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:
Cause | Probability | Status |
---|---|---|
Chronic Renal Insufficiency | 91% | Confirm |
Aspartame/Neotame Side-Effects | 17% | Unlikely |
Non-Hodgkin's Lymphoma | 13% | Unlikely |
Psoriasis | 2% | Ruled out |
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→ Moderately → Severely |
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.
