Eat Small Meals
Large, heavy meals require more energy to get digested. This process can cause your blood pressure to drop sharply. [10] This is because blood flows to your digestive tract when you eat. If you eat large meals, your heart rate is likely to increase to balance blood pressure.
Low blood pressure worsened by consuming large meals is more common in older adults. Stress eaters and people who skip breakfast are more likely to experience this because they tend to enjoy binge eating to cope with stress or compensate for not eating.
You can prevent your blood pressure from dropping when you eat by eating your meals frequently in smaller portions. Your blood pressure is also likely to stay stable if the meals you eat are low in carbs.
