There are many reasons for children to urinate frequently after drinking beverages, including water diuresis, osmotic diuresis, and pathologic urinary frequency. Generally speaking, frequent urination after drinking is a normal physiological phenomenon. When the body water increases, it will lead to a decrease in the secretion of antidiuretic hormone, which will lead to an increase in the frequency of urination. And drinks usually contain a lot of sugar or other ingredients, after absorption will produce osmotic diuresis, resulting in frequent urination. The above two cases belong to the physiological frequency of urination, only an increase in the number of times of urination, but each time the amount of urine is normal. At this time, if there is no other physical discomfort can not be treated. But if in addition to increased urination, there is also a change in the amount of urine or urinary pain and other cases, is a pathologic frequency of urination, need to go to the hospital for further examination.
