What Causes Weakness While Doing Daily Activities?
testing may help
Detailed Answer:
Hello,
although a urinary tract infection is a serious one, your father should be tested for various disorders to make sure there is nothing else going on besides normal weakness that follows serious infections. His response to antibiotic treatment can be evaluated (besides clinical evaluation) with CRP testing. CRP is an inflammatory marker. When a patient has an infection, the CRP rises fast. Proper treatment makes the CRP fell equally fast.
An ultrasound scan should be done to make sure there is no obstruction, which may cause various problems including persistent infections (despite the negative culture result).
Finally other tests may help to exclude causes like hyponatremia (serum sodium), potassium disorders (serum potassium), anemia (complete blood count), uremia (urea and creatinine).
If all the tests are negative then the patient probably needs some more time to feel better.
I hope it helps!
Kind Regards!
