Brief Answer:
Vagal nerve injury related to migraines?

Detailed Answer:
Thank you for your question. If your migraine headaches are of recent origin then, it is highly unlikely that any denervation of the vagus nerves is responsible. Far too much time would've elapsed from the time of your surgery to make any connection possible.

If your headaches began immediately or shortly following your bariatric procedure then, still it is not an automatic connection simply because we do not have any universally accepted theories that there are any direct links between vagal nerve damage whether it be incidental to other surgical procedures or planned as in a vagotomy. Migraine headaches are believed to be initiated and promulgated by the Trigeminal neurovascular complex and this is not under any direct control by the vagus nerve.

There are some studies and cohorts of patients who have demonstrated improvements to their migraine headaches (diagnosed as primary headaches) using methods of VAGAL NERVE STIMULATION using devices and such, however, this does not imply that any LACK of vagal nerve function in the body would automatically trigger the onset or development of migraine headaches.

If your situation of bodyweight or other functions of the GI tract, etc. have not appreciably changed since developing your headaches then, I would suggest a review of your situation by a headache specialist locally who may ask you to start documenting specific parameters of your headaches in what we refer to as a headache log. The log or diary will help the neurologist determine whether or not you are suffering from PRIMARY vs. SECONDARY headaches. If your headaches are determined to be as a result of your surgery in some way then, they would be classified as SECONDARY HEADACHES and their treatment would depend upon the exact cause. If on the other hand, they are PRIMARY in nature such as would be the case with migraines, tension type, clusters, or trigeminal autonomic cephalgias then, treatment could be offered using standard approaches of both medication and other forms of intervention not necessarily related to pharmacological means.

If you've not been seen in a while for your PSEUDOTUMOR CEREBRI (now referred to as IDIOPATHIC INTRACRANIAL HYPERTENSION- IIH) then, it may serve to be seen by a neurologist to make sure that entity either hasn't returned or isn't in some beginning stage of re-occurring.
