Chronic Urticaria (Hives): Causes, Triggers and Integrative Care
Medically reviewed by Dr Krushal Pabari, MD, PGCP - Rheumatic & Musculoskeletal Diseases · Last reviewed: 4 November 2026
Key facts
Chronic urticaria means itchy hives (wheals), sometimes with swelling, that keep coming back for more than six weeks. In most people no single outside cause is found, and the immune system is often involved [1][2]. People with chronic urticaria tend to have lower vitamin D, and in trials vitamin D supplements reduced symptom scores [3]. We look for triggers and support the immune system with functional medicine, functional nutrition and stress care, and vitamin D where tests show it is low, alongside your antihistamines, in coordination with your existing consulting physician.

In our Resources section, our clinical team discusses chronic urticaria (hives) and its management in detail: a low-histamine diet, gut health and functional nutrition.
What is chronic urticaria? Spontaneous and inducible hives
Hives happen when mast cells in the skin release histamine and other chemicals, causing raised, itchy welts that come and go within hours, sometimes with deeper swelling of the lips, eyelids or hands (angioedema) [1]. About 1 in 5 people have hives at some point [1]; chronic urticaria is less common, affecting about 1.4% of people in Asia and 0.5% in Europe [4].
- Acute urticaria (up to 6 weeks) often follows an infection, a food, a medicine or a physical trigger.
- Chronic spontaneous urticaria comes without a clear outside trigger.
- Chronic inducible urticaria is set off by physical triggers such as pressure, cold, heat or exercise.
Common symptoms: intense itching, often worse at night; red, raised welts that move around the body; swelling around the eyes, lips or hands.
Seek emergency care if swelling affects your tongue or throat or you have difficulty breathing.
Chronic hives causes and triggers: autoimmunity, thyroid, infections, stress and food
- Autoimmunity: in many people with chronic spontaneous urticaria, the immune system makes antibodies that activate mast cells, and other autoimmune conditions are more common [2].
- Thyroid: thyroid antibodies are raised in at least 1 in 10 people with chronic spontaneous urticaria, and hypothyroidism and Hashimoto’s thyroiditis are more common [5].
- Infections, stress, medicines (such as painkillers like ibuprofen) and, in some people, food additives can worsen hives. True food allergy is rarely the cause of chronic hives [1].
- Nutrient levels: low vitamin D is common [3]; we also check B12 and iron.
Vitamin D and chronic urticaria: what the research shows
- People with urticaria have vitamin D levels about 9 ng/mL lower on average than people without it, especially adults with chronic urticaria [3].
- In 6 supplementation trials, vitamin D reduced urticaria symptom scores [3].
- A separate review found that higher doses for 4 to 12 weeks may reduce disease activity in some people with chronic spontaneous urticaria, and called for larger trials [6].
Working in coordination with your existing consulting physician
The 2026 international urticaria guideline recommends daily non-drowsy antihistamines first, a higher antihistamine dose if needed (under medical advice), then add-on omalizumab, dupilumab or remibrutinib, and then ciclosporin for hives that do not settle [1]. Short courses of steroids are used only for bad flares. We support this care: finding triggers, correcting nutrients and supporting gut and thyroid health. Antihistamines and other medicines are adjusted under clinical guidance from Team Cure4Pain, in coordination with your existing consulting physician.
Our integrative approach
- Orthomolecular medicine: vitamin D (Coimbra Protocols, when indicated), magnesium and zinc, vitamin C and quercetin, B vitamins and selenium.
- Functional medicine: looking for triggers and contributors (gut health, food sensitivities, infections), gut support (probiotics, supervised elimination, digestive enzymes) and thyroid support.
- Lifestyle support: anti-inflammatory nutrition (fewer processed foods, preservatives and alcohol) and stress reduction with breathwork and mindfulness.
One of the therapies we use is the Coimbra Protocol (supervised vitamin D therapy): read how it works, who it may suit and how it is monitored.
Monitoring and safety
Baseline tests: vitamin D, IgE, thyroid profile with thyroid antibodies, blood count, CRP and ESR; further tests when needed. Any change to antihistamines or steroids is made under clinical guidance.
What to expect
Chronic urticaria often settles over time, but how long it takes varies a lot [1]. Some people notice less itching within weeks; for others it takes months. We review symptoms (a simple hives diary helps) and tests at each follow-up. Individual results vary.
De-identified patient cases
- Female, 29, chronic urticaria for 3 years: after 4 months of monitored vitamin D and gut support, she reported fewer outbreaks and better sleep, and used antihistamines less often.
- Male, 35, urticaria with Hashimoto’s thyroiditis: after 7 months of integrative support, he reported fewer outbreaks, and his thyroid tests were stable; any change to steroids was made by his doctor.
Individual results vary. Not typical.
Related: fibromyalgia and other autoimmune conditions
Chronic urticaria often comes with other conditions. More than a third of people with chronic urticaria also have fibromyalgia [7], and thyroid autoimmunity is common [5]. See: Fibromyalgia · Hashimoto’s Thyroiditis · Psoriasis · Lupus.
Chronic urticaria FAQs
Is chronic urticaria an autoimmune disease?
Often, yes. In many people with chronic spontaneous urticaria the immune system makes antibodies that activate mast cells, and other autoimmune conditions, especially of the thyroid, are more common [2][5]. Antihistamines remain the first treatment [1].
Can vitamin D help with hives?
Studies suggest it can: people with chronic hives tend to have lower vitamin D, and supplements reduced symptom scores in trials [3]. We use lab-guided dosing for safety.
Will I always need antihistamines?
Not necessarily. Chronic urticaria often settles with time [1], and many people need less medicine as triggers and underlying factors are addressed. Antihistamines are adjusted under clinical guidance; please do not stop them on your own.
Why do my hives get worse at night?
Night-time itching is common, linked to the body’s daily rhythm of histamine and stress hormones. Good sleep habits and anti-inflammatory nutrition can help.
Can stress cause chronic hives?
Stress can trigger or worsen hives by increasing mast cell activity. Breathwork and lifestyle support are part of our plan.
Is urticaria linked to thyroid problems?
Yes. Thyroid antibodies and hypothyroidism are more common in chronic urticaria [5], so thyroid testing is part of our evaluation.
Can food triggers cause recurring hives?
True food allergy rarely causes chronic hives [1], but some people react to additives or particular foods. A short, supervised elimination can show whether food plays a part.
How long does it take to see improvement in chronic hives?
It varies. Some people notice less itching within weeks; for others it takes months. We review progress at each follow-up.
How much does treatment for chronic hives cost?
The consultation fee is shown when you book. Blood tests can be done at a laboratory near you. Supplements can be bought from a source of your choice, as long as the quality and dose are approved during your consultation; typical monthly costs are discussed in your first consultation.
