Is Itching a Serious Problem?
Itching, or pruritus, is usually not serious. However, it can sometimes indicate an underlying medical condition. The severity and cause of the itching determine whether it's a serious problem.
Itching can be a symptom of various serious conditions, including:
- Underlying diseases: Itching can be a sign of liver or kidney disease, thyroid problems, or nervous system dysfunction. Treating the underlying disease is key to resolving the itching. (Source: WebMD)
- Severe itching: Intense itching that doesn't subside after a few weeks or has no apparent cause warrants medical attention. (Source: MedlinePlus)
- Itching related to cancer treatments: Itching caused by chemotherapy or immunotherapy may require medical intervention. (Source: Canadian Cancer Society)
