What is Type 2 Inflammation, really?

Quick Note: I’m sharing this based on my personal experience and research, but I’m not a medical professional. This post is for informational purposes only and isn’t medical advice. You can find my full medical disclaimer at the bottom of this page.

What is Type 2 Inflammation really? That’s a question that I was asked today. Well, I’m going to tell you about it as best as I understand myself. To tell you the truth, I’m still struggling with fully understanding the clinical explanation of Type 2 Inflammation. There is a lot of medical terms involved that, despite my extensive experience in being a medically screwed up person, I have never heard before. I am still working at fully understanding how everything ‘clinically’ works. But, usually I am pretty decent I think at analogies, so hopefully I can offer you an analogy that will be able to explain in more layman’s terms how Type 2 Inflammation is interacting with your body.

Before I get too carried away, I will warn you that my analogy is filtered through the medical conditions and symptoms that I personally experience as a result of having Type 2 Inflammation. I have or have had allergies, nasal polyps, asthma and I’m pretty sure I have mild Eosinophillic Esophagitis because I also have weird acid reflux kind of issues. I also get rashy and get this feeling like I have hives inside of my face.

Imagine a candle. Like one of those little skinny ones that you would put on the top of a birthday cake. You’re the candle. Allergens, irritants and chemicals are all things that set fire to your candle. When a ‘flame’ is lit in a regular, healthy immune system, the immune system responds by metaphorically blowing out the flame before any real damage can be done to the candle.

An allergen is something small and innocent that shouldn’t even be a big deal. When a person has allergies this means that the immune system is overreacting in the way that it responds to the threat. Kind of like trying to put out the flame of a little candle with a fire extinguisher. The candle flame being the ‘allergen’ and the fire extinguisher being your immune system.

When you have issues with Type 2 Inflammation, instead of a fire extinguisher, your immune system called in the ENTIRE fire department to put out the flame of a tiny candle. Then, it’s not even like they show up, put the fire out and leave. Oh, no. They hang around, get in the way and spray things seemingly randomly as if they are afraid of a fire breaking out spontaneously. At the same time however, they also run around lighting fires rather than just putting them out. It’s kind of like a bunch of pyromaniacs running out and forming a fire department so that they can both set fires and put them out. Almost like they want to practice fire drills for threat protection, but they do that by setting you on fire. So your immune system reaction is going completely overboard in its threat protection to the point where instead of helping you, it feels like it’s killing you. This results is both external and internal attacks, leaving you feeling not so much like you are burning the candle at both ends, but rather you are the candle and you are melting, inside and out!

As a result of the internal and external attacks, even when you put yourself in a figurative bubble, trying to protect yourself from getting set on fire, you can still be ‘melting’ and having a reaction because your fire department(immune system) is completely out of control; either using a fire hose to put out a candle fire, or just drowning you in the water.

This then results in diagnosis like allergies, asthma, eczema, food allergies, Eosinophillic Esophagitis, and nasal polyps. It can lead to symptoms including sneezing, nasal congestion and draining, rash, itching, sinus inflammation, itchy eyes, inflammation of the esophagus, eczema, nausea, vomiting, and abdominal discomfort, among others.

Type 2 Inflammation or T2I for short, is a full body, systemic ‘overdrive’ of the immune system. The immune system has these little proteins called cytokines. The cytokines are supposed to work like an internal radio system for your immune system. They send out the signals that pass along messages like how to fight off parasites or that there is skin needing repair or an infection forming. For people with T2I, it’s kind of like these little messengers have gone from being clear and direct about what needs to be done and instead are auditioning for the role of a fast talking auctioneer, throwing out messages so hard and fast that the messages are getting garbled and confused, leading to an overreaction in an effort to solve the problem. It’s almost as if it gets to a point where the body stops hearing messages like, repair this cut, and only hears ATTACK EVERYTHING! Next thing ya know, you can find yourself buried under an over abundance of symptoms and are left feeling like something the cat drug in and you don’t even know what set it off.

The good news is is that there is hope. We may not be able to send our immune system back for a new one, but there are lifestyle changes that we can make and medications available to start slowing our fast talking auctioneers down so that our bodies can stop living in full fledged fight or flight mode. For a long time, the medications were limited to ones that specifically targeted the symptoms. Like antihistamines for allergies and lotion and steroid creams for the eczema. But in recent years other options are becoming available. The one that I am most familiar with is Dupixent. Dupixent works by inhibiting the signals of two key proteins in the T2I process. By blocking these signals, it stops that high flow ‘overdrive’ of information that pushes the body to such extreme responses. Although these treatments cannot make cure T2I, they can greatly improve quality of life for some of us who have been buried beneath the weight of our symptoms, unable to find relief through things like antihistamines or creams.

    Mel, I like your analogy. I have bad nasal allergies only so I am probably in the area of the big fire extinguisher for the candle, doesn’t involve the rest of my body, miserable nonetheless! I was wondering, what improvement has Dupixent made in your life specifically?

    1. Mel Seeley Avatar

      Sherri, thank you, I appreciate hearing that. Even allergies on their own can be plenty difficult to deal with. Especially the ones that are the hardest to avoid. As far as the Dupixent, it has helped with a lot of the symptoms that I was having. Before I started Dupixent I basically couldn’t breathe through my nose at all. Between having nasal polyps and the nasal inflammation and congestion, my nasal passageways just didn’t allow enough air through to breathe. Now, most of the time I can breathe through both sides of my nose. I still have times where I have break through symptoms or my allergies are being difficult, but even then I can still usually breathe through at least the one side and it doesn’t usually last very long. At least as long as I don’t over expose myself to things that I know will aggravate my body. But before, my body was so aggravated ALL THE TIME that I couldn’t even tell what made it worse most of the time. I also used to have what I called ‘allergy attacks’, during which I would feel like I had hives inside of my face, mostly where my sinus passages are. Now, I get a little itchy now and again but NOTHING like it was before. During the allergy attacks I would just pour nasal drainage. I might go through a box of tissues in a day. Sometimes even more than that. The attacks would often last for hours. Leaving my face feeling raw and sensitive to the lightest touch. Now, most days, I go through maybe a half dozen tissues and I don’t feel like a hair on my head touching me is going to send me through the roof. During the allergy attacks I would sneeze a lot. I want to say a couple dozen times in the course of an attack. And I would have these attacks at least once a day on most days. Now, I go days and not sneeze. Not today unfortunately, but still, it was only twice. These allergy attacks would often lead to an abundance of drainage down the back of my throat to the point that I would feel like I was drowning in it. That would lead to me coughing up the drainage and feeling like I couldn’t breathe. It would also trigger my asthma quite frequently which was made worse by the heavy drainage. Now I still have milder issues with the drainage, but I don’t usually feel like I am drowning, and it is a lot easier to resolve. I had brain fog what felt like ALL THE TIME. Thinking was a constant struggle and took a lot of effort. Now, I feel like there are parts of me waking up that I had forgotten even existed. Which some nights lead to me laying up bed unable to sleep because it feels like my brain is trying to think about EVERYTHING in the universe ALL AT THE SAME TIME. That has taken some adjusting to, but in a good way. I used to feel exhausted ALL THE TIME. Now, I am getting things done that I haven’t had energy to do in years. I used to have to take 2-4 recovery days every time I tried to work on something in my house. Now I might work 3-5 days in a row before I need a recovery day, depending on what I am doing. I don’t seem to react as severely to most things as I used to. Going forward I think that things will continue to improve. I’ve been on Dupixent for 2 years now and I have slowly continued to improve during that time. I think I might have been further along, but I let the doctors talk me into allergy shots and that actually made my symptoms worse. Hopefully as I get further out from that, things will continue to improve.
      Thinking about your allergy situation, I find myself wondering, do allergy medicines actually seem to make a difference for you? Because that was one thing that looking back I really realized. When I took allergy medicines before Dupixent, they really didn’t seem to do much. But now when I take them, it really does help. I remember when I first noticed that. I was like, ‘Wait a minute. Allergy medicines actually do stuff. What??!” Lol. I don’t know if that is common, but that is something that I noticed about myself.
      I am thinking about putting together a post about the top items that I have tried for allergies that do seem to make a big difference for me. So keep an eye out for that. Hopefully we can find something that will make a big difference for you. Praying for answers and healing for you.

        Thank you so much, we have much in common – I too have what I call “allergy attacks” and you described it perfectly, going through a box of Kleenex, tons of nasal production, nonstop, sneezing, that’s what drove me to the allergist in 2010 who recommended allergy shots (like YOU had) which made my allergies WORSE (like YOU) – They said I was HYPERsensitized instead of DEsensitized to my allergens (mold, dust, dogs), so at that point I went to U of M Ann Arbor Allergy clinic and was diagnosed with 3 types of rhinitis, vasomotor rhinitis, allergic rhinitis, etc. and given 2 nasal sprays which improved my life greatly for about 10 yrs then…Covid changed everything and I’ve been gradually getting worse. Nasal sprays are no longer cutting it, having those “allergy attacks” once a month or so and, YES, one allergy med in particular ALWAYS calms down my “fire extinguisher immune system” – that is Walgreens Allergy Relief D ( chlorpheniramine maleate 4 mg, pseudoephedrine 60 mg) – it’s an old antihistamine and I don’t want to take it every day – I have an appt with an ENT in Feb. As far as Dupixent, I don’t understand how that is helping because I thought it was for eczema? – interesting! I am happy for you!! Any side effects?

        Sherri, you are most welcome! Any knowledge I can offer, I will. I know how absolutely miserable it is and can be. It sounds like you have been through a lot trying to get your allergies under control as well. It’s interesting that you would mention Chlorpheniramine maleate. I take that as well, but I buy just the antihistamine without the added pseudoephedrine. I get it on Amazon in a big bottle for 10-12 dollars usually. I find that just taking the antihistamine doesn’t really make me drowsy by itself. Just because it is an old antihistamine doesn’t mean that it doesn’t work better than the newer ones. So the likely reason that you think of Dupixent in conjunction to eczema is because all of the commercials for it are targeted to people with eczema symptoms. But really it works for a bunch of different symptoms that are all linked back to Type 2 Inflammation. Among the symptoms are Eczema, of course, nasal polyps, Chronic Rhinosinusitis with nasal polyps, some food allergies and Eosinophilic Esophagitis. I suspect as time goes on, they may find even more conditions that are caused as a result of type 2 inflammation. The Dupixent address the type 2 inflammation and as a result the symptoms stemming from the type 2 inflammation are decreased. As far as side effects go, for the most part I have not noticed any side effects. Any issues that I may have had from Dupixent have been so mild by comparison to the allergy symptoms that I haven’t even noticed them. I’m going to include the link for you for the antihistamines in case you are interested in trying that option. I believe they are also available at Walmart. Just not in the big bottle. I am working on a post outlining the top things that I have found to help with the allergy symptoms so hopefully I will have that ready soon.

    Thanks – what is your Dupixent dosage?

    1. Mel Seeley Avatar

      Well, Dupixent is an injection that I just have to take every other week. One thing that I would recommend for anyone starting Dupixent to request the syringe option rather than the pen. The pen you push down and it autoinjects and I hate it. If it flows in that fast it kind of burns. But the syringe allows you to control the flow and inject it slowly. Most of the time when I can slowly control the flow, I barely even feel it going in.
