What foods should I avoid if I have myasthenia gravis?

Difficulty chewing and swallowing are common issues for myasthenia gravis patients, which can be affected by food choices. Understanding what foods to avoid is an important aspect of managing symptoms and supporting overall health.

Quick Summary

This guide details foods and supplements to limit or remove for effective myasthenia gravis management. The goal is to reduce fatigue, prevent swallowing problems, and avoid medication interactions.

Key Points

• High-Sugar Foods: Avoid sugary drinks and snacks that cause energy spikes and crashes, worsening fatigue.

• Processed and High-Fat Foods: Limit processed, fatty, and fried foods that can cause weight gain and increase inflammation.

• Tough and Dry Foods: If you have swallowing issues, avoid tough meats, dry crackers, and bread, which can be hard to chew and swallow safely.

• Magnesium Supplements: Do not take magnesium supplements without a doctor's supervision, as they can interfere with nerve function and potentially trigger a myasthenic crisis.

• High-Salt Foods: Reduce salt intake to manage fluid retention, a potential side effect of corticosteroid medication.

• Alcohol and Caffeine: Minimize or eliminate alcohol and caffeine, as they can worsen muscle weakness and potentially interfere with medications.

• Food Consistency Matters: Focus on soft, moist foods and purees to make chewing and swallowing easier and safer.

Diet and Myasthenia Gravis: Foods to Avoid

Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disease characterized by fluctuating muscle weakness and fatigue. There is no specific MG diet, but certain foods can worsen symptoms or interfere with medications. A thoughtful approach to nutrition, including avoiding specific food types, can be a valuable part of your overall management strategy. This guide will detail key dietary restrictions and offer practical tips for making safe food choices.

Foods That May Worsen Fatigue

Fatigue is a hallmark symptom of MG, and certain dietary patterns can contribute to energy spikes and crashes. A diet high in processed foods and simple sugars, for example, can lead to these energy fluctuations, exacerbating feelings of weariness.

• High-sugar foods: Sugary snacks, sodas, and energy drinks can cause a rapid increase and then crash in blood sugar, increasing fatigue. It is best to choose nutrient-dense foods that provide sustained energy instead.
• Processed and high-fat foods: These can contribute to weight gain, which puts more strain on your muscles and can worsen fatigue. Examples include fried foods, fast food, and fatty snacks. A high intake of saturated fats may also increase inflammation, which can aggravate autoimmune conditions.
• Alcohol: Excessive alcohol consumption can interfere with muscle function and interact negatively with MG medications. It is generally recommended to limit or avoid alcohol completely.

Foods to Avoid if You Have Swallowing Difficulties

Many people with MG experience dysphagia, or difficulty swallowing, which can make certain food textures dangerous. Avoiding tough, dry, or crumbly foods is important to prevent choking or aspiration.

• Tough meats: Chewing tough meats like steak can fatigue the jaw muscles, making it difficult to complete the meal. Softer protein options, like fish or minced poultry, are better alternatives.
• Dry, crumbly foods: Crackers, cookies, chips, nuts, and popcorn can break into small, dry particles that are easy to aspirate. Foods that hold their shape and moisture are safer choices.
• Bread and mixed-consistency foods: Dry bread products, such as bagels and sandwiches, can be challenging to chew and swallow. Similarly, mixed-consistency foods like cereal with milk or chunky soups can pose a risk, as the thin liquid can travel down the throat faster than the solid pieces.
• Thin liquids: For some, thin liquids can be difficult to control during swallowing. In these cases, a speech-language pathologist may recommend thickening liquids to a safer consistency.

Foods That Can Interact with Medication

Certain dietary components can interfere with the effectiveness or side effects of medications used to treat MG. This includes steroids and anticholinesterase drugs like Mestinon.

• High-salt foods: Corticosteroids like prednisone, a common treatment for MG, can cause fluid retention. Limiting salt intake by avoiding processed meats, canned soups, and salty snacks is essential to manage this side effect.
• Magnesium supplements: Magnesium can interfere with nerve-to-muscle communication and may worsen muscle weakness, especially in high doses. Intravenous magnesium is particularly risky and can trigger a myasthenic crisis. Patients should avoid magnesium supplements and consult their doctor about magnesium-containing medications, like some laxatives.
• Spicy and high-fat foods: For those experiencing diarrhea or stomach issues from anticholinesterase medications, spicy, high-fat, and greasy foods can further aggravate the digestive tract.

Alcohol	Beer, wine, liquor	Water, herbal tea, fresh juices	Interferes with muscle function and medication effectiveness

Dietary Modifications for Easier Eating

Beyond avoiding specific foods, adapting how you eat can be beneficial for managing dysphagia.

• Modify food consistency: Choose softer foods and moisten dry ones with gravy, sauce, or yogurt. Cooking foods to a soft consistency is crucial for easier swallowing.
• Eat smaller, more frequent meals: This can help manage energy levels and prevent mealtime fatigue.
• Time meals with medication: Plan your meals for when your medication is most effective. For some, eating about an hour after taking anticholinesterase medication works well.
• Sit upright: Always maintain an upright, seated position while eating and drinking to reduce the risk of choking.

The Importance of Monitoring and Professional Guidance

Working with a registered dietitian or a speech-language pathologist can provide tailored advice for your specific needs, especially if you have significant chewing or swallowing difficulties. They can help you identify triggers, manage medication side effects through diet, and ensure you maintain adequate nutrition. Regularly tracking your food intake and how it affects your symptoms can also help pinpoint individual triggers.

Conclusion

While there is no one-size-fits-all diet for myasthenia gravis, avoiding certain foods can play a significant role in symptom management. Minimizing processed foods, sugar, salt, and alcohol, along with choosing appropriate food textures, can help reduce fatigue, prevent swallowing complications, and mitigate medication side effects. It is also crucial to avoid magnesium supplements and consult with healthcare professionals to ensure your dietary choices are safe and effective for your individual condition. By prioritizing nutrient-dense, easy-to-swallow options, you can better support your health and overall quality of life with myasthenia gravis.
