A Parent and Caregiver's Guide to Non-Acquired IGHD

At a Glance

Non-Acquired Isolated Growth Hormone Deficiency (IGHD) is a genetic or congenital growth disorder. With early diagnosis, proper testing, and consistent growth hormone therapy, most children with IGHD can achieve a normal adult height and maintain excellent overall health.

Welcome to this comprehensive resource guide on Non-Acquired Isolated Growth Hormone Deficiency (IGHD). This guide is specifically designed for parents and caregivers to help you navigate your child’s diagnosis, understand the underlying biology, and make informed decisions about their treatment and future.

Receiving a diagnosis of a genetic or congenital growth disorder can feel overwhelming, but the path forward is well-established. With early diagnosis and consistent treatment, most children with IGHD can reach a normal adult height and maintain excellent health.

This guide is broken down into several focused sections. Please use the links below to navigate through the topics:

05

Standard Treatment: Growth Hormone Therapy

Learn about standard growth hormone therapy for Isolated Growth Hormone Deficiency (IGHD). Compare daily vs. weekly injections, dosing, and potential side effects.

06

Growing Up: Transitioning to Adult Care

Learn about transitioning to adult care for Isolated Growth Hormone Deficiency (IGHD). Understand re-testing, adult dosing, and the role of GH in adult health.

Common questions in this guide

What is non-acquired IGHD?
Non-acquired isolated growth hormone deficiency is a congenital or genetic disorder where a child's pituitary gland does not produce enough growth hormone. With early diagnosis and treatment, most children can reach a normal adult height.
How is IGHD in children diagnosed?
Diagnosis typically involves a series of tests to confirm the deficiency. This includes growth hormone stimulation tests, bone age X-rays, and an MRI of the pituitary gland.
What are the genetic subtypes of IGHD?
There are four primary genetic subtypes of IGHD: Types IA, IB, II, and III. Identifying your child's specific subtype helps pediatric endocrinologists determine the safest and most effective treatment path.
What are the standard treatment options for IGHD?
The standard treatment is growth hormone therapy. This is usually administered through daily injections using an easy-to-use auto-injector pen, though newer once-weekly injection options are now available.
Will my child need IGHD treatment as an adult?
When your child finishes puberty, they will transition to an adult endocrinologist and be re-tested. At this stage, treatment goals shift from promoting height to supporting overall metabolic health.

Questions to Ask Your Doctor

Curated prompts to bring to your next appointment.

  1. 1.What specifically led you to suspect non-acquired IGHD for my child?
  2. 2.What is the communication process with your office if we hit roadblocks with insurance prior authorizations for treatment?
  3. 3.How will the care team coordinate with my child's pediatrician for general health checkups?
