Urticaria
Urticaria, commonly known as hives, is a skin condition that is characterized by raised, red, itchy welts on the skin. It is caused by an allergic reaction to certain triggers, such as food, medications, or environmental factors. Urticaria can be acute or chronic, and can last anywhere from a few minutes to several weeks. It is estimated that up to 20% of people will experience urticaria at some point in their lives.
Causes of Urticaria
Urticaria is caused by an allergic reaction to certain triggers, such as food, medications, or environmental factors. Common triggers include pollen, dust mites, animal dander, insect bites, and certain foods. In some cases, the cause of urticaria is unknown.
Diagnosis of Urticaria
Urticaria is usually diagnosed based on a physical examination and a review of the patient's medical history. In some cases, additional tests may be necessary to determine the cause of the condition. These tests may include blood tests, skin tests, or an allergy test.
Complications of Urticaria
In some cases, urticaria can lead to complications, such as angioedema, which is a swelling of the deeper layers of the skin. In rare cases, urticaria can also lead to anaphylaxis, which is a life-threatening allergic reaction.
Prevention of Urticaria
The best way to prevent urticaria is to avoid known triggers. If a trigger is identified, it is important to avoid contact with it. It is also important to practice good skin care, such as avoiding harsh soaps and using a moisturizer to keep the skin hydrated.
Symptoms
- Itchy, red, raised bumps on the skin (hives)
- Swelling of the face, lips, tongue, or throat
- Wheezing or difficulty breathing
- A feeling of tightness in the chest
- Anxiety or a feeling of impending doom
- Nausea, vomiting, or diarrhea
- A drop in blood pressure
If you experience any of these symptoms, it is important to seek medical attention right away. Your doctor can help diagnose the cause of your urticaria and recommend the best treatment plan for you.
Causes
Allergens
Allergens are the most common cause of urticaria. These can include foods, pollen, animal dander, and certain medications. If you have an allergy to any of these substances, you may experience an allergic reaction that causes hives.
Infections
Infections, such as the common cold, can also cause urticaria. This is because the body's immune system is trying to fight off the infection, which can cause an allergic reaction.
Physical Stimuli
Physical stimuli, such as heat, cold, pressure, or sunlight, can also cause urticaria. This is because the body's immune system is trying to protect itself from the stimulus, which can cause an allergic reaction.
Stress
Stress can also cause urticaria. This is because the body's immune system is trying to protect itself from the stress, which can cause an allergic reaction.
Autoimmune Disorders
Autoimmune disorders, such as lupus or rheumatoid arthritis, can also cause urticaria. This is because the body's immune system is attacking its own tissues, which can cause an allergic reaction.
Getting a Diagnosis
Physical Examination
The first step in diagnosing urticaria is a physical examination. During this examination, your doctor will look for signs of hives, such as raised welts, redness, and swelling. They may also take a sample of the affected area to test for allergens or other triggers.
Skin Prick Test
A skin prick test is a common method used to diagnose allergies. During this test, a small amount of an allergen is placed on the skin and then pricked with a needle. If the skin reacts with a raised welt, it is likely that the person is allergic to the allergen.
Blood Tests
Blood tests can be used to measure the levels of certain antibodies in the blood. These antibodies are produced when the body is exposed to an allergen or other trigger. By measuring the levels of these antibodies, doctors can determine if the person is allergic to a particular substance.
Patch Tests
Patch tests are used to diagnose contact allergies. During this test, a small amount of an allergen is placed on the skin and then covered with a patch. If the skin reacts with a raised welt, it is likely that the person is allergic to the allergen.
Conclusion
Diagnosing the cause of urticaria can be difficult, as there are many potential triggers. However, by using physical examinations, skin prick tests, blood tests, and patch tests, doctors can determine the cause of the hives and provide the appropriate treatment.

Treatment
Antihistamines
Antihistamines are the most common treatment for urticaria. They work by blocking the action of histamine, a chemical released by the body during an allergic reaction. Antihistamines can be taken orally or applied topically to the affected area. Common antihistamines include diphenhydramine (Benadryl), cetirizine (Zyrtec), and loratadine (Claritin).
Corticosteroids
Corticosteroids are a type of medication that can be used to reduce inflammation and itching associated with urticaria. They are usually taken orally, but can also be injected or applied topically. Common corticosteroids include prednisone, methylprednisolone, and hydrocortisone.
Immunosuppressants
Immunosuppressants are medications that suppress the immune system. They can be used to treat chronic urticaria, which is caused by an overactive immune system. Common immunosuppressants include cyclosporine, azathioprine, and mycophenolate mofetil.
Light Therapy
Light therapy, also known as phototherapy, is a treatment that uses ultraviolet light to reduce inflammation and itching associated with urticaria. It is usually done in a doctor's office or at home with a special light box. Light therapy is generally safe, but can cause skin irritation or sunburn.
Alternative Treatments
There are also a variety of alternative treatments that may help relieve the symptoms of urticaria. These include acupuncture, herbal remedies, and dietary changes. It is important to talk to your doctor before trying any alternative treatments.
Drugs & Medications
Antihistamines
