As springtime pollen allergies approach, North Texas residents with seasonal allergies may experience increased symptoms.
Dr. Deepika Kumaresan, an internal medicine doctor with Baylor Scott & White, spoke with Community Impact about allergies in Dallas-Fort Worth, including symptoms, most prevalent allergens and treatment.
What are allergies, and what does the average person need to know about them?
Allergies occur when the body’s immune system overreacts to substances that are typically harmless—like pollen, dust, mold or pet dander. When exposed, the immune system releases chemicals such as histamine, which trigger symptoms ranging from sneezing and itchy eyes to more serious reactions. Understanding your triggers and recognizing symptoms early helps you manage allergies effectively.
What time of year are allergies most prevalent, and why?
In Texas—and especially North Texas—seasonal allergies can occur nearly year‑round due to our climate and plant diversity.
- Winter (December-February): Cedar pollen is the main culprit.
- Spring (February-May): Tree pollens such as oak and pecan dominate.
- Summer (April-September): Grass pollen peaks.
- Fall (August-November): Ragweed surges until the first frost.
Rising temperatures and longer growing seasons have also intensified pollen counts over time.
Which allergens are most prevalent in North Texas?
North Texas experiences a high burden of airborne allergens throughout the year. The most common include:
- Tree pollens: oak, pecan, cedar, elm
- Grass pollens: Bermuda and Johnson grass
- Weeds: ragweed, especially in the fall
These allergens collectively make Dallas-Fort Worth one of the most challenging regions in the U.S. for allergy sufferers.
What are common symptoms of allergies?
Symptoms often depend on how someone is exposed to the allergen, but typical signs include:
- Sneezing
- Runny or stuffy nose
- Itchy, watery eyes
- Coughing or wheezing
- Skin irritation or hives
- In some cases, swelling of the face or throat
Severe reactions—known as anaphylaxis—are rare but require immediate medical attention.
How should people treat them?
Allergies can be challenging, but you don’t have to figure it out on your own. The right care team can help you develop a personalized plan to finally get them under control. Common treatments include over-the-counter antihistamines, nasal corticosteroid sprays and decongestants for short-term relief. Environmental controls—such as keeping windows closed, using air conditioning and regularly cleaning indoor spaces—can also help reduce exposure.
Baylor Scott & White offers a virtual-first allergy care program through the MyBSWHealth app, allowing patients to consult with a provider from home to discuss symptoms, treatment options and medication management. Starting treatment early, often before peak allergy season, can help reduce symptom severity and improve quality of life.
