Ugh, seriously? As if dealing with periods wasn’t hard enough already. Bloating, mood swings, fatigue, increased appetite, EVERYTHING – you can just tell when it’s that time of the month again.
There are so many symptoms of PMS (premenstrual syndrome) that can range from mildly annoying to 100% overwhelming. But something you might not have thought about is that your immune system actually gets weaker during your period.
Yes. So when you find yourself catching a cold or just feeling under the weather during your period, it’s because of your immune system.

When Should You See A Doctor?
- If you often catch colds or get sick before or during your period, please see a doctor. They will help figure out what it is.
- If your periods pains are severe, you’re always having a heavy bleeding, or mental health issues, talk to a doctor about it. PMS is common, but it shouldn’t control your life every month.
What’s The Deal Between Your Period And Your Immune System?
Hormone changes, especially with estrogen and progesterone, during your menstrual cycle can mess with your immune system. Progesterone, in particular, can weaken your body’s ability to fight off infections. So, when progesterone levels spike after ovulation (to get your uterus ready for a fertilized egg), you are more likely to catch something.
Estrogen spikes right before ovulation, it boosts the production of histamine – the chemical that triggers allergic reactions. This can cause symptoms similar to allergies or a mild flu, like nausea, dizziness, feeling generally unwell, and overall fatigue. This is what we call a “period flu” during menstruation.
Now, not everyone will get sick during their period; some women have stronger immune systems than others. But if you find yourself getting sick every time your period is about to start, see a doctor.
