4 signs appearing in the morning warning of stomach cancer

The initial symptoms of stomach cancer are often vague and easily misunderstood due to the effects of stress and mild digestive disorders. In many cases, patients discover some unusual symptoms in the morning, before eating anything.

Signs that appear in the morning can be a warning sign of stomach cancer, including:

Stomachache

Dull or cramping pain upon waking up, even before breakfast, can be an early warning of stomach cancer. As the tumor grows, gastric acid comes into direct contact with the tumor throughout the night, creating a burning sensation, fullness, or dull pain in the epigastric region, according to the health website Healthline (USA).

Morning abdominal pain is one of the common signs of stomach cancer.

Many patients describe the pain as waking them up in the morning. In addition, after eating a light meal, the pain will temporarily decrease. If the symptoms recur daily, increase in severity, or spread to the back, the patient should see a doctor for an endoscopy. Statistics show that stomach pain occurs in both the early and advanced stages of stomach cancer, often accompanied by a feeling of fullness even after eating a small amount.

Persistent nausea is an early symptom of stomach cancer.

Persistent nausea in the morning, even after eating nothing, is a sign that the stomach lining is irritated or partially blocked. This condition causes food and gastric juices to stagnate.

The National Cancer Institute (NCI) lists nausea as an early symptom of stomach cancer. However, this symptom is often overlooked because it is mistaken for acid reflux. People should see a doctor if nausea persists, or if they experience a fishy or bitter taste in their mouth, especially if the vomit contains blood.

Chronic indigestion

Persistent indigestion is another warning sign of stomach cancer. This condition is accompanied by a burning sensation in the epigastric region, belching, heartburn or a feeling of bloating even after just drinking a few sips of water in the morning. The cause is due to the tumor blocking the flow of food, disrupting acid secretion.

If this symptom is accompanied by bad breath, bloating, and fatigue, it could be a sign of deep mucosal damage or microscopic bleeding.

Black stool

Black, sticky, foul-smelling stools in the morning are a sign of blood being broken down by digestive juices. This is a sign of upper gastrointestinal bleeding, often caused by a tumor invading the blood vessels of the stomach.

The Cleveland Clinic, a non-profit medical center in the US, said that the viscosity and black color in the stool is due to hemoglobin, a protein in red blood cells, being oxidized when passing through the intestines. Therefore, if you see signs of black and sticky stool, you need to be hospitalized immediately even if you do not feel pain, according to Healthline .
