Myasthenia gravis is considered a neurological disease, so if myasthenia gravis is suspected, it is advisable to consult a neurologist. Neurologists are quite familiar with myasthenia gravis, especially those who specialize in its research. They are particularly knowledgeable about diagnosing and treating this disease. Myasthenia gravis is an autoimmune disease of the nervous system that primarily affects the neuromuscular junction, causing muscle weakness in the body. The symptoms typically worsen towards the evening and include pathological fatigue. Muscle weakness usually improves after rest. Clinical manifestations also include ptosis, double vision, difficulty swallowing, and coughing while drinking. Neurologists may prescribe various diagnostic tests such as electromyography, chest CT scans, and tests for acetylcholine receptor antibodies.

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.

Is it dangerous to have a fever with myasthenia gravis?

Myasthenia gravis is a disease of the neuromuscular junction, essentially an autoimmune inflammatory response that causes generalized weakness and fatigue of the skeletal muscles, with symptoms that are less severe in the morning and worsen by the evening, and fluctuate over time. The weakness can be alleviated by rest. When patients with myasthenia gravis develop a fever, it is generally considered to be caused by an infection, perhaps a viral infection such as an upper respiratory tract infection, which can also induce fever. In such cases, the main treatment involves drinking plenty of water and consuming fresh vegetables and fruits. If necessary, some antiviral medications and antipyretics may be administered. If the fever is due to a bacterial infection, symptomatic treatment should be accompanied by the appropriate antibiotics. However, the choice of antibiotics must be made with caution. Patients with myasthenia gravis should not use aminoglycosides or fluoroquinolones, as these could exacerbate their condition. Penicillins or cephalosporins may be used instead. (Please consult a professional physician for specific medication guidance.)

What is myasthenia gravis?

Myasthenia gravis is a group of neuromuscular junction disorders and is also an autoimmune disease of the nervous system. It primarily involves the production of certain antibodies in the body that attack the acetylcholine receptors on the postsynaptic membrane of the neuromuscular junction. This results in the inability of nerve impulses to be effectively transmitted to the muscles, causing the muscles to lose neural control, leading to weakness of the limbs. This weakness is typically more pronounced in the evening than in the morning, with symptoms being lighter upon waking and worsening in the afternoon. As the disease is caused by an autoimmune response, a major focus of treatment is to suppress this abnormal immune reaction, primarily through the administration of corticosteroids. Additionally, many patients with myasthenia gravis also exhibit thymus abnormalities, necessitating thorough CT examinations of the thymus.

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.

How to alleviate myasthenia gravis?

Myasthenia gravis is a disease of the department of neurology and its incidence is not low, it is also relatively common clinically. The treatment of myasthenia gravis mainly includes the following points: First, if patients with myasthenia gravis also have a thymoma, it is recommended to surgically remove the thymoma as soon as possible, which can significantly alleviate the symptoms of myasthenia gravis and reduce the amount of medication needed. Second, provide patients with some medication, mainly some drugs that suppress the immune response, including some corticosteroids. The use of corticosteroids is relatively complex, and must be gradually increased or decreased under the advice of a doctor. Do not stop taking them on your own. There are also some drugs that are cholinesterase inhibitors, which can increase the content of acetylcholine in the synaptic gap, alleviating the patient's symptoms. In addition, research has confirmed that some new immunosuppressive agents can also be used in the treatment of myasthenia gravis. In summary, the treatment of myasthenia gravis is a comprehensive subject and must be tailored according to the patient's condition.
