OK, I was in the hospital for 24 hour observation after a car accident and they ran blood tests on me and found out I've got a potassium deficiency. I'm not looking into what foods are excellent sources of potassium besides bananas - I'm allergic to them - but I'm kind of at a loss here. A lot of the foods listed on one site are items that I eat regularly. How on earth can I have a potassium deficiency then? Is this a common occurrance in pregnancy and what effects might this have on me and the baby???
