Scabies, lice, or fungal infections can cause generalized itching.

Viral infections, such as chickenpox or shingles, may produce widespread irritation.

Medications

Certain antibiotics, blood pressure medications, or chemotherapy drugs may trigger body-wide itching as a side effect.

Other Factors

Stress, dry skin, or hormonal changes can exacerbate itching.

Diagnosis: More Than Just a Scratch

A proper diagnosis often requires:

A detailed medical history and symptom review

Physical examination of the skin

Blood tests to check liver, kidney, and thyroid function

Allergy testing if a reaction is suspected

Skin biopsy in rare cases

Treatment Options

Treatment depends on the underlying cause:

Topical treatments: Moisturizers, anti-itch creams, or medicated lotions

Oral medications: Antihistamines, corticosteroids, or medications targeting liver/kidney issues

Lifestyle adjustments: Avoiding triggers, taking lukewarm showers, and using gentle soaps

Medical intervention: Addressing underlying conditions like liver disease, kidney disease, or thyroid imbalance
