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:
|Chronic Renal Insufficiency||91%||Confirm|
|Liver Function Testing Need||2%||Ruled out|
|Electrical Hypersensitivity||0%||Ruled out|
|Cirrhosis Of The Liver||0%||Ruled out|
|Kidney Disease||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.
Excessively dry, persistently itchy skin is a possible symptom of kidney disease.
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.
