Although there may be different medical conditions that can lead to an elevated creatinine blood level, a main cause may be kidney dysfunction with additional symptoms being dehydration, edema, feeling tired and breathing problems, as noted by MedicineNet. In many cases, a patient with an elevated creatinine blood level count may not present any symptoms.
The creatinine test is normally ordered by a doctor to check kidney function in a patient. Creatinine is a waste product excreted by the kidneys. When the kidneys are not working properly, creatinine levels can be either abnormally high or low. The normal range of creatinine blood levels in men is 0.6 to 1.3 mg/dL, as noted by Mayo Clinic. However, this range may vary due to factors, such as gender and age.
Increased levels of creatinine can be related to conditions, such as urinary tract obstructions, complications of pregnancy, muscle disorders, dehydration and different types of kidney problems. Additionally, some underlying conditions that can lead to kidney dysfunction are diabetes, hypertension and a kidney infection, states MedicineNet. Some other causes of a high creatinine level are eating high amounts of meat, taking a creatine supplement and certain medications.
Because there are so many medical conditions or underlying causes for an elevated creatinine blood level, there may be other accompanying symptoms than the ones cited for kidney dysfunction. For example, hypertension that leads to kidney disease, can have symptoms that include loss of weight or appetite, nausea, muscle cramps, edema in lower extremities, urination problems, itchy skin and headaches. However, these symptoms tend to manifest in later stages when kidney function begins to decrease, states the National Institute of Diabetes and Digestive and Kidney Diseases.
