What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a tool used to measure a person’s weight based on their height. It provides a simple way to estimate body fat levels and helps evaluate health risks associated with body weight.
To calculate BMI, use this formula:
For example, if a person weighs 70 kg and has a height of 1.75 meters:
BMI = 70/ 1.752
= 70/3.0625
=22.86
Moreover, BMI should not be used to assess children or teenagers. Consult a pediatric specialist to assess a child’s growth and weight properly.
Why is Body Mass Index (BMI) Important?
Body Mass Index is essential because it helps identify the body’s fat level and can signal potential health risks. Both low and high body fat can lead to various chronic diseases. Low BMI (underweight) results from malnutrition and increases the risk of conditions like anemia, osteoporosis, and a weakened immune system. On the other hand, a high BMI (overweight or obese) raises the risk of serious health issues like stroke, type 2 diabetes, and heart disease.
Keeping a healthy Body Mass Index is vital for staying well and reducing the risk of these health issues.
Impact of High BMI on Health
When your Body Mass Index is 25 or higher, it is associated with an increased risk of chronic health problems, including:
- Cardiovascular Diseases: A BMI of 25 to 29.9 (overweight) and 30 or above (obesity) increase the possibility of developing high blood pressure, heart disease, and stroke.
- Diabetes: Obesity raises the risk of developing type 2 diabetes. People with a BMI over 30 are more likely to have insulin resistance, leading to higher blood sugar levels.
- Cancer: Research shows that obesity can increase the chance of cancers like colon, breast, and endometrial.
Health Risks of Low BMI
People with a low Body Mass Index (BMI under 18.5) are also at risk for several health issues, including:
- Anaemia
- Infertility
- Low Immunity
- Osteoporosis
How to Calculate Your BMI?
There are two common ways to calculate Body Mass Index:
Method 1: Using pounds and inches
- Multiply your weight (in pounds) by 703.
- Divide the result by your height (in inches).
- Divide the result by your height again.
Method 2: Using kilograms and meters
Take your weight in kilograms and multiply it by your height in meters, then square the height.
For example, if a person weighs 65 kg and has a height of 1.75 m, their BMI will be:
BMI = 65 x 1.7562 = 21
Preventive Measures and Lifestyle Changes for Maintaining a Healthy BMI
To maintain a healthy BMI and reduce the risk of chronic diseases, try making these lifestyle changes:
- Regular Exercise: Try to get at least 150 minutes of moderate exercise each week. Staying active helps manage or lower body weight.
- Balanced Diet: Eat a diet full of fruits, vegetables, whole grains, and lean proteins. This helps manage weight and promotes overall health.
- Regular Health Screenings: Schedule routine check-ups to monitor your BMI and detect early signs of chronic diseases.
The Relationship Between BMI, Chronic Diseases, and Health Insurance
Maintaining a healthy Body Mass Index is necessary for both your overall health and health insurance considerations. Health insurers consider BMI when deciding premiums since a higher BMI can indicate a greater risk of chronic diseases and higher insurance costs.
Before purchasing a health insurance policy, it is important to calculate your BMI and understand its implications for your health and insurance coverage. Tools like the Star Health BMI calculator can help you do this accurately.
Final Thoughts
Understanding Body Mass Index (BMI) is essential for maintaining good health and lowering the risks of chronic diseases. Keeping a healthy BMI can improve overall health, help you make informed health insurance decisions, and prevent future health issues.
