Allergies occur when the body has a hypersensitive reaction to a substance that is actually harmless. The reason for this is a malfunction of the body's own defense system against disease - the immune system. It can cause you to sneeze or have a runny or stuffy nose. Allergies also often cause skin rashes and itching, red or watery eyes. However, even more severe reactions can occur, such as allergic shock or allergic asthma. There are many different types of allergies. Common triggers include pet dander, dust, mold, preservatives, medications, cosmetics, metals, or food. Hay fever is an allergy to pollen from plants. Allergic reactions can vary in severity. Some allergies exist from birth, others develop later in life. Infants who are breastfed for a longer time seem to develop allergies less often than babies who are weaned early.
Allergies can improve or worsen during pregnancy. It's best to avoid any substances you're allergic to. This is often possible with animal hair, house dust and cigarette smoke. With hay fever, on the other hand, it is difficult to avoid the pollen that triggers the allergy. Sometimes it helps to rinse your nose with a saline solution. Often, however, this is not enough. That is why many allergy sufferers take medications that slow down the immune system when needed, making the allergy becomes tolerable. These medications are called. They are available as tablets, nasal sprays, ointments and as inhalers. Before you take any of these medicines, you should talk to your doctor.

Instead, your doctor can take a blood sample and test it to see if it contains antibodies that trigger an immune overreaction.
