What Causes Diarrhea?

Definition, Prevalence, Causes and Treatment

Loose bowel motions or Diarrhea happens when semi-digested food is eliminated from the body too soon for nutrients to be absorbed. This can be because of missing enzymes or absent intestinal cell structures - typical damage caused by food toxins.


What is the definition of Diarrhea?

Definition of Diarrhea

According to the World Health Organisation diarrhea is:

  • 'having three or more loose bowel movements per day'

Diarrhea - is a troublesome and distressing gastro-intestinal symptom - and it happens for two main reasons:

  1. When the intestine's function is impaired
  2. When certain enzymes are missing

Both types come about as a consequence of trying to process food toxins - previously known as food intolerance.

Other symptoms associated with diarrhea include:

    • Stomach bloating, pain and flatulence
    • Dehydration and nutrient deficiencies
    • Depression or anxiety
    • Chronic fatigue or lethargy
    • Leaky Gut Syndrome - and its consequences

How do food toxins cause diarrhea?

How Food toxins cause diarrhea

One reason for diarrhea is an immune response to the toxins in some foods. Food toxins are often unrecognised or 'foreign' protein fragments. When the immune system senses these 'foreigners' it responds by putting itself 'on alert'. The immune response is to create inflammation, tissue damage and disruption to normal processes - in this case in the intestine.

Another reason diarrhea happens is when the intestine is unable to produce enzymes to digest certain sugars. E.g Lactose - (a sugar) needs Lactase (an enzyme) to break it down. If there is no Lactase present the sugar causes an 'osmotic purge' in the intestine. Too much fluid flows back into the waste products making stools loose and watery.


How do you treat Diarrhea?

Treatment for Diarrhea

Temporary relief treatment: Your doctor may prescribe medications or supplements for temporary relief - and/or other tests and treatments. Some people choose to use probiotics thinking that will help.  Unfortunately many contain ingredients which actually cause diarrhea.

Permanent Cure: Cheronic diarrhea is a Red Flag - a precious warning signal. Many find a low toxin diet works wonders. 


'I've had so many tests in the past that say "normal" or whatever, according to their criteria, and it was when I started reading about food intolerances etc that some light was shed on the possible real cause.  I'm mainly referring to my diarrhea here - 10 years of suffering, endless tests saying "normal" and then a finally a solution that turned out to be a (food intolerance) problem, and relief coming within days by simply eliminating some foods from my diet. You'll have to forgive me - I've become a bit of a major "Food Intolerance Convert" after years and years of no answers from the medical profession.  Your website really opened my eyes.  Sorry if I think you have all the answers - it's a big compliment from me - sincerely. Keep up the great work.  Kindest regards - Jane'
