Itching can be annoying and uncomfortable, but usually it’s nothing to worry about. However, if you have unexplained itching, it could be a sign of a serious health issue.

In this article, we’ll explore the possible causes of unexplained itching and what you should do if you experience it.

What is unexplained itching?

Unexplained itching is itching that doesn’t have an obvious cause. It can be generalized (i.e., all over the body) or localized (i.e., in one specific area). Itching can be acute (lasting less than 6 weeks) or chronic (lasting longer than 6 weeks).

Unexplained itching can be a symptom of an underlying health issue, and it’s important to get it checked out by a healthcare provider. Here are some possible causes of unexplained itching:.

1. Liver disease

Liver disease can cause generalized itching because when the liver isn’t functioning properly, it can’t effectively rid the body of toxins. These toxins build up in the blood and can cause itching.

Liver disease can also cause jaundice (yellowing of the skin and eyes) and abdominal pain.

2. Kidney disease

Just like with liver disease, kidney disease can cause generalized itching due to a buildup of toxins in the blood. Kidney disease can also cause fluid retention, high blood pressure, and decreased appetite.

3. Thyroid problems

Thyroid problems can cause both generalized and localized itching. When the thyroid gland is underactive (hypothyroidism), the skin can become dry and itchy.

On the other hand, when the thyroid gland is overactive (hyperthyroidism), localized itching can occur.

4. Diabetes

Diabetes can cause generalized itching as a result of high blood sugar levels. When blood sugar levels are high, the body loses fluids, which can cause the skin to become dry and itchy.

Diabetes can also cause nerve damage, which can lead to localized itching.

5. Cancer

Although rare, cancer can cause itching. Itchy skin can be a symptom of lymphoma (cancer of the lymphatic system) or leukemia (cancer of the blood and bone marrow).

6. Allergies

Allergies can cause both generalized and localized itching. When the body is exposed to an allergen (e.g., pollen, pet dander), it can trigger an allergic reaction, which can cause itching, hives, and other symptoms.

7. Medications

Some medications can cause itching as a side effect. Itching can be a side effect of certain antibiotics, antifungal medications, and pain medications.

If you’re experiencing itching after starting a new medication, talk to your healthcare provider.

8. Skin conditions

There are a number of skin conditions that can cause itching. Eczema, psoriasis, and dermatitis are three common skin conditions that can cause itching. All of these conditions cause inflammation of the skin, which can lead to itching.

9. Parasites

Parasites, such as scabies and lice, can cause localized itching. Scabies is caused by a tiny mite that burrows into the skin, while lice are tiny insects that live on the scalp and hair. Both can cause intense itching.

10. Stress

Stress can cause generalized itching as a result of the body’s natural stress response. When the body is stressed, it releases histamine, a chemical that can cause itching and other symptoms.

What should you do if you have unexplained itching?

If you have unexplained itching, it’s important to see a healthcare provider. Your healthcare provider will want to rule out any underlying health issues that could be causing the itching.

They may also recommend treatment options to relieve the itching.

If you have an underlying health issue that’s causing the itching, treating that issue should help relieve the itching. For example, if you have liver disease, treating the liver disease should help relieve the itching.

If you have an allergy, avoiding the allergen should help relieve the itching.

If no underlying health issue is found, your healthcare provider may recommend over-the-counter anti-itch creams, such as hydrocortisone cream.

They may also recommend lifestyle modifications, such as taking lukewarm baths and avoiding hot showers, to help relieve the itching.

Conclusion

While itching can be annoying, it’s usually not a cause for concern. However, if you have unexplained itching, it could be a sign of a serious health issue.

Liver disease, kidney disease, thyroid problems, diabetes, cancer, allergies, medications, skin conditions, parasites, and stress can all cause itching. If you have unexplained itching, see a healthcare provider to determine the underlying cause and get proper treatment.
