What Causes Itchy Skin?
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:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "itchy skin" as a symptom. Here are eight possibilities (more below
- Non-Hodgkin's Lymphoma
- Cirrhosis Of The Liver
- Liver Function Testing Need
- Kidney Disease
- Chronic Renal Insufficiency
- Aspartame/Neotame Side-Effects
- Electrical Hypersensitivity
- Liver Congestion
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
high systolic blood pressure
severe right lumbar pain
shortness of breath when at rest
frequent nighttime urination
reasonably controlled diabetes
short-term low-carb dieting
breast soreness during cycle
regular runny nose
edema of the abdomen
very pale fingernails
macrocytic red cells
... and more than 110 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of itchy skin:
|Chronic Renal Insufficiency
|Liver Function Testing Need
|Cirrhosis Of The Liver
* This is a simple example to illustrate the process
Arriving at a Correct Diagnosis
is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.
In the Skin-Related Symptoms
section of the questionnaire, The Analyst™
will ask the following question about itchy skin:
Does your skin tend to itch often, perhaps worse at night?
→ No / don't know
Based on your response to this question, which may indicate itchy skin, The Analyst™
will consider possibilities such as:
Cirrhosis of the Liver
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.
Liver Function Test Requirement
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.
