Procedures & Tests A–Z — What to Expect, Explained

Plain-language pages for 254 common procedures and tests: what each one is, why it is done, how to prepare, what happens during it, what recovery or aftercare usually involves, and the risks your team will discuss with you. Many pages also link to real procedure videos from the MedicalVideos.com library so you can see what the test or operation involves.

Preparation is specific to each procedure and to you — fasting, pausing blood thinners, arranging an escort after sedation, and pre-procedure tests are common themes, and each page in this guide covers them. Always follow the instructions sent by your own hospital or clinic: they override any general guide, including this one.

Most tests in this guide are painless or use local anaesthetic, sedation or general anaesthetic as appropriate, and each page describes honestly what people usually feel — for example pressure rather than pain during a caesarean under spinal anaesthetic, or brief stinging with injections. If you are anxious, tell your team beforehand: there is almost always something that can be adjusted.

Yes — where a page shows videos, they are matched from the MedicalVideos.com library by the procedure name, so they show the actual procedure or its direct examination. Some clinical and surgical footage is graphic; that is the nature of a medical video library created for students, clinicians and informed patients. Pages without a confident match show no video rather than an unrelated one.

No. These pages explain procedures once a clinician has recommended them; they cannot weigh your symptoms, examination and test results. If you are deciding about a procedure, use the page to prepare your questions, then decide together with your clinical team.
