The most common causes of itchy skin

Whether it is located in a certain area of ​​the body or generalized, whether or not accompanied by rash, the itching (pruritus) is a disturbing problem for anyone who is experiencing it. There are a number of causes that are frequently the root of this disease, their correct identification being essential to treating the problem.

Skin rashes can occur without visible changes in the skin or may be associated with: redness, spots or blisters, dry skin, cracked, thickened or even bleeding areas. In many situations, home care measures, such as daily hydration, gentle cleansing, and bathing with lukewarm water can help alleviate the problem at least for the moment. Its long-term treatment requires identification and removal of the underlying cause:

Dry skin

This is one of the most common causes of skin itching, being a consequence of environmental factors such as excessive warm or cold weather or low humidity. Excessive washing and cleaning products that are too aggressive with the skin can also cause it to dry. “If there are triggering factors, this problem can affect any age group. At the same time, as people grow older, it is natural for the skin to become thinner and drier, which may favor the onset of itching ,  explains the dermatologist.

Certain diseases

Many skin problems such as xerosis, dermatitis, psoriasis, burns, scars, insect bites and urticaria may also cause skin itching.

On the other hand, long-lasting skin itching may in some cases be a symptom of more serious illnesses, including: blood disease, diabetes, kidney or liver disease, HIV, or signs of overactive thyroid.

“Itchy skin is commonly found in people who have a disease that affects their blood and can also be a symptom of advanced kidney disease. In these people, the itching will be widespread and, especially, intense on the back, arms and legs. Itching of the skin is also common in people who have liver disease such as hepatitis C, cirrhosis or biliary duct obstruction. When itching is a sign of liver disease, it often starts on the palms and soles and then extends to other parts of the body”.

Certain medicines

If the itching occurred with the onset of a new treatment, then it could be the cause.

“Certain drugs, such as statins (used for cholesterol), blood pressure lowering drugs and opioids, are all known to cause itching that is not necessarily accompanied by skin lesions. In some cases, the itching will stop spontaneously when the medication ceases. It is advisable to consult a prescribing physician who may recommend switching to another medication ,  explains the dermatologist.

Irritation and allergic reactions

The skin may develop an allergic reaction to certain substances, of which nickel is commonly found in many products every day, from mobile phones, jewelery, spectacle frames, zippers and buckles. Other substances that may cause allergic skin reactions include: nail polish, perfumes, shampoos, latex, etc.

If the itching does not disappear following home treatment, if it is severe, relapsed or is associated with other symptoms – such as redness and swelling of the skin or jaundice (yellowing of the skin and whites of the eyes), a visit to the dermatologist is recommended to diagnose with the exact nature of the condition, recommending a proper treatment scheme for each case.
