Immediate Therapy

• If you are lying down, sit upright, then stand up straight. This posture will help ward off the acid and keep it down. Slowly drink a full glass of cool water. If you are not carrying a baby or don't have hypertension, drink another half a glass of water mixed with 1 tbsp. of baking soda.
  
  

What to Eat

• Eat foods that can act like antacids and help soothe the burning feeling of heartburn. Include a banana in your daily diet plan. If you are prone to frequent heartburn and indigestion complaints or are already in the middle of an attack, have fruits such as pineapples and papayas or their respective juices. These can help ease your stomach naturally. Even 1 tsp. of of mustard works instantly to reduce the effects of heartburn. Because heartburn might be caused by a lack of acid, taking a gulp of vinegar might give the precise dosage of extra acid the stomach requires for proper digestion of food. You could also try chamomile tea made with licorice or a mixture of clove oil and water, dried powdered ginger root, or turmeric capsules.
  
  

What to Avoid

• Though drinking milk might give you a good sensation and soothe your throat and stomach, the proteins and fats in it will actually induce extra acid production, worsening the heartburn effect. While mints give you a temporary cooling effect, they actually loosen the tiny valve located between the stomach and esophagus, allowing acid to travel upward and heighten heartburn unease. Heartburn and indigestion at night are generally caused by particular substances such as caffeine-enriched drinks such as tea and coffee, carbonated beverages and soda, alcoholic products, chocolate, excessive garlic, tomatoes and tomato-based products, and juicy citrus fruits. Because of their acidic contents, stay away from these items.
  
  

Medication

• You also have the option of trying any of the numerous antacids sold over the counter at the pharmacy.
  
  

General Measures

• Eat a couple of hours before bedtime. Try to sleep on your left side or at an angle of sorts to prevent the stomach acid from traveling upward. Always eat slowly so digestion can start with your mouth enzymes. Also, if you are suffering from heartburn and indigestion, apply a hot water bottle on you liver area or upper abdomen to the right. This will aid your gallbladder and liver in their digestive activities. Losing weight also helps in the long run.
