3 areas of the body where itching can be a sign to pay attention to.

Occasional mild discomfort in these areas may be normal. But it’s a red flag when the itching is:

Deep and intense
Persistent
Worse at night
No visible skin lesions

In these cases, it can be related to liver problems, especially when there is an alteration in the flow of bile.

The liver produces bile to help digest fats. When that flow is impaired, certain substances can build up in the blood and irritate nerve endings from inside the body. That is why the person feels intense itching, even if the skin looks normal.
Signs that accompany this itching:

Excessive tiredness
