glucocorticoid
Meaning of glucocorticoid: A glucocorticoid is a steroid hormone that regulates metabolism and suppresses inflammation, produced naturally by the body or manufactured as medication.
Definition of glucocorticoid
A glucocorticoid is a type of steroid hormone that influences how the body manages glucose, protein, and fat metabolism while also suppressing inflammation and dampening immune system activity. Cortisol is the main glucocorticoid produced naturally by the adrenal glands, released in response to stress and following a daily rhythm.
Synthetic glucocorticoids, including prednisone, dexamethasone, and hydrocortisone, are manufactured to reproduce and often intensify these effects and are prescribed to treat a wide range of conditions involving inflammation or an overactive immune response, such as asthma, allergic reactions, and autoimmune disease.
Because glucocorticoids affect metabolism throughout the body and not only the inflammation being treated, their use is generally monitored, since prolonged or high dose treatment can influence blood sugar, bone strength, and other body systems beyond the immediate condition.
Used in a sentence
A glucocorticoid was prescribed to reduce inflammation associated with the patient's autoimmune condition.
Good to know
Glucocorticoids affect metabolism and immune function throughout the body, not only at the site of inflammation being treated, which is why their broader effects are considered alongside their intended benefit.
Word origin
Where “glucocorticoid” comes from
