    Allergies occur when your immune system reacts to a foreign substance — such as pollen, bee venom or pet dander — or a food that doesn't cause a reaction in most people.Your immune system produces substances known as antibodies. When you have allergies, your immune system makes antibodies that identify a particular allergen as harmful, even though it isn't. When you come into contact with the allergen, your immune system's reaction can inflame your skin, sinuses, airways or digestive system.T...

    Allergy symptoms, which depend on the substance involved, can affect your airways, sinuses and nasal passages, skin, and digestive system. Allergic reactions can range from mild to severe. In some severe cases, allergies can trigger a life-threatening reaction known as anaphylaxis.Hay fever, also called allergic rhinitis, can cause: 1. Sneezing 2. Itching of the nose, eyes or roof of the mouth 3. Runny, stuffy nose 4. Watery, red or swollen eyes (conjunctivitis)A food allergy can cause: 1. Ti...

    An allergy starts when your immune system mistakes a normally harmless substance for a dangerous invader. The immune system then produces antibodies that remain on the alert for that particular allergen. When you're exposed to the allergen again, these antibodies can release a number of immune system chemicals, such as histamine, that cause allergy symptoms.Common allergy triggers include: 1. Airborne allergens, such as pollen, animal dander, dust mites and mold 2. Certain foods, particularly...

    You might be more likely to develop an allergy if you: 1. Have a family history of asthma or allergies, such as hay fever, hives or eczema 2. Are a child 3. Have asthma or another allergic condition

    Having an allergy increases your risk of certain other medical problems, including: 1. Anaphylaxis. If you have severe allergies, you're at increased risk of this serious allergy-induced reaction. Foods, medications and insect stings are the most common triggers of anaphylaxis. 2. Asthma. If you have an allergy, you're more likely to have asthma — an immune system reaction that affects the airways and breathing. In many cases, asthma is triggered by exposure to an allergen in the environment...

    Preventing allergic reactions depends on the type of allergy you have. General measures include the following: 1. Avoid known triggers. Even if you're treating your allergy symptoms, try to avoid triggers. If, for instance, you're allergic to pollen, stay inside with windows and doors closed when pollen is high. If you're allergic to dust mites, dust and vacuum and wash bedding often. 2. Keep a diary. When trying to identify what causes or worsens your allergic symptoms, track your activities...

    A rash is a temporary eruption or discoloration of the skin and is often inflamed or swollen. Rashes come in many forms and levels of severity, and they last for different amounts of time. Some common causes of rashes include: 1. Infections — This broad category covers a wide range of illnesses, including: 1. Viral infections, such as measles, rubella, roseola, fifth disease, varicella zoster, herpes or shingles 1. Bacterial infections, such as impetigo, scarlet fever or Lyme disease 1. 1. Fu...

    Although rash is easily recognized, all rashes are not the same. Rashes vary in their appearance, timing, location or distribution, and duration. In general, rashes can be described as: 1. Macular — Flat, red spots 2. Papular — Small, raised, solid bumps 3. Macular and papular — A combination 4. Papulosquamous — A combination of papules and scaly areas 5. Vesicular — Small, raised, fluid-filled blisters Additional signs and symptoms that sometimes accompany rashes include: 1. Fever 2. Swollen...

    Your doctor will ask you about your medical history, including your history of allergies and your work history, to check for possible exposure to chemical irritants or to people with infections. Your doctor also may ask specific questions about your rash, including: 1. When it began — Did the rash appear after you ate a new food, tried a new skin care product or took a new medication? 2. Location and pattern — Does the rash affect only sun-exposed areas or only areas in direct contact with gl...

    How long a rash lasts depends on its cause. However, most rashes usually disappear within a few days. For example, the rash of a roseola viral infection usually lasts 1 to 2 days, whereas the rash of measles disappears within 6 to 7 days. Rashes caused by an antibiotic allergy may last 3 to 14 days, whereas diaper rash almost always clears up within 1 week (if diapers are changed frequently).Rashes resulting from lupus or dermatomyositis may last for an extended period of time.

    Prevention depends on the cause of the rash: 1. Infections — Check that you and your children are up-to-date in your routine immunizations. Wash your hands frequently, bathe regularly and avoid sharing clothing or personal grooming items with other people. To prevent Lyme disease, wear light-colored clothing that contrasts with the dark tick and covers most of your skin when you go into the woods. Use approved tick repellents. Be aware that you are more likely to be exposed to ticks in areas...

    Treatment depends on the cause of the rash: 1. Infections — Bacterial infections are treated with antibiotics. Fungal infections are treated with antifungal medications. Many viral infections that cause rash will go away within several days and require no medication. Less often, antiviral drugs are necessary. 2. Allergic reactions — A severe allergic reaction is a life-threatening medical emergency. It must be treated immediately with epinephrine, a medication that opens narrowed airways and...

    Seek immediate medical attention if you begin to have difficulty breathing or develop hives, a fever, a fast pulse, confusion or nausea. These could be signs of a life-threatening allergic reaction. Always consult your doctor promptly if a rash: 1. Worsens 2. Lasts longer than one week 3. Shows signs of local infection (oozing, redness or swelling of the skin) 4. Occurs together with fever, chills, swollen glands or other symptoms of infection (sore throat, cough, headache, nasal congestion,...

    The outlook for most rashes is excellent, especially after the cause has been identified accurately. In severe allergic reactions, a patient can die within minutes without immediate medical treatment. With proper treatment, recovery usually is complete. However, the patient remains at risk of future severe reactions if he or she is exposed to the same allergy-producing agent. For this reason, a prescription for a self-injection pen containing epinephrine for emergencies usually is recommended...
