For women with fibroids, you can usually apply hot compresses to your stomach when you are not menstruating. This is because hot compresses on the stomach at this time will not cause any special adverse effects on the fibroids, and will neither lead to the rapid growth of the fibroids nor cause them to rupture. If a woman’s fibroids are large and she has increased menstrual flow and prolonged menstrual period, it is usually recommended not to apply hot compresses to the stomach during menstruation. This is because hot compresses during menstruation may lead to heavier menstrual flow, and may even cause further prolongation of menstrual period, which is why hot compresses should be avoided during menstruation, and women with large uterine fibroid tumors should undergo surgical treatment as soon as possible.
