Thanks for your question on Health Care Magic.
I can understand your concern.
By your history and description, possibility of GERD (
gastroesophageal reflux disease) is more.
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
chest tightness, pressure, burping,
nausea etc.
Along with drugs, you need to follow certain below mentioned lifestyle modifications for better to relief.
1. Avoid stress and tension.
2. Avoid hot and spicy food. Avoid junk food.
3. Avoid large meals, instead take frequent small meals.
4. Go for walk after meals.
5. Keep 2-3 pillows under head in the bed to prevent reflux.
6. Loose weight if you are obese.
7. Quit
smoking and alcohol if you have these habits.
Don't worry, you will be alright with all these lifestyle modifications.
Hope I have solved your query. Wish you good health. Thanks.
