READER'S PAINFUL PANCREAS IS NOT A PRE-CANCEROUS CONDITION
Question: I was recently diagnosed with what the
doctor called acute pancreatitis. This sounds really scary to me.
As you know, pancreatitis is a very painful disease -- but that's not what's
worrying me right now. I'm worried that it might lead to pancreatic cancer,
which I know can be very deadly. Should I be worried about this?
Answer: The pancreas has two main functions. First,
it produces insulin, which helps the body's cells efficiently absorb sugar (glucose)
from the blood. Second, it produces enzymes that are used in the digestion of
food. This essential gland is located in the abdomen behind the stomach. Because
of its location, an inflamed pancreas -- what doctors call pancreatitis -- produces
abdominal pain, back pain, nausea and vomiting. And, because of impaired insulin
production, pancreatitis can also cause an increase in blood sugar.
Pancreatitis is classified as "acute" when you have a first attack
and "chronic" when additional episodes have occurred. Your doctor
diagnosed your case as acute pancreatitis because you've had just one attack
of this painful condition. This seemingly simplistic differentiation between
the two types of pancreatitis is important because acute pancreatitis has several
potential causes, while the chronic disease is due to alcohol use in almost
90 percent of the cases.
Gallstones can cause acute pancreatitis. The exact mechanism by which this occurs
is debated by medical experts, but the most widely accepted theory states that
the condition begins with small gallstones. These stones are then expelled from
the gallbladder and travel down the bile duct, the tube that connects the gallbladder
to the duodenum (the fist portion of the small intestine). The end of this duct
also connects to the duct that drains enzymes from the pancreas. It is postulated
that the passage of small gallstones can temporarily block the area where these
two ducts come together. This blockage, then, causes bile to back up
into the pancreas and, thereby, activates the pancreatic enzymes inside the
pancreas instead of within the small intestine. Thus the pancreatic enzymes
begin to digest the pancreas itself, causing inflammation in the gland. In other
words, pancreatitis.
Acute pancreatitis, as I said, has many causes -- one of which can be excessive
consumption of alcohol. The exact mechanism by which alcohol irritates the pancreas
isn't known, either. For most drinkers, though, it takes heavy alcohol use for
more than a decade to cause the damage necessary to produce pancreatic pain.
Pancreatitis is caused by other conditions as well. Chronic malnutrition is
a common cause in developing countries, but fortunately, it is an uncommon one
here. There is even a rare inherited form caused by a genetic alteration that
produces a specific enzyme defect.
Pancreatitis is serious regardless of the cause. The pain can be quite intense,
but fortunately, it isn't always. Nausea and vomiting from this disease often
produce significant dehydration and altered balance of the blood salts called
electrolytes. This problem typically requires treatment with intravenous, or
IV, fluids. Elevated blood sugar from pancreatitis is usually controlled by
the administration of insulin.
Although all of this sounds pretty bleak, there are two pieces of good news.
First, almost everyone recovers from the first attack of pancreatitis if he
or she addresses the underlying cause -- has the gallbladder removed, stops
drinking alcohol, etc. The other positive note is that as painful as acute pancreatitis
can be, it doesn't lead to pancreatic cancer. There may be a correlation between
chronic pancreatitis and pancreatic cancer, however.
My advice to you is two-fold: Take steps to address the cause of your pancreatitis,
and avoid lapsing into chronic pancreatitis.
