Common Misdiagnoses and MSI-H colorectal cancer
Chronic digestive conditions often misdiagnosed: When diagnosing chronic symptoms
of the digestive tract, there are a variety of conditions that may be misdiagnosed.
The best known, irritable bowel syndrome, is over-diagnosed, whereas other
causes that are less known may be overlooked or misdiagnosed: celiac disease,
Crohn's disease, ulcerative colitis (both are called inflammatory bowel disease (IBD)),
diabetic gastroparesis, diabetic diarrhea.
Other possibilities include giardia, colon cancer, or other chronic infections.
Intestinal bacteria disorder may be hidden cause: One of the lesser known causes of diarrhea
is an imbalance of bacterial in the gut, sometimes called intestinal imbalance.
The digestive system contains a variety of "good" bacteria that aid digestion,
and they can decline for various reasons,
leading to digestive symptoms such as diarrhea.
The main treatment is to eat foods containing probiotics, typically yoghurt cultures.
See intestinal imbalance and probiotics.
Antibiotics often causes diarrhea: The use of antibiotics are very likely
to cause some level of diarrhea in patients.
The reason is that antibiotics kill off not only "bad" bacteria,
but can also kill the "good" bacteria in the gut.
This leads to "digestive imbalance" where there are too few remaining "good"
bacteria in the digestive system.
The treatment is typically to use "probiotics", such as by eating yoghurt cultures
containing more of the good bacteria.
See digestive imbalance and probiotics.
Food poisoning may actually be an infectious disease: Many people who come down
with "stomach symptoms" like diarrhea assume that it's "something I ate" (i.e. food poisoning).
In fact, it's more likely to be an infectious diarrheal illness (i.e. infectious diarrhea), that has been caught
from another person.
Such conditions may be transmitted via the fecal-oral route.
Alzheimer's disease over-diagnosed: The well-known disease of Alzheimer's disease
is often over-diagnosed.
Patients tend to assume that any memory loss or forgetulness symptom might be Alzheimer's,
whereas there are many other less severe possibilities.
Some level of memory decline is normal with aging,
and even a slight loss of acuity may be noticed in the 30's and 40's.
Other conditions can also lead a person to show greater forgetfulness.
For example, depression and depressive disorders can cause a person to
have reduced concentration and thereby poorer memory retention.
Dementia may be a drug interaction: A common scenario in aged care is for
a patient to show mental decline to dementia.
Whereas this can, of course, occur due to various medical conditions,
such as a stroke or Alzheimer's disease,
it can also occur from a side effect or interaction between multiple drugs
that the elderly patient may be taking.
There are also various other possible causes of dementia.
Mesenteric adenitis misdiagnosed as appendicitis in children: Because appendicitis is one of the
more feared conditions for a child with abdominal pain, it can be over-diagnosed
(it can, of course, also fail to be diagnosed with fatal effect).
One of the most common misdiagnosed is for children with mesenteric adenitis
to be misdiagnosed as appendicitis.
Fortunately, thus misdiagnosis is usually less serious than the reverse failure to diagnose appendicitis.
Tremor need not be Parkinson's disease: There is the tendency to believe that
any tremor symptom, or shakiness, means Parkinson's disease.
The reality is that there are various possibilities, such as benign essential tremor,
which is mostly harmless.
see the various causes of tremor and misdiagnosis of Parkinson's disease.
Spitz nevi misdiagnosed as dangerous melanoma skin cancer: One possible misdiagnosis to
consider in lieu of melanoma is spitz nevi.
See melanoma and spitz nevi.
Rare diseases misdiagnosed as Parkinson's disease: A rare genetic
disorder is often misdiagnosed as Parkinson's disease for men in their 50's.
The disease Fragile X disorder can show only mild symptoms in the early years,
and Parkinsons-like symptoms around age 50.
See misdiagnosis of Parkinson's disease.
Celiac disease often fails to be diagnosed cause of chronic digestive symptoms: One of the most common chronic digestive
conditions is celiac disease, a malabsorption disorder with a variety of symptoms (see symptoms of
celiac disease). A variety of other chronic digestive disorders tend to be diagnosed
rather than this condition.
See introduction to celiac disease or misdiagnosis of celiac disease.
Chronic digestive diseases hard to diagnose: There is an inherent
difficulty in diagnosing the various types of chronic digestive diseases.
Some of the better known possibilities are peptic ulcer, colon cancer, irritable bowel syndrome, or GERD.
Other sometimes overlooked possibilities include Crohn's disease, ulcerative colitis, chronic appendicitis,
Celiac disease, Carcinoid syndrome, gastroparesis, and others. See all types of chronic digestive diseases.

General Misdiagnosis Articles
Read these general articles with an overview of misdiagnosis issues.
When checking for a misdiagnosis of MSI-H colorectal cancer
or confirming a diagnosis of MSI-H colorectal cancer,
it is useful to consider what other
medical conditions might be possible misdiagnoses or other alternative
conditions relevant to diagnosis.
These alternate diagnoses of MSI-H colorectal cancer may already have
been considered by your doctor or may need to be considered as possible
alternative diagnoses or candidates for misdiagnosis of MSI-H colorectal cancer.
