Dysmenorrhea: Dysmenorrhea is a condition that causes severe and recurrent abdominal cramps and pains during menstruation. Uterine contractions happen due to increased production of prostaglandins in the uterine lining; as a result, the endometrium sheds. When there is a decrease in prostaglandins levels, menstrual cramps decreases.
Endometriosis: Endometriosis is a gynecological disorder; it occurs when the tissues lying inside the uterus proliferate and grows outside of the uterus. Symptoms are severe menstrual cramps, pain during intercourse, excessive bleeding, and infertility.
