Gentle Laxatives: How Do They Work And What Do They Do?

Gentle laxatives are used to treat constipation or to empty the bowels before a medical procedure. They are available in many forms, including oral tablets, capsules, suppositories, and enemas. Gentle laxatives work by increasing the amount of fluid or salts in the intestines, softening the stool, and stimulating bowel movements. They can be purchased over the counter or prescribed by a doctor. While they are generally safe, overuse of gentle laxatives can lead to bowel function impairment and laxative dependence. It is important to follow the directions on the package or consult a doctor for proper use.

How gentle laxatives work

Gentle laxatives are used to treat constipation or to empty the bowels before a medical procedure. They can also be used to treat constipation that arises as a result of lifestyle factors such as inadequate fluid intake, a lack of fibre in the diet, and insufficient physical activity.

Gentle laxatives work by stimulating bowel movements. They do this by increasing the amount of fluid and salts in the intestines, which results in a bowel movement within 15 to 60 minutes.

There are several types of gentle laxatives, including bulk-forming laxatives, osmotic laxatives, and emollient laxatives (stool softeners). Bulk-forming laxatives increase the weight of the stool, which in turn stimulates the bowel. Osmotic laxatives draw water from the body into the bowel to soften the stool and make it easier to pass. Stool softeners, on the other hand, work by letting water into the stool to soften it.

It is important to note that laxatives should only be used occasionally and for up to a week at a time. They should not be used as a long-term solution for constipation, as this can lead to laxative dependence and other health issues.

When to use gentle laxatives

Gentle laxatives are used to treat constipation by softening hard stools or stimulating the bowels to get moving. They are typically recommended for those experiencing occasional constipation that hasn't improved with lifestyle changes, such as increasing fibre intake, taking probiotics, drinking more fluids, and exercising.

Laxatives are also suitable for individuals with chronic conditions that cause constipation, like Crohn's disease or ulcerative colitis. They may also be used for a bowel cleanse before a medical procedure.

It's important to note that laxatives are not safe for everyone. Consult a healthcare provider before taking laxatives during pregnancy or giving them to children. Additionally, some laxatives can interfere with the absorption of certain medications, so it's crucial to discuss their use with a healthcare provider if you're taking prescription drugs.

Gentle laxatives, such as bulk-forming laxatives, are generally considered the safest option. They work by drawing water into the stool, making it softer and easier to pass. These laxatives usually take a few days to provide relief and are safe for daily use. They are also the best option to try first, unless a healthcare provider recommends otherwise.

Another gentle option is a stool softener, which adds moisture to the stool, making it softer. Mineral oil, a lubricant, is also effective in helping stools pass more easily, especially if they feel stuck or in cases of internal tears or pain from haemorrhoids. However, mineral oil should not be taken for an extended period as it interferes with vitamin absorption.

How to use gentle laxatives

Gentle laxatives are used to treat constipation or to empty the bowels before a medical procedure. They can be taken orally or rectally, and work by stimulating bowel movements. When taken orally, gentle laxatives typically take 6 to 12 hours to produce a bowel movement, while rectal suppositories can produce results in as little as 15 to 60 minutes.

• Oral gentle laxatives: Follow the directions on the package or take as directed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Overuse of laxatives can lead to improper bowel function and laxative dependence. Do not crush, chew, or break oral tablets. Swallow the tablet whole with a full glass of water. Avoid drinking milk or taking an antacid within 1 hour before taking the laxative.
• Rectal suppositories: Wash your hands before and after use. Remove the foil wrapper from the suppository. If desired, moisten the suppository with lukewarm water, but do not use petroleum jelly or mineral oil as this may reduce the effectiveness of the product. Lie on your left side with your right knee slightly bent and gently insert the suppository, pointed end first, towards the navel and well up into the rectum. Stay in this position for 15 to 20 minutes, if possible, until you feel a strong urge to have a bowel movement. Do not use more than one rectal suppository per day.
• General instructions: Drink plenty of fluids when taking gentle laxatives, as they can cause dehydration. Avoid taking other medications within 2 hours before or after using the laxative. Do not give this medicine to children under 2 years old without medical advice. Consult your doctor if you do not have a bowel movement after using the laxative or if you experience any side effects.

It is important to note that laxatives should only be used occasionally and for up to a week at a time. They are not a substitute for lifestyle changes such as increasing fibre and fluid intake, and regular exercise, which are more effective ways of preventing constipation.

Side effects of gentle laxatives

Gentle laxatives, also known as bulk-forming laxatives, are often recommended as the first line of treatment for constipation. They are considered safe and gentle on the body, but they may still cause some side effects, especially if not used correctly.

Bulk-forming laxatives work by drawing water into the stool, making it softer and easier to pass. They are meant to stimulate the intestinal muscles to contract and create a natural bowel movement. However, if not taken with enough water, they can sometimes lead to intestinal gas, bloating, cramping, and even increased constipation. To avoid these side effects, it is essential to consume plenty of fluids when taking bulk-forming laxatives. Starting with a lower dose and gradually increasing it can also help prevent these issues.

Lubricant laxatives, such as mineral oil, can also cause some side effects if used for an extended period. They are meant to be used as a short-term solution and can interfere with vitamin absorption if taken for too long. They may also interact with certain medications, affecting their absorption. Therefore, it is recommended to avoid taking mineral oil with other medications or supplements.

Osmotic laxatives, which include polyethylene glycol (MiraLAX), can also have side effects such as gas, bloating, and nausea. These laxatives draw water into the intestines, and if not taken with enough fluids, they can lead to dehydration and an increased risk of gas and cramps.

Stimulant laxatives are another option but are generally not recommended for regular use. They can cause cramping and diarrhea and may weaken the body's natural ability to defecate. Over time, they can lead to laxative dependency, and the bowel may stop functioning correctly.

Overall, while gentle laxatives are generally safe, it is important to follow the instructions and consume enough fluids to avoid potential side effects. If constipation persists or worsens, it is recommended to consult a healthcare professional for guidance.

Precautions when using gentle laxatives

Gentle laxatives are a great way to relieve constipation, but there are some precautions to be aware of when using them. Here are some detailed instructions and important considerations to ensure safe and effective use:

• Follow the instructions carefully: It is crucial to take laxatives exactly as directed by your doctor or the product package. Do not take more or less than the recommended dosage or exceed the suggested frequency. Laxatives can be taken in various forms, including pills, capsules, liquids, suppositories, and enemas, and each form has specific instructions to ensure safe and effective use.
• Be mindful of timing: Some laxatives need to be taken at specific times of the day, such as first thing in the morning or last thing at night. It is important to follow these instructions to optimize their effectiveness and minimize side effects.
• Drink adequate fluids: Laxatives, especially bulk-forming and osmotic laxatives, can cause dehydration. It is essential to drink plenty of fluids, such as water, tea, soup, or other liquids, to prevent dehydration and ensure the laxative works effectively.
• Gradually increase fibre intake: When increasing your fibre intake, either through diet or supplements, it is recommended to do so gradually. Abdominal cramping, bloating, or gas can occur when fibre intake is increased too quickly.
• Space out medication: Fibre can reduce the absorption of certain drugs, so it is advised to take your medications at least one hour before or two hours after consuming fibre. This includes both prescription medications and supplements.
• Be cautious with mineral oil: Mineral oil, often used as a lubricant laxative, should not be taken for extended periods. Prolonged use can interfere with the absorption of fat-soluble vitamins and decrease the absorption of certain prescription medications. Do not take mineral oil simultaneously as other medications or supplements.
• Avoid stimulant laxatives for immediate relief: While stimulant laxatives provide rapid relief from constipation, they can cause dependence and weaken the body's natural ability to defecate. It is recommended to opt for gentler options first and use stimulant laxatives sparingly and only when necessary.
• Be mindful of potential side effects: Laxatives can cause various side effects, including bloating, gas, stomach cramps, and dehydration. If you experience any side effects, consult your doctor or pharmacist promptly. Serious side effects may include nausea/vomiting/diarrhea that doesn't stop, muscle cramps/weakness, irregular heartbeat, dizziness, fainting, decreased urination, and mental/mood changes.
• Seek medical advice when necessary: If you find yourself constantly needing laxatives, or if they are not providing relief, consult your doctor. Constipation may be a symptom of a more serious condition, and your doctor can advise on alternative treatments or prescribe different laxatives if necessary.
• Not recommended for certain individuals: Laxatives are not suitable for everyone. They are generally not recommended for children unless advised by a doctor. Pregnant women should also exercise caution and consult their healthcare provider before taking laxatives. Additionally, individuals with certain health conditions, such as Crohn's disease or ulcerative colitis, should be cautious and seek medical advice before using laxatives.
