5 common causes of itchy skin
Discomforts that develop on the surface of the skin can be frustrating to deal with, especially when these are caused by conditions that may be chronic in nature. Something as basic as itchy skin can seriously affect one’s routine if the symptom is left unchecked. Many underlying triggers of a skin itch might develop as mild symptoms but can eventually progress into something more severe. Here are 5 common causes of itchy skin: Skin diseases and disorders One of the most common causes of itchy skin is linked to several known and common skin disorders like eczema (atopic dermatitis), psoriasis, and even dry skin or xerosis. Apart from this, skin irritation can also be caused by scabies, burns, scars, hives, and insect bites, which can lead to mild to moderate itching. Allergic reactions Apart from internal triggers of itching skin, several types of materials and exposure to environmental pollutants can also cause skin rashes that cause itching to develop suddenly. For example, soaps contain compounds that can trigger a dermatitis reaction when the lather comes in contact with the skin. The same goes for lotions, perfumes, deodorants, antiperspirants, and fragrances used for the skin. Even many common types of fabrics, like wool or synthetic blends, can trigger a topical allergic reaction. Even insect bites can cause a chemical reaction that results in itching. Internal organ problems Kidney problems, blood disease, diabetes, liver diseases, an overactive thyroid gland, and other autoimmune responses that trigger changes in the metabolism can also cause itchy skin. These reactions could be a side effect of a prescription to manage internal complications or may develop due to an immune system response that attacks healthy skin. Nerve problems Certain progressive chronic disorders can trigger disruption in vital nerve communications, resulting in confused signals that cause these symptoms of itchy skin and rashes to develop on the surface. Existing conditions like shingles, HIV, nerve damage due to trauma or injury, tumors in the brain, stroke, and even incurable diseases like multiple sclerosis can trigger nerve damage that results in these itchy symptoms to develop without warning. Psychological triggers Itchy skin can also develop as a result of psychological trauma like depression, anxiety, obsessive compulsive disorders, or even psychosis. The eerie sensation of tingling or crawling under the skin could result from the mind playing tricks.
