When the contents of the stomach flux into the esophagus, you will experience acid reflux.
The contents consist of acid and pepsin that are released by the stomach.
Both of them aid the digestion of food.
All the symptoms are caused by the spill over of stomach acid into esophagus, lungs and throat.
The most common symptom of acid reflux is heartburn.
You will feel the burning sensation from the stomach to the throat especially when you lie down on your back, bend forward and finish eating a heavy meal.
Other common symptoms include

• acid regurgitation
• bad breath
• chest pain
• husky voice
• interrupted sleep
• tightness in the throat
• coughing
• wheezing

Acid reflux disease is not a health issue that you can ignore.
It may look like a just ordinary health condition but failure to recognize the symptoms can lead more serious consequences.
The stomach acid causes damages to your body.
Here are 4 consequences that you need to pay attention if you fail to notice the symptoms.

   With this condition, solid and liquid foods may not flow into your stomach easily.
   You feel that the food is trapped in the esophagus.
   
2. Damage on the lining of the esophagus due to stomach acid can lead to Barrett's Esophagus.
   About ten percent of this condition can progress into esophagus cancer.
   
3. Acid reflux can result in apnea.
   This is a fatal condition when you stop breathing while you are asleep.
   
4. The symptoms of heartburn resemble the symptoms of a heart attack.
