Ask before cutting it.</p><p><strong>Any drink counts.</strong> Water is the one NIDDK names. Sugary drinks work against you, and being overweight raises the risk on its own.</p><p><strong>It is one and done.</strong> Rarely.

If you sweat heavily or live somewhere hot and dry, Mayo lists that as its own risk factor, so you likely need more.</div></details><details><summary>Can I pass a kidney stone at home?</summary><div class="acv-a">Many people do. Cleveland Clinic notes it can take up to three weeks, and small stones can still be extremely painful. Your doctor decides whether waiting is safe based on the size and where it sits.</div></details><details><summary>Should I stop eating spinach and nuts?</summary><div class="acv-a">Only if you had calcium oxalate stones, and only after a conversation. NIDDK lists nuts, peanuts, rhubarb, spinach and wheat bran as high oxalate foods, but the advice is stone type specific.</div></details><details><summary>Does drinking lemon water help?</summary><div class="acv-a">The evidence NIDDK highlights is about total fluid, not any particular flavor. Water is the drink it names. If lemon makes you drink more of it, that is the benefit.</div></details><details><summary>Why do kidney stones hurt so much?</summary><div class="acv-a">The stone blocks urine flow, the kidney swells, and the ureter spasms around it, in Mayo's description. The pain is the spasm, which is why it arrives in waves.</div></details><details><summary>Are kidney stones more common as you get older?</summary><div class="acv-a">Cleveland Clinic puts the peak in men in their thirties and forties, but stones happen at any age. Dehydration, extra body weight and a high sodium diet matter more than the year on your birth certificate.</div></details></div><div class="acv-secondary">Wondering where you stand overall? <a href="/#assessment">Take the free 5-minute Healthspan Snapshot</a> and see your strongest and weakest of six dimensions.</div></div></div>
