Hello dear, thanks for your question on HCM.
In my opinion you are having mostly GERD (
gastroesophageal reflux disease ).
You are on
chemotherapy and these drugs are known to cause GERD.
Anxiety is the added factor for worsening of GERD. And your symptoms like
chest discomfort, nausea, gaseous feeling etc are suggestive of GERD more.
So better to follow these steps for better symptomatic relief.
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.
