12/27/2023 0 Comments Secondary enuresisSeveral studies have found a high incidence of detrusor instability (OAB) with nocturnal enuresis. Some people have an ‘overactive’ or ‘unstable’ bladder (OAB) which causes problems at night as well as during the day. The overactivity of the detrusor muscle (bladder) indicates that the muscle is never fully relaxed during the filling phase and therefore the bladder capacity is not as large. The FBC is the amount of urine the bladder holds before sending a signal to the brain to indicate the need to void. This does not mean that the actual size of the bladder is smaller in nocturnal enuresis patients, rather that their functional bladder capacity (FBC) is a smaller volume. When one parent wet the bed as a child, then their child was found to have a 40% chance of becoming a bedwetter.Īnother cause put forward for primary nocturnal enuresis is a smaller than average bladder. One study showed that someone with two bedwetting parents has a 77% chance of also becoming a bedwetter. Though this is not true for everyone, evidence has shown that bedwetting is hereditary. Research has shown that nocturnal enuresis can occur due to a genetic link. So why don’t you wake up when you need to go to the toilet? Unfortunately, there is no clear cut answer to this question. However, some people produce larger amounts of urine during the night, which may explain why the bladder needs emptying then. Usually people produce less urine when they are sleeping. There are many causes of bedwetting and others remain unclear. What Causes Bedwetting (Nocturnal Enuresis)? Dryness may have occurred for many years but then night time wetting suddenly begins at an older age. Adult Onset Secondary Enuresis is defined as nocturnal enuresis in which night time dryness has been achieved at some point in life. About 2 – 3% of adults over 18 years of age have this type of nocturnal enuresis. Persistent Primary Nocturnal Enuresis is a condition which starts during childhood, where night time dryness has not been achieved for longer than six months. Bed wetting can affect sleep patterns and often it causes frustration and exhaustion.īedwetting can also affect self-esteem which can put a strain on personal relationships. Bed wetting can affect staying away overnight, going on holiday or business trips. Bed wetting causes many practical problems, such as constantly having to change wet sheets and bedding.
