Dehydration: It appears that you may have dehyrdated cauisng hypernatremic (hypertonic) dehydration. This occurs when the lost fluid contains less sodium than the blood (loss of hypotonic fluid).

Proteinuria: You have proteinuria (p) and the first thing is to have a 24 hour urine collection to see the amount of protein in your urine and to assess your kidney function. Have a renal ultrasound to assess kidneys' size depending on the p, i would send off blood for aso, anca 2, complement c3 and c4, hiv, hepatitis b antibody to see if a cause could be found for the p, if not a kidney biopsy may be needed. ...Read more

Protein in urine: The results mean that you probably have a lot of protein in your urine. To determine how much, you need to see a nephrologist and have a 24 hour urine collection to assess the amount of protein in your urine as well as your renal function. Depending on the amount of protein in your urine, you may need to have additional blood tests to see if you have any type of glomeulonephritis or diabetes. ...Read more
