Convulsions during menstruation may be related to physiological factors, calcium deficiency, epilepsy, etc. 1. Physiological factors: When the patient is overworked during menstruation, it may cause muscle spasms and convulsions. When the patient’s body is cold, it may also cause muscle spasms and convulsions. 2. Calcium deficiency: Calcium ions in the body are lost for various reasons, leading to hypocalcemia and muscle spasms. Because menstruation may cause discomfort and affect the diet, it may lead to hypocalcemia and convulsions. 3. Epilepsy: Menstrual epilepsy, a special type of epilepsy restricted to women, usually starts at the time of the first menstrual period, the onset of which is closely related to menstruation, and the onset of each seizure always occurs within three days before and after the menstrual period, but not at other times. For those who experience convulsions during menstruation, it is recommended that they seek medical advice and intervention and treatment for the cause of the problem.
