As International Ehler's Danlos Syndrome awareness month comes to a close I wanted to talk some more about how Ehlers Danlos Syndrome affects the body in ways you might not have expected, and specifically the way it affects mine. I posted part 1 already, and here is part 2. EDS, as I've explained in many previous posts, is a group of genetic defects that causes the body to improperly make collagen, potentially causing all sorts of issues where collagen is found... which is most of the body.
First off, I wanted to say that it is really frustrating that I don't have a regular doctor managing my care who can explain to me which of my issues are connected to EDS, and who to go to for help with those issues, and the direction to go in. While I went to the EDS expert in my country, visits to her are really expensive and not something I can do regularly, so a lot of what I am learning about my body and how it is affected by EDS is things I've had to piece together, also from other members of the EDS community, and my own research.
It sucks that it is like that, but Ehlers Danlos Syndrome, despite being discovered in the early 1900s, is only now being studied more in depth to find out the many ways it affects the body. However, that means, at least, in future generations, or maybe in my lifetime, other people will have the information more readily available, and maybe even the average general practitioner will be more knowledgeable and can manage an EDS patient's care like I wish mine could.
Because much of this is research I've had to do myself, and I can't just link you to article after article on the topic, this post will be much more "sciency" than previous posts of mine.
So here are some more ways in which Ehlers Danlos Syndrome affects the body.
Bones
Bone density: The EDS specialist I went to referred both myself and my son to get a bone density scan. I didn't understand why, at the time, but looked it up and found that people with certain types of EDS tend to have lower bone density than the norm, and should be regularly checked for osteopenia from a younger age than you'd usually check them. Fortunately, regular exercise helps with bone mineralization, so this can hopefully be avoided with EDS safe exercise.
Breaks: I never broke any bones in my life, because every time I fall or do something to injure myself, my joints and muscles give way instead of bones, which is why I've had more sprains than I can count in my life,. My son, Ike, on the other hand, has broken 7 bones by the age of 14, and his first break was only at 8 or 9, so he's averaged one break a year for the last many years. I would think, therefore, that his tendency to break would mean he doesn'd have EDS, because what do bones have to do with collagen, but I was actually very wrong. It is not just cartilage in the joints made of collagen; your bones are also made with a lot of collagen. So it would make sense that faulty collagen would lead to bones breaking, not just dislocations and sprains.
It was a little hard to find research on this (and you have no idea how many studies I looked up and read but, in addition to having lower bone density, people with EDS tend to have a higher rate of fractures than the norm. The reasons for this is varied, but one of them is that people with EDS tend to have smaller cortical bone area and thickness, the compact and dense outer layer of your bone, which is what strengthens the bones. Another thing that causes bones to break more easily in people with EDS is that they tend to fall a lot more, because of joint instability.
Proprioception: But with my son, it wasn't just falls that caused breaks, it was his extremities (toes and fingers) getting hurt because of smashing them into things or dropping dangerous things on them because he didn't realize his toes were there. This, too, is connected to EDS, because people with EDS have worse proprioception, the awareness of where the body is in space. (I also have terrible proprioception and it's part of why I fall a lot, as well.)
Why is proprioception worse in people with EDS? Well, fascia is a network of connective tissue that surrounds and connects most things in your body, such as muscles, bones, and organs. We have proprioceptors, receptors in the body that detect information about body position and movement, and they communicate with the nerves and brain through the fascial network. This doesn't work properly in people with EDS because fascia is made up of... you guessed it... collagen. Fortunately, there are ways to help with this, such as physical therapy including repetitive muscle vibration (using various tools) and even using kinesiology tape. This is fascinating and gives me hope that maybe I can improve mine, and maybe my son's as well, so he doesn't break as many bones.
Spine Curvature: People with EDS often have scoliosis (S shaped spine) or kyphosis (forward curvature of the spine), a different incorrect curvatures of the spine. There's a specific type of EDS called kyphoscoliotic EDS which has both severely, but others can have less severe types. I have kyphosis and 2 of my kids have been diagnosed with scoliosis, though fortunately not severely. The EDS specialist recommended that I do Schroth style PT to help with that, and my physical therapist is helping with that.
Digestive Tract
One of the most common ways EDS affects the body is in the digestive tract. Some studies suggest that between 50% and 90% of people with EDS have gastrointestinal issues!!! Your digestive tract is chock full of connective tissue, and that would explain why these are so prevalent.
GERD: Probably the most common type of GI issues connected with EDS is GERD, when the sphincter at the bottom of the esophagus doesn't work properly and allows stomach acid into the esophagus, which causes heartburn, regurgitation, and chestpain. Over 50% of people diagnosed with hypermobile EDS have GERD according to one study. This is because the sphincter is made up of collagen, specifically the type of collagen that is faulty in hEDS and sometimes in Classical EDS as well. I have GERD, and have been on medication for it for a year, which is great. I didn't have so much burning as much as feeling like I was going to puke, but meds helped that go away.
IBS, irritable bowel syndrome, is also common with EDS, which can cause constipation, diarrhea, nausea, bloating, and gas. Up to 62% of people with hEDS have IBS. I got diagnosed with IBS as a kid, and it is a pain and a half, and is part of the reason I avoid certain foods, because they irritate my already irritable stomach.
Delayed gastric emptying, with the worst being gastroparesis, partial paralysis of the stomach, with lots of negative symptoms, is also common among people with EDS, but fortunately I am not one of those.
R-CPD Now this last one is not something I've seen any studies on, and never have been officially diagnosed with, because I didn't even know it had a name, or that it was an official thing to even bring up with my doctor. No Burp Syndrome, officially called Retrograde Cricopharyngeus Dysfunction (R-CPD/No Burp Syndrome), is a relatively rare condition in which the cricopharyngeus muscle doesn't relax to allow air to exit the stomach and esophagus, which, as the name makes obvious, makes you unable to burp, something necessary to allow excess air to escape the body. Because of this inability to burp, people with R-CPD have loud gurgling noises, bloating and discomfort, and excessive flatulence. As you can imagine, this is quite irritating.
I have not seen any studies that connect R-CPD to Ehlers Danlos Syndrome (though I did find a reddit thread on it) but that is understandable because they are both relatively rare, with RCPD even more rare as far as I can tell... but I am including it here because it is quite clear to me that it is connected. Sphincter issues are often related to EDS. GERD is caused by an issue with the lower esophageal sphincter. Delayed gastric emptying, as mentioned above is a common side effect of people with EDS, and is connected to an issue with the Pyloric sphincter at the bottom of the stomach. People with EDS also commonly have issues with the anal sphincter. Sphincters are ring shaped muscles that act like valves throughout your body, and contain connective tissues. The cricopharyngeus muscle has a lot of type I collagen, which patients with Ehlers Danlos Syndrome (specifically hEDS and also classic EDS) make improperly, so according to my logic, this would be a clear cause of it for me, and maybe other people as well.
Eyes
Eye issues of all types are common with Ehlers Danlos Syndrome because eyes are... you guessed it, built up of connective tissues (80% collagen, if you can imagine). My eyes have been causing me problems for the past few years. I've worn glasses since I was 9, but since I was 12 my prescription had stayed more or less the same, around -2.00 but suddenly at the age of 32 my prescription changed to 3.00/-3.25, and then 4 months later they jumped to 3.5/4.0 in addition to needed reading glasses/progressive lenses at quite a young age (usually presbyopia, having difficulty with close up vision as you age, only starts up at around 40), and every 4-6 months after that my prescription changed and I needed new really expensive progressive lenses again! Now, 4 years later I am over 5.00 and my presbyopia has gotten worse as well. I didn't have an explanation as to why this was happening- my optometrist was flummoxed, and the ophthalmologist I went to was flummoxed as well.
Kerataconus. However, after going to the EDS specialist, she sent me to an eye specialist who tested me for a few more things and ruled out some serious things, but brought up the possibility of kerataconus, where the cornea (made of collagen) gets more and more misshapen, which can cause eyesite to get rapidly worse, and is a frequent comorbidity of EDS. If I have it, it would be in the early stages, but she wanted me to get tested every 6 months and bring my optometry records over the past few years.
If that isn't the issue, I'm not sure what exactly is causing this, but I'm sure it has something to do with my collagen. But even if I had keratoconus, that doesn't cause presbyopia.
There is more than one theory about the cause of presbyopia. One is that the lens hardens and thickens as you age, and then cannot change shape as needed to focus on objects close up. Another theory is that it is caused by issues with the ciliary muscle, found behind the iris, which contracts and relaxes to help the lens change shape and bend light rays to focus on the retina to see nearby. The ciliary muscle is made of a lot of collagen... if that stretches out... then it can't properly reshape the iris as needed...
Dry Eyes- Dry Eye Disease is also prevalent in many with Ehlers-Danlos syndrome, especially hEDS. This is because of a dysfunction in the tear film layers, likely because of issues with the tear gland, which are supported by collagen. I've had dry eyes my whole life, and it has caused me pain, and it is why I blink a lot, and it is why, when I wore contact lenses, I had to wear ones for dry eyes. Sometimes my vision is even affected by it, and I need to blink a bunch of times to be able to see clearly.
Last time I was at the dentist he pointed out that I had receeding gums and when I mentioned EDS he said that can be a side effect of EDS, because the gums are made of... connective tissues. In fact, there is a specific type of EDS called periodontal EDS whose main symptoms are gum disease. My youngest kid, the one with an official EDS diagnosis, complained to me that her adult teeth felt loose. That was very concerning for me until I looked at her mouth and saw that she also had receeding gums. The dentist told me to use super soft bristled toothbrush and toothpaste for sensitive gums, so I gave that to my daughter as well and its already improving.
My youngest, Rose, is the one who dislocates and subluxes the most. (That is why she has the official EDS diagnosis; she meets all the necessary criteria for an hEDS diagnosis.) If I didn't know about EDS, I wouldn't know how to help her. A few times recently she was just sitting watching a movie and then started screaming and crying in pain, saying that her shoulder/upper arm hurt as much as when she broke it. I knew that even if she hadn't done anything, her hypermobility means she can sublux things even by just moving her arm or rolling over or breathing hard (just like me) and I knew something was actually wrong.
Honestly? For me. For you. For people diagnosed with EDS and people who may have EDS but don't know about it. When I was writing it, I learned so much more, because I knew certain things were connected to EDS but didn't know why, so when I was researching the reason EDS affects those issues, I was then able to also do further research to learn how to take care of these issues.
If you have EDS also, maybe you will be able to get help for these issues, now that you know the cause of them.
If you have any or many of these issues but hadn't actually thought about EDS as a possibility, maybe it'll help you pursue a diagnosis, as I did after hearing my friend talk about her EDS, which has allowed me so much improvement in my life. The same goes with your kids, if they show any of these issues.
And lastly, if you don't have any of these issues, learning about them may help you understand more what people are going through, helping you be more empathetic, and not thinking that people are making a big deal out of nothing, even if it appears that way from the outside.
