Myasthenia gravis affecting respiration can be cured because myasthenia gravis can improve after treatments such as oral medication or plasmapheresis. Another possibility is myasthenia gravis concurrent with a myasthenic crisis, which has various forms, causing respiratory difficulties. At this point, symptomatic treatment is required, including the use of ventilators, intubation, and in severe cases, a tracheotomy. After the critical period on the ventilator passes, respiratory function can improve or the myasthenia can ameliorate.

Does myasthenia gravis require hospitalization?

Myasthenia Gravis is a type of neuroimmune disease within the field of neurology which fundamentally stems from issues with the patient's own immune function. Whether hospitalization is necessary depends critically on the severity of the disease. If Myasthenia Gravis manifests only as ocular symptoms, such as ptosis and double vision, hospitalization is generally not necessary. It is important to take certain medications, primarily cholinesterase inhibitors and corticosteroids, but regular outpatient follow-ups are essential. However, if Myasthenia Gravis is generalized, with noticeable whole-body weakness, particularly if accompanied by swallowing difficulties and coughing while drinking, hospitalization is required. If a myasthenic crisis occurs, presenting with respiratory muscle weakness and breathing difficulties, hospitalization is certainly needed, and admission to the ICU might be necessary.

Myasthenia Gravis Test Items

Myasthenia gravis is a common neurological disease, primarily an autoimmune disorder. It typically results in symptoms that are worse in the evening and fluctuate throughout the day, mainly manifesting as limb weakness, double vision, swallowing difficulties, and speech impairments. In severe cases, it can even affect respiration, leading to weakness of the respiratory muscles and necessitating the assistance of a ventilator. The key examinations for myasthenia gravis include: Firstly, a chest CT scan. Many patients with myasthenia gravis have thymic hyperplasia or thymomas, making this scan crucial. Secondly, repetitive nerve stimulation electromyography. This test can detect amplitude decrement in response to stimulation, which is significant for diagnosing the disease. Thirdly, testing for specific antibodies related to myasthenia gravis, such as acetylcholine receptor antibodies. The presence of these antibodies is very important for diagnosis. Additionally, other tests such as erythrocyte sedimentation rate and thyroid function tests are also conducted.

What should I do if myasthenia gravis is accompanied by a fever?

Patients with myasthenia gravis are most afraid of developing a fever, as a fever may indicate an infection, especially a bacterial infection. If a bacterial infection occurs, it can easily trigger a myasthenic crisis. The patient may experience weakness in breathing and even respiratory failure, which can be life-threatening. Therefore, it is essential to address the situation promptly. The recommended approach when a fever occurs is as follows: First, quickly determine the cause of the fever, complete routine blood tests, calcitonin, and other relevant assays to confirm if it is caused by a bacterial infection. Second, symptomatically manage the fever, possibly using antipyretic medications. Third, if it is a bacterial infection, it is crucial to promptly administer a significant amount of effective antibiotics to treat it. Controlling the bacterial infection can prevent the progression of myasthenia gravis to a more severe state. (Note: Medication should be used under the guidance of a doctor.)

Does myasthenia gravis hurt?

Myasthenia gravis does not cause pain. Initially, patients with myasthenia gravis may feel discomfort such as soreness or swelling in the eyes or limbs, blurred vision, or fatigue. As the condition progresses, skeletal muscles become noticeably fatigued and weak. A significant characteristic is muscle weakness, which worsens after exertion in the afternoon or evening and improves after rest in the morning, known as "morning better, evening worse." Patients with myasthenia gravis can experience involvement of skeletal muscles throughout the body, manifesting as drooping eyelids, blurred vision, double vision, strabismus, restricted eye movements, bland facial expressions, a "forced smile" appearance, speech impairments resembling a thick tongue often accompanied by a nasal sound. Additionally, they may have chewing difficulties, coughing or choking when drinking, swallowing difficulties, trouble raising the head, weak shoulder shrugging, difficulty lifting arms, combing hair, climbing stairs, squatting, and getting into vehicles, primarily due to muscle weakness, which does not lead to pain.

Will severe myasthenia gravis swallowing difficulties improve?

Myasthenia gravis and difficulty swallowing generally improve with medication treatment. Myasthenia gravis is a neuromuscular disease that typically presents with worsened muscle weakness and swallowing difficulties during fatigue. This condition requires targeted pharmacological treatment and further repetitive stimulation, which can involve specific medications and steroids. Swallowing difficulties associated with myasthenia gravis are typical of generalized myasthenia gravis, necessitating active pharmaceutical treatment, which usually has good outcomes. Avoid overworking, staying up too late, smoking, and excessive drinking. It is important to rest sufficiently, ensure ample sleep, eat fresh vegetables and fruits, and consume high-protein, nutritious foods.
