My husband has been unable to eat hardly anything for the past couple of weeks because he says everything tastes bad. Even things he has always liked now have a bad taste and he cannot eat them. This started awhile back but at first it seemed to be more related to smells. His sense of smell seemed especially sensitive. If he smelled something, then he couldn't eat it - even though the smell was not bad. Now it has evolved to the point that most everything tastes wrong to him and he just cannot eat it. It isn't that he can't swallow, he just gets nauseous if he puts the food in his mouth. Any suggestions? He takes a variety of mediations for heart issues but he and his physician have been temporarily stopping each of them for a period of time to see if there is a correlation between one of them and the bad food taste - so far no success in this.
