Is Your Waist Circumference Sabotaging Your Immune System?

This week I’m talking about something called Central Adiposity, or the more fancy term being “Belly Fat”.

Why is this important?  

Well, just like high blood pressure, obesity has an inflammatory component which means it can interfere with the immune response and vice versa.

In a review published in the Proceedings of the Nutrition Society (2012), researchers stated:

Obesity, like other states of malnutrition, is known to impair the immune function, altering leukocyte counts as well as cell-mediated immune responses. In addition, evidence has arisen that an altered immune function contributes to the pathogenesis of obesity. 

When we’re carrying extra weight, especially around the middle, it shifts our biology out of balance because fat cells release pro-inflammatory proteins called cytokines.

In other words, fat cells are a living breathing thing. They’re not stagnant that just sit there and do nothing!

They’re actually endocrine cells because of their ability to secrete hormones and influence cells in other parts of the body, that in many cases, can lead to further weight gain.

Sorry, not exactly the rosiest of scenarios but it’s important that I tell it as it is!

Reducing High Blood Pressure to Support the Immune System.

Last week I chatted briefly about a condition called metabolic syndrome (MetS), and how it’s inflammatory effects can alter the normal functioning of lymphatic tissues involved in the immune response.

Now there are 5 risk factors that fall under the banner of metabolic syndrome, but in today’s post, I’m going to concentrate on High Blood Pressure, also known as hypertension.

First and foremost, something to keep in mind is that high blood pressure is an inflammatory disease that impairs immune function.  That being said, a compromised immune system also leads to inflammation, so it works both ways.

When the immune response becomes dysregulated, it causes the sympathetic nervous system (a fancy way to describe our ‘fight or flight’ stress response), to go into overdrive. This raises our heart rate and blood pressure (which is fine in the short term), but over the long-term, can lead to oxidative damage causing arterial stiffening and hardening of the arteries.

Picture a rusty pipe and this is pretty much what oxidative damage does to our inner piping, so definitely something we want to avoid!
