Hello - thanks for asking your question.
Although I am an internal medicine physician, please see your primary
care physician for specific questions regarding any individual cases
please do not use Google Answers as a substitute for medical advice.
I will be happy to answer factual medical questions.
You note blood in the stools, hemorrhoids, liver enzymes are mildly
elevated. You are scheduled for a colonoscopy in a few months.
It is unlikely that the elevated liver enzymes are caused by
hemorrhoids. However, it is possible that the rectal bleeding may be
a manifestation of liver disease.
Portal hypertension is a condition associated with any liver disease.
Simply put, portal hypertension is elevated pressure in the blood
vessels within the liver. The most common cause for this is cirrhosis
Portal hypertension can cause what are known as rectal varices. They
can be confused with hemorrhoids:
"Visible abdominal wall collaterals are common; veins radiating from
the umbilicus (caput medusae) are much rarer and indicate extensive
flow in the umbilical and periumbilical veins. Collaterals around the
rectum can produce rectal varices, often confused with hemorrhoids;
bleeding occasionally results."
However, it is definitely possible that your elevated liver enzymes
and hemorrhoids are unrelated. Here are some other considerations for
your elevated liver enzymes.
I have written in the past about the various causes of elevated liver
"There are many reasons that can cause elevated liver enzymes.
Medications Almost any medication can cause an elevation of liver
enzymes. Common ones include nonsteroidal anti-inflammatory drugs,
antibiotics, HMG-CoA reductase inhibitors, antiepileptic drugs, and
Alcohol abuse - In a study of hundreds of patients who had liver
biopsy confirmed liver disorders, more than 90 percent of the patients
whose AST to ALT ratio was two or greater had alcoholic liver disease.
Hereditary hemochromatosis Hereditary hemochromatosis (HHC) is a
common genetic disorder. Population screening has shown that the
frequency of heterozygotes is about 10 percent in Caucasian
populations in the United States and western Europe, with a frequency
of about 5 per 1000 (0.5 percent) for the homozygous state.
Hepatic steatosis and steatohepatitis Hepatic steatosis and an
associated condition, non-alcoholic steatohepatitis (NASH), may
present solely with mild elevations of the serum aminotransferases,
which are usually less than fourfold elevated.
Muscle disorders Elevated serum aminotransferases, especially AST,
may be caused by disorders that affect organs other than the liver,
most commonly striated muscle.
Thyroid disorders Thyroid disorders can produce elevated
aminotransferases by unclear mechanisms.
Celiac disease Several reports have described elevated serum
aminotransferases in patients with undiagnosed celiac disease.
Adrenal insufficiency Aminotransferase elevation (1.5 to 3 times the
upper limit of normal) has been described in patients with adrenal
insufficiency (due to Addison's disease or secondary causes),
including those without obvious clinical features of the disorder.
Autoimmune hepatitis Autoimmune hepatitis (AIH) is a condition found
primarily in young to middle-aged women. The diagnosis is based upon
the presence of elevated serum aminotransferases, the absence of other
causes of chronic hepatitis, and features (serological and
pathological) suggestive of AIH.
Wilson's disease Wilson's disease, a genetic disorder of biliary
copper excretion, may cause elevated aminotransferases in asymptomatic
Alpha-1-antitrypsin deficiency Alpha-1-antitrypsin deficiency is an
uncommon cause of chronic liver disease in adults."
You may want to read further articles discussing elevated liver
enzymes I have written at Med Help International:
Here are some considerations for workup. I would first repeat the
liver tests - they are only mildly elevated. Make sure the results
aren't the cause of lab error.
If the liver enzymes continue to be elevated, then here is a
recommended approach for evaluation. Any medication can elevate liver
enzymes - make sure that any medications you are taking is not the
culprit. If you drink alcohol, I would abstain and then repeat the
enzymes in a few months. Alcohol can transiently elevate liver
enzymes. An ultrasound to evaluate the liver is also recommended.
This can determine if any anatomical abnormalities such as a mass or
conditions such as fatty liver is the cause. Tests for hepatitis
should also be routinely ordered.
If those tests are all negative, then further testing for
hemochromatosis (iron, iron binding capacity, ferritin) may be
considered. If every test continues to be negative, then a liver
biopsy may be considered if the enzymes are persistantly two-fold
above normal. This would be the definitive diagnostic test.
Regarding the rectal bleeding, there are several causes as well.
Hemorrhoids would be the most common cause in someone in your age
group. Other causes include polyps, colorectal cancer,
diverticulosis, or inflammatory bowel disease. A colonoscopy is a
wise next step.
