Gastroparesis or Delayed gastric emptying is caused by a number of reasons.
For instance, Gastroparesis or Delayed gastric emptying may be of three types:
Transient gastroparesis (one which stays for only a short time) may arise in acute illness(connotes an illness that is of short duration, rapidly progressive, and in need of urgent care) of any kind, with the use of certain cancer treatments or other drugs which affect digestive action, or due to anorexia nervosa, bulimia and other abnormal eating patterns. In simple, in transient gastroparesis, the Vagus nerve stops functioning properly for some time, resulting in imperfect stomach contraction and slow food movement to intestine; but after some time the Vagus nerve starts functioning normally, resulting in normal gastric emptying.
Chronic gastroparesis may arise frequently due to autonomic neuropathy. This may occur in people with type 1 diabetes or type 2 diabetes. Years of high blood glucose or simply by having diabetes for a long time, damages the vagus nerve, resulting in gastroparesis.
Chronic gastroparesis may also occur as part of a mitochondrial disorder.
Chronic Gastroparesis condition has also been associated with various connective tissue diseases, such as Scleroderma and Ehlers-Danlos syndrome, and neurological conditions, such as Parkinson’s disease.
Chronic gastroparesis can also be caused by other types of damage to the vagus nerve, such as abdominal surgery.
Idiopathic gastroparesis is the gastroparesis caused by no known cause. About a third of all chronic gastroparesis cases have idiopathic nature.
For instance, many persons show gastroparesis symptoms after an acute viral infection. Researchers believe that many of these cases are due to an autoimmune response triggered by an acute viral infection. “Stomach flu”, mononucleosis, and others have been anecdotally linked to the onset of the condition; but since no systematic study has proven a link, hence such cases are put under Idiopathic gastroparesis.
