Welcome to HCM
We understand your concerns
After careful reading your problem, I can suggest that you might be suffering from gastric disorder or indigestion
. Fullness of stomach and chest area and stool condition clearly suggest that.
Breathless is not necessarily that. The pressure exerted by gastric derangements on the diaphragm pushes the upper chest area and we feel tightness and feelings of breathlessness. These symptoms are available for last 15 days and then you should have consulted a physician.
I suggest you to go for a physician checkup. Also follow a strict diet for two weeks atleast.
Hope I could answer your query. Feel free to contact me if you need further help.
