Patients with myasthenia gravis are prone to catching colds because myasthenia gravis is an immune system disease, and patients with this condition generally have lower immunity, making them more susceptible to a decrease in resistance and cold symptoms. If a person with myasthenia gravis catches a cold, it is important to keep warm, drink plenty of water, and monitor body temperature to avoid high fever. It is also important to give antiviral and antipyretic medications for treatment. Regularly eating fresh vegetables and fruits, and taking a significant amount of vitamins can help boost the immune system. Nutritional balance is important, as is ensuring adequate sleep, eliminating anxiety and depression, avoiding excessive emotional fluctuations, and consuming high-protein, high-nutrient, and high-vitamin foods.
