Hepatotoxicity[edit]
Hepatotoxicity is a medical term that denotes damage or injury to the liver caused by exposure to toxins. These toxins can originate from various sources such as medications, chemicals, herbal compounds, or dietary supplements. It's also interchangeably termed as drug induced liver injury.
Introduction[edit]
The liver is a vital organ responsible for metabolizing substances, producing bile for digestion, and detoxifying the body of harmful agents. When hepatotoxic substances enter the system, they can interfere with these critical functions, leading to potential health consequences.

Causes of Hepatotoxicity[edit]
Hepatotoxicity can be triggered by various agents:
- Medications: Many drugs, even those prescribed for common conditions, can result in liver injury if taken in large doses or for extended periods.
- Chemicals: Industrial chemicals or household agents can cause hepatotoxicity if ingested or absorbed.
- Herbal compounds: Some herbs, believed to be safe and natural, can have toxic effects on the liver when consumed in high quantities or over prolonged periods.
- Dietary supplements and food toxins: Certain supplements, especially when consumed in excess, can lead to liver damage.

Diagnosis and Symptoms[edit]
Symptoms of hepatotoxicity might not be evident immediately after exposure to a hepatotoxic agent. However, when they do manifest, they might include jaundice (yellowing of the skin and eyes), dark urine, fatigue, abdominal pain, nausea, vomiting, and anorexia. Blood tests often reveal elevated liver enzymes, which serve as indicators of liver injury.
Prevention and Treatment[edit]
Preventing hepatotoxicity involves being informed about the potential hepatotoxic effects of substances and taking them in moderation or under medical supervision. It's essential to consult healthcare professionals when starting any new medication, supplement, or herbal product. Treatment depends on the severity of the liver injury and the causative agent. In some cases, discontinuation of the hepatotoxic agent might suffice, while in more severe instances, hospitalization and specific medical interventions might be necessary.
