    Understanding the Pancreas: Functions and Health


    The pancreas is a sizable gland with a shape reminiscent of a tadpole, located deep within the abdominal cavity. It is quite essential for the processes of digestion and the regulation of blood sugar levels in our body.


    Diagnosing pancreatic disease can be challenging because of the organ’s positioning. However, there are actions you can take to lower your likelihood of experiencing these issues.







    What is a Pancreas?







    The pancreas is a big gland located behind your stomach. It resides in the curve of your duodenum, which is the initial segment of your small intestine. Your pancreas functions as a dual organ. Your pancreas serves two primary roles, and it produces:



    1. Enzymes (amylase, lipase, trypsin) that assist in the digestive process which includes the breakdown of carbohydrates, proteins, and fats (exocrine system).

    2. Hormones (insulin, glucagon, somatostatin) to regulate the levels of sugar present in your blood (endocrine system).


    Function of Pancreas







    What role does the pancreas play in our body?


    The pancreas is an essential organ that keeps your body in balance and helps support other organs such as your heart, liver, and kidneys.


    One of the primary functions of your pancreas is to assist in the digestive process and it is responsible for releasing hormones that help regulate blood sugar levels.


    Help with the process of digestion


    Your pancreas produces approximately 1-4 liters of enzyme-rich digestive juice daily to help you digest nutrient breakdown from consumed foods. The specific amount can change based on the quantity of food you consume.


    Following a meal, it’s likely that you don’t give much thought to the process of digestion unless you experience discomfort or develop indigestion.


    However, multiple organs collaborate to assist in the breakdown process. Let’s explore what happens when food enters your stomach:


    The Digestive Process: A Step-by-Step Breakdown



    • Step 1: Pancreatic Juice Release: After eating, your pancreas releases digestive juice into small ducts that flow into your main pancreatic duct.

    • Step 2: Duct Connection: Your main pancreatic duct merges with the bile duct. This duct transports bile from your liver to the gallbladder.

    • Step 3: Bile Transport: Bile travels from your gallbladder to the duodenum (small intestine’s first section).

    • Step 4: Digestive Breakdown: Pancreatic juice and bile enter the duodenum to breakdown food into nutrients.


    Pancreas Create Hormones







    The pancreas produces important hormones, such as insulin and glucagon, which play a crucial role in regulating the sugar levels in your bloodstream.


    When your blood sugar levels rise, your pancreas produces insulin to help bring them back down. When the blood sugar levels drop, your pancreas generates glucagon to help raise them back up.


    Maintaining balanced blood sugar is essential for your body to function effectively, ensuring that vital organs such as your heart, liver, kidneys, and brain operate smoothly.


    Anatomy of Pancreas


    Location of Pancreas in Body


    Your pancreas is located deep within your abdomen, positioned behind the stomach and in front of the spine. The spleen, gallbladder, and liver surround the pancreas.


    Anatomy of Pancreas


    Pancreas has various components, each fulfilling a distinct function.



    1. Head: The head of the pancreas is located on the right side of the abdomen, which measures about 2-3 centimeters adjacent to the small intestine.

    2. Body: The pancreas central portion measures about 10-12 centimeters long and it contains most of the pancreatic tissue.

    3. Tail: The pancreas’ tail is about 2-3 cm in diameter, and it extends to the left side of the abdomen, adjacent to the spleen.

    4. Pancreatic Duct: The pancreatic duct runs the full length of the pancreas.


    How does the pancreas appear?


    The pancreas is a glandular organ, that measures about 6-10 inches (15-25 cm) in length and is situated in the abdominal cavity.


    Your pancreas has a unique shape that resembles a tadpole, featuring a thicker head and a thin tail. Its surface is uneven, resembling the texture of a corn cob.


    The pancreas constitutes around 0.1-0.2% of total body mass, which is roughly the weight of a small banana.


    Common Pancreatic Disorders and Symptoms







    The pancreas is tucked away in your body, but it can still face issues. These issues can go from short-term inflammation of the pancreas to lasting illnesses.


    Which diseases and disorders can compromise the pancreas?


    Your pancreas can be affected by various conditions and ailments that can influence its functionality, including:



    • Chronic pancreatitis is persistent inflammation. It occurs due to excessive alcohol consumption, which may lead to discomfort, digestive issues, and the onset of diabetes.

    • Pancreatic cancer is a serious condition, and it is hard to detect in the early stages. It can also spread to other organs before being noticed. Signs and symptoms of pancreatic cancer may include pain in the abdominal area or back, weight loss, and jaundice.

    • Pancreatic cysts are quite common among individuals. They are fluid-filled sacs that could potentially contain precancerous cells. Regular checks and tests, like endoscopic ultrasound and biopsy, are important to keep an eye on these cysts.

    • Type 1 diabetes occurs when the pancreas is unable to generate adequate insulin levels.

    • Type 2 diabetes happens when the body makes insulin but does not use it well.

    • Hypoglycemia (low blood sugar) happens when blood glucose levels drop under 70 mg/dL, which can pose risks to the brain and essential organs. It is typically associated with diabetes, yet it can also impact individuals who do not have the condition.

    • Hyperglycemia (high blood sugar) arises when blood sugar levels exceed 180 mg/dL, which can lead to harm to organs and tissues. This situation frequently arises in diabetes when there is an insufficient amount of insulin available. If left unaddressed, it may lead to significant complications such as diabetic ketoacidosis.


    Symptoms of Pancreatic Disease


    Diseases that impact the pancreas can have strange symptoms. This can make it difficult to spot them early. It’s very important to recognize the warning signs. If you observe any of these signs, it is recommended to consult a physician.

    4. Endoscopic Ultrasound (EUS)

    5. Positron Emission Tomography (PET) scan


    Blood Tests:



    1. Amylase and lipase levels (pancreatitis)

    2. Glucose tolerance test (diabetes)

    3. Pancreatic enzyme tests (elastase, trypsin)

    4. Tumor marker tests (CA 19-9)


    Endoscopic Procedures:



    1. Endoscopic Retrograde Cholangiopancreatography (ERCP)

    2. Endoscopic Ultrasound (EUS)

    3. Pancreatoscopy


    Pancreatic Function Tests:



    1. Pancreatic stimulation test (measures enzyme secretion)

    2. Glucose tolerance test (assesses insulin function)


    Biopsy and Histopathology:



    1. Fine-needle aspiration biopsy (FNAB)

    2. Core needle biopsy


    Other Tests:



    1. Stool tests (elastase, fat content)

    2. Pancreatic juice analysis

    3. Genetic testing (hereditary conditions)


    Treatment Options: From Medication to Surgery


    Treatment for pancreatic diseases varies depending on the condition, how far it has progressed, and the person’s health. Your healthcare providers address pancreatic conditions through various approaches, tailored to the specific condition at hand.


    Treatment Options by Condition:



    • Diabetes: Insulin replacement therapy

    • Pancreatic Cancer: Chemotherapy, radiation therapy, and surgery

    • Pancreatitis: Dietary modifications, medications, and surgery (in severe cases)

    • Advanced Cases: Pancreas transplant or pancreatectomy (partial/total removal)


    Islet Cell Transplant: Transplanting islets of Langerhans cells into the liver


    Medication for pancreatic treatment


    There are several medications available that can help in managing pancreatic conditions:



    1. Pain management: analgesics, narcotics

    2. Pancreatitis: anti-inflammatory medications

    3. Diabetes: oral hypoglycemics, insulin

    4. Enzyme replacement: pancreatic enzymes

    5. Antibiotics (infections)


    Surgical Treatment for Pancreatic Conditions


    In many cases, surgical procedures are essential for addressing pancreatic issues, serving either as the main approach or alongside additional treatment methods. The objective of surgical intervention is to eliminate unhealthy tissue, alleviate symptoms, and enhance overall quality of life.


    Various procedures are employed, depending on the condition’s severity and location.



    • Pancreatectomy, involving partial or total removal of the pancreas, is commonly performed for pancreatic cancer, severe chronic pancreatitis, and benign tumors.

    • The Whipple procedure, a complex operation removing the head of the pancreas, duodenum, bile duct, and gallbladder, is generally reserved for pancreatic cancer and ampullary cancer.

    • Distal pancreatectomy, involves the surgical removal of the body and tail of the pancreas, serving as a treatment option for pancreatic cancer, benign tumors, and cysts.

    • Pancreas transplantation, either alone or simultaneously with kidney transplantation, offers a treatment option for severe type 1 diabetes and end-stage renal disease.

    • Islet cell transplantation, involving the transfer of insulin-producing cells into the liver, provides an alternative for managing severe type 1 diabetes and chronic pancreatitis.

    • Necrosectomy, the removal of dead pancreatic tissue, is performed in cases of severe acute pancreatitis or infected pancreatic necrosis.


    Surgical approaches include open surgery, laparoscopic surgery, and robotic-assisted methods, each with varying benefits and risks. It’s important to consult with a qualified healthcare professional to find the best surgical approach tailored to your specific pancreatic condition.
