Does anybody know about GERD?? If no, let me tell you. I also did not know about this. A day before yesterday, I was feeling a burning in my stomach, it was coming up. I started walking and drinking water again and again. After some time take medicine then felt better. The very next morning pain started again, then I'll go to the doctor, he told me this is GERD. "Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the tube connecting your mouth and stomach (esophagus). This backwash (acid reflux) can irritate the lining of your esophagus. Many people experience acid reflux from time to time." And the reason for this disease is ( fast food, junk food, cold drinks blah blah...). The doctor strictly advises me to avoid these things, you will get better soon. And I'm requesting you all to stop eating this unhealthy food.
