I believe that most women have a history of dysmenorrhea. In terms of disease, there are two types of dysmenorrhea: a primary dysmenorrhea, also known as functional dysmenorrhea, which accounts for 50%. It often occurs in the period after menarche, mostly in unmarried or married women who are not pregnant, and the symptoms of dysmenorrhea can be reduced or disappear after childbirth; the other is called secondary dysmenorrhea, often caused by endometriosis, pelvic inflammatory disease, etc. The general symptoms of dysmenorrhea are: 1-2 days before menstruation, you start to feel pain in your lower back and abdomen, which can radiate to the perineum and anus when the pain is severe; it is often accompanied by nausea, vomiting, frequent urination, constipation or diarrhea; the abdominal pain can last for several hours or 1-2 days; when the blood flows smoothly, the pain gradually decreases. In individual girls, pale face, cold hands and feet, cold sweat or even fainting may occur when the pain is present, which requires timely treatment. For the treatment of dysmenorrhea, besides symptomatic treatment (oral painkillers), Chinese herbal medicine can be considered. This is the principle of dysmenorrhea, and the medication is based on the principle of activating blood circulation and harmonizing qi and blood. In addition to medication, patients should also pay attention to: 1. 2, pay attention to menstrual rest (bed rest if necessary), should not do strenuous activities, avoid cold and rain. 3, to ensure smooth bowel movements. 4, abstain from sexual life, absolutely forbid intercourse during menstruation. 5. Pay attention to local warmth and avoid eating cold food. 6, correct understanding of menstruation as a normal physiological phenomenon, do not fear, tension, disgust, so as not to aggravate the symptoms, should hold a state of relaxation. The current treatment drugs are as follows: 1, oral contraceptives: oral contraceptives can inhibit ovulation, inhibit the growth of the endometrium, reduce the level of prostaglandins in the blood during menstruation, and inhibit uterine activity. Oral short-acting contraceptives are effective in treating primary dysmenorrhea and are suitable for women with dysmenorrhea who also need contraception, and are not recommended for teenage girls. 2. Prostaglandin synthase inhibitor: Generally, the drug is given continuously for 2 to 3 days before the onset of menstrual dysmenorrhea, because prostaglandins are released in the first 48 hours of menstruation in the greatest amount, and early administration can correct the excessive release of prostaglandin synthesis in the blood during menstruation. If the medication is not given continuously in the first 48 hours, but temporarily when it hurts, it is difficult to achieve pain relief. Commonly used drugs in this category: anti-inflammatory pain (go to pain tablets) 25mg, 3 times a day; ibuprofen 400mg, 3 times a day, due to the significant effect, simple to take (1 to 3 days of medication during menstruation), has been widely used in the treatment of primary dysmenorrhea for many years. 3, antispasmodic sedative: often choose aspirin class, atropine, 654-2, chlorpromazine, etc., start using when dysmenorrhea appears, can achieve better pain relief effect. 4.Calcium channel blocker: 20-40mg of cardiac pain, 10-30 minutes of administration of uterine contractions weaken or disappear, while the pain is reduced, the effect lasts 5 hours, no obvious side effects. 5.Chinese medicine: taking Chinese medicine that activates blood circulation and resolves blood stasis is also very effective, such as Yue Yue Shu Punch, Ai Wei Nuan Gong Wan, Nuan Gong Pregnancy Capsules, Blood Mansions and Stasis Capsules, etc. Of course, the above medicines should be applied under the guidance of a doctor. In addition, several days before menstruation to a few days before the period, drinking ginger sugar water, keeping warm, keeping clear promotion stable and relaxed are also good measures to prevent dysmenorrhea.
