@bree11 Here is some very basic information about MALS: https://my.clevelandclinic.org/health/articles/median-arcuate-ligament-syndrome-mals
There are a few good papers on MALS geared toward the medical professional also, wish there more! There needs to be more awareness done on this condition. Have your doctors considered a GI motility study? For me most of my GI work up came back normal, I had a some motility issues but not significant enough to raise eyebrows. It is a long diagnostic road, but worth taking in the end. If the tests get too much, let the doctors know. Sometimes I needed to take a month off of testing just to get away from the hospital awhile. (With my doctor's permission). I was fortunate that my Mayo team really believed in shared decision making. The fact you found a doctor that is willing to look further into MALS is priceless! That says a lot, and you may find that you may be guiding your care and teaching more than you expected. Don't be afraid to tell him what you have learned.
