Endometriosis Symptoms: Abnormal Periods

Endometriosis Symptoms: Abnormal Periods

What are abnormal periods?

The first fundamental symptom of endometriosis, is abnormal periods. Abnormal periods can include the following symptoms which start before one’s cycle or with the onset of their period:

endometriosis symptoms - Abnormal periods (including: Heavy menstrual flow (menorrhagia) and prolonged periods)
  • Painful menstrual cramping (dysmenorrhea) not relieved by NSAIDs/Ibuprofen. *It is important to note that not all patients with endometriosis have uterine cramping pain or heavy periods. Their symptoms may be elsewhere but still cyclical in nature*

  • Heavy menstrual flow (menorrhagia)

  • Nausea/Vomiting

  • Gassiness

  • Diarrhea

  • Painful bowel movements or urination

  • Chronic pelvic pain

  • Leg Pain (neuropathy)

  • Headaches or Migraines

  • Fatigue

If a patient experiences any of the above symptoms consistently during periods or in a cyclical nature during the month, she should alert her gynecologist.


Monthly vomiting, painful bowel movement, and excruciatingly painful pelvic and menstrual pain is normal during one’s period.


Regular vomiting, painful bowel movements, and abnormal pain during one’s period is not normal. Patients know their body best, and if they are experiencing abnormal pain, they should consult a gynecologist.

What is the distinction between abnormal periods and painful periods

Painful menstrual cramping correlates with this primary symptom of abnormal periods. The reason why they are listed as two separate symptoms is because painful periods can include more than just painful menstrual cramping. On the other hand, abnormal periods are not just limited to painful periods. It is possible for a woman to experience an abnormal period and endometriosis, without her period being particularly painful as she can experience any of the other following symptoms listed above.

Is endometriosis defined by painful periods?

Simply having painful periods does not mean that a woman will have the disease. For example, a thirteen-year-old girl with painful periods would not be diagnosed with endometriosis based solely on this symptom, but rather, such a complaint should certainly prompt a physician to look for other possible symptoms that could confirm that the disease is materializing. Thus, if a person is suffering from abnormally painful periods, this will not mean that she has endometriosis, but rather it should be investigated further. If a woman is missing school or work due to pain/symptoms this is not normal! If she is taking multiple doses of tylenol/ibuprofen and not getting any relief, this is also not normal.

Treatment options for managing abnormal periods

Managing abnormal periods due to endometriosis is difficult. They can feel debilitating, emotionally taxing, and have a great impact on day to day activities. Nevertheless, there are ways to manage the pain outside, or in addition, to excision surgery:

  • Non-steroidal anti-inflammatory drugs (NSAIDs): NSAIDs relieve pain through reducing inflammation. While the exact cause of endometriosis pain is not fully understood, researchers have often characterized it as a “disease of inflammation.” Thus by reducing inflammation through NSAIDs, particularly during one’s menstrual periods, endometriosis patients have been able to find some relief for their symptoms.

  • Hormonal therapy

    Hormonal therapy: Another characteristic that is believed to define pain caused by endometriosis, is the role of sex hormones, particularly estrogen. A woman’s menstrual cycle is driven by the fluctuation of her sex hormones, estrogen and progesterone. Because endometriosis is a disease of menstruation, women often seek such relief options as birth control as a way to control this hormone fluctuation, and in turn relieve their pain.

  • Holistic approach (Diet modification/alternative therapies like acupuncture): While these may not cure the disease, they can certainly help the pain or bowel symptoms often associated with the disease. 

Hormonal therapy

Keep in mind however, the above medications or therapies are for treating endometriosis symptoms and not the disease itself. Excision surgery is the only definitive way to remove endometriosis in the body. Also, what may work for one person, may not for another. Thus it is important to find the treatment option that is right for each particular case. Even with excision surgery, the best therapies for endometriosis patients really include a complete approach to wellness.

The taboos surrounding abnormal periods

A major hurdle in diagnosing endometriosis early in a woman, is the taboo of talking openly about periods. Many women with exceedingly painful periods beginning with their very first one, often do not say anything when the pain initially starts as they are too embarrassed. They do not realize the pain is abnormal or are shunned by their loved ones and doctors when they do have the courage to say something. Their loved ones or doctors may tell them their pain is normal- and they may spend years in silence dealing with it.

On average, it takes 10 years from symptom onset for an accurate diagnosis of endometriosis to be made. This stems from a lack of knowledge in the general public and even in the medical community. The taboos which prevent open discussion about menstruation and menstrual pain greatly hinder proper endometriosis diagnosis and treatment. Chronic and debilitating pain, vomiting, bloating, and abnormal bowel movements during menstruation are not normal. If a patient is experiencing any of these symptoms during menstruation, they should consult their gynecologist. If their gynecologist does not listen to their symptoms or discounts them, they should seek care with an endometriosis specialist.

How to overcome these taboos

Endometriosis is a disorder that not only affects those with the disease, but also loved ones surrounding the individual. For these reasons, it is crucial to educate adolescents, girls and boys, about the menstrual period and break the stigma surrounding menstruation. Girls and boys alike should be taught about the menstrual cycle, the physiology behind it, and how they are as natural to women as the changes that male adolescents go through. Menstruation and the potential abnormalities with it should be taught in sex education.

Girls: Adolescent girls should be taught what to expect when they get their first period,  and be taught the best ways to handle it, physically, emotionally, and socially. They should be invited to ask questions, and they should expect to be able to get the answers they need without fear of embarrassment. They should be encouraged to track their symptoms and to discuss them with a gynecologist who will listen. The adults who educate girls on this topic can be anyone, including fathers or male doctors or school nurses. As is the case in most situations, the best education and awareness will come from those who have the most knowledge, experience, and understanding.

Boys: The conversation with a boy will likely be neither very long nor very emotional. It doesn’t have to be. But the stigma surrounding a woman’s period cannot be broken if males are not part of the conversation. Males’ attitudes toward periods, which can include unflattering jokes or simply trying to avoid the subject altogether, are a major cause of the stigma, and education can help erase that. If young males learn that the condition could be affecting their grandmothers, mothers, sisters, or, eventually, daughters or affect a women’s ability to bear children.
