The phenomenon of frequent urination is called frequent urination. Normal people usually urinate less than seven times a day, but if the number of times is more than seven, it is considered frequent urination. Frequent urination is often caused by some diseases or stressful situations, such as cold stimulation or excessive stress, which can cause an increase in the number of urination, which is physiological. In addition, some pathological factors, such as the presence of urinary tract infections, urinary tract tuberculosis, ureteral end stones, etc., can cause an increase in the number of urination, mainly due to sensory allergies in the bladder mucosa, or due to various reasons such as bladder irritation, making the number of urination significantly higher than normal.
