I am a 22 year old female and I had my gallbladder removed about 2 weeks ago. Things have been going relatively normal - I eat all lowfat and stay away from what I need to in order to keep the post-op experiance the way it should. Stranger thing is, though, is that lately I keep getting these terrible heat 'flashes' that makes me feel like I'm burning up from the inside out, I get bad headaches and occasionally I feel like I may pass out. The weird thing also is that when I take my temperature it's relatively normal from between 97.6-98.5, never really over. It's so strange! I even break out into a sweat and even if I have the air on me at full blast with cold, I still can't cool down. And when I'm not boiling up, I freeze. It's like I can't get my temp to regulate at all. Could this be a symptom of post-op gallbladder removal surgery? Or is this something I need to be concerned about? Please help so I know if I need to seek help from my GI doctor or not. Thank you.
