Abnormal Uterine Bleeding:

What is it?

Many tampons and pads

Well-woman basics: period health 101

Before we dive into what’s abnormal, let’s start with what’s normal:

A menstrual cycle is a process where the endometrial lining of the uterus gets thicker, prepping for pregnancy. An average cycle is about 28 days and varies for each woman. If a woman does not become pregnant during her cycle, she will shed her lining. This is known as a period.

A period can be an indicator of overall uterine health, and may give women information that could tell them when to see a doctor.

What can a woman expect with a normal period?

  • Lasts 3-7 days
  • Bleeding 80 ml or less which should require the use of less than 16 regular tampons, 12 regular pads, or 3 full 25 ml menstrual cups during a full cycle

Women should see a doctor about their period if:

  • They experience changes in their cycle
  • They are bleeding longer than 7 days
  • They are passing large clots the size of a quarter
  • They are bleeding in between periods or after intercourse
  • They are experience extreme pain

What are the causes of AUB?7

AUB symptoms can be caused by both structural and nonstructural disease states.

Non-structural causes of AUB may include coagulopathy, ovulatory disorders, endometrail disorders, and/or thyroid disorders.

Structural causes of AUB may include polyps, fibroids, adenomyosis, and or malignancies.

Treating AUB

These are common treatment options and expected recovery times for AUB. Selecting the right treatment is dependent on both a woman’s disease state and their unique needs. For patients suffering from AUB caused by fibroids, refer to the fibroid 101 page

The recovery times listed are not from a single source comparing recovery times. The data listed comes from a variety of sources including clinical studies and recovery guidance provided by major medical institutions.

For hysteroscopic tissue removal: the recovery time is based on estimates provided by the Mount Sinai health system in NY and the guidance they offer to patients based on their clinical experience.

For endometrial ablation: the recovery time is based on estimates provided by the Cleveland Clinic health system and the guidance they offer to patients based on their clinical experience.

For hysterectomy: the recovery time is based on a single randomized control trial comparing short-term outcomes of different approaches to hysterectomy.

You are not alone

48% of US women are confident they could identify the five major parts of the uterus, and even less women could identify the difference between fibroids, polyps, and cysts.1

And yet, 75-80% of people with a uterus will be diagnosed with fibroids at some point in their lives.2

Whether you know a little or a lot about your uterus, it’s not always easy to know what’s normal.

Important Safety Information

The Acessa ProVu system is intended to identify and shrink symptomatic uterine fibroids. The Acessa ProVu system is used by trained physicians during laparoscopic surgery under general anesthesia. Rare but serious risks of this procedure include, but are not limited to, infection, internal injury, blood loss and complications related to laparoscopic surgery and/or general anesthesia. This procedure is not recommended for women who are planning future pregnancy. This information is not medical advice. Please discuss the risks and benefits with your doctor to find out if the Acessa procedure may be right for you.

MyoSure tissue removal system is intended to remove unwanted tissue from the uterus. During a MyoSure procedure, a trained gynecologist inserts the MyoSure device through your vagina and then removes the unwanted tissue from inside the uterus. Use of the MyoSure system is not appropriate for patients who are or may be pregnant, or have signs or symptoms of a pelvic infection, cervical cancer, or previously diagnosed uterine cancer. As with any surgical procedure, there are potential risks including but not limited to internal injury, excessive bleeding, and complications related to anesthesia. Temporary side effects may include cramping, bleeding, fever, and nausea. This information is not medical advice. Please discuss the risks and benefits with your doctor to find out if the MyoSure procedure may be right for you.
