Congenital Adrenal Hyperplasia (CAH) is a genetic disorder that may not be widely known but can have serious, lifelong consequences if left undiagnosed or untreated. Affecting the adrenal glands, which are responsible for producing key hormones like cortisol and aldosterone, CAH disrupts the body’s ability to maintain balance in stress response, metabolism, and salt regulation.
As a parent, it’s essential to understand the hidden dangers of CAH and recognize whether your child could be at risk. This article will uncover the causes, symptoms, and treatment options, helping you stay informed and prepared.
What is Congenital Adrenal Hyperplasia?
CAH refers to a group of inherited disorders that cause a deficiency in certain enzymes required for hormone production. The most common type involves a deficiency in the enzyme 21-hydroxylase, which disrupts the production of cortisol and aldosterone while leading to an overproduction of androgens, or male sex hormones.
When hormone production is thrown off balance, it can lead to a host of health complications. In severe cases, CAH can result in life-threatening symptoms, making early detection and treatment crucial.

Could Your Child Be at Risk?
CAH is inherited in an autosomal recessive pattern, meaning a child must inherit two copies of the defective gene—one from each parent—to have the disorder. Even if both parents are carriers, there is only a 25 percent chance that their child will inherit the condition. However, if both parents carry the gene, the risk is real.
In many cases, newborn screening tests can identify CAH early, but symptoms may also appear later in life. This makes it important for parents to be aware of key warning signs.
Hidden Symptoms: What to Look For
CAH can manifest in various ways depending on its severity. The disorder is divided into two main types: classic CAH and non-classic CAH, each with distinct symptoms.
1. Classic CAH (Severe Form)
Classic CAH is the more dangerous form of the disorder, often presenting shortly after birth or during early childhood. It includes two subtypes: salt-wasting CAH and simple virilizing CAH.

- Salt-Wasting CAH: This is the most severe form and can be life-threatening. It impairs the body’s ability to retain salt and water, leading to dehydration, vomiting, low blood pressure, and shock in infants. Early intervention is critical, as undiagnosed salt-wasting CAH can be fatal within weeks of birth.
- Simple Virilizing CAH: Although it doesn’t involve the salt-wasting symptoms, this type leads to early puberty in both boys and girls. Boys may develop a deep voice and facial hair prematurely, while girls may be born with ambiguous genitalia. This can cause significant distress if left untreated.
2. Non-Classic CAH (Mild Form)
Non-classic CAH is less severe and often doesn’t present symptoms until adolescence or adulthood. This form may not be detected in newborn screenings, so parents should be aware of signs that could arise later, such as:
- Irregular menstrual cycles in teenage girls
- Excessive body hair (hirsutism) and severe acne
- Rapid growth during childhood but shorter stature as an adult
- Fertility problems in both males and females
In both forms of CAH, hormonal imbalances can have a significant impact on your child’s physical development and overall health. If any of these signs are present, it’s important to consult a healthcare provider for further testing.
