Endometriosis Hormone Replacement Therapy

HRT Use in Endometriosis – Comprehensive Guide

Endometriosis and Menopause

Endometriosis is typically an estrogen-dependent disease active during reproductive age. With menopause, symptoms decrease in most patients, but may not disappear completely.

What is HRT and Why is it Used?

Hormone replacement therapy (HRT) involves replacing the estrogen and progesterone that decrease after menopause. The aim is to reduce hot flashes, bone loss, and symptoms affecting quality of life.

Is HRT Used in Endometriosis?

Yes, it can be used. However, careful patient selection and an appropriate protocol are necessary because estrogen can reactivate endometriosis foci.

Is Estrogen Used Alone?

Estrogen therapy alone is generally not recommended in patients with a history of endometriosis. This is because it can increase the risk of disease recurrence.

Combined HRT (Estrogen + Progesterone)

This is the most preferred approach. The addition of progesterone can reduce the stimulation of endometriosis foci.

Continuous Combined Regimen

Continuous use of estrogen + progesterone is considered safer than cyclic regimens because hormone fluctuations are less.

Preference for Transdermal HRT

Transdermal HRT (patch/gel) is often preferred because it provides more stable hormone levels and may reduce the risk of thrombosis.

Use of Tibolone

Tibolone can be an alternative in some patients because it exhibits both estrogenic and progestogenic effects and may be associated with a lower risk of recurrence.

Risk of Recurrence

While the risk of recurrence of endometriosis symptoms or lesions with HRT use is low, it is not entirely zero.

Which Patients Require More Caution?

More caution should be exercised in patients with deep infiltrative endometriosis, residual disease after surgery, or a history of endometrioma.

How Should Follow-up Be?

Patients initiated on HRT should be regularly followed up, and evaluated if pain or new symptoms develop.

Conclusion

HRT is not absolutely contraindicated in patients with a history of endometriosis. However, it should be administered safely with a combined, low-dose, and individualized treatment approach.
