Hyperprolactinemia and Brain Health: Exploring the Gut-Brain Axis and Therapeutic Strategies

Prolactin is a pituitary anterior lobe hormone that plays a crucial role in milk secretion from the mammary glands. Hyperprolactinemia is a common endocrine disorder characterized by abnormally elevated levels of prolactin in the serum. Recent research findings indicate that prolactin also exerts important physiological effects beyond lactation, including effects on brain health and the central nervous system. The gut-brain axis has become an important area of neuroscience research, providing insights into the complex interactions between the gastrointestinal system and the central nervous system. Future research may involve developing new probiotic therapies or optimizing the gut microbiota through dietary and lifestyle interventions. In addition, understanding the mechanisms by which hyperprolactinemia contributes to various neurological disorders and targeting prolactin for treatment are crucial areas of research. Therefore, this study aimed to investigate the correlation between hyperprolactinemia and brain health from the perspective of the gut-brain axis, with the goal of discovering new approaches for preventing and treating neurodegenerative and mental health conditions. This synthesis highlights potential strategies for future therapeutic interventions.
