Endometriosis
Endometriosis isn’t one disease — it’s many.
Diversity in immune responses, hormone receptor expression, and transcriptomic profiles all suggest that endometriosis manifests uniquely in each individual, requiring personalized diagnostic and therapeutic approaches.
One Size Does Not Fit All
Understanding Endometriosis
The Lotus Endometriosis Institute takes a unique stance on endometriosis that you are unlikely to find elsewhere. Recent molecular and genomic research strongly supports the notion that endometriosis is not a single disease entity, but a heterogeneous condition composed of distinct subtypes. Each of these subtypes have potentially different origins, clinical behavior, and treatment responses. Some of it is genetic, some of it you can influence, and some you cannot.
What is it?
Endometriosis is a condition where cells similar to the uterine lining (endometrium) grow outside the uterus, potentially into the pelvis or abdomen. The condition has varying severities and symptoms.
When can it happen?
Endometriosis can occur at any age. It can be found in your teens, early childhood, or even earlier in-utero as a fetus. The condition primarily affects middle aged women, but can also be post-menopausal.
Why does it occur?
The exact causes are not currently known, and they likely differ from person to person. Contributors possibly include embryologic müllerianosis, genetics & epigenetics, molecular translational changes, pelvic tissue transformation called metaplasia and more. It is most definitely "multi-factorial" and "polygenic".
Where can it spread?
Endometriosis can affect not only your pelvic organs and delicate structures, which include your bladder, ureters and rectum, but also outside your pelvis higher up in the abdomen. There it can involve your intestines. Endometriosis can spread literally anywhere in your body, including the lungs (metastatic) and beyond.
Common Issues
Symptoms
Endometriosis often presents with symptoms that can vary greatly in severity and impact, making it challenging to recognize early. While some people experience debilitating pain, others may have subtle signs that are easily overlooked or mistaken for common menstrual issues. Understanding the range of potential symptoms is the first step toward earlier diagnosis and effective treatment.
Pelvic / Abdominal Pain
Persistent or cyclical pain in the pelvis and lower abdomen is one of the most common symptoms, often worsening around menstruation but not limited to it.
Bloating
Abdominal bloating, sometimes called “endo belly,” can appear suddenly, feel severe, and fluctuate day to day.
Painful Sex
Discomfort or sharp pain during or after intercourse is common, often tied to inflammation, scarring, or adhesions.
Infertility
Endometriosis can interfere with fertility by affecting the ovaries, fallopian tubes, or pelvic environment, though many with the condition do conceive with treatment.
Urinary Frequency
Some experience urgency or frequent urination, particularly if lesions involve the bladder.
Painful Bowel Movements
Bowel movements may trigger cramping or sharp pain, especially during menstrual cycles.
Back and Leg Pain
Pain can radiate into the lower back, hips, or legs, reflecting how endometriosis affects surrounding nerves and tissues.
And Far More
Symptoms extend well beyond this list, with wide-ranging effects on the body and quality of life—making awareness and individualized evaluation essential.

Different for Everyone
Subtypes & Stages
The ASRM (American Society for Reproductive Medicine), defines four stages of endometriosis. The stages are not necessarily proportional to pain or symptoms. Some patients exhibit less pain than others, even if they have a higher stage diagnosis. Additionally, the condition can be described by different "subtypes" including: superficial endometriosis (on peritoneal surface), deep infiltrating endometriosis (invading tissues), ovarian endometriomas ("chocolate cysts"), metastatic endometriosis (spread to distant areas), and malignant degeneration (rare but life-threatening).
Stage 1 - Minimal
There are small patches or implants either on or around the organs in the pelvis.
Stage 2 - Mild
Increasing number of implants but damage to the pelvic organs is still minimal with not much scarring or adhesions. Altogether, the implants are not more than ~5cm.
Stage 3 - Moderate
Implants are more widespread and are beginning to infiltrate the organs in the pelvic region, including pelvic side walls, ureters, and peritoneum. There is more scarring and adhesions and endometriomas (“chocolate cyts”) on the ovary.
Stage 4 - Severe
The disease is infiltrating and affecting several organs (e.g. bladder, rectum) in the pelvic region, as well as the ovaries. Anatomy is severely distorted with scars and adhesions, with fibrosis (like concrete) between organs. Larger and more endometriomas can be seen.
Insights for Your Health
Prevention and Detection
While the near future may bring molecular genetic insights into targeted prevention, today there is no reliable way to prevent endometriosis. In fact, there is a genetic predisposition which is not well understood. If you have a relative with endometriosis, you have a 5-7x risk of being affected. What those genetic switches are will be uncovered soon and prevention and treatment will be enhanced. Meanwhile, you can do a lot towards reducing the chances it will affect you and maybe decrease endometriosis progression. We provide integrative insights into endometriosis-reducing lifestyle-modifications, and they are as natural a strategy for endometriosis treatment as it gets.
Excision Surgery Leads the Way
Surgical Treatment
Surgery plays a central role in endometriosis care, serving as both a diagnostic tool and today’s gold-standard for initial treatment of pain relief, infertility, and suspicious masses. Because endometriosis can vary depending on where it is located—inside or outside the pelvis—and what stage it has reached, treatment must be carefully tailored to each individual. Minimally invasive excision surgery offers accurate diagnosis while providing effective symptom relief, but it should be strategically timed, as repeated procedures can increase scar tissue and risk. For the best outcomes, the benefits must always outweigh the risks, making timing and the expertise of the surgeon essential to every decision.
Common Questions
When is menstrual bleeding considered too heavy?
Menstrual flow is generally “too heavy” when it consistently disrupts your life or overwhelms your usual period products—think flooding or soaking through pads/tampons quickly, passing frequent or large clots, needing to double up, or bleeding long enough that you can’t plan around it. Another major clue is fatigue, dizziness, or shortness of breath that can come with iron deficiency from ongoing blood loss. If you’re timing your day around bathrooms, waking at night to change products, or avoiding work, exercise, travel, or sex because of bleeding, that’s not something we consider “normal.”
Heavy bleeding is a symptom, not a diagnosis, and common underlying drivers include adenomyosis, fibroids, hormonal imbalance, and sometimes endometriosis—especially when heavy bleeding shows up with severe cramps or deep pelvic pain. Because imaging and symptoms don’t always match (a scan can look “mild” while symptoms are intense), we take a symptom-led approach and look at the full pattern, including pain, pressure, clots, cycle timing, and any signs of anemia. If your bleeding feels like it’s escalating or you’ve been told to “just live with it,” our team can help you sort out likely causes and build a plan that targets the source—not just the bleeding.
Can endometriosis cause arthritis-like joint pain?
Yes—endometriosis can be associated with arthritis-like joint pain in some people, even though joint pain isn’t considered a classic “core” symptom. Endometriosis can drive chronic inflammation and immune dysregulation, and that whole-body inflammatory state may show up as aching, stiffness, or flares that feel similar to inflammatory arthritis. Some patients also notice joint symptoms that cycle with their period or worsen during broader endometriosis flares.
At the same time, endometriosis doesn’t “equal” autoimmune arthritis, and an association doesn’t prove that one causes the other. Research suggests higher rates of certain autoimmune conditions in people with endometriosis—including inflammatory diseases that can affect joints—so persistent joint pain deserves a full-picture evaluation rather than being automatically attributed to pelvic disease alone. If you’re dealing with pelvic pain plus joint symptoms, our team can help you sort out what fits endometriosis, what may be a related immune condition, and how that affects your treatment plan, including whether excision surgery and coordinated integrative support make sense for you.
How does estrogen affect the endometrium?
Estrogen is one of the main hormones that drives endometrial growth. In the first half of the menstrual cycle, rising estrogen signals the endometrium to thicken and rebuild after a period, preparing the uterus for a possible pregnancy. It also influences the local immune and inflammatory environment in the uterus, which is part of why hormonal shifts can change bleeding patterns and pain.
When estrogen’s growth signals are strong—and progesterone’s “calming” effect is weaker than expected (often described as progesterone resistance)—the endometrium can behave in a more persistently inflamed, reactive way. This hormone–inflammation pattern is especially relevant in estrogen-dependent conditions like adenomyosis and endometriosis, where tissue similar to the endometrium can contribute to ongoing symptoms. If you’re trying to make sense of heavy bleeding, severe cramping, or cycle-linked pelvic pain, our team can help you connect the hormonal biology to what you’re feeling and review next steps for diagnosis and treatment.
How long do endometriosis flare-ups last?
Endometriosis flare-ups don’t have one “usual” length—some people feel a spike in symptoms for a few hours to a couple of days, while others have flares that stretch across an entire cycle window or blend into more constant pain. Many flares track with hormonal shifts (often before and during a period), but bowel, bladder, pelvic floor, or nerve-related pain can flare at different times and may not follow a neat calendar pattern.
When flares start lasting longer or happening more often, it can be a sign that multiple pain drivers are stacking—ongoing inflammation from lesions, adhesions/fibrosis that can “tether” organs, and sometimes central sensitization, where the nervous system becomes more reactive over time. That’s why symptom management alone can feel like a band-aid if active disease is still present. If you’re noticing prolonged, unpredictable, or escalating flares, our team can help you map your pattern, identify what’s likely driving it, and discuss a plan that addresses both symptom control and the underlying endometriosis.
How long does endo belly (bloating) usually last?
“Endo belly” can last anywhere from a few hours to several days, and for some people it can linger longer or feel nearly constant during certain parts of the month. The duration often depends on what’s driving it for you—hormone-linked inflammation around ovulation or a period, bowel slowing/constipation, pelvic adhesions restricting organ movement, or a combination. Many patients notice it waxes and wanes, sometimes changing noticeably within the same day.
If your bloating is predictable and cyclical, that pattern can be a clue that endometriosis or adenomyosis-related inflammation is playing a major role—even when imaging looks “normal.” If it’s frequent, severe, or paired with bowel or bladder symptoms (pain with bowel movements, urinary urgency, rectal pressure), it can also suggest deeper pelvic disease or significant inflammation affecting nearby organs. Our team can help you sort out whether your “endo belly” is primarily hormonal, GI-driven, or related to pelvic disease that may benefit from targeted treatment, including excision when appropriate—reach out to schedule a consultation and we’ll map your symptoms to a clear plan.
What do endometriosis blood clots look like?
Endometriosis itself doesn’t create a specific, recognizable “type” of blood clot you can identify just by looking. The clots you pass during a period are usually clotted menstrual blood mixed with pieces of shed uterine lining, so they can look dark red to deep brown, jelly-like, stringy, or like thicker “chunks”—and this can happen with or without endometriosis.
What matters more than appearance is the pattern that comes with it. If you’re seeing clots along with heavy or abnormal bleeding, severe or worsening period pain, pain with sex, bowel or bladder symptoms, or pelvic pain that isn’t limited to bleeding days, that combination can fit with endometriosis (and can also overlap with other conditions like adenomyosis or fibroids). If this is what you’re experiencing, our team can help you sort out the likely drivers and discuss what a thorough evaluation and long-term treatment plan can look like—including when minimally invasive excision surgery is worth considering.
