BMI introduction

     BMI is a metric used to evaluate a person’s leanness or corpulence based on their height and weight. It is often used as a general indication of a person’s healthy body weight in relation to their height. Specifically, the BMI value produced from the computation is used to classify a person as being underweight, normal weight, overweight, or obese, based on the result’s range. These BMI levels vary by location and age, and are sometimes further subdivided into subcategories such as severely underweight or very obese. Being overweight or underweight may have serious health consequences, and although BMI is an imprecise indication of healthy body weight, it can be used to determine if further testing or action is necessary. The table below details the various BMI categories that the calculator uses.

The dangers of being overweight


Obesity raises the chance of developing a variety of severe illnesses and health problems. According to the Centers for Disease Control and Prevention (CDC), the following hazards exist:

  • Hypertension
  • Increased LDL cholesterol, which is generally regarded as “bad cholesterol,” decreased HDL cholesterol, which is considered “healthy cholesterol in moderation,” and elevated triglycerides
  • Diabetes type II
  • Cardiovascular disease
  • Stroke
  • Gallbladder disease
  • Osteoarthritis is a kind of joint disease
  • characterized by cartilage degradation in the joints.
  • Obstructive sleep apnea and breathing difficulties
  • Certain types of cancer (endometrial, breast, colon, kidney, gallbladder, liver)
  • Low standard of living
    Clinical depression, anxiety, and others are all mental disorders.
  • Pains in the body and difficulties performing specific bodily tasks
  • In general, a higher risk of death compared to individuals with a normal BMI.

         As can be seen from the list above, being overweight may have a variety of unpleasant, and in some instances deadly, consequences. In general, an individual should strive to maintain a BMI of less than 25 kg/m2, but should contact their doctor to decide if they need to make any lifestyle adjustments to improve their health.

The dangers of being underweight

Being underweight carries a number of hazards, which are detailed below:

  • Nutritional deficiency, vitamin deficiency, and anemia (lowered ability to carry blood vessels)
  • Osteoporosis is a condition that weakens the bones and increases the chance of breaking them. Impairment of immunological function Concerns about growth and development, particularly in children and adolescents

  • Additionally, obese women have a greater risk of miscarriage during the first trimester.
  • Complications that may occur as a result of surgery
  • In general, a higher risk of death compared to individuals with a normal BMI.
    In certain circumstances, being underweight may be a symptom of a more serious underlying illness or disease, such as anorexia nervosa, which carries its own set of dangers. Consult your doctor if you believe you or someone you know is underweight, especially if the cause does not appear evident.
