5. Changes in the physical characteristics of urine
Many patients go to the doctor because they notice changes in their urine, for example, the urine may become purulent (it becomes cloudy, thicker, and loses its transparency), red, bright pink or cola-colored (due to the presence of blood in it), and adopts a stronger and unpleasant smell.
The following are among the most common non-specific symptoms of a urinary tract infection, in both children and elder people:
This symptom can range from a hot flush to the development of high fever (which indicates a more severe infection). In some cases the hot flush only produces redness of the skin (especially the cheeks), which is quite unspecific.
However, it is very nonspecific because many infections (including viral, bacterial and some parasitic infections) can cause fever. The body’s temperature elevation is due to the bacterial stimulation of the body’s immune system to fight the infection.
