Hi I am new here.

I am faith,
18 years old and I recently took a blood
test. My cholesterol was high, my BUN TEST
was 22. Which was high. My BUN/Creatinine
Ratio was 28 which was high. Although my
creatinine was normal. My potassium level
was 5.5. which was high. Also my urine
test came out abnormal showing i might
have A uti on top of that. My doctor wants
me to do my blood test and my urine test
over. Lately i have been feeling tired

, and
i dont drink enough fluids. My stomach
sometimes hurts, can this be signs of
kidney failure??? I need answers.
