Hello and welcome to HCM. Your concern is understandable. As an Urologist, let me advise you, that with CKD(Chronic Kidney Disease), you re prone to electrolyte (salt and potassium), changes with diarrhoea. The kidney function tests, like blood creatinine, and urea with electrolytes need to be checked, and corrected according to changes seen. An Ultrasound scan of the abdomen may be advised, if needed.You may need admission after an examination. You should be careful to avoid potassium rich diets,like fresh fruits,coconut water, and adding table salt.Take fluid intake slightly more than urine output.You may contact me by name, with reports ,for expert opinion.
