Bowyer joined Blues from West Ham United in January and is looking to help the club earn promotion back to the Premier League.
The 32-year-old is out of contract at West Ham in the summer and has been tipped to sign a permanent deal at St Andrew's.
However, the former Leeds United man wants to focus on Birmingham's promotion push, rather than worrying about his own situation.
"I'll have to weigh up my options and go from there, but at the moment I'm not even looking that far forward," Bowyer told the club's official website.
"I'm looking to do what I came here for and that's to help Birmingham get into the Premier League.
"I am enjoying it here and I still feel as though I've got a lot to give. I'm still getting box-to-box and I've played regularly so fitness wise I'm fine."
