Hepatitis B and hypertension are two diseases that, when suffered at the same time, can cause cirrhosis, primary liver cancer, and related cardiovascular and cerebrovascular complications caused by hypertension. 1. Cirrhosis: viral hepatitis can cause cirrhosis, which is manifested by chronic inflammation of liver, diffuse fibrosis, pseudo lobe and regenerative nodules. The decompensated stage will cause hepatic decompensation, portal hypertension, gastrointestinal bleeding, hepatic encephalopathy and so on. Generally, diuresis, transjugular intrahepatic portosystemic shunt, and liver transplantation in the terminal stage are carried out as treatment pathways. 2. Primary liver cancer: viral liver cancer is the main cause of liver cancer in China. When malignant tumor appears in hepatocytes or intrahepatic bile duct epithelial cells, hepatomegaly, jaundice, hepatic encephalopathy, upper gastrointestinal bleeding, rupture and bleeding of hepatocellular carcinoma nodules, secondary infection and other manifestations can occur. Surgery, local radiofrequency ablation, hepatic artery embolization, liver transplantation and other therapeutic means are usually needed. 3. Hypertension-related complications: it may cause cerebrovascular disease, including cerebral hemorrhage, cerebral thrombosis, lacunar cerebral infarction, transient ischemic attack and so on. It may also complicate heart failure, coronary heart disease, chronic renal failure, aortic coarctation and other diseases. Treatment of the primary disease is usually required, with lifelong use of antihypertensive drugs such as hydrochlorothiazide diuretics and angiotensin-converting enzyme inhibitors such as captopril. If you have hepatitis B combined with hypertension, you need to seek medical treatment as soon as possible, do not self-medicate to avoid delays.
