Check your thyroid - an overactive thyroid can change your taste
u can also have asthma. people who have ashtma that isnt under control or arent aware get severe horrible metalic tastes in there mouths. i wonder, do u have ne signs that show asthma?
It can also be a bile reflex into the stomach
Acid reflux does cause this, but I wanted to add that my mom had a similiar problem due to her thyroid. She has hypothyroidism and it casued a bad taste and smell in her mouth just like you described. It was like a tin/metallic smell and taste. She desn't have this problem now her thyroid condition is under control with synthroid.
YOU COULD ALSO HAVE ACID REFLUX. IT DOES CAUSE A VERY ICKY SOUR, METAL TASTE IN YOUR MOUTH AMONG ALOT OF OTHER SYMPTOMS.
Hello,
I would see a Gastroenterologist. The last time I had Metal Mouth I had an active ulcer.
