Related Conditions
It’s not always just endometriosis.
Many conditions mimic, worsen, or coexist with endometriosis. Endo can produce a lot of seemingly unrelated symptoms, but most likely it does not produce every symptom you may have.
Looking Closely
We consider every possibility
Every piece matters, which is why our diagnostic and care plan addresses the whole picture—not just the obvious. This ensures a more complete solution and enables you to thrive going forward.
Gastrointestinal & Immune-Related
Gut dysbiosis (SIBO, leaky gut)
Digestive issues and so-called Endo-Belly bloating are very common in patients with endometriosis, but not all are caused directly by the disease itself. Small Intestinal Bacterial Overgrowth (SIBO) and “leaky gut” can create bloating, abdominal pain, diarrhea, or constipation that overlap with endo symptoms. Chronic inflammation from gut dysbiosis can also worsen pelvic pain and fatigue. By identifying and treating underlying gut imbalances, symptoms often improve and whole-body health is supported.
Mastocytosis & MCAS
Mast cell activation plays a role in inflammation and pain signaling. Some patients with endometriosis also have acute or chronic Mast Cell Activation Syndrome (MCAS) or mastocytosis, which can intensify pain, fatigue, and allergic-type symptoms. This immune system overactivity can make endo symptoms feel worse and harder to control. Recognizing and calming mast cell activity can be a key part of improving overall well-being.
Autoimmune conditions
Endometriosis is not primarily an autoimmune disease itself, but it shares features with autoimmunity — including chronic inflammation and immune dysregulation. Many patients with endo are also diagnosed with conditions like thyroid disease, lupus, or rheumatoid arthritis. These overlapping illnesses can complicate symptoms and require coordinated care. By screening for autoimmune conditions, we can build a plan that addresses the bigger picture.
Chronic Infections (Lyme & Coinfections)
Some patients with endometriosis also carry chronic infections such as Lyme disease or related bacterial or mold coinfections. These can create widespread pain, fatigue, and neurological symptoms that overlap with or intensify endo symptoms. Both conditions involve immune dysregulation and chronic inflammation, making them difficult to distinguish without careful testing. Addressing underlying infections can reduce total body inflammation and make endometriosis care more effective.
Mold & Environmental Illness
Exposure to mold toxins (mycotoxins) can trigger a wide range of symptoms: fatigue, brain fog, pelvic pain, bladder irritation, and more. For endometriosis patients, mold-related illness may worsen immune imbalance and heighten inflammatory flares. Because symptoms are nonspecific, mold illness is often overlooked or dismissed, leading to years of suffering. Identifying and treating mold exposure can play a key role in reducing overall symptom burden and supporting recovery.
Vascular & Structural
Pelvic venous congestion
Pelvic venous congestion is a condition where enlarged, varicose-like dilated veins in the pelvis cause chronic pain. The pain can feel very similar to endometriosis—worsening with standing, at the end of the day, or after sexual activity. Some patients may even be misdiagnosed with endo when pelvic vein issues are the main driver. Careful imaging and evaluation help distinguish the two and guide treatment. Combined imaging as well as surgical findings can help determine if this is part of overall pelvic pain causation.
May-Thurner Syndrome
May-Thurner Syndrome is a vascular condition where a large pelvic vein is compressed, leading to leg heaviness, swelling, or pelvic discomfort. Its symptoms can mimic or compound endometriosis-related pain. Because it’s not widely recognized, many patients go years without diagnosis. Screening for this condition using imaging ensures that vascular causes of pain are not overlooked.
Hernias
Groin or abdominal wall hernias may present with pelvic or lower abdominal pain that overlaps with endometriosis symptoms. Sometimes, endometriosis itself is found inside or around a hernia sac. Because hernia pain can mimic deep endo pain, it’s important to evaluate carefully. Repairing a hernia in the right setting can significantly reduce pain and improve quality of life. Repair may or may not be recommended at the time of endo excision because it often requires placement of a synthetic mesh which has its own risk vs benefit considerations.
Pelvic Mass Cancer Risk
Pelvic masses are often benign, but sometimes endometriosis is mistaken for a tumor, or vice versa. Endometriosis can also rarely transform into certain types of ovarian cancer, especially clear cell or endometrioid types. It’s important not to miss these possibilities in evaluation. For that reason, we use careful imaging and, when necessary, surgical assessment to distinguish between benign disease and malignancy. This is more often an issue in older patients but can occur when younger, especially if there is a family history of cancer or genetic abnormalities are found.
Adhesions (Post-Surgical Scarring) and Fibrosis
Many patients with endometriosis have a history of multiple surgeries, which can result in adhesions — internal scar tissue that binds organs together. Adhesions and fibrosis can also occur as your body tries to clear endometriosis lesions. These adhesions and fibrosis can cause pain, bowel obstruction, and infertility, often mimicking recurrent endometriosis. Differentiating adhesion pain from true disease recurrence is crucial in planning further treatment. Specialized surgical techniques and the highest level surgeon are often required to safely release adhesions, especially in extremely distorted scarred fibrotic anatomy. Part of the problem is that there is no way to predict how much scarring or fibrosis may be found. After surgery has started is not the time to start looking for a surgeon or assistant/consultant that can handle the hardest cases.
Neurological, Pain, & Sensitization
Pelvic floor dyssynergia
Both endometriosis and adenomyosis are inflammatory conditions. The nearby pelvic floor muscles can tighten or spasm in response to this, creating another reason for pain. Over time, this leads to pelvic floor dyssynergia — where the muscles fail to relax properly during bowel movements or intercourse. The result is constipation, pain, and worsening pelvic tension. Pelvic floor physical therapy is a critical part of finding and working with pelvic floor trigger points.
Small Fiber Neuropathy & Central Sensitization
Chronic pelvic pain can sometimes be driven not only by inflammatory endo lesions triggering nerve endings on the peritoneum (peripheral sensitization), but by nerve hypersensitivity or small fiber neuropathy (nerves themselves are damaged). Patients may also experience burning, tingling, or widespread pain that continues even after surgery. This represents central sensitization — when the nervous system becomes “stuck in pain mode.” Managing neuropathic pain is essential to restoring function and quality of life.
Fibromyalgia & Chronic Fatigue Syndrome (ME/CFS)
Some endometriosis patients develop fibromyalgia or ME/CFS, both characterized by widespread pain and profound fatigue. These syndromes reflect immune and mitochondrial dysfunction, which can make endometriosis symptoms more debilitating. Without recognition, patients may undergo unnecessary repeat surgeries when systemic support is what’s needed most. Integrating care for these conditions can dramatically improve daily function.
Connective Tissue & Autonomic Disorders
Ehlers–Danlos Syndrome (EDS) & Hypermobility
Ehlers–Danlos and related hypermobility disorders affect connective tissue strength and elasticity. Many patients experience pelvic pain, bowel dysfunction, and organ prolapse that mimic or compound endometriosis symptoms. Because connective tissue is more fragile, surgery and recovery can be more complex. EDS frequently overlaps with mast cell disorders and autonomic issues, creating a cluster of conditions that amplify pain and fatigue. Some forms of EDS diagnosis are clinical and some are genetic and it’s critical to know the difference to minimize your risks.
Postural Orthostatic Tachycardia Syndrome (POTS) & Dysautonomia
Dysautonomia is an autonomic nervous system dysfunction, often showing up as POTS — dizziness, rapid heartbeat, and fatigue when standing. These symptoms can be mistaken for anxiety or dismissed as unrelated, but they often coexist with endometriosis. Autonomic imbalance can intensify pain flares and make recovery after surgery more difficult. Recognizing this overlap is important to provide whole-person care and symptom relief.
Bladder & Pelvic Syndromes
Interstitial Cystitis / Bladder Pain Syndrome
Bladder pain syndrome is extremely common in endometriosis patients, yet often missed. It causes urinary frequency, urgency, and pelvic pain that overlap with endo symptoms, making diagnosis challenging. In some cases this is purely because there is a lot of endo growing on or into the bladder. But even after successful excision surgery, bladder pain can persist. This may mean IC is part of the problem. Tailored bladder-directed therapies are often required for complete relief.
Endocrine & Hormonal
Endocrine Disorders (Thyroid, PCOS, Adrenal Dysfunction)
Hormonal imbalances are common in endometriosis patients, particularly thyroid disorders and overlapping polycystic ovary syndrome (PCOS). These conditions contribute to fatigue, irregular cycles, and fertility challenges. Chronic stress and adrenal dysfunction further amplify pain and inflammatory pathways. Screening for endocrine overlap allows for more precise and comprehensive treatment planning without tunnel vision focusing blindly on endo itself.

Common Questions
How is diaphragmatic endometriosis diagnosed?
Diaphragmatic endometriosis can be difficult to confirm because symptoms may be subtle (or absent) and imaging doesn’t always “see” superficial implants. We start with your full symptom story and patterning—especially cyclical right upper abdominal, rib, chest, shoulder, or arm pain that flares around your period or with deep breaths/coughing—then pair that with a targeted exam and a careful review of prior workups so we don’t miss look-alike or coexisting conditions.
Imaging such as MRI (and sometimes CT, depending on the situation) can help raise suspicion, map anatomy, and guide surgical planning, but a normal scan does not rule it out. The most reliable way to diagnose diaphragmatic endometriosis is minimally invasive surgery (laparoscopy or robotic surgery) with deliberate inspection of the diaphragm and confirmation by removing suspicious lesions for pathology when appropriate.
If symptoms suggest disease may extend into the chest (thoracic endometriosis), diagnosis may require coordination with a thoracic surgeon and, in select cases, a chest procedure such as VATS in addition to laparoscopy. Our team plans this proactively when your history or imaging points in that direction, so you’re not left with an incomplete evaluation or a surgery that isn’t equipped to address the full extent of disease.
Endometriosis or herniated disc—how can I tell?
Endometriosis pain often has a pelvic “rhythm”—it flares with your cycle, deepens around periods, and may come with symptoms like pain with sex, bowel movements, or urination, bloating, or a heavy pelvic ache. A herniated disc more commonly behaves like a spine/nerve problem: low back pain that travels into the buttock/leg, burning or tingling, or pain that changes with posture (sitting, bending, coughing) rather than with bleeding or ovulation. That said, endometriosis can irritate pelvic nerves and mimic sciatica, and it’s also common for endometriosis and a true disc issue to coexist.
The most reliable way to sort this out is a careful pattern-based history plus a targeted exam, then the right imaging interpreted with your symptoms in mind—sometimes pelvic MRI/ultrasound to look for pelvic disease, and sometimes spine imaging if the story fits. Our team focuses on distinguishing endometriosis from look-alikes (and finding coexisting drivers like pelvic floor dysfunction or hernias) so you’re not stuck treating the wrong problem. If you’re dealing with overlapping pelvic and back/leg pain, reach out to schedule an evaluation—bringing a symptom timeline (cycle days, triggers, radiation of pain, numbness/weakness) can make your visit far more actionable.
Can adenomyosis cause headaches or migraines?
Yes—adenomyosis can be associated with headaches or migraines for some patients, especially when symptoms flare around the menstrual cycle. Adenomyosis is hormonally responsive and can drive inflammation and pain signaling in the body, and that whole-body inflammatory “load” can overlap with migraine biology in susceptible people.
That said, headaches aren’t considered a classic hallmark symptom the way heavy bleeding, severe cramping, and an enlarged/tender uterus are. When headaches are prominent, we also look at common overlap scenarios—like adenomyosis coexisting with endometriosis—and whether the timing tracks with bleeding, cramping, or hormonal shifts.
If your headaches reliably worsen with your cycle or improve when pelvic symptoms are better controlled, that pattern can be an important clue. Our team can help you connect the dots between uterine disease, cycle patterns, and your broader symptom picture, and then discuss treatment pathways that fit your goals—whether that’s targeted medical therapy, minimally invasive surgery when appropriate, and supportive strategies that are coordinated as part of one plan.
Can adenomyosis cause vulvar pain?
Adenomyosis is confined to the uterus (endometrial-like tissue within the uterine muscle), so it doesn’t directly “spread” to the vulva. However, it can still contribute to vulvar pain indirectly by driving pelvic inflammation, cramping, and a sensitized pain system that can amplify pain signals and trigger pelvic floor muscle guarding.
Just as importantly, vulvar pain often has its own contributors that can coexist with adenomyosis—like endometriosis elsewhere in the pelvis, bladder pain syndromes, or pelvic floor/myofascial pain that refers discomfort to the vulvar area. When we evaluate vulvar pain in someone with suspected or known adenomyosis, we focus on the full pattern (timing with cycles, deep pelvic pressure vs surface burning, urinary or bowel symptoms, pain with sex) so we don’t miss a “neighbor” condition that needs its own targeted plan.
If vulvar pain is a prominent symptom for you, our team can help you sort out whether it’s primarily uterus-driven, referred/neuromuscular, or a separate overlapping diagnosis—because that distinction often changes what treatments are most likely to help.
Can adenomyosis cause clots and heavy flooding?
Yes. Adenomyosis can cause very heavy menstrual bleeding, and that can show up as “flooding” (sudden gushes) and passing clots—especially when bleeding is fast enough that blood pools in the uterus and forms clots before it exits. Because adenomyosis involves endometrial-like tissue within the uterine muscle, it can drive stronger, more painful uterine contractions and more persistent bleeding during a cycle.
That said, clots and flooding aren’t specific to adenomyosis. Fibroids, polyps, hormonal bleeding patterns, bleeding disorders, and adenomyosis overlapping with endometriosis can look similar—and severe bleeding can quickly lead to iron deficiency and fatigue even if your labs were “normal” in the past. If this is happening to you, our team can help you make sense of your symptom pattern and imaging (often ultrasound and sometimes MRI) and walk you through options aimed at bleeding control and long-term relief, including uterine-preserving approaches when appropriate.
Why am I passing large blood clots during my period?
Passing large clots during your period usually means the bleeding is heavy enough that blood is pooling in the uterus and clotting before it exits. Some clotting can be normal, but frequent or large clots—especially when paired with flooding, severe cramps, pelvic pressure, or fatigue—can be a sign that something is driving abnormally heavy uterine bleeding rather than “just a bad period.”
Two common underlying causes we evaluate for are adenomyosis (endometrial-like tissue within the uterine muscle, often linked with heavy bleeding and painful periods) and fibroids, and it’s also possible for adenomyosis to overlap with endometriosis and intensify symptoms. Because the right treatment depends on the cause, our team focuses on your full symptom pattern and uses expertly interpreted ultrasound and, when helpful, MRI to look for adenomyosis and other pelvic conditions that can be missed or mislabeled.
If you’re passing clots larger than a quarter, soaking through protection quickly, feeling lightheaded, or your bleeding is disrupting daily life, it’s worth a deeper workup—not dismissal. You can reach out to schedule a consultation so we can map out what’s most likely in your case and what options (medical, procedural, or surgical) make sense for your goals, including fertility and long-term relief.
