This is because the stomach is an essential organ when it comes to digesting food. Therefore, any cancer here can severely affect your nutrition and weight.
As mentioned previously, vomiting is a common sign of many GI diseases. Vomiting can even occur due to anxiety or nervousness. Generally, the contents of the vomitus are stomach acid, water, and food particles.
Severe cases of PUD and GERD may have reddish streaks or “coffee ground” vomit. However, large amounts of red or brownish vomit may be a stronger indication of stomach cancer.
Weakness and fatigue
Last, but not least, severe weakness and fatigue are two signs of stomach cancer. Weakness and fatigue are common with other types of cancers and chronic diseases.
However, when coupled with the other warning signs, it can point more toward stomach cancer. Because food intake and nutrition are more affected in stomach cancer, weakness and fatigue may be felt earlier on or be more severe. Anemia may also be a cause of weakness and fatigue.
In summary, the signs of stomach cancer can be misleading at times. Due to the lower incidence of this type of cancer, other causes of stomach pain and nausea have to be considered first.
For people who currently have GERD, PUD, or gastroenteritis, there is no need to worry about stomach cancer unless you are experiencing unexplained weight loss or excessive bleeding.
