@nazleer, I'm not familiar with diabetic digestive neuropathy but did find an older research article that sounds similar:
--- Diabetic neuropathy in the gut: pathogenesis and diagnosis: https://link.springer.com/article/10.1007/s00125-015-3831-1

Is it a form of an autonomic or sensory neuropathy associated with diabetes? Didn't your doctor discuss possible treatments after you were diagnosed?
