Endometriosis is a painful condition that affects millions of people around the world. It occurs when tissue similar to the lining of the uterus grows in places outside the uterus. These growths can appear on the ovaries, fallopian tubes, bladder, bowel, and other areas in the pelvis.
Even though the tissue is outside the uterus, it still behaves like normal uterine tissue during the menstrual cycle. It can swell, break down, and bleed, which causes irritation and inflammation. Over time, this process can lead to severe pelvic pain, fatigue, heavy periods, and sometimes fertility problems.
For many people living with endometriosis, daily life can become extremely difficult. The pain can be so severe that it interferes with work, study, relationships, and normal activities.
Doctors estimate that about one in nine people assigned female at birth may develop endometriosis at some point in their lives. Despite how common the condition is, effective treatments are still limited, and many patients struggle to find relief.
Current treatments usually focus on managing symptoms rather than curing the disease. Doctors often prescribe pain medications, hormonal treatments that suppress the menstrual cycle, or surgery to remove the abnormal tissue.
However, these options do not work for everyone. Hormonal treatments can cause unwanted side effects, and surgery does not always prevent the condition from returning. Because of these challenges, researchers are searching for new ways to help people manage their pain and improve their quality of life.
A new study led by researchers at the University of Otago in Wellington, New Zealand, suggests that medicinal cannabis could offer another possible option for treating endometriosis-related pain.
The research was led by Dr. Claire Henry from the Department of Surgery and Critical Care. The findings were published in the scientific journal BMC Complementary Medicine and Therapies.
The study followed 28 participants who were diagnosed with endometriosis or chronic pelvic pain related to the condition. Each participant was prescribed cannabidiol, commonly known as CBD, which is a compound found in cannabis plants.
CBD does not produce the “high” that is associated with another cannabis compound called THC. Some participants in the study used CBD oil alone, while others used CBD oil together with small amounts of dried cannabis flower. The treatment period lasted for three months.
During the study, participants carefully recorded their pain levels every week. They used a simple numerical scale where zero meant no pain and ten represented the worst pain imaginable. This allowed the researchers to track how their pain changed over time.
Participants also completed a detailed questionnaire about their health and daily life before the study began and again after twelve weeks. At the end of the study, seventeen participants also took part in interviews where they described their experiences using medicinal cannabis.
The results showed encouraging improvements. On average, overall pelvic pain among the participants decreased from 5.4 to 3.7 on the pain scale. The most severe pain they experienced dropped from an average score of 7.6 to 5.3. These changes may appear small, but for people living with chronic pain, even moderate improvements can have a large impact on daily life.
Participants also reported improvements in sleep and anxiety. Many people with endometriosis struggle with poor sleep because of constant pain. Anxiety can also increase when people worry about unpredictable pain episodes.
The researchers found that the improvements in sleep and anxiety were almost as important to participants as the reduction in pain itself. Together, these changes contributed to noticeable improvements in overall quality of life.
Some participants described the effects as very meaningful. One person explained that the treatment helped them feel well enough to consider returning to work after being unable to work for three years because of their condition. Another participant said their health had improved so much that they were beginning to try for a baby.
Many people in the study had previously tried strong pain medications, including opioid-based drugs such as tramadol. While these medications sometimes helped reduce pain, participants reported that the relief was often inconsistent.
In addition, opioids can cause unpleasant side effects such as nausea, dizziness, and extreme tiredness. Some patients also worry about long-term dependence on these medications.
In comparison, participants reported very few side effects from CBD. Many described it as a gentler treatment that still helped manage their symptoms. While CBD did not work for every participant, several people felt that it provided meaningful relief without the heavy side effects associated with other pain medications.
Dr. Henry emphasized that these results are only an early step in understanding how medicinal cannabis might help people with endometriosis.
Because the study involved a relatively small number of participants, larger clinical trials are needed to confirm the findings. Future research will also need to explore how CBD works in the body to reduce pain and which patients are most likely to benefit.
The researchers also want to study the long-term safety of medicinal cannabis for people with endometriosis. Pain management for this condition is often complex and personalized. Different people respond differently to treatments, so doctors must carefully consider individual needs when developing treatment plans.
Overall, the study provides promising early evidence that medicinal cannabis could become another tool for managing endometriosis symptoms.
While it is not a cure, it may help reduce pain, improve sleep, and ease anxiety for some patients. These improvements can make a significant difference in quality of life for people living with a chronic and often debilitating condition.
