I'm a bit confused by your post.

You first say that the doctor told you that both discs are touching each other do to loss of fluid and you also state that the disc is herniated.

It sounds more like you have misunderstood what the doctor has said, or rather your friend has misunderstood.

Discs herniate for many reasons, and it may not be from loss of fluid in the disc.

if their is total loss of the disc fluid then it is the vertebrae that is rubbing on each other and not the disc.

If there is too much fluid loss from the disc, then there is really nothing that can be done to hydrate them again, even though there are claims from various devices to try to do so. They are really more of a scam then anything else.

If it is just a disc herniation, then conservative measures may solve the problem for your friend and your friend won't need surgery.

If you can provide the info that is on your friend's MRI report, there may be more information that I and others can provide for you.

What type of surgery did your friend's doctor suggest? Has your friend been evaluated by a spine specialist.
