A drug allergy occurs when your immune system reacts to a medication. A number of drugs can cause a drug allergy, including prescription and over-the-counter medications. The most common signs of a drug allergy are hives, rash or fever. You can have an allergic reaction to a drug even if it caused no reaction in the past.
Food allergy is an immune system reaction that occurs soon after eating a certain food. Even a tiny amount of the allergy-causing food can trigger signs and symptoms such as digestive problems, hives or swollen airways. Food allergy affects an estimated 6 to 8 percent of children under age 3, and about 4 percent of adults. While there’s no cure, some children outgrow their food allergy as they get older. It’s easy to confuse a food allergy with a much more common reaction known as food intolerance. While bothersome, food intolerance is a less serious condition that does not involve the immune system.
Cow’s milk is one of the most common allergy-causing foods in children, and it’s the leading cause of allergic reactions in very young children. Milk allergy affects about 2 percent to 3 percent of infants worldwide, and its signs and symptoms can be serious enough to cause distress not just for an allergic child, but also for the child’s family. Most children outgrow a milk allergy by age 2 or 3. It’s important to differentiate a true milk allergy from milk protein intolerance or lactose intolerance. Unlike a milk allergy, intolerance doesn’t involve the immune system. Milk intolerance causes different symptoms and requires different treatment than does a true milk allergy. Common signs and symptoms of milk protein or lactose intolerance include digestive problems, such as bloating, gas or diarrhea, after consuming milk.
Spring means flower buds and blooming trees — and for the millions of people who have springtime allergies, it means sneezing, congestion, runny nose and other signs and symptoms. In the early spring, the major culprit is wind-borne pollen from trees. In late spring, grasses start to cause trouble. The worst springtime allergy signs and symptoms occur during hot, dry or windy days when there’s a lot of pollen and mold in the air.
But before you settle for plastic flowers and artificial turf, try these simple and effective strategies. You can’t completely avoid springtime allergies — but you can reduce your signs and symptoms by being prepared. Here are some tips that can help.
Reduce your exposure to pollen
There are a number of things that you can do to reduce your exposure to your allergy triggers:
- Stay indoors on dry, windy days — the best time to go outside is after a good rain, which helps clear pollen from the air. Continue reading About Springtime allergies
Hay fever, also called allergic rhinitis, causes cold-like symptoms such as a runny nose, congestion, sneezing and sinus pressure. But unlike a cold, hay fever isn’t caused by a virus — it’s caused by an allergic response to indoor or outdoor airborne allergens, such as pollen, dust mites or pet dander. Some people have hay fever year-round. For others, hay fever gets worse at certain times of the year, usually in the spring, summer or fall. One of the most common allergic conditions, hay fever affects about one in five people.
For some people hay fever symptoms are a minor, temporary nuisance. But if your symptoms are more persistent, they can make you miserable and affect your performance at work, school or leisure activities. Finding the right hay fever treatment probably won’t completely eliminate your symptoms — but for most people, it makes a big difference.
Signs and symptoms of hay fever usually develop immediately after you’re exposed to specific allergy-causing substances (allergens) and can include: Continue reading About Hay Fever
