When you're plagued with this condition, finding out the causes of diarrhea becomes very important.
For most people, diarrhea (or diarrhoea as it's spelled in England) is of short duration, maybe just a day or two. For others, it's a habitual, chronic problem with seemingly no detectable cause.
For many of us, it strikes when we visit other parts of the world and it's then known as 'traveler's diarrhea'.
Diarrhea is not a disease in itself, but a symptom of some other underlying causes, most benign, some serious. It can exist alone or be accompanied by other symptoms as well.
Ordinarily, water is absorbed through the intestinal walls as food passes through the large intestine and fecal matter leaves the body as a solid mass. Two gallons/8 litres of water are reabsorbed every day from the colon and for this to occur, feces have to spend a certain amount of time there.
If something speeds up or otherwise interferes with this process, the fluids will be expelled from the body with fecal matter instead of being re-absorbed.
So one of the causes of diarrhea is when water is not re-absorbed in the intestine, resulting in frequent and loose, watery bowel movements.
But sometimes, other factors can cause the bowel to secrete more water. For example, bacteria such as E. coli and staphylococcus bring on diarrhea by stimulating water secretions, which explains why food- and water-borne infections commonly cause diarrhea. Some laxatives work the same way.
Apart from the loose stools, other symptoms that may accompany diarrhea include vomiting, cramping, thirst and abdominal pain. Some people may run a fever as well.
It's rarely a serious condition, except in infants, young children and the elderly, as dehydration can happen suddenly and be very dangerous.
Diarrhea causes the loss of both fluids and
electrolytes (minerals), which can make you feel disoriented and weak
and can affect your blood pressure, heart rate and muscle movement, so
it's essential to replace the lost fluids!
Many factors can cause a decrease in water absorption in the intestinal tract, or an increase in water secretion, or a combination of both.
Depending on the causes, diarrhea can be divided into four major types:
Osmotic diarrhea - when too much water is drawn into the bowels - can be the result of carbohydrate malabsorption (e.g. lactose intolerance); magnesium salts; and excessive vitamin C intake.
Secretory diarrhea - when there is an increase in the active secretion, or there is an inhibition of absorption - can be the result of toxin-producing bacteria; hormone-producing tumors; fat malabsorption (e.g. lack of bile output); laxative abuse; and surgical resection of small intestine.
Exudative diarrhea - with the presence of blood and pus in the stool - can be caused by inflammatory bowel disease (Chron's disease or ulcerative colitis); pseudo-membranous colitis (a post-antibiotic diarrhea caused by an overgrowth of the bacterium Clostridium difficile); and bacterial infection by other organisms.
is caused by inadequate contact between the intestinal walls and the
intestinal contents, leading to poor absorption and is the result of
surgical removal of sections of the intestine.
Most diarrhea is self-limiting. It's the body's way of getting rid of something disagreeable - food, microbes or toxins. So for acute diarrhea, just let it flow and keep drinking plenty of water and fluids.
Most diarrhea lasts only a day or two, but when it continues beyond a few days, it's very important to find the causes of diarrhea and not just try to stop the symptoms with medications.
If you suffer with chronic diarrhea, you are not getting the maximum benefit from the foods you eat, no matter how good they are, because you are not absorbing all the nutrients and this can have long term effects on your health.
If you want to find out what foods trigger your symptoms, you might want to try an Elimination Diet specific for people who experience diarrhea (either related to IBS or to other conditions).
Unquestionably, diet can bring on, aggravate or alleviate diarrhea.
If you suffer with diarrhea you want to make sure that the foods you eat are not aggravating your symptoms. On the contrary, by eating the right stuff, you can shorten by 1/3 to 1/2 the recovery time from a bout of diarrhea and even preventing it from occurring altogether.
