More frequent urination is another characteristic of urinary infections. Typically, it is combined with painful urination and discomfort. The inflammation of a bladder causes spasm of the muscles inside the bladder wall (regarding anatomy, the urinary bladder is just a sack made of muscles, lined with epithelial cells on the inside and connective tissue on the outside). Because of the spasm, it’s capacity is greatly reduced and even the smallest amounts of urine trigger the call for urination.
Unlike pathologic intestinal strains of E. Coli, those that cause urinary infections are easier to treat, so after a few days of treatment a patient can return to normal.
