Understanding Nocturnal Enuresis or Night (Bed) Wetting and the Role of ADH

Why do children still wet the bed after they are completely potty trained during the daytime?

If you're reading this, chances are you've encountered the frustrating challenge of bedwetting, also known as nocturnal enuresis, with your child. It can be even more frustrating when your child has been completely potty trained during the daytime for several months and never has accidents. You're not alone in this journey, and there are plenty of strategies available to help your child overcome this common issue. This post explores everything you need to know about bedwetting and how ADH (antidiuretic hormone) plays a crucial role in the process of potty training.

Understanding Bedwetting: Bedwetting is a common occurrence among children, particularly during their early years of development. It refers to the involuntary release of urine during sleep, typically at night. While it can be a source of embarrassment and frustration for both children and parents alike, it's essential to recognize that bedwetting is a natural part of growing up for many kids.

What are the causes of bed wetting or nocturnal enuresis in children?

Several factors can contribute to bedwetting in children, including developmental delays, genetics, hormonal imbalance, stress or anxiety, and underlying medical conditions such as urinary tract infections or sleep apnea.

What is (ADH) anti-diuretic hormone also known as vasopressin?

Role of ADH in Bedwetting: ADH, also known as vasopressin, is a hormone produced by the hypothalamus and released by the pituitary gland. Its primary role is to regulate the body's water balance and urine concentration by controlling the amount of water reabsorbed by the kidneys. When the body detects low water levels or high concentrations of dissolved substances in the blood, ADH is released to enhance water reabsorption and conserve water.

What is the role of ADH in potty training?

During the potty training process, children gradually learn to recognize the sensations associated with a full bladder and gain control over their urinary sphincter muscles to voluntarily hold urine until they reach a toilet. The ability to control urination involves a complex interplay between neurological development, muscular coordination, and hormonal regulation, including the influence of ADH.

In infants and young children, variations in ADH secretion and responsiveness may influence urinary patterns and bladder control. Some children may produce insufficient levels of ADH during sleep, leading to increased urine production and bedwetting (nocturnal enuresis). Conversely, others may have difficulty responding to the signals of a full bladder due to delayed neurological development or decreased sensitivity to ADH.

As children grow and their hormonal and neurological systems mature, they typically gain better control over bladder function and become more proficient in recognizing and responding to the urge to urinate. However, individual differences in ADH secretion and responsiveness may influence the timing and success of potty training.

Children usually are able to stay dry at night 10 months after they are daytime potty trained.

As a general guideline, it's commonly observed that around 10 months after children successfully complete daytime potty training, they also become nighttime trained, meaning they can stay dry through the night. This transition is closely linked to the body's ability to produce adequate levels of ADH (antidiuretic hormone), which plays a crucial role in regulating urine production during sleep.

Before children can stay dry at night, their bodies need to develop the capability to secrete sufficient ADH. Without enough ADH, their bodies are unable to effectively regulate and suppress urine production during sleep. Once children start producing enough ADH to manage urine production during the daytime, it typically takes about 10 more months for their bodies to reach the point where they can produce higher levels of ADH needed to slow down urine production at night.


Bedwetting  adds another dimension to the potty training challenge for children and parents alike, but with patience, understanding, and proactive strategies, it's a hurdle that can be overcome. ADH plays a crucial role in regulating water balance, urine concentration, and bladder function, providing insights into the physiological factors that contribute to urinary control and helping parents navigate the challenges of toilet training with patience and knowledge. Remember, every child is unique, and with the right support and guidance, they can conquer bedwetting and achieve success in potty training. You've got this!
