It is normal for small children to pass urine in bed during sleep. However in some children this tendency persists even after the age of 5 years. If it occurs at least twice a week for 3 months, then it is considered to be a disease and is called bedwetting or enuresis. Bedwetting is the most frequently seen paediatric problem and is called shayyamutrata in Ayurveda.
Various causative factors responsible for bedwetting include small capacity of urinary bladder, weak bladder muscles, neurological problems, intestinal worms, psychological factors (like fear, anger etc) and maturation delay. Habit of drinking excessive water and genetic factors too are sometimes responsible for bedwetting.
Shayyamutrata is considered to be a vata disorder in Ayurveda as elimination of urine happens to be the function of vata. Ayurveda offers effective treatments for this problem that affects hundreds of children across the world.
