Laxative Effects: When To Expect The Next Movement

Laxatives are a type of medicine used to treat constipation. They work by softening stools or stimulating the bowels to get moving. They are typically taken when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped with constipation. Laxatives are available over the counter in pharmacies, grocery stores, and online, as well as on prescription from a doctor. It is important to take laxatives as directed to prevent side effects such as bloating, gas, and stomach cramps, and to avoid taking more than the recommended dose. While laxatives can provide relief for constipation, they should not be taken daily as they can lead to dependence and worsening constipation.

Laxatives should be taken as directed to prevent side effects such as bloating, gas or stomach cramps

Laxatives are a type of medicine used to treat constipation. They are available over the counter and on prescription. There are several types of laxatives, including bulk-forming laxatives, osmotic laxatives, poo-softener laxatives, and stimulant laxatives.

Laxatives should always be taken as directed to avoid side effects. Bulk-forming laxatives, for example, can be taken daily and are considered safe. However, they can cause side effects such as flatulence and bloating. Osmotic laxatives, such as polyethylene glycol, can cause gas, bloating, and nausea. Therefore, it is important to follow the recommended dosage and not to take them for extended periods.

Stimulant laxatives, such as senna and bisacodyl, can lead to dependency if overused. They should only be taken occasionally and for up to a week at a time. Stop taking them as soon as your constipation improves. If your constipation persists after a week of taking laxatives, consult a doctor.

Laxatives can also cause dehydration, which may result in lightheadedness, headaches, and dark-coloured urine. They can also lead to diarrhoea, intestinal obstruction, and electrolyte imbalances. Therefore, it is important to drink plenty of fluids when taking laxatives and to seek medical advice if you experience any persistent or troublesome side effects.

It is worth noting that constipation can often be relieved through lifestyle changes, such as increasing fibre and fluid intake and regular exercise. These are generally better methods for preventing constipation than relying on laxatives.

Bulk-forming laxatives are considered the gentlest and are the best laxative to try first

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

Bulk-forming laxatives are considered the gentlest type of laxative and are usually the best option to try first. They work by increasing the bulk or weight of the stool, which stimulates the bowel. This is done by drawing water into the stool, making it softer and easier to pass. They are also similar to stool softeners in that they help the bowels retain water. Bulk-forming laxatives include Fybogel (ispaghula husk), psyllium (Metamucil), polycarbophil (FiberCon), and methylcellulose (Citrucel).

Unlike some other types of laxatives, such as stimulant laxatives, bulk-forming laxatives do not stimulate nerves that speed up the movement of bowels through the intestines. They also do not lubricate the stools like lubricant laxatives. Osmotic laxatives differ from bulk-forming laxatives by helping the intestines, rather than the bowels, retain water.

Bulk-forming laxatives are a good option for people who experience chronic constipation due to diet, lifestyle, recent surgery, or medication. They are also beneficial during pregnancy or after giving birth, during preparation for surgery, for treating constipation in bedridden people, and for preventing strain after surgery. They may also help with reducing cholesterol and treating diarrhoea.

It is important to note that while bulk-forming laxatives are generally safe, they can cause side effects such as mild stomach pain, bloating, gas, and allergic reactions. People with kidney disease or diabetes are at a higher risk of electrolyte imbalances when taking laxatives, so it is important to consult a doctor before use. Additionally, laxatives may impact how the body absorbs medications, so it is recommended to take any medication at least two hours before or after taking a laxative.

When taking bulk-forming laxatives, it is important to drink plenty of fluids to prevent dehydration. They usually take 12 hours to three days to provide relief.

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

Osmotic laxatives are a type of medication used to treat constipation by drawing water from the body into the bowel, softening stools, and making them easier to pass. They work by increasing the amount of fluid in the intestines, which helps to soften stools and ease their passage. This process is known as osmosis, where fluid moves through a membrane to equalise concentration on both sides.

Osmotic laxatives are particularly useful for people who do not consume enough water, as they can help compensate for the low water concentration in the colon. They are also used for bowel preparation before medical procedures like a colonoscopy.

Some common osmotic laxatives include polyethylene glycol (found in brands like Miralax and GlycoLax), lactulose (a type of sugar that ferments in the intestines, available by prescription), and magnesium-based laxatives like Milk of Magnesia. It is important to follow the dosing instructions carefully and only use laxatives when needed, as overuse can lead to dehydration and other complications.

Osmotic laxatives are different from other types of laxatives like emollient, lubricant, and stimulant laxatives. While osmotic laxatives draw water into the stool, emollient laxatives use surfactants to encourage the spread of fats and water, lubricant laxatives use oily substances to aid stool passage, and stimulant laxatives cause intestinal contractions to push out stools.

Stool softeners are also called emollient laxatives

Stool softeners, also known as emollient laxatives, are a type of laxative that can provide relief from constipation. They are typically used to treat mild and temporary constipation, and are especially beneficial for those who should avoid straining during bowel movements due to heart conditions, hemorrhoids, or other issues.

Stool softeners work by increasing the amount of water and fat that mixes with the stool, preventing dry, hard masses from forming. This makes the stool softer and easier to pass without straining. The active ingredients in stool softeners are typically docusate sodium and docusate calcium, with common brands including Colace® and Dulcolax®.

Stool softeners are available in various forms, including oral softgel capsules, tablets, liquids, and syrups, as well as rectal enemas. They are generally taken at bedtime and can take between 12 to 72 hours to start working. It is important to follow the directions on the packaging or consult a healthcare provider for specific instructions.

While stool softeners are considered safe, they may cause side effects such as stomach pain, nausea, diarrhoea, and throat irritation. It is recommended to consult a doctor if the constipation persists for more than a week or if there are any severe side effects.

In summary, stool softeners, or emollient laxatives, are a gentle and effective option for treating mild and temporary constipation. They work by softening the stool, making it easier to pass, and are available in various forms. However, it is important to use them as directed and consult a healthcare provider if needed.

Lubricant laxatives coat the colon, making it slippery and preventing the absorption of water from the stool

Lubricant laxatives are used to treat constipation by coating the colon with a layer of lipids, making it slippery. This coating prevents the absorption of water from the stool, keeping it soft and allowing for easier passage through the colon. Mineral oil is commonly used as a lubricant laxative, which can be purchased over the counter.

Lubricant laxatives are an effective short-term solution for constipation. However, prolonged use may lead to decreased absorption of fat-soluble vitamins and certain prescription medications. It is important to note that mineral oil should not be taken simultaneously with other medications or supplements.

The onset of action for lubricant laxatives is relatively quick, typically within 6 to 8 hours. This makes them a good option for those seeking fast relief from constipation. However, it is crucial to follow the instructions on the medication to prevent potential side effects, such as bloating and gas.

Lubricant laxatives are generally safe for adults. However, they are not recommended for children and infants due to the risk of lipid pneumonia resulting from accidental aspiration. As with all laxatives, lubricant laxatives should only be used when necessary and not as a long-term solution for constipation. If constipation persists or is accompanied by other symptoms, it is important to consult a healthcare professional.
