WebMD explains gastroparesis, a stomach problem associated with diabetes. DIABETIC GASTROPATHY. An association between delayed gastric emptying and diabetes was known for more than half a century and in , Kassender. Diabetic gastropathy is a term that encompassesa number of neuromuscular dysfunctions of the stomach,including abnormalities of gastric contractility, tone, and.

Evidence for a role of nitrergic nerves was already obtained in early studies that demonstrated that nNOS knockout mice developed a dilated stomach with hypertrophy of the circular muscle layer.
In parallel, our understanding of neuropathic pain and visceral hypersensitivity has improved substantially over the last decade. The goal of treatment of diabetic gastropathy is not only to prevent morbidity by controlling gastrointestinal manifestations, but also to enhance glucoregulation and, thus, better control the basic diabetic process.
If a patient with diabetes has lost control of his or her glucose management for no apparent reason and has no gastrointestinal symptoms, it is nevertheless important to evaluate the possible causes for a digestive or absorption problem that could be upsetting the glycemic balance.
The Diabetic Stomach: Management Strategies for Clinicians and Patients
Population-based data on DGP are limited. It will also minimize the effects of glucose toxicity as well as forestall further damage to autonomic nerves of the gastrointestinal tract. DGP can cause a wide variety of symptoms.
Gastropathy can contribute to bezoar formation and intestinal obstruction, ulcer development, acute gastric dilatation during ketoacidosis or after endoscopy, incapacitating vomiting, respiratory aspiration, and dehydration. Have you had any changes in appetite recently?
Although similar changes were also observed in idiopathic gastroparesis patients, a significant correlation was lacking in this group; this may reflect the fact that idiopathic gastroparesis is likely a much more heterogenous disorder than DGP, with a less well understood pathophysiology and may include patients with severe functional dyspepsia.
The breath is sampled at regular intervals and measurement of 13 CO 2 is used to calculate an emptying curve. The relation between elevated blood glucose levels and gastropathy symptoms should be pointed out and emphasized. Diet and glucose control also are important in the management of diabetic gastropathy.
This risk will often lead patients to dose insulin mid-meal or even after the meal, leading to further poor blood glucose control. Gasrtopathy features of idiopathic gastroparesis vary with sex, body mass, symptom onset, delay in gastric emptying, and gastroparesis severity. Oxidative stress can be caused by increased reactive oxygen species and loss of antioxidant protection such as heme-oxygenase-1 HO-1 that is up-regulated during oxidative stress.
In recent years, we have gained much insight into the pathophysiology of DGP, in addition to increased awareness of the disorder.
The vomiting may occur at any time. Laboratory Testing In ruling out nondiabetic causes or exacerbations of gastropathy, complete blood count, chemistry profile, electrolytes, and gastropwthy testing should be performed, as well as thyroid evaluations.
Exclusion of gastroduodenal obstruction, such as by gastric cancer or peptic ulcer disease, requires gastropahy. Gastroparesis is a serious complication of diabetes mellitus DMdefined as a delay in gastric emptying without any mechanical obstruction in the stomach.

In general, diabetic enteropathy occurs in parallel with other forms of diabetic neuropathy, whether peripheral, autonomic or both.
In Consultations in Gastroenterology.
Is the antidepressant venlafaxine effective for the treatment of functional dyspepsia? Acta Med Scand Gastropathy may be underrecognized gastgopathy clinical practice because the symptoms, diabetlc present, are nonspecific.
A single-blinded, sham-controlled trial of electroacupuncture in DGP patients significantly reduced symptoms and accelerated gastric emptying, and symptoms remained improved 2 weeks after the treatment. A differential diagnosis algorithm should be followed to determine whether the patient has early or asymptomatic diabetic gastropathy that is interfering with a previously effective treatment regimen.
Conclusions from a case study.
Pathophysiology and management of diabetic gastropathy: a guide for endocrinologists.
This test is well validated, simple to administer outside the hospital setting and is relatively inexpensive. Patients may require more than one agent and may require cycling through a number of agents to find optimal response. A validated score for measuring DGP symptoms has been developed for use in research settings. Completion gastrectomy seems to provide symptom relief in postsurgical gastroparesis, but benefits of gastric surgery for other forms of gastroparesis are not adequately studied.
The Asymptomatic Patient As discussed earlier, hypomotility, manifested in the stomach as delayed emptying, may interfere with the absorption of oral medications and can lead to further hyperglycemia, which in turn may promote greater autonomic nerve damage in the digestive system and continue the cycle until damage is demonstrable and symptoms are evident.
Patients should be advised to avoid exercise during periods of poor metabolic control, however, because blood glucose may actually rise rather than fall.
Although other methods for characterization of gastric function have been described including antroduodenal manometry, ultrasound, MRI, gastric barostat and electrogastrographythese either have not been validated or are not generally available outside of research centers.
DGP may frequently be associated with other manifestations of diabetic enteropathy elsewhere in the gastrointestinal tract. A deficiency of gastric interstitial cells of Cajal accompanied by decreased expression of neuronal nitric oxide synthase and substance P in patients with type 2 diabetes mellitus. Djabetic frequent blood glucose monitoring before and after eating.
