My husband was admitted Sun evening because of the flu, dehydration, heart rate high and high fever...they have been administering fluids every 2 hours. He s a type 2 diabetic and has high blood pressure.His vitals are normal, Ekg was normal..no signs of heart issues. Some damage to kidneys but not serious...now here s the problem..His enzymes are in the 6000 s....the nurse said it s possible to have elevated enzymes if your a person who works out strenuously. My husband has been coughing extremely hard since Friday..she said it could be possible that the coughing is causing the enzymes to rise. I personally never heard this. Is it possible? his fever is running now around 99-100 on Tamiflu, antibiotics and his normal doze of meds for diabetes and blood pressure.
