Low Potassium and Magneisum

Cynthia Flynn's picture


Dear Midwife,
My daughter is almost 6 months pregnant and her blood tests show she is low 3.2 versus 3.5 in her potassium levels. They tried to get her count to the normal rate using an IV and nothing changed after 6 bags. They have her taking several potassium pills a day and it only went from 3.1 to 3.2 after 2 weeks. They are now sending her to a renal doctor (kidneys) but they say the baby is fine.

I have tried to research this on the web without much luck. Should we be concerned? One OB doctor said it wasn't a great concern that it is sometimes normal in young women and should improve after the baby is born, the other one says she is not too concerned but wants us to go see a specialist anyway? She is having no symptoms or problems.


I'm sorry, I have never heard of such a problem that couldn't be solved, so I would defer to the specialist.

I suffer from low potassium while pregnant. I'm going through it in fact a fourth time. My OB doctors, kidney doctors, heart doctors, no one had an answer for me. My potassium gets really really low in 3rd trimester and I have to take alot of supplements daily. They can't keep it in me. But after the birth of my babies it goes back to normal.

Tell your daughter feeling extremely weak like her body is much heavier and she can barley stand on her feet, muscle soreness, etc is not normal and a serious sign potassium is low and she needs it or it can be fatal. I found an article though that mentions a cause for this in two other ladies while pregnant was because they drink to much soda. I too drink to much soda, so now I'm thinking that just maybe this is the answer.
