About Venva

Every health claim traces to a peer-reviewed study or to guidance from a major health body, such as the World Health Organization or national clinical guidelines. Sources are numbered in the text and listed at the end of each page, so you can check them yourself.

We prefer large reviews and official guidelines over single small studies, say plainly when the evidence is weak or mixed, and update pages when the guidance changes.

Venva gives general information, never a diagnosis or treatment plan, and always points you to a doctor when it matters. Every symptom page lists the warning signs that mean you should not wait. Read our Medical Disclaimer for more.

If you spot something wrong, outdated or badly sourced, tell us through the Report an error page or email venva.health@gmail.com. We review every report and correct mistakes promptly.

Venva shows no ads or sponsored content and sells no products, so nothing on the site is written to sell you anything.
