Can Menopause Make Allergies Worse? Hormones, Asthma and Allergic Symptoms

Possibly. Estrogen and progesterone influence immune cells involved in allergy, including mast cells, which release histamine. A 2026 review concludes menopause may worsen existing allergic conditions or trigger new ones, including asthma. However, research is limited, and studies on whether HRT helps or harms conflict. New breathing symptoms or severe allergic reactions always need medical assessment.

How strong is the evidence? Limited and mixed. The link is plausible, but not well studied.

What might you notice?

• Hay fever or nasal symptoms that are new or worse
• New or worse asthma: cough, wheeze, chest tightness, breathlessness
• Hives (itchy raised welts) or itchy skin. See itchy skin.
• Reactions to foods, medicines or products you previously tolerated
• Itchy, watery eyes. See dry eyes.

How might hormones affect allergies?

Allergic reactions involve immune cells such as mast cells, which release histamine and other chemicals. The 2026 Frontiers in Allergy review explains that estrogen and progesterone modulate mast cells, a type of allergic inflammation, and how "leaky" blood vessels are. As these hormones fluctuate and fall, allergic conditions may change. Clinical observations suggest menopause may worsen existing conditions or trigger new ones.

The authors emphasize that the research is largely based on small studies and case reports, and that guidelines for managing allergic disease in menopausal women are lacking.

Asthma and menopause

• New-onset asthma. A longitudinal study of European women found new asthma was more common in perimenopausal and postmenopausal women than in women of reproductive age. The 2026 review notes the risk appears higher after surgical menopause, and that body weight partly explains the link. See surgical menopause and weight changes.
• HRT and asthma: mixed evidence. A large UK national cohort study found that current HRT use was associated with up to a 22% lower risk of developing asthma, with lower risk for longer use. A Swedish case-control study found no clear effect. Some other studies suggest increased risk or severity. HRT isn’t used to treat or prevent asthma.

Other causes to consider

• New allergens, such as a new pet, home, workplace or products
• Medicines, including some blood pressure medicines (ACE inhibitors can cause cough and swelling) and anti-inflammatories, which can worsen asthma in some people
• Acid reflux, which can cause cough
• Heart conditions, which can cause breathlessness
• Chronic hives, which can have many causes, including thyroid disease
• Skin dryness, which can mimic allergy. See itchy skin.

See perimenopause or something else.

What will a clinician assess?

A clinician will ask about symptoms, triggers, timing, medicines and family history. For breathing symptoms, they may measure your lung function (spirometry or peak flow). Allergy tests, such as skin prick or blood tests, may be arranged, and chronic hives may prompt blood tests.

What helps?

• Standard treatments work: antihistamines, nasal steroid sprays, eye drops, and inhalers for asthma. They’re effective regardless of menopause stage.
• Identify and reduce triggers, such as pollen, dust, pets or fragrances.
• Review your medicines with your clinician.
• Keep asthma under review, with an up-to-date action plan.
• Maintain a healthy weight, which can help asthma control.
• Tell your clinician if symptoms changed when you started or stopped HRT.

Allergy and asthma symptoms can disturb sleep, which can make other menopause symptoms feel worse. See sleep problems.

Keeping an allergy and symptom diary

For a few weeks, note:

• Symptoms, such as sneezing, cough, wheeze, hives or itching, and their severity
• Where you were and what you were exposed to, such as pollen, pets, foods or products
• Where you are in your cycle, if you still have periods
• Any changes in HRT or other medicines
• Sleep and stress

This helps identify triggers and any link with hormonal changes.

Talking to your doctor about HRT and asthma

If you have asthma and are considering HRT, or your breathing changed after starting or stopping HRT, tell your doctor. The evidence is mixed, so decisions are individual. Your asthma treatment should be reviewed if symptoms change.

When should you get help?

Book an appointment if allergies or breathing symptoms are new, worsening or affecting your life.

Call emergency services immediately if you have:

• Swelling of the lips, tongue, face or throat
• Difficulty breathing or swallowing, or wheezing that doesn’t respond to your inhaler
• Feeling faint, dizzy or confused after a possible allergen

Use an adrenaline (epinephrine) auto-injector if you’ve been prescribed one.

See a clinician promptly if you have:

• A new cough, wheeze or breathlessness
• Hives lasting more than six weeks
• A reaction to a food or medicine you previously tolerated

Questions to ask

1. Could my new or worse allergies be linked to menopause?
2. Should I have allergy tests or lung function tests?
3. Could any of my medicines be contributing?
4. Could HRT affect my asthma or allergies?
5. Do I need an asthma action plan?

Frequently asked questions

Can menopause cause new allergies?

Research suggests hormonal changes may trigger new allergic conditions or worsen existing ones, but evidence is limited.

Can menopause cause asthma?

New-onset asthma appears more common around and after menopause, particularly after surgical menopause.

Does HRT make asthma better or worse?

Studies conflict. A large UK study found lower asthma risk with HRT, while other studies show no effect or higher risk.

Do antihistamines work the same after menopause?

Yes. Standard allergy treatments work at any stage of life.

Can menopause cause hives?

Some women report new or worse hives around menopause, and hormone changes affect mast cells. Chronic hives have many causes, so they should be assessed.
