Welcome and thank you for asking on Chat Doctor! I understand your concern, and would explain that your symptoms may be related to a metabolic disorder or a vitamin or electrolytes deficiency based on your medical history for celiac disease. I recommend consulting with your GP for a careful physical examination, a resting ECG, a chest x-ray and some blood lab tests:- complete blood count for chronic anemia- kidney and liver function tests-ferritin and hemosiderine plasma levels-blood electrolytes - vitamin B12 plasma levels-thyroid hormone levels an immunological disorder could lead to thyroid dysfunction and celiac disease as well. A head up tilt test may be needed to exclude a possible orthostatic hypotension. Meanwhile, I would advise you to avoid straining physical activity and take plenty of fluids water, juices, to avoid deny Chat Doctor. Hope to have been of help! Best regards,
