The traitor within: Navigating the internal triggers of myasthenia gravis
When I begin to recognize them, I understand my body more compassionately
Written by |
Living with myasthenia gravis (MG) means learning that not all triggers come from the outside world. Some of the biggest ones come from inside my own body, the traitor.
Hormonal shifts, sleep disruptions, and internal rhythms can shape my symptoms long before I’m aware danger is afoot. These triggers tend to be quieter than heat, stress, or overstimulation for me. They don’t announce themselves. They just show up in the way my muscles feel heavier, my breathing feels more strained, or my eyelids start to droop before the day has even begun.
For years, I didn’t understand why some mornings felt impossible before I even got out of bed. It took time, and a lot of lived experience, to realize that my body has its own internal cycles, and MG responds to them whether I want it to or not.
Sleep, sickness, and hormonal changes
Hormones are one of the biggest culprits. I used to think hormonal shifts were just an emotional thing or related to my “cycle.” But hormones aren’t just feelings; they’re chemistry. And chemistry affects muscle strength, fatigue, breathing, and the amount of reserve I have on any given day. Cortisol, for example, increases with stress. But it also rises with pain, illness, and even anticipation. I’ve had days when I woke up already weak, only to realize later that my body had been riding a cortisol wave I wasn’t privy to.
These hormonal shifts don’t always feel dramatic. Sometimes they’re subtle and present as a heaviness in my jaw, a tightness in my chest, or a sense that my muscles are working harder than they should. Other times, they hit like a sudden drop-off, and everything changes in the span of a few breaths.
It used to frustrate and anger me. It still does to a lesser degree, but at least now I understand that they’re often tied to internal rhythms I can’t see, but can learn to anticipate.
Sleep, or lack thereof, is another trigger that carries more weight than I ever expected. My circadian rhythm and delta waves during sleep are both disrupted, which can make my symptoms the stuff nightmares are made of. These internal sleep dysregulation triggers tend to wreak more havoc than common external factors that may affect a good night’s rest. I’ve had mornings when my diaphragm felt tired before I’d even spoken a word, or when my legs felt shaky just walking to the kitchen. There are nights when I sleep well and still wake up weak because “sleeping well” meant I was auditioning for the role of “Sleeping Beauty” for 14 hours. MG is a fickle beast and doesn’t follow simple rules. Rude.
Over time, I’ve learned to recognize the patterns: the way a restless night often leads to a heavier morning, or the way a string of crappy sleep can stack symptoms until my body finally forces me to stop.
Illness, even a mild one, can also throw everything off. While the cause for the illness may be external, the way the body reacts is internal. A simple cold, a headache, or even seasonal allergies can make my muscles feel like overcooked spaghetti.
My body works harder to fight off anything that doesn’t belong, which then leads to friendly fire as it ignores the treatments that keep my body’s immune response in check, and it begins to attack itself.
Without explanation or categorization
And then there are the rhythms that don’t fit into neat little boxes that bring days when my body revolts for no clear reason. I’ve learned that these days often have explanations I can’t see, and I just have to accept them for what they are. My body is obviously trying to tell me to chill out and slow down, so I do my best to listen.
Understanding these triggers hasn’t made MG predictable, but it has made it less mysterious. I’ve learned to pay attention to the small cues and subtle shifts that tell me my body is working harder than I think. I’ve learned that managing MG isn’t just about avoiding external triggers. It’s about honoring the internal ones, too.
These patterns aren’t always obvious, and they’re rarely consistent. But once I start to recognize how they look for me, I begin to understand my body in a deeper, more compassionate way. I learn to pace myself, not just in response to what the world demands, but also to what my body needs. I learn to rest before I crash. I learn to listen before the symptoms roar.
This knowledge becomes power because learning to recognize them becomes its own kind of strength.
