What's the matter with headache and brain swelling after eating

After a meal, headache and brain swelling are more common in three situations. The first is that after a meal, due to the peristaltic movement of the gastrointestinal tract, the blood pressure is increased, and the patient shows hypertensive headache and head swelling symptoms. The second is that after a meal, the blood in the gastrointestinal tract increases, and the blood supply to the limbs and brain decreases, showing the phenomenon of insufficient blood supply to the brain, while showing dizziness and brain swelling. Third, if the elderly showed headache and brain swelling after eating, consider whether there is a rare postprandial hypotension in neurology. It is recommended that the patient measure blood pressure before and after meals, and compare blood pressure. If postprandial hypotension is shown, active treatment should be given, because it will not only cause headache and brain swelling, but also syncope in severe cases.
