Stomach cancer symptoms include eating difficulties, indigestion, heartburn, nausea, vomiting, blood in stool, abdominal pain, fatigue, and weight loss. These symptoms are nonspecific and require a doctor’s examination to determine if they are caused by stomach cancer.
Although most patients experience very few or no symptoms at first, there are several common signs of stomach cancer that occur as the disease progresses. Many people experience eating difficulties, including loss of appetite, difficulty swallowing, and feelings of excessive fullness and bloating after a small meal. Some patients experience indigestion and heartburn, while others may experience gastrointestinal problems such as nausea, vomiting and blood in the stool. Other symptoms may include abdominal pain, fatigue and weight loss. Because these symptoms are fairly nonspecific and can indicate a variety of other problems, and because stomach cancer can get very large before causing significant symptoms, people who have them should typically be examined by a doctor to determine if the culprit is of stomach cancer.
Problems with eating are some of the most common signs of stomach cancer. Some patients tend not to feel hungry as the tumor in the stomach gets bigger and takes up more space. When they eat, they may have difficulty swallowing and ingesting food. Often, eating even a small enough meal can lead to patients feeling overly full and can also cause abdominal discomfort or pain.
Other problems that are often signs of stomach cancer are indigestion and heartburn. Particularly after a meal, patients may tend to feel bloated, gassy, and uncomfortable. They may also notice a burning sensation in their stomach and chest due to acid reflux.
Stomach cancer can also lead to some unpleasant symptoms that affect digestion. As the cancer grows, many people tend to feel nauseous frequently, which often leads to vomiting. In some cases, they may have bleeding in their stomach and blood may be present in their vomit. Blood can also appear in a patient’s stool, making it appear black and tarry.
There are several other signs of stomach cancer that patients may notice during the later stages of the disease. Patients may tend to have a general feeling of discomfort or even pain in the abdomen due to the pressure from the tumor, particularly in the upper and middle sections. They may tend to feel weak or tire easily, sometimes due to a mild case of anemia. Some patients may notice that they are losing weight, partly due to the cancer itself, but possibly also due to problems with getting enough to eat.
