The notion that type 2 diabetes is caused by a 'corrosive parasite that blocks the pancreas and prevents insulin production' does not pass the fact check on any level," Professor Thomas said.
Type 2 diabetes mellitus is the result of skeletal, liver and fat cells resisting the attachment of insulin, not reduced insulin secretion. That is Type 1 autoimmune diabetes mellitus. In the early stages of T2DM insulin levels are higher than normal.
It gets worse,
'corrosive parasite that blocks the pancreas.The endocrine functions of the pancreas are in clumps of 5 hormone secreting cell types that secrete 6 glucose regulatory hormones directly into the blood supplly. The islets of Laangerhans make up about 2% of pancreatic mass. The rest is producing and routing digestive enzymes to the duodenum. A blockage of these ducts results in painful acute pancreatitis.
Acute edematous pancreatitis is a medical emergency characterized by a sudden pancreas inflammation. It can be caused by various factors, primarily gallstones, alcohol consumption, or medication. Acute edematous pancreatitis caused by Fasciola hepatica* infection is exceptionally rare and could be overlooked.
