The kidneys maintain the blood creatinine in a normal range. Creatinine has been found to be a fairly reliable indicator of kidney function. Elevated creatinine level signifies impaired kidney function or kidney disease.
If you feel nauseated, here are some tips: 1  Avoid foods that are hard to digest. 2  If the smell of hot food makes you feel ill, try eating cool or cold meals. 3  Eat six small meals each day instead of three large ones. 4  Do not lay down after eating. 5  Rest with your head higher than your feet.
The best foods to eat while feeling nausea are clear liquids that can keep your system hydrated. You can also intake fluids like chipped ice, Gatorade, ginger ale, clear broths, gelatin and ice pops. Start with about 4 to 6 ounces at a time. Sometimes warm decaffeinated tea with honey may help to coat the throat and soothe it. You can also try bland foods called BRAT foods (banana, rice, applesauce, toast).
