Early symptoms of elevated blood creatinine show mild discomfort such as fatigue, back pain, increased nighttime urination, and loss of appetite.
Gastrointestinal Symptoms Digestive symptoms are usually the earliest manifestation of elevated blood creatinine. The main manifestations include lack of appetite, nausea, vomiting, and the taste of urine in the mouth. Gastrointestinal bleeding is also more common, with a significantly higher incidence than normal, mostly due to gastric mucosal erosion or peptic ulcer. At the same time, patients are often accompanied by symptoms of fatigue, insomnia, poor concentration, lumbago, and increased nocturia.
As the disease progresses, the above symptoms become more obvious. In the uremia stage, acute left heart failure, severe hyperkalemia, gastrointestinal bleeding, central nervous system disorders and so on can occur, and even life-threatening.
Patients with elevated blood creatinine are recommended to consult regular hospitals and receive standardized treatment under the guidance of physicians.
