Growth is controlled by several hormones, including growth hormone and thyroid hormone. When it does not go as expected, a hormone check can help.
In children
Consider an evaluation if a child is much shorter than classmates, has noticeably slowed growth from one year to the next, or has puberty that is very early or very late. Many short children are healthy, so a doctor's assessment is the way to tell.
In adults
Adult Growth Hormone deficiency can cause tiredness, reduced muscle mass, more fat around the waist and low mood. These symptoms are common and have many causes, so proper testing is needed before any conclusion.
What to bring
Growth charts, previous reports and parents' heights are all useful at the first visit. Treatment is decided only after the cause is clear.
