What is chronic diarrhoea?

Chronic diarrhoea is the passing of loose, watery stools 3 or more times a day for 4 weeks or more. The condition can take a toll on your physical health, but can also impact your mental and emotional wellbeing. 

It’s normal to have diarrhoea from time to time, which might be caused by something like the flu or food poisoning. But diarrhoea that’s frequent and persistent should be investigated by a specialist gastroenterologist.

At Welbeck, our consultants diagnose and treat patients with chronic diarrhoea in our state-of-the-art Digestive Health Centre.

What are the symptoms of chronic diarrhoea?

When functioning as it should, your colon receives liquid food waste from your small intestine and condenses it into solid poo. If you’re experiencing diarrhoea, this indicates that something is going wrong with this process. 

Our gastroenterologists are experienced in both the diagnosis of chronic diarrhoea and identifying its cause. We recommend making an appointment to see one of our consultants if you’re experiencing diarrhoea and any of the following symptoms:

  • loose, watery stools more than 3 times a day 
  • frequent diarrhoea most days for 4 weeks or more
  • unintentional weight loss
  • abdominal pain
  • rectal bleeding
  • fever
  • weakness or fatigue

What causes chronic diarrhoea?

There are many possible causes of chronic diarrhoea, some of which you may be able to identify yourself, while others require the expertise of a specialist to determine.

Possible causes of diarrhoea include:

Diet

Certain foods and drinks, such as coffee, alcohol, and certain sugars, can affect the speed at which your food is digested, making it leave your body more quickly than it should, in the form of diarrhoea.

Intolerances, such as lactose or gluten intolerance, can also mean that certain foods are not digested and absorbed as well as they should be, also resulting in diarrhoea.

Certain medications and supplements

Some medicines, supplements, and even high doses of some vitamins and minerals can cause both short- and long-term diarrhoea. These include:

  • nonsteroidal anti-inflammatory drugs (NSAIDs), like aspirin and ibuprofen
  • proton pump inhibitors (PPIs)
  • some antibiotics
  • certain herbal supplements, like senna
  • high doses of vitamin C and magnesium
  • antacids that contain magnesium
  • some antidepressants
  • beta-blockers
  • metformin
  • chemotherapy
  • laxatives, when overused

Medical conditions

Chronic diarrhoea is also associated with a range of gastrointestinal conditions, including:

Medical treatments and surgeries

In some cases, chronic diarrhoea can come about as a result of a previous surgery, such as:

  • gastrectomy
  • gastric bypass
  • jejuno-ileal bypass
  • extensive resection of the ileum and right colon
  • minor resection of the terminal ileum
  • cholecystectomy

How is chronic diarrhoea diagnosed?

In most cases, our gastroenterologists will make a diagnosis of chronic diarrhoea based on your symptoms and how long you’ve had them for.

Sometimes, how your symptoms present and your medical and lifestyle factors can give your consultant a good indication of what’s causing your condition.

However, they may need to run some tests to either confirm their theory or to identify a less clear cause. Tests can include:

How to prevent chronic diarrhoea

If your diarrhoea is caused by certain foods or drinks, or an intolerance, cutting these out or making swaps, like changing your dairy milk for oat milk or regular pasta for gluten-free, may be enough to reduce your symptoms and help avoid bouts of long-term diarrhoea. 

If a medication is causing the problem, your consultant may be able to recommend a different type of drug, or can prescribe another medicine to help combat the side effects and prevent diarrhoea.

What are the risks of chronic diarrhoea?

Living with chronic diarrhoea can impact your quality of life, and for some people, it can lead to anxiety and depression, especially if it’s not addressed or effectively treated. 

Physically, chronic diarrhoea puts you at risk of dehydration and low electrolyte levels. This can stress your body and affect the health of your kidneys, heart, lungs, brain and nervous system.

If you’ve had diarrhoea 3 or more times a day for the last 4 weeks or more, get in touch to book a next- or same-day appointment with one of our gastroenterologists.

What are the treatment options for chronic diarrhoea?

How chronic diarrhoea is treated very much depends on the underlying cause. As mentioned, if your condition is related to foods, intolerance or a medicine, these can be identified and swapped or avoided to reduce symptoms and the instances of diarrhoea. 

If your chronic diarrhoea is caused by an underlying condition, this will need to be treated by a specialist. Doing so will likely improve your symptoms, and in some cases, can stop the issue altogether.

FAQs

Is morning diarrhoea normal?

Occasional diarrhoea upon waking is generally considered normal and in many cases isn’t a cause for concern. However, if you have morning diarrhoea frequently or persistently, we recommend making an appointment with a specialist.

Can anxiety cause diarrhoea?

Yes, anxiety is a common cause of diarrhoea for many people. The connection between the brain and the gut (the gut-brain axis) means that stress and anxiety can trigger physical symptoms, including diarrhoea.

What foods trigger chronic diarrhoea?

Some foods can certainly trigger an episode of diarrhoea. Some of the most common are: 

  • Dairy foods like cheese, milk and yoghurt (lactose intolerance)
  • Foods that contain gluten, like bread and pasta (coeliac disease or non-celiac gluten sensitivity)
  • Fatty or fried foods
  • Spicy foods
  • Foods containing artificial sweeteners (sorbitol, mannitol, xylitol)
  • FODMAP foods, including onions, garlic, beans, and apples
