Hello! Thank your for asking on Chat Doctor! Regarding your concern, your symptoms may be related to anxiety or low blood pressure. Have you measured your blood pressure during these episodes? It is important to closely monitor your blood pressure in sitting and standing up position. A decrease in your systolic blood pressure, more than 20\u00a0mm Hg when standing up may be indicative of orthostatic hypotension. I recommend consulting with the GP for a careful physical examination, a resting ECG and some lab tests (a complete blood count for anemia, thyroid hormone levels, kidney and liver function tests, blood electrolytes) to find out the possible cause. A head up tilt test is necessary to rule in/out orthostatic hypotension. Hope to have been of help! Best wishes,
