Obesity is not just a cosmetic defect; it is a serious metabolic disorder that increases the risk of cardiovascular disease, diabetes and hypertension. Doctors often use body mass index (BMI), which is calculated as the ratio of body weight to the square of height, to diagnose and evaluate obesity. There are several categories of BMI that reflect the degree to which body weight corresponds to height, ranging from underweight to extreme obesity.

Extreme obesity is accompanied by serious health problems, but even a small amount of weight loss can significantly improve a person's health. One of the main symptoms of obesity is being overweight, but a high BMI does not always indicate excess fat storage.

Signs of obesity can include other health problems such as high cholesterol, diabetes, hypertension, and type II diabetes. It is important to see a doctor if you suspect obesity or if overweight problems begin to bother you. Your doctor can help you assess the effects of obesity and develop a strategy for weight loss.

The weight loss process usually involves changing your diet, increasing physical activity and making lifestyle changes. In some cases, weight loss medications or surgical treatment may be prescribed. However, it is important to remember that successful weight loss takes time, persistence and consistency.

While genetics and hormonal factors may play a role in the development of obesity, the underlying cause is often an imbalance between calories consumed and calories expended. A sedentary lifestyle, poor diet, pregnancy, lack of sleep, certain medications and certain medical conditions can contribute to the accumulation of excess weight.

Obesity carries the risk of developing many serious complications, including cardiovascular disease, diabetes, sleep apnea, depression and cancer. Therefore, it is important to take steps to lose weight and maintain a healthy lifestyle.
