I have been getting dizzy when i eat a meal. but as soon as i stand up and start walking i feel better. i am wondering if this is anxiety or something else ?

Dizziness : You may be experiencing postprandial hypotension.This condition causes people to feel lightheaded or dizzy after eating a meal because their blood pressure drops suddenly. You can find out by checking blood pressure before after a meal . This can happen with no reasons or in diabetes etc Eating less Carbs or small quantity at a time . Of course will need to see a doctor in person for detailed hx
