# Symptoms and phases of primary sclerosing cholangitis
In primary sclerosing cholangitis (PSC), the disease progresses in different patients at different times and at varying rates. Some people have mild symptoms for years, others notice a faster deterioration. This tab describes the phases in which the disease usually occurs and which symptoms are associated with it.
Early phase (years with no or mild symptoms)
At first, PSC **can't express itself tangively** for a long time. Many people discover the disease by chance, for example when taking blood tests for another purpose or because they are already familiar with inflammatory bowel disease (IBD, especially ulcerative colitis). This can take years before symptoms even occur.
**Symptoms that may occur: **
- Usually no significant complaints
- Occasional tiredness or unexplained tiredness
- Possibly slightly distended stomach
- Sometimes itchy, especially in the evening or after hot water
- Nocturnal sweat attacks may occur
- Mild nausea after a fatty diet
**In daily life:**
Many patients don't notice much — they mostly feel normal. The only thing you notice is sometimes a slowness or that you are tired faster than usual. This can go on for years.
**What we know about this phase: **
When PSC is detected by tests (such as IBD patients who are being screened), many patients are still at an early stage. How long someone stays in this phase varies enormously. Some have stable values in their blood tests for years, others see step-by-step deterioration. This depends on many personal factors: the level of inflammation in your bile duct, your immune system, possible genetic predisposition and still unknown factors. There are no precise predictions possible per person.

Phase with progressive cholestasis (rising bile poisoning)
In this phase, blood disorders become clearer and more symptoms arise due to the accumulation of bile and toxic substances.
**Symptoms:**
- **Itching (pruritus) :** This is the most annoying symptom for many people. The itching can be mild or very intense, especially in the evening and in warmth. It can make bile drugs and fatty foods worse
- **Tiredness and mental fog: ** Real, profound tiredness (not just a bad night's sleep). Also concentration problems, forgetfulness, slowness of thinking
- **Yellow urine and pale stools: ** Due to accumulation of bile
- **Possible slight yellowing** of skin and eyes
- **Stomach inflammation** (for no apparent reason)
- **Nausea and not eating so well**
- **Weight loss** (because you eat less and absorb less)
- **Bone pain** and possible weakening of bones (osteoporosis)
- **False attacks: ** White-yellow deposits around your eyelids and skin (xanthomas) may occur
- **Sometimes pain in the upper right abdomen**
**In daily life:**
The itching can be so bad that you wake up at night and can't sleep. Because you are tired and unwell, working, housekeeping and social activities become harder. Many people withdraw a bit because of fatigue. Certain foods (especially fat and heavy) are immediately felt (stomach, nausea).
**What we know about this phase: **
The blood value pattern (increased liver enzymes, increased bilirubin) gives doctors a hint of how fast the disease is progressing. But this doesn't say much about one person either. Some stabilize for months, others deteriorate smoothly. Studies such as liver elasticity (“liver stiffness”) provide more insight into how much scar tissue already exists, but that also varies greatly. The duration of this phase can be from months to years. A lot depends on whether you have treatments that help (such as ursodeoxycholic acid), whether your gut is well controlled (with IBD), and how your immune system responds.

Phase with onset of liver disease (fibrosis and early cirrhosis)
As bile and inflammation act on the liver cells longer, scar tissue develops. The liver slowly loses its ability to work properly.
**Symptoms:**
- All previous symptoms remain but intensify
- **Itching can no longer be controlled** with normal measures
- **Severe fatigue:** You are almost constantly exhausted, even after rest
- **Concentration problems and "brain fog":** Many patients report this as troublesome – you can think less, you forget things, you are slower
- **Abdominal swelling** (ascites): The abdomen swells up because fluid accumulates
- **Swollen legs and feet**
- **Muscle atrophy:** You notice you have fewer muscles, feel weaker
- **Fluid retention:** You gain weight from fluid, not because you eat a lot
- **Possible bleeding** (nosebleeds, gum bleeding or bruising) because your liver no longer produces clotting factors properly
- **Changes in bowel movements:** Much too dark or different
- **Confusion in severe cases**
- **Sleep problems** that are not only caused by itching
**In daily life:**
This becomes limiting. You can no longer do everything – working long days becomes difficult, household tasks require a lot of energy. You don't feel good in your body with the abdominal swelling. The itching and fatigue make your mood worse. Many patients say they isolate themselves because they don't feel well and can plan less.
**What we know about this phase: **
This is the phase when doctors increasingly check liver function and sometimes perform biopsies or elastographies (measurements of scarring). The severity of symptoms is strongly related to how quickly scars form. In some people this happens over years, in others faster. This is also the moment when doctors become more alert to cholangiocarcinoma, which occurs more frequently in PSC than in the healthy population. This is reason for regular screening.

Phase with severe liver damage (advanced cirrhosis)
This is when the liver is so damaged that it can no longer do its job properly. This can occur over months or years, depending on how quickly the disease progresses.
**Symptoms:**
- **All previous symptoms worsened**
- **Possible hepatic encephalopathy (liver brain disease):** Confusion, disorientation, sleep reversal, behavioral change. This feels like 'not being yourself'
- **Bleeding from the esophagus (varices):** This is an emergency – vomiting blood or very dark bowel movements
- **Kidney failure:** The kidneys work poorly because the liver doesn't work well
- **Infections of abdominal fluid (spontaneous bacterial peritonitis):** Sudden fever, abdominal pain, feels acutely unwell
- **Very intense itching:** Almost uncontrollable
- **Complete exhaustion:** Can barely do anything independently
- **Weight loss and muscle loss:** Your body breaks itself down
- **Yellow skin and eyes (jaundice):** Highly visible
- **Possible flu-like symptoms:** Fever, malaise, without clear reason
- **Severe fluid accumulation:** Enormous abdomen, swollen legs
- **Sometimes internal bleeding**
**In daily life:**
This is the moment when interventions are needed. Many patients can no longer work from home, require 24-hour care or hospitalization. Quality of life is severely limited. Hospital visits become more frequent, possible admissions for acute problems.
**What we know:**
This stage calls for focused conversations with your healthcare provider about what you want, because treatment choices change here. For many patients with PSC and cirrhosis, **liver transplantation** is the solution. Studies show that transplantation works well for many people when they are at this stage and have no other serious illnesses. But the waiting time, the operation itself and life after transplantation bring their own challenges.

Phase with cholangiocarcinoma as a complication
This is not necessarily a separate 'stage' of PSC itself, but a serious complication that can occur **at any time** in the disease history – even early on. Cancer in the bile duct occurs more frequently in PSC patients than in the general population.
**Symptoms of cancer:**
- **Sudden worsening of itching**
- **Sudden elevation of certain blood values** (bilirubin, liver enzymes) after a period of stability
- **Abdominal pain**
- **Weight loss** (faster than you would expect from PSC alone)
- **Nausea, loss of appetite**
- **Weakness**
- **Possible visible liver enlargement (on palpation)**
**In daily life:**
Because cancer co-occurs with existing PSC symptoms, it becomes difficult to distinguish. This is why doctors monitor regularly and are cautious about changes in your situation.
**What we know:**
The risk of cholangiocarcinoma is increased in PSC, but it is not always clear who will develop it and when. Therefore, many centers screen regularly. Early detection is important for treatment (possibly surgery), but once cancer is present, the prognosis is challenging. Liver transplantation can sometimes still help, but this depends on many factors.

When to contact your healthcare provider?
You contact your doctor or hepatologist if:
- **Sudden increase in itching** that can no longer be managed
- **Sudden increase in fatigue** or new "brain fog"
- **Vomiting blood or very dark, tar-like stool**
- **Fever, severe abdominal pain or stiffness** – especially abrupt
- **Sudden confusion or change in behavior**
- **Very severe abdominal swelling in a short time**
- **Yellow eyes/skin that worsens quickly**
- **Decline in your general condition over weeks**
- **New or pronounced abdominal pain**
- **Bleeding that does not stop**
Also less acute things worth mentioning: changes in your wellbeing where you don't feel right, persistent concentration problems, or simply if you feel that something is not right. Regular checks (blood tests, ultrasound) help your doctor monitor the situation, but your signals are important.
