Can depression and anxiety cause your periods to stop (amenorrhea) or at least cause a missed period?

Amenorrhea is the absence of menstruation in females. This condition typically excludes any absent menstruation (periods) for normal female function, such as before puberty, during pregnancy and/or breastfeeding or after menopause.

The abnormal absence of menstruation may be due to any number of changes in the organs, glands and hormones involved in the menstrual cycle. Possible medical causes of amenorrhea may include ovarian failure, problems in the central nervous system or the pituitary gland, hormonal imbalances, poor nutrition, stress or illness.

Amenorrhea may sometimes be accompanied by other symptoms, which may indicate that an underlying condition is present. For instance, when accompanied by acne, excessive hair growth (hirsutism) and rapid weight gain, amenorrhea may be caused by a hormonal imbalance associated with polycystic ovarian syndrome (PCOS). When accompanied by extreme weight loss, hair loss and other signs of malnutrition, it may indicate an eating disorder, such as anorexia nervosa.

Once it is determined that amenorrhea is not due to pregnancy, lactation or menopause, treatment will be determined based on the underlying condition. Treatments include diet and nutrition modifications, stress reduction techniques, birth control pills or hormone replacement therapy and, in rare cases, surgery.

Unless caused by a medical condition, menstrual irregularities such as amenorrhea may be prevented by maintaining a healthy lifestyle that includes a balanced diet and moderate exercise with plenty of rest. In addition, women should see their obstetrician-gynecologist (ObGyn) once a year for regular check-ups and report any irregularities or changes in their menstrual cycle to their physician

Yes.

Wow that would explain a lot! I get panic attacks and depression and last year I missed my period for nine months! (and I wasn't pregnant, I promise!)

Yes
somtimes
but the next time you get it it will be a hevey flow!
so be carful

Yes stress can definitely cause your period to interrupt the normal flow of your period. I was worried about my ex-boyfriend recovering from getting shot twice and I missed a month of my menses. So its very likely, but just to get a clear and precise diagnosis visit a doctor.

Yes it can. And so when a condom slipped off, I didn't tell my girlfriend--I worried alone until she had her next period. It would have been worse to have her miss one because she was worrying, too. Whatever was done was done, and there would have been plenty of time to deal with it afterward. But I do believe this resolved the question more quickly and she didn't have to worry.
