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.
Itching can be caused by:
- Xerosis. This is the most common cause, frequently seen in winters. Associated with older age, frequent bathing in hot showers or baths, and high temperature and low humidity environments.
- Skin conditions (such as psoriasis, eczema, sunburn, athlete's foot and many others). Most are of an inflammatory nature.
- Insect bites, such as those from mosquitos or chiggers.
- Allergic reactions to contact with specific chemicals, such as Urushiol from Poison Ivy or Poison Oak.
- Hodgkin's disease
- Jaundice (bilirubin is a skin irritant at high concentrations)
- Polycythemia, which can cause generalized itching due to increased histamine
- Scabies or infection with lice or worms
- Thyroid illness
- Diabetes Mellitus
- Dandruff (an unusually large amount of flaking is associated with this sensation)
- Drug Side Effect- acetaminophen, caspofungin acetate, Hydrocodone bitartrate and acetaminophen, Ketorolac tromethamine, Naproxen sodium, Piroxicam, Tacrolimus
- Iron deficiency anemia
- Parasitic infections
- Psychiatric
- Medication:
- Allergy - (due to reaction of an individual's immune system to certain chemical compounds)
- Photodermatitis – (sun)light reacts with chemicals in the skin, leading to the formation of irritant metabolites
- Directly (e.g. morphine)
- Other drugs- Ofloxacin, Tretinoin
- Lovaza
- Triazolam
- Tazarotene
- Travoprost
- Cholestasis
- Related to pregnancy:
- Drug side effects: Acetaminophen, Acetylcysteine, Conjugated estrogens, Spironolactone, Hydrochlorothiazide, Tolbutamide
