Thanks for your question on HCM.
In my opinion you are having reflux disease associated problems. It is known as GERD (
Gastro Esophageal Reflux Disease ).
It is due to laxity of gastroesophageal sphincter.
Because of this the acid of the stomach tends to come up in the
esophagus and cause the symptoms.
You are also having
hiatus hernia. This along with GERD can cause symptoms like you are having.
So try to follow these steps for better symptomatic relief.
1. Avoid hot and spicy food.
2. Avoid large meals, instead take frequent small meals.
3. Avoid stress and
anxiety.
4. Start
proton pump inhibitor.
5. Go for walk after meals.
6. Keep 2 - 3 pillows under head in the bed.
7. Avoid smoking and alcohol if you have this habit.
8. Loose weight if you are obese.
If not improve with these than you may need surgical correction of hiatus hernia.
