If your monthly menstrual flow changes — getting heavier or lasting longer over time — it’s tempting to just buy pads or tampons that are more absorbent and put up with it, especially if you’re approaching menopause and the end of your periods is in sight. But a heavier flow may have an underlying cause that needs immediate attention. So a “wait and see” approach to heavier periods is risky, no matter how old you are. It’s normal to see some fluctuation when you first start having periods and again as you approach menopause. But if you notice changes in your period along the way, it’s a good idea to find out what your body is trying to tell you. Stress and other factors, including some medications, may have an impact on your cycle. But you shouldn’t simply accept an increase in your flow or a consistently heavy flow. And that’s true regardless of your age. A heavier flow one month is often not a cause for concern. But if you experience a noticeable increase in your flow over a few months or have ongoing irregular periods, you should see your doctor to check for an underlying cause. Conditions that may cause heavier bleeding include: Fibroids. Infection. Sexually transmitted diseases. Thyroid problems. Cancer. Endometrial polyps. And these all may need immediate attention. So it’s important to have a thorough evaluation to find out what’s going on. Your doctor should conduct tests specifically to diagnose or rule out these factors
