A UTI is an infection in the urinary tract. Infections are caused by microbes—organisms too small to be seen without a microscope. Bacteria are the most common cause of UTIs. Normally, bacteria that enter the urinary tract are quickly removed by the body before they cause symptoms. But sometimes bacteria overcome the body’s natural defenses and cause infection.

Finding the right doctor can be a frustrating challenge. Our bodies’ systems are connected in complicated ways. Knowing which specialist is right for which ailment often requires time, research, and expertise.

Physical fitness is defined as “a set of attributes that people have or achieve that relates to the ability to perform physical activity” (USDHHS, 1996). In other words, it is more than being able to run a long distance or lift a lot of weight at the gym. Being fit is not defined only by what kind of activity you do, how long you do it, or at what level of intensity.
