people who are not eating right and exercising are more susceptible to head colds and those bouts last longer and are more likely to result in complications such as pneumonia or bronchitis or sinusitis etc. compared to people who eat right and exercise regularly. this general principle is especially true for people with diabetes (type 1 or 2) because their bodies respond particularly well to lifestyle efforts and they are particularly "penalized" when unable to eat right or exercise. diabetes is very unforgiving this way. the immune cells (white blood cells) are particularly sensitive to improvements (or worsening) of blood sugar control. they are among the first bodily functions to improve when the glucose control does. this probably translates into rapid reduction in risk for colds and other infections in someone who finds a way to make lifestyle changes. i believe you would not be surprised to hear an answer like this one and i know you would like to make such changes. we all recognize it is hard to do and takes advanced planning and an organized approach.
is it true that people with diabetes are more likely to catch colds and the flu?
