10 Kidney Infection Symptoms
Symptom #5: Lethargy
Another non-specific symptom that can be seen in patients with pyelonephritis; lethargy, weakness, fatigue, or tiredness can affect patients to the point where they fall asleep most of the day despite having adequate sleep throughout the night. This occurs as the body is burning many calories fighting off the infection. Rest is also a great way to help boost your immune system to fight against infections.
In a kidney infection that has been there for a while, it may affect the function of the kidneys to produce erythropoietin which is a hormone that signals the bone marrow to produce more red blood cells. When there is a lowered rate of erythropoietin, there is decreased production of red blood cells which leads to a lowered function of oxygen supply. This causes the affected individual to feel tired and cold.
