By: Ovation Obstetrics & Gynecology:
Asthma and Allergies Awareness Month is an important time to highlight how respiratory and immune conditions uniquely affect women. While many people think of allergies and asthma as purely environmental or genetic conditions, there is another key factor that often goes unrecognized: hormones.
At Ovation OB/GYN, we take a whole-body approach to women’s health—recognizing that hormonal fluctuations can influence everything from mood and metabolism to immune response. For women with allergies or asthma, understanding this connection can be a powerful step toward better symptom management and overall well-being.
“Dr. Vu is the absolute best physician I’ve ever had. She is so personal and answers every question with honesty and care. I just had my second baby, first delivery with Dr. Vu and my second C section was a redemption story! So grateful I was in her care and guidance every step of the way, she also had an outstanding team that also supported and cared alongside her every step of the way. I feel so lucky to have been her patient as every step of the way I felt cared for, heard and confident. She is not only a brilliant doctor but truly cares!”

Why Allergies and Asthma Can Be Different for Women
Asthma and allergies are both inflammatory conditions driven by the immune system. When the body encounters a trigger—like pollen, dust, or pet dander—it reacts by releasing chemicals such as histamine, leading to symptoms like sneezing, congestion, wheezing, and shortness of breath.
However, research shows that women are more likely than men to experience more severe asthma in adulthood. In fact, asthma prevalence and severity are higher in women, and this difference is strongly linked to sex hormones like estrogen and progesterone. (PMC)
Hormones don’t just regulate reproduction—they also interact with the immune system. Estrogen receptors are found on immune cells, meaning hormonal changes can directly influence how the body responds to allergens and inflammation. (PMC)
How Hormones Affect the Immune System
Hormones—especially estrogen—play a complex role in allergic disease. Studies show that estrogen can “skew” the immune system toward an allergic response by increasing the production of immunoglobulin E (IgE) and promoting inflammation. (PMC)
This means that when estrogen levels fluctuate, your body may become more sensitive to allergens. Hormonal changes can:
- Increase airway inflammation
- Heighten sensitivity to environmental triggers
- Affect mucus production and lung function
- Influence how strongly your immune system reacts
These effects help explain why some women notice that their allergy or asthma symptoms seem to come and go—or worsen—at certain times.
Hormonal Life Stages That Can Impact Symptoms
Throughout life, women experience significant hormonal shifts that can influence asthma and allergy symptoms.
- The Menstrual Cycle
Many women notice that their symptoms worsen before or during their period. This is often referred to as “perimenstrual asthma.” Hormonal fluctuations—particularly changes in estrogen and progesterone—can trigger increased airway inflammation and sensitivity. (PMC) - Pregnancy
Pregnancy brings dramatic hormonal changes, and asthma symptoms may improve, worsen, or stay the same depending on the individual. The immune system shifts during pregnancy can also affect how the body responds to allergens. - Perimenopause and Menopause
As hormone levels fluctuate and eventually decline, many women experience changes in respiratory symptoms. Some may develop new allergies or notice worsening asthma during this time. - Hormonal Medications
Birth control or hormone replacement therapy (HRT) can also influence symptoms. Because these treatments alter hormone levels, they may affect inflammation and immune response in different ways.
Overall, key life stages such as puberty, menstruation, pregnancy, and menopause are all associated with changes in asthma symptoms, reinforcing the strong link between hormones and respiratory health. (Asthma + Lung UK)
The Estrogen–Asthma Connection
Estrogen is one of the most studied hormones in relation to asthma and allergies. It can affect multiple systems involved in breathing and immune response.
Research suggests that estrogen may:
- Promote airway inflammation
- Influence lung function and airway sensitivity
- Affect how immune cells respond to allergens
- Contribute to more severe or persistent asthma symptoms
Additionally, fluctuations—not just high or low levels—appear to play a significant role. Rapid hormonal changes may trigger symptom flare-ups, making asthma and allergies feel more unpredictable. (PMC)
Why Symptoms Can Feel Unpredictable
One of the most frustrating aspects of hormone-related asthma and allergies is how inconsistent symptoms can be.
You might notice:
- Seasonal allergies that feel worse some months than others
- Asthma flare-ups that align with your cycle
- New sensitivities that develop during perimenopause
- Symptoms that change with stress, sleep, or lifestyle factors
This variability is often due to the dynamic relationship between hormones and the immune system. Hormonal shifts can amplify the body’s inflammatory response, making reactions stronger—even to triggers that previously caused only mild symptoms. (msmedicine.com)
Managing Hormone-Related Allergy and Asthma Symptoms
The good news is that understanding the hormonal connection can help you take a more proactive approach to managing symptoms.
Track Your Symptoms
Keeping a journal of your symptoms alongside your menstrual cycle or life changes can help identify patterns. This information can be valuable for both diagnosis and treatment.
Work with Your Healthcare Team
Managing asthma and allergies often requires a coordinated approach. Your OB/GYN and primary care provider or allergist can work together to tailor a plan that considers both hormonal and respiratory factors.
Maintain Consistent Treatment
If you’ve been prescribed inhalers, antihistamines, or other medications, consistency is key. Hormonal fluctuations may make symptoms feel unpredictable, but regular treatment can help stabilize your condition.
Support Overall Hormonal Health
Lifestyle factors such as sleep, stress management, and nutrition can influence hormone balance—and, in turn, immune function. Small changes can make a meaningful difference.
Discuss Hormonal Therapies Carefully
If you are considering birth control or hormone replacement therapy, talk with your provider about how these treatments may affect your asthma or allergies. Individual responses can vary, so personalized care is essential.
“I was a new patient who came to Dr Keys for my first pregnancy. I only have good things to say about Dr. Keys, she is great and explains things well. She answered all my questions. I was very comfortable with her. The whole pregnancy experience with her and her staff was amazing.”

A Whole-Person Approach to Women’s Health
At Ovation OB/GYN, we understand that women’s health is interconnected. Hormones don’t operate in isolation—they influence nearly every system in the body, including the immune and respiratory systems.
Asthma and allergies are not just about environmental triggers. For many women, they are also shaped by hormonal changes that occur throughout life.
This Asthma and Allergies Awareness Month, take time to consider how your body responds to these changes. If you’ve noticed patterns in your symptoms or feel like your allergies or asthma are becoming harder to manage, you’re not imagining it—and you’re not alone.
With the right support, education, and personalized care, you can better understand your body and take control of your symptoms—so you can breathe easier in every stage of life.
