Evidências sobre a influência dos fitoestrógenos nos sintomas do climatério

Abstract

The menopause represents the natural end of the reproductive period. The climacteric period is accompanied by physical and emotional symptoms that impact on a woman's quality of life. Phytoestrogens are bioactive compounds found in plant-derived foods that act in a similar way to female hormones such as oestrogen and may interfere with climacteric symptoms. This study aims to identify evidence on the influence and effects of phytoestrogens on climacteric symptoms. This is a narrative literature review carried out in the Virtual Health Library and PubMed databases using the descriptors menopause, phytoestrogens, climacteric and phytotherapy. In the selection process, 10 articles were identified. Evidence indicates that phytoestrogens, alone or in combination with other phytoestrogenic compounds, as well as with vitamins and minerals, can exert beneficial effects. It is concluded that there is evidence of the action of phytoestrogens on climacteric symptoms in menopausal women, and that they may be a promising alternative for reducing hot flushes, hot flashes, insomnia, fatigue, irritability and quality of life in women.
