What is BMI?
Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in meters squared. It is used as a screening tool to identify potential weight problems in adults. It provides a rough estimate of body fat and can help gauge whether your weight is in a healthy range for your height.
Standard BMI Categories
The World Health Organization (WHO) defines the following standard BMI categories for adults:
- Severely Underweight: Less than 16.5
- Underweight: 16.5 to 18.4
- Normal weight: 18.5 to 24.9
- Overweight: 25 to 29.9
- Obesity Class I: 30 to 34.9
- Obesity Class II: 35 to 39.9
- Obesity Class III: 40 or greater
It's important to note that BMI does not account for factors like body composition (muscle vs. fat), age, or sex. However, it is a useful starting point for assessing weight-related health risks.
Understanding Anorexia Nervosa
Anorexia nervosa is a serious, potentially life-threatening eating disorder characterized by an abnormally low body weight, an intense fear of gaining weight, and a distorted perception of weight. People with anorexia place a high value on controlling their weight and shape, using extreme efforts that tend to significantly interfere with their lives.
While a very low BMI (often below 17.5, or below 15 in extreme cases) is a key diagnostic criterion, it is not the only one. The condition also involves severe psychological and behavioral components.
Common Signs and Symptoms of Anorexia:
- Extreme weight loss or not making expected developmental weight gains.
- Distorted body image and intense fear of gaining weight.
- Severe restriction of food intake.
- Preoccupation with food, calories, fat grams, and dieting.
- Denial of the seriousness of low body weight.
- Physical symptoms like fatigue, dizziness, hair thinning, and feeling cold.
