Why do I sweat during an endometriosis flare?

Sweating during an endometriosis flare is often your body’s stress-response to pain and inflammation. When pain ramps up, the nervous system can shift into a “fight-or-flight” state, which releases stress hormones and can trigger sweating, chills, shakiness, and a feeling of being overheated. Inflammation itself can also contribute to temperature dysregulation and that "flu-like" flare sensation many patients describe.

It can also be a clue that more than one mechanism is active at once—such as cramping plus pelvic floor muscle guarding, bowel or bladder irritation, or nervous system sensitization after months or years of repeated pain. Some patients notice sweating more around hormone shifts (like right before bleeding) or when certain symptoms spike (GI upset, nausea, diarrhea), which can amplify the autonomic “sweat” response.

Because sweating isn’t specific to endometriosis, we look at the full pattern—timing in your cycle, associated symptoms, medications/hormonal suppression, and whether you’re having red-flag symptoms like fainting, chest pain, or true fever. If this is happening to you, our team can help you sort out whether it fits a typical flare physiology or whether another condition may be overlapping, and build a plan that addresses both symptom control and the underlying disease.
