Eosinophilic asthma is a condition in which an elevated level of eosinophils in the blood increases the likelihood of severe asthma attacks and associated flare-ups. Adults between the ages of 35 and 50 are at an elevated risk of developing this severe subtype of asthma. Additionally, people affected by asthma in childhood are at an increased risk. Here is a brief overview of causes and risk factors, known symptoms, and treatments for the condition:

Causes
While the precise cause of asthma is not yet known, studies indicate the following risk factors can severely increase the risk of developing asthma among adults:

• Parasitic infections
• Side effects of certain treatment options can trigger asthma and cause inflammation with recurring flare-ups
• Seasonal allergies and eczema
• Elevated levels of eosinophils (white blood cells) in the blood can trigger a condition called eosinophilic esophagitis resulting in respiratory problems
• Other conditions like cancer and respiratory failures linked to asthma can trigger an abnormal concentration of eosinophils in the blood

Symptoms
Respiratory problems are the first signs of eosinophilic asthma, and one should also look out for the following symptoms:

• A chronic cough and asthma-like symptoms that affects regular breathing
• A runny nose triggered by common seasonal allergies
• Chest tightness, shortness of breath, and continued wheezing
• Airflow obstruction due to lung problems
• Visible rashes and urge to itch persistently
• Diarrhea due to underlying parasitic infections

Nutritional choices
For any type of asthma, doctors suggest avoiding foods that can trigger an intolerance and worsen associated symptoms. These items include milk, eggs, wheat, soy, seafood, and nuts like peanuts and tree nuts. Triggering foods can vary depending on the intensity of the symptoms. A healthy nutritional regimen for people with asthma can consist of foods rich in antioxidants to counter inflammation; vitamins A, C, and E to boost immunity; other essential minerals that can manage immune system responses.

Natural remedies
Mild to moderate asthma symptoms can be managed by making simple lifestyle changes. Improved cardiovascular activity helps keep the lungs strong and improves breathing function. This can help overcome mild to moderate discomfort and help one get the most out of the ongoing treatment. One should ensure all vaccinations are up to date to lower the risk of contracting infections like the flu. One should also limit contact with pets so that common allergens like pet dander, dust mites, and debris do not trigger a flare-up. Additionally, any abrupt changes in the weather can trigger symptoms. Doctors advise proper protection and avoiding unnecessary exposure to elements that can trigger asthmatic attacks.

Treatment options
Prescription options and inhalers are the primary treatment options to treat eosinophilic asthma. The prescriptions help prevent the cells in the lungs from releasing certain compounds that can trigger eosinophilic asthma flare-ups and worsen existing symptoms. These options are generally available in the form of an oral pill. Those who do not benefit from varying doses of these prescriptions may be prescribed fast-acting inhalers that help open up airways and ease breathing. Commonly known as bronchodilators, these inhalers are available in varying doses. In addition to the primary treatment, doctors may even suggest using leukotriene modifiers that counter the inflammation in the respiratory tract. Additionally, doctors may recommend biologics that are administered intravenously to counter the inflammation in the lungs.
