I have been on keto diet and have noticed bubbles
Bubbles in urine are mostly due to urine being concentrated
Thanks for query
Based on the facts that you have been on Keto Diet and have noticed bubbles in your urine since very recently .
The bubbles in urine are mostly due to urine being concentrated resulting out of reduced water and carbohydrate intake and excessive loss of water from the body along with metabolism of carbohydrates stored in liver .
It is not due to Keto Diet per SE
Get your routine urine test done to rule out infection and to know the specific gravity of urine in particular.
Ensure to drink more water to keep yourself well hydrated.
Hope I have answered your query ,please feel free to ask if you have more questions,I shall be happy to help you
Thanks and Regards.
