9) A sour taste
Stomach acid is not a sweet substance to taste — quite the contrary. The excess of gastric juices that constantly flows to the throat area sometimes reaches the back of your tongue and may even go further. It does not only stimulate your papillary buds while acid is around, but may also start to change your perception of taste after a while. Thus, people start to feel a sour taste, especially when other symptoms are at their peak, as in heartburn, sore throat and coughing.
However, keep in mind that several medications may cause alterations in your taste, so leave the diagnosis to a health professional if you are having the symptoms we have described in this list. Experiencing a sour taste with heartburn, coughing, and problems swallowing in a single patient is suggestive of gastroesophageal reflux disease. However, your doctor may still need to perform various tests because even if we suspect the disease we need to know where it is coming from and how severe it is affecting your gastrointestinal tube.
