Some women may experience greater mood swings and even short tempers during menstruation due to greater changes in hormone levels in the body. That is, after the estrogen and progesterone in the body drop to low levels all of a sudden, the endometrium loses the support of these two hormones, peels off and bleeds, and menstruation comes. During this period, some women may experience depression, nervousness, anxiety, and some may be grumpy and cry, etc. When the hormones in the body are stabilized, the emotions will gradually stabilize. During menstruation, women need to ensure adequate sleep, properly regulate their emotions, and avoid excessive emotional ups and downs, which has a positive effect on both physical and mental health. If the symptoms of mood swings are severe, or if the temper tantrums persist and do not improve, the patient should go to the hospital in time for treatment.
