Patients with myasthenia gravis must use ornidazole with caution and under the guidance of a doctor because the side effects of ornidazole may exacerbate myasthenia gravis. However, ornidazole is not relatively or absolutely contraindicated for patients with myasthenia gravis. Generally, the patient's side effects are observed, and if myasthenia gravis is aggravated, the use of ornidazole is recommended to be cautious or prohibited. Ornidazole can cause neurological reactions, including headache, fatigue, dizziness, trembling, limb numbness and weakness, convulsions, mental confusion, epileptic seizures, ataxia, and consciousness disturbances, and may cause peripheral nerve damage.

Myasthenia gravis belongs to which department?

Myasthenia gravis is an autoimmune disease of the nervous system, primarily affecting the neuromuscular junction where synaptic function is significantly impaired. This disease falls under the purview of neurology, and most neurologists are quite familiar with myasthenia gravis, considering it a common and frequently occurring neurological condition. Patients with myasthenia gravis typically exhibit symptoms such as drooping eyelids, double vision, and general fatigue. They experience a pathological tiredness, feeling extremely exhausted after minor activities, although rest can alleviate symptoms. These symptoms are also commonly associated with the nervous system, so it is appropriate to consult the neurology department. Treatment for patients with myasthenia gravis may involve administering immunoglobulins or corticosteroids, depending on the situation, while also taking precautions to prevent potential complications.

What is good to eat for myasthenia gravis?

Myasthenia gravis is an autoimmune disease of the nervous system that primarily affects the neuromuscular junction, leading to muscle weakness and post-exertional fatigue. Some patients may also experience clinical symptoms such as ptosis and diplopia. The main treatments include corticosteroids and immunosuppressants. Patients with myasthenia gravis should pay attention to their diet: First, consume plenty of fresh vegetables and fruits, which are rich in vitamins that can provide sufficient immunity to prevent certain complications. Second, eat foods high in B vitamins, such as animal liver, lean meat, and whole grains, which are beneficial for patients. Third, patients should also consume high-quality proteins, which provide ample nutrition and increase resistance, including items such as milk, beef, and fish.

Early symptoms of myasthenia gravis

Myasthenia gravis is an autoimmune disease of the nervous system that primarily affects the acetylcholine receptors on the postsynaptic membrane, causing muscle fatigue in patients. This can lead to general weakness throughout the body, double vision, and even progressive paralysis of the respiratory muscles, requiring active breathing assistance in severe cases. The early symptoms of myasthenia gravis mainly include: First, patients tend to fatigue easily, such as after exercise or labor, with a rapid decline in physical strength that only recovers after resting. Second, there may be ptosis, with patients unable to comfortably open their eyes, although this symptom can improve after resting or sleeping. As myasthenia gravis progresses into its later stages, there is a marked increase in overall weakness, necessitating treatment in a neurology department.

Early symptoms of myasthenia gravis

Myasthenia gravis is a disease of the neuromuscular junction and also an autoimmune disease, caused by a dysfunction in the patient's immune system. Early symptoms of myasthenia gravis may include mild general fatigue, which can be relieved by rest, and may not be particularly concerning to the individual. Some patients may initially exhibit slight ptosis and occasional double vision as clinical symptoms, which they might not take very seriously either. As the disease progresses, the symptoms become more severe, such as noticeable ptosis, double vision, slurred speech, difficulty swallowing, and even potential weakness of the respiratory muscles, leading to respiratory failure.

Myasthenia Gravis Clinical Manifestations

The clinical manifestations of myasthenia gravis include fluctuating weakness of specific striated muscles that is fatigue-prone. Symptoms are generally milder in the morning and worsen by night, increasing after sustained activity and alleviating after rest. Additionally, some patients may experience ocular muscle weakness, presenting with ptosis and diplopia, which could be among the earliest symptoms. Eye movement disorders may occur, preventing the eyes from looking to one side, and pupil abnormalities may be present. Facial muscle weakness can lead to cheek puffing and air leakage, inability to close the eyes, or asymmetry of the mouth, resembling a forced smile. There may also be weakness in the masticatory muscles, leading to difficulties in chewing and swallowing, potential speech impairments, and coughing when drinking water. Neck muscle weakness may manifest as difficulty in lifting the head. Muscle weakness can affect various limbs, primarily proximally, and respiratory muscle weakness can lead to breathing difficulties and dryness.
