You know what the most common question that I get asked by new Mum’s after birth is?
HINT: It’s not ‘why doesn’t this thing come with instructions?!’
It’s about the sudden increase in fluid women commonly notice after birth, particularly in their feet and lower legs.
The common assumption is that this fluid must be sinister, and possibly reflect a disease process like pre-eclampsia - but it is typically just a normal physiological response to the changes in the uterus after birth.
About 500 mos of blood is pretty rapidly expelled from the uterine muscle after birth when it contracts, with the blood being dumped into the circulatory system.
The body then realises it needs to adjust this, and it dumps fluid out of the blood which then accumulates initially in the peripheral tissue until the body is able to clear it over the subsequent weeks.
So certainly ask if you’re concerned - but it is usually all good!
