How long it takes to recover swallowing function after cerebral infarction varies from person to person and depends on the severity of the lesion. For patients with mild cerebral infarction death, some of them can be clinically cured within two weeks if they can be treated timely and correctly, and most patients often recover gradually after two weeks to within six months. If patients still have swallowing dysfunction after one year, it is called the posterior phase, and patients who enter the posterior phase have poorer treatment outcomes. Swallowing dysfunction caused by cerebral infarction death is mainly seen in patients with large cerebral infarction death and brainstem infarction, including dysphagia and choking on water. If patients have swallowing dysfunction in the short term and cannot recover, they should be given a gastric tube as early as possible, retaining the gastric tube and nasal feeding diet to prevent patients from choking by mistake and prevent causing aspiration pneumonia to replenish essential nutrients, etc.
