The real cause for the connection between
diabetes and diarrhea is not clear, but from the result we have here on a research
suggests that neuropathy (which is a problem with the
peripheral nerves)or (Neuropathy refers to numbness
or pain resulting from nerve damage.) may be a factor. If you have diabetes,
high blood sugar levels can damage your nerve fibers. This generally occurs in
the hands or feet. Issues with neuropathy are common causes for many of the
complications that accompany diabetes in human.
Another possible cause is sorbitol (Sorbitol is a type
of carbohydrate called a sugar alcohol, or polyol. Sorbitol contains
about one-third fewer calories than sugar and is 60 percent as sweet. Sorbitol is also commercially produced and is the most commonly used polyol in
the U.S.). People often use this sweetener
in diabetic foods. Sorbitol has proven to be a potent laxative in amounts as
small as 10 grams.
So an imbalance in your enteric
nervous system (ENS) can also cause diarrhea. Your ENS regulates the functions
of your gastrointestinal system.
Researchers
have also looked at the following possibilities:
- bacterial overgrowth
- pancreatic exocrine insufficiency
- fecal incontinence resulting from anorectal dysfunction
- Celiac disease
- an inadequate breakdown of sugars in the small intestine
- pancreatic insufficiency
People with diabetes can also have
the same triggers for diarrhea as people without diabetes. These triggers can
include:
- coffee
- alcohol
- dairy
- fructose
- too much fiber
People with diabetes may, of course,
develop diarrhea for a variety of reasons, just like anyone else. Diarrhea is a
symptom of many diseases such as viral or bacterial infections, celiac disease,
irritable bowel syndrome, and Crohn's disease. It is a side effect of some
medications, such as metformin (Metformin is an oral
diabetes medicine that helps control blood sugar levels), and some
sugar-free sweeteners can cause diarrhea in some people.
However, diarrhea can also be a symptom of a type of autonomic neuropathy.
This is what is known as diabetic diarrhea. Although this condition is not
uncommon, the diagnosis is usually made only after a detailed history and
diagnostic tests reveal no other cause for the diarrhea
.
Unlike the more widely known peripheral sensory neuropathy, which affects
the hands and feet, autonomic neuropathy damages the nerves that control
involuntary activities of the body. More commonly known types of autonomic
neuropathy include erectile dysfunction and orthostatic (or postural)
hypotension, the feeling of light-headedness or dizziness you get from standing
after lying or sitting down.
Diabetic diarrhea occurs usually at night, is watery and painless, and can
be associated with fecal incontinence. Bouts of diarrhea can be episodic, along
with intermittently normal bowel habits or even alternating with periods of
constipation.
The treatment for diabetic diarrhea is individualized, but it generally starts with antidiarrheal agents such as Lomotil (a combination of diphenoxylate and atropine) or Imodium. High-fiber foods or bulk-forming laxatives such as Metamucil may help decrease the symptoms. As with all neuropathies, good glucose control is important in controlling the symptoms.

If bacterial overgrowth in the intestines is said to be present, antibiotics
may be ordered. Medications like clonidine or octreotide, which have other
primary uses but have been shown to help diarrhea, can be used in more advanced
cases that do not respond to other treatments.
