The Laxative Conundrum: Examining The Effects On Elderly Health

Constipation is a common problem in older adults, with a prevalence of 16% in adults over 60 and up to 50% in nursing home residents. It is a clinical diagnosis based on symptoms of incomplete elimination of stool, difficulty passing stool, or both. Constipation may be primary (functional constipation) or secondary, associated with chronic disease processes, medication use, and psychosocial issues.

The treatment of constipation in older adults should be tailored to the individual and often involves a combination of approaches. Non-pharmacological interventions include behavioural interventions such as scheduled toileting after meals, increased fluid intake, and increased dietary fibre intake. Biofeedback to retrain the defecation muscles may be effective for treating constipation caused by pelvic floor dysfunction.

Pharmacological treatments include bulking agents, osmotic laxatives, stool softeners, stimulant laxatives, chloride channel activators, and peripherally acting mu-opioid antagonists. The choice of treatment depends on the patient's goals, the presence of any impaction, and the response to previous treatments.

Laxatives are often used to treat constipation in the elderly

Constipation is a common problem in older adults, with an estimated prevalence of over 65% in people over 65. It can have a serious impact on quality of life and well-being, and can also lead to more severe problems such as abdominal pain, haemorrhoids, and irritability in people with Alzheimer's or dementia.

• Osmotic agents, such as polyethylene glycol (brand name Miralax), sorbitol, and lactulose. These work by drawing water into the stool to keep it softer and easier to pass. They are generally well-tolerated and can be used daily.
• Stimulant agents, such as senna (Senokot) and bisacodyl (Dulcolax). These stimulate the colon to move things along more quickly and can be used as a "rescue agent" or daily if needed.
• Bulking agents, such as soluble fibre supplements like psyllium (Metamucil) and methylcellulose (Citrucel). These work by making the stool bigger and easier for the colon to move along. However, they must be taken with plenty of water, and older adults with very slow bowels may become impacted by the extra fibre.

When treating constipation in older adults, it is important to first identify and address any underlying causes, such as medication side effects, insufficient dietary fibre or water intake, or electrolyte imbalances. Lifestyle changes, such as increasing fibre and fluid intake and establishing a regular toilet routine, are usually the first line of treatment. If these measures are insufficient, over-the-counter laxatives can be added to help establish and maintain regular bowel movements. It is often necessary to try different types of laxatives or combinations to find the most effective regimen for an individual.

It is a myth that using laxatives long-term is dangerous or risky. There is no scientific evidence to support the idea that chronic laxative use will result in a "lazy" bowel. In fact, the American Society of Gastroenterology notes that stimulant laxatives do not appear to damage the enteric nervous system. However, it is still important to use laxatives correctly and only when necessary, as they can have side effects such as abdominal cramping, bloating, and diarrhoea.

Laxatives can be used in the short-term with reasonable safety

Laxatives can be used in the short term with reasonable safety. However, it is important to note that laxatives should not be used as a long-term solution for constipation. Laxatives are meant to be used occasionally and not as a permanent fix for constipation.

Laxatives are often used to treat constipation, which is a common problem among older adults. Constipation can cause abdominal pain, hemorrhoids, irritability, and fecal incontinence. It can also lead to more serious problems such as fecal impaction, which is when a hard mass of stool gets stuck in the rectum or colon.

There are several types of laxatives available, including bulk-forming laxatives, osmotic laxatives, and stimulant laxatives. Bulk-forming laxatives, such as psyllium and bran, are generally well-tolerated and can be effective in treating constipation. Osmotic laxatives, such as lactulose and polyethylene glycol, work by drawing water into the stool to make it softer and easier to pass. Stimulant laxatives, such as senna and bisacodyl, stimulate the colon to move things along more quickly.

While laxatives can be effective in treating constipation, it is important to use them with caution. Some laxatives, such as magnesium hydroxide, can cause an increase in blood magnesium levels, especially in those with kidney problems. Additionally, stimulant laxatives can cause abdominal cramping, bloating, and nausea. It is also important to note that laxatives should not be used for more than a few weeks without consulting a healthcare provider, as they can disrupt electrolytes in the body.

In conclusion, laxatives can be used in the short term to treat constipation with reasonable safety. However, it is important to use them appropriately and not as a long-term solution. It is also crucial to consult a healthcare provider to ensure the safe and effective use of laxatives.

Laxatives are more effective than a placebo in treating elderly constipation patients

Laxatives are often used to treat constipation in elderly patients. This is because constipation is a common problem in older adults, with an estimated prevalence of 24% to 30% in this age group. The condition can significantly impact an individual's quality of life and is associated with various complications, such as abdominal pain, haemorrhoids, and faecal incontinence.

Several types of laxatives are available, including bulk-forming agents, osmotic laxatives, and stimulant laxatives. These work by increasing the weight and water-absorbent properties of the stool, drawing water into the stool to keep it softer, and stimulating the colon to move things along more quickly, respectively.

The use of laxatives in elderly patients has been the subject of numerous randomised controlled trials (RCTs). These studies have found that laxatives, including psyllium, calcium polycarbophil, lactulose syrup, lactitol, polyethylene glycol, and magnesium hydroxide, are more effective than a placebo in treating elderly constipation patients in the short term (up to three months). Polyethylene glycol, in particular, has been found to be safe and effective for long-term use (up to six months) in this population.

However, it is important to note that the quality of the available studies is generally not high, with small sample sizes and short treatment durations. Additionally, most studies did not assess adverse effects using standardised techniques, and the frequency and types of adverse effects were generally similar between the treatment and placebo groups.

In conclusion, while laxatives can be an effective treatment option for elderly constipation patients, more high-quality research is needed to establish definitive recommendations.

Laxatives can be used in conjunction with other treatments

Laxatives are often used in conjunction with other treatments to manage constipation in elderly patients. This is because constipation in older adults is often multifactorial, resulting from a combination of factors such as medication side effects, insufficient dietary fibre or water intake, and underlying health conditions.

The first step in treating constipation is usually identifying and addressing any constipating medications, increasing fibre and fluid intake, and encouraging a regular toilet routine. If these measures are insufficient, over-the-counter (OTC) laxatives can be added to help establish and maintain regular bowel movements.

There are three types of OTC laxatives that have proven efficacy: bulk-forming fibre supplements, osmotic laxatives, and stimulant laxatives.

Bulk-forming fibre supplements

These supplements, such as psyllium (brand name Metamucil) and methylcellulose (brand name Citrucel), work by increasing the bulk of the stool, making it easier for the colon to move it along. They must be taken with plenty of water, as older adults who take these supplements without enough hydration can become impacted by the extra fibre.

Osmotic laxatives

Osmotic laxatives, including polyethylene glycol (brand name Miralax), sorbitol, and lactulose, draw extra water into the stool to keep it softer and easier to pass. They are generally well-tolerated and can be used daily.

Stimulant laxatives

Stimulant laxatives, such as senna (brand name Senakot) and bisacodyl (brand name Dulcolax), stimulate the colon to contract and move things along more quickly. They can be used as "rescue agents" to prompt a bowel movement if there hasn't been one for a couple of days, or they can be taken daily if needed.

It's important to note that laxatives should be used in conjunction with lifestyle changes, such as increasing fibre and fluid intake and regular physical activity. This combination of approaches is endorsed as the first-line therapy for constipation by the American Gastroenterology Society and other medical organisations.

When used correctly, these laxatives are considered safe and do not appear to cause any long-term problems. However, it's important to understand how each type of laxative works and to follow the recommended dosage to avoid adverse effects.

Laxatives can be used to treat constipation caused by medication

Constipation is a common issue for elderly people, and it can significantly impact their quality of life and well-being. Laxatives can be used to treat constipation in the elderly, but it's important to proceed with caution as they can have side effects and interactions with other medications.

Laxatives can be an effective treatment for constipation caused by medication in elderly people. Medications that can cause constipation as a side effect include nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and antidepressants. Before turning to laxatives, it's recommended that people make dietary and lifestyle changes, such as increasing their fluid intake, eating more fibre-rich foods, and exercising regularly.

If these changes do not help, over-the-counter (OTC) laxatives can be tried. Bulk-forming laxatives, such as psyllium, are generally not effective for medication-induced constipation as they increase the bulk of the stool without helping it move. Osmotic laxatives, like polyethylene glycol (brand name Miralax), are often recommended as they draw water into the stool, making it softer and easier to pass. Stimulant laxatives, like senna and bisacodyl, stimulate the colon to move things along more quickly. They can be used as a "rescue agent" or daily if needed.

It's important to note that laxatives should be used with caution and under medical supervision, especially in elderly individuals who may have other health issues or be taking multiple medications.
