If a child frequently wets themselves, it could be due to a relaxed bladder sphincter. In traditional Chinese medicine, this condition is categorized into kidney Qi deficiency, spleen and lung Qi deficiency, liver meridian damp-heat, and heart-kidney disharmony.
Frequent urination in children can be physiological or pathological, caused by factors such as excessive drinking, cold weather, or stress. If accompanied by other symptoms like abnormal bowel movements or unexplained weight loss, it may be due to certain diseases. These can include urogenital issues such as cystitis, urethritis, or other related conditions like diabetes or diabetes insipidus. To determine the cause of frequent urination, it is recommended to undergo urine routine tests, bilateral kidney ultrasound, and blood sugar tests. These checks usually help to rule out or confirm potential diseases and provide appropriate treatment advice. Therefore, I suggest taking your child to the hospital for a detailed examination to receive an accurate diagnosis and treatment.
