Abnormal uterine bleeding is an alteration that has repercussions on the quality of life. It is important to determine its causes in the transition to menopause to provide targeted management and avoid unnecessary surgical interventions. This study aimed to identify the causes of abnormal uterine bleeding in patients transitioning to menopause. It is a study with an observational, descriptive, cross-sectional and prospective design. 40 patients were analyzed, the age was 45 to 49 years, with an average of 46.4 years, predominating the 45-year-old group. An approach was performed to search for the cause of abnormal uterine bleeding according to the acronym PALM-COEIN, in addition to histological analysis of the endometrium. We found that 82.5% of the cases are of a dysfunctional type and 17.5% are of a structural cause. It was concluded that the most common cause of SUA in the transition to menopause is dysfunctional. The structural causes that mostly occur in order of frequency are uterine myomatosis, adenomyosis, endometrial thickening and endometrial polyp.
