How I Try to Tell the Difference Between MG Fluctuations and Progression

One of the hardest parts of living with Myasthenia Gravis, at least for me, is trying to figure out what’s a normal fluctuation and what might be something more.

MG changes constantly. Symptoms can shift hour to hour, day to day, even minute to minute. That unpredictability can make it really hard to know when to rest and when to ride it out and when to pause and pay closer attention.

I’ve spent a lot of time, as most of us with MG do, asking myself: Is this just a bad day? Did I overdo it? Am I getting sick? Did I sleep enough? Or, is something actually changing that I can't pinpoint?

Honestly, sometimes there isn’t an immediate answer

Over time though I’ve learned there can be a difference between fluctuation and progression. It's helpful for us to notice patterns that will help us better understand which is which.

Fluctuation

For me, fluctuation usually feels temporary, even when it’s frustrating. Maybe I didn’t sleep well. Maybe I did too much the day before. Maybe it’s heat, stress, hormones, illness, or simply that my Mestinon is wearing off.

Symptoms feel stronger than my baseline but they're still recognizable. They usually don't happen all day and they are usually responsive to rest and/or medication like Mestinon. There’s usually some kind of reason I can pinpoint for causing this flare, and usually a return to my baseline when the reason is removed afterward.

Progression

Now, progression feels different. What makes me pause more is when something doesn’t feel temporary anymore especially when symptoms are starting earlier in the day or lasting longer than normal. Or it could be when one symptom becomes two...then three. Or when a symptom you haven't experienced in awhile starts happening more regularly. And especially when recovery doesn’t feel as complete as it used to.

Sometimes it’s subtle at first. Maybe Mestinon used to eliminate all my symptoms and keep me comfortable until the next dose but now I feel it wearing off much earlier. I start noticing weakness creeping in between doses more often instead of just right before the next one and am watching the clock until I can take the next dose.

Sometimes the symptom itself feels more intense or lasts longer or doesn’t fully improve after rest. Maybe I was having a hard time swallowing liquids and now I'm finding it harder to chew and swallow liquids and solids. That’s usually when I start paying closer attention.

The importance of noticing changes in swallowing

Swallowing changes are one I personally watch carefully because they can be easy to dismiss at first. Sometimes it starts small. Liquids feel harder than usual, but solids are still okay. Maybe I notice I need more effort to swallow water.

Maybe I used to take three or four easy sips in a row without thinking and now I naturally pause after one because my throat feels tired. Or maybe swallowing was only tricky at the end of the day before and now it’s showing up earlier.

Then it progresses, so now chewing takes more effort and food feels like it moves slower so meals take longer. I find myself adjusting how I eat without realizing it. That kind of gradual change gets my attention, especially if it sticks around. I try to look for patterns, not panic over moments.

Staying grounded

This part has been important for me. I try not to panic over one difficult swallow, one rough evening, or one bad symptom day even though it's easier said than done. I know that MG fluctuates too much for that. Instead, I do try and look for patterns to determine if it's happening more often or lasting longer. I also pay extra attention to whether rest and mestinon helps or not.

Listening to my body

If something keeps repeating itself, or if my baseline feels like it’s shifting, I pay attention. My body usually whispers before it downright shouts at me, and I’m still learning to pay attention to the smaller clues my body gives before symptoms become obvious.

It's challenging because the signs aren’t always dramatic. Sometimes it’s just noticing: “I’m drinking differently.” “I’m chewing slower.” “My eyes are fatiguing earlier.” “My arms feel heavier sooner.” “My meds don’t feel like they’re lasting the same.” Those little changes matter even when I’m not sure what they mean yet.

Paying attention to your body without spiraling can feel hard. I don’t want to ignore changes that matter, but I also don’t want to analyze every symptom so deeply that it creates fear around every hard moment.

For me, it’s become less about trying to have an answer immediately and more about staying aware and observant. It's also about giving myself permission to rest so it doesn't escalate from a fleeting flare to a more serious progression. I am also still learning to trust myself enough to say, even after 11 years with MG, that something feels different, even if I can’t explain why or how perfectly yet.

With MG, subtle changes are still real, and sometimes simply noticing the pattern early is the most important information of all.
