Ditto, ditto, ditto, I have had low normal body temp for years, usually between 96.5 and 98. When I get to 99 I am really ill. It is hard to convince the health care providers that 99 or 100 is high for me. When they see labs out of whack then they finally believe me!!!
This past 6 months I have run at least 100 temp every day, not all day but at least during part of the day, this is how I know I have some flaring going on. I have been on pred. since June after my first hosp. visit and am still on 10mg.
Up until the crohns took hold of me back in '99 I for the most part was always warm or hot. My temp was normally 99 to 99.5 degrees and I rarely needed a jacket even in the winter (Of course I live in Florida so that helps)
But ever since the crohns hit I have noticed that I get cold very easily ...and where B.C. (before crohns) my wife would ask me to hold her hands or rub her feet because she was cold and my hands were always warm.....now my hands and feet are always cold. I seek her out because she has warmer hands. My body temp now averages 96 to 97.
Part of this may be caused by the loss of my body fat and muscle. For some strange reason my blood pressure has also dropped through the floor. BC my blood pressure was on average 110/120 over 80/85 and now I am usually about 100 over 65 or 70. My pulse rate as well has dropped an average of about 10 beats. So I figure if the blood isn't coursing as fast I am going to get colder easier.
My guess is that there are several mechanisms at play that affect our ability to control our body temperature, in addition to heat generated by inflammation in the core of our bodies.
Sorry this post got so long. May quality of life be on our side, and remissions come for us all in this New Year and beyond!
