Commonly, kidney stones are the first sign of hyperoxaluria. Kidney stones are uncommon in childhood. Kidney stones that form in children and teenagers are likely to be caused by an underlying condition, such as hyperoxaluria. For this reason, all young people with kidney stones should have a thorough evaluation, including measurement of oxalate in the urine. Adults with recurrent kidney stones also should be evaluated for oxalate in the urine.
Symptoms of a kidney stone can include the following:
- Severe or sudden abdominal or flank pain
- Blood in the urine
- Frequent urge to urinate
- Pain when urinating
- Fever and chills
- Primary hyperoxaluria (PH) that goes untreated can eventually damage your kidneys. Over time your kidneys may stop working. For some people, this is the first sign of the disease.
Symptoms of kidney failure can include the following:
- Decrease in urine output or no urine output at all
- Feeling generally ill, tired or heavy fatigue
- Loss of appetite, nausea and vomiting
- Pale skin color related to anemia
Oxalosis in its late stages can cause a variety of complications outside the kidney, including bone disease, anemia, skin ulcers, heart and eye problems, and in children, a failure to develop and grow normally.
