Rectal bleeding (for which the medical term is haematochezia) is a common symptom experienced in the general population. Rectal bleeding refers to the passage of blood from the back passage which may originate from the anus, rectum or higher up in the gastrointestinal tract. There are numerous possible causes for the passage of blood with your stool including anal fissures (tears within the anal wall), haemorrhoids, diverticulosis, colon cancer and polyps, angiodysplasias (abnormal clumps of vessels within the intestine wall) and colitis. In most cases the cause will be harmless and temporary but is important to be investigated by a doctor to exclude something serious such as cancer of your bowel. If you are older than 60 with rectal bleeding it is extremely pertinent that your see your doctor so they can perform the appropriate investigations such as colonoscopy. Further treatment then aims to stop the bleeding and treat the underlying cause.

What Is Pancreatitis?
There are two types of pancreatitis, chronic and acute. Both are inflammations of the pancreas, a gland that produces digestive enzymes, which your body uses to metabolize carbohydrates and fats, and the hormone insulin.
The symptoms of acute pancreatitis are typically severe and need to be treated. If they aren’t, you may develop pancreatic cysts, abscesses, and leaks of pancreatic fluid into the abdomen, which can lead to other long-term problems or even death. Shock is a possibly fatal complication of acute pancreatitis. Read more…
What Is Hepatitis C?
Hepatitis C is a liver disease caused by an infection with a virus. The liver becomes inflamed and swollen and stops working as it should. Hepatitis C is a serious disease because the liver is needed to remove toxins that build up in the blood. Hepatitis C can destroy the liver and cause cirrhosis. It is the main cause of liver transplants in the world.
After being infected with the hepatitis C virus, 55-85% of people will develop a chronic infection. Once a chronic infection develops, 70% of people develop chronic liver disease — but less than 5% of these people die from the infection. Read more…

What Is Tonsillitis?
The tonsils are two masses of lymphatic (immune system) tissue located at the back of the throat. They produce antibodies designed to help you fight respiratory infections. They are small at birth and gradually increase in size until age 6 or 7. Then they shrink, but do not disappear. When these tissues themselves become infected, the resulting condition is called tonsillitis. Read more…
What Is Tuberculosis?
Tuberculosis, commonly referred to as TB, is a bacterial infection that can spread through the lymph nodes and bloodstream to any organ in your body but is usually found in the lungs. Most people who are exposed to TB actually never develop symptoms. The bacteria can live in an inactive form in the body. Medication can be given to help get rid of the inactive bacteria. However, if the immune system weakens, such as in people with HIV or as we age, the bacteria can activate. In their active state, TB bacteria cause death of tissue in the infected organs, possibly resulting in death. Read more…

Influenza — commonly shortened to “the flu” — is an extremely contagious viral disease that appears most frequently in winter and early spring. The infection spreads through the upper respiratory tract and sometimes invades the lungs.
The virus typically sweeps through large groups of people who share indoor space, such as schools, offices, and nursing homes. The global influenza epidemic of 1918 — which started in a military training camp in Kansas — eventually killed about 500,000 people in the United States and more than 20 million worldwide.
