肝炎的症状有哪些
最佳答案：
Hepatitis means inflammation of the liver. Drugs,toxins,heavy use of alcohol,reduced blood supply to the liver,and microorganisms including viruses may cause it. However,signs and symptoms of hepatitis from any virus are similar and the specific cause is often undistinguishable without blood tests. Sometimes patients have no symptoms. When patients do experience symptoms,these may include jaundice (yellowing of the eyes and skin),fatigue,lethargy,nausea,vomiting,loss of appetite,abdominal pain,and fever. In severe cases,patients may start noticing swelling of feet,abdomen,or confusion and drowsiness. If any combination of these symptoms occurs,medical care should be sought immediately.
2. How does it occur? Is it contagious?
Most viral hepatitis occurs from human-to-human transmission,though animal-to-human transmission may also occur. Different viruses may be transmitted either from contaminated water and food; bodily secretions like blood,semen,and saliva (e.g.,herpesviruses); or droplets when people cough or sneeze (influenza). The mechanism of transmission and its contagiousness is specific to each virus.
3. How are these infections treated?
Hepatitis caused by viruses is usually treated symptomatically,meaning treating the symptoms of liver inflammation rather than the virus itself. However,some viruses may have a specific antiviral that can be used to eradicate it and prevent progression of the disease.
4. How do I know if I am getting better?
Recovery after viral hepatitis typically starts with gradual resolution of nausea,vomiting,abdominal pain,and return of appetite and energy. The jaundice is usually the last to resolve.","department":"
