Why Do I Always Feel a Fullness in My Stomach?

When there is frequent feeling of gastric distension, it is advisable to avoid foods that easily cause gas production. This is often due to a slowdown in intestinal motility, leading to indigestion and symptoms such as bloating. Many patients also experience this due to eating too quickly. Therefore, it is important to change habits of overeating and binge eating. Eating smaller meals more frequently and chewing food thoroughly can help improve intestinal motility and prevent damage to the gastric mucosa.

1.1 Swallowing excessive air into the stomach, which can lead to bloating due to rapid eating, excessive saliva secretion, and swallowing large amounts of air.

1.2 Excessive gas production in the gastrointestinal tract, such as indigestion and short bowel syndrome, can lead to the production of large amounts of gas by bacteria in the colon, resulting in bloating.

1.3 Impaired lung function in exhaling CO2, such as respiratory failure, can lead to CO2 accumulating in the intestine and causing bloating.

1.4 Obstacles in anal gas expulsion, such as intestinal obstruction, paralysis, congenital megacolon, and diabetic gastroparesis, can lead to gas accumulation and bloating.

Abdominal fluid accumulation, such as peritonitis and ascites (including abdominal hemorrhage), can result from decreased plasma osmotic pressure, venous circulation disorders, increased portal venous pressure, blocked lymphatic fluid return, increased capillary permeability, rupture of abdominal organs, or ectopic pregnancy, leading to a large amount of fluid accumulating in the abdominal cavity, compressing the gastrointestinal tract, stretching the peritoneal membrane and supporting tissues, and causing bloating.

Gastrointestinal perforation can allow gas from the stomach or intestines to enter the abdominal cavity, causing bloating.

Large abdominal masses or masses that compress the gastrointestinal tract can cause gastrointestinal obstruction and result in bloating. Examples include ovarian cysts, renal cysts, pancreatic pseudocysts, liver cancer, renal pelvis hydronephrosis, mesenteric cysts, megalosplenia, and urinary retention.

Conditions such as indigestion, short bowel syndrome, respiratory failure, intestinal obstruction, intestinal paralysis, congenital megacolon, diabetic gastroparesis, peritonitis, ascites, rupture of abdominal organs or ectopic pregnancy, gastrointestinal perforation, ovarian cysts, renal cysts, pancreatic pseudocysts, liver cancer, renal pelvis hydronephrosis, mesenteric cysts, megalosplenia, and urinary retention can all lead to abdominal wall fat accumulation and potentially contribute to bloating.
