Myasthenia gravis is a common disease in neurology, so when visiting the hospital, it is definitely necessary to see a neurologist. Neurologists have certain experience in diagnosing and treating this disease. This disease is classified as a neuromuscular junction disorder, mainly caused by the production of antibodies against acetylcholine receptors in the body. This leads to the nerve impulses not being effectively transmitted to the muscles, resulting in clinical manifestations. Patients' symptoms include improvement in the morning and worsening in the evening, fluctuating symptoms, and may present with drooping eyelids, double vision, general weakness, and some patients may also experience difficulty swallowing and speech disorders.
