symptoms of high creatinine

Creatinine is a waste product in your body.Creatinine is a chemical waste product in the blood that passes through the kidneys to be filtered and eliminated in urine.Normally, your kidneys filter creatinine out of your bloodstream.Creatinine is made from creatine, a supplier of energy to the muscle.When muscles work, they break down proteins, including the amino acid creatine, to produce energy.Generally creatinine levels in the blood remain unchanged from day to day because muscle mass usually stays the same.Levels of creatinine can be affected by age, sex, race, diet, muscle mass, some medications, and chronic disease, such as hyperthyroidism, hypothyroidism, diabetes and kidney disease.

Symptoms associated with high creatinine are most often caused by an underlying illness that affects kidney function.The most frequent cause is kidney disease itself.feel more tired and have less energy;have trouble concentrating;have trouble sleeping;have muscle cramping at night;have puffiness around your eyes, especially in the morning;need to urinate more often, especially at night.have dry, itchy skin;have swollen feet and ankles;have a poor appetite;Other symptoms may indicate muscle destruction, hypothyroidism, or diabetic ketoacidosis as the cause of elevated creatinine.A high creatinine level does not necessarily mean the person has chronic kidney disease, but indicates the need for other tests.
