Pneumonia: Regular foods taste overly salty?

[GuavaGirl]

My mom is recovering from pneumonia and she was telling me that any non sweet food tastes disgustingly salty.  Any idea why?  Dehydration was my first guess, especially when she said she's only drinking about 4-5 cups a day, when I asked her.  

Any thoughts?

Was she prescribed any ABX to treat the pneumonia? I know when I took Biaxin (sp?) it completely altered my taste for a long time.
