Nausea and Vomiting with Adenomyosis or Endometriosis
Adenomyosis and endometriosis can both cause nausea, and sometimes vomiting. It often peaks with period cramps and heavy bleeding, but inflammation, bowel irritation and severe pain can bring it on between periods too.

When it flares
It often builds in the days before your period, peaks in the first day or two of bleeding and can flare around ovulation. Nausea that doesn't follow your cycle still deserves a check.

When to get help
Nausea that comes back with your period is reason enough to see an endometriosis specialist, especially alongside pelvic pain or bowel changes. You don't have to keep managing it on your own.
Keep track
For two or three cycles, note the cycle day, how sick you feel, any vomiting, your bowel habits and your medicines. It's the most useful thing to bring to your first visit.
Speak with Us
Book a visit if it:
- Comes back with your period or ovulation
- Comes with pelvic pain, heavy periods or bowel changes
- Gets in the way of eating, sleep or work
- Keeps you reaching for anti-nausea medicine
- Is getting worse, or spreading beyond your period
Your first visit
We go through your history and your notes, then map out next steps together, whether that's tests, imaging or treatment.

What it feels like
How patients often describe it
- It comes in waves that rise from my stomach.
- I feel queasy most of the day.
- I get sweaty, shaky and lightheaded.
- Smells or brushing my teeth set it off.
It can be a mild, queasy feeling most days or sudden waves with cramps, and vomiting can happen when pain peaks. Some people feel it around ovulation, with bowel movements or with deep pain during sex, and it can happen between periods with pain flares, stress or poor sleep. You may lose your appetite or feel full quickly.
Why it happens
Period cramps and prostaglandins
Around your period, the uterus releases prostaglandins, chemicals that make it contract. They can also upset the gut and affect your whole body, bringing nausea, diarrhea and a flu-like feeling. In adenomyosis, the lining grows into the uterine wall, so contractions can be stronger and more painful, and nausea often peaks on the heaviest, crampiest days. Heavy bleeding can also drain your iron, adding lightheadedness, tiredness and nausea.
Inflammation and the bowel
Endometriosis is inflammatory. Lesions release chemicals that irritate the lining of the belly and nearby organs and can slow the gut. When endometriosis is on or near the bowel, nausea and vomiting can be more common and may worsen with eating, bowel movements or constipation. That's one reason it can happen between periods too.
Pain, nerves and medicines
Severe pain sets off the body's alarm response, which commonly brings nausea, sweating and shakiness. Over time, the nerves and gut can become more sensitive, so nausea can linger when you're not bleeding. Some medicines add to it, such as anti-inflammatories on an empty stomach, opioids and some hormonal treatments.

“Nausea that comes back with your period is a clue, not something to put up with. Tell us when it happens and what comes with it, from heavy cramps to bowel changes, and we'll look for what's driving it.”
Why it's often missed
Nausea is easily put down to a stomach bug, reflux, food intolerance or IBS, and these can also happen alongside endometriosis or adenomyosis. The clue is the pattern: nausea that comes back with your period, or flares with pelvic pain, bloating or bowel changes.
It doesn't match how the disease looks, either. Some people with mild-looking disease have severe nausea, and some with extensive disease have little.
How it's diagnosed
Track two or three cycles
Note the cycle day, nausea, vomiting, bowel habits and medicines. Nausea that lines up with your period is a key clue.
Check for other causes
Medicines, reflux, stomach irritation from anti-inflammatories and other gut conditions can cause or add to nausea. A gastroenterologist may help when gut symptoms persist.
Get expert imaging
An endometriosis-focused ultrasound or MRI can show adenomyosis and deep endometriosis near the bowel. A normal scan doesn't rule it out.
See an endometriosis specialist
A specialist puts your timeline, exam and imaging together, and can confirm and treat endometriosis with laparoscopy. Bring your notes.
Treatment options
Treatment depends on what's driving your nausea, and often combines several approaches.
- Medical
Hormonal therapy
Calms the cycle and can lighten bleeding, which can ease period-linked nausea.
Hormonal Therapy - Medical
Pain management
Controlling pain can calm the pain-nausea cycle. Anti-inflammatories sit better with food.
Pain Management - Medical
Anti-nausea medicine
Prescribed for flares, especially if vomiting makes it hard to stay hydrated.
- Surgical
Excision surgery
Removes endometriosis at the root, which can help nausea driven by inflammation, bowel disease or pain flares. Relief isn't always complete.
Surgery overview - Surgical
Adenomyosis surgery
If medicine isn't enough: uterus-sparing surgery in some cases, or hysterectomy once you're done having children.
Adenomyosis care - Support
Flare self-care
Small sips with electrolytes, small bland meals, gentle heat, and ginger or peppermint if they suit you.

Questions people ask
Can adenomyosis cause nausea?
Yes, adenomyosis can cause nausea, especially during heavy, crampy periods. Intense uterine contractions and higher prostaglandin levels can trigger a queasy feeling, which tends to be most noticeable on the heaviest bleeding days and during peak cramping.
Can endometriosis cause nausea and vomiting?
Yes, endometriosis can cause nausea and, for some patients, vomiting. Inflammation in the abdomen, irritation of pelvic organs (especially the bowel), and the body’s nervous-system response to severe pain can all trigger queasiness.
Why is nausea worse on my period?
Nausea can worsen during your period because rising prostaglandins help the uterus contract and can also irritate the digestive tract. Adenomyosis may make contractions more painful, while endometriosis can amplify pain and unsettled stomach feelings.
Can endometriosis cause nausea even outside your period?
Yes, endometriosis can cause nausea even outside your period. This is commonly driven by inflammation and pain signaling, can fluctuate with activity, pelvic pain flares or hormonal shifts across the cycle, and often comes with bloating or bowel changes.
Will endometriosis excision surgery help nausea?
Excision surgery can help nausea, especially when it is triggered by endometriosis-related inflammation, bowel involvement, or intense pain flares. Relief is not always complete, because other gastrointestinal conditions, reflux, or medication effects may also contribute.
How can I manage nausea flares at home?
Try frequent small sips of fluid during a nausea flare; small, bland portions of food can be easier to tolerate than full meals. If nausea is tied to pelvic cramping, gentle heat and light movement, as tolerated, can sometimes reduce the pain and nausea cycle.
