It could be so yes. I would say due to lacks in minerals balance and assimilation of nutrients from salt reduction etc. Also, CF's tend to have MANY pancreatic/Liver/Gallbladder and or GI issues as well, which can in turn, impact Thyroid and Hormones as well as Adrenal function. Antibiotics and some other medications can down regulate Probiota function too, so it depends on what she was given etc.
I work with people every day, via nutrition, overall wellness and genetic tendencies, and my own daughter is a carrier as well as my husband. I am amazed how many 'carriers' are symptomatic!
It took an active ground up approach for them both and still sometimes they have flares, but both are much better now from huge lifestyle and nutritional changes.
I hope your friend finds her answers to better wellness.
As an FYI, we ran complete hormones, GI, Metabolic and CBC diff panels for our daughter, as well as a Nutreval.
We cut out ALL processed foods, refined sugar and flour (use organic only), added enzymes, probiotics, and she went on an active GI protocol among other things.
