Indigestion
Most people will experience symptoms of indigestion at some point in their life and it's usually nothing to worry about, however the symptoms you experience can feel quite unpleasant. From heartburn to feeling sick and bloated, to farting and burping and bringing up food or bitter tasting liquids in your mouth. Sometimes these symptoms can be treated with dietary changes such as drinking less tea, coffee or alcohol however sometimes medical intervention is required if the symptoms become a little too unbearable in which case your doctor or pharmacist may prescribe antacids or proton pump inhibitors.
