Hi - my daughter is going to be 5 yrs old in July. She is small for her age, eats like a pig and every half hour or so and is gaining weight slowly but surely. She has had over 12 months of chronic diarrhea with no known cause (dr says diarrhea prominent IBS)(stools are pale, bulky and tons of gas and bloating). She does have a history of chest colds and chronic phlemy coughing but not severe enough to really raise red flags. She simply goes on puffers from time to time to help clear the wheeze. Last week, as a last resort, Dr. ordered a sweat chloride test which took half an hour! We are still waiting results but I am so worried. She has other minor developmental delays and behaviour issues too! We are now noticing our 1 yr old son developing chronic diarrhea(2 months now off and on) as well and he has been diagnosed with cold related asthma and is often taking puffers. I do not notice anything more than a slight salty taste to either of their skin. Do you think I should have our son tested even inf my daughers results are negative or am I just being an over protective mom? Can someone have CF and not be diagnosed until 5 yrs of age? We have no known family histoy either.<img src="i/expressions/face-icon-small-confused.gif" border="0">
