Majority of people may suffer from haemorrhoids at some point in their life time. It is more common in individuals aged between 45 and 65 years and in pregnant women.

The appendix is a finger-shaped tube 3½-inches long extending from the right side of the large intestine. The exact function of this organ is not very clear. Appendicitis is a condition in which the appendix becomes inflamed and filled with pus. It is a medical emergency requiring immediate surgical removal of the appendix.
Cholecystitis is inflammation of the gallbladder. The gallbladder is a pear-shaped organ which lies just below the liver. The gallbladder stores bile, a digestive fluid that is sent from the liver. Most cases of cholecystitis are caused by gallstones. Gallstones are crystalline structures that develop in the gallbladder or the bile ducts and can interfere with the normal flow of bile leading to inflammation.
Oesophagitis may be caused by different conditions and sometimes more than one factor may play a role. Reflux oesophagitis occurs when acidic contents of the stomach enter the oesophagus causing irritation. A sphincter muscle at the junction of the oesophagus and stomach usually prevents this from happening, but it may occur with gastroesophageal reflux disease, vomiting, hiatal hernia, achalasia or following bariatric surgery.
Peritoneum is a lining of tissue that covers most of the internal organs as well as the inner side of the abdominal wall.

Other symptoms include fever, vomiting, nausea, sweating, swelling in the abdominal region, feeling of fullness due to gas, mild jaundice and clay-coloured stools.
