Irregular periods do not necessarily mean menopause. Your doctor can determine menopause and also check for unexpected pregnancy. Technically, menopause doesn't occur until a woman has gone a full 12 months without a monthly period. Some symptoms can occur before menopause, though, as estrogen levels begin to change.
Irregular periods can be a sign of menopause, but not always. Lots of things can affect your period: stress, weight changes, thyroid disease, even pregnancy. Your cycle can become erratic, but get itself back on track. If you’ve stopped having your period for a year, though, you are menopausal. Of course, other symptoms of estrogen lack may also signal the start of menopause.
Irregular periods can be caused by many things, including the beginning of menopause. The control of our menstrual cycles is a result of the communication between the brain and ovaries. The messengers are our hormones. In a feed back system between the brain and the immature eggs, or primoridial follicles, an egg is selected for ovulation and the lining of the uterus grows and matures. After ovulation, the hormone levels gradually drop and then the uterine lining sloughs off. This is the menstrual period.
In a very young girl, just beginning her periods, her ovaries are loaded up with immature eggs but her brain is still immature. This is why early periods are irregular. At the end of the reproductive years, the primoridal follicles are greatly reduced in number, and the subsequent production of the hormone messengers is less regular. This can result in menstrual cycle changes. Often periods get closer together and flow may be heavier. This may happen as early as the early 40's. Later periods can be skipped. Half of women will stop having periods by age 51 years. Almost all women will stop by age 55 years.
But, irregular periods can be caused by many different issues and you should contact your health care provider to investigate what is going on with you.
New irregular periods in women over the age of 40 could be the beginning of the transition into menopause, especially if there are other associated perimenopausal symptoms. Any new irregular period should be discussed with an OBGYN.
