<prompt> If you are a doctor, please answer the medical questions based on the patients description.Recently on 2 different days; while out walking at a brisk pace, I had a strong flutter in my chest that only lasted a second or two. I have hypothyroidism and in the past have had this sensation, but it was not really in the center of my chest. I have noticed also that my acid reflux has been more annoying. Should I be more concerned this thime?  <response>: Respected user, HiT hanks for using Healthcaemagic.come have evaluated your query thoroughly. Chest flutter is in relation with irritation of underlying esophageal mucosa from the acid reflux only. Once thyroid hormone levels should also be evaluated to check for any alterations. Suggestions for better recovery - Chat Doctor. - Consume more of soft, light diet .- Avoid oily, spicy, non veg, hot beverages, chilly, excess ghee, dairy fat, junk food.- Regular intake of proton pump inhibitor as omeprazole or pantoprazole till full recovery from acid reflux is better.- Avoid smoking, alcohol.- Avoid stress, anxiety.- Have regular sound sleep of 8 hrs.- Regular walking with deep breathing exercises, YOGA support great. Hope this clears your query. Welcome for any further assistance. Regards dear.
