CONDITIONS & DISORDERS Table 1: Common drugs that can cause constipation6 Antihypertensive drugs, such as clonidine, calcium antagonists and ganglionic blockers, can be linked to constipation as they reduce smooth muscle contractility.
Analgesics, such as opiates and cannabinoids, are especially notorious for causing constipation.
Antidepressants, especially tricyclic antidepressants.
Anti-parkinson, antiepileptic and antipsychotic drugs are associated with constipation due to their anticholinergic and dopaminergic actions and should be avoided or combined with the regular use of laxatives.
Oral iron supplementation frequently causes constipation and, in patients in whom iron supplementation is necessary, intravenous supplementation of iron or the addition of a laxative may be options.
Antihistamines, antispasmodics and vinca alkaloids are associated with constipation as a side effect and should be replaced.

to experience functional constipation than those in hospitals or similar institutions.7,8 When looking at the older population, taking into consideration chewing difficulties/dentures, the number of high-fibre foods they are able to consume may be affected. DIETARY FIBRE
A change in diet seen in western culture is thought to have some links with the prevalence of constipation and may be a causation factor. The increase of food processing has resulted in a lower intake of fibre. Dietary fibre can be described as a component of food that includes ‘all carbohydrates that are neither digested nor absorbed in the small 28
intestine and have a degree of polymerisation of three or more monomeric units, plus lignin’.9 In simpler terms, it is ‘roughage’ in our diet that helps to regulate our bowel movements. Diets high in fibre have been linked to reducing the risk of diabetes and bowel cancer, as well as helping to lower cholesterol. Historically, fibre has been broken down into insoluble and soluble, depending on the water solubility of the fibre. Insoluble fibre is roughage, as it isn’t digested and adds bulk to our stools. Insoluble fibre consists of the structural fibres, for example cellulose, lignin and hemicelluloses, and can be found in wholegrains, wheat bran and the skins/seeds/piths of fruits and vegetables. Soluble fibre helps draw water into our stools, as
www.NHDmag.com December 2019 / January 2020 - Issue 150
CONDITIONS & DISORDERS
Both soluble and insoluble fibre sources can help with constipation.
Table 3: Tips to help increase fibre in the diet
HOW TO TREAT IT
Add nuts/seeds to cereals or soups Snack on fruit/vegetables with the skins on (apples, carrots) Choose wholegrain carbohydrates Increase fibre intake gradually and ensure adequate fluids – set an alarm or use a bottle with markings on to track fluid intake throughout the day Additional beans/pulses in stews, soups Include a high-fibre breakfast cereal Include an extra portion of vegetables with main meals
well as binding to substances such as cholesterol and glucose, slowing their absorption. The natural geI-forming fibres are pectin, gums, mucilages and some hemicelluloses, and are largely found in oats, beans, pulses and the inner flesh of fruits and vegetables.2 The terms ‘insoluble’ and ‘soluble’ have, however, been discouraged in the clinical setting, with the argument that all fibrous foods contain a mixture of both these types of fibre. Pharmaceuticals also play a role in the risk of constipation, as it is a common side effect of many drugs (see Table 1). Many diseases, in particular neurological diseases, may contribute to constipation. These include diseases that involve the nervous system, such as diabetes mellitus and autonomic neuropathy and neurogenic bowel dysfunction in diseases such as spinal cord injury, multiple sclerosis and Parkinson’s disease.
A multifactural approach is important when treating constipation; as we can see from the causes, it is often not a ‘one size fits all’. Fibre The Scientific Advisory Committee on Nutrition (SACN) released a report in 2015 which advised that the population should be aiming for 30g fibre/day.10 However, it is estimated that the UK population consumes around 17.2g/day of fibre for women, and 20.1g/day for men.11 Both soluble and insoluble fibre sources can help with constipation. Soluble fibre helps to increase faecal bulk, which can stimulate colonic transit, as well as producing greater bacterial growth (particularly when found in oat bran). Insoluble fibre provides more slowly fermentable polysaccharides, which helps to maintain the microbiomes during the transit through the colon. Foods such as prunes and kiwis have been shown to help improve constipation, likely due to the combination of different fibres that the fruits contain.12,13 When increasing dietary fibre, it is important to do this gradually and alongside increasing fluids. Increasing fibre too quickly into a diet may result in more gastrointestinal symptoms. The response should be monitored, as it may take a number of days or weeks before the effects take place. Probiotics Probiotics may also have a role in relieving constipation. Some studies have identified that certain strains of probiotics may have

CONDITIONS & DISORDERS beneficial effects. These include lactobacillus casei, Escherichia coli and Bifidobacterium lactis, which all increase stool frequency and improved consistency, and Bifidobacterium animalis, which reduces colonic transit time.15-18 However, as most studies look at probiotics and GI health, evidence is limited and, therefore, recommendations should be made on an individual basis. Medication As well as being the cause of some constipation, medications can help to relieve it. The NICE guidance advises the following on treating both short-term and chronic constipation:19 • Offer drug treatment with oral laxatives using a stepped approach. Adjust the dose, choice and combination of laxatives used, depending on the person’s symptoms, the desired speed of symptom relief, the response to treatment, and their personal preference. • Initial treatment should be with a bulkforming laxative such as ispaghula. • If stools remain hard or difficult to pass, add or switch to an osmotic laxative, such as a macrogol. • If a macrogol is ineffective, or not tolerated, offer treatment with lactulose second line. • If stools are soft but difficult to pass, or there is a sensation of inadequate emptying, add a stimulant laxative.
• If faecal loading/impaction is apparent, suppositories may be used. FURTHER RECOMMENDATIONS
NICE also recommends increasing dietary fibre and fluids (especially if dehydrated), establishing a good ‘toilet routine’ and increasing activity and exercise levels, if needed. Helpful toileting routines include the following:19 • Establish a regular, unhurried toilet routine, giving time to ensure that defaecation is complete. • Advise on responding immediately to the sensation of needing to defaecate. • Ensure that people with limited mobility have appropriate help to access the toilet with adequate privacy. • Ensure the person has access to supported seating if they are unsteady on the toilet. CONCLUSION
Constipation tends to affect the very young and the elderly and is more common in women than men. Dietary fibre plays a large role in helping with the symptoms of constipation, but when increasing dietary fibre, it is important to introduce foods gradually, making sure that hydration is increased alongside. Whilst some medications can cause constipation, drug treatment (supported by NICE19) can help in the short-term, as well as for the symptoms of chronic constipation.
