Endometriosis affects an estimated 190 million women and girls of reproductive age globally. It is a chronic gynecologic disease associated with severe pain, infertility, and mental health ramifications. There is currently no known cure for endometriosis, and treatment is usually aimed at controlling symptoms. Despite its prevalence, endometriosis often goes undiagnosed or misdiagnosed, underscoring the need for increased awareness, early detection, and research efforts to offer women the hope of a pain-free future and improved quality of life. This article will highlight top functional medicine labs integrative practitioners utilize to evaluate, manage, and treat patients with endometriosis.

What Is Endometriosis?

Endometriosis is a complex gynecological disorder that affects up to 10% of women worldwide. Characterized by the abnormal growth of endometrial tissue outside the uterus, this condition can lead to debilitating pain and fertility challenges. During each menstrual cycle, this implanted tissue behaves similarly to the endometrium within the uterus, thickening, breaking down, and bleeding. However, unlike the uterine lining, which can be expelled during menstruation, the displaced endometrial cells have no exit route. As a result, they become trapped within the pelvic region, forming painful lesions on organs such as the ovaries, fallopian tubes, and even the bowel and bladder. (2, 15) 

What Causes Endometriosis?

The exact cause of endometriosis remains unknown. However, several theories and factors are believed to contribute to the development of endometriosis. 

Retrograde Menstruation

One of the leading theories is retrograde menstruation, where menstrual blood, along with endometrial cells, flows backward through the fallopian tubes and into the pelvic cavity instead of being expelled from the body. These displaced endometrial cells can implant and grow on pelvic organs, leading to endometriosis.

Genetics

There is evidence to suggest that endometriosis may have a genetic component. Women with a family history of the condition are at a higher risk of developing it themselves. Studies point to genetic variations that affect the body's estrogen response and immune system function contributing to endometriosis development (15). 

Hormonal Imbalance

One of the primary mechanisms suggested by functional medicine is hormonal imbalance, specifically estrogen dominance. Estrogen is responsible for promoting the growth of endometrial tissue during the menstrual cycle. In cases of estrogen dominance, there is an excess of estrogen relative to progesterone, leading to uncontrolled growth of endometrial cells within the uterus and in ectopic locations.

Immune System Dysfunction

Chronic inflammation and immune system dysfunction are considered significant factors in endometriosis. Normally, the immune system would recognize and eliminate ectopic endometrial cells. But when the immune response is compromised, these cells can grow unchecked, forming painful lesions and adhesions.

The presence of endometrial lesions triggers a persistent immune response in the body. The immune system recognizes the ectopic tissue as foreign and tries to eliminate it, leading to further inflammation and tissue damage in the affected areas. The inflammatory nature of endometriosis is responsible for many of the condition's hallmark symptoms, discussed below. 

Environmental Factors

Environmental factors, such as exposure to endocrine-disrupting chemicals (EDCs) in everyday products, may also contribute to the development of endometriosis by interfering with hormonal balance (12). 

Endometriosis Symptoms

Endometriosis can present with a wide range of symptoms, and the severity of these symptoms can vary among individuals. Some common symptoms of endometriosis include (13):

• Pelvic pain: the most prevalent symptom of endometriosis is chronic pelvic pain, which may range from mild to severe. The pain can be continuous or cyclical, intensifying before and during menstruation.
• Painful menstruation (dysmenorrhea): Women with endometriosis often experience unusually severe menstrual cramps, which may be accompanied by lower back pain.
• Painful intercourse (dyspareunia)
• Infertility or difficulty getting pregnant: Endometriosis can lead to fertility challenges in some women, as the presence of endometrial lesions and scar tissue can interfere with the normal functioning of the reproductive organs.
• Heavy menstrual bleeding (menorrhagia): Some women with endometriosis may experience excessive or prolonged menstrual bleeding.
• Painful bowel movements or urination: Endometrial tissue can also grow on the bowel or bladder, causing pain and discomfort during bowel movements or urination.
• Chronic fatigue
• Digestive issues that mimic irritable bowel syndrome (IBS), including bloating, diarrhea, constipation, and nausea

Why Is It Important to Run Functional Medicine Labs Bi-Annually on Your Endometriosis Patients?

In the functional medicine approach to endometriosis, identifying and addressing the root causes of hormonal imbalance, inflammation, and immune dysfunction are key elements in managing the condition and alleviating symptoms. Lifestyle modifications, dietary changes, stress management, and targeted supplementation may be recommended to restore hormonal balance, reduce inflammation, and support a healthy immune response, offering hope for improved outcomes and better quality of life for women living with endometriosis.

Regularly conducting functional medicine labs on endometriosis patients is important for multiple reasons. Firstly, it enables healthcare practitioners to track treatment progress and effectiveness by gaining insights into the patient's overall health, hormonal balance, and inflammatory status. Secondly, it aids in the early detection of potential recurrence or complications, as endometriosis is a chronic condition with recurring risks. Furthermore, these labs help identify underlying factors contributing to the condition, such as hormonal imbalances, inflammation, immune dysfunction, nutrient deficiencies, and gut health issues, allowing for a more targeted approach to management. Tailoring personalized treatment plans based on the individual's unique needs enhances the chances of success and symptom relief. Additionally, comprehensive functional medicine testing assesses overall health, unveiling potential systemic effects beyond the reproductive system. Engaging patients in the monitoring process empowers them to actively participate in their care, fostering better adherence to treatment and lifestyle changes.

Top Functional Medicine Labs to Run Bi-Annually on Your Endometriosis Patients

Described below are some of the top labs that can be considered on a bi-annual basis for patients with endometriosis.

Hormone Panel

The DUTCH Complete is a comprehensive urine test that evaluates hormone levels, adrenal functions, and organic acids. The panel measures sex hormones and their metabolites to assess the balance between estrogen and progesterone, cortisol as a marker of chronic stress, and various metabolic byproducts that reflect inflammation and nutrient status.

Comprehensive Stool Analysis

Research shows significant variations in the gut microbiome in patients with endometriosis compared to those without (2). Dysbiosis contributes to estrogen imbalances, systemic inflammation, and immune dysregulation. A comprehensive stool test can assess the abundance and diversity of the gut microbiome and measure other markers of gut health and estrogen metabolism, to uncover underlying factors contributing to endometriosis and its related symptoms.

Anemia Panel

The most common cause of iron deficiency anemia in menstruating females is blood loss due to heavy periods. Iron deficiency anemia can further exacerbate menorrhagia and fatigue. Therefore, ordering a CBC and iron panel to assess for iron deficiency and anemia can be essential to preventive care. 

Inflammation

Women with endometriosis typically exhibit increased levels of hs-CRP, a highly sensitive marker of inflammation within the body (15). Ordering hs-CRP, potentially in conjunction with ESR (another inflammatory marker), helps quantify systemic inflammation and monitor treatment progress.

Summary

Bi-annual functional medicine labs hold immense promise as a valuable tool in the comprehensive management of endometriosis. By providing a deeper understanding of the patient's hormonal balance, inflammatory status, and overall health, these labs empower healthcare practitioners to tailor personalized treatment plans that address the condition's root causes. Regular monitoring allows for timely interventions, ensuring early detection of potential complications or recurrence.
