Most of the dizziness in liver cancer is caused by disease progression, and it may also be caused by the patient’s own basic diseases such as high blood pressure and cerebral infarction. 1. Liver cancer patients usually have dizziness symptoms because liver cancer is a consumptive disease, which can easily cause wasting, malnutrition, severe anemia and so on, leading to dizziness symptoms. When liver function decreases or brain metastasis occurs, dizziness symptoms may appear, accompanied by abdominal distension, nausea, headache and other symptoms. 2. Liver cancer patients with hypertension, cerebral infarction and other underlying diseases may also cause dizziness symptoms. This needs to be diagnosed by specialists, differentiated from liver cancer and treated. Liver cancer patients with dizziness symptoms should go to hospital for relevant examination and active treatment.
