Itchy skin (pruritus)

What causes itchy skin?

There are many reasons for itchy skin, ranging from simple dryness to skin allergies and medical conditions. Common causes include:

• Dry and itchy skin due to weather changes, dehydration, or harsh soaps
• Itchy skin allergy triggered by detergents, jewelry, cosmetics, fabrics, or insect bites
• Eczema, psoriasis, hives, or fungal infections
• Contact dermatitis (skin reacting to irritants or allergens)
• Sunburn or heat rashes
• Certain medications
• Systemic health issues like thyroid disorders, liver/kidney problems, or diabetes (less common but essential)

Understanding what’s behind the itch helps you know when to seek medical help and guides effective treatment for long-term relief.

Symptoms that often appear with itchy skin

Itchy skin can affect any part of the body and may appear with:

• Redness or rashes
• Small bumps or itchy patches on the skin
• Flaking or cracked skin
• Swelling or warmth in the affected area
• Thickened skin from frequent scratching

Scratching may bring temporary relief, but it can damage the skin and increase the risk of infection.

When should you see a doctor? Seek medical advice if symptoms persist beyond 2-3 weeks or if you notice signs like pus, fever, or spreading rash, to ensure proper care.Seek medical advice if:

• The itching lasts more than 2–3 weeks
• The itch is severe, interrupts sleep, or spreads quickly
• Generic creams do not help
• There is pus, fever, or signs of infection
• You notice yellowing skin, sudden weight loss, or fatigue, along with itching

Early evaluation can help identify the cause and prevent complications.
