What causes low-grade fever with weight loss and bone pain?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

My mom, aged 45 years, has had a fever for almost two months. The temperature used to vary from 194 to 212 degrees Fahrenheit at night and gradually comes down. She was weighing 231 lbs, and now she is 194 lbs.

Now, she is having bone pain and a light feverate night when there is pain in the bone. She has been advised to take calcium and iron tablets. She is also getting her regular periods. Menopause has not reached yet.

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

The fact that she has been having a fever off and on for the last two months, and is a low-grade fever, especially in the evening,h accompanied by weight loss and bone pains, indicates a possibility of tuberculosis infection.

It is better to get her Mantoux test and ADA (adenosine deaminase) levels done to rule out the same. As she has been in a colder country, the possibility is unlikely.

If she has been staying with you for more than six months or if she has recently visited you two months back, then there is a possibility of her having contracted the infection earlier in her country, and she carried it with her.

Keep her well hydrated in the meantime, and start multivitamin tablets daily to increase her appetite, which may have also suffered a loss for the last two months.

I hope this helps.

Please follow up with the reports.

Thank you.
