hypertrophy
Quick Summary
Hypertrophy refers to the enlargement of an organ or body part. In biology, it's the opposite of atrophy, meaning growth rather than shrinkage.1
Muscle Hypertrophy
Muscle hypertrophy is commonly seen in individuals who engage in strength training. This type of growth is often harmless, but extreme muscle hypertrophy can be associated with steroid use, which poses significant health risks. Muscles adapt to the loads they carry, and activities like weightlifting can lead to muscle fibers with a greater capacity for energy production and force generation.12
Cardiac Hypertrophy
Hypertrophy of the heart, while sounding beneficial, is typically a negative sign. The heart's muscle mass can increase in response to long-term stress, such as hypertension. This enlargement provides more muscle to pump blood, helping to meet increased demands. However, specific types of cardiac hypertrophy can alter the heart's pumping efficiency and economy.3

This enlargement is caused by the formation of increased numbers of tiny fibers (myofilaments) that provide the contractile power of muscles. Thus, while the normal muscle cell might have 2,000 myofilaments, the hypertrophied cell might have 4,000 myofilaments. The workload can now be divided…
