Why Do Birds Have More Liver Enzymes?

Liver disorders in birds can be caused by various factors, including bacterial, fungal, viral, protozoan, and parasitic infections, tumors, metabolic disorders, circulatory disturbances, nutritional deficiencies or excesses, and a variety of enzymes. Avian liver disease in birds is usually slow, progressive, with hen birds being more affected than cock birds. Elevated plasma enzyme activities indicate recent hepatocellular damage and may create adequate suspicion of liver disease.

Fatty liver disease arises when a parrot consumes excessive fat or carbohydrates, leading to fatty deposits in the liver. Birds are more likely to develop a fatty liver than other birds. Elevations in plasma ALP activity in birds are more common. Hepatic lipidosis is most commonly seen when a diet containing excessive fat is consumed (seed majority diet) or when there is an increase in fat break down.

Elevations in bile acids appear to be a sensitive indicator of hepatic disease and reduced hepatic function in birds except in the case of iron. AST and bile acids are the most sensitive indicators of liver disease in birds, as they are not liver-specific and can be increased in any septic or inflammatory condition. Fatty liver disease in birds is often the result of malnutrition, but it can be treated with proper nutrition if detected early enough.

Liver problems can also cause tumors, loss of appetite, lethargy, and depression. Many birds are obese or overweight, and the liver is enlarged due to fatty infiltration. Moderate to marked elevations may indicate severe loss of functional hepatic mass, as can occur with hepatitis, bile duct hyperplasia, or severe cirrhosis. All birds with AST, GLDH, or bile acid values above the reference range were identified. Muscle damage can cause a concurrent increase in AST.

What is the most common cause of elevated liver enzymes?

Common causes of elevated liver enzymes include: Nonprescription pain medicines, particularly acetaminophen (Tylenol, others). Certain prescription medicines, including statins, which are used to control cholesterol. Drinking alcohol.

Can fatty liver be reversed in birds?

With diligent care, veterinary supervision, exercise, correct nutritional support and appropriate medications, it is possible to reverse the affects of hepatic lipidosis, but some permanent liver damage may occur.

What disease attacks a birds liver?

• Nutritional or metabolic
• Hepatic lipidosis
• Hepatic lipidosis is most commonly seen when a diet that contains excessive fat is consumed (seed majority diet), or when there is increase in fat break down due to diabetes or egg laying.
• Gout due to kidney disease
• Toxins
• Heavy metal toxicity (lead, copper, iron), plant toxin (oleander, avocado), phosphorus, vitamin D3 toxicity (common when over-supplemented)
• Parasitic, bacterial (including chlamydia psittacii), or fungal

We will often recommend biochemical and haematological evaluation of your bird’s blood, as this is a valuable tool to assess the health of the liver. It provides insight into whether there is liver cell damage, liver function deficits, impaired bile flow, or impaired fat metabolism.

Depending on the blood results, further diagnostic testing may be recommended to obtain more information. Commonly these tests include radiographs (x-rays), ultrasound, and/or a liver biopsy (endoscopic or surgical).

What is the best marker of liver disease in birds?

As interpretation of avian chemistry results differs from mammalian chemistry, a brief explanation of the various tests is included as follows:

AST and bile acids are the most sensitive indicators of liver disease in birds.

GLDH also has high activity in renal tissue in birds but most of the enzyme is excreted directly into urine and never reaches the blood.;

What food causes elevated liver enzymes?

Eating certain kinds of food can increase the risk of developing NAFLD. Foods that are high in sugar, fat, and salt put extra stress on the liver. Fast food, packaged foods, and processed foods tend to contain a lot of these elements.

What causes liver disease in poultry?

• High calorific intake.
• Hormonal factors.
• Nutritional factors.
• Toxicological causes (poisons or contaminated feeds).
• Excessive fatty foods (sunflower seeds, suet).
• Lack of exercise/sedentary lifestyle.
• Lack of biotin and Choline Chloride in the food, both necessary for fat metabolism (present in quality poultry feeds).
• Hereditary factors.

• Leukosis caused by avian retroviruses (Marek’s disease).
• Toxins (feed, environment, etc.).
• Sarcoma (liver tumour).

What virus causes elevated liver enzymes?

• Non-alcoholic fatty liver disease (NAFLD). This is probably the main reason for elevated liver enzymes in children in the U. S. today. Mild forms of this disease are very common
• the more serious form that over many years can lead to cirrhosis (scarring) and liver failure is called non-alcoholic steatohepatitis (NASH).
• Certain medicines. Drug-induced liver injury (DILI) is another possibility. Medications that can affect the liver include those for attention-deficit/hyperactivity disorder, such as atomoxetine
• antibiotics, such as erythromycin or minocycline
• anticonvulsants, such as valproic acid
• or products containing acetaminophen. Drug-induced liver injury is often mild, but sometimes it can be severe.
• Viral infections. Many viruses can temporarily increase liver enzyme levels. These include rhinovirus (common cold) or Epstein-Barr virus (EBV), the virus that causes mononucleosis (“Mono”).

Rarely are elevated liver enzymes due to a serious or even life-threatening condition. Some of these less common causes include:

• Autoimmune hepatitis (AIH)
• Hepatitis B and C
• Diseases of the bile ducts, such as biliary atresia, choledochal cyst, or bile duct blockage from a gallstone or from pancreatitis
• Diseases of other organs, such as celiac disease, a disorder of the intestine (gut)
• Genetic (inherited) conditions, such as alpha-1 antitrypsin (AAT) deficiency (where a protein gets produced incorrectly and “gets stuck” in the liver), hemochromatosis (too much iron) or Wilson disease (too much copper)

What causes an enlarged liver in birds?

Obesity with the resultant fatty liver disease is one of the most common nutritional diseases that we see in birds, particularly in parakeets and cockatiels. This is due to the high fat seed diet that they normally consume.

Traditionally, birds have been provided with seeds and water as their main diet. This is woefully inadequate. Perhaps it was convenient to feed dried seed, however, in the wild birds eat a more varied diet, eating dried seeds only in a time of hardship. Seed is high in fat (leading to obesity and binding to calcium — leading to lowered blood calcium) and seed is low in vitamin A (proper levels of vitamin A help to provide resistance to disease).

If the fat content of the diet is too high, the fat accumulates in the bloodstream and is deposited throughout the body, especially in the liver, as well as resulting in the development of fat deposits/obesity. The fat slowly infiltrates into the liver over time so that there is less and less functional liver tissue left until normal body metabolism is disrupted and the bird is subject to secondary disease(s). The bird may even be unable to withstand simple stress and sudden death can occur.

As this fat accumulates, it forms fat deposits on the chest and abdomen so that the bird has a pronounced/distended chest or belly. Due to the excessive weight the bird may be unable to fly or tires easily. Fat accumulation may also occur around the heart, interfering with normal function.

How to treat liver disease in birds?

How are liver disorders in birds treated?. The range of treatments varies depending on the specific problem and may include modifying the diet, nutritional supplementation, increased exercise, and possibly hospitalization with supportive therapy (fluids and vitamins) plus antibiotic, antiviral, or antiparasitic medications as needed. Sometimes, the condition cannot be cured, only managed to improve the bird’s quality of life. The use of homeopathic or natural products may be beneficial to support an ailing liver but should only be used under the guidance of an avian veterinarian.

What causes liver issues in birds?

What causes liver disorders in birds?. Liver disorders can be caused by bacterial, fungal, viral, protozoan, and parasitic infections. Other causes of liver disease include tumors, metabolic disorders, circulatory disturbances, nutritional deficiencies or excesses, and a variety of toxicities such as heavy metal toxicity, mycotoxins (toxins from mold), plant toxins, and toxic chemicals.

Diets that are composed of mainly seeds and peanuts are commonly associated with fatty liver disease in pet birds. This can lead to cirrhosis (scarring) or fibrosis (excessive tissue buildup) of the liver.

What are the clinical signs of liver disorders in birds?. If your bird is suffering from a liver disorder, you may see vague signs such as fluffed feathers, listlessness, depression, and/or anorexia (decrease in food consumption). Birds with advanced liver disease often exhibit wet droppings, yellow or green stained urates (they are white when normal), increased thirst, regurgitation, difficulty breathing, and/or a swollen, puffy abdomen.
