What are the precursors of myasthenia

Myasthenia is an autoimmune disease, mainly caused by problems at the neuromuscular junction in skeletal muscles, which is clinically characterized by continuous activity of voluntary muscles, contraction, weakness and fatigue, and regaining strength after a short period of rest. Myasthenia is that there is an antibody in the body that should not be there, which destroys the acetylcholicin receptor on the muscle, and the muscle cannot accept the command of the nerve and act.

The most important feature of this disease is that the muscles are abnormally tired and weak, and the symptoms are significantly improved after rest, and there is no severe muscle atrophy and electrical degeneration. All muscles that can appear throughout the body: oh.

1.ptosis: manifested by monocular ptosis or alternating ptosis; 2.

Ocular motility disorders: patients have unclear vision and diplopia; 3.proximal limb weakness, weakness in chewing, choking on water, difficulty swallowing; 4.

Respiratory muscle weakness: the patient has difficulty breathing.

The most common presenting symptom of myasthenia gravis is ptosis.

and binocular diplopia. Patients may also have muscle weakness in the extraocular muscles, laryngeal muscles, or extremities alone at the beginning of the disease. This is followed by the gradual involvement of more skeletal muscles, from the face and limbs to the respiratory muscles, affecting normal life and even life-threatening.

When the upper limbs are affected, the arms cannot be lifted, and it is difficult to comb the hair, brush the teeth, and dress; When the lower limbs are affected, the legs are weak when going upstairs, and the lower limbs are fatigued when lifting up, which gradually develops into difficulty climbing the stairs or getting on the bus.

1. Weakness in chewing.

The most common symptom of patients with myasthenia gravis in the early stage is chewing weakness, which is because the muscles of the face have lost their normal function, so that the strength of chewing has decreased, although there is no problem with the teeth or mouth, but there is no muscle to support the force when biting. Patients in this condition also need to be highly noted, as it is most likely caused by severe muscle weakness and needs to be done in a timely manner**.

2. Double vision. This is also a symptom of myasthenia gravis that tends to occur in the early stages, when the patient looks at one thing, it is easy to see things as two, and in this case, it may be caused by myasthenia gravis. This symptom often occurs in younger children, and some children may also have significant torticollis symptoms due to poor descriptions of symptoms.

3. General weakness.

Patients with myasthenia gravis do not have much change from the appearance, but the patient's muscles have obvious lesions, muscle atrophy or loss of muscle function from time to time, which often leads to patients finding that the whole body is often weak, and the normal life is significantly affected. Usually, the arm is weak, and even when grasping something, the finger strength cannot be effectively guaranteed, and the thing will fall off at this time. In the early stages, the most typical symptom is finding that you are getting tired more and more easily at work.

4. Drooping eyelids.

Drootic eyelids, that is, the eyelids begin to shrug downward, is the first symptom of most patients with myasthenia gravis, because this symptom can occur in patients of any age, so when the eyelid drooping problem is found, it is necessary to go to the hospital in time**. If myasthenia gravis progresses to an advanced stage, the problem of drooping eyelids will continue to appear, and the symptoms of drooping on both sides will appear, and many patients will have their ability to see affected by drooping eyelids.

5. Facial muscle weakness.

Patients with myasthenia gravis often have symptoms of facial muscle weakness, often that is, they cannot close their eyes normally during sleep, which is caused by eyelid weakness, and it is also found that these patients cannot control their facial expressions in daily life, and sometimes they cannot smile normally, which will make the smile unnatural.

6. Difficulty breathing.

Dyspnea is the most severe symptom that patients with myasthenia gravis may have, and patients often experience suffocation for a short period of time due to the manifestation of this symptom, and some patients can easily suffocate to death if they have respiratory muscle weakness during sleep. In addition, when there is a lung infection or corresponding respiratory problems, the sputum in the lungs cannot be coughed up normally, which can easily affect the life safety of the patient.

How is muscle weakness caused and what are the main symptoms?

The main symptoms of muscle weakness are muscle fatigue and weakness, and in severe cases, muscle atrophy. The symptoms of muscle weakness fluctuate to a certain extent, most patients are mild in the morning and heavy in the afternoon, and the symptoms are significantly aggravated after labor or strenuous activities, and the symptoms can be relieved after rest. Some patients have ptosis of the upper eyelids, which may lead to respiratory failure and even life-threatening if the disease progresses.

It is recommended that you **, soon**.
