Overview
In this section you will get an overview of the condition and its relevance to your health.
Hay fever -- medically known as allergic rhinitis -- is one of the most common allergic conditions. Millions of people suffer seasonally or year-round from typical symptoms such as sneezing, runny nose, and itchy eyes.
The symptoms are often underestimated or dismissed as a harmless cold. Left untreated, however, hay fever can significantly impair quality of life and increase the risk of developing asthma.
The good news: hay fever can be treated very effectively today. Modern medications can relieve symptoms efficiently -- including after medical review as part of an online consultation.
What is it?
Here you will learn what medically characterizes this condition and how it is defined.
Hay fever is an allergic reaction of the immune system to normally harmless substances from the environment, known as allergens. Common triggers include pollen from grasses, trees, or herbs, as well as house dust mites or animal dander.
When the body comes into contact with the allergen, it releases histamine. This chemical messenger causes the typical allergic symptoms such as mucosal swelling, itching, and increased mucus production.
Depending on the trigger, a distinction is made between seasonal hay fever (pollen allergy) and perennial allergic rhinitis.
Causes
The following information explains which factors can contribute to the development of this condition.
The cause of hay fever is a malfunction of the immune system.

Treatment
Here the available therapy options and their modes of action are explained.
The treatment of hay fever depends on the type and severity of symptoms.
Antihistamines block the effects of histamine and relieve itching, sneezing, and runny nose. Modern preparations usually do not cause drowsiness.
Corticosteroid nasal sprays have a strong anti-inflammatory effect and are particularly effective for nasal congestion.
Other treatment options:
- Eye drops for eye symptoms
