Endometriosis is a chronic gynecological condition in which tissue similar to the lining of the uterus grows outside the uterus, causing inflammation, pelvic pain, and other reproductive health problems. It is widely recognized as one of the leading causes of infertility, making it difficult for some women to conceive naturally. However, fertility is only one part of the story, as the condition may also influence pregnancy outcomes after conception.
Although many women with endometriosis have healthy pregnancies and deliver healthy babies, studies suggest that the condition may be associated with a higher risk of miscarriage compared to women without it. Researchers believe that chronic inflammation, hormonal imbalances, changes in the uterine lining, and immune system dysfunction may all contribute to this increased risk. The degree of risk can vary depending on the severity of the condition and other individual health factors.
In this article, we will examine whether endometriosis can cause miscarriage, explore available treatment options, and share practical tips for supporting a healthy pregnancy with endometriosis.
What Is Endometriosis?
Endometriosis is a chronic condition in which tissue similar to the endometrium, the lining of the uterus, grows outside the uterus. These growths are commonly found on the ovaries, fallopian tubes, the outer surface of the uterus, and the pelvic lining, although they can also appear in other parts of the body in rare cases. Like the uterine lining, this tissue responds to hormonal changes during the menstrual cycle, but unlike menstrual blood, it has no way to leave the body. This can lead to inflammation, irritation, scar tissue, and adhesions.
The exact cause of endometriosis is still unknown, but several factors are believed to contribute to its development. These include retrograde menstruation, where menstrual blood flows backward into the pelvic cavity, genetic predisposition, immune system dysfunction, and hormonal influences. Women with a close family member who has endometriosis are generally at a higher risk of developing the condition themselves.

Symptoms of endometriosis vary from person to person. The most common signs include severe menstrual cramps, chronic pelvic pain, pain during or after sexual intercourse, painful bowel movements or urination during menstruation, heavy menstrual bleeding, and difficulty becoming pregnant. Some women experience only mild symptoms, while others have no symptoms at all and discover they have the condition only after seeking medical help for infertility or persistent pelvic pain.
Can You Get Pregnant With Endometriosis?
Yes, you can get pregnant with endometriosis. Although the condition can make conception more difficult, it does not mean pregnancy is impossible. Many women with mild or even moderate endometriosis conceive naturally and go on to have healthy pregnancies. The chances of becoming pregnant often depend on factors such as the severity of the condition, age, overall reproductive health, and whether other fertility issues are present.
Endometriosis can affect fertility by causing inflammation, scar tissue, and adhesions that may interfere with the ovaries, fallopian tubes, or the implantation of a fertilized egg. In some cases, it can also reduce egg quality or alter the environment needed for fertilization. However, these effects vary widely, and not every woman with endometriosis will experience infertility.

For women who have difficulty conceiving, several treatment options are available. Depending on the individual’s circumstances, a healthcare provider may recommend medication, surgery to remove endometriosis lesions, or assisted reproductive technologies such as intrauterine insemination (IUI) or in vitro fertilization (IVF). Early diagnosis and appropriate treatment can improve the chances of achieving a successful pregnancy.
Why Can Endometriosis Lead to Miscarriage?
While the exact reason is not fully understood, researchers believe that several biological changes caused by endometriosis may increase the risk of miscarriage in some pregnancies. These changes can affect implantation, early fetal development, and the ability of the uterus to support a growing pregnancy. It is important to note that having endometriosis does not mean a miscarriage will occur, but it may increase the likelihood compared to women without the condition.
1. Chronic Inflammation
Endometriosis triggers ongoing inflammation throughout the pelvic region. This inflammation leads to the release of chemicals called cytokines and prostaglandins, which can interfere with embryo implantation and early pregnancy development. An inflammatory environment may also affect the placenta as it forms, increasing the risk of pregnancy loss.
2. Hormonal Imbalances
Many women with endometriosis experience hormonal changes, particularly progesterone resistance. Progesterone is essential for preparing and maintaining the uterine lining during pregnancy. When the body does not respond properly to this hormone, the endometrium may not provide the stable environment needed for the embryo to continue developing.
3. Changes in the Uterine Lining
Endometriosis can alter the structure and function of the endometrium, making it less receptive to a fertilized egg. Even after successful implantation, these changes may affect how well the pregnancy is supported during the first few weeks, which is when most miscarriages occur.

4. Immune System Dysfunction
The condition is associated with changes in the immune system that may interfere with normal pregnancy. Instead of supporting the developing embryo, certain immune responses may create an environment that makes it more difficult for the pregnancy to progress normally. Researchers continue to study how these immune changes contribute to miscarriage risk.
5. Adenomyosis
Some women with endometriosis also have adenomyosis, a condition in which endometrial-like tissue grows into the muscular wall of the uterus. Adenomyosis has been linked to a higher risk of miscarriage because it can affect the uterus’s ability to support pregnancy. In addition, endometriosis may interfere with normal placental development, reducing the flow of oxygen and nutrients to the growing baby during early pregnancy.

Can Treating Endometriosis Reduce Miscarriage Risk?
Treating endometriosis may help improve the chances of a healthy pregnancy for some women, but it does not guarantee that a miscarriage can be prevented. The impact of treatment depends on factors such as the severity of the condition, the woman’s age, overall reproductive health, and the presence of other medical conditions. Because every case is different, healthcare providers develop treatment plans based on each individual’s needs.
Laparoscopic surgery to remove endometriosis lesions and scar tissue may improve fertility and create a healthier environment for conception, especially in women with moderate to severe disease. Hormonal therapies can also reduce inflammation and control the growth of endometriosis tissue before pregnancy, although these medications are discontinued when trying to conceive. For women who have difficulty becoming pregnant, assisted reproductive technologies such as IVF may increase the chances of conception, but they do not completely eliminate the risk of miscarriage.
In addition to medical treatment, maintaining a healthy lifestyle and receiving early prenatal care are important for supporting a successful pregnancy. Eating a balanced diet, staying physically active, managing stress, avoiding smoking and excessive alcohol, and attending regular prenatal appointments can help promote maternal and fetal health. Women with endometriosis should work closely with their healthcare provider before and throughout pregnancy to receive appropriate care and monitoring.

How to Have a Healthy Pregnancy With Endometriosis
While endometriosis can increase the risk of certain pregnancy complications, many women with the condition have healthy pregnancies and deliver healthy babies. Taking proactive steps before and during pregnancy can help support both maternal and fetal health.
- Seek early prenatal care: Schedule your first prenatal visit as soon as you know you are pregnant. Regular checkups help monitor your baby’s development and detect potential complications early.
- Follow your healthcare provider’s treatment plan: Take prescribed medications and supplements only as directed. Do not stop or start any medication without consulting your doctor.
- Eat a balanced, nutritious diet: Include plenty of fruits, vegetables, whole grains, lean proteins, and healthy fats to support your baby’s growth and reduce inflammation.
- Stay physically active: Engage in pregnancy-safe exercises, such as walking or prenatal yoga, if approved by your healthcare provider. Regular activity can improve circulation, reduce stress, and support overall health.
- Manage stress: Practice relaxation techniques such as deep breathing, meditation, or gentle stretching to help reduce stress, which can benefit both you and your baby.
- Get enough rest: Prioritize quality sleep and take breaks when needed. Adequate rest helps your body adapt to the physical demands of pregnancy.
- Avoid smoking and alcohol: Tobacco, alcohol, and recreational drugs can increase the risk of pregnancy complications and should be avoided throughout pregnancy.
- Know the warning signs: Contact your healthcare provider immediately if you experience heavy bleeding, severe abdominal pain, persistent contractions, fluid leakage, or any other concerning symptoms.
- Attend all prenatal appointments: Keeping every scheduled appointment allows your healthcare provider to monitor your pregnancy closely and address any issues as early as possible.
Conclusion
Endometriosis is best known for its impact on fertility, but research suggests it may also increase the risk of miscarriage in some women. Factors such as chronic inflammation, hormonal imbalances, immune system changes, and alterations in the uterine lining may contribute to this risk. However, having endometriosis does not mean that miscarriage is inevitable, and many women with the condition go on to have healthy pregnancies and healthy babies.
Early diagnosis, appropriate treatment, and consistent prenatal care can help improve pregnancy outcomes. If you have endometriosis and are planning to conceive or are already pregnant, working closely with your healthcare provider is the best way to manage the condition and address any potential complications. With the right care and support, a successful and healthy pregnancy is achievable for many women.
