Hyivy Device as Non-hormonal Therapy in Endometriosis

Endometriosis is a chronic, inflammatory, estrogen-dependent disease characterized by ectopic growth of uterine-like cells outside the uterus. People living with endometriosis typically experience debilitating pelvic pain (dysmenorrhea, dyspareunia, dyschezia, dysuria, non-menstrual pelvic pain), and infertility. Endometriosis also has significant negative impacts on quality of life, physical, mental, and social wellbeing.

There is no diagnostic marker nor cure for this chronic disease. Current treatment options include medical therapies (mainly hormonal treatments aimed at suppressing menstruation or growth of the ectopic cells), surgery (to remove endometriotic lesions/nodules), and complementary or alternative therapies (non-medical or surgical options to manage symptoms; heat, mindfulness, diet, yoga, natural remedies, physical therapies, etc.).

Many people living with endometriosis report having used self-management strategies (complementary and alternative therapies) to manage their symptoms, and research on treatments and alternative therapies are consistently ranked among the top endometriosis research priorities. Alternative therapies have the potential to complement existing medical and surgical therapies, offering additional options to manage symptoms like pain.
