Hello dear,
The symptoms as mentioned in your can be attributed to Gastrointestinal cause.
However, certain investigations like ECG &
Echocardiography should be done to rule out any cardiac pathology for the symptoms.
Heartburn & reflux of acid from stomach is caused due to relaxation of the sphincter at the lower part of esophagus.
Management consists of:
1. Lifestyle modification- like weight reduction, sleeping on the left side, or with upper body raised.
2. Dietary modification- avoid consuming irritating substances such as acidic & rich foods, caffeine, nicotine, and alcohol.
3. Medical management-
Proton pump inhibitors like
Omeprazole,
Pantoprazole (which prevent acid formation in stomach)+
Domperidone preparations (strengthens the sphincter & prevents reflux)
So, it will be better to consult your treating Doctor/ Gastroenterologist.
Investigation like Upper GI endoscopy will be helpful in clinching the diagnosis.
Wish you a good health.
Take care.
