In two weeks we are doing a 'double balloon enteroscopy' - put a scope through the entire small intestine. Hopefully that will prove more definitive. There are other tests before that - very involved and various preparation procedures. It is a bit tiring and requires all of us to work together to not miss or confuse anything.
Another possibility is a gastro neuroendocrine tumor although there are only markers so far, nothing definite. The balloon procedure should clarify that possibility. My time is almost fully involved with details but I have been trying to get this done for years and with my last two emergency hospital visits I changed GI Drs. So finally I have a team to face a challenge that has pressed me harder and harder for at least 25 years.
