Q: What Are Irregular Periods?

Q: When Do Irregular Periods Usually Start?

Short answer: It depends, but irregular periods during menopause usually begin between ages 45 and 55.

Long answer: Though irregular periods can occur at any time, they are often the first sign that a woman has begun the transition into menopause.

Q: How Long Do Irregular Periods Typically Last?

Short answer: It varies for each individual woman, but usually anywhere from a few months to a few years.

Did you know?

A woman is said to have reached menopause when she has not had her period for one year.

Long answer: The amount of time for which a woman experiences irregular periods depends largely upon how long her perimenopause stage lasts. Generally, once a woman begins having irregular periods, they will continue until she reaches menopause or until she treats the source of her symptoms, which is hormonal imbalance.

Q: What Causes Irregular Periods during Menopause?

Short answer: Decreasing levels of estrogen and progesterone in the body lead to menstrual irregularities.

Long answer: The underlying reason that women experience irregular periods during menopause is hormonal change. When the transition to menopause begins, the body begins to produce less estrogen and progesterone, which directly affects the menstrual cycle. Thus, irregular periods are often a sign that the body is heading towards menopause.

Q: Can Other Conditions Cause Irregular Periods?

Short answer: Yes, and for this reason, it is wise to speak with a doctor about irregular periods.

Long answer: A number of physical conditions and lifestyle choices can cause or impact irregular periods. Health causes include, but are not limited to, conditions such as cancer, reproductive disorders, and eating disorders. Poor diet, stress, and inadequate or excessive exercise can also cause or aggravate irregular periods.

Q: Do Irregular Periods Mean That a Woman Is No Longer Fertile?

Short answer: Not necessarily.

Long answer: Recent research shows that many women experiencing irregular periods as they approach menopause have anovulatory cycles, meaning that they do not release an egg and therefore cannot conceive that month.

Did you know?

After the age of 35, average fertility rates in women show a rapid decline.

While this appears to be true for many menopausal women, it is still possible to get pregnant before menopause, despite experiencing irregular periods. Many doctors recommend that women with irregular periods continue to use a reliable form of birth control until they have not had a period for one year.

Q: When Should a Woman Contact Her Doctor?

Although the characteristics of irregular periods may vary from woman to woman, certain warning signs may indicate a more serious condition. If experiencing any of the following, it may be a good idea to speak with a doctor:

  • Soaking through tampon or pad every one or two hours
  • Bleeding that lasts longer than a week
  • Vaginal bleeding after intercourse
  • Vaginal bleeding after menopause
