Infrequent bowel movements, hard stools, or difficulty passing stool. Review possible causes, self-care and warning signs that need medical attention.
About Constipation
Infrequent bowel movements, hard stools, or difficulty passing stool
Urgency category: normal. Common clinician to consult: General Physician or Gastroenterologist.
Constipation can mean passing stools less often than is usual for you, having hard or lumpy stools, straining, or feeling that your bowel has not emptied. Fewer than three bowel movements a week is one common clinical description, but a change from your usual pattern and how you feel also matter.
Common contributors include changes in food or fluid intake, low dietary fibre, reduced activity, pregnancy, some medicines, and health conditions. A clinician may ask about bowel habits, medicines, diet, and other symptoms before deciding whether tests or treatment are needed.
For mild constipation without warning signs, gradual changes to fibre intake, fluids if you have not been told to restrict them, movement, and a regular unhurried toilet routine may help. Persistent or recurrent symptoms deserve clinical advice; do not stop prescribed medicines or start laxatives without checking what is suitable for you.

How to interpret this symptom
Digestive symptoms can reflect diet, infection, medicines, inflammation, stress or another cause. Pattern, duration, hydration and warning signs help determine urgency.
A clinician may ask about pain, bowel habits, vomiting, blood, weight change, diet, medicines and exposures. Examination and stool, blood or imaging tests may be selected.
When constipation may need urgent attention
This symptom is generally suitable for non-emergency review, but severity and associated symptoms can change urgency. Seek urgent care for vomiting blood, black stool, severe or worsening abdominal pain, persistent vomiting, marked swelling, inability to keep fluids down, dehydration, high fever, confusion or severe weakness.
Possible causes
- Low fibre intake or a recent change in diet or routine
- Not drinking enough fluid, unless fluid intake is medically restricted
- Low physical activity or ignoring the urge to have a bowel movement
- Medicines such as opioid pain medicines or some other prescribed drugs
- Pregnancy, irritable bowel syndrome, or another health condition
Self-care
- Increase fibre gradually through foods such as vegetables, fruit, pulses, and whole grains; increase more slowly if it worsens bloating.
- Drink fluids regularly unless a clinician has advised a fluid restriction.
- Stay physically active within your abilities and usual medical advice.
- Allow unhurried toilet time and respond when you feel the urge; a footstool may make positioning more comfortable.
- Ask a pharmacist or clinician before using a laxative, fibre supplement, or changing a prescribed medicine.
Self-care limits
Hydration, gentle eating and avoiding irritants may help mild symptoms. Do not keep using home remedies when pain is severe, blood is present, dehydration is developing or symptoms persist.
When to seek medical help
- Seek urgent medical care for severe or worsening abdominal pain, repeated vomiting, a swollen abdomen, or inability to pass stool or gas.
- Contact a clinician promptly for blood in the stool, black stool, unexplained weight loss, persistent fatigue, or a new ongoing change in bowel habits.
- Arrange medical advice if constipation keeps recurring, does not improve with reasonable self-care, or may be related to a medicine.
- Seek advice earlier for a child, an older or frail person, pregnancy, or a person with significant long-term illness.
Preparing for a consultation
- Bowel or vomiting pattern and any blood or color change.
- Foods, medicines, travel or exposures that precede symptoms.
- Hydration, fever, pain location and weight change.
- Current medicines and previous digestive tests.

When should I contact a clinician?
Ask for medical advice if constipation persists, repeatedly returns, changes suddenly, affects daily life, or may be related to a medicine. Seek advice sooner for a child, pregnancy, an older or frail person, or significant long-term illness.
Should I take a laxative or stop a medicine?
