Overview
There are many causes of itching. Examples include skin diseases, systemic diseases, allergies, medications, insect stings among many others
Causes
The feeling of itchiness can be caused by a movement of hair or the release of a chemical (histamine) from cells under the skin. Itchiness is regarded as protective, as it helps creatures remove parasites that land on their skin.
Causes of itching listed in alphabetical order:
- Allergic reactions due to contact with specific chemicals, such as Urushiol from Poison Ivy or Poison Oak.
- Cholestasis [1]
- Skin conditions (such as psoriasis, eczema, sunburn, athlete's foot, Dandruff and many others). Most are of an inflammatory nature.
- Diabetes Mellitus[2] [3]

- Insect bites, such as those from mosquitos, ants, and ticks.
- Jaundice as (bilirubin is a skin irritant at high concentrations)
- Parasitic infections
- Photodermatitis – sunlight reacts with chemicals in the skin, leading to the formation of irritant metabolites
- Polycythemia, which can cause generalized itching due to increased histamine as a result of higher numbers of mast cells
- Psychiatric
- Related to pregnancy:
- Scabies or infection with lice or worms
- Thyroid illness
- Uremia [7]
