Hello dear, thanks for your question on HCM.
In my opinion you are having mostly GERD (
gastroesophageal reflux disease ).
But better to rule out cardiac cause first.
So get done ecg.
If ecg is normal then no need to worry.
Since you have
nausea, possibility of GERD is more in your case.
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 like
chest pain and nausea.
So better to follow these steps.
1. Avoid hot and spicy food.
2. Avoid stress and tension.
3. Avoid large meals, instead take frequent small meals.
4. Start
Proton pump inhibitors.
5. Go for walk after meals.
6. Keep 2 - 3 pillows under head in bed to prevent reflux.
Don't worry, you will be alright.
