Summary

This trial will compare blood pressure, pain, and platelet activity in women with and without endometriosis during certain tests. Participants will take aspirin and/or placebo and undergo exercise, cold pressor tests, iontophoresis, and blood draw.

Who is the study for?
This trial is for women aged 18-45, with or without endometriosis. It's not suitable for those who are pregnant, breastfeeding, have a high BMI or certain health conditions like cardiovascular disease, diabetes, severe liver or kidney issues, hypertension/hypotension, Raynaud's syndrome; those on medications affecting blood pressure; smokers; recent hormone therapy users; and individuals with skin allergies.
What is being tested?
The study tests how aspirin affects blood pressure and pain in response to stress in women with endometriosis compared to healthy women. Participants will take aspirin or a placebo and undergo exercises and tests to measure neurovascular regulation differences between the two groups.
What are the potential side effects?
Aspirin may cause side effects such as stomach upset or bleeding risks. The placebo should have no active effects but can sometimes cause reactions due to expectations of treatment.
