What is the cause for dark yellow coloured urine and back pain with the history of gallstones when on prenatal vitamins?
Patient: For the past three days I have noticed my urine is a dark yellow and it stains the toilet paper when I wipe. My lower back also has hurt and I have thrown up twic so far. I haven't eaten much because when I do I don't feel well.I have a history of gallstones but have never experienced this before. I also started taking prenatal vitamins two weeks ago because my fiance and I are trying to have a baby. My stool has ranged in color from a tanish light drown to a dull green. Doctor: Hi and welcome to HCM Thanks for the query. it sounds like gallbladder attack and this is the first thing to rule out. your urine color may be changed due to bilirubin elevation which can be seen if your biliary ducts are obstructed by gallstones. vitamins shouldnt be related to your pain. so you need to do ultrasound and check your liver enzymes for start.Wish you good health.
