When there is kidney damage or kidney disease, and the kidneys are not able to filter waste efficiently, there will likely be a rise in creatinine levels in the blood. For adults with kidney disease, dialysis is recommended when creatinine levels reach 10.0 mg/dL.
The two types of gallstones are cholesterol stones and pigment stones. Cholesterol stones are usually yellow-green and are made primarily of hardened cholesterol. They account for about 80 percent of gallstones. Pigment stones are small, dark stones made of bilirubin.
Gallstones are like tiny rocks that form in the gallbladder. They are made of cholesterol or bile particles that clump into a solid mass. A stone can grow as liver bile passes through the gallbladder. Most gallstones are small enough to pass out of the body through the intestines without our noticing.
