What is Pruritus?
Pruritus is also known as itching and may be defined as a tingling sensation of the skin that causes a strong desire to scratch the area to obtain relief. Itching can either be confined to a certain part of the body (localized) or develop all over the body (generalized).
It may due to skin diseases, internal disorders, external factors or as a result of the faulty processing of the itch sensation within the nervous system. This irritation of the skin can cause immense discomfort and distress, sometimes even leading to anxiety, depression and loss of sleep.
What Causes Pruritus?
Pruritus may be the caused by several things. Common causes include fungal infections such as jock itch, athlete’s foot, thrush and candidiasis. Chicken pox, hives, pruritus ani, and parasitic infestations such as lice and scabies are also very itchy. Internal conditions such as kidney failure, liver and thyroid disease hyperthyroidism and hypothyroidism, blood disorders or iron deficiency anemia can cause itchiness.
Neurologic conditions such as pinched nerves and infectious diseases like HIV can result in severe itching. Skin diseases or conditions such as dry skin, eczema, psoriasis, and sunburn also cause the skin to itch and become distressed. It may even be due to hormonal factors – often occurring during pregnancy and menopause. Pruritus that occurs as a result of exposure to certain external factors includes allergic reactions, irritation from chemicals or plants, insect bites and some medications. Psychological factors such as stress or anxiety can also exacerbate itching.
The diagnosis of pruritus is based on the symptoms presented as well as a physical examination. Certain tests may be ordered and include:
- Blood tests
- Skin scraping
Help for Pruritus
Treatment generally depends on the cause and severity of the itch. Various topical medications such as calamine lotion, menthol or camphor lotion or mild corticosteroids may be used for symptomatic relief. Oral antihistamines or ultraviolet light therapy may also be prescribed to treat the itch. Cool the skin with damp dressings or a lukewarm shower to relieve itch and use emollients regularly to keep the skin hydrated.
Natural and holistic therapies using herbs and homeopathic remedies are highly effective for treating the common causes of itching. Not only are these remedies safe and gentle on the body, but also benefit your overall health.
A combination of herbal and homeopathic ingredients such as Galium aperine (Cleavers), Trifolium pratense (red clover), Natrium muriaticum and Kalium sulphate are used to support skin health and functioning as well as cleanse and purify the body’s system. In addition, Calendula officinalis (Marigold), Melaleuca laterifolia (Tea Tree Oil) and Lavendula officinalis (Lavender) contain supportive properties that help to calm and soothe angry skin.
