The pancreas is a large gland consisting of two main lobes and is situated in the abdomen close to the stomach, liver and small intestine. The most familiar function of the pancreas is in producing insulin, which regulates the level of glucose in the blood. Insulin is produced by the hormone producing (endocrine) cells within the pancreas known as the islets of Langerhans. Disorders in this area of the pancreas give rise to diabetes, a condition which is covered in our fact sheet on Diabetes.
The second function of the pancreas, which is equally as important, is in the production of digestive enzymes. This is referred to as the exocrine function of the pancreas. The enzymes produced by the pancreas constitute pancreatic juice, which digests food so that it can be absorbed by the body. If the enzymes are not present, an animal cannot digest or absorb food adequately.
Apart from its role in producing digestive enzymes, the pancreas is involved in:
This is basically inflammation of the pancreas and occurs either in acute or chronic forms. There are numerous causes, including bacterial infection, drug reactions and trauma. Obese animals and those fed on high fat diets appear more at risk from pancreatitis.
Symptoms are sudden in onset and the animal may appear depressed, may vomit or pass loose stools. Enzymes leak from the pancreas and damage surrounding cells. Abdominal pain may be apparent and in severe cases the animal may collapse. If you suspect that your animal is suffering from this condition, then consult your vet immediately
Long term inflammation of the pancreas is termed chronic pancreatitis. This leads to changes within the tissues of the pancreas and, ultimately, causes impairment of function with associated digestive problems
If your vet suspects pancreatitis, he may suggest taking a blood sample. By doing so, a laboratory can measure the levels of pancreatic enzymes in the blood. Abnormally high levels would indicate pancreatitis. Other factors measured in the blood may also give diagnostic indications.
Whilst acute pancreatitis requires urgent veterinary attention, chronic cases can be managed more easily.
Diet plays an important part in the control of the illness. Ideally, a high carbohydrate, low protein, low fat diet should be fed. Adult Light with Chicken and Liver canned recipe is ideal to feed in this situation, with a protein content of around 4.1% and a fat (oil) content of approximately 2.6% when measured on an ‘as fed’ basis.
In addition to dietary measures, herbal remedies can often help. Denes Greenleaf Capsuleshave a natural anti-inflammatory effect and Denes Garlic Oil Capsules can help ward off infection and control overgrowth of bacteria in the bowel.
Denes Phosphorus 30c drops are indicated in the homeopathic treatment of pancreatitis and should be given twice daily for chronic cases and four times daily for acute cases.
This differs from pancreatitis and is principally a loss of the exocrine cells that are responsible for the production of pancreatic digestive enzymes. Signs of exocrine pancreatic insufficiency (EPI) will not appear until more than 90% of the gland has been destroyed.
The most common cause of EPI is atrophy of the exocrine cells. This only occurs in the dog and the exact cause in not known. It can occur in any breed, at any age, although it is especially prevalent in young German Shepherds, where there is believed to be a genetic link to the condition. Other less common causes of EPI include pancreatitis and congenital deformities of the pancreas.
Animals with this condition are unable to either digest or absorb their food well. This can cause:
Other than by clinical signs, EPI can be diagnosed by laboratory tests. Microscopic examination of the faeces for undigested food is often used, but is rather subjective and not always accurate. More modern tests are more reliable, including measurement of enzymes (specifically trypsin and trypsinogen) in the blood by immunoreactivity, absorption tests and estimation of enzyme activity in the faeces.
The most common method of treatment involves supplementing the diet with dried pancreatic enzymes, replacing those which the animal is unable to produce. Ideally, the animal should be fed either once or twice daily, adding the powder, capsules or tablets at the recommended level to each meal. Symptoms normally resolve in a few days and, gradually, weight lost during the illness is regained. Once the symptoms are under control, treatment is maintained to prevent recurrence.
Once again, diet plays an important factor in managing this condition. The most ideal diet is easily digested and should have a low fibre content and a lower fat level. The following recipes are worth consideration:
Dog foods – canned
which are low in fat
Dry Dog food
which is low in fat when compared on a dry matter basis.
Where periodic watery diarrhoea is a problem, biscuit should be replaced with rice as the main carbohydrate source.
As well as dietary help, there are several other things you can do to manage this condition. Overgrowth of bacteria in the small intestine can be a problem with EPI. This causes diarrhoea and can often be controlled using Denes Garlic Oil Capsules, which can help inhibit the growth of unwanted bacteria. Adding Denes Probiotic+ Powder will also help, by supporting the friendly bacteria within the bowel and by limiting the growth of those which are detrimental to health. Where diarrhoea is a recurrent problem, Denes Digestion+ Powder can also help, by soothing the gut and binding the stools. Denes Milk Thistle+ Powder can also be of benefit in certain situations, as the herbs can act as a general tonic to the pancreas. Homeopathic remedies can also be useful, in particular it is worth considering Denes Phosphorus 30c drops which can support the pancreas generally and Silica 30c drops which may help improve the absorption of food
Dogs with EPI can suffer from vitamin deficiencies, particularly the B vitamins and vitamin E. Supplementation is usually recommended. Denes All-in-One+ Powder are ideal and can be added to the food on a daily basis.
