There are so many causes why heartburn happens and you will just know it if you experience the signs.The risk factor of having heartburn is it can develop into esophagitis.
Eating foods with high content of fat and smoking can totally affect the function of your LES, which stands for Lower Esophageal Sphincter. With this, acid reflux will reflux into the esophagus and if LES fails, you will surely feel the heartburn. The usual foods and drinks that you used to eat can also stimulate an increased stomach acid like alcohol, chocolate, acidic foods like oranges, grapes and tomatoes, drinks with caffeine like coffee and tea.
So, if you want to relieve your heartburn, do not eat foods that increase stomach acid. Visit the link below to know how you can cure heartburn: http://tinyurl.com/nrznp7d
