Sarah, honestly, I have never heard of anything like that.
My daughter had cramping, diarrhea and belly pain when we first started the NJ tube - that is called feeding intolerance and it was just because she was not used to eating and her intestines were not happy with the formula. But that gets better in a few days - we used Levsin till it got better and very slowly upped the rate of the feed.
The only other thing I can think of is Refeeding syndrome - that can cause tachycardia, electrolyte issues (usually phosphate and potassium) and fatigue and nausea. My daughter also had that the first time we used an NJ tube but I'm not sure if that's what you had since you were getting feeds through the NG before this, right?
My daughter had not been using her NG tube (she kept throwing up) and she was so underweight and malnourished that her body just could not handle the extra calories.
I honestly don't know - I would ask about both things, though neither fully explains what you went through. I know you are pretty malnourished too, so perhaps it was Refeeding Syndrome even though you had been on the NG feeds?
The only other thing I can think is a reaction to sedation (if you had any) when they placed the NJ tube. Were you given anything for that? Here NJ (and GJ and J) tubes are placed with sedation usually (for both kids and adults).
It does leave you in a tough spot, if you cannot tolerate the NG tube feeds or NJ tube feeds. I guess the only other option is TPN, which is far from ideal.
I am SURE you do not want to repeat that experience, but I wonder if it would be worth trying the NJ tube again in the future. With very, very slow feeds - work your way up from 5 mL/hr.
Did they check the placement of the NJ tube when you were in the hospital? Because vomiting can often displace it - so it ends up back in the stomach.
What formula are you using? Was it the same one you were using when you had the NG tube?
I honestly have no idea, Sarah, I've never heard of anything like this. Sorry
