I am four days post-op and find that my urine is a very deep yellow. I've been on liquids only. why is this?

Did you start taking vitamins? That will do it.

Moon is right about the vitamins. Also, if you aren't drinking a lot of H20/aqua/water...that can happen as well. Try drinking more water, room temp, start first thing in the morning, no straw, sip, and keep your water with you all day. You may find that deep color will change if not, call the doc.

You are not drinking enough liquids. You have to drink at least 64 ounces of liquid. Especially to get rid of the fat and waste that your body will produce while loosing the pounds! Drink Drink Drink

Same thing happened to me, and lordy - did it ever whiff!

It was definitely due to not drinking enough Water and everything got back to normal once I was back to my normal couple of bottles a day.

We were told that if your urine is dark it is a sign of dehydration and that more water was needed.
