Hello dear,
The symptoms as mentioned in your post can be due to:
1. Gastritis
2. Excessive gas formation in stomach
3. Gastro esophageal reflux
Headache, neck pain &
mood swing can be attributed to the
electrolyte imbalance, secondary to the Gastrointestinal symptoms.
You need to maintain adequate hydration & nutrition status of your body.
Avoid lipid rich diet & gas forming food products like cabbage, etc.
Do regular exercise & avoid stress.
Symptomatic relief can be obtained by intake of antacids like
Omeprazole or
Pantoprazole (to be taken half an hour before meals) in combination with
Domperidone.
If symptoms still persist, an endoscopy can be carried out to detect any pathology in the Gastrointestinal tract.
Wishing you a good health.
