Hello and thanks for your post

I'm sorry to read about what your dad is going through and I appreciate that this is a worrying time right now.

Chemotherapy can weaken the immune system making it easier for infections to develop, and it can be harder for the body to fight them off. Even when blood tests come back okay, sometimes infections don't show up right away, or it may take time to pinpoint where it's coming from. It sounds like your dad's doctors are trying to establish the cause and it's good that he is being monitored in hospital.

His stomach problems like not being able to keep food down could be related to his infection or chemotherapy or a combination of both.Hopefully once your dad responds to his treatment and his temperature comes down he should feel better soon.

Please get back to us if you need any more information or support.  You may find it helpful to talk things through with one of the nurses on our helpline.  The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.

Kind regards,

Celene
