Quick Answer: Pregnancy naturally modifies immune function to help the body tolerate the developing baby, which can leave some people feeling more susceptible to minor illnesses. This is a normal adaptation, not a sign something is wrong — though it's worth taking extra care with hygiene and nutrition.

Why Immune Function Shifts During Pregnancy
During pregnancy, the immune system undergoes a natural, complex adjustment. Part of the developing baby's genetic material comes from the other biological parent, so the immune system adapts to avoid rejecting it — while still needing to protect both parent and baby from infection. This balancing act is a normal, expected part of pregnancy physiology.
Common Changes You Might Notice
- Feeling more run down or catching minor colds more easily
- Changes in how quickly symptoms resolve
- Increased general fatigue, which can compound how illness feels
These changes are considered a normal part of pregnancy for most people, though any concerning or persistent symptoms should always be discussed with your midwife or doctor.
Supporting Your Immune Health Safely
- Prioritise sleep — easier said than done in later trimesters, but rest remains foundational.
- Eat a varied, nutrient-dense diet — pregnancy increases the demand for several key nutrients.
- Stay up to date with recommended vaccinations — your doctor or midwife can advise which are recommended during pregnancy.
- Practise good hand hygiene — a simple, safe habit throughout pregnancy.
