That's a really important question. While asthma itself isn't a listed trigger for a myasthenic crisis, anything that stresses your respiratory system can make breathing harder when you already have MG-related muscle weakness.
With MG, the muscles that control breathing are already potentially compromised. If your airways are also inflamed or constricted, your body has to work even harder to breathe, which could increase the risk of a crisis. Warning signs that a myasthenic crisis may be developing include:
- Shortness of breath
- Increased difficulty swallowing
- Increased muscle weakness
- Sleep apnea
If you notice any of these worsening — especially during a flare-up — reach out to your doctor or care team right away. Don't wait it out.
It's also worth noting that some medications used to treat respiratory issues can interact with MG, so always check with your neurologist before starting any new medication.
