Understanding body mass index chart?

The body mass index (BMI) is a measure of body weight in relation to height, and it's calculated by dividing the person's weight in kilograms by the square of their height in meters. A high BMI indicates that you're at risk for various health problems like type 2 diabetes, cardiovascular disease, breast cancer, gallstones, and more.

On the other hand. people with lower BMI are at increased risk for osteoporosis. So keep your diet under control! Remember this too- women have smaller bones than men because they have different levels of estrogen so while adults should not let their BMI get below 18 or above 24 there are certain teens who need to stay at 18 or below to avoid becoming obese). 

A body mass index chart is a graphical comparison of an individual’s height and weight. It also takes into account the sex of the person to generate a number that helps approximate their body fat percentage. BMI is the ratio of height to weight (weight in kilograms divided by height in meters squared). A person's BMI is considered "overweight" when the number falls between 25 and 29; "obese" when it exceeds 30. 

Maintaining a healthy body weight is associated with length of life and the prevention of chronic illness. Excessive weight is associated with increased risk for heart disease, high blood pressure, high cholesterol levels, type 2 diabetes, gallstones, and certain cancers. A general rule of thumb is that if you have been maintaining your current body weight or losing more than two pounds per week on most diets for two months without any signs that your weight is stable at a lower level then it is time to go on a different diet program to avoid excessive loss rates.

Body Mass Index or BMI is the weight in kilograms divided by the square of his height in meters. Using this chart, you can determine how close your BMI is to being overweight. If your body mass index is 25-29.9, you are overweight. If it falls between 30-39.9, you are obese and if it falls at 40 or over, then you have morbid obesity, which is an extreme increase in body fat with the potential of leading to health complications down the line due to excess carrying of food weight on your frame."

The body mass index chart ranges from underweight to morbidly obese. It is based on the same number line as height, so you can see how weight increases at different heights. Although it is not an accurate measure of fatness due to body composition discrepancies, if your BMI is between 18.5 and 24.9 then you are a generally healthy weight for that height classification.

BMI Chart, which is also called the Quetelet Body Mass Index chart, was created by the Belgian scientist Adolphe Quetelet in 1832. It can be used to measure relative weight under idealized conditions for height for various populations. But it has been criticized as an appropriate measure of obesity because it does not take into account variations in body fat distributions (android versus gynoid). The BMI is defined as one's weight divided by their height squared, or generally written as kg/m2.

This chart is very accurate, but it’s difficult to find a BMI that fits your situation. Most people fall between 23-27.5 for Women and 27-30 for Men. But if you are research shows you are an athlete with low body fat, or someone who has gained weight due to metabolic syndrome, chronic conditions or pregnancy - the BMI will not be accurate enough.

It's important to know what's happening with your weight so you can have a better understanding of how much excess fat blood sugar levels have on how you feel every day just by looking at the mirror. The BMI chart below can be used to find a healthy body weight. If your height and weight don't match the closest standard height and weight, adjust the height and weight until they align with one of the symbols. Height should be measured in feet and inches (preferred) or simply in centimeters (feet?3; x 0.0254 = meters; pounds/inches?2; x 0.0254= kilograms).

A lot of people who don't have good diets tend to be heavier. When you're heavy, your hormone levels are often imbalanced, which can cause you to stop producing enough insulin or produce too much for the body's needs. That can lead to type 2 diabetes  if left untreated  and is one reason why it might seem like people who eat junk food age faster than those with healthy appetites."  What is BMI? BMI stands for Body Mass Index; it's used as an indication of total body fatness for most men and women above 20 years old (this varies).

The BMI chart was originally created to classify people in various ranges of weight. There are many different variations of the classification chart. They were not specifically designed for athletes, although an athlete weighing 200 lbs would be considered overweight by some calculations, while others would consider them healthy.

Yellowing

Yellow Eyes and Skin Symptoms: Causes, Warning Signs and When to Seek Care

Yellowing of the eyes and skin is one of the most noticeable physical changes a person can experience. Often referred to as jaundice, this symptom is not a disease by itself but a sign of underlying health conditions. Understanding yellow eyes and skin symptoms is essential because they frequently indicate problems involving the liver, blood or bile ducts and may require urgent medical attention.

In India, jaundice is a common presentation across age groups due to infections, liver disease and metabolic disorders.

 

What Does Yellowing of Eyes and Skin Mean?

The yellow colour appears due to excess bilirubin in the blood.

Bilirubin is:

  • a yellow pigment

  • produced from the breakdown of red blood cells

  • processed and removed by the liver

When bilirubin builds up, it deposits in tissues, causing yellow discoloration.

 

Why the Eyes Turn Yellow First

The sclera, or white part of the eyes, contains elastic tissue that binds bilirubin easily.

This makes yellowing:

  • more visible in eyes

  • detectable before skin changes

Yellow eyes are often the earliest sign of jaundice.

 

Common Causes of Yellow Eyes and Skin

Liver-Related Causes

The liver plays a central role in bilirubin metabolism.

Common liver causes include:

  • viral hepatitis (A, B, C, E)

  • fatty liver disease

  • alcoholic liver disease

  • liver cirrhosis

  • drug-induced liver injury

ICMR reports viral hepatitis as a major cause of jaundice in India.

 

Bile Duct Obstruction

Blocked bile flow prevents bilirubin excretion.

Causes include:

  • gallstones

  • bile duct strictures

  • pancreatic or bile duct tumours

This type of jaundice is often associated with itching and pale stools.

 

Blood Disorders

Excess breakdown of red blood cells increases bilirubin production.

Conditions include:

  • hemolytic anemia

  • malaria

  • inherited blood disorders

The liver may be overwhelmed despite being healthy.

 

Infections

Certain infections directly affect liver function.

Examples include:

  • hepatitis viruses

  • leptospirosis

  • severe sepsis

WHO data highlights hepatitis as a leading infectious cause of jaundice globally.

 

Newborn and Pregnancy-Related Causes

While common in newborns, jaundice in adults always needs evaluation.

Pregnancy-related liver disorders can also cause yellowing.

 

Associated Symptoms That Provide Clues

Yellow eyes and skin are often accompanied by:

  • dark yellow or tea-coloured urine

  • pale or clay-coloured stools

  • itching

  • fatigue

  • abdominal pain

  • loss of appetite

These symptoms help identify the underlying cause.

 

When Yellowing Becomes Dangerous

Seek urgent medical care if yellowing is accompanied by:

  • high fever

  • severe abdominal pain

  • confusion or drowsiness

  • vomiting

  • rapid worsening of colour

These signs suggest severe liver or systemic disease.

 

Jaundice and Liver Function

The liver normally:

  • conjugates bilirubin

  • excretes it into bile

When liver cells are damaged, bilirubin accumulates.

Lancet studies confirm jaundice as a key marker of liver dysfunction.

 

Diagnostic Evaluation

Doctors evaluate jaundice using:

  • blood tests for bilirubin levels

  • liver function tests

  • viral markers

  • ultrasound or CT scans

  • additional tests based on findings

Early testing identifies reversible causes.

 

Impact on Daily Life

Persistent jaundice can affect:

  • energy levels

  • digestion

  • mental clarity

  • work performance

Untreated liver disease can progress silently.

 

Treatment Depends on the Cause

There is no single treatment for jaundice.

Management focuses on:

  • treating infection

  • relieving bile obstruction

  • stopping harmful medications

  • managing chronic liver disease

Self-medication can worsen liver injury.

 

Role of Preventive Healthcare

Preventive measures include:

  • hepatitis vaccination

  • safe drinking water

  • limiting alcohol intake

  • regular health checkups

NITI Aayog emphasises liver health in preventive care strategies.

 

Lifestyle Factors That Affect Liver Health

Risk factors include:

  • excessive alcohol

  • obesity

  • high-fat diets

  • unsafe injections

Addressing these reduces jaundice risk.

 

Importance of Early Detection

Early diagnosis:

  • prevents complications

  • improves recovery

  • reduces hospitalisation

Delays increase the risk of liver failure.

 

Jaundice Is a Symptom, Not a Diagnosis

Understanding this distinction is crucial.

Treating the symptom alone:

  • does not resolve the disease

  • may mask serious conditions

Medical evaluation is essential.

 

Conclusion

Yellow eyes and skin symptoms are visible warning signs that should never be ignored. Most often linked to jaundice, they reflect underlying problems involving the liver, bile ducts or blood. Early medical evaluation, accurate diagnosis and timely treatment are critical to prevent serious complications. Recognising these symptoms and seeking care promptly can protect liver health and save lives.
