Maria must be suffering from cystic fibrosis because all the given symptoms are symptoms of this disease. There might be other symptoms that her parents might have missed.

Wheezing, salty skin and low weight gain etc are the most evident symptoms of cystic fibrosis. Cystic fibrosis is a genetic disorder that is inherited in an autosomal recessive manner. The disease mainly affects the lungs but it can also affect the liver, pancreas and kidney.

Sweat test and genetic testing are some of the diagnostic methods of cystic fibrosis. Greasy bowel movement is also a symptom of cystic fibrosis which Maria's parents might have missed.
