How does this condition affect my body?

There's less fluid to surround, support and cushion your brain when you have a CSF leak. If the leak is small, it might not cause noticeable effects, or you might notice symptoms and mistake them for something else.

If the leak is large enough to cause intracranial hypotension, your brain will sink downward in your skull, putting too much pressure on its lower sections. That can disrupt how those parts of your brain work, causing symptoms ranging from minor and barely noticeable to severe and unbearable.
