Do you mean that it has become water color? Is there any increase in frequency and amount / volume of urine? Are you on any medications? Any significant past medical or surgical history?
A transparent urine or water color urine is not considered abnormal. So you should not be worried. Since you are taking medications for long, this also may not be related to this. This is called as physiological change and does not denote or point to any disease process. Still a routine urine test can be done to confirm the normalcy. The volume changes are dependent on the fluid consumption and weather changes affect the water intake. In winter months the water consumption gets lessened. The medications, vitamin supplements, herbs, food, and some diseases (like jaundice, stone disease) may give color to the urine, which warrant treatment and investigations.
