I've been noticing my heart feels like it's pounding pretty hard, especially after eating. Before meals, my blood pressure seems normal, but once I've had something to eat, it shoots up to around 130. Could this be linked to any vitamin deficiencies I'm not aware of?

The symptoms you are experiencing may be related to a condition called postprandial hypotension, which is a sudden drop in blood pressure after eating. To help manage this, you can try increasing your fluid and salt intake, eating smaller meals more frequently, and avoiding high-carb or high-sugar foods. Additionally, you may benefit from taking medications like Midodrine to help stabilize your blood pressure. However, it is important to consult with your healthcare provider for a proper diagnosis and treatment plan.
