Hepatitis is a disease that affects liver function, and its symptoms may vary depending on the type of infection, stage of the disease, and individual constitution. Viral hepatitis (such as hepatitis A, B, and C) can present very differently from other types (such as alcoholic or autoimmune hepatitis). Initial symptoms are often mistaken for general fatigue or gastrointestinal discomfort, but if not diagnosed in a timely manner, it may lead to long-term liver damage or even failure.
The severity of symptoms is directly related to the extent of liver damage, but it is worth noting that some patients may be completely asymptomatic during the acute phase. Patients with chronic hepatitis may experience long-term mild symptoms, which may gradually worsen or only be noticed when complications arise. Early recognition of symptoms and professional medical evaluation are key to preventing permanent liver damage.
The early symptoms of hepatitis are usually mild and nonspecific, often misinterpreted as general fatigue or indigestion. Common early signs include persistent fatigue, muscle and joint aches, and mild discomfort in the upper abdomen. These symptoms may last for several weeks, but patients may not immediately associate them with liver issues.
In the early stages of acute viral hepatitis infection, some patients may exhibit flu-like symptoms such as fever, chills, and headaches. These signs may appear within weeks of infection, but approximately 30-50% of hepatitis A patients may not show obvious symptoms during the acute phase. Early symptoms of hepatitis B and C may be even more subtle, but liver damage continues to progress.
When liver function is compromised beyond a certain extent, typical symptoms will significantly increase. Jaundice is the most characteristic manifestation, presenting as yellowing of the skin and the whites of the eyes, dark urine resembling tea, and possibly accompanied by pale stools. These changes are direct evidence that the liver is unable to metabolize bilirubin normally.
In chronic hepatitis patients, long-term fatigue and difficulty concentrating may become major concerns. These symptoms are often misinterpreted as stress or lack of sleep, leading to delayed diagnosis. Additionally, some patients may experience coagulation abnormalities, such as bleeding gums or increased bruising, related to the liver's impaired ability to produce clotting factors.
Symptoms of acute hepatitis may suddenly appear within weeks of infection, while chronic hepatitis patients often experience a gradual worsening of symptoms. During the acute phase, jaundice, severe vomiting, and abdominal pain may rapidly worsen within days, requiring immediate medical attention. Chronic hepatitis may go through years of asymptomatic periods, followed by the gradual emergence of symptoms related to cirrhosis, such as ascites and hepatic encephalopathy.
When liver damage progresses to the stage of cirrhosis, symptoms will shift to more severe systemic effects. Possible complications include:
Among patients with hepatitis C, approximately 15-30% of acute infections may progress to chronic, during which intermittent symptoms may recur, including unexplained fever and joint pain, related to the long-term struggle between the immune system and the virus.
If any of the following symptoms occur, immediate medical assistance should be sought:
Even if symptoms seem mild, if the following conditions apply, a check-up should also be conducted:
Chronic hepatitis patients who develop new symptoms (such as ankle swelling or changes in consciousness) on top of their existing symptoms should consider this an important warning sign of disease worsening, requiring immediate liver function assessment and treatment adjustment.
Chronic hepatitis patients should avoid high-fat, high-sugar, and processed foods to reduce the metabolic burden on the liver. It is recommended to increase high-fiber foods (such as whole grains and vegetables) and fruits rich in vitamin C, while controlling salt intake to prevent edema. Alcohol should be completely avoided, as it exacerbates liver damage.
When jaundice symptoms appear, under what circumstances should immediate medical attention be sought?When the skin or whites of the eyes turn yellow (jaundice) accompanied by severe fatigue, tea-colored urine, or pale stools, it indicates that liver function may be deteriorating, requiring immediate medical examination. If complications such as ascites or altered consciousness occur, this is even more urgent.
What are the differences in transmission routes between hepatitis B and hepatitis C?Hepatitis B is primarily transmitted through blood, sexual contact, or vertical transmission from mother to child, while hepatitis C is mainly transmitted through blood contact, such as sharing needles or medical instruments. Neither is transmitted through casual contact (such as sharing meals), but precautions should be taken to avoid contact with personal blood and bodily fluids.
What are common side effects for hepatitis patients receiving interferon treatment?Interferon may cause flu-like symptoms (fever, chills), decreased white blood cell count, and mood swings. Some patients may experience dizziness or fatigue, and regular blood tests are required to monitor blood indices during treatment, along with communication with the physician regarding the severity of side effects to adjust dosages.
Which vaccinations can effectively prevent hepatitis virus infections?The hepatitis A vaccine provides long-lasting immunity, while the hepatitis B vaccine requires three doses to produce sufficient antibodies. Currently, there is no vaccine for hepatitis C, so prevention of infection should be through avoiding blood contact and practicing safe behaviors.
