πͺ¨ A. Elevated acid levels (uric acid) β MODIFIABLE
πHyperuricosuria and low urine pH promote uric acid stones and can nucleate calcium oxalate stones.
πManagement: reduce purine-rich foods (organ meats, certain fish), increase citrate (alkalinizes urine), and consider potassium citrate or allopurinol if indicated.
πAim for urine pH ~6β6.5 for uric-acid stone prevention.
πWeight control and insulin sensitivity also help normalize acid-base balance in urine.
πͺ¨ C. Diet high in animal protein β MODIFIABLE
πHigh animal protein increases uric acid, calciuria, and reduces citrate (a natural stone inhibitor), raising risk for uric acid and calcium oxalate stones.
πCounsel on moderation of animal protein, more plant proteins, and balanced meals with calcium + oxalate timing.
πExcess sodium (often paired with protein diets) further increases urinary calciumβlimit sodium to <2 g/day when possible.
πEmphasize portion control rather than total elimination.
πͺ¨ D. Frequent UTIs β MODIFIABLE
πRecurrent infections with urease-producing bacteria (e.g., Proteus, Klebsiella) create alkaline urine and struvite (magnesium ammonium phosphate) stones.
πStrategy: prompt diagnosis and treatment, consider urology for source control, and ensure complete stone removal to stop the infection-stone cycle.
πHydration and voiding habits support prevention; sometimes prophylaxis is considered.
πEducate on recognizing early UTI symptoms and completing antibiotics.
πͺ¨ E. Excessive intake of calcium-based antacids β MODIFIABLE
πHigh-dose calcium carbonate supplements/antacids can increase urinary calcium, predisposing to calcium stones.
πNuance: Adequate dietary calcium (with meals) helps bind oxalate in the gut and reduce stone risk, but excess supplemental calcium is problematic.
πPrefer dietary calcium over large, frequent supplements; if supplements are needed, take with meals and under guidance.
πAvoid indiscriminate antacid use; review for GERD alternatives or other therapies.
πͺ¨ F. Inadequate fluid intake β MODIFIABLE (strongest factor)
πLow urine volume leads to supersaturation of stone-forming salts.
πTarget urine output > 2β2.5 L/day (usually needs ~2.5β3 L fluid/day, more with heat/exertion).
πInclude citrate-containing beverages (e.g., lemon/lime) to increase urinary citrate; limit sugary sodas (especially colas with phosphoric acid).
πTeach distributed intake throughout the day and extra fluids with exercise or hot weather.
