Though often used synonymously; Trapped Lung and Lung Entrapment technically describe separate entities along the…. In addition, although dopamine agonist drugs, such as bromocriptine, are often efficacious at reducing PRL levels in all hyperprolactinaemic syndromes, both method and duration of curative treatment largely depends on the specific aetiology of the hyperprolactinaemia. Having less than normal thyroid function is a common problem and is easily tested and treated.

Abnormal hormonal function affects both women and men

The absolute PRL levels have considerable diagnostic and predictive value because the serum PRL concentrations are consistently elevated in patients with prolactinoma.
