Could a persistent cough for 5 months be related to myasthenia gravis?
While MG doesn't directly cause chronic cough, it can create conditions that might lead to respiratory issues. MG affects the muscles used for swallowing and breathing, which could contribute to coughing in a few ways:
- Swallowing difficulties (dysphagia): When MG weakens the throat muscles, food or liquid can accidentally enter your airway instead of your esophagus. This is called aspiration, and it can cause coughing and potentially lead to aspiration pneumonia.
- Breathing muscle weakness: MG can affect the respiratory muscles, making it harder to breathe properly or clear your lungs effectively.
- Dry mouth: Some MGteam members report dry mouth as a symptom, which can trigger coughing. One member found relief using cherry cough drops for dry mouth and swallowing difficulties.
A 5-month cough is quite prolonged and should definitely be evaluated by your doctor. They can determine if it's related to MG complications (like aspiration or breathing issues) or if there's another cause that needs treatment. This is especially important because swallowing and breathing problems can become serious if left unaddressed.
Please contact your MG specialist or primary care doctor about this persistent cough so they can properly assess what's causing it.
