Itchy skin can have various causes, ranging in severity from 'troubling' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose itchy skin, we could:
|Liver Function Testing Need||97%||Confirm|
|Chronic Renal Insufficiency||5%||Ruled out|
|Non-Hodgkin's Lymphoma||3%||Ruled out|
|Cirrhosis Of The Liver||1%||Ruled out|
|Electrical Hypersensitivity||0%||Ruled out|
Does your skin tend to itch often, perhaps worse at night?
Possible responses:→ No / don't know
Some people with liver or biliary cirrhosis experience intense itching due to bile products that are deposited in the skin.
The reason why patients with liver disease itch is not known, although it is commonly believed that some substances accumulate in the blood as a result of a poorly functioning liver and thus cause itching. A simple blood test can exclude liver disease as a cause for the itching, as liver enzymes are often elevated with liver involvement.
