Itching can be a vexing and persistent issue with a myriad of potential triggers. One such cause is the natural aging process, where “The skin barrier doesn’t work as well as it used to and things that may not have irritated you before may now be absorbed in the skin and cause itching,” explains Dr. Arndt. Moreover, the skin undergoes changes including “a somewhat impaired immune response, a reduction in fat and blood flow, and altered …” In a groundbreaking discovery reported on April 2 in Gastroenterology, researchers found that severe liver disease can result in intense itching, which is attributed to more than just the organ’s dysfunction; it suggests that the skin’s outer layer is far more complex than just an insulating barrier.
The sensation of itch is an intricate bodily response, potentially arising from allergies, insect bites, illnesses, medications, and dry skin. Hormonal shifts due to menopause and pregnancy may also lead to skin dryness and exacerbate itching, particularly at night. Medications such as antibiotics, blood pressure pills, opioids, and diuretics, along with skin care products like soaps, deodorants, or bug repellents, are also common culprits. In some cases, nighttime itching could be an indication of a more serious condition.
Unexplained itching might be the result of unrecognized immune system abnormalities. A study conducted by the Center for the Study of Itch at Washington University School of Medicine in St. Louis unveiled immune system irregularities in patients with chronic itching.
Drug rashes are another itch-inducing factor. They can manifest as hives that move around the skin, often tied to histamine release, with antihistamines serving as a common remedy. However, some drug rashes are delayed, appearing several days after medication commencement, with pink and red bumps emerging on the chest and back, as detailed by Harvard Health.
Dry skin, especially prevalent in winter, can be particularly irritating. To mitigate this, one should refrain from scratching, wear protective clothing outdoors, use a humidifier, and limit showers to five minutes with lukewarm water. Hot water and scented soaps can further strip the skin of its natural oils. Moisturizing frequently with an oil-based ointment is also advisable.
Anaphylaxis is an extreme allergic reaction that can involve intense itching, amongst other severe symptoms. It’s a systemic response that includes warmth, flushing, hives, and swelling, requiring immediate medical attention as outlined by Harvard Health.
To combat dry, itchy skin, Harvard Health recommends patting the skin dry rather than rubbing after a shower and applying moisturizer while the skin is still damp. This helps to lock in moisture and protect the skin.
