Natural remedies for diarrhoea

Diarrhoea is characterised by the emission of soft to liquid stools, more frequent than usual. This abnormal transit may be accompanied by bloating, intestinal gas, headaches and abdominal cramps of varying intensity.

It indicates a lack of water reabsorption in the large intestine (or colon): the water is then evacuated with the stools, dissolving them. It can also signal an acceleration in transit, preventing the digestive process from running smoothly. These phenomena can have many causes.

Please note: Diarrhoea is considered acute if it lasts a few days at most, and chronic if it persists for more than a month.

Bacterial or viral infections such as gastroenteritis can lead to a proliferation of harmful bacteria in the intestines, upsetting the natural balance of intestinal flora.

Similarly, taking medicines, particularly antibiotics, designed to inhibit the growth of pathogenic bacteria during infections, can also affect the good bacteria present in the intestines. These good bacteria are essential for maintaining regular transit and ensuring healthy digestion. By altering this balance, antibiotics can cause digestive disorders such as diarrhoea and other intestinal problems.

Intense stress (such as before an exam or after an emotional shock) can affect the digestive system, causing diarrhoea due to the release of stress hormones such as cortisol and adrenaline, which can upset the digestive balance.

These parasites are generally transmitted by ingesting contaminated food or water. Amoebae and pinworms in particular can cause a variety of digestive problems, including diarrhoea, abdominal pain and bloating.

Although most cases of diarrhoea are benign, the main risk is dehydration. So when you have diarrhoea, you should regularly check for the following signs: weakness and irritability, thirst, frequent urination with dark urine, sunken eyes, feeling unwell, etc.

This is why we try to stop the phenomenon as quickly as possible, particularly in children, while at the same time providing water and nutrients to effectively rehydrate the body.

Once the water loss has been stemmed and the body has been rehydrated as it should be, the cause must not be overlooked, if it has been identified, and the intestinal flora must be rebalanced in the medium term.

Any very heavy diarrhoea associated with a high fever, significant weight loss, severe abdominal pain or even the presence of blood in the stools should prompt you to consult a doctor as soon as possible to determine the cause. If the diarrhoea lasts for more than a few days, you should also consult a doctor. A stool analysis (coproculture) and a blood test may then be prescribed, as well as a colonoscopy if necessary.

Please note: Diarrhoea in infants, elderly or during pregnancy is an emergency requiring immediate medical attention.

Psyllium: Psyllium has the property of absorbing excess water in the intestines, making it an invaluable aid against diarrhoea. Consume 1 to 3 tablespoons of blond psyllium a day in a large glass of water.

Purple Loosestrife: Astringent and intestinal antiseptic, this anti-diarrhoea plant can be taken as an infusion (flowering tops) at a rate of 30 grams per litre of water. Drink ½ litre a day. This plant is not recommended during pregnancy or while breastfeeding.

Bramble: Bramble's anti-viral and astringent properties make it a good anti-diarrhoea remedy in the form of infusions, 3 cups a day between meals. It is very mild, and one of its major advantages is that it can be used during pregnancy and by children.

Dried bilberry: A decoction of dried bilberry fruit has strong astringent properties. Use around 50 grams of dried fruit for a medium saucepan of cold water, bring to the boil and then leave to infuse over a low heat for 45 minutes.

Kefir: Kefir (made from water or fermented milk) contains several strains of beneficial bacteria, which help to regulate intestinal transit and restore microbiotic balance.

Plain yoghurt (unpasteurised): Yoghurt containing live cultures, such as Lactobacillus acidophilus, can help rebalance the intestinal flora and encourage the growth of good bacteria in the intestines, reducing the effects of diarrhoea.

Kimchi: This fermented Korean vegetable contains beneficial lactic acid bacteria, such as Lactobacillus plantarum, which promote intestinal health.

Pickles (fermented cucumber, onion and carrot): contain probiotics that help regenerate the intestinal flora after diarrhoea.

If the diarrhoea persists for more than 48 hours or if signs of dehydration appear, such as intense thirst or a feeling of weakness and dizziness, it is advisable to consult a health professional.

Finally, beware of self-medication. You should seek medical advice before taking any medication.
