I am 31 years old male, since childhood functional dyspepsia/ bowel disease, can't eat many food , have to follow low FODMAP diet. But due to some important work I had to eat outside food once, then severe diarrhoea and vomiting and then urine production less than 50 ml/ day. Creatinine 8.31 and urea 156, inspite of admitting hospital within 6 hours .Then after admission For 3 days no increase of urine output so 4 times hemodialysis is given and after 21 days creatinine became 0.79 and urea 17.8 . Urine output 1.5 Litre / day. Now my question is ,now my kidney condition is as before getting renal failure??? Or some damaged is there??
