What Causes Metallic Taste When Coughing?
Hi Northernlights3873,I know you posted your question a long time ago and you most likely received an answer from your doctor (the only one who can accurately diagnose the problem), but I would love to hear an update.
There are many causes for a metallic taste in the mouth which is why doctors generally examine the patient for other symptoms in addition to this one. It could be as simple as an irritated throat that has a little blood in it to many other possibilities. Here are some causes for this taste (the underlined ones are hyperlinks that will take you to more information on that topic):-Side effects of medications-Allergies
-Excess consumption of seafood-Exposure to certain chemicals-Infections in the mouth/teeth-Chronic sinusitis
- Hyperparathyroidism -Renal abnormalities-Nutritional deficienciesI do hope all is well!
