Sequestration of iron in the liver with chronic immune activation: This means that when your immune system is constantly activated due to ongoing inflammation or infection, your body tends to store more iron in the liver rather than releasing it into the bloodstream where it can be used. This happens partly because of the increased production of hepcidin. So, even though your body might have enough iron stored, it may not be able to access it efficiently, which can worsen anemia.
Hepcidin: Think of hepcidin as a body guard for iron in your body. When your body senses inflammation or infection, it produces more hepcidin. Hepcidin’s job is to regulate the amount of iron in your bloodstream by controlling how much iron gets absorbed from your food and how much gets released from your body’s iron storage. So, when hepcidin levels go up, it can lead to less iron being available for use in your body, which can contribute to anemia.
Anemia of chronic inflammation: When your body is dealing with a long-term or ongoing inflammation, it can affect your red blood cells. Immune responses to bacteria triggers your body to produce certain substances that interfere with the normal process of making red blood cells or can cause them to break down faster. This can lead to a condition called anemia, where you don’t have enough healthy red blood cells to carry oxygen around your body efficiently.
Bacteria and Parasites Crave Iron
When we talk about bacteria and parasites, think of them as tiny organisms that can cause infections in your body. These little troublemakers need iron to survive and grow, just like we do. But here’s the catch: they can’t make their own iron, so they have to get it from somewhere else.
Now, your body has its own way of storing and using iron, but when it’s dealing with ongoing inflammation (like from an infection or other health issues), things get a bit complicated. One of the ways your body responds to inflammation is by producing certain substances, like hepcidin, which we talked about earlier. Hepcidin helps control the amount of iron in your body, and when it goes up, it can make it harder for bacteria and parasites to get the iron they need.
But these sneaky little invaders have their own tricks. Some bacteria and parasites have developed ways to actively seek out iron in your body, even when there’s not much to go around. They can produce special molecules or enzymes that grab onto iron and snatch it away from your body’s defenses. This means they can thrive and multiply, making the infection worse.
Now, how does this relate to anemia of chronic inflammation? Well, remember how inflammation can increase hepcidin levels? This can lead to less iron being available for your body to use, including for making red blood cells. So, even though you might have enough iron stored up, it’s not getting to where it’s needed. Plus, when bacteria and parasites steal iron for themselves, it makes the situation even worse, contributing to the development of anemia.
In simpler terms, bacteria and parasites are like iron thieves, stealing the iron your body needs. When your body is fighting off inflammation, it can’t use iron properly, which can lead to anemia. So, it’s like a double whammy – inflammation messes up your iron levels, and these pesky invaders make sure even less iron is available for your body to use.
