Why do you taste bile when burp?

Burping bile, or acid reflux, occurs when stomach contents flow back into the esophagus. This can cause a bitter or sour taste in the mouth, along with a burning sensation in the throat and chest. Acid reflux can be caused by a number of factors, including:

* Hiatal hernia, a condition in which the stomach protrudes through an opening in the diaphragm

* Weak or damaged esophageal sphincter, a muscle that acts as a valve between the stomach and esophagus

* Increased abdominal pressure, caused by obesity, pregnancy, or certain medical conditions

* Certain foods and beverages, such as fatty or spicy foods, alcohol, and caffeine

Acid reflux can be managed by making lifestyle changes, such as:

* Eating smaller, more frequent meals

* Avoiding foods and beverages that trigger symptoms

* Elevating the head of the bed by 6-8 inches

* Losing weight, if overweight or obese

* Quitting smoking

* Avoiding tight-fitting clothing around the waist

If acid reflux is severe or does not improve with lifestyle changes, medication or surgery may be necessary.
