Constipation

Constipation is when you have difficulty passing bowel movements (pooing) or less frequent bowel movements than normal.

Constipation is common in both adults and children.

The information in this article relates to constipation in adults and children over 12 years of age. If you are caring for a child with constipation, see Constipation in children.

Symptoms of constipation include:

• having trouble passing bowel movements
• having bowel movements less often than usual
• passing hard, lumpy stools (poo)
• straining (pushing hard) during bowel movements
• passing only small amounts of stool at a time
• feeling like you have not completely emptied your bowels after a bowel movement
• pain or discomfort in your stomach

Bowel movement frequency is different for everyone. For adults, normal bowel frequency ranges from 3 bowel movements per day to 1 bowel movement every 3 days.

If you don't have a bowel movement every day, that doesn't mean you are constipated.

Constipation can happen when your stool is hard and dry, making it difficult to have a normal bowel movement. This is usually caused by:

• not eating enough fibre
• having a high fat diet
• not drinking enough water
• not getting enough physical activity
• a change in daily routine
• being stressed or anxious

You can also become constipated if you:

• are pregnant (Opens in new tab)
• take certain medicines, such as strong pain-relief medicines or antidepressants
• have certain medical conditions, such as a thyroid problem, Parkinson's disease or diabetes
• have a problem with your digestive system, such as irritable bowel syndrome, bowel obstruction or diverticulitis

Constipation can also occur without any known cause.

Your doctor can diagnose constipation. Your doctor will ask about:

• your symptoms
• your normal bowel habits
• any medical conditions you have
• any medicines you are taking, including prescription, over-the-counter medicines and supplements

Your doctor might also examine you. This may include:

• feeling your abdomen (tummy)
• a digital rectal exam (gently examining your anus and bottom using a gloved finger)

Tests

Your doctor may recommend further tests if your constipation is severe or you have other symptoms.

Further tests your doctor might recommend include:

• blood tests
• an x-ray of your abdomen
• colonoscopy (a flexible tube with a camera on one end to examine the inside of your bowel)
• magnetic resonance imaging (MRI) of your abdomen

See your doctor if you:

• have severe constipation. This might mean 3 or more days between bowel movements, tummy pain, straining for a long period or feeling that there is a 'ball', blocking your rectum.
• have constipation that is not getting better with simple lifestyle changes
• are worried about your symptoms

You should also see your doctor if you have constipation and you:

• are over 50 years old
• have a family history of bowel cancer

When to seek urgent care

Get urgent care if you have constipation as well as:

• unexplained weight loss
• bleeding from your rectum (bottom) or blood in your stool
• severe abdominal (tummy) pain, cramping or bloating
• vomiting

Sometimes constipation can be a sign of a serious condition such as bowel obstruction or bowel cancer.

The treatment of constipation will depend on the cause.

Self-care at home

The following lifestyle measures can help you manage constipation at home:

• Eat more high-fibre foods, such as fruits and vegetables.
• Drink plenty of water and other fluids.
• Do regular physical activity.
• Use relaxation techniques to help manage stress or anxiety.

If these lifestyle measures don't work, ask your doctor or pharmacist for advice.

Medicines for constipation

Laxatives can be used to treat constipation. There are several different types. Ask your doctor or pharmacist which laxative may be best for you.

Being constipated can increase your chances of developing:

• haemorrhoids — swollen or inflamed veins in your anus and rectum
• anal fissures — small splits in your anus that cause pain and bleeding
• faecal impaction — when stool becomes stuck in your colon
• faecal incontinence — leaking of stool between bowel movements
• rectocele — a bulge in your rectal wall caused by excessive pushing over long periods of time
• megarectum and megacolon — when your colon and rectum become abnormally stretched

You can help prevent constipation by having good toilet habits. Here are some tips that can help:

• Always go to the toilet when you get the urge to do a poo — don't ignore it or wait until later.
• Don't go to the toilet 'just in case' — only go when you need to.
• Make sure that you use the correct sitting position when you're on the toilet. Sit on the toilet, place your elbows on your knees and lean forward.
• Support your feet with a footstool. This helps to fully relax your pelvic floor and muscles around your bottom.

Eat foods that are high in fibre to help prevent constipation, including:

• wholegrain bread
• cereals
• fruit
• vegetables
• nuts

Talk to your pharmacist about:

• using a fibre supplement to increase your fibre intake
• having your medicines reviewed, to see if they might be causing constipation
