Why is there a persistent low-grade fever in a 54-year-old female?

Question

Hello doctor,

My mother is 54 years old and is facing persistent low-grade fever. She had it for almost a year and nothing was diagnosed from the tests and then suddenly it got fine. Now again she got a fever from some stomach infection and it has been 15 days that the fever is there between 99 to 100 degrees. What could be the possible reason?

Please help.

Hello,

Welcome to icliniq.com.

Did your mother undergo urine culture sensitivity test? Because many of the postmenopausal or perimenopausal women suffer from urinary tract infection that is chronic and drug-resistant due to urinary leak and urinary urgency. Low-grade fever can also be there due to chronic infections like tuberculosis. So, if a chest X-ray is not done, I suggest you to get an X-ray. Lymphoma or lymphoid malignancy can often be missed as a differential diagnosis of low-grade fever. At last, some autoimmune diseases can present with a similar type of low-grade fever and diffuse musculoskeletal pain. If there is pain associated, get a blood test done for ANA (anti-nuclear antibody).

I hope this helps.
