Swoleitis (also known as Swoleosis) is a condition that affects the size of human muscle tissue. If Swoleitis is left unchecked it may cause severe hypertrophy in human skeletal muscle.

People affected by Swoleitis are easily identified by their physical appearance. Sufferers may be referred to as "meatheads", "buff" or "hella swole." Swoleitis is very common in bodybuilder communities.
