9. Stomach Ulcer
A stomach or gastric ulcer is a break in the tissue lining of the stomach.
Most stomach ulcers are caused by infection with the Helicobacter pylori bacterium or anti-inflammatory medication, not stress or poor diet as once thought.
Treatment options include antibiotics and acid-suppressing medications.

10. Duodenal Ulcer

11. Gastritis
Gastritis can be caused by irritation due to excessive alcohol use, chronic vomiting, stress, or the use of certain medications such as aspirin or other anti-inflammatory drugs. It may also be caused by any of the following:
Helicobacter pylori (H. pylori): A bacteria that lives in the mucous lining of the stomach; without treatment, the infection can lead to ulcers, and in some people, stomach cancer.
Bile reflux: A backflow of bile into the stomach from the bile tract (that connects to the liver and gallbladder)
Infections caused by bacteria and viruses

12. Esophageal Reflux
Gastroesophageal reflux disease (GERD), also known as acid reflux, is a long term condition where stomach contents come back up into the esophagus resulting in either symptoms or complications. Symptoms include the taste of acid in the back of the mouth, heartburn, bad breath, chest pain, vomiting, breathing problems, and wearing away of the teeth. 

13. Colon Cancer

14. Rectal Cancer

15. Enteritis
Inflammation of the intestine, especially the small intestine, usually accompanied by diarrhoea.

16. Glossitis
Inflammation of the tongue.

17. Peritonitis
Peritonitis is inflammation of the membranes of the abdominal wall and organs. Peritonitis is a life-threatening emergency that needs prompt medical treatment.  The abdominal organs, such as the stomach and liver, are wrapped in a thin, tough membrane called the visceral peritoneum. The abdominal walls are similarly lined (parietal peritoneum). A protective layer of fat contained in a membrane (the omentum) sits between the organs and the abdominal wall. Lubricating fluid allows all these membranes to slide smoothly over each other.  The main function of the peritoneum is to permit free movement of the internal organs during digestion. Peritonitis is inflammation of the peritoneum caused by bacterial infection.

18. Hepatitis
Hepatitis is inflammation of the liver tissueHepatitis may be temporary (acute) or long term (chronic) depending on whether it lasts for less than or more than six months.
There are five main types of viral hepatitis: type A, B, C, D, and E. Hepatitis A and E are mainly spread by contaminated food and water. Hepatitis B is mainly sexually transmitted, but may also be passed from mother to baby during pregnancy or childbirth. Both hepatitis B and hepatitis C are commonly spread through infected blood such as may occur during needle sharing by intravenous drug users. Hepatitis D can only infect people already infected with hepatitis B.

19. Hernia
A hernia is the exit of an organ, such as the bowel, through the wall of the cavity in which it normally resides. Hernias come in a number of different types.

20. Stomatitis Types of stomatitis include:
Canker sore: A canker sore, also known as an aphthous ulcer, is a single pale or yellow ulcer with a red outer ring or a cluster of such ulcers in the mouth, usually on the cheeks, tongue, or inside the lip.
Cold sores : Also called fever blisters, cold sores are fluid-filled sores that occur on or around the lips. They rarely form on the gums or the roof of the mouth. Cold sores later crust over with a scab and are usually associated with tingling, tenderness, or burning before the actual sores appear.

21. Pancreas
It is an endocrine gland producing several important hormones, including insulin, glucagon, somatostatin, and pancreatic polypeptide which circulate in the blood. The pancreas is also a digestive organ, secreting pancreatic juice containing digestive enzymes that assist digestion and absorption of nutrients in the small intestine. These enzymes help to further break down the carbohydrates, proteins, and lipids in the chyme.
