Enuresis is the medical to describe what is commonly known as bedwetting term. It is quite common during childhood, and is more common in boys than in girls. Bedwetting is not caused by taking too much fluid before bedtime, or by a mental or behavioral problem, but has other causes: genetic factors, difficulty waking, urinary tract infections and slow development of the central nervous system , among others. Childhood nocturnal enuresis can occur because the child's bladder is too small; also because the amount of urine produced at night is greater than your bladder you can hold, or simply because they need more time to learn to control this body. As for treatment, usually drugs that help the bladder hold more urine only when the previous behavior therapy has not worked is used.
