Can endometriosis cause upper abdominal pain after eating?

Yes—endometriosis can be linked to upper abdominal pain in some patients, especially when disease involves the diaphragm or upper abdomen. People may describe right-sided upper abdominal discomfort, chest or shoulder pain, or pain that can feel “higher than the pelvis,” and it may follow a cyclical pattern around the menstrual cycle. That said, meal-related upper abdominal pain isn’t automatically endometriosis, and we take it seriously because several GI and non-GI conditions can mimic or overlap with endo.

In our evaluation process, we zoom in on timing (Does it flare with periods or ovulation? Is it consistently triggered by meals?), the exact location, and any associated symptoms like bloating, reflux, bowel changes, or pain with deep breathing. We may also look for common coexisting drivers—such as gut dysbiosis/SIBO or reflux-type conditions—that can amplify inflammation and pain and make symptoms feel confusingly “mixed.” If your pattern suggests diaphragmatic or more extensive abdominal involvement, we can help determine whether advanced imaging and/or a surgical plan that includes inspection of the diaphragm makes sense.

If you’re dealing with upper abdominal pain after eating and you suspect endometriosis, reach out to schedule a consultation so we can map your symptom pattern and build a targeted diagnostic plan. The goal is to avoid assumptions, identify what’s truly driving the pain, and tailor treatment—whether that ends up being excision surgery, addressing overlapping GI factors, or both.
