Why You Need to Distinguish Between Gastroptosis and Gastric Atony

That bloated feeling, as if something is pressing down, what is it?

Hello. This is Baeknokdam Korean Medicine Clinic.

Have you ever felt like your stomach sags downwards after a meal, feeling heavy, and as if something has settled low?

Or have you experienced constant discomfort, feeling full even after eating a small amount, as if something is still lingering in your stomach?

In such cases, you might hear diagnoses like ‘gastroptosis’ or ‘gastric atony’ from doctors.

You've probably heard both terms frequently. But are they the same? Or are they different?

Today, let's discuss the structural and functional differences between gastroptosis and gastric atony, and how they can be interpreted in the context of symptoms.

Gastroptosis – A Structural Condition Where the Stomach's Position Has Dropped Downwards

Gastroptosis, as the name suggests, is a condition where the stomach sags downwards. Normally, the stomach should be located below the xiphoid process, in the left upper abdomen. Anatomically, gastroptosis is defined as when the lower curvature of the stomach descends below the duodenum.

This phenomenon is commonly observed in individuals with a naturally slender build or weak abdominal wall muscles. Additionally, rapid weight loss, decreased abdominal pressure after childbirth, and lifestyle patterns that involve prolonged standing can also contribute.

It also frequently occurs in individuals who primarily breathe thoracically and struggle with proper diaphragmatic breathing.

However, not all cases of a descended stomach are problematic. If there are no symptoms, it can be considered a simple anatomical variation. But if the lower abdomen consistently feels heavy, or a persistent feeling of indigestion and sagging occurs after meals, then it can be viewed not just as a positional issue, but as a structural factor that impedes proper function.

From an integrated perspective, it is also interpreted that soft tissues such as the peritoneum, serous membrane, and greater omentum, which support the stomach, fail to perform their roles, causing the stomach to be gradually pulled downwards by gravity. In fact, since the tension of the serous membrane, the maintenance of abdominal pressure, and the movement of the diaphragm all influence the stomach's position, an approach that restores the overall supportive strength of the surrounding structures, rather than simply trying to pull the stomach up, is crucial.

Gastric Atony – Functional Impairment Where the Stomach Cannot Properly Propel Food

On the other hand, gastric atony is a condition where the stomach's position is normal, but its motility is weakened. Food enters the stomach, but there isn't enough strength to propel it downwards.

In this state, bloating persists for several hours after a meal, early satiety is severe, and it may be accompanied by excessive burping or vomiting.

It is particularly common in individuals with diabetes, those with autonomic nervous system disorders, or as a sequela following food poisoning.

The problem here lies in the nervous system that coordinates the stomach's peristalsis. The stomach is composed of smooth muscle, so it moves involuntarily. This movement is coordinated by the vagus nerve and the interstitial cells of Cajal (ICC) that generate its rhythm.

However, if this rhythm is disrupted by factors such as diabetes, inflammation, stress, or medications, the stomach cannot contract, and food remains stagnant. Indeed, many studies show a reduced density of interstitial cells of Cajal in patients with gastric atony. While recovery is not impossible, it is limited, and treatment is required to increase the sensitivity of remaining cells or to re-induce the contractile rhythm through electrical stimulation.

Structure vs. Function – How Gastroptosis and Gastric Atony Differ

To summarize: Gastroptosis is a problem of the stomach's position, whereas gastric atony is a problem of the stomach's movement or motility. While they may appear similar outwardly, the underlying mechanisms are entirely different.

Gastroptosis is characterized by a feeling of pressure in the lower abdomen, with symptoms worsening upon standing. Gastric atony, on the other hand, is characterized by a feeling of stuffiness in the upper abdomen after meals and a prolonged sensation that digestion is not progressing.

However, both conditions can exist simultaneously. For instance, if the stomach sags downwards, the gastric outlet can become abnormally bent, creating a structural impediment where gastric contents cannot easily pass. Alternatively, individuals with low abdominal pressure and shallow breathing may experience both gastroptosis and gastric atony concurrently.

Treatment Focuses on Symptom Reduction, Not Simply Raising the Stomach's Position

What's important is that treating gastroptosis does not involve physically pulling the stomach up. If abdominal pressure, abdominal wall muscles, and diaphragm function are restored, symptoms may no longer occur even if the stomach remains descended.

Similarly, for gastric atony, the key is not to strengthen stomach muscles, but to stabilize the autonomic nervous system and restore peristaltic rhythm. Eating small, frequent meals, choosing easily digestible foods, and considering treatments such as prokinetics or electrical stimulation if necessary, are all part of the approach.

Behind the phrase ‘My Stomach Feels Abnormal,’ Two Questions Are Needed

If you're experiencing stomach discomfort, you should ask yourself: 'Is the problem with my stomach's position, or is it with its function?'

And if both the position and function appear normal but you still feel uncomfortable, it could be a sign that the coordination between structure and function is disrupted somewhere. Identifying the true underlying cause is essential for accurate treatment.

Don't just accept diagnoses like 'It's gastroptosis' or 'It's gastric atony.' A holistic perspective is needed, one that examines structural aspects, functional aspects, and even neurological coordination.

Thank you.
