There is no single best treatment for endometriosis. The most effective approach depends on your symptoms, whether you want to become pregnant, how deeply the tissue has grown, and how much the condition affects your daily life. Current guidelines from ACOG emphasize shared decision-making: some people do best with medication alone, others need surgery, and many benefit from a combination. What matters is matching the treatment to your specific goals.
Starting With Hormonal Medication
For most people with endometriosis pain, hormonal therapy is the first step. The goal is to lower estrogen levels or suppress your menstrual cycle, since estrogen fuels the growth of endometrial-like tissue outside the uterus. Combined oral contraceptive pills are the most commonly prescribed option and can be started based on symptoms alone, without surgery to confirm the diagnosis. In clinical trials, women taking the pill reported meaningfully lower menstrual pain scores compared to placebo, though the overall quality of that evidence is considered low.
Progestin-only options, including hormonal IUDs, pills, and injections, work by thinning the uterine lining and often stopping periods altogether. These tend to be effective for pain and are sometimes better tolerated than combination pills. Your doctor may recommend trying one or two hormonal options before considering anything more aggressive.
Newer Oral Medications That Target Estrogen
A newer class of drugs, oral GnRH antagonists, has changed the treatment landscape in the last several years. These pills work by blocking hormone signals in the brain that trigger estrogen production. Unlike older injectable versions, they don’t cause an initial surge of symptoms (called a “flare effect”) and can be taken by mouth. They also suppress estrogen in a dose-dependent way, meaning doctors can dial the effect up or down.
The trade-off is that lowering estrogen brings menopause-like side effects. Hot flashes are the most common complaint across all drugs in this class. Headaches, sweating, and bone density loss also occur, with higher doses carrying greater risk. One drug in this class showed average bone density loss below 1% at the lower dose but 2.6% at the higher dose. To offset this, these medications are often paired with a small amount of hormonal “add-back therapy,” which protects bones and reduces hot flashes while still keeping endometriosis in check.
When Surgery Makes Sense
Surgery becomes an option when medication doesn’t control your pain, when imaging shows deep or extensive disease, or when you want a definitive diagnosis. Laparoscopic surgery (performed through small incisions with a camera) is the standard approach. Surgeons can either excise (cut out) or ablate (burn away) endometriosis lesions, and the difference matters.
A meta-analysis comparing the two techniques found that excision produced significantly greater improvement in period pain, pain with bowel movements, and chronic pelvic pain at 12 months after surgery. The reduction in chronic pelvic pain was especially notable, with excision patients scoring substantially better on standardized pain questionnaires. Pain during sex also trended in favor of excision, though the difference didn’t quite reach statistical significance. If you’re pursuing surgery, excision by an experienced surgeon is generally considered the more thorough option.
For deep infiltrating endometriosis that involves the bowel, bladder, or ureters, surgery is more complex and carries higher complication risks, including the possibility of needing bowel resection or developing postoperative fistulas. These cases are best handled at specialized centers with multidisciplinary surgical teams.
Fertility and Endometriosis
If you’re trying to conceive, the treatment calculus shifts considerably. Most hormonal therapies suppress ovulation, so they’re off the table while you’re actively trying to get pregnant. For mild to moderate disease (stage I or II), laparoscopic surgery to remove visible endometriosis can improve the rate of ongoing pregnancy.
For more advanced disease, IVF is often the most direct path. One study comparing IVF outcomes in 78 women with surgically confirmed endometriosis to 157 women with tubal infertility found no significant differences in implantation rates, clinical pregnancy rates, or live birth rates between the two groups. This is reassuring: endometriosis doesn’t necessarily mean worse IVF results, particularly when lesions have been surgically treated beforehand. Many fertility specialists recommend a course of hormone-suppressing medication after surgery and before starting IVF to create the best possible conditions.
Managing Pain Without Hormones
Not everyone can or wants to use hormonal treatment. NSAIDs like ibuprofen remain a mainstay for period pain, though they address symptoms rather than the underlying disease. For chronic pelvic pain that has developed a nerve-related component, gabapentin (a medication originally designed for nerve pain) has shown benefit. A meta-analysis of four trials found that gabapentin significantly lowered pain scores at three months compared to placebo, and the improvement on one pain scale persisted at six months. Dizziness is the most common side effect, with drowsiness and visual disturbances reported in some trials.
Pelvic floor physical therapy is another non-hormonal option that helps many people. Endometriosis pain often causes the pelvic floor muscles to tighten chronically, creating a secondary source of pain that persists even after the endometriosis itself is treated. Working with a specialized physical therapist can break this cycle.
Diet and Lifestyle Factors
Dietary changes won’t replace medical treatment, but growing evidence suggests they can meaningfully support it. The Mediterranean diet, rich in fruits, vegetables, whole grains, fish, and olive oil, has shown promise in reducing the production of inflammatory compounds that worsen endometriosis symptoms. Several studies have found that vitamin D supplementation can reduce pelvic pain and improve inflammatory markers. Combined supplementation with vitamins C and E has also been linked to lower pain and reduced oxidative stress.
On the flip side, diets high in red meat, processed foods, and animal fats appear to worsen symptoms. While no single food will cure endometriosis, shifting toward an anti-inflammatory eating pattern is one of the few things you can control directly, and the evidence is tilting in favor of its benefits.
Putting It All Together
The current approach to endometriosis treatment is individualized and stepwise. Most people start with hormonal medication, and many find adequate relief there. If first-line options don’t work, newer GnRH antagonists offer a more targeted approach with manageable side effects. Surgery is reserved for cases where medication fails, deep disease is present, or a definitive diagnosis is needed, with excision preferred over ablation when possible. Fertility goals may accelerate the timeline toward surgery or IVF. And throughout all of this, non-hormonal pain management, pelvic floor therapy, and dietary adjustments can fill in the gaps that any single treatment leaves behind.
The most important factor in outcomes isn’t which treatment you choose first. It’s whether your care team listens to your priorities and adjusts the plan as your needs change over time.
