Hepatitis C is a liver disease brought on by the hepatitis C virus: the virus can inflict both chronic and acute hepatitis, running in seriousness from a mild illness lasting a few weeks to a serious, constant 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.
Across the world, an estimated 71 million people have chronic hepatitis C infection.
A great number of those who are chronically affected will develop cirrhosis or liver cancer.
Approximately 399 000 people die each year from hepatitis C, mostly from cirrhosis and hepatocellular carcinoma.
Antiviral drugs can cure in excess of 95% of persons with hepatitis C infection, thus reducing the threat of death from liver cancer and cirrhosis, but availability to diagnosis and treatment is low.
There is currently no vaccine for hepatitis C; however research in this field is continuing.
Acute vs Chronic Hepatitis C
Hepatitis C virus (HCV) causes both chronic and acute infection. Acute HCV infection is generally asymptomatic, and is only very hardly (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 cultivate 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 largest internal organ and your body's workhorse. Among its many jobs are converting food into fuel, read more processing fat from your blood, clearing harmful toxins, and making proteins that help your blood clot. Yet this hard-working, supersized organ is vulnerable 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 presence of fat in more than 5% of liver cells. It is the most prevalent liver disease and affects up to 25% of American adults, 60% of whom are men.
The disease increases 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 bring on scarring of the liver; severe scarring, called cirrhosis, increases your risk of liver cancer.
A growing problem.
Consuming too much alcohol can cause fat buildup in the liver, NAFLD affects people who consume little or no alcohol.
Instead, the main offender is surplus weight-- which causes extra fat to get stored in the liver-- and is related to 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 habitual diet of more processed foods and high amounts of carbohydrates, in conjunction with more sedentary lifestyles," says Dr. Kathleen Corey, director of the Fatty Liver Disease Clinic at Harvard-affiliated Massachusetts General Hospital. She adds that some people with fatty livers have none of these risk factors, which suggests that genes can play an important role.
Acquiring healthy eating habits isn't as complex or as limiting as many people imagine. The necessary steps are to eat mostly foods derived from plants-- vegetables, fruits, whole grains and legumes (beans, peas, lentils)-- and limit highly processed foods.
