I AM 64 FEMALE WITH MANAGED HIGH BLOOD PRESURE, 225 LBS; I TAKE TRULICTY SHOTS ONCE A WEEK TO KEEP A1C AT 6; NASCABAL NASAL B-12 ONCE A WEEK; PRESCRIPTION NEXIUM FOR ACID REFLUX. I HAD GASTRIC BYPASS SURGERY IN 2008 AND WENT FROM 385 TO 225. GOOD HEALTH, NO ILLNESSES. LAST COUPLE OF WEEKS I HAVE BEEN INCREASING TIRED. TODAY I WAS WALKING A SHORT DISTANCE AND HAD SHORTNESS OF BREATH AND MY HEART WAS POUNDING. I HAD COME OUT OF AN AIRCONDITOINED CAR AND WALKED BLOCK TO AIR CONDITIONED BUILDING WHERE SYMTOMS SUBSIDED. 2 HOURS LATER SAME SENARIO AND SAME SHORTNESS OF BREATH AND HEART POUNDING. OK ONCE I SAT DOWN. NO PAIN IN ANYWHERE, NOT DIZZY OR SWEATING.
