What are the 4 stages of obesity?

The stages of obesity are typically categorized based on Body Mass Index (BMI) measurements. These stages help in assessing the severity of obesity and guide appropriate medical intervention. The four stages are:

1. Overweight (Pre-Obesity):

   • BMI: 25.0 - 29.9 kg/m²
   • This stage indicates a weight range that is higher than what is considered healthy but not yet classified as obesity. Individuals at this stage are at increased risk for developing health issues if they gain more weight.

2. Class 1 Obesity (Mild Obesity):

   • BMI: 30.0 - 34.9 kg/m²
   • At this stage, the individual is considered to have obesity. Health risks such as type 2 diabetes, hypertension, and cardiovascular diseases start to become more significant.

3. Class 2 Obesity (Moderate Obesity):

   • BMI: 35.0 - 39.9 kg/m²
   • This stage represents a higher level of obesity with a greater risk for obesity-related health conditions. Medical intervention is often recommended to prevent severe health complications.

4. Class 3 Obesity (Severe or Morbid Obesity):

   • BMI: ≥ 40.0 kg/m²
   • This is the most severe stage of obesity, significantly increasing the risk of serious health problems and mortality. Intensive medical treatment, including potential surgical interventions, is usually considered at this stage to manage the condition effectively.

Each stage of obesity carries progressively higher health risks, and early intervention can help mitigate these risks and improve overall health outcomes.
