The vast majority of uremic patients have combined hypertension, which is mainly caused by water and sodium retention. Hypertension can damage the heart and blood vessels, so most uremic patients have ventricular hypertrophy and dilated cardiomyopathy. Therefore, daily blood pressure measurement is necessary to keep the blood pressure in a reasonable range in a timely manner, which can reduce the burden on the heart. Body temperature should be taken every day because bacterial infection can lead to aggravation of heart failure, and timely intervention is required to detect elevated body temperature. Patients with uremia have greatly reduced physical fitness and have difficulty moving around, so they are instructed not to maintain a posture that could lead to decubitus ulcers from local compression, and to control water intake if lower limb edema is severe, otherwise it could lead to further aggravation of edema and increase the burden on the heart. The first symptom of uremia is indigestion, so usually a light diet is required to avoid aggravating the burden on the spleen and stomach.
