Foamy Urine

I had foamy urine because of protein in my urine 3 years ago. My Doctor sent me to a Kidney specialist who after 5 visits said the protein was gone. I also had an ultra sound of my kidneys which came back negative. I have medication for high blood pressure but when I lose excess weight I have to be taken off the medication. My creatinine levels were also normal when test. My latest test said protein in the urine. I am terrible about drinking water and noticed my mouth have been dry several times this week. I'm wondering is dehydration

Mine is always abit foamy bubbles I thought that was normal. I have stage 3 a ckd gfr 52.

Have you changed your diet?

Well I vary my diet a lot 

I try to adopt a plant based life style

It definately could be dehydration.  But be careful because dehydration can also cause problems for your kidneys.  Drink plenty of water.
