Jaundice
Jaundice is a medical condition characterized by the yellowing of the skin, mucous membranes, and the whites of the eyes. This yellow discoloration is caused by an excess of bilirubin, a yellow pigment produced during the breakdown of red blood cells. Bilirubin is normally processed by the liver and excreted in the bile, but when there is an issue with the liver's function or the bile ducts, it can lead to the accumulation of bilirubin in the body.
The most common symptom of jaundice is the noticeable yellowing of the skin and eyes. Other symptoms may include dark urine, pale stools, fatigue, abdominal pain, and itching. Jaundice itself is not a disease but rather a sign of an underlying issue affecting the liver or the bile ducts.
There are several potential causes of jaundice, and they can be broadly categorized into three types: pre-hepatic, hepatic, and post-hepatic.

Pre-hepatic jaundice
This type occurs when the excessive breakdown of red blood cells leads to an increased production of bilirubin. Conditions such as hemolytic anemia, where red blood cells are destroyed more rapidly than usual, can result in pre-hepatic jaundice.
Hepatic jaundice:
This type is related to disorders directly affecting the liver. Liver diseases such as hepatitis, cirrhosis, and alcoholic liver disease can impair the organ's ability to process and excrete bilirubin, leading to its accumulation in the body.
Post-hepatic jaundice
Also known as obstructive jaundice, this type occurs when there is a blockage in the bile ducts that prevents the normal flow of bile. Common causes include gallstones, tumors, or inflammation of the bile ducts.
Diagnosis of jaundice involves a thorough medical history, physical examination, and various blood tests to determine the levels of bilirubin and liver enzymes. Imaging studies such as ultrasound, CT scans, or MRI may be employed to identify any structural abnormalities in the liver or bile ducts.
Treatment for jaundice depends on the underlying cause. In some cases, addressing the root condition may resolve jaundice, while in others, supportive measures such as medication, lifestyle changes, or even surgery may be necessary. It is crucial for individuals experiencing symptoms of jaundice to seek prompt medical attention to identify and address the underlying cause.
Jaundice is a visible manifestation of an underlying issue affecting the liver or bile ducts. While it can be a symptom of various medical conditions, timely diagnosis and appropriate treatment are essential to manage and resolve jaundice effectively.
Bilirubin Metabolism:
Bilirubin is a natural byproduct of the breakdown of hemoglobin in red blood cells. When red blood cells complete their life cycle, they are broken down in the spleen, releasing hemoglobin. This hemoglobin is then converted into biliverdin, which is further processed into bilirubin. The liver plays a crucial role in processing bilirubin and excreting it into the bile, which is then eliminated from the body through stool.
