For most people, the daily or near-daily ritual of having a bowel motion is not something we give a great deal of thought to. But for some people, the need to do a “number two” in a public toilet or at work can be beset with significant stress and anxiety.

In recognition of the discomfort people may feel around passing a bowel motion at work, the Queensland Department of Health recently launched a social media campaign with the message “It’s okay to poo at work”.

The campaign has gained significant traction on Instagram and Facebook. It has been praised by health and marketing experts for its humorous handling of a taboo topic.

A colourful Instagram post is accompanied by a caption warning of the health risks of “holding it in”, including haemorrhoids and other gastrointestinal problems. The caption also notes:

If you find it extremely difficult to poo around other people, you might have parcopresis.

What is parcopresis?

Parcopresis, sometimes called “shy bowel”, occurs when people experience a difficulty or inability to poo in public toilets due to fear of perceived scrutiny by others.

People with parcopresis may find it difficult to go to the toilet in public places such as shopping centres, restaurants, at work or at school, or even at home when friends or family are around.

They may fear being judged by others about unpleasant smells or sounds when they have a bowel motion, or how long they take to go, for example.

Living with a gastrointestinal condition (at least four in ten Australians do) may contribute to parcopresis due to anxiety about the need to use a toilet frequently, and perceived judgment from others when doing so. Other factors, such as past negative experiences or accessibility challenges, may also play a role.

For sufferers, anxiety can present in the form of a faster heart rate, rapid breathing, sweating, muscle tension, blushing, nausea, trembling, or a combination of these symptoms. They may experience ongoing worry about situations where they may need to use a public toilet.

Living with parcopresis can affect multiple domains of life and quality of life overall. For example, sufferers may have difficulties relating to employment, relationships and social life. They might avoid travelling or attending certain events because of their symptoms.

How common is parcopresis?

We don’t really know how common parcopresis is, partly due to the difficulty of evaluating this behaviour. It’s not necessarily easy or appropriate to follow people around to track whether they use or avoid public toilets (and their reasons if they do). Also, observing individual bathroom activities may alter the person’s behaviour.

I conducted a study to try to better understand how common parcopresis is. The study involved 714 university students. I asked participants to respond to a series of vignettes, or scenarios.

In each vignette participants were advised they were at a local shopping centre and they needed to have a bowel motion. In the vignettes, the bathrooms (which had been recently cleaned) had configurations of either two or three toilet stalls. Each vignette differed by the configuration of stalls available.

The rate of avoidance was just over 14% overall. But participants were more likely to avoid using the toilet when the other stalls were occupied.

Around 10% avoided going when all toilets were available. This rose to around 25% when only the middle of three toilets was available. Men were significantly less likely to avoid going than women across all vignettes.

For those who avoided the toilet, many either said they would go home to poo, use an available disabled toilet, or come back when the bathroom was empty.

Parcopresis at work

In occupational settings, the rates of anxiety about using shared bathrooms may well be higher for a few reasons.

For example, people may feel more self-conscious about their bodily functions being heard or noticed by colleagues, compared to strangers in a public toilet.

People may also experience guilt, shame and fear about being judged by colleagues or supervisors if they need to make extended or frequent visits to the bathroom. This may particularly apply to people with a gastrointestinal condition.

Reducing restroom anxiety

Using a public toilet can understandably cause some anxiety or be unpleasant. But for a small minority of people it can be a real problem, causing severe distress and affecting their ability to engage in activities of daily living.

If doing a poo in a toilet at work or another public setting causes you anxiety, be kind to yourself. A number of strategies might help:

• identify and challenge negative thoughts about using public toilets and remind yourself that using the bathroom is normal, and that most people are not paying attention to others in the toilets
• try to manage stress through relaxation techniques such as deep breathing and progressive muscle relaxation, which involves tensing and relaxing different muscles around the body
• engaging in gradual exposure can be helpful, which means visiting public toilets at different times and locations, so you can develop greater confidence in using them
• use grounding or distraction techniques while going to the toilet. These might include listening to music, watching something on your phone, or focusing on your breathing.

If you feel parcopresis is having a significant impact on your life, talk to your GP or a psychologist who can help identify appropriate approaches to treatment. This might include cognitive behavioural therapy.

Many people are drinking less sugary soft drink than in the past. This is a great win for public health, given the recognised risks of diets high in sugar-sweetened drinks.

But over time, intake of diet soft drinks has grown. In fact, it’s so high that these products are now regularly detected in wastewater.

So what does the research say about how your health is affected in the long term if you drink them often?

What makes diet soft drinks sweet?

The World Health Organization (WHO) advises people “reduce their daily intake of free sugars to less than 10% of their total energy intake. A further reduction to below 5% or roughly 25 grams (six teaspoons) per day would provide additional health benefits.”

But most regular soft drinks contain a lot of sugar. A regular 335 millilitre can of original Coca-Cola contains at least seven teaspoons of added sugar.

Diet soft drinks are designed to taste similar to regular soft drinks but without the sugar. Instead of sugar, diet soft drinks contain artificial or natural sweeteners. The artificial sweeteners include aspartame, saccharin and sucralose. The natural sweeteners include stevia and monk fruit extract, which come from plant sources.

Many artificial sweeteners are much sweeter than sugar so less is needed to provide the same burst of sweetness.

Diet soft drinks are marketed as healthier alternatives to regular soft drinks, particularly for people who want to reduce their sugar intake or manage their weight.

But while surveys of Australian adults and adolescents show most people understand the benefits of reducing their sugar intake, they often aren’t as aware about how diet drinks may affect health more broadly.

What does the research say about aspartame?

The artificial sweeteners in soft drinks are considered safe for consumption by food authorities, including in the US and Australia. However, some researchers have raised concern about the long-term risks of consumption.

People who drink diet soft drinks regularly and often are more likely to develop certain metabolic conditions (such as diabetes and heart disease) than those who don’t drink diet soft drinks.

The link was found even after accounting for other dietary and lifestyle factors (such as physical activity).

In 2023, the WHO announced reports had found aspartame – the main sweetener used in diet soft drinks – was “possibly carcinogenic to humans” (carcinogenic means cancer-causing).

Importantly though, the report noted there is not enough current scientific evidence to be truly confident aspartame may increase the risk of cancer and emphasised it’s safe to consume occasionally.

Will diet soft drinks help manage weight?

Despite the word “diet” in the name, diet soft drinks are not strongly linked with weight management.

In 2022, the WHO conducted a systematic review (where researchers look at all available evidence on a topic) on whether the use of artificial sweeteners is beneficial for weight management.

Overall, the randomised controlled trials they looked at suggested slightly more weight loss in people who used artificial sweeteners.

But the observational studies (where no intervention occurs and participants are monitored over time) found people who consume high amounts of artificial sweeteners tended to have an increased risk of higher body mass index and a 76% increased likelihood of having obesity.

In other words, artificial sweeteners may not directly help manage weight over the long term. This resulted in the WHO advising artificial sweeteners should not be used to manage weight.

Studies in animals have suggested consuming high levels of artificial sweeteners can signal to the brain it is being starved of fuel, which can lead to more eating. However, the evidence for this happening in humans is still unproven.

What about inflammation and dental issues?

There is some early evidence artificial sweeteners may irritate the lining of the digestive system, causing inflammation and increasing the likelihood of diarrhoea, constipation, bloating and other symptoms often associated with irritable bowel syndrome. However, this study noted more research is needed.

High amounts of diet soft drinks have also been linked with liver disease, which is based on inflammation.

The consumption of diet soft drinks is also associated with dental erosion.

Many soft drinks contain phosphoric and citric acid, which can damage your tooth enamel and contribute to dental erosion.

Moderation is key

As with many aspects of nutrition, moderation is key with diet soft drinks.

Drinking diet soft drinks occasionally is unlikely to harm your health, but frequent or excessive intake may increase health risks in the longer term.

Plain water, infused water, sparkling water, herbal teas or milks remain the best options for hydration.
