Postprandial panic occurs in people with coronary heart disease and unstable blood pressure, because after a full meal, the blood in the body is redistributed, and the amount of blood circulating in the digestive system of the gastrointestinal tract increases, while the blood supply to other organs is relatively reduced. If you have suffered from coronary heart disease, there is chronic myocardial ischemia, after the meal myocardial blood supply further reduced, it will reflexively cause an increase in heart rate, and lead to panic, and in serious cases can even induce angina. In addition, hypertensive patients can have elevated or lowered blood pressure after meals, and both of these conditions may cause an increased heart rate. Elevated blood pressure after meals is one of the risk factors for cardiovascular diseases in elderly hypertensive patients. Patients are advised to measure their heart rate and blood pressure when they have a panic attack to help clarify whether there are blood pressure fluctuations and tachycardia. Patients with postprandial panic can eat less and more each time and eat light, easily digestible food to help prevent panic symptoms after a full meal.
