Itching in 9 Areas: A Warning Sign of Malignant Tumors, Number 7 Is the Most Common

Less common medical causes

In some situations, itching may be linked to internal health conditions, such as:

• Liver disorders (can cause generalized itching without rash)
• Kidney disease (due to toxin buildup)
• Thyroid imbalance
• Iron deficiency anemia
• Certain blood disorders (rare cases)

Importantly, these conditions usually come with other noticeable symptoms, not itching alone.
