Kidney stones vs Gallstones
- Ashtvinatak Hospital
- October 1, 2026
Both involve hard deposits forming somewhere they shouldn’t, but that’s really where the similarities end. Kidney stones form when minerals and salts in the urine crystallize inside the kidneys. Gallstones, on the other hand, develop in the gallbladder when cholesterol or bilirubin hardens over time. The pain from each shows up in noticeably different places kidney stone pain tends to start in the back or side, then travel down toward the lower abdomen or groin, while gallstone pain sits in the upper right abdomen and can radiate up toward the shoulder or back. Both can hurt like nothing else, honestly. Getting an accurate diagnosis through imaging and lab work matters a lot here, since treatment hinges on the stone’s type, size, and exact location. Catching it early really does make recovery smoother and helps avoid complications down the road.
