Chronic Hives (Urticaria): Causes, Symptoms and Treatment
Chronic hives, also known as urticaria, are a skin condition characterized by red, raised, and itchy welts that can come and go over a prolonged period. The exact cause of chronic hives is often challenging to pinpoint, as it can be triggered by various factors. Some common causes include allergic reactions to certain foods, medications, insect bites, infections, or environmental factors. Stress, hormonal changes, and autoimmune conditions can also play a role in triggering chronic hives.
Understanding the underlying cause of chronic hives is essential in managing the condition effectively and preventing recurrences. If you are experiencing persistent hives, it is important to consult a healthcare provider for a proper evaluation and personalized treatment plan.
What Are the Symptoms of Chronic Hives (Urticaria)
These hives may come and go, lasting for six weeks or more. Some individuals may also experience swelling, known as angioedema, in deeper layers of the skin. In some cases, chronic hives may be accompanied by fatigue or malaise. If you are experiencing persistent hives, it is important to consult a healthcare provider for proper evaluation and management.
- Chronic hives present as raised, red welts on the skin that can vary in size and shape.
- Itching is a common symptom of chronic hives and can be mild to severe, leading to discomfort.
- Swelling, known as angioedema, may occur with chronic hives, affecting the deeper layers of the skin.
- The appearance of chronic hives can be unpredictable, with outbreaks coming and going over weeks or months.
- In some cases, chronic hives may be accompanied by a burning or stinging sensation in the affected areas.

Get Second OpinionCauses of Chronic Hives (Urticaria)
Chronic hives, or urticaria, can be triggered by various factors, making it challenging to pinpoint a single cause. In some cases, the exact cause remains unknown, leading to a diagnosis of idiopathic chronic urticaria. Identifying and addressing these triggers is crucial in managing and alleviating the symptoms of chronic hives.
- Allergic reactions to food, medications, or insect bites can trigger chronic hives, leading to persistent skin inflammation and itching.
- Autoimmune disorders, such as lupus or thyroid disease, may cause the immune system to mistakenly target healthy tissues, resulting in chronic hives.
- Stress and anxiety can exacerbate chronic hives by triggering the release of chemicals that cause blood vessels to leak fluid into the skin.
- Infections like hepatitis, urinary tract infections, or viral illnesses can stimulate the body's immune response, contributing to the development of chronic hives.
- Underlying health conditions, such as hormonal imbalances or malignancies, can manifest as chronic hives, requiring thorough medical evaluation and management.
Types Of Chronic Hives (Urticaria)
Chronic hives, also known as chronic urticaria, can be categorized into different types based on their underlying causes. Other types such as cholinergic urticaria (triggered by sweating), solar urticaria (due to sunlight exposure), and contact urticaria (resulting from direct skin contact with allergens) also exist, each requiring specific management strategies.
- Chronic Idiopathic Urticaria (CIU) is the most common type of chronic hives, with no identifiable cause.
- Physical Urticaria is triggered by physical stimuli like pressure, cold, heat, or exercise.
- Aquagenic Urticaria is a rare form triggered by water contact, leading to hives within minutes.
- Dermatographic Urticaria, also known as skin writing, occurs when pressure on the skin leads to hives.
- Chronic Autoimmune Urticaria is linked to underlying autoimmune conditions like thyroid disease.
- Contact Urticaria results from direct contact with an allergen, causing localized hives.
Risk Factors
Stress, certain foods, medications, insect bites, infections, and autoimmune conditions are common risk factors. Individuals with a history of allergies or asthma may also be more prone to chronic hives. Identifying and addressing these risk factors is crucial in managing and preventing flare-ups of chronic hives.
- Stress: Psychological stress can trigger chronic hives or worsen existing symptoms by impacting the immune system.
- Allergies: Food allergies, insect bites, or environmental factors can increase the risk of developing chronic hives in susceptible individuals.
- Autoimmune disorders: Conditions like thyroid disease or lupus can be associated with chronic hives due to immune system dysfunction.
- Medications: Certain drugs, such as antibiotics or painkillers, may cause hives as a side effect, leading to chronic hives in some cases.
- Infections: Viral or bacterial infections can sometimes trigger chronic hives as the immune system responds to the infection.

Diagnosis of Chronic Hives (Urticaria)
A physical exam may help assess the extent of the hives and any associated symptoms. Blood tests can reveal potential causes such as allergies, autoimmune conditions, or infections. Additionally, a skin biopsy might be recommended to rule out other skin disorders. By combining these methods, healthcare providers can effectively diagnose chronic hives and develop an appropriate treatment plan.
- Diagnosis of chronic hives typically involves a detailed medical history to identify triggers and patterns of symptoms.
- A physical examination may be conducted to assess the extent and appearance of hives on the skin.
- Blood tests may be ordered to check for underlying conditions such as thyroid disorders or autoimmune diseases.
- Allergy testing may be recommended to determine if specific allergens are causing the hives.
- In some cases, a skin biopsy may be performed to rule out other skin conditions that may mimic hives.
- Keeping a detailed diary of symptoms and potential triggers can also aid in the diagnosis of chronic hives.
Treatment for Chronic Hives (Urticaria)
Chronic hives, or urticaria, can be managed through various treatment options aimed at alleviating symptoms and identifying underlying causes. Antihistamines are commonly prescribed to reduce itching and hives. For more severe cases, corticosteroids or other anti-inflammatory medications may be recommended.
In cases where an underlying trigger is identified, such as an allergy or autoimmune condition, addressing the root cause is crucial. Lifestyle modifications, stress management techniques, and avoiding known triggers can also help in managing chronic hives. In some instances, a referral to an allergist or immunologist may be necessary for further evaluation and specialized care.
