Gastroparesis is a condition that affects the normal movement of the muscles in the stomach, resulting in delayed gastric emptying. The pathophysiology of gastroparesis is complex and can involve several mechanisms, including impaired gastric motility, dysfunction of the enteric nervous system, and abnormalities in smooth muscle function. In a healthy individual, the stomach's muscles contract in a coordinated manner to propel food into the small intestine [1]. However, in gastroparesis, these contractions are either weak or uncoordinated, leading to food remaining in the stomach for longer than usual, causing symptoms like nausea, vomiting, bloating, and early satiety. The primary defect in gastroparesis is often related to the vagus nerve, which plays a central role in controlling the stomach's motility [2]. The vagus nerve carries signals from the brain to the stomach, regulating the contraction and relaxation of the stomach muscles. In gastroparesis, these signals may be disrupted, leading to a slowing of gastric emptying. This disruption can be caused by a variety of factors, including diabetes, which is one of the most common causes of gastroparesis. In diabetic patients, hyperglycemia can damage the vagus nerve, impairing its function and leading to delayed gastric emptying. Additionally, the smooth muscle cells in the stomach may become less responsive to the electrical impulses that stimulate contractions, further worsen the condition [3].
Another important aspect of gastroparesis is the dysfunction of the enteric nervous system, which is sometimes referred to as the "second brain" due to its vast network of neurons in the gastrointestinal tract. The enteric nervous system coordinates the movements of the digestive system, and when it is not functioning properly, it can lead to impaired motility in the stomach [4]. In some cases, the muscles themselves may be affected, causing them to become less contractile and contributing to delayed gastric emptying. In addition to the neural and muscular dysfunctions, inflammation and oxidative stress may also play a role in the pathophysiology of gastroparesis. Inflammatory cytokines and other molecules involved in the body's immune response can alter the function of the enteric nervous system and the smooth muscle cells, contributing to the overall dysfunction. This inflammation is often seen in patients with underlying conditions like diabetes or other chronic diseases, where the body's inflammatory response is increased [5].
The management of gastroparesis is multifaceted and often requires a combination of lifestyle changes, pharmacological treatments, and, in some cases, surgical interventions. The primary goal of treatment is to alleviate symptoms and improve gastric emptying, thereby improving the patient's quality of life. Dietary modifications are one of the first steps in managing gastroparesis. Because food may remain in the stomach for longer periods, smaller, more frequent meals are recommended. A lowfat, low-fiber diet is often advised since these types of foods are easier to digest and are less likely to exacerbate symptoms [6]. Fatty foods, in particular, can slow gastric emptying, making the symptoms worse. Liquid meals or pureed foods may also be suggested to help reduce the workload on the stomach, as they are easier to digest and pass through the stomach more quickly. Pharmacological treatments play a significant role in the management of gastroparesis, with a focus on improving gastric motility and reducing symptoms such as nausea and vomiting [7]. Prokinetic agents are commonly used to stimulate the stomach's muscles and improve gastric emptying. These medications work by increasing the contractility of the stomach muscles, helping to propel food into the small intestine. However, these drugs can have side effects, including gastrointestinal discomfort and central nervous system effects, so their use must be carefully monitored [8].
Antiemetic drugs are also frequently used to control nausea and vomiting, which are common symptoms of gastroparesis. These medications work by blocking the signals that trigger nausea, helping to provide relief [9]. In some cases, medications that act on the serotonin receptors in the gastrointestinal tract may be used, as serotonin plays a role in regulating motility and nausea. These medications can help alleviate the nausea associated with gastroparesis, improving the patient's ability to tolerate food and fluids. For patients who do not respond to dietary modifications and pharmacological treatments, more invasive interventions may be necessary. One such approach is the use of gastric electrical stimulation, which involves implanting a device that delivers electrical impulses to the stomach muscles [10]. This device can help improve gastric motility and reduce symptoms, although its effectiveness can vary from patient to patient. The implantation of a gastric pacemaker may be considered for those with severe, refractory symptoms who have not responded to other treatments.
