Hello doctors, My father is 55 years old who take bp medications. He walks regularly and have this annual physical check up done in which everything else is alright. He has this problem of gas in which he burps a lot and like a lot of gas is produced which he releases through burps HE COMPLAINED THAT WHILE ON MORNING WALK TODAY HE KIND OF FELT LIKE A BIT DIZZY AND LIKE WEIGHTLESSNESS IN HIS LEGS WHILE WALKING BUT AFTER TAKING 8-10 STEPS, THERE WAS A LOT OF BIG BURPS QND AND GAS WAS RELEASED AND THEN EVERYTHING WAS BACK TO NQORMAL. IT HAS HAPPENED TWICE ONLY AND EVERY TIME IT BACK TO NORMAL AFTER BIG BURPS AND GAS RELEASE. PLEASE SUGGEST WHAT THIS COULD BE
