In general, the size of the gastric bubble represents the amount of gas in the stomach.
Under normal circumstances, the gastric bubble is the normal structure of the stomach on X-ray. Usually there is gas present in the stomach, and during fluoroscopy, since the gas does not absorb X-rays, the area of gas appears as a translucent area, which is called a gastric bubble.
Often, if the amount of gas in the stomach increases due to a condition such as indigestion, gastritis, etc., the gastric bubble will usually become larger. Patients who have eaten too much or have fluid in the abdomen usually have smaller bubbles and less gas in the stomach.
If the size of the gastric bubble is abnormal, it is recommended to consult a doctor to determine the cause of the problem and to have it treated with the help of a doctor.
