sign of potential sleep apnea problems. Sleepwalking can lead to bedwetting. During sleepwalking, the sleepwalker may think they are in another room. When the sleepwalker urinates during a sleepwalking episode, they usually think they are in the bathroom, and therefore urinate where they think the toilet should be. Cases of this have included opening a closet and urinating in it; urinating on the sofa, and simply urinating in the middle of the room. Stress is a cause of people who return to wetting the bed. Researchers find that moving to a new town, parent conflict or divorce, arrival of a new baby, or loss of a loved one or pet can cause insecurity, contributing to returning bedwetting. Type 1 diabetes mellitus can first present as nocturnal enuresis. It is classically associated with polyuria, polydipsia, and polyphagia; weight loss, lethargy, and diaper candidiasis may also be present in those with new-onset disease. Unconfirmed Food allergies may be part of the cause for some patients. This link is not well established, requiring further research. Improper toilet training is another disputed cause of bedwetting. This theory was more widely supported in the last century and is still cited by some authors today. Some say bedwetting can be caused by improper toilet training, either by starting the training when the child is too young or by being too forceful. Recent research has shown more mixed results and a connection to toilet training has not been proven or disproven. According to the American Academy of Pediatrics, more child abuse occurs during potty training than in any other developmental stage. Dandelions are reputed to be a potent diuretic, and anecdotal reports and folk wisdom say children who handle them can end up wetting the bed. English folk names for the plant are "peebeds" and "pissabeds". In French the dandelion is called pissenlit, which means "piss in bed"; likewise "piscialletto", an Italian folkname, and "meacamas" in Spanish. Mechanism Two physical functions prevent bedwetting. The first is a hormone that reduces urine production at night. The second is the ability to wake up when the bladder is full. Children usually achieve nighttime dryness by developing one or both of these abilities. There appear to be some hereditary factors in how and when these develop. The first ability is a hormone cycle that reduces the body's urine production. At about sunset each day, the body releases a minute burst
