Cerebral embolism is a type of cerebral infarction. It is a condition caused by the dislodgment of emboli, leading to the interruption of blood flow in the brain and resulting in the necrosis of brain tissue and cerebral infarction. There are no special dietary requirements for this condition, but it is generally advisable to follow a low-salt, low-fat diet, as high levels of salt or fats can be risk factors for cerebral infarction. Additionally, cerebral embolism can also be caused by atrial fibrillation. Patients with atrial fibrillation must monitor their coagulation function carefully and pay attention to cardiac issues. Regarding the diet, it should be low in salt and fat, and if the patient does not have diabetes, there is no need to pay special attention to blood sugar levels. However, if diabetes is present, diabetic dietary guidelines must be followed.
