# Symptoms and phases of chronic hepatitis B
Chronic hepatitis B progresses in phases that can differ depending on a person's viral load, age, sex, and immune system. This tab describes what happens in each stage of the disease and how it feels.
Phase 1: Immunotolerant phase (HBeAg-positive)
In this phase – usually early in the infection – the body produces what is called HBeAg (an antigen present in the blood). The virus multiplies strongly, but many people have few or no complaints.
**Symptoms in this phase: **
- Often no symptoms, despite high viral load
- Fatigue and general feeling of malaise
- Sometimes mild nausea or lack of appetite
- Possible yellowing of skin and eyes (jaundice) – usually mild and transient
- Slightly enlarged liver (not always palpable)
- With more acute inflammation: abdominal pain, headache, joint pain
**What this means for daily life: **
If you have no complaints, you probably feel normal. Many people don't even know they are infected until tested. If fatigue occurs, it can affect work and activities. Because there are no warning signs, regular check-ups by a doctor are important – feeling well does not mean there is nothing wrong.
**Figures about this phase: **
This phase can last months to tens of years; median duration is highly variable and depends strongly on age and immune response. Survival figures for this phase alone are not well distinguished from later stages; studies from 2024–2026 focus more on prognostic factors than on phase-specific survival figures. It is scientifically unclear which patients progress quickly to cirrhosis and which remain stable for decades – each case varies greatly.

Phase 2: Immune-active phase (HBeAg-negative, elevated transaminases)
Sometimes the virus changes or the immune system responds differently. HBeAg may disappear, but the virus remains. This phase can last years and is also called 'active chronic hepatitis'. The liver becomes noticeably inflamed (chronic hepatitis), which can contribute to scarring.
**Symptoms in this phase: **
- Fatigue, sometimes considerable
- Concentration difficulties
- Mild abdominal pain or pressure below the right ribs
- Nausea or digestive irregularities
- Possible yellowing of skin and eyes (jaundice), usually mild
- Joint or muscle pain
- With progression to more inflammation: fluid accumulation in the abdomen, bruising (clotting problems)
**What this means for daily life: **
Fatigue can be limiting; some people need to take breaks at work or cannot sustain certain activities. However, most people can function normally. Regular blood tests and liver ultrasounds become increasingly important, as this phase can be a sign of progressive damage. Avoiding alcohol is strongly recommended, as it worsens liver inflammation.
**Figures about this phase: **
At the population level, approximately 30–40% of patients in the immune-active phase eventually progress to cirrhosis; this can happen within 5–30 years, depending on many factors (age, sex, HIV status, underlying lifestyle). Exact median survival for this phase alone is difficult to estimate from a single study. Studies from 2026 emphasize that viral load and markers of liver inflammation predict outcomes better than symptoms alone.

Phase 3: Immune tolerance recurrence (HBeAg-positive, normal transaminases)
Some patients – especially those who acquired the disease at a young age – can have long periods with extremely high viral load but at the same time normally functioning transaminases and little inflammation activity. This can persist for decades.
**Symptoms in this phase: **
- Usually no symptoms
- Normal energy levels
- However, the virus is very active; transmission risk is high
**What this means for daily life: **
This phase feels harmless – you generally feel well. But because the virus is strongly active, the risk of transmission to others is higher. Also, the risk of liver cancer can gradually increase. Regular blood tests remain crucial, because without monitoring, chronic inflammation can quietly cause damage. Alcohol prevention and a healthy lifestyle are important.
**Figures about this phase: **
This phase can last 10–50 years or longer. The likelihood that patients in this phase develop cirrhosis varies: studies suggest that approximately 10–25% show progression at some point, but many remain stable for decades. No reliable population-wide survival figures are known for this stage in isolation.

Phase 4: Cirrhosis and decirrhosis
If the liver is damaged for years by chronic hepatitis, cells can form scars (fibrosis) that eventually disrupt the normal liver structure (cirrhosis). This is a critical step; cirrhosis can lead to liver failure and cancer.
**Symptoms in cirrhosis stage:**
- Severe fatigue
- Abdominal swelling (ascites) due to fluid imbalance
- Fluid buildup in legs and ankles
- Confusion or memory difficulties (hepatic encephalopathy)
- Easy bleeding or bruising
- Red spots on skin (spider angiomas)
- Jaundice (yellowing of skin and eyes)
- Thinned arms and legs with thicker abdomen
- Nausea, vomiting, possibly blood in vomit
- Recurrent infections
**What this means for daily life: **
Cirrhosis significantly limits daily life. Work and physical exertion become difficult. You are tired and must be careful about infections. Certain foods must be avoided (salt, red meat). Medications must be used very carefully because the liver cannot break them down well. Doctor visits become frequent. The psychological burden can be great, because cirrhosis is a serious diagnosis.
**Figures about this phase: **
Patients with untreated cirrhosis have a median survival of approximately 10–15 years with continued exposure to the virus, but this varies greatly. In patients on supportive antiviral therapy, some can remain stable for decades; others deteriorate faster. Studies from 2024–2026 show that viral load control and treatment of complications greatly improve outcomes. The risk of hepatocellular carcinoma (liver cancer) is approximately 2–5% per year in cirrhotic patients – again: these are averages, individual risks vary greatly.
Some patients can – if well treated – achieve "decirrhosis," where scar tissue partly disappears; however, this is rare and requires long-term very effective viral suppression.

Phase 5: Hepatocellular carcinoma (HCC)
Chronic hepatitis B significantly increases the risk of liver cancer, especially with cirrhosis. This can develop even in patients with well-controlled viral load.
**Symptoms of HCC:**
- Rapid weight loss
- Severe abdominal pain
- Persistent nausea
- Worsening of jaundice (yellowing)
- Mass felt in the abdomen
- Anemia (paleness, fatigue)
**What this means for daily life: **
Diagnosis of liver cancer changes everything. Treatment (surgery, radiation, medications) becomes intensive. Energy and well-being decline. Many patients must give up daily activities.
**Figures about this phase: **
In patients with cirrhosis from hepatitis B, the annual risk of HCC is approximately 2–5% per year. Studies from 2026 show that regular screening (every 6 months) and early detection improve outcomes. Median survival after HCC diagnosis depends on stage and treatment; untreated, this is usually several months, with treatment 2–5 years or more. These are population averages; individual prognosis depends on many factors.

When to contact your doctor
Contact your doctor immediately if you:
- Get sudden severe abdominal pain
- Vomit blood or the vomit looks like coffee grounds
- Become very confused or do not recognize your identity
- Have severe shortness of breath or chest pain
- Have fever above 38.5 °C (sign of infection)
- Yellowing of skin and eyes becomes noticeably worse
- You can no longer eat or are experiencing fluid loss
Regular follow-up appointments are important – keep them, even if you feel well. Blood work and ultrasound help detect damage early.
