The pancreas is an organ behind the stomach that has two important functions in the body. It makes and releases enzymes that help break down food during digestion. Lipase breaks down fats, amylase breaks down carbohydrates/sugars, and protease breaks down proteins. It also releases hormones that help to control blood sugar (glucose) levels. Insulin decreases high blood sugar levels, while glucagon increases low blood sugar levels. Disorders of the pancreas can create major problems with digestion and blood sugar control and need treatment to avoid many related health complications.
Disorders of the pancreas include pancreatitis, pancreatic cancer or neuroendocrine tumours, cysts, exocrine pancreatic insufficiency, and diabetes. Certain health conditions such as Cystic Fibrosis can significantly increase the risk of problems with the pancreas. Tumours and cysts will often require surgical removal or drainage. While changes in diet and lifestyle (healthy foods, avoiding smoking and alcohol, exercise) can help improve symptoms associated with pancreatic disorders, some form of medication treatment is usually needed.
Pancreatitis is a painful inflammation in the pancreas. Symptoms include tenderness and pain in the upper abdomen radiating to the back, fever, rapid heart rate, nausea and vomiting, oily diarrhoea, weight loss with no known cause, and abdominal pain that worsens after eating. It can be acute, meaning it comes on suddenly and lasts for a few days, or chronic, lasting for months or even years. Acute pancreatitis may be due to gallstones, high triglyceride or calcium levels in the blood, high alcohol consumption, certain medications, infection, or injury to the abdomen. Chronic pancreatitis may be hereditary (genetic, passed from a family member) or autoimmune (a condition where the immune system attacks the body). Medications used for pancreatitis treat the symptoms and underlying causes.
Exocrine pancreatic insufficiency occurs when the pancreas does not produce enough digestive enzymes (amylase, lipase, protease), or the enzymes do not work well enough to adequately digest food. This can be caused by chronic pancreatitis, cystic fibrosis, diabetes, celiac disease, inflammatory bowel disease, weight loss surgery, or pancreatic cancer. This causes malnutrition and associated complications.
Diabetes is a chronic disease that results in uncontrolled blood sugar, usually hyperglycaemia, or high blood sugar/glucose, which can cause many serious complications throughout the body. Type 1 diabetes usually occurs during childhood and is characterized by the inability to make insulin. The symptoms (excessive thirst and urination, tiredness/weakness, blurred vision) are usually more severe and come on suddenly. In type 2 diabetes, which usually occurs in adulthood (though cases of type 2 diabetes in children are rising) the body is unable to use the insulin it produces effectively, and the symptoms usually have a slower onset. Gestational diabetes is diabetes that occurs during pregnancy and may go away after giving birth. Often, it is possible to prevent disease and help control blood sugar in type 2 diabetes with diet, exercise, and maintaining a healthy weight. However, many patients will need medication to help control blood sugar. Type I diabetics are considered “insulin dependent,” and will need medication treatment with insulin injections.
Pancreatic cancer is an uncontrolled growth of cancer cells (tumour) starting in the pancreas and usually spreading to other parts of the body (metastasis). It can be very difficult to detect in its early stages due to the position of the pancreas in the abdomen and because early on, there aren’t usually any symptoms. Unfortunately, pancreatic cancer is usually in an advanced stage before it is diagnosed. Treatment usually consists of surgery to remove the tumour(s) or part or all of the pancreas, radiation therapy, and chemotherapy (medication that destroys cancer cells). Chemotherapeutic drugs can be given orally or as injections or infusions, and some common medications that may be used to treat pancreatic cancer include gemticabine, capecitabine, paclitaxel, fluorouracil, irinotecan, and oxaliplatin. Usually, treatment consists of a combination of multiple chemotherapy drugs given on a particular schedule. Chemotherapy may cause many side effects, and medications to help manage these such as pain relievers, nausea medications, allergy medications, or corticosteroids are often given.
Side effects are possible with most medications. Some common ones you may experience while taking medications for disorders of the pancreas include:
Some serious, but rare side effects associated with these medications are discussed below:
It is important to maintain a healthy lifestyle, including a healthy diet, regular exercise, or avoiding smoking and drinking large amounts of alcohol to help keep your pancreas healthy and decrease the risk of serious health problems associated with the pancreas. Fortunately, there are many treatment options available to help you manage many problems with the pancreas. It is important to follow up with your healthcare provider regularly and take your medications exactly as prescribed.
