As long as necessary. But as short as possible. It also depends upon which hormone you are referring. Type 1 diabetes is associated w/pancreatic failure which means no Insulin is produced. In this case, Insulin replacement is lifelong. Hypothyroidism is inadequate production of levothyroxine, so again, replacement is lifelong. Estrogen is trickier. Current thinking is only if you have symptoms, so for as short as possi.
Herbal suppliments. Supplements that are derived from or made from plant materials may contain plant sterols that can be converted in the body to estrogens. Black cosh is the commonest of these products, and is found in many over the counter products.
Invalid. There is no validity to following blood estrogen levels in order to adjust the dosage of hormone replacement. At age 32, I would not expect that you should need hormone replacement, unless you went through early menopause or had surgical removal of your ovaries. In postmenopausal women the dose is adjusted based on symptoms (hot flashes, sleep issues), not blood levels.
If you rub a hormone replacement of estrogen under your arm pits, can it cause you to start your period?
Bleeding is possible. Assuming one is not menopausal, exposure to estrogen or progestin - from many routes, can initiate a vaginal bleed. Of course there are many variables - point in cycle, how much and how often the medication is taken, etc.
I need to know what is the range for healthy blood level of estrogen when on hormone replacement therapy?
No range. There is no meaningful range to follow blood levels. That's not how its done.
Hormone replacement- is the dose and duration of prometrium (micronized progesterone) used in menopause dependent on the dose of estrogen being used by the patient.?
Not necessarily. If you still have a uterus, then you need a combination of estrogen and progesterone. The Progesterone can by taken continuously or in a cyclic fashion. Remember, you are only using the minimum dose of hormones to treat the symptoms that are bothering you. Discuss these doses with your doctor.
Complex issues. Female hormones increase thromboembolism, deep venous thrombosis--progesteron is blamed, more than estrogen--because at menopause, there is changes in blood coagulation? Increase weight, arteriosclerosis, metabolic syndrome all of this increase risk of cardiovascular disease-- estrogen can be given at low dose for brief periods.
Not good. Based on the randomized controlled trial - women's health initiative - hormone therapy is not protective for cardiovascular disease and my even cause strokes, along with blood clots, etc. Bottom line: not recommended for cardiac prevention. If you are young and early postmenopausal with symptoms and have no cardiac disease, short course (1-2 years) may be ok. Talk to your doctor before starting it.
Start early. From the hers study based on long term study of nurses in the uk, early use of hrt is cardioprotective. If, like the whi study, hrt is started at the average age of 61, there is an increased risk of blood clots, heart attack etc.
Hormone replacement therapy. Estrogen alone increases risk of uterine cancer. Adding progesterone increases risk of breast cancer, but reduces risk of uterine cancer. What's the right balance?
Individual. Yes, estrogen alone does increase the risk of uterine cancer over time. And yes the whi showed that the combination of a certain synthetic estrogen and a certain synthetic progestin increased the risk of breast cancer. But most specialists do not use those older types of synthetic hormones and with newer medications the risks are lower and different. So a balance can be achieved.
