Stomach Cancer Symptoms That Often Go Unnoticed
Gastro Insights Stomach cancer, or gastric cancer, often develops quietly. In its early stages, symptoms are usually mild, vague, or easily mistaken for common digestive issues. This is why many people receive a diagnosis only after the disease has progressed. Recognising these subtle warning signs can make a significant difference, as catching the disease early improves treatment outcomes.
Persistent Indigestion and Discomfort
One frequently overlooked symptom of stomach cancer is ongoing indigestion. Occasional indigestion is normal, but when discomfort, burning, or a feeling of fullness lasts despite changes in diet or medication, it should be taken seriously. Many individuals dismiss these symptoms as acid reflux or gastritis, delaying necessary evaluations.
Feeling uncomfortably full after eating small amounts of food, known as early satiety, is another subtle yet important sign. This might happen when a tumour disrupts the stomach’s capacity to expand normally.
Unexplained Weight Loss and Loss of Appetite
Unintentional weight loss raises a red flag in many cancers, including stomach cancer. If you notice a steady decline in weight without any changes in diet or activity, it deserves medical attention. This often occurs alongside a loss of appetite, especially a sudden dislike for meat or foods you once enjoyed.
These symptoms may develop gradually, making them easy to miss until they become more pronounced.
Nausea, Vomiting, and Fatigue
Chronic nausea or occasional vomiting without a clear cause can be another early sign. In some cases, vomit may contain blood, although this typically happens at more advanced stages. Persistent fatigue and weakness may also arise from internal bleeding or reduced nutrient absorption, leading to anaemia.
Since fatigue is common in busy lifestyles, many fail to link it to an underlying digestive issue.
Abdominal Pain and Bloating
Mild abdominal pain, pressure, or bloating, particularly in the upper abdomen, may be mistaken for gas or food intolerance. Unlike typical bloating, this discomfort often doesn’t fully resolve and may worsen over time. Some people also feel a sensation of tightness or heaviness after eating.
When to See a Gastroenterologist
If you experience persistent digestive symptoms lasting more than a few weeks, it’s important to seek specialist care. Early evaluation by a gastroenterologist can help determine whether symptoms arise from benign conditions or something more serious, like stomach cancer.
You might consider visiting experienced gastroenterologists such as Dr Fernandes Mark Lee, who specialises in digestive and liver diseases and practices at Farrer Park Hospital. You can also receive specialised care from Gutcare Digestive, Liver & Endoscopy Specialists to get comprehensive endoscopy and digestive care services.
These specialists can recommend necessary investigations such as gastroscopy, imaging, or lab tests to ensure a precise diagnosis.
Conclusion
Stomach cancer diagnosed early is often more treatable and may require less aggressive therapy. Unfortunately, since early symptoms are subtle, many people hesitate to seek help. Being aware of these often-unnoticed signs and acting quickly can save lives.
If your digestive symptoms feel unusual, persistent, or progressively worse, do not ignore them. Consulting a qualified gastroenterologist early can provide clarity, reassurance, and timely treatment when it matters most.
