Hello
There is a misconception that in
typhoid fever only boiled or hot things should be given diet . This is misconception and myth .
One more thing in rural area that Intravenous drip or glucose ( as you mentioned in your query )is a cold thing or cold remedy .
Let me explain that intravenous drip contains glucose, ( dextrose ) in various strength, saline , mix , elctrolyte-M , invert sugar , plasma expander etc.
This type of fluid is given for many purposes as when doctor don't want oral medicine ( for fear of
vomiting etc).
Typhoid ( as you mentioned ) is an
intestinal disease and water born infection caused by
Salmonella A B AH OH ( four strain).
So Get in blood examination for
Widal test ( typhoid confirmation test ) , serology test for typhoid fever.
If your treating doctor advised Intravenous fluid ( glucose ) get it at once .
Complete treatment is important in this fever.Usually the course of typhoid is 5 days ( now a latest treatment ) while it is 14 days - 28 days according to antibiotics used.
Good luck.
