The majority of the time, diarrhoea is brought on by a virus or bacterium that your body is attempting to eliminate. However, consuming certain foods might also cause a case of diarrhoea.

Digestion-inducing meals vary from person to person, but frequent offenders include dairy, spicy foods, and several vegetable groupings.

The best cures, when to consult a doctor, and 10 foods that often cause diarrhoea are all covered in this article.

Why do certain meals make you dizzy?

Everybody has a different trigger meal for diarrhoea. When you consume a food that you are intolerant to, you may get diarrhoea or loose stools.

Food intolerances to dairy and gluten are both frequent.

Chronic diarrhoea is often brought on by food intolerances. Other signs of food intolerance include gas, bloating, and stomach discomfort or cramps.

A food allergy is distinct from food intolerance. Along with hives, itchy skin, congestion, and tightness in the throat, food allergies may also result in diarrhoea.

Diarrhoea may also be caused by malnutrition. The small intestine's capacity to absorb nutrients from meals is decreased at this time. Malabsorption may result from certain dietary intolerances.

Nevertheless, even in persons who do not have food intolerances, certain meals might produce diarrhoea.

These are often foods that have high levels of artificial chemicals, oils, spices, or colonic stimulants.

1. Spicy cuisine

One of the most frequent causes of food-induced diarrhoea is spicy meals. Strong spices that your body isn't used to eating are particularly likely to cause this.

Common offenders include curry powders and chilli peppers. The heat of chilli peppers is caused by a compound called capsaicin.

According to research, capsaicin is both a severe irritant and may provide a number of 1therapeutic advantages, including the treatment of pain and arthritis. During digestion, capsaicin may irritate the lining of the stomach.

Large doses of capsaicin may result in the following side effects:

  • nausea
  • vomiting
  • abdomen ache
  • unpleasant diarrhoea

Try giving your dish a kick by adding spices that don't contain capsaicin, such as mustard powder or ground paprika, if consuming spicy foods is giving you diarrhoea. They often affect the stomach more subtly.

2. Sugar alternatives

Artificial sweeteners like aspartame, saccharin, and sucralose, as well as sugar alcohols, are examples of sugar replacements (e.g., mannitol, sorbitol, and xylitol).

The digestive tract might get irritated by several sugar alternatives. In fact, the possible laxative impact of some of the foods they are in is warned about on the label.

Particularly eating or consuming sugar alcohols may have a laxative effect, resulting in diarrhoea and flatulence.

Try reducing your intake if you believe sugar alternatives are contributing to diarrhoea. Typical meals that incorporate artificial sweeteners are:

  •  gum chewing
  • pastries and candies without sugar
  • healthy sodas
  • extra diet beverages
  • sugar-free cereals
  • Low-sugar condiments, such as ketchup and coffee creamer
  • a few mouthwashes and toothpaste

3. Dairy items such as milk

You may have lactose intolerance if you have loose stools after consuming milk or other dairy products.

Many individuals who are lactose intolerant are unaware of it. It might manifest later in life and often runs in families.

The inability of your body's enzymes to break down certain dairy sugars is known as lactose intolerance.

Your body rapidly eliminates these sugars rather than breaking them down, sometimes via diarrhoea.

There are several alternatives to cow's milk available on the market, including:

  • non-lactose dairy milk
  • Acorn milk
  • nuts milk
  • nut milk
  • coconut milk

4. Espresso

Coffee contains caffeine, which is a stimulant. It stimulates your digestive system and gives you a feeling of mental alertness. Many individuals immediately after drinking coffee experience bowel movements.

Drinking 2-3 cups of coffee or tea each day, according to the International Foundation for Gastrointestinal Disorders (IFFGD), may often result in diarrhoea.

In order to boost the laxative effects of their coffee, many individuals additionally add other digestive stimulants, such as milk, sugar alternatives, or creamers.

Due to additional compounds in coffee, even decaffeinated coffee might stimulate the stomach in certain individuals.

Coffee may have a laxative impact, but using dairy alternatives like oat milk or coconut creamer can lessen that effect.

Otherwise, try switching to green tea or another hot beverage if you believe coffee is the cause of your diarrhoea.

5. Caffeine-containing foods

In addition to coffee, several meals and beverages with caffeine might result in loose stools or diarrhoea.

Any product with a chocolate taste that contains caffeine by nature may also include caffeine in other forms.

Caffeine is often found in the following foods and beverages:

  • Coke and other soft drinks
  • stout tea
  • emerald tea
  • energy beverages
  • warm cocoa
  • chocolate and items with a chocolate taste

7. Glucose

Fruit contains fructose, a kind of natural sugar. When consumed in excess, fructose may cause constipation.

Because eating a lot of fruit involves consuming a lot of fructose, it might result in diarrhoea.

Added sources of fructose include:

  • candies
  • soft beverages
  • preservatives

In the summer, when fresh produce is more widely accessible, some individuals report having looser bowel movements.

7. Onions with garlic

Both garlic and onions contain fluids that might cause your intestines to become uncomfortable and emit gases when your stomach's acid breaks them down.

Onions and garlic contain fructans, a kind of carbohydrate that the body has a hard time breaking down.

They also include insoluble fibre, which facilitates rapid digestion of certain meals.

They include a lot of FODMAPs, a class of carbohydrates that may make some people throw up.

Another high-FODMAP item that might induce diarrhoea is a sugar alcohol, which was previously covered in this article.

If you wish to substitute celery or fennel for garlic and onions in your diet, give it a try.

These may provide a comparable flavour to your dish while posing a lower gastrointestinal (GI) risk.

8. Cauliflower with broccoli

Among the cruciferous veggies are broccoli and cauliflower. They are abundant in vitamins, minerals, and vegetable fibre.

Although the digestive system may have difficulty digesting certain veggies, they do provide several health advantages.

Big servings of fibre might cause constipation, gas, or diarrhoea if you're not accustomed to consuming a lot of them.

Consider beginning with modest servings and gradually increasing your fibre intake.

Diarrhoea may be lessened with a high-fibre diet, which is also good for your heart and digestive system.

9. Alcohol

Alcohol consumption might cause loose stools the next day. This is particularly valid while consuming wine or beer.

See if the diarrhoea stops by trying to cut down on alcohol. If it happens, you may want to cut down on your alcohol consumption to ease any gastrointestinal pain.

Whenever to see a doctor

It may be beneficial to contact a doctor if you have regular or persistent diarrhoea. They may assist you in determining if it's connected to a food intolerance or a condition of the digestive system.

Irritable bowel syndrome or another treatable digestive problem may be the cause of persistent diarrhoea.

If you see any of the following, see a doctor:

  • chronic or persistent diarrhoea
  • severe cramping or discomfort in the abdomen
  • severe signs of dehydration
  • blood or pus-filled stools

An elimination diet may be helpful if you are unsure of what foods are causing diarrhoea or other digestive issues.

To do this, you cut out certain meals and watch to see whether your symptoms go better. This enables you to determine how various meals are impacting your body.


Many everyday meals may make you sick. This can be due to a dietary intolerance or digestive system irritation caused by the meal.

Spicy meals, fried or oily foods, dairy products, and sugar alternatives are typical dietary items that induce diarrhoea.

If you think a certain meal is causing your diarrhoea, try cutting it out of your diet and see if your digestive problems improve.
