Question:
Male, 2.5 years old, deletion subtype
What are the implications for low cortisol levels in toddler boys with deletion subtype (type 2)? We’ve noticed some more fatigue and he sleeps longer during the night. What can and should be done about it? Our pediatrician ran a blood panel and cortisol came back at 3.7 ug/dL.
Nurse Lynn’s Response:
Cortisol is a hormone that helps the body handle stress, illness, and everyday energy needs. A level of 3.7 µg/dL can sound low, but one single cortisol test does not tell us if your child truly has a problem. Cortisol levels change throughout the day, they are highest early in the morning and lowest at night, so the number only helps us if we know exactly what time the blood was drawn. Kids with PWS can also sleep longer or seem tired for many reasons that are not related to cortisol.
If cortisol really is low, a child may seem more tired, sleep longer, get worn out easily, or have more trouble handling illness. But these symptoms can also happen in PWS for other reasons, which is why careful testing is important. The next step is usually to repeat the cortisol test early in the morning, between 6–8 AM, when levels should naturally be highest. Your doctor may also check ACTH, another hormone that tells the adrenal glands what to do. If the morning level still looks low, the endocrinologist may recommend something called a stimulation test, which checks if the adrenal glands can make more cortisol when needed.
If a child truly has low cortisol, the treatment is simple and safe: most often with a medication called hydrocortisone.
