Requesting for release from the project

I discussed with my delivery manager about release, he was ready to release but my project manager is not approving. Is there anyway I can approach to convince my project manager? I have given my health issues as reason for release.

Document your health issues and request in an email to your project manager, delivery manager, and HR. Follow up regularly. Taking medical leaves can also emphasize your situation.
