Hello all, I'm not sure what is wrong with me and am hoping somebody can shed some light. I have low cholesterol (Total cholesterol = 110, HDL = 35) and frequent thirst / urination at night. I'm going to see a nephrologist in a couple weeks. Is there any correlation to these two things? I have been tested for diabetes. Daytime urination is normal. I pass about 5L of water in a day... 3L at night.
