There is evidence to suggest that laxatives can cause insomnia. A study published in the Canadian Journal of Neurological Sciences found that laxative users had a 7.1% lower sleep efficiency, a 25.5-minute higher wake after sleep onset, and a 29.4-minute lower total sleep time than patients not using laxatives. The study also found that laxative users were more likely to report insomnia symptoms.
Laxatives are a type of medicine used to treat constipation. They are available over the counter and on prescription. While they can be effective in treating constipation, they may also have side effects, including dehydration, increased constipation, and diarrhoea.
If you are experiencing insomnia or other side effects from taking laxatives, it is important to speak to your healthcare provider. They may recommend alternative treatment options or suggest adjusting the timing of your medication.

What You'll Learn
Laxatives can cause poorer polysomnography-derived sleep quality
Laxatives are indeed associated with poorer polysomnography-derived sleep quality. A study published in the Canadian Journal of Neurological Sciences found that laxative users had a 7.1% lower sleep efficiency, a 25.5-minute higher wake after sleep onset, and a 29.4-minute lower total sleep time than patients not using laxatives. The study also found that laxative users were more likely to report insomnia symptoms than non-users.
The study, conducted by researchers at the Sunnybrook Health Sciences Centre in Toronto, Canada, analyzed polysomnography data from 2946 patients over the age of 40. The researchers found that laxative use was associated with impairments in objective sleep continuity, including lower sleep efficiency, longer wakefulness after sleep onset, and reduced total sleep time.
The findings suggest that laxative use may disrupt sleep patterns and contribute to insomnia symptoms in middle-aged and elderly individuals. The study highlights the need for physicians to recognize the potential impact of laxative use on sleep quality and to consider alternative treatments for chronic constipation that may have fewer sleep-related side effects.
Furthermore, the study also found that the use of different types of laxatives, such as stool softeners and stimulant laxatives, was associated with similar impairments in sleep continuity. This indicates that the negative impact on sleep quality may not be limited to a specific type of laxative.
While the study provides valuable insights into the relationship between laxative use and sleep quality, it is important to note that it has some limitations. The presence of constipation was inferred based on self-reported laxative use, and the frequency or dosage of laxative medications was not available. Additionally, the study was cross-sectional, which prevents establishing causal inferences between laxative use and sleep disturbances.
Laxatives: Types and How They Work

Laxatives can cause dehydration
Laxatives should be taken occasionally and for up to a week at a time. Prolonged use can lead to diarrhoea, intestinal obstruction, and electrolyte imbalances. It is important to read the label and take laxatives as directed to avoid harmful side effects. If constipation persists or worsens, it is recommended to consult a doctor.
In addition to dehydration, laxatives have also been associated with poorer sleep quality. A study found that laxative users had lower sleep efficiency, longer wake times after sleep onset, and shorter total sleep times than non-users. As a result, laxative users were more likely to report insomnia symptoms. Therefore, it is essential to be aware of the potential side effects of laxatives and consult a healthcare provider if any concerns arise.

Laxatives can cause diarrhoea
Laxatives are a common medication used to treat constipation. They work by drawing water into the gut or by causing the muscles of the intestines to contract, facilitating bowel movements. However, it is important to recognise that laxatives can cause diarrhoea.
Diarrhoea is a well-known side effect of taking laxatives, and it can occur when the laxative causes the intestines to contract too much or draws too much water into the gut. This can lead to loose, watery stools, which characterise diarrhoea. While laxatives are intended to relieve constipation, taking too much can result in diarrhoea that may be problematic. Antacids containing magnesium and antibiotics can also contribute to this issue.
The risk of diarrhoea is not limited to oral laxatives; rectal suppositories can also lead to this condition. Additionally, certain herbal teas, vitamins, minerals, or supplements may have a similar effect. It is crucial to be cautious when consuming these products to avoid diarrhoea.
Diarrhoea resulting from laxative use can have further consequences, such as dehydration and electrolyte imbalance. This highlights the importance of using laxatives appropriately and consulting a healthcare professional when needed.
To prevent diarrhoea, it is advisable to talk to your healthcare provider about taking supplements with healthy bacteria (probiotics) or consuming yoghurt alongside antibiotic treatment. Continuing these supplements for a few days after completing the antibiotics may also be beneficial.

Laxatives can cause intestinal obstruction
While laxatives are a common treatment for constipation, they are not without risks. One of the potential side effects of laxative use is intestinal obstruction. This occurs when the bowel becomes blocked by large, dry stools. In addition, overuse of laxatives can lead to the intestines losing muscle and nerve response, resulting in dependency on laxatives for bowel movements.
Laxatives work by stimulating or facilitating bowel movements. There are several types of laxatives available, including bulk-forming laxatives, osmotic laxatives, stool softeners, and stimulant laxatives. Bulk-forming laxatives increase the "bulk" or weight of the stool, stimulating the bowel. Osmotic laxatives draw water into the colon, softening the stool and making it easier to pass. Stool softeners work by letting water into the stool, making it softer and easier to pass. Stimulant laxatives encourage bowel movements by triggering rhythmic contractions of the intestinal muscles.
While laxatives can be effective in treating constipation, they should not be used as a first-line treatment. It is recommended to first make dietary and lifestyle changes, such as increasing fibre intake, drinking plenty of fluids, and exercising regularly. Laxatives should only be used occasionally and for up to a week at a time. If constipation persists after a week of laxative use, it is advised to consult a healthcare provider.
In addition to intestinal obstruction, other side effects of laxatives include dehydration, increased constipation, diarrhoea, and electrolyte imbalance. Laxatives can also interact with other medications, such as heart medications, antibiotics, and bone medications. Therefore, it is important to speak with a healthcare provider or pharmacist before taking laxatives to ensure they are safe and appropriate for your individual needs.

Laxatives can cause an electrolyte imbalance
The body's electrolyte balance is regulated by the gut, which absorbs and secretes electrolytes through the movement of fluids and ions. This process is controlled by various factors, including the enteric nervous system, autonomic nervous system, central nervous system, endocrine signaling, microbiota, ion channels, and aquaporins.
Laxatives can affect this delicate balance by altering gut motility and fluid and electrolyte absorption and secretion. For example, some laxatives may increase intestinal fluid secretion, soften stools, and accelerate peristalsis, which is the movement of food through the digestive tract. This can lead to a loss of electrolytes and fluid imbalance. Additionally, some laxatives may affect the expression of aquaporins, which are channels in the intestinal tract that regulate water movement. Changes in aquaporin expression can impact fluid homeostasis and contribute to electrolyte imbalances.
It is important to note that not all laxatives will cause electrolyte imbalances, and the risk may depend on the type of laxative, dosage, and individual factors. However, it is crucial to use laxatives with caution and follow the instructions provided by a healthcare professional to minimize the risk of adverse effects.
