Thank you for asking on Chat Doctor! I understand your concern. Your symptoms seem to be related to low blood pressure or anxiety. A gastrointestinal disorder causing abdominal pain and low blood pressure may be a possible cause too. Have you ever measured your blood pressure during these episodes? I would like to explain that intestinal problems like gastroenteritis, indigestion or irritated bowel syn Chat Doctor. I recommend you to closely monitor your blood pressure and consult with your GP for a careful physical examination. You should also perform some tests like an ECG, routine blood test, kidney and liver function tests and blood electrolytes. A head up tilt test may be helpful to exclude a possible orthostatic hypotension. Hope to have been helpful! Greetings!
