Disease at a Glance
Summary
Budd-Chiari syndrome is a rare disorder characterized by obstruction of the veins of the liver that carry the blood flow from the liver. When the blood flow out of the liver is impeded, blood backs up in the liver, causing it to enlarge (hepatomegaly). The spleen may also enlarge (splenomegaly). This backup of blood increases blood pressure in the portal vein, which carries blood to the liver from the intestines (portal hypertension), and result in dilated, twisted veins in the esophagus (esophageal varices). Portal hypertension, leads to fluid accumulating in the abdomen (called ascites). The clot may extend to also block the inferior vena cava (the large vein that carries blood from the lower parts of the body to the heart). Varicose veins in the abdomen near the skin's surface may develop and become visible. In some cases, scarring of the liver (cirrhosis) occurs. Other symptoms may include fatigue, abdominal pain, nausea, jaundice and bleeding in the esophagus. The severity of the disorder varies from case to case, depending on the site and number of affected veins. It most often occurs in patients which have a disorder that makes blood more likely to clot, such as those who are pregnant or who have a tumor, a chronic inflammatory disease, a clotting disorder, an infection, or a myeloproliferative disorder. In about one third of the cases, the cause of Budd-Chiari syndrome is unknown.

When Do Symptoms of Budd-Chiari syndrome Begin?
Symptoms of this disease may start to appear at any time in life.
The age symptoms may begin to appear differs between diseases. Symptoms may begin in a single age range, or during several age ranges. The symptoms of some diseases may begin at any age. Knowing when symptoms may have appeared can help medical providers find the correct diagnosis.

Digestive System
The digestive system is made up of the esophagus, stomach, intestines, liver, pancreas, and gallbladder. Common symptoms of problems in the digestive system include blood in the stool, changes in bowel habits, severe abdominal pain, unintentional weight loss, or heartburn. Diseases affecting the digestive system may be diagnosed and treated by a gastroenterologist (GI specialist).

How Can Patient Organizations Help?
Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
- Ways to connect to others and share personal stories
- Easy-to-read information
- Up-to-date treatment and research information
- Patient registries
- Lists of specialists or specialty centers
- Financial aid and travel resources
Please note: GARD provides organizations for informational purposes only and not as an endorsement of their services. Please contact an organization directly if you have questions about the information or resources it provides.
View GARD's criteria for including patient organizations, which can be found under the FAQs on our About page. Request an update or to have your organization added to GARD.

Participating in Clinical Studies
Clinical studies are part of clinical research and play an important role in medical advances, including for rare diseases. Through clinical studies, researchers may ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
- Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
- Observational studies involve recording changes over time among a specific group of people in their natural settings.
Why Participate in Clinical Studies?
People participate in clinical trials for many reasons. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Healthy volunteers may participate to help others and to contribute to moving science forward.
To find the right clinical study we recommend you consult your doctors, other trusted medical professionals, and patient organizations. Additionally, you can use ClinicalTrials.gov to search for clinical studies by disease, terms, or location.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
Join the All of Us Research Program!
The All of Us Research Program is inviting 1 million people from all backgrounds across the U.S. to help build one of the most diverse health databases in history. Researchers will use the data to learn how our biology, lifestyle, and environment affect health. This may one day help them find ways to treat and prevent diseases.
