Gastric Motility Disorder in Cats


Overview of Gastric Motility Disorder in Cats

Gastric motility disorders are abnormalities that result from conditions that disrupt normal emptying of the stomach resulting in distention and subsequent abnormal function of the stomach.

Causes of Gastric Motility Disorder in Cats

There are many causes of gastric motility disorders, including:

Metabolic Disorders

  • Hypokalemia (low potassium)
  • Renal (kidney) failure
  • Nervous Inhibition

  • Stress
  • Fear
  • Pain
  • Trauma
  • Primary Stomach Diseases

  • Blockages
  • Gastritis (inflammation of the stomach)
  • Ulcers
  • Previous gastric surgery
  • Miscellaneous

  • Gastroesophageal reflux (backward flow) of gastric/intestinal juice
  • Dysautonomia (dysfunction of a part of the nervous system)
  • Primary idiopathic (Unknown cause)
  • Drugs

    Gastric motility disorders are seen in both dogs and cats. There are no sex, breed or age predilections, however it is uncommon to see primary disorders in younger animals.

  • What to Watch For

  • Chronic vomiting after eating
  • Gastric distention
  • Nausea
  • Anorexia (poor appetite)
  • Belching
  • Pica (eating inappropriate things)
  • Weight loss
  • Diagnosis of Gastric Motility Disorders in Cats

    A thorough knowledge of history and clinical signs is very important and is most helpful in making the diagnosis. Diagnostic tests are necessary to confirm a diagnosis of gastric motility disorders. They include:

  • Complete blood count (CBC)
  • Biochemical profile
  • Urinalysis
  • Fecal flotation
  • Abdominal radiographs (x-rays)
  • Abdominal ultrasound
  • A contrast (dye) upper gastrointestinal study
  • Endoscopy, specifically gastroscopy
  • Treatment of Gastric Motility Disorders in Cats

    Treatment for gastric motility disorders is dependent upon the precise disease. In addition, symptomatic/supportive therapy may be indicated, regardless of the disease itself.

  • Most patients are treated as an outpatient
  • Hospitalization/supportive care in extreme/severe cases of disease
  • Dietary modification
  • Stomach acid blockers
  • Gastric coating agents
  • Prokinetic (promote movement) agents
  • Surgical intervention for certain disorders (blockages)
  • Home Care and Prevention

    Administer prescribed medication and follow all feeding instructions. Contact your veterinarian if signs continue or worsen.

    There is no specific preventative care available.

    In-depth Information on Feline Gastric Motility Disorders

    Gastric motility disorders result from conditions that directly or indirectly disrupt normal emptying of the stomach that results in gastric distention and subsequent signs of illness. Although some gastric motility disorders are primary, the majority of cases occur secondary to other conditions or disorders.

    The magnitude of clinical signs depends on both the specific disease process and the severity of that disease. The clinical signs are often chronic, often present for weeks or months and most often include some degree of vomiting, usually of food. Because the history, physical exam findings and overall presentation of animals with gastric motility disorders may be variable and sometimes nonspecific, there are other illnesses and symptoms that might initially be considered when establishing a definitive diagnosis, especially those that cause chronic vomiting. These include:

  • Chronic, recurrent dietary indiscretion, especially overeating and ingesting foreign material.
  • Dietary intolerance can cause chronic vomiting, and mimic gastric motility disorders. They are often associated with protein, lactose, diets high in fat and certain food additives.
  • There are many infectious agents that can cause chronic vomiting. Bacterial, viral, fungal and parasitic diseases are common. Parvovirus is one of the more likely offenders.
  • Chronic drug administration and/or toxin exposure can cause chronic vomiting by directly irritating the lining of the gastrointestinal tract. Examples include non-steroidal anti-inflammatory drugs (aspirin), corticosteroids, antibiotics, insecticides, heavy metals, and lawn and garden products.
  • Obstruction/blockage of the gastrointestinal tract causes an outflow obstruction, and in turn, motility disorder. This is usually secondary to the presence of chronic foreign bodies, tumors, intussusceptions (telescoping of the bowel into itself), hypertrophic gastropathy (thickening and malfunction of the pyloric area of the stomach) or parasites.
  • Patients with metabolic diseases such as kidney, liver, diabetes mellitus and hypoadrenocorticism (Addison’s disease), may present for signs similar to those with motility disorders.
  • Any patients with abdominal disorders present for vomiting. Chronic pancreatitis (inflammation of the pancreas), prostatic disorders, and low-grade peritonitis (inflammation of the abdominal cavity) should be considered.
  • Neurologic disorders, especially vestibular disease, can stimulate the area in the brain involving the vomiting reflex. Dysfunction of the autonomic nervous system (dysautonomia) has been recognized as a cause as well.
  • Inflammatory bowel disease is a microscopic accumulation of inflammatory cells of any/all parts of the gastrointestinal tract. No one cause has been identified. Vomiting is one of many signs that may be seen.
  • Lymphangiectasia is an intestinal disorder characterized by the dilation of lymph vessels throughout the gastrointestinal tract, causing chronic vomiting, diarrhea, protein loss and weight loss.
  • Gastrointestinal ulcers are associated with liver disease, kidney disease, stress, or pancreatic disease. Chronic vomiting, with or without blood is commonly seen.
  • A hiatal hernia is the sliding of abdominal contents into the chest cavity through the diaphragm.
  • Lymphosarcoma (a type of cancer) is most often a microscopic disease that infiltrates the gastrointestinal tract, and can cause many GI signs. It is seen in all ages and breeds.
