I have Scleroderma also and have several of the symptoms you suggested. I have been told by my doc that the reason that we have such stomach problems is one: esophagus problems which cause severe acid reflex (Is she on any meds for this? I take protonix and it works great! They also say to elevate head of bed, do not eat before before bed....etc) two: scleroderma affects intestines causing them to slow down. I take B12 shots which they say help that! I did have the cronic diarhea also but once I started taking the protonix and b12 shots, it went away.
