Can you die from belly button discharge? What happens?
It would probably depend on what type of discharge, what is causing the discharge.
Since this is not my area of expertise, I searched Google under the key words "belly button discharge" to get these possible sources:

As indicated in most of these sources, if the discharge continues, see your physician.
I hope this helps. Thanks for asking.
