Menorrhagia in women at the age of 40 is a form of premature ovarian failure, which cannot be completely cured at present, but can be treated with the aid of a comprehensive regimen. For patients with amenorrhea at age 40, this method can be applied as early as possible if there are no contraindications to the application of hormone replacement therapy. If a woman has early amenorrhea, she is prone to aging, cardiovascular diseases and metabolic problems, or recurrent urinary tract infections, vaginal inflammation, as well as the risk of bone loss and even fractures. Under the guidance of a physician, rational application of medications can be used for treatment, which can supplement estrogen to relieve symptoms of osteoporosis, avoid cardiovascular disease, and improve vaginal dryness. In addition, patients are advised to consume foods containing estrogen in moderation, such as soy products, kelp, nori, black beans, etc., which can stimulate estrogen secretion, and pay attention to good living habits and avoid staying up late, etc., which can help improve amenorrhea.
