A distressed thyroid is probably at the root of a GI motility problem. But then so are neurological disorders. Not to mention autoimmunity, in particular Scleroderma. (citations below)
Three different systems, three different causal factors converging on one problem, motility.
There's a simple solution, to such complex problems.
We need to first admit to the possibility. Think of any one problem you face, and you can easily figure out how more than one system is implicated. Common sense tells us that hormones, nerve tissue, immune organs and even musculoskeletal and dermal tissue are all at play. That being the case, a method that encompasses all the possibilities is more likely the best option.
An excellent solution is a bioenergetic healing modality.
With a bioresonance test all organ stress, and any agents involved, can be confirmed and then treated simultaneously, as the body in fact functions to address any one particular condition, like GI motility. That's both comprehensive and specific. There's no telling how in missing one component if the condition will be corrected.
The passages below explain how motility incorporates many systems. that ultimately coincide in the case of many other disorders. This is but one example.
"The gastrointestinal manifestations of thyroid disease are generally due to reduced motility in hypothyroidism, increased motility in hyperthyroidism, autoimmune gastritis, or esophageal compression by a thyroid process. Symptoms usually resolve with treatment of the thyroid disease." (endocrine tissue) https://www.ncbi.nlm.nih.gov/pubmed/20351569
"Neurologic diseases can affect the bowel at several levels of innervation--by altering the electrical activity that controls smooth muscle, the enteric nervous system, or the extrinsic neural pathways to the gut." (nerve tissue)
" Dysmotility of small intestine may cause chronic pseudo-obstruction. Scleroderma can decrease motility anywhere in the gastrointestinal tract." (SIBO and autoimmunity)https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3150032/
