# Symptoms and disease progression of primary biliary cholangitis
Primary biliary cholangitis (PBC) typically progresses through different stages. The disease develops differently in each person, and some have no symptoms for much longer than others. This description provides an overview of what tests and experiences of other patients show.
Early stage (asymptomatic)
In the very first stage, the disease has already occurred — immune cells have attacked the bile ducts — but the patient notices nothing. This can last months or years.
**What happens:**
The bile ducts in the liver are damaged by the immune system, but this does not yet lead to clear symptoms. Often PBC is discovered by chance because blood values are checked for another reason, or because PBC runs in the family.
**What you feel:**
In this stage, people usually feel fine. There are no or hardly any symptoms. Many patients do not know they have the disease until this stage has passed.
**For daily life:**
This stage does not limit daily life. People function completely normally.
**Numbers:**
Little exact data is available on this stage. Studies suggest that some patients have no symptoms for years, while the disease progresses in the background. How long this lasts varies greatly from person to person and depends on factors that are not yet fully understood. This figure says nothing about your own situation.

Stage with symptoms without cirrhosis
As the damage to the bile ducts increases, symptoms begin to appear. The liver is not yet severely damaged (no cirrhosis), but no longer functions completely well.
**Common complaints:**
- **Itching** — often the first and most bothersome symptom. This can be mild or very intense, and is experienced by many patients as the worst part of the disease. The itching can occur anywhere on the body and is usually worse in the evening. This is not the same itching as with an allergy; it occurs because bile and other substances build up in the blood.
- **Fatigue** — exhaustion that does not go away with rest. This can be mild or considerably interfere with daily life.
- **Jaundice** — yellowing of the skin and whites of the eyes, because pigments from broken down blood cells are not excreted properly.
- **Pale stool and dark urine** — because less bile reaches the bile ducts.
- **Abdominal pain** — usually mild or moderate, sometimes in the upper right abdomen where the liver is located.
- **Weight loss** — without eating less; this occurs because fatty substances are not absorbed properly.
- **Bone pain or bone weakness** — the bones can become weaker (osteoporosis) because the absorption of vitamin D worsens.
- **Dry eyes and dry mouth** — because certain glands can be affected.
- **Concentration problems** — sometimes described as "brain fog".
**What this means for daily life: **
The itching can cause insomnia and frustration. The fatigue can make work or household tasks more difficult. Many patients gradually feel less energetic. Some adjust their work and activity schedule. The itching can be socially burdensome; patients may feel ashamed or unable to sit still.
**Numbers:**
Approximately 50–70% of patients have symptoms at diagnosis. The median time from diagnosis to the development of cirrhosis (severe liver damage) is estimated at approximately 10–15 years, but this figure is an average across large groups and says nothing about one person. Much variation depends on how well the disease responds to treatment, your age, sex, and other individual factors. (Source: various observational studies, 2015–2024)

Stage with cirrhosis
When damage to the liver becomes severe, cirrhosis develops: liver tissue is replaced by scar tissue and the liver can no longer do its job properly.
**Symptoms of cirrhosis:**
- **All symptoms from the previous stage, but worse** — itching, fatigue and jaundice typically become more intense.
- **Fluid accumulation (ascites)** — fluid builds up in the abdomen, causing the belly to swell and feel tight. This can be uncomfortable and heavy.
- **Food or blood spitting from the mouth or blood in stool** — this is due to enlarged veins in the esophagus and stomach, because blood can no longer flow properly through the scarred liver. This is a serious symptom that requires immediate medical attention.
- **Confusion or sleep disorder** — because toxic substances are no longer properly filtered by the liver and reach the brain.
- **Bruising and bleeding** — the liver produces fewer clotting proteins.
- **Fluid buildup in legs and feet** — making them thicker and painful.
- **Fatigue and weight loss** — the liver cannot properly process proteins.
- **Abdominal pain** — sometimes severe.
- **Fever or infections** — the immune system becomes weak.
**What this means for daily life: **
In this phase, daily functioning is seriously impaired. People can no longer work, have many medical visits, cannot climb stairs, cannot cook themselves, feelings of dependence arise. The abdominal swelling may not fit clothing and can be painful. Confusion or sleep disorders make driving unsafe. Infection risk means caution in contacts. Many patients prepare themselves at this point for liver transplantation.
**Numbers:**
The median survival of patients with cirrhosis from PBC without transplantation is estimated at 5–10 years after diagnosis of cirrhosis, but with large variation (some longer, some shorter). This is an average across all patients together and says absolutely nothing about one person. Modern treatments and liver transplantation change these figures significantly. (Source: observational studies from 2010–2024)

End stage and liver failure
Without transplantation, PBC can eventually lead to complete liver failure, where the organ can barely function.
**Symptoms:**
- **All symptoms from previous phases, much worse** — intensive confusion, severe infections, severe bleeding, complete digestive disorders.
- **Kidney disease** — because the liver functions poorly, the kidneys can fail (hepatorenal syndrome).
- **Brain diseases (hepatic encephalopathy)** — severe confusion, sleep disorder, movement disorders, coma.
- **Infections of the abdominal cavity** — very serious.
- **Bleeding from the esophagus** — life-threatening.
**What this means for daily life: **
At this point, life is very limited. People are usually admitted to the hospital. Self-care is impossible. This stage makes liver transplantation urgently necessary.
**Numbers:**
This stage is fatal without intervention (liver transplantation) within weeks to months. With transplantation, the prognosis is considerably better; survival rates for liver transplantation in PBC are around 85–90% after 1 year and approximately 70–75% after 5 years, depending on many factors and geographic location. (Source: transplantation centers and registry data, 2015–2025) These figures also say nothing about one person.

Special complications
Some patients may develop complications:
- **Osteoporosis** — bones become fragile, fractures occur more easily.
- **Vitamin deficiencies** — especially vitamins A, D, E and K, because fats are not well absorbed.
- **Other autoimmune diseases** — some patients also have thyroid disease, rheumatoid arthritis or other autoimmune conditions at the same time.
- **Liver cancer** — the risk increases if cirrhosis develops.
- **Portal hypertension** — elevated pressure in the blood vessels of the liver, which can lead to enlarged spleen and variceal rupture in the esophagus.

When to contact your healthcare provider?
Contact if you:
- Suddenly get itching or your existing itching becomes severe and you cannot sleep.
- Spit blood or see blood in your stool.
- Get severe abdominal pain.
- Suddenly feel very tired or confused.
- Get a fever above 38.5°C.
- Your feet or belly suddenly swell significantly.
- Yellowish appearance suddenly increases.
- Have serious signs of infection (fever, chills, very ill feeling).
These are signals that the disease may have worsened or that something else is going on that needs attention.
