Kidney stones are made up of calcium, uric acid, oxalate, or cystine. Stones develop when you have high levels of these substances in your urine. They can also form when levels are normal but you’re not producing sufficient amounts of urine each day.
When these substances crystallize in your kidneys, they can grow larger over time and form a stone. The stone typically moves through your urinary tract and leaves your body when you urinate.
Larger stones may be more difficult to pass and can block your urinary tract, interfering with your ability to urinate. If stones are too large to pass, it may be recommended that they are removed this usually involves the involvement of another specialist called a Urologist.
Anyone can get a kidney stone, but risk factors include:
- History or kidney stones
- Family history of kidney stones
- High protein, sodium/salt, and or sugar diet
- People who do not drink enough water
- Taking certain medications such as diuretics/water pills or calcium based antacids
- Overweight or obese
- Gastric bypass surgery or other intestinal surgery
- PKD or cystic kidney disease
Conditions that cause your urine to contain high levels of cystine, oxalate, uric acid or calcium.
