I recently took my 4 year old to her pulminoligist for a routine exam and he expressed his concerns of her having CF. I have never heard of this and I am very uneducated about lung disorders and diseases and having a hard time figuring anything out online. My child has not digestive problems but was diagnosed with Asthma at 10 months and has been coughing every night for about 2 years until the point of vomiting, this is in the sitting up and laying down position. She has been on so many different medications for her cough and medications to help her lungs function properly but has never had any digestive problems besides having acid reflux and has had no problems gaining weight. Someone, anyone please give me your insite. They are going to do a sweat test in december but i find it hard to believe she could have had this for 4 years and gone undiagnosed.
