Itching and Liver Disease: Causes, Effects, and Relief Options.
Itching, also known as pruritus, is a common yet uncomfortable sensation that can disrupt your daily life. While it’s often linked to dry skin, bug bites, or other minor issues, persistent itching in one area or all over your body can be a symptom of something more serious — like liver disease.
In liver disease, itching can signal a more complex health concern, particularly in conditions such as primary biliary cirrhosis (PBC), primary sclerosing cholangitis (PSC), and intrahepatic cholestasis of pregnancy. Let’s dive into why liver disease can cause itching and how you can find relief.
Why Does Liver Disease Cause Itching?
The exact reason why liver disease leads to itching is not fully understood, but researchers believe several factors may contribute to this uncomfortable sensation:
-
Histamine: Elevated histamine levels are often present in people with pruritus. However, antihistamines haven’t been found to be effective in treating itching.
-
Serotonin: This neurotransmitter can affect how the body perceives itch. Interestingly, some people find relief from pruritus with selective serotonin reuptake inhibitors (SSRIs).
-
Bile Salts: When the liver isn’t functioning properly, bile salts can build up in the bloodstream and may deposit under the skin, leading to itching.
-
Female Sex Hormones: Hormonal changes from pregnancy or hormone replacement therapy may worsen itching in some individuals.
-
Serum Alkaline Phosphatase (ALP): Elevated ALP levels in the blood are common in people with liver disease-related pruritus. A simple blood test can measure ALP levels.
Managing Itching: Tips for Relief
Although itching from liver disease can be challenging to treat, there are a few ways to alleviate the discomfort. While there is no universal solution, a combination of these strategies may help you manage pruritus:
-
Use Mild, Fragrance-Free Soaps: Harsh soaps can irritate the skin, so choose gentle, fragrance-free options to minimize irritation.
-
Opt for Cool Showers: Hot water can exacerbate itching. Stick to warm or cool water when bathing or showering.
-
Apply Cold Compresses: Applying a cold, damp compress to itchy areas may provide instant relief.
-
Wear Loose, Breathable Clothing: Tight clothing can irritate the skin, so choose loose, soft fabrics that allow your skin to breathe.
-
Topical Treatments: Over-the-counter anti-itch creams with up to 1% menthol can soothe mild itching. Corticosteroids may also help.
-
Oral Medications: In more severe cases, your doctor may prescribe medications like Zoloft, Prevalite, Rifadin, or Vivitrol to reduce itching or remove bile salts from your bloodstream.
-
Use Antihistamines at Night: If itching disrupts your sleep, antihistamines can help you fall asleep despite the discomfort.
When to See a Doctor
If itching persists or worsens, especially in combination with other symptoms like yellowing of the skin or eyes, fatigue, or abdominal pain, it’s important to see a doctor for further evaluation. While itching can be a common symptom of liver disease, it may also signal an underlying condition that needs treatment.
Itching (pruritus) can be a frustrating and uncomfortable symptom, especially when it’s linked to liver disease. Although the exact cause of itching in liver diseases is still not fully understood, experts believe factors like histamine, serotonin, bile salts, and hormones may contribute to the sensation.
If you experience persistent or severe itching, speak with your healthcare provider to determine the cause and explore treatment options. With the right care, you can find relief and improve your quality of life.
