Does the flu affect a breast-feeding woman more severely? I have fatigue after the flu.

Yes, this is possible and there are two reasons why it might be so:

•    Pregnancy suppresses your immune system. If your child has been born only recently, your immune system might not have recovered to its full strength

•    Alternatively, breast-feeding requires lots of nutrients and sometimes, your body may become deficient in vitamins, minerals, proteins etc. This can also affect your immune response.

I hope that this information is helpful to you.
