Chronic Hives That Won't Go Away: Causes & Treatment for Urticaria in Mumbai

Few conditions are as frustrating as waking up covered in itchy, raised welts with no obvious cause, only for them to vanish in hours and reappear the next day. When these itchy wheals recur on most days for more than six weeks, the diagnosis is Chronic Urticaria (chronic hives). Patients spend months blaming foods, changing diets, and switching soaps, yet the hives persist. The medical reality is that chronic urticaria (hives) is usually not an external allergy at all, it is an internal immune phenomenon, and it is highly treatable.

What Exactly Are Hives?

Hives are raised, itchy, pink or pale welts that occur when specialised immune cells in the skin (mast cells) release histamine and other chemicals. This causes tiny blood vessels to leak fluid into the skin, producing the characteristic swelling. Individual welts are migratory, they typically appear, peak, and fade within 24 hours, only for new ones to emerge elsewhere. When the deeper layers of skin swell (around the eyes, lips, hands, or feet), the condition is called angioedema, which often accompanies urticaria.

“The single biggest myth I correct in clinic is that chronic hives are caused by something the patient is eating. In the vast majority of chronic cases, no food is responsible, the immune system is essentially reacting against itself.”— Dr. Sunita Chhapola Shukla

Acute vs. Chronic Urticaria: A Critical Distinction

Understanding which type you have determines the entire treatment approach:

• Acute Urticaria: Lasts less than six weeks. It is often linked to an identifiable trigger such as a viral infection, a medication, an insect sting, or occasionally a food allergy.
• Chronic Spontaneous Urticaria (CSU): Welts appear on most days for more than six weeks with no consistent external trigger. This is the most common chronic form and is frequently autoimmune in nature.
• Chronic Inducible Urticaria: Hives are reliably triggered by a specific physical stimulus such as firm pressure or scratching (a condition called dermatographism), cold, heat, sweating, or sunlight.

Why Chronic Hives Are Rarely a Food Allergy

True IgE-mediated food allergy causes hives within minutes to two hours of eating the food, every single time it is eaten. Chronic urticaria behaves differently, it comes and goes regardless of diet, which is why elimination diets almost always fail and can lead to unnecessary nutritional restriction. Instead, chronic spontaneous urticaria is frequently associated with underlying autoimmune activity, thyroid dysfunction, chronic infections, or chronic inflammation. The goal of evaluation is not to chase foods, but to control the histamine response and identify any contributing internal factor.

The Step-Wise Medical Treatment of Chronic Urticaria

International guidelines recommend a structured, escalating treatment ladder that achieves complete control in the overwhelming majority of patients:

• Step 1: Second-Generation Antihistamines: Modern non-drowsy antihistamines are the foundation of treatment, taken daily to prevent welts rather than just react to them.
• Step 2: Up-Dosing Antihistamines: If standard doses are insufficient, guidelines support increasing the dose up to fourfold under medical supervision, which controls a large proportion of patients safely.
• Step 3: Biologic Therapy: For antihistamine-resistant cases, biological therapies such as omalizumab (an anti-IgE injectable) provide dramatic relief by targeting the immune pathway directly.
• Supportive Investigation: Targeted blood tests may be done to check for thyroid antibodies, inflammation markers, or other autoimmune contributors that need parallel management.

When to See a Specialist

If your hives have lasted more than six weeks, recur despite over-the-counter medicines, are accompanied by lip or eye swelling, or are disrupting your sleep and quality of life, a specialist evaluation is warranted. At our Dadar clinic, we confirm the type of urticaria, rule out true allergic triggers where relevant, and build a customised treatment plan that brings the condition into lasting remission.
