Tipos de ronchas en la piel fotos refers to types of hives on the skin photos. Hives are the itchy and raised welts on the skin, also known as urticaria. These itchy and raised welts are typically flesh-colored, pink, or red on lighter skin and may be slightly lighter or darker than the skin tone or flesh-colored on black or brown skin.
In most cases, hives remain caused by an allergic reaction to food or medicines or because of the response of an irritant in your surroundings. Sometimes, these hives also hurt or sting a person.
In most cases, hives are acute (temporary) problems and can also be treated by taking allergic medicine, and most of these rashes disappear independently. Though chronic (ongoing) cases and hives accompany a severe allergic reaction, larger medical concerns remain.
What causes hives?
Hives remain typically caused by an allergic reaction to something you have triggered or swallowed. When you have an allergic reaction, your body releases histamines into your blood. Histamines remain chemicals your body produces to defend itself against infection and other outside intruders.
What are the types of hives?
Hives remain caused due to an allergic reaction or may not have a known reason.
Allergic reactions
Allergic reactions are the most common causes of hives. Any allergen can trigger these you might be sensitive to; they are as follows:
- Dust mites
- Insect bites or stings
- Foods (such as nuts, milk, and eggs)
- Pet dander
- Pollen
- Medications (primarily antibiotics, ibuprofen, or cancer drugs.)
Anaphylaxis
Anaphylaxis is an intense, deadly allergic reaction. In this state, hives are often accompanied by nausea or vomiting, difficulty breathing, dizziness, and severe swelling. If you are experiencing anaphylaxis, call 911 or your local emergency services immediately.
Chronic (long-lasting) hives
Chronic hives are continuing cases that don’t essentially have an identifiable cause. Also termed chronic urticaria, this condition is marked by frequent hives that can affect your daily life and can last from weeks to numerous months or even some years.
You may have chronic hives if you have welts that don’t go away within six weeks. It is not life-threatening, but this form of hives can be painful and difficult to treat. Chronic hives may also remain a symptom of a primary health problem, such as:
- Celiac disease
- An autoimmune disorder
- Lupus
- Thyroid disease
- Type 1 diabetes
- Rheumatoid arthritis
Dermatographism
A dermatographism is a form of a mild, temporary hive. Extreme itching or constant pressure on the skin are the reasons for it. Dermatographism usually clears up on its own in a short period without treatment.
Temperature-induced hives
Sometimes, temperature changes can induce hives in people who are sensitive to such changes. Cold-induced hives may arise from cold water or air exposure, whereas body heat from physical activity may cause exercise-induced hives. Tanning beds or exposure to sunlight may also bring about solar hives in some persons.
Infection-induced hives
Both bacterial and viral infections can cause hives. Urinary tract infections and strep throat are the causes of common bacterial infections. Viruses that cause infectious mononucleosis (mono), colds, and hepatitis cause hives frequently.
Treatment options
The first step in getting treatment is determining if you have hives. In most cases, a doctor can evaluate it through a physical exam. Your skin will display signs of the welts that are related to hives.
A doctor may also do skin or blood tests to determine the reason for your hives — specifically if an allergic reaction causes them.
You may not require prescription treatment if you suffer a mild case of hives unrelated to health conditions or allergies. In these circumstances, a doctor might advise that you find temporary relief by:
- Taking antihistamines, such as cetirizine (Zyrtec) or diphenhydramine (Benadryl)
- Avoiding hot water, which may worsen the hives
- Avoiding irritating the area
- Take a cool or lukewarm bath with baking soda or colloidal oatmeal.
Anaphylaxis remains a medical emergency that must be treated immediately by a physician. Contact 911 or your nearby emergency services if you are experiencing anaphylaxis.
