Constipation
Home > Patient Information > Information Links > Constipation
Constipation occurs when the bowel motions become harder or drier than usual. And therefore become more
difficult to pass. It could be a sign of an illness e.g. bowel
disease or be caused by some Medications.
Constipation worsens when there is inadequate bre in
your diet, insufficient fluid intake, lack of exercise and any
changes in your lifestyle e.g. lack of mobility. It should not
be regarded as a normal consequence of age.
The following simple steps should help.
Following the subsequent 6 Step plan should assist in the prevention and treatment of constipation.
It is important to give each step adequate time to work.
STEP 1
It is important to have a balanced diet, that is sufficient
fibre, fluid (8 glasses of water per day; [tea and coffee
should not be counted in the 8 glasses]), and most
importantly a balanced lifestyle.
You should have regular exercise (walking, swimming etc).
T his should be a comfortable level of exercise and take
into account any other medical conditions.
Allow 2 to 4 weeks for this to work.
In the majority of patients this wi11 be stifficient to return bowel function o normal. If this fails then move to step 2.
STEP 2
Bulk Forming Agents
Like fibre, these agents increase the bulk in the bowel,
which stimulates bowel muscle movement. Always drink
a full glass of water with each dose. In most cases it is
advisable to start at half to a third of the recommended
dose and gradually increase the dose to the
recommended level over three weeks. This is because the
sudden introduction of recommended doses can cause
abdominal discomfort in some people.
Allow 7 days for this to begin to work after the
recommended dose has been reached.
Examples of bulking agents include:
Physllium (Metamucil, Angiofibe, Apple fibre chewable
complex) or Physllium husks; Stercullia (Granucol,
Normacol Plus); Ispaghula husks (Fybogel); Crude fibre
(Fibyrax Extra, Fibyrax Fibre Trim, Guarina); Methycellulose
(Cellutone).
STEP 3
Stool Softeners
These agents soften bowel motions by increasing the
amount of lubrication and fluid secreted into the bowel.
These are best used when a hard stool mass is present or
to prevent excessive straining.
Allow 7 days for these to work.
Examples include: Docusate Sodium (Coloxyl)
STEP 4
Osmotic Laxatives
These agents draw fluid into the large bowel, with the
resulting bulk stimulating bowel movement.
Allow 2-3 days for these to work.
Examples include:
Sorbilol 70% (sorbilax), lactulose (Duphalac,
Actilax), Magnesium Salts (Epsom salts).
STEP 5
Stimulants
These agents stimulate gut movement via a direct irritant
effect. Sometimes, they can cause abdominal cramps.
Prolonged use is not recommended as it can lead to a
permanent non-functioning colon (melanosis coli).
Stimulants then have a limited role in the treatment of
chronic constipation.
Allow 12 hours for these to work.
Avoid their use in children
Examples include:
Biscody (Durolax, Bisalax); senna (Seokot,
Coloxyl and Senna, Nulax, Bioglan, Prune and
Senna, Laxettes with Senna, Bekunis, Agiolax
and some laxatives teas): Phenolpthalien
(Atophen, Agarol. Figsen, Laxettes, Ap-la-day):
Liquid Paraffin (Parachoc): Castor oil.
STEP 6
Suppositories and Enemas
These agents act locally by various methods to promote
evacuation.
Allow up to 1 hour for these to work.
NB these agents should not be used Routinely but
Reserved for acute situations.
Examples include:
Bisacodyl (durolax); coffibiflallor) producis
(microlax. Travad); giycerirr. Vocu&ale sodiufti.
Dehydration or an inadequate fluid intake can cause
constipation. Unless otherwise directed, you should drink
6-8 glasses of water per day to maintain kidney function
and bowel regularity.
Caffeine has a diuretic effect, causing an increased urine output and a loss of body fluid. Cups of tea and coffee
cannot be counted as part of your fluid intake.
A Stepwise Guide
Fibre: absorbs water like a sponge. This increases the bulk of the; faeces, making it softer and easier to pass. It is this bulk which stimulates the bowel muscle to work properly.
Therefore you need to have plenty of water and fluid.
Caffeine has a diuretic effect, causing an increased urine
output and a loss of body fluid. Cups of tea and coffee
cannot be counted as part of your fluid intake.
