Hepatitis C is a liver disease brought on by the hepatitis C virus: the virus can bring about both acute and chronic hepatitis, going in seriousness from a mild illness lasting a few weeks to a serious, lifetime illness.
What is Hepatitis C
The hepatitis C virus is a bloodborne virus and the most common modes of infection are through exposure to small quantities of blood. This may happen through injection drug use, unsafe injection practices, unsafe health care, and the transfusion of unscreened blood and blood products.
Globally, an estimated 71 million people have chronic hepatitis C infection.
A critical number of those who are chronically affected will develop cirrhosis or liver cancer.
Approximately 399 000 people die yearly from hepatitis C, primarily from cirrhosis and hepatocellular carcinoma.
Antiviral medications can cure more than 95% of persons with hepatitis C infection, thereby reducing the hazard of death from liver cancer and cirrhosis, but accessibility to diagnosis and treatment is low.
There is at present no vaccine for hepatitis C; however research in this area is continuing.
Acute vs Chronic Hepatitis C
Hepatitis C virus (HCV) causes both acute and chronic infection. Acute HCV infection is usually asymptomatic, and is only very seldom (if ever) associated with life-threatening disease. About 15-- 45% of infected persons spontaneously clear the virus within 6 months of infection without any treatment.
The remaining 60-- 80% of persons will develop chronic HCV infection. Of those with chronic HCV infection, the risk of cirrhosis of the liver is between 15-- 30% within 20 years.
Your liver is your major internal organ and your body's workhorse. Among its many jobs are converting food into fuel, processing fat from your blood, clearing harmful toxins, and making proteins that help your blood clot. Yet this tireless, supersized organ is susceptible to an often hard-to-diagnose and dangerous condition called nonalcoholic fatty liver disease, or NAFLD.
Liver disease - Fatty Liver
NAFLD is defined as the existence of fat in more than 5% of liver cells. It is the most commonplace liver disease and affects up to 25% of American adults, 60% of whom are men.
The disease raises your risk of heart disease and left untreated, NAFLD also can lead to an inflamed liver, a condition called nonalcoholic steatohepatitis (NASH).
As many as 40% of people with NAFLD develop NASH. NASH can result in scarring of the liver; severe scarring, called cirrhosis, increases your risk of liver cancer.
A growing problem.
Drinking too much alcohol can cause fat buildup in the liver, NAFLD affects people who consume little or no alcohol.
Instead, the main offender is excess weight-- which causes extra fat to get stored in the liver-- and is associated with dyslipidemia (abnormally high LDL cholesterol levels, low HDL levels, or both), high blood pressure, and diabetes.
Fatty Liver & Obesity
As the number of overweight people has increased, so too has the prevalence of NAFLD. "Much of this can be attributed to a regular diet of more highly processed foods and significant amounts of carbohydrates, as well as more sedentary lifestyles," says Dr. Kathleen Corey, director of the Fatty Liver Disease Clinic at Harvard-affiliated Massachusetts General Hospital. here She adds that some people with fatty livers have none of these risk factors, which suggests that genes can play an important role.
Creating healthy eating habits isn't as complicated or as limiting as many individuals imagine. The important steps are to eat mostly foods derived from plants-- vegetables, fruits, whole grains and legumes (beans, peas, lentils)-- and limit highly processed foods.
