Causes of Frequent Urination in Children

It may be frustrating when your previously toilet-trained child starts having frequent urination and urinary accidents. Frequent urination in children can result in incontinence during the day or overnight, and may cause embarrassment and social withdrawal in your child. According to the Mayo Clinic and the National Center for Diabetes, Digestive and Kidney Diseases, causes of frequent urination in children include lifestyle factors and bladder disorders.

Slow Development

• Development of a child's ability to hold urine in may occur slowly and can result in frequent urination, especially at night while she is sleeping.

Capacity

• Children have smaller bladder capacity than adults do and are not able to hold as much urine for as long as an adult can.

Emotions

• If your child is experiencing emotional stress or anxiety, frequent urination and urinary accidents can occur, which and can result in even more anxiety.

Habits

• Drinking a large amount of water, juice or caffeinated soda can cause your child to produce an excessive amount of urine, especially at nighttime.

Infections

• Frequent urination may be caused by bladder or urinary tract infections. These types of infections are more common in girls due to spreading of vaginal bacteria to the urinary system.

Bladder Disorders

• Structural problems of the bladder, kidneys or urinary tract, as well as bladder irritations caused by allergic reactions to foods or medications, may cause frequent urination in children.
