A shorter menstrual period can be caused by various physiological and lifestyle factors, including rapid weight loss, intense athletic training, extreme stress, hormonal contraceptive use, thyroid imbalances, perimenopause, or underlying medical conditions like polycystic ovary syndrome (PCOS). When hormonal signals that build up the uterine lining are altered, the resulting shedding phase can become noticeably lighter and briefer than an individual's normal baseline duration.
