Nausea and/or Vomiting
Nausea and vomiting are likewise common symptoms, with many causes which are more common than stomach cancer. If you have nausea and vomiting which persists, however, there is a greater chance that it is signaling a more serious issue. If your symptoms are lasting, or if you vomit up any blood (even if just a small amount), make an appointment to see your doctor right away. If you are vomiting up a large amount of blood (more than a few teaspoons) don’t wait to make an appointment and call 911. Gastric hemorrhage is a medical emergency.
It’s important to remember that the occurrence of nausea and vomiting alone, without other stomach cancer symptoms, is unlikely an indication of cancer. There are lots of reasons for feeling sick and throwing up. That being said, if nausea and vomiting are accompanied by other worrisome signs such as constipation, abdominal cramping, and/or abdominal distension, stomach cancer could be a cause.
