2) Fever
Similar to any other infection in the organism, fever is one of the most important symptoms to detect kidney infections. However, it is often a late symptom instead of an early warning sign. Fever appears in a late stage of the disease, only when the infection is sustained and progresses without restraint. It is one of the immune responses to protect the organism against pathogens or microbial invaders. Increasing body temperature is another way the body has to destroy bacteria, and this effect is triggered by the inflammatory mediators released to the bloodstream.
In this regard, we should note the difference between a kidney infection in infants and adults. Different from adults, infants would have fever as one of the most predominant symptoms, and it is often the only one. In many cases, fever with unknown origin in an infant is caused by a kidney infection, and your pediatrician would need to perform a physical exam and diagnostic tests to figure out the difference.
Fever usually stops as the antibiotic therapy is initiated, and it is usually a mild fever but sometimes would reach 40°C and more. Since fever is a common symptom in many infectious diseases, it is important to figure out the real cause before starting medications. Thus, do not neglect your condition, do not self-medicate, and go to your doctor to get a proper assessment of your health condition.
