  Gastroparesis is a syndrome of objectively delayed gastric emptying in the absence of a mechanical obstruction and cardinal symptoms of nausea, vomiting, early satiety, belching, bloating, and/or upper abdominal pain. […] The pathophysiology, etiology, and diagnosis of gastroparesis are discussed separately. […] Initial management of gastroparesis consists of dietary modification, optimization of glycemic control and hydration, and in patients with continued symptoms, pharmacologic therapy with prokinetic and antiemetics. […] Dietary modification is considered first-line therapy in patients with mild gastroparesis, although in clinical practice it is associated with only a modest improvement in symptoms. […] Foods that are fatty, acidic, spicy, and roughage based increase overall symptoms in individuals with gastroparesis. […] Diet should be low in fat and in nondigestible (insoluble) fiber; in general, soluble fiber or fiber that is cooked and reduced to small particle size by homogenization can be digested and emptied from the stomach except in the most severe patients with gastroparesis.

• #10 How is Gastroparesis Detected and Treated – Allied Digestive Health

  https://allieddigestivehealth.com/how-is-gastroparesis-detected-and-treated/

  Gastroparesis is a common stomach disorder, especially in people who have had diabetes for a long time. It occurs when the stomach cannot empty properly, making the food pass through the stomach slower than usual. This condition is thought to result from a problem with the muscles and nerves that control stomach emptying. […] How Is Gastroparesis Detected? […] Doctors begin by asking you about your symptoms and medical history. They also perform physical examinations like checking your temperature, blood pressure, heart rate, and any signs of dehydration and malnutrition. Besides that, they may also check your abdomen for tenderness, unusual sounds, and pain. […] To determine how fast your stomach empties its content, your doctor will use upper gastrointestinal (GI) endoscopy, lab tests, and imaging tests.

  Gastroparesis is a long term condition that often is seen in diabetes patients. Diagnosis is based on the knowledge of the possible underlying medical conditions as well as the concomitant medications and drugs that may lead to this condition. […] A detailed history of diabetes or other possible causes of gastroparesis is discovered. Family history of the condition is also important in case of inherited conditions leading to gastroparesis. […] Routine blood counts may reveal anemia or reduced red blood cell count and haemoglobin caused by malnutrition. […] Imaging studies include a barium X-ray. Here the patient is asked to swallow a liquid containing the chemical barium, which shows up on X-ray and allows radiologists to watch the passage of this solution through the digestive system via several serial images.

• #12 How is Gastroparesis Detected and Treated – Allied Digestive Health

  https://allieddigestivehealth.com/how-is-gastroparesis-detected-and-treated/

  Your doctor can perform urine tests and blood tests to diagnose gastroparesis. Urine tests are important in showing signs of infection, dehydration, diabetes, or kidney problems. Blood tests are used to detect signs of inflammation, dehydration, malnutrition, and infections. They also tell if your blood glucose levels are below or above the normal range. […] This procedure provides a visual examination of the upper digestive system, stomach, and duodenum, which is the beginning of the small intestines. It utilizes a long, flexible tube with a tiny camera at the end. Upper GI endoscopy can also diagnose other conditions like pyloric stenosis or peptic ulcer disease that may have symptoms similar to gastroparesis. […] Imaging tests help to show problems like intestinal obstruction or stomach blockage that could be causing your symptoms. There are two imaging tests that your doctor will likely perform: the ultrasound of your abdomen and the upper GI series.

  Other complementary tests to confirm delayed gastric emptying include thyroid function tests to rule out hypothyroidism, and hemoglobin A1c test (HbA1c) to estimate long-term blood glucose regulation in diabetic patients. […] The clinical practice guidelines for the management of gastroparesis in adults published in 2013 recommend restoring fluids and electrolytes and providing nutritional support, preferably through the oral route. […] Prokinetics are considered the first-choice medication to treat patients with gastroparesis, although evidence of its efficacy is limited. […] Metoclopramide was approved to treat gastroparesis by the United States Food and Drug Administration (FDA) in 1979 and remains the first-line medication for the treatment of these patients. […] The GES system has been approved by the FDA to treat patients who fail to respond or cannot tolerate medical therapy. […] The treatment of gastroparesis has two main objectives: to identify and treat its cause, and to treat associated symptoms.

• #14 Gold Standard Diagnostic Test Underutilized for Gastroparesis

  https://consultqd.clevelandclinic.org/gold-standard-diagnostic-test-underutilized-for-gastroparesis

  Gastroparesis is a gastric motility disorder defined by delayed gastric emptying in the absence of mechanical obstruction. […] Too often patients are being diagnosed based on symptoms alone, says Dr. Schneider. We believe combining a careful medical history with diagnostic tools, such as a 4-hour gastric emptying study, can help get an accurate diagnosis. It is also important to have tests to rule out organic causes such as esophagogastroduodenoscopy and imaging studies that may include double-contrast gastrointestinal radiologic series. […] Gastric emptying scintigraphy (GES) is a nuclear medicine imaging test used to measure the rate of gastric emptying and is considered the gold standard to establish the diagnosis of gastroparesis. […] While not the only test used in the diagnosis of gastroparesis, it is the most definitive and easily accessible test, Dr. Schneider says. Other tests that are available are gastric emptying breath tests and wireless motility capsule.

  Nausea and vomiting are symptoms of several other digestive disorders. After taking a complete medical history and performing a physical examination, your doctor will ask for some additional tests in order to determine a diagnosis. […] Patients who suspect that may have gastroparesis can expect to undergo diagnostic testing including: […] Gastric Emptying Test (GET) This procedure measures the speed at which food empties from the stomach into the small intestine. The GET, considered the most accurate way to diagnose gastroparesis, requires that you eat a meal in which a solid food (usually eggs or oatmeal) contains a small and safe amount of a substance that will appear on a medical scan. A scanner is placed over the abdomen to monitor the foods movement through the digestive tract.

• #18 Diagnosis & Tests – About Gastroparesis

  Gastric emptying scintigraphy (GES). The doctor will request this test to see how your stomach is emptying. The nuclear medicine department usually does this test. The doctor or nurse will ask you to consume a solid meal (usually scrambled egg with bread). This contains a small amount of a radioactive substance, called an isotope. The isotope has a very short half-life, so it disappears from the body rapidly. External cameras called gamma cameras track the progress of the meal. […] Some medicines affect the results of the test. These should be stopped before doing the test. Some examples are opioid based medications such as codeine, tramadol, morphine, buprenorphine, tapentadol and fentanyl. Do not stop your medicine without discussing it with your doctor first. […] This test can also show abnormalities when people have a diagnosis of functional dyspepsia. There is not an exact relationship between the test results and symptoms.

  How is gastroparesis diagnosed? A healthcare provider will ask you about your symptoms and health history, including conditions and procedures that can cause gastroparesis. Theyll use imaging tests to look inside your stomach to make sure theres nothing physically obstructing it, which might cause the same symptoms. If they don’t find an obstruction, theyll follow up with gastric motility tests, which evaluate your stomach muscle activity. […] What tests are used to diagnose gastroparesis? The first step is having imagining tests to rule out an obstruction as the cause of your symptoms. These tests could include: Upper endoscopy. Upper GI series. CT scan. MRI. Abdominal ultrasound. […] If there is no physical obstruction, the next step would involve gastric emptying studies to measure your gastric motility. These could include: Gastric emptying scintigraphy (GES).

  Some people who have problems with heartburn, bloating and pain in the upper abdomen after eating may be suffering from a condition known as delayed gastric emptying, or gastroparesis. […] Patients and doctors often assume the symptoms of gastroparesis are reflux or other gastrointestinal conditions. This means it may take a long time for someone to be diagnosed correctly, Dr. Langman said. Diagnosis may include tests to measure stomach emptying. In one test, called a gastric emptying scan, the patient eats a bland meal such as eggs or oatmeal, which contains a small amount of radioactive material. A camera outside the body scans the abdomen to show where the radioactive material is located. By tracking the material, the doctor can measure how fast your stomach empties after a meal.
