Hi, Heavy periods are common women issue and there are many reasons why some women have heavy periods however some or more common than others. These are some common causes that include: Hormone problems. Every month, a lining builds up inside your uterus (womb), which you shed during your period. If your hormone levels aren’t balanced, your body can make the lining too thick, which leads to heavy bleeding when you shed the thicker lining. Second, growths in the uterus such as polyps or fibroids are benign (non-cancerous) tumors that grow within the uterus. While some causes may be easy to treat, others can indicate a serious underlying condition. Whether you notice spotting or heavier bleeding in between periods, it’s important to see your doctor for testing, diagnosis, and treatment options. Other potential other causes of bleeding include stress, change in medications, miscarriage, vaginal dryness. Your doctor will also likely give you a physical exam, including a pelvic exam and test your hormonal levels. This will show us exact issue which can be treated then. Hope I have answered your query.
