Persistent Itching Is Worth Looking Into

An itchy patch of skin is usually easy to explain. Perhaps you’ve been bitten by an insect, used a new soap, or simply have dry skin. But if you’re repeatedly scratching without being able to see an obvious rash, it’s worth paying attention to the pattern.

Dry skin is a common culprit, particularly as skin becomes thinner and produces less natural oil with age. Hot showers, harsh soaps, and dry indoor air can make the problem worse. Using a gentle moisturiser regularly, particularly after bathing, can help protect the skin’s moisture barrier.

But persistent itching can have other causes. Some medicines can cause itching, and skin conditions such as eczema can sometimes be subtle rather than producing a dramatic rash. Less commonly, ongoing itching can be associated with problems affecting the liver, kidneys, thyroid, or blood.

Think about when the itching started and whether anything changed around the same time. Did you begin taking a new medicine? Change your soap or laundry detergent? Spend more time in heated or air-conditioned rooms? Noticing these details can help your healthcare professional work out where to start.

Try not to scratch repeatedly, even though that can be difficult. Scratching can damage the skin and create small breaks that become irritated or infected. Keeping your nails short and using a cool, damp cloth on an itchy area may provide some temporary relief.

It is also worth looking at the rest of your skin. If you notice dryness, scaling, redness, swelling, or a new rash, make a note of where it appears and whether it changes over time. A photograph can be useful if the problem comes and goes before your appointment.

See your doctor if itching is persistent, severe, affecting your sleep or happening across much of your body without an obvious explanation. Seek prompt medical advice if it occurs alongside symptoms such as unexplained weight loss, fever, night sweats, or yellowing of the skin or eyes.

Itching is rarely something people put on their list of health concerns. But if you’re scratching night after night and cannot work out why, don’t automatically blame it on getting older. Your skin may be telling you that something needs a closer look.
