Difference Between Irritable Bowel Syndrome (IBS) and Inflammatory Bowel Disease (IBD)

Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) are two distinct gastrointestinal disorders, eventhough the differences between the them can be confusing for many people.

Irritable bowel syndrome (IBS) 

IBS is also known as spastic colon, irritable colon, mucous colitis, and spastic colitis. IBS is a group of intestinal symptoms that typically occur together. The symptoms  last at least three months for at least three days per month.

The risk of developing IBS was double for person with anxiety and depression.

IBS pain may feel like cramping. With this cramping, you will also have at least two of the following experiences:

1. some relief of pain after a bowel movement
2. a change in how often you have a bowel movement
3. changes in the way your stools look

There is no cure for IBS. Treatment is aimed at symptom relief. 

Inflammatory Bowel Disease (IBD) 

IBD is a term for two conditions (Crohn’s disease and ulcerative colitis) that are characterized by chronic inflammation of the gastrointestinal (GI) tract.

Difference between Common Cold and Influenza ( Common Cold vs Flu )

Common cold and influenza are both respiratory illnesses but they are caused by different viruses. 

Influenza viruses are single-stranded RNA viruses belonging to the Orthomyxovirus family. They can mutate quickly, which makes development of effective vaccines and antiviral agents a challenge. Influenza A viruses cause most outbreaks and are more pathogenic than other types of influenza viruses. In the spring of 2009, a triple-reassortant strain of influenza A (H1N1) that contained swine, avian, and human genes caused several outbreaks in Mexico and the United States; new cases were soon reported worldwide. On June 11, 2009, WHO declared a global pandemic based on 30,000 cases of H1N1 influenza in 74 countries.

Common Cold can be caused by more than 200 types of viruses. However, the rhinovirus and coronavirus are the most common causes. 

• Rhinovirus is most active in early fall, spring, and summer (10%-40%). They rarely make you seriously sick. 
• Coronavirus is most active in the winter and early spring (20%).
• RSV and parainfluenza (20%). They sometimes lead to severe infections, like pneumonia, in young children.

On the other hand, research suggests that stress and allergies that affect your nose or throat may raise your chances of getting infected by a cold virus. There is no evidence that you can get a cold from exposure to cold weather or from getting chilled or overheated.

Stress and Psoriasis

Psoriasis is chronic skin disease that has high impact to patient's quality of life. In the last decade, many scientists doing some research to prove the relation between psoriasis and mental health problem. The result is very unique. Psoriasis has stronger association with mental health than other skin disease. Psoriasis can be maintained and exaxerbated by an underlying stress condition within a vicious cycle. You can look to the scheme below for understand more about the cycle.  

Stress condition will activate our nerve system to release stress hormon that induce inflammatory factor. This factor will affect epidermal barrier which is important mechanism of psoriasis. But if you look more to the scheme, we can also conclude that psoriasis may lead or worsen stress condition too. Chronic itch, disfigurement, and stigmatization lead to stress. 

Mind and our body has really strong connection. It's really important to keep our body and mind healthy.
