Our 2 1/2 year old boy is DD with Autistic tendencies. He also has hypotonia. Here is my question: If your body cannot break down proteins (like casein & gluten), would that cause hypotonia? (Low muscle tone) Any ideas would be great!
Re: Hypotonia and inability to break down proteins
Hypotonia is not uncommon in celiac disease, where the body has an autoimmune reaction triggered by gluten. I think it is more of a neurologically-related hypotonia than a hypotonia due to inadequate protein. Celiac disease is more common in autistics than in the general population. Hypotonic celiacs do benefit from gluten-free diet. Both celiac disease & autism have a "leaky gut" common denominator.
I'm sorry that my answer skirts your question about causation. I'm guessing that if there is a digestive problem (low stomach acid and/or low digestive enzymes) that is affecting ALL proteins (esp. meat), maybe muscle development would be slowed. There may be some sort of stool or blood test available to show whether protein is being digested & getting into the blood stream.
