Stomach Cancer vs Indigestion: Basic differences and when to urgently seek help

The fifth most common cancer around the globe, stomach cancer , is often misunderstood to be indigestion . The late diagnosis is becoming a major cause behind claiming thousands of lives every year. The severity of stomach cancer lies in its subtle onset. Early diagnosis is crucial, as studies show that detecting stomach cancer in its initial stages significantly improves survival rates and treatment outcomes. Differentiating between ordinary indigestion and symptoms of stomach cancer can make a life saving difference.

Indigestion vs stomach cancer: How to identify the difference
Indigestion is often a common digestive issue, also known as dyspepsia. It is experienced by millions around the world. Indigestion usually causes discomfort, bloating, or occasional nausea after meals. This condition usually resolves with lifestyle changes or some over the counter remedies. Stomach cancer, in contrast, develops due to more serious underlying causes. Chronic infection with Helicobacter pylori is a major risk factor. Some studies suggest smoking, excessive alcohol consumption, a diet high in salty, smoked, or processed foods or genetic predisposition can also be the contributing factors. These factors, unlike indigestion, can trigger persistent changes in the stomach lining, potentially progressing to malignancy over years.
Frequent vomiting with blood or struggling to swallow food are the symptoms that show up when the cancer becomes serious. However, very early signs of stomach cancer can mimic common indigestion symptoms. A study from MD Anderson Cancer Center indicates that since the very early symptoms of stomach cancer closely resemble indigestion, it becomes even difficult to detect it. Here are some symptoms that should raise the alarm:

Feeling full even with small meals

Mild bloating or feeling full occasionally after overeating is a typical cause of indigestion, but it should be concerning if one feels a sense of fullness after eating only a small amount of food. Many reports suggest Early satiety is a common symptom of stomach cancer.

Constant heartburn- indigestion

Indigestion from heavy spicy meals can cause indigestion problems and lead to persistent heartburn. But, frequent heartburn or acid reflux that doesn't respond well to antacids may indicate early gastric irritation or changes in the esophagus, which can be early signs of stomach cancer.


Bowel movement difference

Indigestion comes with changes in bowel movements, such as mild constipation or diarrhea. In contrast, studies suggest persistent diarrhea, constipation, or changes in stool consistency can be early signs of gastrointestinal issues, including stomach cancer.

While both stomach cancer and indigestion can present with similar symptoms, the persistence, severity, and lack of response to typical treatments in stomach cancer symptoms make them more concerning. It is essential to seek medical help if one experiences such signs, as doctors may recommend tests for detection. Awareness of differences between a benign condition and a life threatening disease is the first step towards life saving interventions.
