Hello Nasywa, thank you for the question

Your symptoms lead to orthostatic hypotension. Orthostatic hypotension is a decrease in systolic pressure by 20 mmHg or diastolic by 10 mmHg when standing for a period of 3 minutes or more compared to blood pressure in a sitting or lying position. This occurs due to the inadequate response of the body's autonomic nervous system to changes in blood pressure that are significant due to changes in position. Complaints can be in the form of syncope, tightness, blurred vision, dizziness, lightheadedness, weakness, nausea, or palpitations.

The body's response due to changes in position is regulated by the heart and blood vessels and the autonomic nervous system. Standing position causes a lot of blood to gather in the lower limbs as much as 500-1000 ml. This will increase the response of sympathetic nerves in the body in the form of increased blood vessel resistance, backflow to the heart, to an increase in cardiac output to prevent excessive blood pressure drop. To compensate for these conditions the body will reduce systolic and diastolic blood pressure and increase the frequency of the heart rate. Because the work of the heart increases that's what causes the symptoms of palpitations.

To prevent this, you should avoid foods that are high in carbohydrates before doing long standing activities, avoid alcohol consumption, and make sure you consume adequate fluids. Add salt consumption in the food that is as much as 1-2 grams 3 times per day. Also do sports like squatting. Can also maneuver other movements that many involve the lower extremities, arms, and abdominal muscles when changing positions or standing for long periods.

So, hopefully this information can be useful
