My 2 year old son has had health issues since birth. At 4 months he was diagnosed with GERD, then at 6 months he was hospitalized over night with RSV. From 4-6 months he maintained a weight of 15lbs until I switched formulas to Alimentum. He then gained weight, but was dealing with constipation so was put on Reglan in addition to the Prilosec for the GERD. Around a year old he started having diahrea daily, so we took him off of the reglan. This lasted about a month, then back to the constipation. At 1 year 8 months he had a gastric emptying study done which showed delayed motility. He's now on: Prevacid, Flovent, Reglan, Miralax and Erithromyicin in order to keep the GERD and the constipation away. HOWEVER he still battles with constipation. Within a single day he can go from a super runny diaper (due to the meds) to one that's hard as a rock, causing him to scream in pain while he goes. We switched GI doctors since the original one was continuously wanting to wean him off of the reglan/prevacid. The new doctor, determined to get to the cause of this had a sweat chloride test done to rule out CF.
My son's first test came back with a 74. Then the doctor ordered another sweat chloride test along with a fecal elastace and a fecal fat spot test. This second sweat test came back with a number of 36!!! We're still waiting for the results of the stool studies.
While they were trying to rule this out, I started to do a lot more looking into the symptoms of CF. My son has had 2 respiratory illnesses causing him to be on the neubulizer (one hospitalization), however he also tends to get any cold that he comes into contact with. He continues to have bouts of constipation despite the medications that he's on. Most of the stools are a very light tan almost yellow in color (TMI, I know...) and are very stinky. If they're not little pebbles, or baseball sized, they're very thick, yet runny if that makes any sense.
I'm not sure what to think at this point in time. The pediatrician says that with this second test being negative, that if the stool studies are negative, then he doesn't have CF. My thoughts are, what about this first test??? and is it common to see such different results between the 2 tests? Lots of questions....
Thanks for reading!
