Living Better with Dysautonomia (Help #7: The E-word)

Help #7: Exercise

I have been a neglectful blogger lately.
This is in part due to the mild apprehension I felt about writing this exercise post. To start with, POTS/dysautonomia patients are by their very nature exercise intolerant. Exercise intolerance is a crippling symptom of dysautonomia that can make staying in shape about as hard as if you had heart failure. If you suffer from POTS, strenuous exercise will in all likelihood make you feel worse, much, much worse.

That's an encouraging start to this "help" isn't it?

I have a great deal of emotion invested in this topic because I am one of many patients diagnosed with disabling POTS in spite of struggling to exercise regularly. Before my symptoms disabled me, I worked in a lab, went to school, and belonged to a gym. I pushed 3 miles on the treadmill multiple times per week, used all the weight machines (recording my progress on an official-looking chart), and routinely avoided a slimy middle-aged guy who made unwelcome comments and wore unnecessary spandex shorts. I had a gym lock and a duffle bag. In terms of fitness, I was doing everything "right."

But in spite of that, so much went wrong.

About 8 months before I became disabled, I was walking around the track and suddenly felt sick. I decided to go home and barely got in the door before my nausea, dizziness, and cramping got the best of me. A hot shower only made things worse, and I slowly faded out of consciousness while lying in bed. In the ambulance on the way to the ER, my heart rhythm was rapid with excessive PVCs. After receiving a substantial dose of IV saline, I revived, and I was told to take it easy.

This episode is evidence that even those mildly affected by POTS symptoms can have serious episodes triggered by exercise if the proper precautions are not taken. In my case, I was clearly dehydrated. I had not eaten enough before going to the gym. The timing of my menstrual cycle was against me, and I had not gotten enough sleep the night before. For a healthy person, this would not be a big deal, but with underlying POTS, these factors put me in a very vulnerable position. It's because of these important factors that I placed "exercise" as number seven in my list of helps. If diet, sleep, hydration, and other precautions such as pacing are not taken into consideration first, exercise can end in disaster for a POTS patient.

The following exercise tips I have learned by trial and error over the last 6 years. I offer them here as a source of encouragement and in hopes that you won't have to make the same mistakes I did.

Tip 1: Some types of exercises are better for dysautonomia than others.
Simple walking is my preferred type of exercise. However, I have friends who enjoy swimming because of the compressive effect of water on the body's circulation. Recumbent bike riding can be beneficial because of the ability to recline. (Upright biking exacerbated my symptoms.) Additionally, Pilates-type workouts that are done mainly while lying down can allow for greater blood flow to the head. One good DVD for supine Pilates is by Denise Austin.

Tip 2: Some types of exercise are better for YOU than others.
If you don't like bike riding, or if it makes you feel awful, then you will subconsciously avoid it. If you have obstacles to getting to the pool, then you won't go often. If you live in a rainy or cold climate, then walking outside won't be made into a habit. It's best to pick an exercise that you can do immediately if you feel up to it. I am lucky enough to have a treadmill, but there was a time when I didn't have one. I had to get creative, so I walked in a loop around a small apartment. Though simplistic, I was able to do this much more regularly than any exercise which would require me to leave home.

Tip 3: Plan a regimen that is realistic for your current abilities.
When I started a cardiac rehab program shortly after my diagnosis, I was on a beta blocker which lowered my already low blood pressure even further. I was then put on a treadmill and told to move it for 40 minutes. Now, to put things in perspective, I was so dizzy at the time that I could barely hobble from my bed into the bathroom. I had to ride in a wheelchair to get from the parking lot to my cardiologist's waiting room, where I would nearly faint sitting. Trying to do 40 minutes of walking at that time was absurd. I was monitored, so it was safely absurd, but it was a completely unreasonable expectation nonetheless. My blood pressure was regularly in the 80s over 50s, and I had to give a periodic "dizziness rating" to the tech so that she'd know how close I was to passing out. I often left rehab in a wheelchair after lying flat in recovery and felt utterly terrible for days afterward. If you can push yourself to walk 40 minutes, but it destroys you for the rest of the day (or week!), that is not beneficial. It is best to start out with what you can handle, however small that may be - even 5 to 10 minutes once or twice a week!

Tip 4: Stay below your physical limits to achieve consistency.
(This is for all your overachievers out there.)
I am the kind of person who likes to take on a challenge just because it's hard. I like to overcome obstacles, push my limits, and do the most I can possibly do at one time. I'm often tempted to "beat my best ___" time, distance, or speed. This is not helpful when it comes to conditioning with POTS. If I push my physical limit by walking at 2.8 miles per hour but can manage much better at 2.5 miles per hour, it's far superior for me to walk at the slower pace and not exhaust myself. If I start to feel sick after walking for 5 minutes, it's far better to walk for those 5 minutes than to push myself to 10 and then not walk for the next 2 weeks. A good indicator while exercising is to closely monitor your symptoms and your heart rate. Investing in a reliable heart rate monitor can help guide your level of exertion. A blood pressure cuff may help as well.

Tip 5: Skip at least a day between workouts.
The exertion of a workout (or other stressful event) may cause worsened symptoms for the rest of the day and/or a flare over the next few days (also referred to as "post-exertional malaise" or "crashing"). Post exertional-malaise is a proven symptom in patients with chronic fatigue. Our bodies do not return to baseline after a workout like a healthy person. Instead of bouncing back from walking, I can struggle for over 24 hours with increased muscle aches, dizziness, extreme fatigue, and at my worst, a swollen, sore throat (which I had just this week from overexertion). Be aware of your body's limits, and try to pace yourself accordingly by taking days of rest. It's best to give yourself a break between workouts even if you are healthy. It gives your body a chance to heal.

Tip 6: Avoiding exercise altogether is a bad idea.
There have been times when leg lifts in bed were about the extent of my ability to exercise. If you are that sick, I empathize completely and encourage you to check out Yaz exercises or yoga and deep breathing that can be done in bed (my friend has Bed Top Yoga). If you can get up and move around, it will benefit you to do so. Walking around for a sustained interval helps avoid deconditioning, aids circulation, strengthens muscles, and helps mood (which can suffer tremendously under the effects of chronic illness). Quitting all forms of exercise because of POTS is tempting, but in the end, it will not help; it will only make things worse.

Tip 7: Exercise will benefit you but is unlikely to cure you.
Exercise for dysautonomia is highly beneficial when undertaken with the proper precautions. After 6 years of strict pacing and healing, when I am well hydrated, eating nutritiously, and well rested, I find that I can now walk a significant distance (over 1 mile) without feeling dizzy. Even though I have increased my endurance over the years, I still am far from being "cured."

Does mild-to-moderate exercise help manage my condition? Definitely. However, I still suffer from many fluctuating symptoms, including post-exertional malaise. I am still not able to reliably work a job schedule or keep up with a normal life. I still have bad days and weeks stuck in bed. There are times when I curl up in a ball and literally can't move due to fatigue. There are many times I push too hard and suffer for exceeding my body's limitations (just like spending over your bank account's balance will result in hefty fees).

Exercise has been a key part of my recovery, but it is not the only answer. Be realistic in your expectations and be persistent in pursuing physical activity as tolerated. If you miss a week or a month, come back and start again slowly when you can. In that way, you will continue to teach your body how to live better with dysautonomia.

K, I am sorry I haven't read this sooner. I skimmed it but never read it thoroughly. What I want to say to you is that it is so well done and so compassionately done that I am in tears. You need not worry that you didn't do this post 'right'. It is perfect. I love you!

I too have dysautonomia and i have gotten great inspiration from your article. You are truly correct about bouncing back doesn't happen easily for us. Some days just drinking enough fluid is a chore. God bless you in your struggle.

Sorry to hear you have dysautonomia too, Robin. I haven't been active here on my blog in a while, but today I just added a list of links to more recent writings called "The Healing Process." The series details new things I've learned about improving my health since I wrote this exercise blog in 2011. I hope it helps to know you're not alone. It is a constant battle for us to figure out what works for us and what doesn't!
