Características socio-demográficas de las mujeres españolas con sangrado menstrual abundante. Resultados del Registro nacional de pacientes con sangrado menstrual abundante (Registro SANA)

Abstract

Objective

To describe the socio-demographic, diagnostic and treatment characteristics of patients with heavy menstrual bleeding.

Subjects and methods

An observational, cross-sectional, multicenter, national study was conducted in women of reproductive age (18-49 years) with heavy menstrual bleeding with no organic cause attending routine gynecology consultations in Spain.

Results

This study included 1,039 patients, with a mean age of 37.8 ± 8.1 years. Only 52.1% of the women attended their gynecologist due to bleeding abnormalities and 48.0% were diagnosed during the visit.

Patients with longstanding abnormal bleeding reported alterations in quantity, either alone or concomitant to other abnormalities (heavy/prolonged/irregular bleeding). Only 43.7% perceived changes in current bleeding versus usual bleeding, mainly due to an increased quantity.

The main drugs prescribed for the treatment of heavy bleeding were combined oral contraceptives (mainly estradiol valerate 3-2-1 mg + dienogest 3-2 μg) (63.3%), levonorgestrel intrauterine system (14.3%), and combined treatments (11.9%).

Conclusions

Abnormal bleeding is prevalent. Diagnosis through appropriate assessment is a priority
