Bed-wetting refers to the involuntary wetting of the bed in the middle of night during childhood. It usually spontaneously stops by the teenage years.
Although the cause(s) of bed-wetting are unknown, chronic bed-wetting is often a general sign that there is some deeper underlying problem. Such problems can include hypoglycemia (low blood sugar), diabetes, and urinary tract infections. Other potential problems are emotional stress, small and weak bladders that cannot hold urine all night, excessive consumption of liquid beverages, sleeping too soundly, food allergies, heredity, and behavioral problems.
Bed-wetting can also be due to food allergies. When allergies are present, the child's bladder can shrink, causing incontinence. Therefore, food allergies must be screened for and treated if found.
