Prolaktiin

Prolaktiin is a peptide hormone produced by the pituitary gland in the human body. It plays a crucial role in regulating various bodily functions, including lactation, metabolism, and reproductive processes. Prolaktiin is also known as prolactin.

Prolaktiin is secreted by the lactotroph cells of the anterior pituitary gland. Its levels are typically higher in women than in men, and it is most active during pregnancy and lactation. In women, prolaktiin stimulates the production of milk in the mammary glands, making it essential for breastfeeding. It also helps to regulate reproductive functions, including menorrhagia and amenorrhea.

In addition to its role in lactation and reproduction, prolaktiin also has a significant impact on metabolism, particularly in the regulation of glucose and lipid metabolism. It has been shown to have a mitigating effect on weight gain and obesity, and its levels have been found to be lower in individuals with obesity.

Abnormal levels of prolaktiin have been linked to various medical conditions, including prolactinoma, a type of pituitary tumor that secretes excess prolaktiin, and sheehan syndrome, a condition that results in the destruction of the pituitary gland. Elevated levels of prolaktiin have also been linked to various endocrine disorders, including polycystic ovary syndrome.

Prolaktiin can be measured in the blood using a routine blood test. Treatment for disorders caused by abnormal prolaktiin levels may involve the administration of dopamine agonists, such as bromocriptine, which can help to lower prolaktiin levels.
