Correlation between subclinical hypothyroidism and menstrual irregularities in reproductive-age women

Subclinical hypothyroidism (SCH) has been increasingly recognized as a potential contributor to menstrual irregularities in reproductive-age women, yet its relationship with menstrual health remains underexplored. Therefore, it is of interest to investigate the correlation between SCH and menstrual irregularities, including cycle length, flow intensity and frequency. Hence, a total of 100 women were assessed for thyroid function and menstrual patterns, with results showing a higher prevalence of irregular cycles in those with elevated TSH levels. Thus, we show the impact of even mild thyroid dysfunction on menstrual health, emphasizing the need for thyroid screening in women with menstrual disturbances. This study advances knowledge by providing evidence that SCH plays a significant role in menstrual irregularities, contributing to better understanding and management of reproductive health.
