If you’re in your mid-to late 40s and noticing your periods becoming irregular, it could be a sign that you’re entering the menopausal transition, also known as perimenopause. This is a natural phase that occurs as your body approaches menopause. Perimenopause typically spans about four years but can range from a few months to several years. During this period, hormonal fluctuations occur as your ovaries gradually stop releasing eggs. This leads to a drop in estrogen levels, which are among the causes of Irregular Periods in your menstrual cycle.
Additionally, these hormonal shifts can bring about symptoms such as weight gain, hot flashes, sleep issues, vaginal dryness, mood swings, and depression. Perimenopause concludes when you reach menopause, which is defined by the absence of periods for 12 consecutive months.
But before moving further, let’s read in detail about the cycle of period and other reasons for its irregularity.
Menstrual Cycle: Periods and Fertility
The length of a woman’s menstrual cycle can vary, but the average cycle occurs every 28 days. It is also normal for regular cycles to range between 23 and 35 days. The menstrual cycle spans from the first day of a woman’s period to the day before her next period begins. Girls typically begin menstruating between the ages of 8 and 13, with the average age being around 12. In this country, the average age for reaching menopause, when periods cease, is 51. Between the ages of 12 and 52, a woman will experience roughly 480 periods, though this number can be lower if she has been pregnant.
Understanding the Menstrual Cycle
To comprehend the menstrual cycle, it’s essential to know about the female reproductive organs, which include:
- Ovaries: These store, mature, and release eggs.
- Uterus (Womb): This is where a fertilised egg implants and where a baby grows.
- Fallopian Tubes: Two slender tubes that connect the ovaries to the uterus.
- Cervix: The gateway from the vagina to the uterus.
- Vagina
Hormones regulate the menstrual cycle. During each cycle, increasing levels of estrogen stimulate the ovary to mature and release an egg, a process known as ovulation. Concurrently, the uterine lining begins to thicken. In the latter half of the cycle, progesterone aids in preparing the uterine lining for a potential embryo implantation.
The egg moves through the fallopian tubes. If fertilization does not occur, the egg is released outside by the body due to the hormonal changes. The estrogen and progesterone levels drop, causing the uterine lining to shed as menstrual flow. The duration from egg release to the onset of menstruation is approximately 10 to 16 days.

What to Expect from Periods After 40?
As you approach menopause, your body undergoes a transitional phase known as perimenopause, which can span anywhere from 2 to 10 years. During this period, fluctuating hormone levels bring about various changes in your menstrual cycle.
Changes to Anticipate
In your 40s, and possibly even in your late 30s (causes of irregular periods in 30s), the erratic levels of estrogen and progesterone can lead to unpredictable periods. You might notice that your periods become more frequent or, conversely, less frequent. The flow can range from very heavy to unusually light. Occasionally, you may skip one or several periods altogether. It’s important to note that menopause is only confirmed after you’ve gone 12 consecutive months without a period.
Other symptoms associated with your menstrual cycle, such as cramps and irritability, may intensify. On the other hand, you might find that the usual signs of an impending period, like pain and mood swings, become less noticeable.

Symptoms Of Irregular Periods in Your 40s
As you move through the transition to menopause, known as perimenopause, you may notice a variety of changes in your body, some subtle and others more pronounced. Here’s what you might experience:
Irregular Periods
Ovulation becomes less predictable during perimenopause, leading to irregular periods. The intervals between periods may lengthen or shorten, the flow can vary from light to heavy, and you may skip some periods altogether. A persistent change of seven days or more in your menstrual cycle length may indicate early perimenopause, while a gap of 60 days or more between periods often signals late perimenopause.
Hot Flashes and Sleep Disturbances
Hot flashes are a hallmark of perimenopause, varying in intensity, duration, and frequency. Sleep disturbances are common and can result from hot flashes or night sweats, though sometimes sleep becomes unpredictable without these symptoms.
Mood Swings
During perimenopause, you may experience mood swings, irritability, or a heightened risk of depression. These mood changes could be linked to sleep disruption caused by hot flashes, but they may also arise from factors unrelated to hormonal shifts.
Vaginal and Bladder Issues
Reduced estrogen levels can cause vaginal tissues to lose lubrication and elasticity, making intercourse uncomfortable. Lower estrogen can also increase the risk of urinary or vaginal infections and contribute to urinary incontinence due to the loss of tissue tone.
Decreased Fertility
As ovulation becomes irregular, fertility decreases. However, pregnancy remains possible as long as you still have periods. To prevent pregnancy, use contraception until you have gone 12 months without a period.
Changes in Sexual Function
You may notice changes in sexual arousal and desire during perimenopause. Nonetheless, if you enjoyed a satisfying sexual relationship before menopause, it is likely to continue during perimenopause and beyond.
Bone Density Loss
Declining estrogen levels lead to a faster rate of bone loss, increasing the risk of osteoporosis, a condition characterized by brittle bones.
Altered Cholesterol Levels
Lower estrogen levels can negatively affect your blood cholesterol levels. This may result in an increase in low-density lipoprotein cholesterol, known as bad cholesterol, raising the risk of heart disease. At the same time, high-density lipoprotein cholesterol, the good cholesterol, may decrease, further elevating heart disease risk as women age.
Managing Perimenopausal Symptoms
Perimenopause is a natural and normal transition to the next stage of life, and does not inherently require treatment. However, managing the symptoms that accompany this phase is possible, and consulting with your OBGYN can help you determine the most suitable approach for you.
Hormonal Regulation
Low-dose estrogen birth control pills can help manage the discomfort of perimenopausal symptoms by stabilizing fluctuating hormone levels.
Medication for Mood and Hot Flashes
Antidepressants can be beneficial not only for addressing depression but also for reducing hot flashes.
Supplements and Therapies
While taking multivitamins can support your general health, herbal and hormonal therapies are not recommended. Research shows these therapies are no more effective than placebos and may carry certain risks.
Mindfulness and Meditation
Practicing mindfulness and meditation can help manage irritability, depression, and anxiety during perimenopause.
Counseling
Counseling can provide support and strategies for coping with the physical and emotional changes experienced during this time.
Exercise
Regular exercise, including strength training, cardiovascular activities, and yoga, can help you maintain a healthy weight, improve mood, strengthen bones, and lower the risk of cardiovascular and other diseases.
Always consult with a healthcare professional before starting any new treatment or procedure.

Potential Complications
Irregular periods are a common aspect of perimenopause and are usually not a cause for concern. However, it is important to consult your doctor if you experience any of the following:
- Extremely heavy bleeding, requiring you to change tampons or pads every hour or two for several hours.
- Bleeding that persists for more than seven days.
- Bleeding between periods.
- Periods that occur less than 21 days apart on a regular basis.
These symptoms could indicate an issue with your reproductive system that may need medical evaluation and treatment.
