Itching is called pruritus.
Understanding Pruritus
Pruritus is the medical term for the sensation we commonly know as itching. It's a common condition that creates a desire to scratch the affected skin. Here's a more detailed look:
- Definition: Pruritus is defined as the sensation that causes a desire to scratch.
- Mechanism: It is believed to result from the stimulation of specific nerve endings in the skin.
- Symptom, Not a Disease: Importantly, pruritus is a symptom and not a disease itself. This means it's often a sign of an underlying health issue.

Understanding pruritus includes knowing how it manifests and its various causes:
Manifestation:
- Unpleasant Sensation: Pruritus can manifest as an unpleasant sensation that can range from mild to severe.

- Potential for Skin Damage: Excessive scratching may lead to skin damage, infections, or the development of lesions.
Common Causes:
- Skin Conditions: Many skin conditions can cause pruritus, such as eczema, psoriasis, and dry skin.
- Allergies: Allergic reactions to substances like pollen, foods, or medications may result in itching.
- Systemic Illnesses: Certain diseases that affect the whole body, such as kidney disease or liver disease, can cause itching.
