Laxative Frequency: Navigating The Dosage Maze

Laxatives are a type of medicine that can help you empty your bowels if you're having trouble going to the toilet. They are commonly used to treat constipation and are available over the counter without a prescription. However, it is important to use laxatives safely and sparingly as they can cause side effects such as abdominal cramping, bloating, and gas, and diarrhoea. Laxatives should be used occasionally and for short periods, and it is recommended to make lifestyle changes, such as increasing fibre intake, drinking plenty of fluids, and exercising regularly, to prevent constipation.

Laxatives should be used sparingly and occasionally

Laxatives are a type of medicine that can help treat constipation. They are available over the counter at pharmacies and supermarkets, as well as on prescription from a doctor. While laxatives can provide relief from constipation, they should be used sparingly and occasionally.

Firstly, laxatives are not suitable for everyone. They are not usually recommended for children unless advised by a doctor, and some types of laxatives may be unsafe for those with certain health conditions such as Crohn's disease or ulcerative colitis. It is important to read the patient information leaflet that comes with the medication to ensure it is safe for you to take.

Secondly, laxatives can cause side effects, and these become more likely with overuse. Common side effects include dehydration, which can lead to dizziness, headaches, and dark-coloured urine. Excessive or prolonged use of laxatives can also cause diarrhoea, intestinal obstruction, and an imbalance of salts and minerals in the body.

Thirdly, laxatives should be seen as a short-term solution, as they do not address the underlying causes of constipation. Instead, it is recommended to make lifestyle changes such as increasing fibre and fluid intake and taking regular exercise, which are more effective ways of preventing constipation.

Finally, overuse of laxatives can lead to dependency, where the bowel may stop functioning normally, and the body becomes reliant on laxatives to have a bowel movement. This can create a cycle of chronic constipation and laxative use.

In conclusion, while laxatives can provide relief from constipation, they should be used sparingly and occasionally. It is important to follow the recommended dosage and duration of use, and to prioritise lifestyle changes to address the underlying causes of constipation. If constipation persists or is a frequent issue, it is advisable to consult a doctor.

Bulk-forming laxatives are recommended first

Laxatives are a type of medicine that can treat constipation. They are often used if lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped. They are available to buy over the counter from pharmacies and supermarkets, as well as online. However, laxatives are not suitable for everyone and you should consult a doctor or pharmacist if you are unsure.

Bulk-Forming Laxatives

Bulk-forming laxatives are generally considered the gentlest type of laxative. They are recommended as the first line of defence against constipation before trying other types of laxatives. They are also often recommended by doctors before a surgical procedure. They are less likely to cause side effects and usually result in a more gradual improvement of constipation symptoms.

Bulk-forming laxatives work by adding soluble fibre to your stool, drawing water from your body into your stool, and making it bigger, softer, and easier to pass. They typically take 12 hours to three days to work. Common bulk-forming laxatives include:

• Psyllium (Metamucil)
• Polycarbophil (FiberCon)
• Methylcellulose (Citrucel)
• Fybogel (ispaghula husk)

It is important to take bulk-forming laxatives with at least 8 ounces of water or fruit juice to prevent bowel obstruction and stay well-hydrated throughout the day. You should also carefully follow the dosage instructions on the label and never take more than the recommended dose.

Osmotic laxatives are used to soften stools

Osmotic laxatives are one of the four main types of laxatives, which also include bulk-forming, poo-softener, and stimulant laxatives. They work by increasing the amount of fluid in the intestines, which softens the stool and facilitates its passage. The term "osmotic" refers to the movement of fluid through a membrane to equalize concentration on both sides.

Osmotic laxatives are particularly useful for people who don't consume enough water. They alter the balance of water in the colon by using substances like salts, sugars, and other organic compounds to encourage the movement of water into the lumen (the inside of the colon). This helps to compensate for hard, dry stools, which are characteristic of constipation.

In addition to treating constipation, osmotic laxatives are sometimes used for bowel preparation before a colonoscopy. They can also be used to prevent or treat chronic constipation, while other types of laxatives are generally used for occasional constipation.

Common osmotic laxatives include polyethylene glycol (PEG), lactulose, sorbitol, magnesium citrate, and magnesium hydroxide. Some brands, like Miralax and Milk of Magnesia, are available over the counter, while others like Cephulac and Kristalose require a prescription.

It's important to follow the dosing instructions carefully when using osmotic laxatives and only use them when needed. They can cause side effects like nausea, bloating, cramping, gas, and diarrhea. Overuse of osmotic laxatives can lead to dehydration and the loss of electrolytes like sodium, calcium, and potassium, which are essential for regulating heartbeats and muscle contractions.

Stimulant laxatives speed up bowel movement

Stimulant laxatives are one of the main types of laxatives used to treat constipation. They work by stimulating the nerves that control the muscles lining your digestive tract, which speeds up the movement of your bowels. Some common stimulant laxatives include bisacodyl (Correctol, Dulcolax, Feen-a-Mint), sennosides (Ex-Lax, Senokot), and senna. Prunes, or dried plums, are also considered a natural stimulant laxative.

Stimulant laxatives are usually taken in addition to a bulk-forming laxative when stools are soft but still difficult to pass. They typically take effect within 6 to 12 hours, making them a faster option than bulk-forming or osmotic laxatives, which can take 2 to 3 days to work.

While stimulant laxatives can provide quick relief from constipation, they should not be used daily or regularly. Overuse of stimulant laxatives may lead to laxative dependency and weaken the body's natural ability to defecate. Additionally, they may cause side effects such as cramping and diarrhoea.

It is important to note that laxatives should only be used occasionally and for a short period, such as up to a week. If constipation persists or occurs frequently, it is recommended to consult a doctor or pharmacist for advice. In some cases, a doctor may prescribe a laxative to be used regularly, but this should be done under medical supervision.

To prevent constipation, it is advisable to adopt lifestyle changes such as increasing fibre and fluid intake, as well as regular exercise. These measures are generally considered a better way to prevent constipation than relying on excessive laxative use.

Stool softener laxatives increase the fluid content of stools

Stool softener laxatives, also known as emollient laxatives, work by adding a compound to stools that increases their fluid content, making them softer and easier to pass. The active ingredients in stool softeners are typically docusate sodium and docusate calcium. They are considered gentle medications with a relatively mild effect and are useful for people experiencing temporary, mild, or chronic constipation. They are also often prescribed after major surgeries, such as heart surgery or hernia repair, to avoid complications that may arise from straining during bowel movements.

Stool softeners are available in various forms, including oral softgel capsules, tablets, and liquid or syrup. They typically take between 12 to 72 hours to start working, and it is recommended to take them only when needed and as directed by a healthcare professional. It is important to note that stool softeners should not be used for more than a week without consulting a doctor.

While stool softeners are generally well-tolerated, they may cause side effects such as stomach pain, nausea, and diarrhoea. Throat irritation may also occur with oral formulations. If you experience any severe or persistent side effects, it is important to consult your healthcare provider.

It is worth noting that laxatives, in general, should be used sparingly and only when necessary. They are not recommended for long-term use, as this can lead to dependency and other health complications. Before taking any laxative, it is advisable to consult a healthcare professional, especially if you have a medical condition or are taking other medications.
