[Hormone substitution in menopause].

Postmenopausal estrogen deprivation is a major cause for vasomotor and psychic complaints and for urogenital dysfunction, it is also a risk factor for osteoporosis, hip fracture, cardiovascular disease and possibly dementia. Hormone replacement therapy is highly effective in improving hot flushes, insomnia, depression and genital atrophia, but it prevents bone mineral loss and coronary heart disease as well. The potential risk for thromboembolism remains small and there is no final proof for a significant increase of breast cancer. Hysterectomized women may be treated with unopposed estrogens, otherwise progestogens must be added in a cyclic or continuous manner in order to protect the endometrium. Natural estrogens are to be preferred, they may be administered orally, percutaneously or vaginally. Long acting subcutaneous implants are also gaining interest. Prolonged treatment for many years is essential in order to be preventive. Compliance by motivation and comprehensive care is therefore indispensable.
