Hello
welcome to health care magic
Thanks for your query
Your mother is 45 yrs old and since 9 yrs she is diabetic,,and she is on
regular insulin...
Normally insulin is the only hormone to fight against increased blood glucose levels..but in the case of
diabetes insulin levels are either low or absent and for this either hypoglycemic agents like
metformin or insulin is required..
In the case of physical stress like fever,infection in the body,or any trauma several hormones like
epinephrine,
cortisol, come into action to counter regulate stress,,and in turn they increase the glucose levels..
In normal persons insulin secretion is increased to control the glucose levels..
But in diabetic individuals the dose of insulin should be increased...
In your mother's case presence of fever and vomitings is a stress condition..and needs higher dose..
First of all control the fever causing infection.
Consult general physician for more suggestions..
I hope I have succeeded in providing the information you were looking for.
Thank you
