Do hormonal changes cause asthma flare-ups in a 34-year-old?

Question

Hello doctor,

I am a 34-year-old woman with long-standing asthma, and I am worried about how it may affect my reproductive health. I use inhalers daily, and sometimes need steroid tablets during flare-ups.

Will long-term steroid use impact my fertility or cause irregular periods?
I am also planning for pregnancy, but I worry about whether asthma attacks or medications could harm the baby. Is it safe to continue inhalers throughout pregnancy, or are there specific ones I should avoid?
I have heard that uncontrolled asthma can increase the risk of preeclampsia or low birth weight. How can I minimize those risks?
In terms of contraception, are there any methods that might worsen asthma symptoms, especially hormonal ones?
Do women with asthma face more severe symptoms during menopause, since hormone changes may affect breathing?

Please suggest.

Thank you.

Hello,

Welcome to icliniq.com.

I have read your query and understand your concern.

Asthma itself does not usually affect fertility, but repeated systemic steroid use can sometimes disturb periods if doses are high and prolonged. Inhalers are generally safe and are preferable to the risk of uncontrolled asthma in pregnancy. Stopping or reducing them on your own is more dangerous. Minimize risks by keeping asthma stable before conception. Get flu and pertussis vaccines.

During pregnancy, well-controlled asthma is the key because poorly controlled asthma can raise risks like preeclampsia, preterm birth, and growth restriction. Most standard inhalers (ICS (inhaled corticosteroids) and beta-agonists) are safe; the only thing is to avoid unnecessary high-dose systemic steroids unless a flare-up demands it.

The probable diagnosis is menstrual irregularities caused by steroid bursts, not asthma itself. If cycles are irregular, do pulmonary function testing, routine pre-pregnancy laboratories, and a thyroid check. The differential diagnoses are steroid-induced menstrual disturbance, PCOS (polycystic ovarian syndrome), and thyroid disorder. For contraception, do not use specific worsening with pills or IUDs (intrauterine devices). Estrogen-containing pills can rarely worsen asthma in some women, but it is not a major issue. Copper IUD (intrauterine device) is neutral. In menopause, some women notice asthma worsening with hormone changes, but it is unpredictable.

Avoid triggers.
Maintain inhaler use.
Have good pre-pregnancy lung control.
Get vaccines up to date,
Keep up regular exercise.
Keep BMI (body mass index) healthy.

Please share which inhalers you are on, so I can tell you exactly about safety in pregnancy. Also, let me know how often you need oral steroids. It is important to plan before trying for a pregnancy.

I hope this answers your query.
