THINKING OUTSIDE THE GUT: Could Endometriosis be the culprit behind your Constipation or Bloating?

Did you know that Gastrointestinal (GI) symptoms are as common as gynecological symptoms in women with endometriosis? Do you suffer from bloating and/or constipation? Endometriosis may be the cause of your bloating and/or constipation. Over 90% of women diagnosed with endometriosis actually present with GI symptoms as their initial symptoms. Before we delve into why women with endometriosis present with GI symptoms years before they are diagnosed with Endometriosis, let’s review some basic facts about Endometriosis. There is so much misinformation about endometriosis in media, so let’s set the record straight with facts about endometriosis.


What is Endometriosis?


Endometriosis is an inflammatory condition which occurs when cells similar to those found in the lining of the uterus (endometrium) are found external to the uterus. More specifically, it occurs when cells similar to endometrial glands and stroma are found in locations other than the lining of the uterus.  


How many women are affected by Endometriosis?


Endometriosis is common affecting 176 million women worldwide. It occurs in 7-15% of women.   


What are symptoms of Endometriosis?
The symptoms of endometriosis vary and can include all of the listed symptoms below, some of the symptoms, only one symptom in some cases, or no symptoms other than infertility.


  • Pelvic pain during menses, before menses, after menses and/or anytime during the month
  • Constipation
  • Bloating
  • Painful intercourse with deep insertion or certain positions
  • Right and/or Left sided pelvic and abdominal pain
  • Diarrhea
  • Painful bowel movements
  • Lower back pain
  • Heavy or irregular periods
  • Urinary frequency, and/or urgency, and/or painful urination
  • Fatigue
  • Malaise
  • Infertility


Symptoms of Endometriosis


The symptoms of endometriosis can be related to the areas where endometriosis invades. Endometriosis of the uterosacral ligaments/cul-de-sac often leads to painful intercourse, constipation, diarrhea and painful defecation. Endometriosis on the ovary can lead to left sided or right sided pain. Bladder endometriosis may lead to urinary frequency or urgency. You may have only one of the above symptoms or many. Even one symptom can be suggestive of Endometriosis. Many of women do not have any symptoms listed above, and only discover they have endometriosis when they are having trouble conceiving.  If your doctor told you that you have ‘unexplained infertility’, endometriosis is the culprit in 40-50% of cases of unexplained infertility. Dr. Orbuchs’ surgical Excision of endometriosis decreases inflammation and can improve fertility.


Where is Endometriosis found?
Endometriosis has been reported in every organ except the Spleen! More commonly, endometriosis is found on the ovaries, bowels, bladder, uterus, cul de sac (the area in front of the rectum and behind the cervix/vagina and uterus), appendix, and abdominal wall. It also can occur on the diaphragm, lungs, surgical scars and less commonly throughout the rest of the body.


Treatment of Endometriosis


Laparoscopic surgery is the definitive method to diagnose and treat endometriosis. Excision of Endometriosis is the gold standard treatment for endometriosis. Ideally all endometrial lesions should be excised. Unfortunately most gynecologists are not trained in these advanced surgical techniques for treatment of endometriosis. Others approach endometriosis with laser, electrocautery, coagulation or burning. All of these modalities have been shown to be far inferior to excision using scissors, the method performed by Dr. Orbuch. With scissors, the endometrial implants are removed, but with cautery or a laser (the unskilled surgeons only superficially treat lesions), the lesion remains and continue to cause pain necessitating more surgery. A surgeon utilizing laser may vaporize the surface of the lesion, but still leaves active endometrial tissue below. Deep fibrotic endometriosis usually does not respond well to hormonal suppressive therapy.  Drug therapy may suppress symptoms of endometriosis, but not eradicate the endometriosis.  Adequate surgical excision of endometriosis implants provides the best symptomatic relief and long term results. In addition, surgical excision has been shown to improve fertility rates in women. The definitive treatment of endometriosis is NOT hysterectomy or removal of both ovaries; rather it is the complete excision of endometriosis lesions.


da Vinci Excision of Endometriosis


Advantages of Robotic Surgery


Robotic Surgery is an advanced form of Minimally Invasive Surgery. Minimally Invasive Surgery, which includes laparoscopic surgery, uses small incisions instead of large incisions to perform surgery thus reducing the damage to human tissue. The da Vinci System is a sophisticated robotic platform designed to expand a surgeons capabilities. With da Vinci, small incisions are used to introduce miniaturized wristed instruments and a high-definition 3D camera. This allows Dr. Orbuch to view a magnified, high-resolution 3D image of the surgical site allowing for superior visual clarity of anatomy with up to 10x magnification. At the same time, state of the art robotic and computer technology converts Dr. Orbuchs’ hand movements into precise small movements resulting in extreme dexterity. The robotic ‘wrists’ rotate a full 360 degrees that enable Dr. Orbuch to control the miniature surgical instruments with unprecedented accuracy with a wide range of motion. These technological advancements allow Dr. Orbuch to perform complex surgery with precision, dexterity and control. The da Vinci System enables Dr. Orbuch to perform more precise, advanced techniques and enhances her capability to perform complex minimally invasive surgery.


Risk Factors for Endometriosis
It is important to note that while the following risk factors increase one’s likelihood for endometriosis, there are many women who develop endometriosis without any of the following risk factors:


  • Family history, especially mother or sister. If your mom has endometriosis, you have a 7 times higher risk of developing endometriosis
  • Early menses
  • Early onset painful periods
  • Short frequent menstrual cycles
  • Mullerian abnormalities
  • No children
  • Autoimmune disorders (thyroid, rheumatoid, eczema, food allergies/sensitivities)


Endometriosis and GI Symptoms

Bloating is the most common presenting symptom, and is typically reported by 83% of women with endometriosis1. In addition to bloating, other gastrointestinal symptoms including diarrhea, constipation, painful bowel movements, nausea and/or vomiting are also common symptoms in women with endometriosis. It is also interesting to note that GI symptoms are independent of location of endometriosis lesions in relation to the bowel.  This means that you can have GI symptoms without endometriosis actually infiltrating into the bowel. Your endometriosis lesion may be nearby to your bowel without actually being on it2. It is nonetheless important to remember that for some women, endometriosis can often infiltrate the bowel, distort intestinal anatomy, alter normal bowel physiology, which then can also lead to constipation, bloating, painful bowel movements, diarrhea, nausea and vomiting.


Complicating matters, endometriosis can also present primarily with cyclical bloating and altered bowel habits indistinguishable from Irritable Bowel Syndrome (IBS)3. Many women seek help from a gastroenterologist and are subsequently diagnosed with Irritable Bowel Syndrome long before they seek help from a gynecologist. Here’s a typical and unfortunate scenario…a young woman suffers from constipation and bloating. What does she do? She schedules an appointment with a gastroenterologist. What happens? She undergoes an upper endoscopy and colonoscopy, both of which find no identifiable gastrointestinal abnormalities and is subsequently labeled as suffering from Irritable Bowel Syndrome (IBS).  Has this happened to you? Despite treatments from their GI for IBS, women rarely get better—that’s because endometriosis is the cause of their IBS symptoms. It is therefore critical to establish the diagnosis of endometriosis in order to effectively relieve the gastrointestinal symptoms.
Endometriosis must always be considered in the differential diagnosis of women with GI symptoms. Make sure that your endometriosis is treated properly–see my websites for more information: or or
