Symptoms
Can endometriosis cause nausea and vomiting?
The short answer
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.

Many people notice nausea is most intense around their period or during pelvic pain flares, and it may come with other symptoms like cramping, bloating, or bowel changes. If vomiting is frequent or severe, our team will want to evaluate hydration risk and look for other gastrointestinal causes occurring alongside (or instead of) endometriosis so we can address the full picture and help you feel better.

Questions people ask next
All symptoms questionsCan 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.
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.
Are GI symptoms common with endometriosis?
Yes, gastrointestinal (GI) symptoms are very common with endometriosis. Many patients experience bloating, constipation, diarrhea, nausea, or cramping, which can flare around a period or persist throughout the month.
Which endometriosis symptoms mean I should go to the ER?
Go to the ER for sudden severe pelvic or belly pain different from usual, or pain with fainting, fever, repeated vomiting or a rigid/swollen belly. Heavy bleeding soaking pads rapidly, pregnancy concerns with pelvic pain or bleeding, chest pain, shortness of breath or coughing blood also need ER care.
