Laxatives Fail: Why The Constipation Persists

There are many reasons why you might still be constipated after taking a laxative. Laxatives are a type of medicine that can treat constipation by softening hard stools or stimulating your bowels to get moving. However, they are not suitable for everyone and should only be used occasionally and for up to a week at a time. If your constipation has not improved after taking laxatives for a week, it is recommended that you speak to a doctor.

There are four main types of laxatives: bulk-forming, osmotic, stool softener, and stimulant. Bulk-forming laxatives work by increasing the bulk or weight of the stool, which in turn stimulates your bowel. Osmotic laxatives draw water from the rest of the body into your bowel to soften the stool and make it easier to pass. Stool softeners let water into the stool to soften it. Stimulant laxatives stimulate the muscles that line your gut, helping them to move the stool along.

If you are still constipated after trying different types of laxatives, you should see your doctor. Constipation may be a warning sign of a more serious problem such as colon cancer, diabetes, or hypothyroidism, among others.

Laxatives take time to work, ranging from minutes to days

Laxatives can take anywhere from minutes to days to work, depending on the type of laxative used. It's important to note that laxatives should only be used occasionally and for a short period of time, and you should stop taking them as soon as your constipation improves. If your constipation does not improve after a week of taking laxatives, you should consult a doctor.

Bulk-forming laxatives, which include brands like Fybogel, Metamucil, and Benefiber, typically take 2 to 3 days to work. These laxatives increase the "bulk" or weight of the stool by helping it retain fluid, which stimulates the bowel. They are considered safe for long-term use and are often recommended as the first option.

Osmotic laxatives, such as lactulose and polyethylene glycol, usually take 2 to 3 days to work as well. They soften the stool by drawing water into it, making it easier to pass.

Stimulant laxatives, including brands like Dulcolax and Senokot, generally take effect within 6 to 12 hours. They stimulate the nerves that control the muscles lining the digestive tract, speeding up bowel movements. However, they can cause stomach cramps and should not be used too frequently, as this could lead to dependence.

Stool softener laxatives, such as Colace and Surfak, take 12 to 72 hours to work. They add moisture to the stool, making it softer and easier to pass.

Lubricant laxatives, like mineral oil, take 6 to 8 hours to be effective. They work by coating the stool in a waterproof film, allowing it to retain moisture and move more easily through the bowel.

Suppositories are the fastest-acting laxatives, providing relief within 15 to 30 minutes. They are inserted into the rectum, where they dissolve and enter the bloodstream. However, they can cause rectal irritation and may be uncomfortable for some people to use.

Saline laxatives, such as magnesium hydroxide and magnesium citrate, typically work in less than 12 hours. They can cause stomach cramps and may not be suitable for those with kidney problems or those limiting their sodium intake.

It's important to remember that the effectiveness of laxatives can vary from person to person, and they should always be used with caution. Always read the patient information leaflet and consult a doctor or pharmacist if you are unsure about which laxative to use or if you have any concerns.

You may need a prescription laxative if over-the-counter options aren't working

If you're still constipated after taking a laxative, it may be time to consult your doctor about a prescription laxative. Over-the-counter laxatives are meant for very short-term use only, and overusing them could worsen your constipation and lead to serious medical problems. They can even become addictive.

Prescription laxatives, on the other hand, are safer for long-term use under a healthcare provider's supervision. If one type of prescription laxative doesn't work for you, another might, as several types are available that work differently.

Prescription laxatives are most often prescribed for treating chronic constipation, constipation related to a condition such as irritable bowel syndrome (IBS), and opioid-induced constipation. They are not meant for rapid relief of occasional constipation but rather to keep you regular when constipation is an ongoing problem.

Before turning to laxatives for constipation, it is recommended to try lifestyle remedies such as exercising regularly, increasing dietary fibre, and not holding in bowel movements. If these changes don't help, and you find yourself still struggling with constipation, it may be time to consult your doctor about a prescription laxative.

Laxatives can cause side effects like bloating, gas, and stomach cramps

Laxatives are a type of medicine that can treat constipation. They are available over the counter and on prescription. There are several types of laxatives, including bulk-forming, osmotic, poo-softener, and stimulant laxatives. While laxatives can be effective in treating constipation, they can also cause side effects such as bloating, gas, and stomach cramps.

Bulk-forming laxatives, for example, can cause bloating and pain if not taken with enough water. They work by retaining fluid in the stool and increasing its weight and consistency. This type of laxative includes sodium or calcium salts that act as anionic surfactants, reducing the surface tension of feces and allowing water and fats to penetrate and mix with the stool, softening it. However, even slight dehydration can lead to bloating, pain, and even bowel obstruction.

Osmotic laxatives can also cause bloating, as they draw water into the intestinal tract to hydrate, soften, and propel fecal matter. If used inappropriately, they can also cause abdominal cramping and significant water loss, leading to dehydration.

Stimulant laxatives are another type that can cause abdominal pain and severe stomach cramps. They stimulate nerve bundles in the intestinal tract, triggering muscle contractions that push stool along. However, overuse of stimulant laxatives can lead to a dependency on them for bowel movements.

Therefore, it is important to be aware of the potential side effects of laxatives and to take them as directed. If you experience persistent or troublesome side effects, consult your healthcare provider or pharmacist for advice.

Laxatives are not suitable for everyone, including children and those with certain health conditions

Laxatives are a type of medication used to treat constipation. They are available over the counter at pharmacies and supermarkets, as well as on prescription from a doctor. While laxatives can be effective, they are not suitable for everyone and should be used with caution. In particular, laxatives are not usually recommended for children unless advised by a doctor.

Children can become dependent on laxatives for passing stool, so it is important to monitor the frequency of laxative dosages if they are being administered to a child. It is also crucial to follow dosage instructions closely and not give more than one type of laxative at a time. In most cases, constipation in children can be addressed through dietary and lifestyle changes, such as increasing fibre and water intake, rather than resorting to laxatives.

In addition to children, laxatives may not be suitable for individuals with certain health conditions. For example, people with Crohn's disease or ulcerative colitis should exercise caution when considering laxatives. It is important to read the patient information leaflet that comes with the medicine to ensure it is safe for you to take. If you are unsure, consult a healthcare professional such as a doctor or pharmacist.

Before resorting to laxatives, it is recommended to try lifestyle changes such as increasing fibre and fluid intake, as well as regular exercise. These measures are often more effective in preventing constipation than relying on laxatives alone. Additionally, laxatives should only be taken occasionally and for up to a week at a time. If constipation persists or recurs despite these measures, it is advisable to consult a healthcare professional for further guidance.

Lifestyle changes, such as increasing fibre intake, drinking fluids, and exercising, are often the first line of treatment for constipation

Lifestyle changes can be an effective first line of treatment for constipation. These changes can have a positive cumulative effect on your digestion and are often preferable to laxatives, which may have unpleasant side effects and can be unsafe for long-term use.

Increase Fibre Intake

A low-fibre diet is a common cause of constipation. Fibre-rich foods help improve gut function and include fruits, vegetables, whole grains, nuts, seeds, and legumes. Aim to eat 20-35 grams of fibre per day, and be sure to read food labels to track your fibre intake.

High-fibre fruits include:

• Dried figs
• Prunes
• Asian pears
• Raspberries
• Apples

Vegetables that are high in fibre include:

• Broccoli
• Carrots
• Baked potatoes with skin
• Peas
• Sun-dried tomatoes

You can also try bran cereal, beans, and whole wheat bread.

Drink Fluids

Dehydration can cause or worsen constipation, so it's important to drink plenty of fluids. Aim for at least 1.5 litres of water per day, and avoid caffeine and alcohol, as these can be dehydrating.

Exercise Regularly

Lack of physical activity can lead to constipation, especially for older adults. Exercise helps keep stool moving through the colon, and several studies suggest that exercise can help relieve constipation. Try to incorporate light exercise, such as walking, into your daily routine.

In addition to these lifestyle changes, it's important to listen to your body and use the bathroom when you feel the urge to have a bowel movement. Holding it in can weaken the signals over time and make constipation worse.
