This topic is about someone who has been experiencing persistent dizziness after undergoing a jejunostomy following a stroke. Despite thorough medical evaluations, the cause of the dizziness remains unidentified, and various treatments have not provided relief. The person is looking for advice or further steps to take. Here are some suggestions and insights that might help:

1. When getting up from sitting or lying down, do so slowly to avoid sudden drops in blood pressure that can make dizziness worse.

2. While dizziness related to anesthesia is possible, it usually goes away quickly. If symptoms persist, further investigation is needed.

3. The dizziness might be due to residual effects of the stroke or general weakness after illness. Try balance-training exercises while holding onto something stable, and keep your eyes open, focusing straight ahead.

4. Consider seeing an ENT specialist to check for vestibular dysfunction. Formal vestibular testing can help identify inner-ear causes of vertigo.

5. Look for a physical or occupational therapist who specializes in vertigo, sometimes found in a "dizzy clinic." They can provide targeted maneuvers and exercises that often resolve dizziness after surgery.

6. Ensure you are well-hydrated, as dehydration can worsen balance issues.

7. Follow up with your stroke or neurology team to rule out the possibility of recurrent or multiple strokes. Persistent vertigo along with swallowing difficulties might indicate brainstem involvement.

8. Discuss with your doctor the possibility of underlying clotting or vascular disorders that could increase stroke risk:
- Antiphospholipid syndrome (APS): Testing for specific antibodies can help, and long-term anticoagulation may be necessary if positive.
- Patent foramen ovale (PFO): A heart defect that might allow clots to reach the brain.
- Giant cell arteritis (GCA) or other conditions that inflame and block cerebral arteries.

9. Managing complex stroke-related vertigo is best done at a major university or tertiary care stroke center, where a team of specialists in neurology, cardiology, rheumatology, and rehabilitation can provide comprehensive care.
