The American Journal of Gastroenterology (2007) 102, S271–S426; doi:10.1111/j.1572-0241.2007.01491. Gastroparesis is a digestive disorder in which the motility of the stomach is either abnormal or absent. In healthy people, when the stomach is functioning normally, contractions of the stomach help to crush ingested food and then propel the pulverized food into the small intestine where further digestion and absorption of nutrients occurs. When the condition of gastroparesis is present the stomach is unable to contract normally, and therefore cannot crush food nor propel food into the small intestine properly. Normal digestion may not occur. Strange question, huh? Before you get too excited, I’m not about to tell you that a low carbohydrate diet is a remedy for back pain. Instead, I am going to explain. Multiple sclerosis can cause a variety of symptoms: changes in sensation (hypoesthesia), muscle weakness, abnormal muscle spasms, or difficulty moving; difficulties.

Symptoms of gastroparesis include bloating, nausea, early fullness while eating meals, heartburn, and epigastric pain. These symptoms are often referred to as dyspepsia. Ingestion of solid foods, high fiber foods such as raw fruits and vegetables, fatty foods or drinks high in fat or carbonation may cause symptoms. Perhaps the most common symptom is early satiety, or the sensation of feeling full shortly after starting a meal. Nausea and vomiting are also common. A person with gastroparesis may regurgitate or vomit undigested food many hours after their last meal. Weight loss can occur due to poor absorption of nutrients, or taking in too few calories. Causes. There are many causes of gastroparesis. Diabetes is one of the most common causes for gastroparesis. Ghrelin (pronounced / V Bloc Therapy - All You Need to Know. Reviewed by: Frank Chae, MD, CF, FACS. Other causes include infections, endocrine disorders like hypothyroidism, connective tissue disorders like scleroderma, autoimmune conditions, neuromuscular diseases, idiopathic (unknown) causes, psychological conditions, eating disorders, certain cancers, radiation treatment applied over the chest or abdomen, some chemotherapy agents, and surgery of the upper intestinal tract. Any surgery on the esophagus, stomach or duodenum may result in injury to the vagus nerve which is responsible for many sensory and motor (muscle) responses of the intestine. In health, the vagus nerve sends neurotransmitter impulses to the smooth muscle of the stomach that result in contraction and forward propulsion of gastric contents. If the vagus nerve is injured by trauma or during surgery gastric emptying may be reduced. Symptoms of postoperative gastroparesis may develop immediately, or months to years after a surgery is performed. It is important to realize that medications prescribed for a variety of conditions may have side effects that cause gastric emptying to slow down. The most common drugs that delay stomach emptying are narcotics and certain antidepressants. Table 1 lists more medications that may delay stomach emptying. If possible, patients having dyspeptic symptoms, vomiting or early fullness should discontinue the offending medications before undergoing any motility tests. Fortunately, gastric emptying resumes and symptoms improve when medications causing . It is important to have the names of all your medications recorded and with you when you see a physician for evaluation of gastrointestinal symptoms. People with eating disorders such as anorexia nervosa or bulimia may also develop delayed gastric emptying. Gastric emptying may resume and symptoms improve when food intake and eating schedules normalize. Table 1. Medications associated with impaired gastric emptying. Narcotic Tricyclic antidepressants. Calcium channel blockers. Clonidine. Dopamine agonists. Lithium. Nicotine. Progesterone. Diagnosis. Medications that cause slow emptying should typically be stopped, and reversible conditions (example: hypothyroid) treated prior to testing. A history of early satiety, bloating, nausea, regurgitation or vomiting with meals would normally prompt an evaluation to determine the cause of symptoms. Inflammation, ulcer disease, or obstruction by a tumor can also cause these symptoms and diagnostic tests would be used to determine the cause. Radiographic tests, endoscopic procedures, and motility tests are used to exclude obstruction, to view the stomach lining and obtain biopsies, and to examine muscle contraction patterns. The endoscope has camera capabilities and allows the upper gastrointestinal tract to be evaluated for ulcers, inflammation, infection, cancer, hernias or other abnormalities. These conditions can cause symptoms similar to gastroparesis. Upper endoscopy usually requires 1. Medication is usually administered intravenously immediately before the test for comfort and sedation. If abnormal findings such as an ulcer or inflammation are noted biopsies can be obtained.

Gastric Emptying Study is a widely available nuclear medicine test that examines the rate of emptying of solid or liquid material from the stomach. A delay in gastric emptying indicates a diagnosis of gastroparesis. Subjects consume an egg and toast or oatmeal meal along with milk or orange juice. The food portion contains a tiny amount of the radioactive material (9. Tc), which is measured by a scanning technique as it empties from the stomach. A longer test can examine if small intestine transit is also affected. Scintigraphic Gastric Accommodation is a test that measures the volume of stomach contents before and after a meal, and how well the stomach relaxes in response to food intake. This test uses a tiny amount of radioactive material (9. Tc) which is selectively taken up by the lining of the stomach, and indirectly measures the volume of the stomach. The subject consumes a nutrient drink over 3. A scan of the stomach is taken before and after the nutrient drink. The test indicates whether the stomach relaxes appropriately when filled. Symptoms of poor stomach relaxation can be identical to poor emptying, and this test can help distinguish the processes. Scintigraphic gastric accommodation is not readily available. Gastroduodenal manometry is a test that measures how well the smooth muscle of the stomach and small intestine contracts and relaxes. The test is performed by placing a thin tube into the stomach usually with the aid of the endoscope. The tube is advanced into the small intestine and over the next few hours the contractile responses while the subject is fasting and eating are observed and recorded. The manometry catheter provides information on how strong and how often the muscles of the stomach and intestine contract and whether the stomach contractions are coordinated with the contractions in the small bowel. Gastric duodenal manometry may be helpful but is often not needed to make a diagnosis of gastroparesis. This test is not widely available. A Small Intestinal X- ray is a contrast radiograph used to outline the anatomy of the small bowel. This study is not generally needed to make a diagnosis of gastroparesis, but a blockage anywhere in the small intestine will result in a back up of material and could account for delayed gastric emptying. An obstruction in the small bowel may cause symptoms similar to gastroparesis, but the treatment is different. Treatment for intestinal obstruction is avoiding intake of any food or liquid until the cause of obstruction such as inflammation resolves or surgery is performed to remove the blockage. Wireless capsule GI monitoring system (Smart. Pill. The information from the wireless capsule is transmitted to a receiver worn by the patient around their waist. The information is used to determine how fast or slow the stomach empties, and similarly how food and liquid move through the intestine. The test is done in an outpatient setting, takes generally 3- 6 hours and within 2. A potential advantage of the wireless capsule system over conventional gastric emptying or scintigraphy would be that the study could be done in the outpatient setting and would not involve radiation, though the amount of radiation used in alternative tests is very small and not considered harmful. Occasionally, if the capsule is not passed within three days your doctor may request an abdominal x- ray to assure it has left the body. Use of the wireless capsule monitoring system is not recommended in patients who have had previous surgery to decrease the amount of acid they are secreting, in patients who are unable to stop their antacid medications for the study or in patients with narrowing of the bowel lumen. Treatment. Importance of Nutrition as Treatment in Gastroparesis. Diet is one of the mainstays of treatment for those who suffer from gastroparesis. Some foods are more difficult than others for the stomach to digest. Fatty foods take a longer time to digest, as do foods that are fibrous, like raw vegetables. People with gastroparesis should reduce their intake of fiber or avoid these foods. Fiber when eaten should be chewed well and cooked until soft. Food that is poorly digested can collect in the stomach and form what is called a bezoar. This mass of undigested matter may cause a blockage, preventing the stomach from emptying and result in nausea and pain. In such a case, it may be necessary to use endoscopic tools to break the bezoar apart and remove it. Fortunately, even when stomach emptying is significantly impaired, thick and thin liquids (e. Many people with gastroparesis can live a relatively normal life with the aid of supplemental nutritional drinks, soft foods the consistency of pudding and by pureeing solid food in a blender. Feeding tubes placed in the small intestine (jejunostomy) may be required if gastric paralysis is severe and a person is unable to manage with a pureed or soft diet. These feeding tubes are usually placed endoscopically or surgically through the skin and directly into the small intestine (figure 1). Before such a feeding tube is placed, a temporary nasal or oral jejunal feeding tube is usually tried for a few days to make sure the individual can tolerate this form of feeding into the small bowel. The temporary feeding tube is usually placed by guiding it through the nose or mouth, down the esophagus or “food pipe”, through the stomach and finally into the small intestine with the aid of an endoscope (figure 2).
