Learning objectives
- Explain digestion, energy storage, and toxin removal.
- Explain multiple causes of liver disease.
Digestion, energy storage, and toxin removal
The liver is the largest organ inside the body and helps digest food, store energy, and remove toxins. These broad roles explain effects beyond a single digestive complaint. Processing substances, keeping energy available, and handling harmful exposures are different tasks performed by the same organ. A liver problem can therefore have consequences in several areas of health, and the precise cause affects what further information is needed.
Multiple causes of liver disease
Viruses including hepatitis A, B, and C can cause liver disease. Other causes involve medicines, poisons, toxins, or excessive alcohol. Cancer and inherited conditions such as hemochromatosis or Wilson disease are additional categories. Liver disease is not a synonym for alcohol injury. Different causes require different investigation, so assuming every affected person has the same exposure history or inherited risk can obscure the actual problem.
