Body temperature is a vital sign that indicates the body's ability to produce and dissipate heat. A normal body temperature for a healthy adult is around 98.6°F (37°C), but it can vary slightly depending on factors such as time of day, activity level, and individual differences. In this guide, we will discuss the causes, symptoms, and prevention of abnormal body temperature.

Causes of abnormal body temperature:

  • Fever: The most common cause of abnormal body temperature is a fever, which is a sign of an infection or inflammation in the body. A fever is defined as a body temperature above 100.4°F (38°C).
  • Hypothermia: A low body temperature, known as hypothermia, can occur in cold environments or due to certain medical conditions. A body temperature below 95°F (35°C) is considered hypothermia.
  • Hyperthyroidism: An overactive thyroid gland can cause the body to produce too much heat, leading to a high body temperature.
  • Medications: Certain medications, such as antipsychotics and antidepressants, can affect body temperature regulation.
  • Trauma: Serious injury or surgery can cause the body to produce too much heat as a response to the trauma.

Symptoms of abnormal body temperature:

  • Fever: Symptoms of a fever can include sweating, chills, headache, muscle aches, and fatigue.
  • Hypothermia: Symptoms of hypothermia include shivering, numbness, confusion, and slow breathing.
  • Hyperthyroidism: Symptoms of hyperthyroidism include weight loss, rapid heartbeat, and sweating.

Prevention of abnormal body temperature:

  • Fever: The best way to prevent a fever is to practice good hygiene, such as washing your hands frequently, and avoiding close contact with people who are sick.
  • Hypothermia: To prevent hypothermia, it is important to dress warmly in cold weather, and avoid staying out in the cold for prolonged periods of time.
  • Hyperthyroidism: To prevent hyperthyroidism, it is important to manage any underlying medical conditions that can cause an overactive thyroid gland.
  • Medications: If you are taking medications that can affect body temperature regulation, it is important to follow your doctor's instructions and monitor your body temperature regularly.
  • Trauma: To prevent abnormal body temperature due to trauma, it is important to take steps to prevent injuries and accidents.

In conclusion, abnormal body temperature can be caused by fever, hypothermia, hyperthyroidism, medications, and trauma. It is important to be aware of the symptoms and take the necessary steps to prevent abnormal body temperature. If you have a fever or other symptoms of abnormal body temperature, it is important to seek medical attention.

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.
