How can I help my gf through perimenopause?

Suggest hormones. There is still very good evidence that all women barring the few with absolute contraindications to hormone replacement therapy, will benefit significantly from hrt. Too numerous to mention here are the benefits of hrt. Minimal risks in most patients. The biggest negative for the patient would be the cosmetic changes. Ten years of skin wrinkling, acne and hair loss in the first 1-2 years.
