During pregnancy, managing asthma becomes critical as it can impact both the mother’s health and the baby’s development. A common concern among pregnant women is whether pregnancy can make asthma worse. Understanding the relationship between asthma and pregnancy can help expectant mothers take the necessary steps to ensure a healthy pregnancy.
How pregnancy affects asthma?
1. Hormonal changes:
- Pregnancy brings about significant hormonal changes that can influence asthma symptoms.
- Some women may experience worsened asthma due to increased levels of progesterone and oestrogen, which can cause the airways to become more reactive.
- Increased levels of progesterone and oestrogen may cause airway inflammation and narrowing, leading to increased wheezing, coughing and shortness of breath.
2. Increased respiratory demand:
- As the baby grows, the uterus expands and puts pressure on the diaphragm, reducing lung capacity.
- This can make breathing more difficult, especially for women with asthma, leading to more frequent or severe asthma symptoms.
3. Changes in immune response:
- Pregnancy alters the immune system, which can affect asthma control.
- Some women may find their asthma worsens due to increased sensitivity to allergens or infections.
4. Variation in symptom patterns:
- Asthma symptoms can vary throughout pregnancy. It mostly worsens between weeks 29 and 36.
- Some women may experience improvement in their symptoms, while others may notice a decline in their asthma control, especially in the second and third trimesters.
5. Weight gain:
- Pregnancy often involves weight gain, which can exacerbate asthma symptoms in some women.
- Excess weight can put additional strain on the lungs and airways, making it harder to breathe.
- Maintaining a healthy weight throughout pregnancy can help reduce the risk of asthma flare-ups.
6. Respiratory infections:
- Pregnant women are more susceptible to respiratory infections, such as colds and flu, which can trigger asthma attacks.
- It is important to take preventive measures, such as getting vaccinated against influenza and avoiding exposure to sick individuals.
- Prompt treatment of respiratory infections can help prevent asthma flare-ups.
