A research team of over 50 doctors and scientists has concluded that obesity is not always a disease. Their findings, published in The Lancet Diabetes & Endocrinology, advocate for a redefinition of obesity and the establishment of new diagnostic criteria. The report also emphasizes the need for comprehensive weight-loss treatments for patients whose health is affected by excess weight.
The report has garnered support from more than 75 professional organizations worldwide, including the American Heart Association, the European Federation of Internal Medicine, and the World Obesity Federation. However, how these recommendations will influence medical practice remains to be seen.
Currently, obesity is typically defined using the Body Mass Index (BMI), calculated by dividing a person's weight in kilograms by the square of their height in meters. In Western countries, a BMI over 30 is generally classified as obese. While BMI is a useful screening tool, the report argues that it is not equivalent to a medical diagnosis. BMI cannot reliably assess an individual's health status. For instance, some individuals with high BMI may be metabolically healthy and experience no significant negative impact on their lives, potentially negating the need for treatment.
The report proposes a paradigm shift by categorizing obesity into two distinct types:
1. Clinical Obesity:
Patients whose weight has caused health issues or significantly impaired daily functioning.
2. Preclinical Obesity:
Patients with excess weight but who, based on blood tests and other evaluations, are otherwise healthy.
The research team suggests that this classification could have a profound impact on medical practice. For patients with clinical obesity, priority should be given to pharmacological or other treatment options. In contrast, those with preclinical obesity, while not currently exhibiting health problems, should be monitored for potential risks. Treatment for these patients may focus on health counseling to reduce future disease risk. Additionally, for individuals with a family history of obesity-related conditions, weight-loss medications might still be a reasonable preventive measure.
This nuanced approach aims to improve care for individuals affected by obesity and better allocate medical resources.
