Hi!
welcome to HCM!
Heartburn and gas formation are the major symptoms of acidity. Our body produces acid to digest the food we eat. However, problem strikes, when it produces more acid than what is required. It is, then, that the gastric juices move from the stomach, into the lower
esophagus, making it dysfunctional. There are a number of reasons that lead to the formation of acidity LIKE
Excessive
smoking,alcohol,Gastro duodenal (peptic) ulcer,Reflux of
gastric acid
Not having meals on time .Eating fried and spicy food on a regular basis .
Being on an empty stomach for a long time ,Negative emotions or
Weakness of the LES .You have already got examined and nothing was found,so you can take antacids available to relieve the symptoms and try to reduce
stress and avoid spicy and oily food.
hope this helps!
