipidemia, they can gradually engage in both aerobic and anaerobic exercises within their capacity. The third option, if diet and exercise prove insufficient, is to consider medication. There are now a series of weight loss drugs approved by national safety and the Food and Drug Administration that can be used. Additionally, in cases of severe obesity, metabolic surgery can be considered to alleviate the symptoms of obesity. (Please use medication under the guidance of a professional physician and do not self-medicate.)

Can people with obesity exercise?

Obesity is a metabolic disease caused by excessive accumulation of fat in the body or abnormal distribution, commonly referred to as obesity, with body weight exceeding the standard. Obesity can be due to excessive intake and insufficient exercise; thus, not only can obese individuals exercise, but they also need to persist in it. However, during exercise, it is important to consider special circumstances. The amount and method of exercise vary from person to person, and it is necessary to develop individualized exercise plans and choose exercises or programs that are easy to maintain while progressively advancing. However, when designing exercise treatment plans, it is crucial to consider the impact of complications, especially for patients with cardiovascular, respiratory, or musculoskeletal comorbidities, and choose suitable forms of exercise. Generally, it is recommended to exercise three to five days per week, with 30 to 45 minutes of appropriate activity each day. Patients with these complications should avoid intense exercises and can start with mild activities such as brisk walking, swimming, and strolling, or consult with rehabilitation specialists to develop appropriate individualized exercise plans.

What are the dietary restrictions for obesity?

If it's obesity, it means a body mass index (BMI) greater than 28. In terms of dietary restrictions for obesity, the general principles are low salt and low fat. First and foremost, intake of fats should be limited, including both the cooking oils and foods consumed. Preference should be given to vegetable oils, and consumption of animal fats should be minimized. Even with vegetable oils, there is a limit to how much should be used, as excessive amounts can also exceed health standards. Furthermore, one should eat less fast food and junk food, such as various fried foods or those containing excessive seasonings, and these foods should be consumed minimally. There are also "invisible" fats to consider, such as those found in nut snacks and various small packaged snacks like peanuts and fried beans, which are very high in calories and should be consumed less. Additionally, sugary drinks like iced tea and pear syrup drinks should be avoided. The overall principle is a low-calorie diet, avoiding high-calorie foods.
