Myasthenia gravis falls under the category of neurological diseases, characterized as an immune disorder of the nervous system, primarily due to the presence of antibodies against acetylcholine receptors. This leads to impaired transmission of nerve impulses to muscles, resulting in various clinical symptoms. The treatment approaches for myasthenia gravis include the following. Firstly, the use of cholinesterase inhibitors is recommended. These medications increase acetylcholine levels and are effective in improving symptoms. Secondly, patients are treated with corticosteroids, typically starting with a low dose and gradually increasing to maintain for a period before reducing the dose again. Adjustments to medication should always be made under the guidance of a neurologist. Third, if the patient has a thymoma, surgical removal is advised.

Myasthenia gravis initial symptoms

Myasthenia gravis is characterized by fluctuating and fatigue-prone muscle weakness in certain specific striated muscles. Symptoms are generally milder in the morning and more severe in the evening, worsening with continued activity and alleviating after rest. The most common initial symptom is weakness of the external eye muscles, primarily presenting as asymmetrical ptosis (drooping of the upper eyelid) or narrowing of the eye slit, along with diplopia, which refers to seeing double images. These are the most frequent initial symptoms, seen in over 50% of patients with myasthenia gravis. Additionally, some patients may experience disturbances in eye movement, facial muscle weakness, air leakage when puffing cheeks, incomplete eyelid closure, shallower nasolabial folds, as well as difficulty swallowing, speech articulation issues, choking while drinking, and potentially severe respiratory weakness.

What should not be eaten in the case of myasthenia gravis?

Myasthenia gravis is an autoimmune disease of the nervous system, primarily due to dysfunction at the neuromuscular junction, leading to skeletal muscle fatigue. Symptoms include drooping eyelids, double vision, overall weakness, and even swallowing difficulties. Foods that should be avoided in myasthenia gravis mainly include certain medications, such as aminoglycoside antibiotics, which should not be taken orally by patients, as well as fluoroquinolone antibiotics. These antibiotics can exacerbate neuromuscular transmission disorders, potentially worsening the disease. Additionally, benzodiazepines, barbiturates, and some anti-arrhythmic drugs can also reduce muscle membrane excitability and should be avoided.

How is myasthenia gravis diagnosed?

Myasthenia gravis is essentially an immunoreactive disease in neurology, primarily caused by immune dysfunction in the body, leading to the production of autoantibodies. These antibodies attack the acetylcholine receptors on the postsynaptic membrane, resulting in corresponding clinical symptoms such as ptosis, diplopia, and general fatigue. The examination of myasthenia gravis mainly includes the following aspects: first, the completion of the Tensilon test, and if the test is positive, myasthenia gravis should be considered; second, the examination should include repetitive nerve stimulation electromyography, and if there is a significant decrement in wave amplitude, this disease should be considered; third, relevant blood tests should be conducted, mainly to check for acetylcholine receptor antibodies, as positive results for these antibodies are important in supporting this diagnosis.

Can people with myasthenia gravis soak their feet?

Soaking in hot water can promote blood circulation, dilate blood vessels, improve local blood circulation in the lower limbs, promote metabolism, prevent thrombosis, and prevent muscle atrophy. In the early stages of myasthenia gravis, patients often experience limb discomfort, numbness, pain, blurred vision, and fatigue. In work and daily life, it is common to experience tiredness, memory loss, slow responses, and reluctance to be active. Soaking the feet can promote blood circulation and can improve local blood flow, which has a certain beneficial effect on myasthenia gravis. As the disease progresses, there is obvious fatigue and weakness in the skeletal muscles, especially after fatigue in the afternoon and evening, which is reduced in the morning or after rest.

What are the side effects of taking steroid medication for myasthenia gravis?

The side effects of steroids in treating myasthenia gravis mainly include Cushing's syndrome characterized by specific facial and bodily features, weight gain, swelling in the lower legs, purple striae, tendency to bleed easily, poor wound healing, acne, and menstrual disorders. There could also be ischemic necrosis of the femoral or humeral heads, osteoporosis and fractures, primarily compressive vertebral fractures, as well as pathological fractures of the long bones, muscle weakness, muscle atrophy, and hypokalemia syndrome. Gastrointestinal irritation is common, primarily nausea and vomiting, as well as peptic ulcers or perforation, pancreatitis, and suppressed growth in children.
