Is your persistent cough when hungry or full related to myasthenia gravis?
Yes, this could be related to MG. A persistent cough during or after eating can be a sign of swallowing difficulties (dysphagia), which affects 30-60% of people with MG.
When throat and tongue muscles are weakened by MG, food or liquid can accidentally enter your airway instead of going down your esophagus. This triggers coughing as your body tries to protect your lungs.
Here's what might be happening:
* When you're hungry, you may produce more saliva that's harder to swallow with weakened muscles
* When you're full, the effort of eating may have fatigued your swallowing muscles
* Food particles or liquids may be going down the wrong way, causing irritation
This is important to address because:
* It can lead to aspiration pneumonia (a serious lung infection)
* It may cause choking
* It can result in poor nutrition and unintended weight loss
Please talk to your MG specialist about this symptom right away. They can evaluate your swallowing function and suggest strategies to eat more safely, such as adjusting meal timing, taking smaller bites, or modifying food textures.
