Endometriosis is a chronic condition defined by the presence of tissue similar to the uterine lining growing outside the uterus, causing inflammation, pain, and scar tissue formation. This disorder affects an estimated 10% of women of reproductive age globally. The disease can involve multiple organs and presents with a wide range of symptoms, including severe pelvic pain, painful intercourse, and infertility. Navigating the healthcare system to find appropriate providers is challenging, making the choice of physician particularly important for diagnosis and effective management.
Starting the Journey: Primary Care and Initial Referrals
The first step in seeking care for symptoms like severe menstrual cramps, chronic pelvic discomfort, or pain during bowel movements often begins with a Primary Care Provider (PCP). PCPs function in the initial recognition of symptoms that may indicate endometriosis, especially since these symptoms can overlap with other common conditions like irritable bowel syndrome (IBS) or urinary tract infections (UTIs). They take a thorough patient history, including details about the cyclical nature and severity of pain, which is characteristic of endometriosis.
A high index of suspicion in the primary care setting can help reduce the delay in diagnosis, which often averages several years. The PCP’s role is to rule out non-gynecological causes of pain and to initiate first-line treatments such as Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) or hormonal contraceptives. If initial medical management is ineffective, or if the patient reports persistent symptoms, the next action is a timely referral to a gynecologist for further investigation and specialized care.
The Core Specialist: Obstetrician-Gynecologists (OB/GYNs)
The Obstetrician-Gynecologist (OB/GYN) is the specialist most commonly consulted for a suspected diagnosis of endometriosis and manages the majority of cases. A general OB/GYN handles the standard diagnostic workup, which often involves a physical exam and imaging such as transvaginal ultrasonography. Ultrasound is a preferred first-line imaging test because it is accessible and can identify endometriomas (ovarian cysts caused by endometriosis) and deep infiltrating lesions, which helps guide the treatment plan.
While surgical visualization via laparoscopy remains the definitive method for histopathological confirmation, current guidelines support a clinical diagnosis based on symptoms and imaging to expedite the start of treatment. Medical management focuses on hormonal suppression to reduce the growth of the endometrial-like tissue and manage pain. Treatments include combined oral contraceptives, progestins, or gonadotropin-releasing hormone (GnRH) agonists, which are commonly prescribed and monitored by the general gynecologist.
For patients whose symptoms are not adequately controlled by medication, the OB/GYN may perform a diagnostic and operative laparoscopy. During this procedure, the surgeon aims to remove visible lesions to reduce pain while preserving reproductive organs. However, general OB/GYNs may utilize ablation, a technique that burns the surface of the lesions. This technique can leave the deeper tissue intact and may result in higher recurrence rates.
Advanced Care: Endometriosis Excision Specialists
For individuals with severe, recurrent, or deep infiltrating endometriosis (DIE), which may involve organs like the bowel or bladder, a higher level of surgical expertise is necessary. An Endometriosis Excision Specialist, often a fellowship-trained minimally invasive gynecologic surgeon (MIGS), possesses the advanced skills required for complex cases. The defining difference in their approach is the use of excision—meticulously cutting and removing the entire lesion—rather than ablation.
Excision surgery is considered the superior surgical method for achieving long-term symptom relief, as it minimizes the chance of the disease recurring compared to surface-burning techniques. Identifying such a specialist involves asking about their specific training, their surgical volume for endometriosis, and their preferred technique, as they focus on complete excision. These specialists often operate with a multidisciplinary team for extensive disease, ensuring that affected surrounding organs are handled by the appropriate subspecialist, such as a colorectal or urologic surgeon. The goal of this surgery is the complete removal of all visible disease, which is important for those attempting to preserve fertility.
Assembling the Multidisciplinary Support Team
Because endometriosis is a chronic disease, a single physician cannot address all aspects of the condition; therefore, a multidisciplinary team approach is recognized as best practice. Beyond the gynecologic surgeon, various adjunct providers are needed to manage associated symptoms. Pelvic Floor Physical Therapists are involved to address chronic pelvic pain stemming from muscle tension and dysfunction, which often accompanies the disorder.
For patients experiencing significant bowel symptoms, such as pain or constipation, a Gastroenterologist may be consulted to manage the gastrointestinal aspects of the disease. A Pain Management specialist can offer non-surgical treatments for persistent pain rooted in nerve sensitization, employing strategies that include nerve blocks or specific pain medication regimens. Mental Health professionals, such as counselors or psychologists, are also a valuable part of the team to provide coping mechanisms and support for the emotional toll of chronic pain and delayed diagnosis.
