## TL;DR

A case study explores the challenges of managing a patient with both PCOS and idiopathic hyperprolactinemia, emphasizing the need for a multidisciplinary approach.

## Contribution

This case highlights the diagnostic and management complexities when idiopathic hyperprolactinemia coexists with PCOS.

## Key findings

- The patient showed amenorrhea, weight gain, and elevated prolactin levels without pituitary abnormalities.
- Dopamine agonist therapy and lifestyle modifications were used alongside continuous monitoring.
- The case underscores the need for further research on neuropsychiatric effects of prolactin dysregulation.

## Abstract

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder often presenting with menstrual irregularities, hyperandrogenism, and metabolic dysfunction. Hyperprolactinemia, characterized by elevated prolactin levels, may share overlapping features with PCOS and complicate diagnosis. When these two conditions coexist, they present unique clinical and management challenges.

A 25-year-old woman with a history of PCOS presented with amenorrhea, progressive weight gain, and irregular menstrual cycles. Laboratory investigations revealed persistently elevated prolactin levels, while pituitary imaging ruled out structural abnormalities. The patient received lifestyle modification advice and dopamine agonist therapy, with continuous monitoring of hormonal, metabolic, and psychological parameters.

This case highlights the diagnostic complexity of idiopathic hyperprolactinemia occurring in the context of PCOS, and emphasizes the importance of a multidisciplinary approach to management. Further clinical observations are needed to understand the neuropsychiatric effects of prolactin dysregulation.
