Breaking Down Hypertrophy

When the prefix hyper-, "above, beyond", is joined to -trophy, we get the opposite of atrophy. An organ or part becomes hypertrophic when it grows so extremely that its function is affected. Muscle hypertrophy is common in men who do strength training, and is often harmless; but extreme muscle hypertrophy generally involves taking steroids, which can do great damage to the body. Hypertrophy of the heart sounds as if it might be healthy, but instead it's usually a bad sign. Hypertrophy, like atrophy, can be used in nonmedical ways as well to describe something with exaggerated growth or complexity.
