Maintaining a healthy body weight is one of the key indicators of a healthy lifestyle. The simplest reference standard is the Body Mass Index (BMI). A BMI above the normal range indicates being overweight, meaning the body has accumulated excess fat, which increases the risk of developing a variety of health problems such as type 2 diabetes, high blood pressure, high cholesterol, gout, fatty liver, kidney failure, heart disease, heart failure, stroke, joint degeneration, infertility, and certain cancers. Taking early action to manage obesity is essential for maintaining good health.

How overweight is “too overweight”?

According to Asian body composition standards, a BMI of 23–25 is considered “overweight.” If you already have conditions such as fatty liver, diabetes, hypertension, or hyperlipidemia, weight control should begin immediately. When BMI exceeds 25, it falls into the “obese” category; if it goes above 27, it meets the clinical diagnosis of obesity, which requires early management. Delaying intervention not only harms health but can also make future treatment more difficult.

 

Is losing weight just about eating less and exercising more? Why use weight loss injections?

Because every person’s body composition and causes of weight gain vary, weight management must be personalized. For some people, metabolic or hormonal factors may prevent them from reaching their target weight through diet and exercise alone. That’s why the first step in weight management should always be a comprehensive medical evaluation. A doctor can assess the severity and underlying causes of obesity, tailor a customized plan, and closely monitor progress to help you lose weight effectively and safely.
With advances in modern medicine, weight loss injections have become one of the most revolutionary tools for weight management today.

A3: They are not suitable for pregnant or breastfeeding women, anyone allergic to the ingredients, or people with a personal or family history of medullary thyroid carcinoma, multiple endocrine neoplasia syndrome, pancreatitis, severe gastrointestinal disorders, or impaired kidney function.

 

Q4: How can I choose the most suitable type of weight loss injection?
A4: The best approach is to consult a qualified doctor. Your doctor will recommend the most appropriate treatment plan based on your BMI, health conditions, medical history, weight-loss goals, preferred injection frequency, and budget.
