Flavour Metal Core What Could Cause A Person To Taste Metal, And Become Nauseous, Every Time They Drink Water?

What could cause a person to taste metal, and become nauseous, every time they drink water? - flavour metal core

One of my friends said he hates water, because you like the taste of metal flakes in it and makes him want to pass. He drank the water is filtered through a Brita filter and it still tasted of metal. He became sick and ice seemed to calm his stomach. I asked if he had the same problem of water source, said that he knew ... He complained before about this problem, if he can afford to pop or other flavored drinks. I thought he was just exhausting, but tonight, when he was sick (after drinking Brita-filtered water) was very sick (nausea) ... He said the water was sitting on his right lower abdomen, upset stomach ... Previously, he said, the water was sitting on his chest? You know (that feeling that something is not all the way down and on his chest, neck?) I wonder what could cause this problem? Is this a problem with tap water? Brita-filter should get rid of a metallic taste, is not it? Or could it be otherwise? For example, a diabetic. But he said that metal taste WHENo drinking water, not all the time ... So what's the problem? I appreciate any ideas / help / advice anyone can give. Thanx.
