Which term indicates excessive secretion or discharge?

The term "hypersecretion" is the correct answer because it specifically refers to the condition in which there is an overproduction or excessive secretion of a substance, typically hormones or other fluids, by a gland or organ in the body. The prefix "hyper-" denotes an increase or excessive level, while "secretion" refers to the process by which substances are produced and released from cells or glands.

In contrast, "hyposecretion" indicates a deficiency or insufficient secretion, leading to lower levels of the substance being produced. "Seborrhea" describes a condition associated with excessive oil production on the skin, particularly the scalp, but it does not generally apply to all types of secretion across different organs. The suffix "-rrhea" relates to flow or discharge but is too broad and does not specify whether the secretion is excessive or deficient. Therefore, "hypersecretion" is the most precise term for indicating excessive secretion or discharge.
