Variations in your menstrual cycle happen on occasion, but if you notice consistently heavier periods – it can be of concern. Here are some reasons you may be experiencing this change in your menstrual cycle and what you can do about it.

For most women of child-bearing age, menstrual cycles are a regular part of life. While slight fluctuations in your flow are common, consistent changes such as progressively heavier periods can be concerning. 

If you've noticed that your periods have become significantly heavier than usual and are interfering with your quality of life, it’s time to seek medical care and explore potential causes. 

Here at Women’s Care of Beverly Hills in South Bay, Redondo Beach, and Beverly Hills, California, our expert OB/GYN team wants to help you ease heavy periods and improve your quality of life.

Read on to learn more about some of the potential reasons behind heavier periods and what you can do to manage them.

What is considered a “heavy” period?

Heavy periods are medically called menorrhagia. They’re defined by menstrual bleeding that lasts more than seven days or is very heavy. Your period is considered heavy if you:

  • Pass blood clots the size of a quarter or larger
  • Change your pad or tampon after less than 2 hours
  • Need to change your sanitary supplies in the middle of the night

This degree of heavy bleeding deserves an evaluation at our office.

What are the causes of 'heavy’ periods?

Heavy periods have many potential causes. Some are more serious than others. We evaluate you with imaging tests and blood tests to look for:

Hormonal imbalances

Hormonal fluctuations can significantly impact your menstrual cycle. An imbalance in hormones, particularly estrogen and progesterone, can lead to heavier periods. Conditions such as polycystic ovary syndrome (PCOS) and hormonal birth control methods can affect hormone levels. In cases of hormonal imbalance, we can recommend treatments or therapies to regulate your menstrual flow.

Uterine fibroids

Uterine fibroids are noncancerous growths that develop within the walls of the uterus. As many as 80% of women develop fibroids by the time they reach the age of 50. These growths can vary in size and may lead to heavier menstrual bleeding, longer periods, and pelvic pain. If you suspect uterine fibroids, consult with us to get a proper diagnosis and discuss treatment options. 

Treatment may include medication or surgical procedures.


Adenomyosis is a condition in which the tissue that lines the uterus (endometrial tissue) grows into the muscular wall of the uterus. This can cause the uterus to become enlarged, leading to heavier periods, severe cramping, and discomfort. Treatment options may include pain relief medication, hormonal therapy, or, in some cases, surgery.


Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus. This tissue acts just like that within your uterus, so during your cycle, it bleeds and sheds. As a result, you experience heavy menstrual bleeding, along with pelvic pain and other symptoms. 

Management may involve pain relief medication, hormonal therapy, or minimally invasive surgery to remove the endometrial tissue.

Pelvic inflammatory disease (PID)

PID is an infection of the female reproductive organs, often caused by sexually transmitted diseases (STDs). It can lead to heavier periods, along with pelvic pain and other symptoms. Timely diagnosis and treatment with antibiotics are essential to prevent complications and manage symptoms.

Certain medications

Certain medical treatments or medications, such as anticoagulants (blood thinners) or intrauterine devices (IUDs), can increase menstrual bleeding as a side effect. If you suspect that a medication or treatment is causing heavier periods, talk to us about possible alternative options.

Don’t ignore noticeable changes in your menstrual flow, including heavier periods. Accurate diagnosis and timely treatment can help you manage your symptoms and prevent potential complications.
