It is important to know that GHD is no one’s fault. Sometimes, the exact cause remains a mystery (doctors call this "idiopathic"). When we can pinpoint the cause, it usually falls into one of two categories:

1. Congenital GHD (Born with it) This happens when a child is born with genetic mutations that affect how their brain and body produce growth hormones. In the Middle East, where large, close-knit families and shared genetics are common, we sometimes see specific inherited patterns. Depending on the exact genetic type, your child might have no natural growth hormone at all, or just very low levels. Some of these conditions are also tied to physical signs, like a cleft palate.

2. Acquired GHD (Developed over time) This occurs when the pituitary gland—the tiny "control center" in the brain that releases growth hormone—gets damaged. This damage can happen to both children and adults due to:

• Benign (non-cancerous) tumors in or near the pituitary gland.

• Severe head injuries.

• Brain surgeries or radiation therapy.

• Infections in the central nervous system.

We typically see two main "windows" where parents bring their children in for evaluation:

• Around age 5: When children start school and parents notice a height difference compared to classmates.

• Ages 10 to 16: When a delay in the normal teenage growth spurt or puberty becomes noticeable.

To figure out exactly what is going on, Dr. Marlin will review your child’s growth charts and medical history. We want to rule out other common causes of slow growth, like celiac disease, thyroid issues, or simple undernutrition.

If we suspect GHD, we will walk you through a few gentle tests:

• Bone Age X-Ray: A quick X-ray of your child's hand to see if their bones are growing at the expected rate.

• Blood Tests: Simple tests to check levels of specific proteins linked to growth (like IGF-1).

• Growth Hormone Stimulation Test: Because natural growth hormone levels bounce up and down all day, a standard blood test isn't enough. We will give your child a safe medication to "wake up" their pituitary gland, then check if the gland releases the right amount of hormone.

• MRI Scan: A safe, painless picture of the brain to ensure the pituitary gland looks healthy.

The primary treatment for GHD is straightforward and highly effective: synthetic growth hormone injections.

We understand that giving your child a daily shot at home might sound overwhelming at first. Please do not worry—the needles are incredibly tiny, and our team will teach you exactly how to do it safely and comfortably. Treatment usually lasts for several years, and we will see you regularly to adjust the dose as your child grows.

Are there side effects? Serious side effects are very rare. Occasionally, children might experience mild headaches, achy muscles, or slight swelling in their hands and feet. If your child experiences a severe headache or hip pain, let us know immediately so we can adjust their dosage.

There is wonderful news for families dealing with GHD: early treatment works beautifully. When caught early, most children catch up and reach a near-normal adult height. It is common for children to grow up to 10 centimeters (4 inches) in their very first year of treatment, and another 7.5 centimeters (3 inches) or more each of the following two years!
