Constipation is common, and it does not mean exactly the same thing for everyone.
This article is part of the AKK Knowledge Centre, our guide hub for Singapore gut health, Akkermansia and microbiome education.
HealthHub describes constipation as difficulty passing stool or a decrease in your normal frequency, often with:
- hard or dry stool,
- straining,
- bloating,
- incomplete emptying.
Normal bowel frequency can vary widely.
Some people go several times per day.
Others may go several times per week.
The important question is whether there has been a meaningful change from your normal pattern or whether passing stool has become difficult.
Key Takeaways
- Low fibre, low fluid intake and inactivity are common contributors.
- HealthHub advises increasing fibre-rich foods such as wholegrains, vegetables and fruit.
- HealthHub commonly advises around 6-8 glasses of fluid daily unless medically restricted.
- Regular movement can support bowel function.
- Do not routinely ignore the urge to pass stool.
- Toilet posture can make defecation easier.
- Some medicines and supplements can contribute to constipation.
- Persistent constipation or severe symptoms require medical assessment.
What Counts as Constipation?
Constipation may involve:
- hard stool,
- dry stool,
- straining,
- fewer bowel movements than usual,
- feeling incompletely emptied,
- abdominal discomfort.
Frequency alone is not enough.
Common Causes in Singapore Life
Low-Fibre Meals
A diet built mainly around:
- white rice,
- noodles,
- white bread,
- processed snacks
may contain less fibre than a diet with more vegetables and wholegrains.
Not Drinking Enough
Busy workdays and air-conditioned environments can make people forget to drink.
Sitting for Long Periods
Desk-bound jobs reduce daily movement.
Ignoring the Urge
Delaying bowel movements repeatedly can make stool harder to pass.
Routine Changes
Travel, shift work and irregular meals can affect bowel habits.
Medication or Supplements
HealthHub notes that some medicines and supplements — including iron or calcium in some cases — can contribute to constipation.
Never stop prescribed medication without discussing it with a healthcare professional.
Aim for More Fibre
HealthHub advises increasing fibre-rich foods such as wholegrains, vegetables and fruit, together with adequate fluid intake and regular physical activity.
Foods to include:
- brown rice,
- wholemeal bread,
- oats,
- vegetables,
- fruit,
- beans,
- lentils,
- nuts and seeds.
Increase gradually.
Fruit Choices
HealthHub’s adult constipation guidance mentions fruits such as:
- kiwi,
- prunes,
- dragon fruit
as options that may help bowel movement.
Fruit provides:
- fibre,
- water,
- plant compounds.
Drink Enough Fluid
HealthHub commonly recommends:
6–8 glasses, about 2 litres daily
unless your doctor advises otherwise.
You may need more during:
- heavy exercise,
- outdoor work,
- hot conditions.
But people on medical fluid restriction should follow their clinician’s plan.
Move Regularly
HealthHub recommends regular exercise as part of constipation prevention.
Movement can support:
- gastrointestinal motility,
- overall metabolic health,
- regular routines.
A daily walk is a reasonable starting point.
Do Not Ignore the Urge
Repeatedly delaying bowel movements can contribute to problems.
When possible:
- respond to the urge,
- allow enough time,
- avoid rushing.
Toilet Posture
HealthHub notes that posture can affect bowel function.
A practical position is:
- lean slightly forward,
- keep the back relatively straight,
- support the feet,
- keep knees above hip level if possible.
A small footstool can help some people.
What About Probiotic Foods?
HealthHub mentions foods such as:
- lower-sugar yoghurt,
- live-culture drinks,
- tempeh,
- kimchi.
These can be part of a varied diet.
But constipation should not be reduced to “not enough probiotics.”
Fibre, fluids, activity and medical causes matter, and rapid fibre changes can sometimes overlap with bloating after meals.
Should You Use a Laxative?
Different laxatives work in different ways.
Some are available from pharmacies.
But repeated constipation deserves assessment rather than indefinite self-treatment.
Ask a pharmacist or doctor which approach is appropriate.
When Should You See a Doctor?
HealthHub advises seeking medical review when constipation does not improve or causes significant discomfort.
Prompt evaluation is especially important with:
- severe pain,
- blood in stool,
- black stool,
- unexplained weight loss,
- vomiting,
- major change in bowel habits.
Constipation and Colorectal Screening
Constipation alone does not mean colorectal cancer.
But persistent changes in bowel habits are one reason medical evaluation can matter.
For average-risk Singaporeans aged 50 and above, Healthier SG Screening offers colorectal screening using FIT when eligible.
If symptoms are present, see a doctor rather than relying only on routine screening.
Frequently Asked Questions
Is it normal not to pass stool every day?
Yes. Normal frequency varies between individuals.
How much fibre should I aim for?
For constipation, HealthHub advises increasing fibre-rich foods such as wholegrains, vegetables and fruit, alongside fluids and regular physical activity.
How much water should I drink?
HealthHub commonly recommends 6–8 glasses daily for many adults unless medically restricted.
Can calcium supplements cause constipation?
Some supplements, including calcium and iron, can contribute in some people.
When is constipation serious?
Persistent symptoms, severe pain, bleeding, black stool, vomiting or unexplained weight loss require medical attention.
The Bottom Line
Constipation is often influenced by ordinary habits:
fibre, fluid, movement, toilet routine.
But it can also have medical causes.
If simple changes do not help, do not keep assuming it is only a “gut bacteria problem.”
