Wireless bedwetting alarm: what you should know

The sensor is placed in underwear or bedding according to its instructions. When it detects urine, it triggers a sound, vibration or light through a separate receiver. The aim is to help the sleeper wake, turn off the alarm, go to the toilet and reset the equipment. Wireless designs can allow the alert unit to be placed away from the bed.

Bedwetting is common in children and can also occur in adults. It is not a child's fault and punishment can add distress. An alarm is a training tool, so calm, consistent support matters more than reacting to an occasional wet night.

Read the device instructions before the first night and practise the response while everyone is awake. Make sure the person using it can reach the toilet safely, with a clear route and a night light if needed. A parent or carer may need to help a deep sleeper wake at first. Clean and dry the sensor as directed, and keep a simple diary of wet nights, dry nights and alarms.

Avoid shaming, rushing or taking away drinks indiscriminately. A clinician can advise on daytime drinking and toileting habits that suit the person's age and health.

Arrange a review for new bedwetting after a period of dryness, daytime wetting, pain or burning when passing urine, constipation, excessive thirst, marked tiredness or loud snoring with breathing pauses. Seek urgent medical care if a person is very unwell, confused, vomiting repeatedly, or has severe abdominal pain.

Ask whether an alarm is appropriate now, how to respond when it sounds, and what progress signs to record. Mention urinary symptoms, bowel habits, sleep quality, thirst, medicines, family history and any emotional strain around bedwetting.
