Stages of Endometriosis UK

Updated: Oct 21


Stages of Endometriosis UK

If you’ve been diagnosed with endometriosis or are trying to learn more about it, you might be feeling a little overwhelmed. Endometriosis is divided into four stages, ranging from minimal to severe, much like steps on a ladder.


Each stage reflects how far the condition has progressed, and understanding this can help you make sense of your symptoms and treatment options.


Think of endometriosis as similar to weeds in a garden. Normally, the lining of the uterus stays where it belongs, but in endometriosis, that tissue starts growing outside the uterus, like weeds spreading into areas they shouldn’t be. The stages of endometriosis show how widespread these "weeds" have become and how much they are affecting your body.

The stage of endometriosis you have can play a pivotal role in deciding what the best treatment options are such as robotic or laparoscopic surgery, hysterectomy or whether the condition can be managed with medications such as HRT..


Stage 1: Minimal


In stage 1, endometriosis is in its early stages. There may be small patches of tissue growing outside the uterus, but they’re usually shallow and not causing much disruption. You might feel mild discomfort, often mistaken for regular menstrual pain, or you might not notice it at all. At this stage, you might wonder if what you’re feeling is endometriosis, but it’s common for symptoms to be minimal or even absent in the early phase [1].


Stage 2: Mild


Stage 2 is classified as mild and indicates the endometrial tissue has spread a little more and gone a little deeper. You might have more noticeable pain or discomfort around your period, and some scar tissue, known as adhesions, may begin to form. It’s like the weeds growing deeper roots, becoming a bit harder to ignore. At this stage, you may find that your symptoms are becoming more frequent or bothersome, and treatment options may start to play a bigger role in managing your condition.


Stage 3: Moderate


Stage 3 involves more extensive tissue growth and adhesions, which can begin to affect other organs. Pain can become more frequent and severe, but it’s important to know that this stage requires specialist care, and options are available to help manage it.


Stage 4: Severe


In stage 4, endometriosis has become more widespread and deeply invasive. This stage may involve significant pain and complications such as infertility. Though less common, this stage often requires advanced treatments from specialists to help manage symptoms and maintain quality of life.



Stage 1 endometriosis: early symptoms and general care options


Stage 1 endometriosis is like having a few small weeds. it’s there, but it’s not causing too much disruption just yet. However, if you’ve been diagnosed or suspect you have it, it’s natural to have questions about what’s happening inside your body and what you can do about it.


Common symptoms of stage 1 endometriosis


At this stage, symptoms can be subtle or even non-existent, making it easy to overlook or mistake them for regular menstrual cramps. You might experience:


  • Mild pelvic pain, especially around your period

  • Discomfort during or after sex

  • Occasional bloating or discomfort


Think of it as your body sending a soft signal that something’s not quite right. For some, this signal is barely noticeable, while others may feel like something is off but aren’t sure what it is. It’s important to listen to your body and pay attention to these early signs, even if they seem mild.


Diagnosing stage 1 endometriosis


Getting a diagnosis for stage 1 endometriosis can sometimes feel like solving a mystery. Because the symptoms are often mild, doctors may first rule out other causes before identifying endometriosis. The most accurate way to diagnose it is through MRI or laparoscopy- a minor surgical procedure where a small camera is used to look for endometrial tissue.


If you're experiencing symptoms and seeking answers, don’t hesitate to speak with your GP. They can guide you through the process and discuss the best next steps, whether it’s getting referred to a specialist or managing your symptoms in the meantime.


General treatment options for Stage 1 (NHS and private)


The good news is that stage 1 endometriosis can often be managed effectively with treatments available through both the NHS and private care. Common options include:


  • Pain relief: Over-the-counter painkillers, like ibuprofen, can help ease discomfort [2].

  • Hormonal treatments: Options like the contraceptive pill or hormonal IUDs can help control symptoms by reducing or stopping menstruation, helping turn down the volume on the symptoms [3].

  • Laparoscopic surgery: In some cases, if symptoms persist, a minor surgery might be recommended to remove the endometrial tissue. The BSGE highlights that laparoscopy is the gold standard for diagnosis and treatment [4].


It might be helpful to think of these treatments as tools in your toolkit, helping to manage symptoms and prevent the condition from becoming more problematic. The best option depends on your personal preferences, symptoms, and overall health.


Finding the right treatment option for stage 1 endometriosis


The best treatment option for stage 1 endometriosis is not a one-size-fits-all solution. It depends on several factors, including your personal preferences, how the condition affects your daily life, and your overall health. Here’s why:


  • Personal preferences: Some treatments, such as hormonal birth control, might not align with your personal preferences. For instance, if you’re planning to start a family soon, you may not want a treatment that affects your fertility. On the other hand, if you're not concerned about fertility at the moment, hormonal treatments that stop or reduce menstruation might be appealing. Similarly, if you prefer to avoid medication and would rather explore lifestyle changes or natural remedies first, that can guide the treatment you pursue.


  • Symptoms: Endometriosis affects everyone differently. You might experience mild discomfort that’s easily managed with pain relief, or your symptoms might be more disruptive and require stronger interventions like hormonal therapies. The intensity and frequency of your symptoms play a huge role in determining what treatment will offer you the most relief. For example, someone with minimal symptoms might prefer non-invasive treatments like painkillers, while someone experiencing more significant pain might opt for hormonal treatments or surgery to address the root cause.


  • Overall health: Your general health can also influence treatment choices. If you have underlying health conditions or are sensitive to certain medications, this might limit your options. For instance, if you have a history of blood clots, your doctor might recommend avoiding certain hormonal treatments that carry a higher risk of clotting. Additionally, if you have other conditions, such as irritable bowel syndrome (IBS), your treatment plan may need to be tailored to avoid worsening those symptoms.


In essence, your doctor will work with you to find a treatment plan that fits your specific needs and lifestyle. It’s about balancing effective symptom relief with what feels right for you physically and emotionally. Just like choosing the right tool for a job, the best approach is one that fits both your current health and long-term goals.


Prognosis for stage 1 endometriosis


The prognosis for stage 1 endometriosis is generally positive. With the right treatment and care, many people find that their symptoms improve or become more manageable over time. It’s like catching that small spark early before it has a chance to grow into something more disruptive. Regular check-ups and communication with your healthcare provider can ensure you stay on top of your condition and live your life with minimal interruption.



Stage 2 endometriosis


As endometriosis progresses into stage 2, the condition becomes a bit more noticeable, but it’s still manageable. If we go back to the garden analogy, the weeds have spread a little further, but they haven’t yet taken over. With the right care, you can still keep things under control. At this stage, it’s common to experience more frequent or bothersome symptoms, but treatment options remain effective.


Symptoms of stage 2 endometriosis


In stage 2, the symptoms can start to make more of an impact on your daily life, though they’re still considered mild. You might notice:


  • Pelvic pain that’s more consistent, especially during menstruation.

  • Pain during or after sex.

  • Bloating, sometimes referred to as "endo belly."

  • Slight discomfort during bowel movements or urination.


The symptoms might feel more noticeable, but this doesn’t mean they’re out of control. At this stage, it’s important to start paying closer attention to how your body feels and consider treatment options that will prevent the condition from progressing further.


Diagnosis and general treatment options for stage 2


Diagnosing stage 2 endometriosis follows a similar path to stage 1, but because symptoms may be more pronounced, it can be easier for doctors to recognise and diagnose. If you’ve been experiencing more regular pain, your GP might recommend an ultrasound to rule out other causes before considering a laparoscopy, which remains the gold standard for diagnosing endometriosis.


As for treatment, there are a few options available through both the NHS and private healthcare providers:


  • Pain relief: Over-the-counter painkillers like ibuprofen or prescription options can help manage discomfort.

  • Hormonal treatments: Birth control pills, hormonal IUDs, or other hormonal therapies can help reduce or stop menstruation, thereby easing symptoms and delaying the condition’s progress.

  • Laparoscopic surgery: If symptoms are more persistent, surgery might be recommended to remove the endometrial tissue. This can help relieve pain and improve quality of life.


Much like tending to a garden, regular treatment at this stage can prevent the "weeds" from spreading, keeping symptoms under control and allowing you to get on with your life.


When to consider specialist referral for stage 2


While stage 2 can often be managed with these general treatments, there are times when a referral to a specialist is the best course of action. If your symptoms are becoming more intense despite treatment, or if you’re experiencing fertility issues, a specialist can provide more targeted care. This might involve advanced imaging or more in-depth surgical options that can address deeper or more widespread endometriosis tissue. They can offer more focused advice and treatments that go beyond the general care options.


Prognosis for stage 2 endometriosis


The prognosis for stage 2 endometriosis remains positive, especially when treatment is started early. Timely treatment can make a world of difference in preventing the condition from advancing further and minimising the impact on your daily life. The sooner you take action, the easier it is to manage your symptoms and maintain control [5].


Acting quickly not only reduces pain but can also help preserve fertility and improve overall quality of life [6]. Early intervention often means simpler treatments are more effective, which can save you from needing more invasive options later on. For example, if hormonal treatments are started early, they can help stop the condition in its tracks before it progresses to more severe stages that require surgery [7].


Private treatment options for stage 2 endometriosis


If you’re considering private treatment, it can be a really worthwhile investment in your health and recovery. Private healthcare often provides:


  • Quicker access to specialists: Private treatment can reduce waiting times, meaning you can start managing your symptoms sooner and avoid the frustration of waiting for referrals.

  • More personalised care: Private treatment often means longer consultations and more time to discuss your symptoms and concerns, allowing for a tailored approach that fits your unique situation.

  • Access to advanced treatments: Some private clinics offer the latest surgical techniques or less invasive procedures that might not be as readily available in the NHS.


Investing in private treatment can feel like giving your health the attention it deserves, ensuring you get the right care at the right time. Whether you choose NHS or private care, the key takeaway is that addressing stage 2 endometriosis early can set you up for a smoother journey ahead, giving you the best chance of managing symptoms and preventing progression.



Advanced stages of endometriosis: stage 3 and stage 4 overview


When endometriosis progresses to stages 3 and 4, it becomes more complex, and the symptoms can have a greater impact on your daily life. However, it’s important to remember that even in these more advanced stages, treatment options and specialist care are available to help manage symptoms and improve quality of life.


Symptoms of stage 3 endometriosis


Stage 3 endometriosis is often referred to as “moderate” endometriosis. At this point, the condition is more widespread, and adhesions (scar tissue) can begin to bind organs together. The symptoms may include:


  • Chronic pelvic pain that can be persistent, not just around menstruation.

  • Painful periods that interfere with daily activities.

  • Pain during or after sex, which may worsen.

  • Increased bloating and discomfort.

  • Possible fertility issues, as stage 3 endometriosis may begin to affect reproductive organs more significantly.


If you’ve noticed your symptoms becoming more severe or consistent, it’s possible that stage 3 endometriosis is the cause. At this stage, it’s often best to consult a specialist for more advanced care options.


Treatment options for stage 3 (private and NHS)


Managing stage 3 endometriosis often requires a more targeted approach. Both private and NHS treatment options are available to help control symptoms and slow the progression of the condition:


  • Hormonal treatments: These continue to be an option, especially for those not looking to conceive. Hormonal therapies can reduce the amount of endometrial tissue that forms each month.

  • Laparoscopic surgery: For stage 3, surgery to remove the endometrial tissue may be recommended. This can help relieve pain and improve fertility. Private treatment can offer faster access to this type of surgery, with more flexibility in choosing your surgeon.

  • Fertility treatments: If fertility is a concern, both private and NHS fertility specialists can assist. IVF is often an option for women with stage 3 endometriosis who are struggling to conceive naturally.


The combination of treatments will depend on your symptoms and overall health, but the key is to find an approach that helps you manage pain and prevent further damage.


Stage 3 endometriosis may require specialised care, sometimes this may include more complex surgeries or fertility treatments. Private care may provide quicker access to specialists who can offer advanced surgical options.


Stage 4 endometriosis: severe symptoms and specialist care


Stage 4 endometriosis is the most advanced form of the condition, often involving deep implants and severe adhesions, which can even bind organs like the bladder or bowel to the uterus or ovaries. Symptoms may include:


  • Intense, chronic pelvic pain.

  • Pain that extends to the lower back or legs.

  • Difficulty with bowel movements or urination, as endometrial tissue may impact these organs.

  • Severe bloating and digestive issues.

  • Infertility, which can become more pronounced as the condition affects reproductive organs.


As with stage 3 endometriosis, stage 4 endometriosis typically requires specialised care, which can include more complex surgeries or fertility treatments. As mentioned previously private care options may provide quicker access to specialists who can offer advanced surgical options.


Referral to specialists for advanced endometriosis


For stages 3 and 4, getting a referral to a specialist is often essential. Specialists in endometriosis can provide more advanced diagnostic tools, such as MRI scans, and offer treatments that go beyond what is available through general care. Private treatment can reduce the waiting time for these referrals, allowing you to begin more intensive treatment sooner.


Prognosis for stage 3 and stage 4 endometriosis


While stages 3 and 4 endometriosis can be challenging to manage, timely treatment and specialist care can still make a significant difference. Surgery often provides relief from pain and improves fertility for many women [8]. With ongoing management, many people are able to maintain a good quality of life, even at these more advanced stages [9].


The earlier you receive specialist care, the better your chances of preventing further complications. Opting for private treatment can offer faster access to surgeries and fertility treatments, potentially improving your long-term outlook [10]. With the right care, living well with advanced endometriosis is still very possible.
