Pediatric & Young Adult Endocrinology
Newborn Endocrine Concerns
Some endocrine questions begin in the first days of life. What happens next is follow-up and interpretation, not a diagnosis made by a screening test.
When families notice
- Low blood sugar in the newborn period that needed treatment
- Transient neonatal hyperinsulinism during the hospital stay
- An abnormal newborn screening result for congenital hypothyroidism
- An abnormal newborn screening result for congenital adrenal hyperplasia
- A recommendation to see pediatric endocrinology before discharge
What it usually means
A newborn screening result is a signal that something needs confirmation, not a diagnosis. Many results are normal on repeat testing, and some need treatment that starts quickly.
EndoWell follows the endocrine conditions above. Newborn screening also covers conditions outside endocrinology, which are followed by the appropriate specialist.
What I look at
- The hospital course, including how low blood sugars were and how they were treated
- Gestational age, birth weight and feeding
- Confirmatory laboratory testing
- Growth and feeding in the weeks after discharge
- Family history
How I approach it
Neonatal intensive care is part of my training, so these conversations start from experience with how newborns are managed in the hospital.
The first visit is usually about confirming what is actually going on, deciding whether treatment is needed now, and setting a follow-up plan that parents understand.
EndoWell is an independent outpatient practice and is not affiliated with any hospital. Dr. Luisa’s NICU work is separate from EndoWell. EndoWell offers outpatient endocrine follow-up, including for newborns and infants, and does not provide inpatient or NICU care.
When to see me
If your baby had low blood sugar, hyperinsulinism, or an abnormal endocrine result on newborn screening, we can follow up on it.

If the explanation you were given does not fit what you are seeing, a consultation can help you understand the pattern.
