This article explains what electrogastrography (EGG) is, how it works, and why it is used to diagnose digestive disorders.
Electrogastrography: Understanding the Basics
Electrogastrography (EGG) is a non-invasive diagnostic test used to measure the electrical activity of the stomach. The test involves placing electrodes on the surface of the skin, which record the electrical signals produced by the muscles in the stomach.
How Does EGG Work?
The stomach is a muscular organ that contracts and relaxes to help break down food and move it through the digestive system. These contractions create electrical signals that can be measured by an EGG machine.
During an EGG test, the patient is asked to fast for a certain period before the test. Then, small electrodes are placed on the surface of the skin on the abdomen. These electrodes detect the electrical signals generated by the muscles of the stomach.
The patient may be asked to eat a meal or consume a liquid during the test. As the food or liquid enters the stomach, the muscles contract to mix it with digestive juices. This creates a series of electrical signals that are recorded by the EGG machine.
The EGG machine records the electrical activity of the stomach and produces a graph that shows the patterns of electrical activity. These patterns can provide valuable information about the function of the stomach and help diagnose conditions that affect the digestive system.
Why Is EGG Used?
EGG is used to diagnose a variety of digestive disorders, including gastroparesis, functional dyspepsia, and irritable bowel syndrome (IBS). Gastroparesis is a condition in which the muscles of the stomach do not work properly, causing food to move slowly through the digestive system. Functional dyspepsia is a condition in which the stomach muscles contract abnormally, causing pain, bloating, and other symptoms. IBS is a condition in which the digestive system is hypersensitive, leading to abdominal pain, bloating, and changes in bowel habits.
EGG can also be used to evaluate the effects of medications on the digestive system. For example, EGG can be used to determine whether a medication is speeding up or slowing down the contractions of the stomach muscles.
In conclusion, EGG is a valuable diagnostic tool for evaluating the function of the stomach and diagnosing digestive disorders. The test is non-invasive, safe, and painless, making it an attractive option for patients who may be hesitant to undergo more invasive procedures.
Preparing for an EGG Test
If you are scheduled for an EGG test, your doctor will provide instructions on how to prepare for the test. Typically, you will be asked to avoid eating or drinking for a certain period of time before the test. You may also be asked to stop taking certain medications or supplements prior to the test.
During the test, it is important to remain still and avoid any movements that could interfere with the electrodes. You may be asked to lie down or sit still while the electrodes are attached to your skin. The test usually takes about an hour to complete.
Interpreting EGG Results
Once the EGG test is complete, the results are analyzed by a trained healthcare provider. The EGG graph shows the patterns of electrical activity in the stomach over time. These patterns can help diagnose conditions that affect the stomach’s function.
If the EGG results show abnormal patterns of electrical activity, further testing may be needed to diagnose the underlying condition. Depending on the results, your healthcare provider may recommend additional tests, medications, or lifestyle changes to improve your digestive health.
Conclusion
Electrogastrography is a valuable diagnostic tool for evaluating the function of the stomach and diagnosing digestive disorders. The test is safe, non-invasive, and painless, making it an attractive option for patients who may be hesitant to undergo more invasive procedures. If you are experiencing symptoms related to your digestive health, talk to your healthcare provider about whether an EGG test is right for you. With accurate diagnosis and appropriate treatment, you can improve your digestive health and quality of life.
