Urinary Disorders

My urine is colorless, why? 1 kidney



I lost one kidney to cancer 5 years ago, and I started taking Lyrica a month ago. Now my urine is totally colorless. I had a B12 shot this week, and my urine was pink for one night.

Is colorless urine a bad symptom? Thank you.


The color of your urine may reflect how hydrated you are. Colorless urine is not a bad symptom and means that you are well hydrated. When you see pink or red however, you should see your doctor and have the urine checked to see if this represents blood in which case further evaluation may be indicated.
