In 2000, the World Health Institute released a study which changed the world of hormone replacement therapy (HRT). Once thought of as a major advancement in medicine, it was relegated to fear and innuendo among doctors and patients alike. The study had some positive impacts on how we treat our patients. Two main concepts came out of this study: 1) We need to use the lowest effective dose of medication for the shortest interval. 2) We need to educate our patients on the risks associated with medications.

One concept often lost in this discussion is quality of life. You have to weigh the risks of breast cancer with the concerns you are having with the hot flashes. Ultimately, this is your decision, but one that needs to be made in consultation with your doctor . If HRT will allow you to have a better quality of life in spite of the true risks, I think this is a very reasonable option for you.

Consequently, eating a diet rich in lysine can help to prevent an unwanted flare-up. Good dietary sources include protein-rich foods like yogurt, milk, cheese, eggs, fish, chicken, beef and beans and most fruits and vegetables. Research studies have suggested taking a minimum of 1250 mg of a lysine supplement daily can be effective in suppressing outbreaks. Always talk to a doctor or qualified health professional before taking any dietary supplement.
