Renal Stone
Causes, Etiology, and Diet
Causes and Etiology
1. Dehydration: Insufficient fluid intake can concentrate minerals in the urine, increasing the risk of stone formation.
2. Diet: Consuming foods high in oxalate, sodium, and animal protein can increase the risk.
3. Family history: Genetic predisposition can play a role.
4. Medical conditions: Conditions like hyperparathyroidism, gout, and certain genetic disorders can increase the risk.
5. Medications: Certain medications, such as diuretics and antacids, can increase the risk.
Types of Renal Stones
1. Calcium oxalate stones: Most common type, often caused by excess oxalate in the urine.
2. Uric acid stones: More common in people with gout or those who consume a high-purine diet.
3. Struvite stones: Typically caused by urinary tract infections (UTIs).
4. Cystine stones: Rare, genetic disorder causing cystine buildup in the urine.
