There are many different diseases that affect your stomach. I found a list with a little bit of information of each of them for you!
Here they are:


In the stomach there is a slight balance between acid and the wall lining which is protected by mucus. When this mucus lining is disrupted for whatever reason, signs and symptoms of acidity result. This may result in upper abdominal pain, indigestion, loss of appetite, nausea, vomiting and heartburn. When the condition is allowed to progress, the pain may become continuous; blood may start to leak and be seen in the stools. If the bleeding is rapid and of adequate volume it may even result in vomiting of bright red blood (hematemesis). When the acidity is uncontrolled, it can even cause severe blood loss (anemia) or lead to perforation (hole) in the stomach which is a surgical emergency. In many individuals, the progressive bleeding from an ulcer mixes with the feces and presents as black stools. Presence of blood in stools is often the first sign that there is a problem in the stomach.[4]


Another very common long term problem which is now more appreciated is gastroparesis. Gastroparesis affects millions of individuals and is often never suspected and most patients have a delay in diagnosis. Basically in gastroparesis, the stomach motility disappears and food remains stagnant in the stomach. The most common cause of gastroparesis is diabetes but it can also occur from a blockage at the distal end of stomach, a cancer or a stroke. Symptoms of gastroparesis includes abdominal pain, fullness, bloating, nausea, vomiting after eating food, loss of appetite and feeling of fullness after eating small amounts of food.


During digestion, food is stored in the liquid present in the stomach. The food that is not digested travels to the small intestine and colon in liquid form. These organs begin to absorb the water turning the food into a more solid form. Different viruses or bacteria can increase the amount of liquid that is secreted and moves too quickly through the digestive tract for the water to be absorbed. Diarrhea can exist in one of two types, acute diarrhea or chronic diarrhea. The acute diagnosis can last for a few days up to a week of time. Chronic diarrhea lasts for several days or longer periods of time lasting a few weeks. The difference in diagnosis will help determine the cause of the illness.

Crohn's disease

Crohn's disease is an inflammatory bowel disease that can affect any part of the digestive tract, even the stomach, although it's a rare presentation. Its main feature is inflammatory ulcers that can affect the total thickness of the stomach wall and can bleed but rarely perforate. Symptoms include abdominal pain, loss of appetite, and weight loss. Diarrhea is also a symptom that can develop, so checking stools for the appearance of blood is important. It is possible for symptoms of Crohn's Disease to remain with a person for weeks or go away on their own. Reporting the symptoms to a doctor is recommended to prevent further complications.


Cancers of the stomach are rare and the incidence has been declining worldwide. Stomach cancers usually occur due to fluctuations in acidity level and may present with vague symptoms of abdominal fullness, weight loss and pain. The actual cause of stomach cancer is not known but has been linked to infection with H.pylori, pernicious anemia, Menetriere's disease, and nitrogenous preservatives in food.
