@ZipLine-- Constant heartburn symptoms can also be a sign of a bacterial infection in the digestive system.
We have both good and bad bugs in our stomach and digestive tract. Sometimes, when our immune system is weakened or after use of antibiotics, the good bacteria can be wiped out. If the number of bad bacteria outweigh the number of good bacteria, it can cause all sorts of digestion problems like upset stomach, stomach cramps, acidity, heartburn, diarrhea and so forth.
It's always a good idea to get tested for bacteria when these symptoms become constant. And it's so easy to get tested nowadays. They have breath tests that quickly and easily identify bacteria in the digestive tract.
