Indigestion Right After Eating: Could It Be Gastric Atony?

Gastric atony can be a more complex and serious condition than it appears. Modern medicine also refers to it as gastroparesis or delayed gastric emptying, describing a state where peristalsis responsible for moving food into the small intestine is diminished, causing food to remain abnormally long inside the stomach. The causes of gastric atony are diverse. One of the most common causes is diabetes. Hyperglycemia can damage nerves and impair the function of the vagus nerve, which regulates gastric motility. It is much like the conductor of our digestive system coming to a halt. In addition, underlying conditions such as hypothyroidism, Parkinson's disease, and autoimmune diseases can lead to gastric atony. Postoperative complications that damage the vagus nerve, or side effects from specific medications such as opioid analgesics and certain antidepressants, can also inhibit gastric motility. Looking closer at the mechanisms that regulate gastric motility, our stomach contains specialized cells called interstitial cells of Cajal. These cells act as pacemakers regulating the contraction and relaxation of gastric smooth muscle. When interstitial cells of Cajal are damaged or functionally impaired, problems arise in gastric peristalsis, resulting in gastric stasis. Furthermore, our brain and gut are connected through an intimate neurological network known as the gut-brain axis. Numerous studies show that psychological factors such as stress, anxiety, and depression can affect this axis, inhibiting or reducing gastric motility. If this continues, the prolonged stagnation of food in the stomach increases the risk of bacterial overgrowth, creating a vicious cycle that worsens dyspeptic symptoms. Simply taking a digestant often fails to provide a fundamental resolution, making an accurate diagnosis and appropriate lifestyle modifications essential. Let us explore what we can do in our daily routine.
