Diarrhea can have many reasons. The causes of diarrhea and how we can treat it.

The area of “normal stool” is pretty broad, and stool consistency and frequency can vary significantly between individuals. Passing stool between three times a day and every three days is completely normal.

What is diarrhea and what are the symptoms?

The main criteria for diarrhea are papescent or watery stool.

Usually more than three times a day.

The World Health Organization defines diarrhea as follows:

  • More than three stool evacuations a day
  • Papescent to liquid, watery stool
  • More than 250 grams of stool a day

There is a difference between acute and chronic diarrhea.

Acute diarrhea is normally caused by an infection. An acute illness often starts suddenly and can last up to two weeks. Often, acute diarrhea caused by infection is harmless. Uncomfortable side effects of acute diarrhea are mostly:

  • Pressure in the stomach area
  • Nausea
  • Stomach pains, stomach cramps

Longer periods of diarrhea are referred to as chronic diarrhea. In cases of diarrhea lasting for longer periods of time, you should consult your GP.

What causes diarrhea?

Diarrhea may be caused by various things. These include infections, as well as chronic infections and irritable colons. On the one hand, you may experience a dysfunctional intake of water and salt in the colon area. But it is also possible that diarrhea is caused by an increased distribution of water and salts into the gut lumen (secretion). It could also be the case that both mechanisms interact with each other, for example in case of an infection of the colon. In case of an irritable colon, changed movements of the colon (motility) could also cause diarrhea.

An overview of the most important causes of diarrhea:

  • Infections caused by bacteria, viruses and other germs or their toxins (poisons). The infection could, for example, be caused through droplet or smear infections or by consuming food, which has gone off
  • Food intolerances, such as lactose intolerance, fructose or sorbitol malabsorption, or coeliac disease
  • Irritable colon syndrome
  • Chronic infection of the colon, such as in case of Crohn’s disease, colitis ulcerosa or microscopic colitis
  • Medication, which has an effect on the colon, such as antibiotics, anti-depressants, ACE blockers, diuretics, painkillers such as NSAR and many more
  • Exocrine pancreatic insufficiency
  • Bacterial overgrowth in the small intestine
  • Psychological triggers, such as fear and stress
  • Tumors

What tips are there against diarrhea?

In order to avoid acute diarrhea illnesses, certain hygienic and behavioral rules should be followed. One of the most important measures is to wash your hands often! When travelling, it is advisable to avoid tab water and products created thereof, such as ice cubes and pressed fruit juices. You should peel fruit and vegetables or wash them thoroughly with germ-free water.

How can diarrhea be treated?

In principal, it is important to identify the case of the diarrhea and to treat it. Diarrhea is treated symptomatically. In case of the loss of a lot of body fluids, the body can become dangerously dehydrated, and it is important to act quickly.

Babies, infants and older people are especially at risk of dehydration caused by diarrhea.
Your pharmacy will offer various remedies in case of diarrhea, starting with fluid and electrolyte replacement products, and including products to rebuild the gut flora, products based on organic films to protect the infected intestinal mucosa, and motility inhibitors (inhibitors of colon movements).

  • Replacing fluids and electrolytes (= basic treatment in case of diarrhea)

    If the diarrhea has led to a lot of fluid having been lost in a short amount of time, these fluids and electrolytes will have to be replaced. There are a number of specific rehydration solutions available.

  • Cramp inhibitors & inhibitors of colon movements

    In case of strong stomach cramps, cramp-relieving remedies (spasmolysants) may provide relief. Sometimes, medication may be used, which inhibits colon movements, and which therefore reduces the number of stool evacuations.

  • Antibiotics

    Depending on the cause of the diarrhea, antibiotics may be used as a means of treatment. Whether this makes sense in specific cases – i.e. whether it is bacterial infection or not – shall be decided by the responsible physician.

  • Probiotics

    The administering of probiotics in the form of capsules, yoghurts, drinks etc. may shorten the duration of acute diarrhea (by about one day), but they are mainly used as a preventative remedy.
