Hello
I appreciate your concern
Looking at your description this could be due to
Acid peptic disease or
acid reflux and Aerophagia
Excessive fatigue can be related to liver disease like hepatitis or fatty liver
Shortness of breath can be caused by Lung or
heart disease or some times acid reflux as well
I would like further information to help you better like
Your age and relevant medical history like diabetes, high BP or other metabolic disease
I would advise to immediately consult your doctor for shortness of breath and you can ask for an EKG to rule.out heart disease first and subsequently all your problems
Please follow these guidelines
Avoid smoking and alcohol consumption
Don't lie down immediately food
Avoid meat, diary products and large fatty fried or junk food
Deep breathing exercises will definitely help you
Glucose water if you are not diabetic
Have
multivitamin supplements and lots of fresh fruits and vegetables
Hope this answers your question
Best wishes
