How long do hives usually last

Hives (Urticaria)

What are hives?

Hives, or urticaria, are flat red welts that can appear anywhere on the skin and usually itch. Hives often occur as an allergic reaction to something eaten or something that has contacted the skin. Foods, medicines, and plants are common causes, but sun exposure, stress, infections, and autoimmune diseases have also been known to cause hives.

Symptoms include an itchy, stinging pink rash of slightly swollen skin. The rash may wax and wane in severity. Acute hives typically resolve within six weeks, but chronic hives (urticaria) can persist for months or years.

Hives often resolve on their own, especially in children. Otherwise, treatment for acute hives involves oral antihistamine medications to help relieve the itching and stinging. Chronic hives that do not improve with antihistamines may be treated additionally with corticosteroids, antibiotics, and other stronger medicines. A study found that 35% of people with chronic hives, are symptom free within one year, with another 29% having some reduction of symptoms.

You can safely treat this condition on your own as long as you does not develop trouble breathing. Any antihistamine (like Zyrtec, Clarinex, etc) works.

1. What are hives?

Hives are symptoms of an allergic reaction in the form of a swollen rash. Its your bodys way of saying it doesnt like a certain entity. In response to an allergen, immune cells release a protein called histamine, causing blood vessel leakage. The fluid pools beneath your skin, triggering a rash.

Hives are also known as wheals, welts, and urticaria. Lesions are typically pinkish and oval and may be rimmed in red. They range in size from a few millimeters to several inches. The welts are often itchy.

You may also see fluid accumulation beneath your skin. Common sites are the face, neck, arms, hands, legs, feet, and back. The swelling may be accompanied by a burning sensation. Although hives appear alarming, they arent contagious.

2. What causes hives?

To prevent recurrence, you must pinpoint the cause. Possible triggers are:

• insect bites
• allergenic foods
• artificial dyes and additives
• contact with an irritating substance, such as a chemical or latex
• aspirin, antibiotics, blood pressure medications, and non-steroidal anti-inflammatory drugs
• emotional stress
• immune disorder
• infections
• plants and pollen
• pets
• dust mites
• environmental factors

Examples of environmental triggers are scratching and constant pressure from constrictive clothing, like belts and sock elastic. Another cause is extreme cold, such as plunging into a swimming pool. Other physical provocations are sweating, hot water, sun, and exercise.

3. How long do hives last?

The duration of hives depends on the types of hives.

Acute A single episode can linger for up to six weeks, in which case its considered acute. However, most people have symptom resolution in eight to 24 hours.

Chronic When symptoms persist for more than six weeks, urticaria is chronic. The most common cause of longstanding rashes is immune malfunction.

Anaphylaxis This sudden, serious allergic reaction is life-threatening if not treated promptly. In addition to hives, symptoms include:

• hammering heartbeat
• cold, sweaty skin
• nausea and vomiting
• swelling of the lips, tongue, and throat
• difficulty breathing
• feeling lightheaded

Symptoms arise within minutes of allergic contact, requiring emergent medical care. Hospital treatment includes an injection of epinephrine, a synthetic form of the hormone adrenaline. Fortunately, epinephrine quickly resolves the allergic shock.

If anaphylaxis is caused by a food allergy, a second episode can occur one to four hours later. This is why patients may be asked to remain in the hospital for six hours of observance. Once you have an incident, its wise to always carry three doses of epinephrine.

4. Should I see a doctor?

You should visit a doctor if you cant identify the cause of hives or if they continue to recur. Youll likely be asked the following questions:

• When did your episode begin?
• Where did symptoms originate?
• Were you bitten by an insect?
• Have you recently been exposed to animals, chemicals, or latex gloves?
• Are you taking any medications or herbal supplements?
• Is there any other significant medical history?

Your physician may also request that you keep a diary of everything you eat, drink, take as medicine, or contact for two to four weeks.

If symptoms have continued for more than six weeks, an external trigger isnt likely. However, chronic hives can be prompted by allergenic foods, caffeine, and alcohol. If your doctor suspects a reaction to a specific substance, blood tests may be ordered.

5. What factors influence duration?

The time to symptom resolution is determined by:

• the ability to identify the cause
• symptom severity
• treatment effectiveness

6. What are the healing time frames in various circumstances?

Food Allergy

If hives are triggered by a food, symptoms will arise each time you eat the offending substance. Usually, the reaction erupts within a few minutes of consumption.

How long do hives last after an allergic reaction from foods?

Symptoms generally resolve within two hours but can linger for days. Duration depends on the type and amount of food ingested and your sensitivity.

What are the main triggers?

The most common culprits are milk, fish, eggs, wheat, soy, and peanuts. Foods often implicated include apples, berries, cherries, citrus, kiwis, melons, carrots, celery, spinach, and tomatoes. Processed meats and chocolate can trigger histamine release. Alcohol is another offender.

There is no cure for a food allergy. Avoidance is the only remedy. However, allergies that begin in childhood can be outgrown regarding milk, eggs, wheat, and soy. Allergies to peanuts and fish are typically lifelong.

Child Episodes

How long do hives last in children?

In children, episodes tend to emerge within 15 minutes to a few hours. They may arise and subside in waves. For example, welts may first appear on a childs stomach and vanish within an hour, replaced by new ones on their back.

What usually triggers hives in children?

Typical triggers of hives in children are:

• Illness bacterial or viral infection

• Foods fish, peanuts, and berries eaten within the previous 24 hours

• Medication drugs used to treat a cold, fever, and pain

• Irritant soap, shampoo, laundry detergent, fabric softener, suntan lotion, skin cream, clothes, bed sheets, blankets, or playing among bushes and grass

Baby Hives

Weaker immune systems make babies more susceptible to hives. The most common cause is food allergy. Another offender is artificial dye, especially Yellow Number 5. All the above causes of hives also apply.

How long do hives last in babies?

Hives launched by food usually disappear within a few hours. Those rendered by viral infection can last three to five days. Autoimmune disease causes chronic duration. However, breastfeeding strengthens a babys immune system, reducing the likelihood of allergies.

Antibiotics

Hives provoked by antibiotics can arise within minutes of a first dose and up to 10 days after stopping. They can persist for roughly two weeks.

Other implicated medications are aspirin, naproxen, ibuprofen, and ACE-inhibitor blood pressure drugs.

7. What are the best topical remedies for hives?

Aloe Vera

This soothing gel reduces redness, itching, and inflammation. Apply aloe vera gel to affected skin, leave on for 15 minutes, and rinse with warm water. Use as needed until your skin heals.

Baking Soda

To relieve itching and inflammation, soak for 20 minutes in a bath of warm water and one cup of baking soda. Another option is applying a paste. Mix two tablespoons of baking soda with enough water to produce a thick consistency. Apply it to your rash, and leave it on for 10 minutes. Then rinse off with cool water.

Use these two methods as needed for relief (source).

Apple Cider Vinegar

A natural antihistamine, vinegar regulates immune response. Add two cups of apple cider vinegar to a bathtub of warm water and soak for 20 minutes.

Alternatively, mix a solution of one teaspoon of vinegar and one tablespoon of water. Apply the liquid with a cotton ball three times daily (source).

Oatmeal

To relieve itching and heal welts, take a comforting oatmeal bath. Mix two cups of ground oatmeal with one cup of baking soda. Add to a bathtub of warm water. Soak for 20 minutes twice daily for symptomatic relief.

Essential oils

The best essential oils for hives are lavender, peppermint, tea tree and chamomile essential oils. Read this post to learn how to use them for hives.

Other good choices arehelichrysum, myrrh, eucalyptus and oregano essential oils.

8. Dietary modifications toexpedite healing

Avoid Allergens

Becoming a label sleuth will help you avoid allergens. Pass on foods containing additives and preservatives such as dyes, sulfites, and benzoates. The most fail-safe diet consists of unprocessed, organic foods.

Elimination Diet

For two to four weeks, boycott suspect foods. Once symptoms diminish, re-introduce one substance at a time. After eating the food, wait three days and watch for any reactions. If none occur, introduce another food. If symptoms arise, bingo! Youve apprehended a villain.

Anti-Inflammatory Diet

You can both treat and prevent hives with foods rich in Vitamin C, omega-3 fats, quercetin, and bromelain (source).

• Vitamin C This nutrient reduces histamine release and speeds its breakdown. Increase your Vitamin C intake with bell peppers, broccoli, strawberries, and citrus.

• Omega-3 Fats To relieve symptoms and prevent outbreaks, consume walnuts, flaxseeds, and salmon.

• Quercetin This plant pigment suppresses the release of histamine. Potent sources are apples, buckwheat, grapes, green tea, onions, parsley, and sage. If hives are severe, you may take a quercetin supplement.

• Bromelain Complementing quercetins anti-inflammatory effects is bromelain. This enzyme, sourced from pineapple stems, quells inflammation and swelling. If youre in the midst of an outbreak, you may take a bromelain supplement.

• Also associated with the anti-inflammatory diet is reducing intake of refined foods and sugar. Harmful bacteria party hearty on these substances.

• Another caveat concerns omega-6 fats. Although essential for health, excessive amounts rev inflammation, setting the stage for hives. Omega-6 fats are present in vegetable oils such as corn, cottonseed, safflower, sunflower, sesame, soy, margarine, and shortening.
