Common questions
Is Daily Health Cycle medical advice?
No. Our guides are general information to help you understand your body and prepare questions for your own doctor. They are not a diagnosis or a substitute for care from a clinician. See our Medical Disclaimer.
Where does the information come from?
Key claims link to their source, usually a major health organization such as ACOG, the NHS, The Menopause Society, the CDC or the NIH, or a published study. Our Editorial Standards page explains how articles are researched and updated.
Who writes Daily Health Cycle?
Jessica Bordo writes the site. Jessica is not a clinician, and the site does not currently have a medical reviewer, which is why every key claim links to its source.
