MHT

Meaning

Menopausal Hormone Therapy, MHT, administers exogenous hormones, primarily estrogens, with or without progestogens, to manage symptoms of menopausal transition and postmenopause. This therapeutic approach replaces naturally declining ovarian hormones, directly addressing specific physiological changes. It offers a targeted intervention for hormonal shifts.

Context

MHT addresses the hypoestrogenic state of menopause within the endocrine system, resulting from declining ovarian follicular activity. Reduced ovarian estrogen and progesterone production impacts neurological, cardiovascular, and skeletal health. MHT introduces hormones interacting with specific receptors, alleviating effects of this natural hormonal change.

Significance

MHT holds clinical importance for individuals experiencing bothersome menopausal symptoms, such as hot flashes and genitourinary changes. It also aids in preventing bone mineral density loss, reducing osteoporosis and fracture risk. Careful assessment allows clinicians to weigh benefits against associated risks, supporting improved well-being.

Mechanism

MHT’s biological process involves administered estrogens binding to estrogen receptors (ERα and ERβ) in target cells, initiating signaling that modulates gene expression. This restores estrogenic effects. When progestogens are included, their action counteracts estrogen’s proliferative effect on the endometrium, preventing endometrial hyperplasia and reducing endometrial cancer risk.

Application

MHT is applied via various formulations and routes, including oral, transdermal patches, gels, and vaginal preparations. Protocols are individualized based on symptom severity, history, and patient preference. Estrogen-only therapy is for hysterectomized women; combined estrogen-progestogen therapy protects the uterine lining. The objective is the lowest effective dose for the shortest duration.

Metric

MHT effectiveness is monitored through clinical assessment of symptom resolution and patient well-being. Providers evaluate symptom scores, assess overall quality of life, and conduct routine physical examinations. Bone mineral density may be assessed periodically via DXA scans when osteoporosis prevention is a key objective. Lipid profiles and blood pressure are also routinely checked.

Risk

Potential clinical risks with MHT require careful evaluation. Combined estrogen-progestogen therapy carries a small increased breast cancer risk with prolonged use. Both estrogen-only and combined MHT involve risk of venous thromboembolism and stroke, varying by administration route and individual factors. Unopposed estrogen therapy in women with an intact uterus increases endometrial hyperplasia and cancer risk. Informed discussion is essential.
