<s>[INST] For several days, I have been having like heart 'catches' or flutters , I feel it in my throat or little below my throat in center of my chest and it makes me cough...then I feel extremely tired. Also, I've had an upset stomach and unable to eat much, because I feel full, but when I eat anything, sometimes I kind of burp it up .... I have had stomach pain several times over the last five days as well. What is this? [/INST] Hi,Welcome to HCM.You are suffering from GERD - gastro esophageal reflux disease.It occurs due to an incompetent lower esophageal sphincter.You need to take a ppi tablet in combination with a prokinetic drug like pantaprazole-levosulpride combination.Also dont eat full stomach, keep it a little empty, and don't lie down for an hour or two after a meal.And no tea, coffee, soda drinks, spicy and fatty foods and chocolates. Keep two pillows under your head while sleeping.RegardsDr. Ashish Verma </s>
