There is no cure for endometriosis. The treatment provided aims to reduce the severity of the symptoms and improve quality of life. The exact treatment offered will depend on the symptoms, patient age, fertility and priority of starting a family.
Broadly speaking, there are two types of treatment; medication and surgery.
If their endometriosis is causing pain, patients will be offered medication to ease this. Drugs such as non-steroidal anti-inflammatories (NSAIDs) and paracetamol may help to ease painful menstrual cramps.
Some patients will be prescribed hormonal therapy to help alleviate their symptoms. The combined oral contraceptive pill and progestin therapies, such as the mirena coil, are used to reduce the buildup of endometrial tissue every month. They do this either by preventing monthly menstruation completely, or by making the menstrual flow a lot lighter and shorter. With fewer endometrial deposits, inflammation will be reduced and patients will experience less pain. Gonadotrophin-releasing hormone (GnRH) analogues and testosterone derivatives both block oestrogen production, essentially putting the body into a state of artificial menopause.
The problem with hormonal treatment is that it will not help to improve fertility, quite the reverse in fact. Most hormonal options cause the body to enter into a state of artificial pregnancy or menopause, thus preventing fertilisation and implantation. Therefore, this treatment is not suitable for those patients who are seeking help to conceive.
The first line of treatment for women experiencing endometriosis-associated infertility is to undergo a laparoscopy, a surgical process where a camera is inserted through the abdomen in order to examine the underlying organs. This is classed as conservative surgery. Used in the first instance for diagnosis, surgeons will attempt to remove accessible endometrial deposits at the same time. This treatment is reasonably effective for patients with mild-moderate endometriosis. The drawback is that there is a high recurrence rate, so symptomatic relief may only be temporary.
It is believed that between 5 and 20% of women with endometriosis will get recurrence of symptoms each year, probably due to further endometrial deposits forming. A year after surgery, 45% of women are likely to report that they are experiencing pain again.
More radical surgery involves removal of the uterus (hysterectomy) and/or ovaries (oophorectomy). Removing the ovaries causes an instant and irreversible menopause and is thus only suitable for women who are not planning on having children.
Optimal treatment strategies for endometriosis will generally incorporate a multidisciplinary approach, with a view to treating both the physical and psychological effects of the condition.

* [PCOS](https://nabtahealth.com/glossary/pcos/) is sometimes treated with metformin, a drug for [insulin resistance](https://nabtahealth.com/glossary/insulin-resistance/). * 60-70% of women with [PCOS](https://nabtahealth.com/glossary/pcos/) are insulin resistant which is why metformin may be prescribed. * Clinical studies exploring metformin and [PCOS](https://nabtahealth.com/glossary/pcos/) symptoms have been small and inconsistent, but there is some evidence metformin increases [ovulation](https://nabtahealth.com/glossary/ovulation/) rate in women with [PCOS](https://nabtahealth.com/glossary/pcos/) when compared to treatment with a placebo. * Other studies have found that there is no consistent evidence that metformin improves the signs of hyperandrogegism (such as hairiness from excess male hormones). * However, metformin should not be completely discounted as an option for the management of [PCOS](https://nabtahealth.com/glossary/pcos/) [Metformin](https://nabtahealth.com/what-is-metformin/) is the first line treatment approach for type 2 diabetes mellitus (T2DM). It works by improving the way in which the body responds to insulin, preventing blood sugar levels from getting too high. Metformin is not licensed for the treatment of [](https://nabtahealth.com/what-is-pcos/)[PCOS](https://nabtahealth.com/glossary/pcos/), but as many women with the condition are [insulin resistant](https://nabtahealth.com/treating-the-associated-symptoms-of-pcos/), it is often prescribed ‘off label’ to help manage the symptoms. This article aims to address some questions regarding the use of metformin in the management of [PCOS](https://nabtahealth.com/glossary/pcos/). Is there justification in its use? Can it help to improve the symptoms of the condition, or are there alternative options that will be more effective? Will there ever be a time when metformin is prescribed as standard for all women with [PCOS](https://nabtahealth.com/glossary/pcos/) and to treat [PCOS](https://nabtahealth.com/glossary/pcos/) side effects? #### **Why metformin and [PCOS](https://nabtahealth.com/glossary/pcos/)?** Metformin is safe and cost effective, hence it’s widespread use in the management of T2DM. [Insulin resistance](https://nabtahealth.com/glossary/insulin-resistance/) is not one of the three diagnostic criteria used in defining [PCOS](https://nabtahealth.com/glossary/pcos/), however it is recognised as a common feature. In fact, 60-70% of women with [PCOS](https://nabtahealth.com/glossary/pcos/) will be insulin resistant and it is thought that the higher than normal levels of insulin contribute to many of the phenotypic traits of the condition. Thus, it makes sense that treating the [insulin resistance](https://nabtahealth.com/glossary/insulin-resistance/) might help to alleviate other [PCOS](https://nabtahealth.com/glossary/pcos/) side effects, for example regulating the menstrual cycle and improving signs of unwanted hair growth and acne. #### **What does the science say about [PCOS](https://nabtahealth.com/glossary/pcos/) and metformin?** Unfortunately metformin has not turned out to be the wonder drug that some anticipated. The clinical studies to date have largely been small in sample size and results have been inconsistent. In 2017, the American Society for Reproductive Medicine published guidelines on the use of metformin for the treatment of [infertility](https://nabtahealth.com/glossary/infertility/) in women with [PCOS](https://nabtahealth.com/glossary/pcos/). They based these guidelines on the results of a comprehensive literature review. The main conclusions reached were: * There is some evidence that metformin increases [ovulation](https://nabtahealth.com/glossary/ovulation/) rate in women with [PCOS](https://nabtahealth.com/glossary/pcos/) when compared to treatment with a placebo. **However:** * Clomiphene citrate is more effective at inducing [ovulation](https://nabtahealth.com/glossary/ovulation/) than metformin. * Metformin plus clomiphene citrate is more effective than metformin alone. * There is insufficient data on pregnancy and live birth rates following metformin treatment. Thus, the longer term overall reproductive benefit cannot currently be established. **Furthermore:** * There is insufficient evidence to recommend metformin as an option to [reduce the risk of](https://nabtahealth.com/pcos-and-pregnancy/) [miscarriage](https://nabtahealth.com/glossary/miscarriage/) in women with [PCOS](https://nabtahealth.com/glossary/pcos/). * Preliminary work suggesting that preventative treatment with metformin reduces the risk of [](https://nabtahealth.com/gestational-diabetes-8-things-you-should-know/)[gestational diabetes](https://nabtahealth.com/glossary/gestational-diabetes/) has not been replicated in newer studies. The final conclusion reached by the Society was that they would not recommend metformin as the first line treatment approach for [ovulation](https://nabtahealth.com/glossary/ovulation/) induction. Medications such as clomiphene citrate, known to be an [ovulation](https://nabtahealth.com/glossary/ovulation/) inducer, are generally more effective than metformin for women who are experiencing [PCOS](https://nabtahealth.com/glossary/pcos/)\-related fertility issues. In addition to these findings, other studies have found that there is no consistent evidence that metformin improves the signs of [](https://nabtahealth.com/masculine-hormones-in-women/)[hyperandrogenism](https://nabtahealth.com/glossary/hyperandrogenism/). #### **The outlook for metformin as a [PCOS](https://nabtahealth.com/glossary/pcos/) treatment** Metformin should not be completely discounted as an option for the management of [PCOS](https://nabtahealth.com/glossary/pcos/). Whilst less effective than other options, metformin has been shown to restore [ovulation](https://nabtahealth.com/glossary/ovulation/) in some women with [PCOS](https://nabtahealth.com/glossary/pcos/). For women with [PCOS](https://nabtahealth.com/glossary/pcos/) clomiphene citrate is commonly used to induce [ovulation](https://nabtahealth.com/glossary/ovulation/), however, not all women respond to treatment with this drug. For the women that do not respond, it is possible that combination therapy with metformin may be more successful at inducing [ovulation](https://nabtahealth.com/glossary/ovulation/). However, the work on this to date is limited. There is a need for longer term studies on metformin, as most studies have only explored short course treatment approaches. [PCOS](https://nabtahealth.com/glossary/pcos/) varies considerably from woman to woman. The presenting symptoms differ in both type and severity, which is why [diagnosing it can be so challenging](https://nabtahealth.com/problems-with-traditional-diagnosis-of-pcos/). Women with [PCOS](https://nabtahealth.com/glossary/pcos/) are prone to other conditions such as obesity and [insulin resistance](https://nabtahealth.com/glossary/insulin-resistance/); they are also at greater risk of developing T2DM and [endometrial cancer](https://nabtahealth.com/a-guide-to-endometrial-cancer/). Whether metformin can be given prophylactically to reduce these risks remains unclear and once again highlights the need for longer-term studies with extensive follow-up periods. #### Will metformin be prescribed as standard to all women that receive a diagnosis of [PCOS](https://nabtahealth.com/glossary/pcos/)? Unlikely. A more valuable course of action would be for doctors to better understand the various [PCOS](https://nabtahealth.com/glossary/pcos/) phenotypes and thus, take a more individualised approach to treatment, deciding which of their patients could genuinely benefit from treatment with the drug. As a final note, the value of [lifestyle modifications](https://nabtahealth.com/is-it-possible-to-reverse-pcos/) should not be understated. Adopting lifestyle changes and losing weight has proven to be, by far, the best approach for managing the symptoms of [PCOS](https://nabtahealth.com/glossary/pcos/). It is also the most effective way for women with [PCOS](https://nabtahealth.com/glossary/pcos/) to reduce their risk of developing T2DM. Medication should remain a contingency strategy for use in those who do respond adequately to lifestyle alterations. Nabta is reshaping women’s healthcare.

There is no definitive rule with regards to how often you should see a doctor if you have [endometriosis](https://nabtahealth.com/glossary/endometriosis/). The main thing is to find a _sympathetic doctor_ who will take the time to listen to any concerns you might have. [Endometriosis](https://nabtahealth.com/glossary/endometriosis/) can be [difficult to diagnose](https://nabtahealth.com/how-is-endometriosis-diagnosed/) and often the [symptoms](../the-symptoms-of-endometriosis) will closely resemble those of other conditions, such as [irritable bowel syndrome](https://nabtahealth.com/glossary/irritable-bowel-syndrome/) ([IBS](https://www.niddk.nih.gov/health-information/digestive-diseases/irritable-bowel-syndrome)). For this reason you may initially be referred to a [gastroenterologist](https://nabtahealth.com/glossary/gastroenterologist/) rather than a [](https://nabtahealth.com/articles/top-10-gynaecologists/)[gynaecologist](https://nabtahealth.com/glossary/gynaecologist/). In fact, even once diagnosed, the best approach may well be to consult a multidisciplinary team of experts, depending on the specific symptoms you are experiencing. #### Looking after your emotional health It is also important to consider that [endometriosis](https://nabtahealth.com/glossary/endometriosis/) can have a large impact on your emotional wellbeing, and thus you need to manage more than just the physical symptoms of the condition. Chronic pain can be psychologically draining, as can putting on a ‘brave face’ in front of friends and family. It is not unusual for [](https://nabtahealth.com/articles/what-medications-are-recommended-for-endometriosis/)[endometriosis](https://nabtahealth.com/glossary/endometriosis/) patients to report feeling isolated and alone and the condition has a strong association with depression. It is important to consult your doctor before these feelings start to overwhelm you. Your doctor should also be able to put you in contact with local support groups, where you will have the opportunity to talk to other women who are in the same position. #### Personalised treatment approach The wide ranging clinical presentation of [](https://nabtahealth.com/articles/how-is-endometriosis-diagnosed/)[endometriosis](https://nabtahealth.com/glossary/endometriosis/) means that every patient ideally needs to have a [personalised treatment plan](https://nabtahealth.com/), tailored to their own requirements. This can take time to optimise, so in the early days after diagnosis, it might be necessary to see the doctor on a regular basis. As symptoms improve, the frequency of visits should subside.

Medication for [endometriosis](https://nabtahealth.com/glossary/endometriosis/), the most common [symptom](https://nabtahealth.com/the-symptoms-of-endometriosis/) of [endometriosis](https://nabtahealth.com/glossary/endometriosis/) is pain, with up to 80% of patients complaining of period pain and up to 50% experiencing chronic pelvic pain. Aside from the physical discomfort and day-to-day limitations that long-term, chronic pain causes, it can also massively impact a patient’s quality of life, potentially leading to psychological conditions including anxiety and depression. The anxiety can be exacerbated in those patients who experience heavy periods every month, which causes additional discomfort and worry. #### Painkillers The first line approach for managing the symptoms of [endometriosis](https://nabtahealth.com/glossary/endometriosis/) are over-the-counter painkillers. Non-steroidal anti-inflammatories ([NSAIDs](https://my.clevelandclinic.org/health/drugs/11086-non-steroidal-anti-inflammatory-medicines-nsaids)), such as ibuprofen, partly function by inhibiting the production of [prostaglandins](https://nabtahealth.com/glossary/prostaglandins/). [Prostaglandins](https://nabtahealth.com/glossary/prostaglandins/) cause the [uterus](https://nabtahealth.com/glossary/uterus/) to contract during [menstruation](https://nabtahealth.com/articles/menopause-the-symptoms-nobody-talks-about/) and this contributes to the [period pain](https://nabtahealth.com/articles/what-is-period-pain/) experienced by patients with _[endometriosis](https://nabtahealth.com/glossary/endometriosis/)_. Reducing the levels of [prostaglandins](https://nabtahealth.com/glossary/prostaglandins/) will reduce the painful [contractions](https://nabtahealth.com/glossary/contraction/). Codeine-based medications and paracetamol-containing products are other options for pain relief. #### Hormone treatment If painkillers do not provide sufficient relief from the symptoms of [endometriosis](https://nabtahealth.com/glossary/endometriosis/) there is the option of hormonal treatment. This is not a suitable option for those who are seeking help for [infertility](https://nabtahealth.com/glossary/infertility/). The endometrial deposits that develop outside the [uterus](https://nabtahealth.com/glossary/uterus/), and are characteristic of the condition, form in response to the hormone [oestrogen](https://nabtahealth.com/glossary/oestrogen/). Hormonal therapy aims to block or reduce the production of [oestrogen](https://nabtahealth.com/glossary/oestrogen/). Frequently prescribed hormonal therapies include the [combined contraceptive pill](https://nabtahealth.com/the-oral-contraceptive-pill/), [progesterone](https://nabtahealth.com/glossary/progesterone/) pills and gonadotrophin releasing hormone (GnRH) analogues: * The combined pill contains [oestrogen](https://nabtahealth.com/glossary/oestrogen/) and [progesterone](https://nabtahealth.com/glossary/progesterone/); it prevents [](https://nabtahealth.com/articles/is-oligo-ovulation-anovulation-a-symptom-of-pcos/)[ovulation](https://nabtahealth.com/glossary/ovulation/) and makes periods lighter and less painful. * [Progesterone](https://nabtahealth.com/glossary/progesterone/) suppresses the growth of endometrial tissue, reducing [inflammation](https://nabtahealth.com/glossary/inflammation/) and pain. * GnRH analogues block [oestrogen](https://nabtahealth.com/glossary/oestrogen/) production, causing the endometrial tissue to shrink and become inactive. These drugs place the body into a temporary [menopausal](https://nabtahealth.com/i-am-post-menopause/) state, and long term use may require further medication to combat [](https://nabtahealth.com/articles/effects-of-menopause-on-the-body/)[menopause](https://nabtahealth.com/glossary/menopause/)\-associated symptoms, such as [hot flushes](https://nabtahealth.com/glossary/hot-flushes/) and bone density loss. #### Alternative options Medication is just one option for the treatment of [endometriosis](https://nabtahealth.com/glossary/endometriosis/). If symptoms persist, another option to consider is [surgery](https://nabtahealth.com/should-i-have-surgery-for-endometriosis/). A fully personalised treatment approach is recommended for each patient, taking into account their age, symptoms, [fertility](https://nabtahealth.com/product/fertility-selfcare/) status and family situation.
