Hypertrophy

/haɪˈpɜːrtrəfi/noun

The enlargement of an organ or tissue by growth in the size of its existing cells.

The Greek roots

ὑπέρ
hypér
over, beyond
+
τροφή
trophḗ
nourishment, feeding

Literally: over-feeding

The story of the word

Its pair is atrophy, wasting for want of feeding, and between them the two words cover a great deal of pathology. Physiologists insist on the line between hypertrophy and hyperplasia: the first makes cells bigger, the second makes more of them, and lifting weights does the first. A trained rower's heart and an untreated hypertensive's heart are both hypertrophic, for opposite reasons and with opposite outcomes.
