Stress plays a large role in irregular or missed periods in many women, according to Everyday Health. Stress suppresses the function of the hypothalamus, which controls the pituitary gland, and disturbances to the pituitary gland can cause disruption in the thyroid and adrenal glands, which control the menstrual cycle and hormone management. Because of this, both good and bad stresses can have a negative effect on the period, causing it to stop.
Reducing stress and finding positive coping methods are effective in getting the menstrual cycle back on track, according to Everyday Health. Taking anti-anxiety medications and meeting with a therapist to discuss problems can be helpful solutions for minimizing stress. Because stresses can be both mental and physical, it is important to look at all aspects of your life to determine if stress is the cause of a missed period.
When a period is more than one week late, or does not appear at all for over one month, visit a doctor to determine if there is another cause. Everyday Health points out that in some cases, ovarian dysfunction, hormonal imbalance or other problems with reproductive processes cause missed periods, as does pregnancy. If pregnancy is possible, take a test to confirm or rule it out.
