Hey all,

I've written a 100,000 word science fiction novel for young adults and, despite me having to accept some scientific holes I'm determined to maintain a degree of accuracy in the edited/finished product. With this in mind what would happen to the digestive system if all the nutrients required for a human to survive were put into the body intravenously? In this scenario the people applying to this method of feeding would not drink water or ingest food in the normal way. Would the digestive system become dormant? Would it become infected or swollen? Any replies would be helpful!

Thanks!

Interesting question. I've not ever had the need to think about this question before but this is a particularly interesting issue with regards to patients who have survived a critical illness.

If a patient is seriously ill on intensive care or just after significant gastrointestinal surgery, nutrition is usually provided by parentral methods (IV route) and this poses a problem called 're-feeding syndrome' which is a potentially serious issue if oral food and liquid intake is not re-commenced in a controlled way so it is worth looking that up.

Most of the patients on long term TPN (IV nutrition) are on it because their bowel isn't working for whatever reason - either acutely in ICU or long-term because of things like Crohn's or short gut syndrome following surgery. So I'm not really sure what would happen if you gave it to someone with a normal gut whilst not allowing any oral intake.
