The Link Between Allergies and Asthma: What You Need to Know

Allergies and asthma are two of the most common respiratory conditions, and they are often closely linked. In fact, many people who suffer from asthma also have allergies. According to the Asthma and Allergy Foundation of America, about 60% of people with asthma have allergic asthma, which is triggered by allergens such as pollen, dust mites, and animal dander. In this article, we will explore the link between allergies and asthma, and what you need to know about managing these conditions.

Understanding Allergies

Allergies are a common condition that affects millions of people worldwide. They occur when the immune system overreacts to a substance that is usually harmless, such as pollen, dust mites, or certain foods. The immune system produces an antibody called immunoglobulin E (IgE), which triggers the release of histamine and other chemicals in response to the allergen. These chemicals cause the symptoms of an allergic reaction, such as sneezing, runny nose, itchy eyes, and skin rashes.

Allergies can be seasonal, such as hay fever, or year-round, such as those caused by dust mites or animal dander. Some people may also experience allergic reactions to certain foods, insect bites, or medications.

Understanding Asthma

Asthma is a chronic respiratory condition that affects the airways. It causes inflammation and narrowing of the airways, making it difficult to breathe. Symptoms of asthma include wheezing, coughing, chest tightness, and shortness of breath. Asthma attacks can be triggered by various factors, including exercise, cold air, pollution, and allergens.

There are several different types of asthma, including allergic asthma, non-allergic asthma, exercise-induced asthma, and occupational asthma. Allergic asthma is the most common type of asthma, and it often starts in childhood.

The Link Between Allergies and Asthma

Allergic asthma is a type of asthma that is triggered by allergens. When a person with allergic asthma is exposed to an allergen, their immune system overreacts, causing inflammation and narrowing of the airways. This can lead to asthma symptoms such as wheezing, coughing, and shortness of breath.

The link between allergies and asthma is well established, and many people who suffer from allergies also have asthma. In fact, the two conditions often occur together, and people with allergies are more likely to develop asthma than those without allergies. Studies have shown that exposure to allergens can worsen asthma symptoms and increase the risk of asthma attacks.

Managing Allergies and Asthma

Avoiding Triggers

The first step in managing allergies and asthma is to identify and avoid triggers. This may involve making changes to your environment, such as using air filters, keeping your home clean, and avoiding exposure to allergens. It may also involve making changes to your diet, such as avoiding certain foods that trigger allergic reactions.

Taking Medications

There are several medications available to treat allergies and asthma. These include antihistamines, decongestants, corticosteroids, and bronchodilators. Your healthcare providor may prescribe one or more of these medications depending on your symptoms and the severity of your condition.

Monitoring Symptoms

It is important to monitor your symptoms and keep track of any changes. This can help you identify triggers and adjust your treatment plan accordingly. You may also want to keep a diary of your symptoms and any medications you take.


Allergies and asthma are two conditions that are closely linked, and managing both requires a comprehensive approach. If you have allergies or asthma, it is important to work with your healthcare providor to develop a treatment plan that is tailored to your needs. With the right care, you can manage your symptoms and live a healthy, active life. By avoiding triggers, taking medications, and monitoring your symptoms, you can reduce the impact that allergies and asthma have on your daily life.
