Shared signs and symptoms of stomach diseases
Firstly, pain is a non-specific symptom of many diseases and conditions. Furthermore, pain is subjective as each person has their own level of tolerance. Generally, stomach pain is felt in the upper-left portion of the abdomen.
However, the pain can radiate upward toward the area of the heart, commonly called “heartburn”. The stomach itself does not have pain receptors, however, the nerves around it are sensitive to stretch and pain.
Distention (stretching), after eating too much or when gas builds up in the stomach, causes discomfort but not severe pain. Indigestion is another term for this feeling. On the other hand, ulceration and perforation of the stomach can feel like a dull or gnawing pain. This often occurs in PUD.
Pain alone is not one of the most useful signs of stomach cancer because it can easily mimic these diseases. However, more advanced stages of stomach cancer may present with more severe pain.
Next, for people with gastroesophageal reflux disease (GERD), acid from the stomach travels up the esophagus and damages the tissue along the way.
If GERD is not managed well, they can experience trouble swallowing or dysphagia. Dysphagia also occurs in people who have stomach cancer, depending on the size and location of the tumor growth.
Loss of appetite
Lastly, the inability to eat or loss of appetite is another one of the shared signs of stomach cancer and other diseases. This is common when someone has the stomach flu or gastroenteritis. Aside from gastrointestinal diseases, infections caused by the flu or other pathogen typically cause loss of appetite.
