What is Crohn’s disease?

Along with ulcerative colitis, Crohn’s disease is one of two forms of inflammatory bowel disease (IBD). With both diseases, the immune system attacks the cells in the gastrointestinal tract, causing inflammation, sores, bleeding, cramps and diarrhoea. Crohn’s disease differs from ulcerative colitis in that it can affect almost any part of the digestive system, while ulcerative colitis almost always affects the large intestine. Crohn’s disease can also penetrate the entire bowel wall. Ulcerative colitis only involves the innermost lining of the colon. Both conditions are chronic diseases: they persist over time and, to date, there isn’t a cure for either…

Vaccines: declaring chemical warfare on diseases

Every day our bodies fight off germs, viruses, and other microbes that, if left unchecked, would keep us in a constant state of illness. But there are times and certain diseases that slip past these natural defences. That’s where vaccines come in. What are vaccines?  There are several different types of vaccines but they all act in the same way: by “teaching” your body how to fight off a specific germ. Vaccines are weakened or dead forms of diseases that, when injected, start a series of biological reactions that build our immunity against the specific germ they contain. Vaccines are…

Do you need a shingles vaccine?

Itchy, scabby skin, fluid-filled blisters, fatigue and a fever. Not fun, right? When you’re finally recovering from those painful symptoms of chickenpox, you feel a tremendous sense of relief. But what if the chickenpox virus comes back to visit? Chickenpox is caused by the varicella zoster virus.  When you recover from chickenpox, it may seem as if the virus is gone, but it just becomes dormant in your nerve tissues.

What exactly is Lupus?

Lupus is a chronic autoimmune disease that can damage any part of your body, including your skin, joints or organs. With lupus, your body experiences autoimmunity. This means that your immune system becomes confused and can’t tell the difference between your body’s healthy tissues and “foreign invaders” like viruses, bacteria and germs. As a result, the immune system attacks the healthy tissues and organs, which harms your body in different ways. It may cause inflammation, pain and damage to different parts of the body. Lupus ranges from mild to life-threatening and if treated, most people can live a full life.…

"Put on a jersey, or you'll catch a cold!" Your grandma, mother or aunt has probably told you this at some stage. In fact, maybe you are that mother or aunt? Although you may mean well, this old wives' tale isn't entirely true: the cold temperature won't give you a cold. So why do we associate colds and flu with the winter season?
