So I recieved a call from my PCP on Friday evening saying that the labs I had on 4/12 for my 1 month post op were very low in potassium, magnesium and phosphate. She left a v-mail but she was concerned and was urging me to call her office or my surgeoum on Monday. Me, being a nurse and knowing how this can effect the body, called my bariatric coordinator who them contacted my surgeon. After reviewing my labs, he attributed my low labs to low B12 and I have to get a B12 shot on Tuesday. Now my B12 and Iron levels were low before surgery but my surgeon was sure that they would be back to "normal" because of the super vitamins. I have been weak and a lilttle dehydrated since surgery. I'm not disappointed about having to get the shot or even having to get an iron infusion, if needed. I just want to feel better. Long story short, take your vitamins and keep up with your labs. Ask for copies, so you can know if you flucuate. I never new my levels until right before surgery so I know this is not a malabsorbation issue caused by my sleeve.
