Acid reflux is a very common condition where stomach acid backs up from the stomach into the esophagus, leading to irritation or burning. Normally lower esophageal sphincter (LES), a muscle ring between the end of the esophagus and the stomach tightens to prevent the movement of stomach contents upward. The LES only opens to allow food movement. However, when the LES weakens or relaxes at the wrong time, fluid from the stomach can escape.
Most commonly, acid reflux manifests as heartburn, a sour taste in the mouth or a hoarse voice. If acid reflux is persistent and interferes with your life you may have GERD or gastroesophageal reflux disease, and may need to be seen by a physician.
Avoiding reflux can be simple with lifestyle modifications and medications. In rare cases, surgery may be required.
If you have GERD, you should be paying attention to the drinks you are consuming, how much you consume, and what you do after consumption.
Avoiding drinks that are triggers and consuming drinks that may be beneficial are ways to beat acid reflux. Reconsider your drinking habits and what you do soon after you have had a drink to minimize the chance of getting heartburn or other uncomfortable symptoms.
