Myasthenia gravis and swallowing

Why swallowing can change

Myasthenia gravis makes muscles weaker the more they are used. They usually get stronger again with rest.

The muscles for chewing and swallowing are often affected. So a meal can start well and get harder.

What you might notice

• Your jaw tires partway through chewing.
• Swallowing gets harder toward the end of a meal.
• Things are harder later in the day.
• Your voice gets weak or nasal as you talk or eat.
• Tough or dry foods take a lot of effort.

What can help

These are options people with MG describe. Try what fits you.

• Rest before meals, and take breaks during them.
• Eat your main meal when you feel strongest.
• Keep a drink nearby. Moist foods and sauces can make swallowing easier.
• Ask your doctor how your medicine times line up with meals. Many people plan meals around when their medicine works best.
• Never stop or change a medicine on your own. Ask your doctor or pharmacist.
• An SLP can check your swallow and show strategies. You can weigh which ones are worth the effort.

Questions to ask your care team

• When is the best time to take my medicine for meals?
• Would a swallow test be useful? What would it show?
• What should I do if my swallowing suddenly gets harder?
• Could any new medicine affect my muscles?

Breathing matters too

Sometimes MG also weakens the breathing muscles. That is an emergency.

If breathing gets hard, or you cannot clear your throat, get help right away.

When to get help

Get checked soon if you notice any of these. A doctor or SLP can look at what is going on.

You know your own body best. Bring what you notice to your care team, and decide together.

• Coughing or choking when you eat or drink.
• Food or pills that feel stuck.
• Losing weight without trying.
• Pneumonia or chest infections, especially if they come back.
