Condition analysis: Drinking milk will not aggravate dysmenorrhea, because during menstruation, many vitamins and minerals in the body will be lost with menstrual blood. Drinking milk during menstruation is easier to absorb various vitamins, calcium, iron, zinc and selenium. Suggestion: The diet of dysmenorrhea patients should be light and easy to digest within 3-5 days before menstrual cramps. They should eat food that is easy to digest and absorb, and should not eat too much, especially avoid eating cold food, because cold food will stimulate the contraction of uterus and fallopian tubes, thus inducing or aggravating dysmenorrhea. When menstruation comes, we should avoid all cold, indigestible and irritating foods, such as peppers, raw onions, raw garlic, peppers and spirits.
