Uncontrolled asthma during pregnancy reduces maternal blood oxygen levels, directly affecting the baby through the placenta. The risks include premature birth, low birth weight, restricted foetal growth, pre-eclampsia, and in severe cases, pregnancy loss. This is why Dr. Dixit Kumar Thakur at Pulmovista Clinics emphasises that well-managed asthma with appropriate medication is significantly safer than uncontrolled asthma without it.
