why females are cranky during period?

More than half of menstruating women have cramp-like pain during their periods. The medical term for menstrual pain is dysmenorrhea. Cramps are usually felt in the pelvic area and lower abdomen, but can radiate to the lower back or down the legs.

Mechanically, cramps are like labor pains. Just as the uterus contracts to open up the cervix (neck of the uterus) and push out a baby, it contracts to expel menstrual blood. Often, after several years of menstruating or after childbirth, the cervical opening enlarges. The uterus doesn't have to contract as much to discharge the menstrual flow, so there is less cramping.

Menstrual pain may also come from the bleeding process itself. When the uterine lining separates from the wall, it releases chemicals called prostaglandins. Prostaglandins cause blood vessels to narrow, impeding the supply of oxygen to the uterus. Just as the pain of a heart attack comes from insufficient blood to the muscles of the heart, too little blood to the uterine muscle might cause the pain of menstrual cramps.

Menstrual pain can have other causes, although these are rare among teenagers. They include tumors, fallopian tube infection, and endometriosis, a condition in which fragments of the lining of the uterus become embedded elsewhere in the body

Because the muscles in the womb contract and it hurts. That is called cramps. Sometimes they hurt so bad that girls who go to school or work can't even go.

Not to worry though, they will go away after awhile and next month or two around the same time they will go away.

That is why they become cranky.

The huge changes in hormones. The hormones cause some crankiness themselves, but they also cause cramps. Wouldn't you be cranky if you had cramps all of the time.

Hormones, Discomfort, Pain, Irritability and men who wonder why we are not smiling like idiots through it all. Do you smile when you're having back pain or any other pain? Would you be happy if you had a period? I didn't think so.

The truth is that a females hormones are raging during that time.

She can instantly change moods; one minute happy, the next, bit-chy.

Raging hormones? Temporary insanity?
