Why Do Women Get
Menstrual Cramps?
When girls reach puberty, which usually begins between 10 and 15
years of age, they begin menstruating so that their bodies can prepare to have babies
in the future. This sexual maturation brings about a host of processes and
symptoms that are uncomfortable, including menstrual cramps.
What are Menstrual Cramps?
Menstrual
cramps occur just before and during a woman's monthly menstrual period. During
this time, the uterus contracts to expel the nutrient-rich lining that would
have hosted an embryo had she become pregnant during her cycle.
The
release of blood and tissue from the vagina is associated with menstrual
cramping because the contracting uterus expels its unused contents so it can
start over again for the next menstrual cycle.
Why Cramps Happen
Menstrual
cramps occur in girls and women who are experiencing monthly periods. Some
women experience pain as their uterus begins to contract and get rid of the
excess tissue that is inside of it.
During
menstruation, the body releases prostaglandins---hormones that induce uterine
contractions---that can lead to cramping. These hormones signal for the
uterus---a muscle---to contract so that it can release the tissue from within
it so that it can prepare to host a possible pregnancy next month. These are
the same hormones that help the uterus to squeeze out a baby during childbirth.
The more prostaglandins a woman's body produces, the more intense her cramping
will be.
