Jaundice (Icterus) in Dogs
- Occurrence: common
- Location of illness: Abdomen/pelvis
Jaundice, also known as icterus, is a condition characterized by a yellowish discoloration of the skin, mucous membranes, and whites of the eyes in dogs. This discoloration is caused by an elevated level of bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion. in the blood.

There are three main causes: pre-hepatic, hepatic, and post-hepatic jaundice. Pre-hepatic jaundice results from the excessive destructionDestruction means "demolition." In medicine, it refers to the destruction of cells, tissues, organs, or body parts. The growth of malignant Tumors is also usually accompanied by destruction of the surrounding tissue. of red blood cells, often due to hemolytic anemias. Hepatic jaundice is caused by liver diseases such as hepatitis or liver tumors, while post-hepatic jaundice is caused by blockages of the bile ducts. Symptoms include vomiting, weakness, yellowish discoloration of the skin and mucous membranes, and loss of appetite.

Causes
BilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion. is a yellow pigment produced during the breakdown of hemoglobinhemoglobin is an iron-containing protein in red blood cells responsible for transporting oxygen from the lungs to the body tissues and carbon dioxide back to the lungs., the red pigment in blood. Normally, bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion. is processed in the liver and excreted from the body via bile and the intestines. If this process is disrupted, it can lead to an increase in bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down.

There are three main causes of jaundice in dogs: pre-hepatic, hepatic, and post-hepatic jaundice. Pre-hepatic jaundice occurs when there is excessive destructionDestruction means "demolition." In medicine, it refers to the destruction of cells, tissues, organs, or body parts. The growth of malignant Tumors is also usually accompanied by destruction of the surrounding tissue. of red blood cells, leading to an increased production of bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion.. Common causes include hemolytic anemias, which can be triggered by autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus., infections, or toxins.
Hepatic jaundice results from damage to or disease of the liver, which impairs the processing of bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion.. Causes can include hepatitis, liver tumors, leptospirosis, or other liver diseases. These conditions can be caused by infections, genetic factors, or toxicToxic means "poisonous" and refers to substances that can have harmful effects on the body, including damage to organs, cells, or disruption of metabolic processes. substances.
Post-hepatic jaundice is caused by a blockage of the bile ducts, which obstructs the flow of bile. This can be caused by gallstones, tumors, or inflammatory conditions in the bile ducts that prevent the normal flow of bile into the intestineThe intestine is the medical term for the gut, including the small intestine (intestinum tenue) and the large intestine (intestinum crassum). It plays a central role in the digestion and absorption of nutrients..
Symptoms
The most noticeable symptom of jaundice is the yellowish discoloration of the skin, mucous membranes, and whites of the eyes. This discoloration can vary from mild to intensely yellow, depending on the severity of the condition. Affected dogs often also show general symptoms such as loss of appetite and weight loss.
Other symptoms may include lethargy, vomiting, and diarrheaDiarrhea refers to the condition of frequent, watery bowel movements, which can be a sign of infections, digestive disorders, or other health problems.. In pre-hepatic jaundice, a pale or yellowish color of the gums may also be observed, indicating anemia. In the case of post-hepatic jaundice, light, discolored stools and dark urine may occur.
In severe cases, jaundice can lead to neurological symptoms, as bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down.

Such symptoms may include convulsions or behavioral changes.
Diagnosis
The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of jaundice in dogs begins with a thorough clinical examination and a detailed historyThe medical history is the systematic collection of a patient's medical history through questioning. It includes information about previous illnesses, treatments, allergies, and lifestyle habits.. The veterinarian will examine the dog for visible signs of jaundice and other physical abnormalities.
Blood tests are crucial to determine bilirubinBilirubin is a yellow pigment that is produced when hemoglobin from red blood cells is broken down. It is further processed in the liver and then excreted via the bile. Elevated bilirubin levels may indicate liver dysfunction or impaired bile excretion. levels and identify the underlying cause. A complete blood count can provide information about anemia or infections, while a biochemical profile provides information about liver function and other organ functions.

It is the first step in the management and treatment of patients. and determine the exact cause of the liver disease.
Therapy
The treatment of jaundice in dogs depends on the underlying cause. In pre-hepatic jaundice caused by hemolytic anemia, immunosuppressants or blood transfusions may be necessary.
Hepatic jaundice requires targeted treatment of the liver disease. This may include administering antibiotics for a bacterial infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease., using medications to support liver function, or removing toxins from the body.
Post-hepatic jaundice is treated by eliminating the bile duct obstructionobstruction refers to the blockage or narrowing of a hollow organ or canal, which hinders the normal flow of liquids or gases. In dogs and cats, an obstruction can occur in the digestive tract, airways, or urinary tract and often requires immediate medical treatment.. This may require surgical removal of gallstones or tumors, or the administration of medications to relieve inflammation and promote bile flow.
Prognosis and follow-up care
The prognosis for dogs with jaundice depends heavily on the underlying cause and the severity of the condition.
