A genetic cause of short stature. It occurs when a child inherits genes for short height from one or both parents.
Your doctor may ask these questions to check for this disease:
A doctor may need to examine and confirm the diagnosis. There is no specific or proven treatment for this condition. Managing a child's expectations and emotional well-being is important, as they may be victims of bullying or discrimination from peers.

Q.
Below Average? The Science of Average Male Height and Medically Approved Next Steps
A.
There are several factors to consider: the average male height in the U.S. is about 5 ft 9 in, and being below that is common and usually normal, with doctors focusing more on percentiles, growth trends, and red flags like being under the 3rd to 5th percentile, slowed growth, or delayed puberty. Next steps include reviewing family height, tracking growth and nutrition, and seeking care for concerning symptoms; after growth plates close in the late teens to early 20s, natural height increase is not possible and growth hormone is reserved for specific conditions, so see the complete guidance below for details that could change which steps you take.

Q.
Am I Too Short? Why Average Height for Men Varies & Medically Approved Steps
A.
There are several factors to consider: average male height varies by country and genetics, and being below average is usually normal, while medical short stature typically means below the 3rd percentile, about 5 ft 4 in in the U.S. Adults cannot naturally grow taller once growth plates close, though posture may help and surgery carries real risks; if you are still growing, nutrition, sleep, exercise, and timely medical evaluation matter. See below for country averages, causes, red flags for seeing a doctor, and medically approved steps that can guide your next move.
