What Causes Excessive Nasal Discharge After Eating?

Question: Continuously from last 3 nights, I am having clear liquid following from my nose. Previously it used to happen when I had heavy dinner. But in last 3 cases, my dinner was very normal. Is this because of heavy snoring or else ?
Brief Answer:
Possible Spontaneous CSF rhinorrhea?Need confirmation
Detailed Answer:
Hello, Sir.
I can understand your concerns.
This clear liquid should be evaluated further to rule out CSF rhinorrhea.
This is a condition where cerebrospinal fluid from the brain leaks through the nose.
This can spontaneous in few individuals without any antecedent cause like trauma to the nose.
This leakage is not related to heavy snoring and heavy dinner.
For confirmation, I advise you to get a Beta2 transferrin test.This is currently single best laboratory test for identifying the presence of CSF in the sinonasal fluid.Once positive, further investigations may be carried out.
Post your further queries if any.
Thank you

Made sure that from last 2 days, I ate as minimal dinner as possible and there has been no further liquid flow during sleep. Let me add more clarity. It happens in between deep sleep and feels like something coming out of the food pipe and entering wind pipe because of the snoring. In one of cases I can feel the after taste of last eaten food.
Since You have mentioned CSF, without the Fluid is their any other method of confirming the CSF ?
Could this be some sort of Acid reflux ?

Brief Answer:
Acid reflux needs to be ruled out
Detailed Answer:
Hello, Sir.
I can understand your concern.
Without the fluid, you can go for a CT scan to assess for any skull base defects. This test is relatively very specific.
The possibility of Acid reflux with coexistent hiatal hernia is also high.
For this an upper GI endoscopy can clear all doubts.
