Laxatives: Small Intestine Transformation?

Laxatives are a type of medicine that help people pass stools when they are constipated. They work by softening hard stools or stimulating the bowels to get moving. There are several different types of laxatives, each with a different effect on the digestive system. For example, bulk-forming laxatives contain fibre, which soaks up water in the intestines and produces bulkier stools. Osmotic laxatives draw water from the body into the gut, softening stools and increasing the movement of the small and large intestines. Lubricant laxatives coat the colon, making it easier for stools to pass through. While laxatives can be effective, they should not be the first option to relieve constipation. Lifestyle changes, such as eating high-fibre foods, taking probiotics, drinking more fluids, and exercising, are recommended as the first course of action.

Laxatives are a type of medicine that can treat constipation

There are several types of laxatives, including bulk-forming laxatives, osmotics, stool softeners, lubricants, and stimulants. Bulk-forming laxatives, also known as fibre supplements, are generally considered the gentlest type and are often recommended as the first option. They work by adding soluble fibre to the stool, drawing water from the body into the stool to make it bigger and softer, stimulating the colon to contract and push out the stool. Examples of bulk-forming laxatives include psyllium (Metamucil®), polycarbophil (FiberCon®), and methylcellulose (Citrucel®).

Osmotic laxatives, such as polyethylene glycol (MiraLAX®) and magnesium hydroxide solution (Dulcolax®, Ex-Lax®), pull water from other parts of the body into the colon, softening the stool and making it easier to pass. Stool softeners, also known as emollient laxatives, increase the water and fat absorption of the stool, making it softer. Lubricant laxatives, such as mineral oil, coat the colon, preventing water absorption from the stool and making a slippery passage for easier stool movement.

Stimulant laxatives, such as bisacodyl (Dulcolax®) and senna (Fletcher's® Laxative), activate the nerves controlling the muscles in the colon, forcing it to move the stool along. Stimulant laxatives are typically recommended only when other over-the-counter types have not been effective. It is important to note that stimulant laxatives come with a higher risk of side effects, such as diarrhoea and stomach cramps.

While laxatives can be effective in treating constipation, they should be used with caution and only as directed to prevent side effects. Overuse of laxatives can lead to complications such as dehydration, electrolyte imbalance, chronic constipation, and intestinal blockage. Additionally, laxatives do not treat the underlying cause of constipation and can delay diagnosis if there is an underlying condition. Therefore, it is recommended to consult a healthcare provider if constipation persists despite lifestyle changes and laxative use.

Bulk-forming laxatives stimulate the bowel by increasing the weight of poo

Laxatives are a type of medicine used to treat constipation. They are available over the counter in pharmacies and supermarkets, as well as on prescription from a doctor. There are four main types of laxatives: bulk-forming, osmotic, stool softeners, and lubricants.

Bulk-forming laxatives work by increasing the weight of the faecal matter, which in turn stimulates the bowel. They are considered the gentlest type of laxative and are often recommended as the first line of treatment for constipation. They are also generally safe for healthy individuals. Bulk-forming laxatives absorb liquid in the intestines, which creates a softer and more liquid-like stool that is easier to pass. They typically take between 12 hours to three days to work.

Some common bulk-forming laxatives include:

• Psyllium (Metamucil)
• Polycarbophil (FiberCon)
• Methylcellulose (Citrucel)

It is important to note that laxatives should not be used as a first-line treatment for constipation. Instead, lifestyle changes such as increasing fibre intake, drinking plenty of fluids, and exercising regularly should be implemented first. If these changes do not help, then laxatives can be considered under medical supervision.

Osmotic laxatives draw water from the body into the bowel to soften poo

Laxatives are a type of medicine used to treat constipation. They are available over the counter and by prescription. Osmotic laxatives are a type of laxative that draws water from the body into the bowel to soften the stool, making it easier to pass. They are used to treat or prevent constipation and are available over the counter and by prescription.

Osmotic laxatives 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 equalise the concentration on both sides. In the context of constipation, osmotic laxatives alter the balance by introducing substances such as salts, sugars, and other organic compounds that encourage water to move into the lumen (the inside of the colon). This process helps to soften the stool and alleviate constipation.

Osmotic laxatives differ from other types of laxatives, such as emollient, lubricant, and stimulant laxatives, in that they can be used to prevent or treat chronic constipation, while others are typically used for occasional constipation. Osmotic laxatives include polyethylene glycol (PEG), found in products like Miralax and GlycoLax; lactulose, a prescription laxative; sorbitol, available over the counter and by prescription; magnesium citrate, sold as Citrate of Magnesia, Citroma, and LiquiPrep; and magnesium hydroxide, a milder form of magnesium found in Milk of Magnesia.

It is important to follow the dosing instructions carefully when using osmotic laxatives and to only use them when needed. Overuse of osmotic laxatives can lead to dehydration and other potentially serious complications. They should not be used long-term as they can interfere with the body's chemistry. Common side effects of osmotic laxatives include nausea, bloating, cramping, flatulence, and diarrhoea.

If you are experiencing chronic constipation, it is recommended to consult a healthcare provider to identify the underlying cause. In some cases, lifestyle changes such as diet, exercise, and increased fluid intake may be sufficient to improve the condition.

Lubricant laxatives coat the colon to retain stool fluid

Lubricant laxatives, such as mineral oil, are used to treat constipation by coating the colon and stool in a waterproof film. This coating has a twofold effect: it prevents the colon from absorbing water from the stool, thus retaining moisture in the stool, and it also makes for a slippery passage, facilitating easier defecation. Typically, lubricant laxatives take effect within 6 to 8 hours, providing relief from constipation.

However, it is important to note that lubricant laxatives are not recommended for long-term use. They should not be used for more than a week, as prolonged use has been associated with vitamin deficiencies and potential interactions with certain medications. This is because the coating can affect how the body absorbs other substances. For this reason, pregnant women and individuals with difficulty swallowing are advised to refrain from using lubricant laxatives.

Lubricant laxatives are typically used for immediate relief from short-term constipation. They are not suitable for regular or chronic constipation management. Instead, bulk-forming laxatives, which are generally considered the gentlest option, are often recommended as the first line of treatment for constipation. These laxatives contain soluble fibre, which draws water into the stool, making it softer and easier to pass. They are safe for long-term use and are well-tolerated by most individuals.

If you are experiencing constipation, it is important to consult with your healthcare provider before taking any laxatives. They can guide you in choosing the most suitable option for your specific needs and ensure that you take the appropriate dosage. Additionally, making dietary and lifestyle changes, such as increasing fibre and fluid intake and engaging in regular physical activity, can also help alleviate constipation.

Laxatives are available over the counter or on prescription

There are four main types of laxatives: bulk-forming, osmotic, poo-softener, and stimulant. Bulk-forming laxatives work by increasing the weight of the stool, which stimulates the bowel. Osmotic laxatives draw water from the body into the bowel to soften the stool and make it easier to pass. Poo-softener laxatives let water into the stool to soften it. Stimulant laxatives activate the nerves that control the muscles in the colon, forcing it to move the stool along.

Most laxatives are available without a prescription and are meant for occasional or short-term constipation. However, taking them for too long can cause side effects and worsen constipation. You may need a prescription laxative if over-the-counter options are not working or if you have a chronic condition that causes constipation. Prescription laxatives are safer for long-term use and are prescribed for treating chronic constipation, constipation related to a condition such as irritable bowel syndrome (IBS), and opioid-induced constipation.

It is important to take laxatives as directed to prevent side effects such as bloating, gas, and stomach cramps. Laxatives should only be taken occasionally and for up to a week at a time. If your constipation does not improve after taking laxatives for a week, you should consult a doctor.
