Lowest Dose Of Progesterone For Hrt

Understanding Progesterone’s Role

Progesterone is a hormone made by the ovaries. The term progestogen is often used when talking about progesterone. Progestogens (or sometimes the term progestins is used) are versions of progesterone. They are synthetic hormone drugs that mimic the body’s own progesterone.

Progesterone primarily helps in regulating the menstrual cycle. This hormone is also involved in supporting and maintaining a pregnancy, as it prepares the womb to receive and nurture a fertilised egg. In addition to these roles, progesterone is used therapeutically in hormone replacement therapy (HRT), in progesterone only contraception and within combined contraception.

HRT consists of 2 hormones – oestrogen and, if you have a womb, a progestogen. Oestrogen in HRT helps manage symptoms of the menopause but it also acts to thicken the womb lining. A thickened womb lining increases the risk of cancer of the womb lining. The progestogen is needed to balance the effects of oestrogen and help mitigate the risk of developing womb cancer. By counteracting some of the proliferative effects of oestrogen on the lining of the uterus, it reduces the potential for abnormal thickening of the womb lining which, in turn, increases the risk of cancer of the womb lining. Thus, progesterone is indispensable not only for reproductive health but also as a protective agent against significant health risks.

Minimum Effective Doses

It is important that an effective dose of progesterone is given – whether this is for contraceptive effect or for protecting the womb lining in HRT. Some patients tolerate one type of progestogen differently to others. If you experience side effects to progestogens, it may not be possible to safely reduce the dose of progestogen, but it may be possible to change the type.

Risks of Inadequate Dosage

Administering an inadequate dosage of progesterone in hormone replacement therapy (HRT) can increase the risk of unscheduled vaginal bleeding.

Furthermore, there is a heightened risk of developing uterine disorders, notably uterine endometrial hyperplasia. Endometrial hyperplasia involves the thickening of the uterus lining, which can sometimes lead to more severe health issues, including the potential for malignant changes. Proper dosing of progesterone and progestogens can help to mitigate these risks, ensuring that the HRT effectively manages menopausal symptoms while safeguarding against the progression of uterine conditions.

It is essential for healthcare providers to monitor HRT, vaginal bleeding and side effects and adjust dosages and types of hormones accordingly to avoid these risks and achieve optimal outcomes in hormone replacement therapy.
