why is my skin so itchy

The itchiness of skin can be caused by a variety of reasons. Common causes include dry skin, insect bites, hives, heat rash, eczema, scabies, and psoriasis. Other causes might be allergic reactions, fungal or bacterial infections, or skin conditions like atopic dermatitis. Itchy skin can also sometimes be a sign of more serious underlying health issues such as liver disease, kidney failure, or certain cancers. Additionally, environmental factors such as dry weather or irritants like soaps and chemicals can trigger itchiness. Certain medications, dehydration, or even pregnancy may also cause skin to itch. If the itchiness is persistent, severe, widespread, or accompanied by other symptoms like rash, swelling, or pain, seeking medical advice is recommended to determine the exact cause and appropriate treatment.
