Approximately 5-6 Weeks Ago I Noticed Every Smell Is Exaggerated

Approximately 5-6 weeks ago I noticed every smell is exaggerated to me. I smell the dish detergent when near the sink, smell the metal of the stainless steel sink, etc. Food doesn't taste as good as it did before either, so I eat a lot less which isn't good because of my low weight. Living in a large apt. bldg. I smell so many different food smells. It is just awful to live with.
