The causes signs and dangers of hypertension

The cranium and its constituents blood, CSF, and brain tissue create a state of volume equilibrium, such that any increase in volume of one of the cranial constituents must be compensated by a decrease in volume of another. These buffers respond to increases in volume of the remaining intracranial constituents. For example, an increase in lesion volume e. One of the most damaging aspects of brain trauma and other conditions, directly correlated with poor outcome, is an elevated intracranial pressure.

Imaging[ edit ] Ultrasound is routinely used in the evaluation of cirrhosis. It may show a small and nodular liver in advanced cirrhosis along with increased echogenicity with irregular appearing areas.

Other liver findings suggestive of cirrhosis in imaging are an enlarged caudate lobewidening of the fissures and enlargement of the spleen.

Ultrasound may also screen for hepatocellular carcinoma, portal hypertension, and Budd-Chiari syndrome by assessing flow in the hepatic vein.

Cirrhosis is diagnosed with a variety of elastography techniques. Because a cirrhotic liver is generally stiffer than a healthy one, imaging the liver's stiffness can give diagnostic information about the location and severity of cirrhosis. Techniques used include transient elastographyacoustic radiation force impulse imagingsupersonic shear imaging and magnetic resonance elastography.

Compared to a biopsy, elastography can sample a much larger area and is painless. It shows a reasonable correlation with the severity of cirrhosis. Liver cirrhosis with ascites Liver cirrhosis as seen on a CT of the abdomen in transverse orientation caudate lobe hypertrophy in ultrasound due to cirrhosis Hepatofugal flow in portal vein in ultrasound Endoscopy[ edit ] Gastroscopy endoscopic examination of the esophagus, stomach, and duodenum is performed in patients with established cirrhosis to exclude the possibility of esophageal varices.

If these are found, prophylactic local therapy may be applied sclerotherapy or banding and beta blocker treatment may be commenced. Rarely are diseases of the bile ducts, such as primary sclerosing cholangitiscauses of cirrhosis.

Pathology[ edit ] Cirrhosis leading to hepatocellular carcinoma autopsy specimen Macroscopically, the liver is initially enlarged, but with the progression of the disease, it becomes smaller. Its surface is irregular, the consistency is firm, and the color is often yellow if associated with steatosis.

Depending on the size of the nodules, there are three macroscopic types: Mixed cirrhosis consists of nodules of different sizes. However, cirrhosis is defined by its pathological features on microscopy: The pattern of fibrosis seen can depend on the underlying insult that led to cirrhosis.

Fibrosis can also proliferate even if the underlying process that caused it has resolved or ceased. The fibrosis in cirrhosis can lead to destruction of other normal tissues in the liver: For example, in chronic hepatitis Bthere is infiltration of the liver parenchyma with lymphocytes.

This scoring system uses bilirubinalbuminINRthe presence and severity of ascitesand encephalopathy to classify patients into class A, B, or C. Class A has a favourable prognosis, while class C is at high risk of death.

Alcohol poisoning occurs when someone consumes a toxic level of alcohol, usually in a short time. Symptoms are much, much more severe than those of merely being drunk. Symptoms include abnormal. High blood pressure is a condition with serious health consequences that affects up to 80 million American adults. When detected and treated early, however, it can reduce the risk of heart attack, stroke, and kidney disease. High Blood Pressure During Childhood and Adolescence Using the recent American Academy of Pediatrics Clinical Practice Guideline, a new CDC study shows that many more youth are now considered to have hypertension.

This system was devised in by Child and Turcotte, and modified in by Pugh and others. The hepatic venous pressure gradient, difference in venous pressure between afferent and efferent blood to the liver also determines the severity of cirrhosis, although it is hard to measure. Research has suggested that coffee consumption appears to help protect against cirrhosis.

A healthy diet is encouraged, as cirrhosis may be an energy-consuming process.

High blood pressure (hypertension) - Symptoms and causes - Mayo Clinic

Close follow-up is often necessary. Antibiotics are prescribed for infections, and various medications can help with itching. Laxatives, such as lactulosedecrease the risk of constipation; their role in preventing encephalopathy is limited.

Alcoholic cirrhosis caused by alcohol abuse is treated by abstaining from alcohol. Treatment for hepatitis-related cirrhosis involves medications used to treat the different types of hepatitis, such as interferon for viral hepatitis and corticosteroids for autoimmune hepatitis.High blood pressure is a condition with serious health consequences that affects up to 80 million American adults.

When detected and treated early, however, it can reduce the risk of heart attack, stroke, and kidney disease. Symptoms. Most people with high blood pressure have no signs or symptoms, even if blood pressure readings reach dangerously high levels.

A few people with high blood pressure may have headaches, shortness of breath or nosebleeds, but these signs and symptoms aren't specific and usually don't occur until high blood pressure has reached .
