Hi and welcome to HCM. Thank you for your query.
This symptoms are typically found in
gastritis, GERD and especailly in
hiatus hernia. First you should do gastroscopy to evaluate this. Symptoms that are experienced in such conditions are pain and tightness in upper stomach,
bloating, breathing difficulties,
heartburn, feeling of lump and sore in throat, gurgling sound in throat, fatigue and loss of appetite.
Symptoms are aggravated after meal, long sitting, leaning forward, stress and anxiety. In the beginning this is treated by changing dietary habits.
You should avoid alcohol, coffee, smoking, fats and fast food, carbonated drinks and eat more milk and milk products, fruit and vegetables, boiled food and natural beverages and teas. 1 hour after meal you should not sit or lay. Also lay with elevated upper body. If you are
overweight you should do often exercise.
Hope I have answered your query. WIsh you good health.
