Laxatives: What Sensations To Expect And How They Work

Laxatives are a type of medicine used to treat constipation. They are available over the counter and by prescription, and can be taken orally or rectally. While laxatives can provide constipation relief, they can also cause side effects such as abdominal cramps, dehydration, and diarrhoea. Some people experience severe pain and discomfort when using laxatives, while others find them effective and gentle. It is important to speak with a doctor or pharmacist to determine the most suitable type of laxative and to avoid potential interactions with other medications.

Cramps, nausea, vomiting, and diarrhoea are common side effects

Cramps are one of the most commonly reported side effects of laxatives. Some people have described the severity of these cramps as comparable to childbirth pains or second-stage labour contractions. The cramps may be accompanied by other symptoms such as sweating, shivering, dizziness, and weakness. In some cases, the cramps have been so severe that people considered calling an ambulance or sought medical attention in an emergency room. It is important to note that stimulant laxatives, which work by triggering intestinal contractions, may be associated with more intense cramps.

Nausea and vomiting are also common side effects of laxative use. Some people have reported experiencing severe nausea, sometimes accompanied by dry heaving or vomiting. This may be related to the dosage or frequency of laxative use, as some individuals have reported taking multiple tablets in a short period. It is important to follow the recommended dosage instructions and not exceed the suggested amount to minimise the risk of these side effects.

Diarrhoea is another possible side effect of laxatives. This is often a result of the laxative's effect on softening stools and increasing bowel movement frequency. In some cases, diarrhoea may be mild and resolve within a day. However, for others, it can be explosive and persistent, lasting for several days. It is important to stay hydrated and replace lost fluids if experiencing diarrhoea to avoid dehydration.

In addition to these common side effects, some people may experience other adverse reactions such as dehydration, which can lead to lightheadedness, headaches, and darker urine. It is important to drink plenty of fluids while taking laxatives to minimise the risk of dehydration. Additionally, overuse or prolonged use of laxatives can lead to intestinal obstruction, where large, dry stools become lodged in the intestines. Therefore, it is recommended to only take laxatives occasionally and for a short duration, typically up to a week at a time. If constipation persists or side effects become severe, it is important to consult a healthcare professional for advice.

Laxatives can cause intestinal blockage and electrolyte imbalance

Laxatives are a common medication used to relieve constipation. They work by softening stools or increasing their bulk with additional fibre. While they are typically available over the counter without a prescription, laxatives can cause several side effects, including intestinal blockage and electrolyte imbalance.

In terms of how they feel, laxatives can cause abdominal cramps and may lead to dehydration, resulting in symptoms such as lightheadedness, headaches, and dark urine. However, the most serious side effects are intestinal blockage and electrolyte imbalance, which can have severe health consequences.

Intestinal blockage, or bowel obstruction, occurs when stools become large and dry due to excessive or prolonged use of laxatives. This condition can be dangerous and may require surgical intervention. In some cases, it can even lead to the rupture of the bowel. For example, a case study reported a 21-year-old man who presented to the Emergency Department with lower abdominal pain and constipation. He was treated with the laxative psyllium, but his condition worsened, and he later returned to the hospital with increased abdominal distension. He was diagnosed with an incomplete intestinal obstruction resulting from the ingestion of psyllium husks without adequate fluid intake.

Electrolyte imbalance is another potential consequence of laxative use, particularly an imbalance of potassium, which is necessary for the proper functioning of nerves and muscles, including the colon and heart. Dehydration caused by diarrhoea, a common side effect of laxatives, can lead to this imbalance. This imbalance can, in turn, affect the functioning of these organs.

To avoid these complications, it is important to drink plenty of fluids when taking laxatives and to only take them occasionally and for short periods. Additionally, individuals with Crohn's disease or ulcerative colitis should not take laxatives unless specifically instructed to do so by their doctor. It is also crucial to read the instructions carefully and follow the recommended dosage to minimise the risk of side effects.

They can be taken orally or rectally

Laxatives are available in various forms, including liquids, tablets, capsules, suppositories, and enemas. They can be taken orally or rectally, depending on the type and the user's preference.

Oral laxatives are typically available as tablets, capsules, or liquids. They are convenient and easy to use, and some people may find them more comfortable than rectal administration. Oral laxatives work by stimulating the digestive tract, softening the stool, or increasing the amount of water in the intestines to promote bowel movements. Examples of oral laxatives include osmotics, bulk formers, and stool softeners.

Rectal laxatives, on the other hand, are administered directly into the rectum. They can be in the form of suppositories or enemas. Rectal laxatives work by softening the stool and triggering contractions in the intestinal muscles, making it easier to pass.

It is important to note that laxatives should be used occasionally and for a short period, typically up to a week. They are not recommended for long-term use as they can cause side effects such as dehydration, diarrhoea, intestinal obstruction, and electrolyte imbalances. Before taking any laxative, it is advisable to consult a healthcare professional to determine the most suitable type and dosage for your specific needs.

Bulk-forming laxatives are considered safe for daily use

Laxatives are medicines that stimulate or facilitate bowel movements. They are commonly used to relieve constipation. Most laxatives are available over the counter and without a prescription. However, it is still recommended to talk to a doctor or pharmacist about your needs and which type of laxative may be best for you.

There are five primary types of over-the-counter laxatives: osmotics, bulk formers, oral stool softeners, stimulants, and rectal suppositories. Bulk-forming laxatives, also known as fiber supplements, are considered a first-line solution for adults with constipation unless there is a specific reason not to use them. They work by increasing the bulk of stools by getting them to retain liquid, which encourages the bowels to push them out. Common bulk-forming laxatives include psyllium (Metamucil), polycarbophil (FiberCon), and methylcellulose (Citrucel).

Bulk-forming laxatives are generally safe for daily use, even for those who are pregnant or breastfeeding. They are also often preferred as they provide a more gradual improvement of constipation symptoms and have a lower risk of causing cramping or explosive diarrhea compared to other types of laxatives. However, it is important to drink plenty of fluids when taking bulk-forming laxatives to prevent bowel obstruction. Additionally, those with kidney disease or diabetes should consult their doctor before using bulk-forming laxatives as they are at risk of electrolyte imbalances.

While bulk-forming laxatives are considered safe for daily use, it is important to follow the recommended dosage and not to overuse them. Overuse of laxatives can lead to intestinal muscle and nerve response loss, resulting in dependency on the laxatives for bowel movements. It is also important to note that laxatives should not be used as a long-term solution, and lifestyle changes such as increasing fiber intake, improving diet, and increasing activity can help reduce constipation and the need for laxatives.

They are not recommended for children or people with certain health conditions

Laxatives are a type of medicine that can treat constipation. They are available over the counter and via prescription. While laxatives can be effective, they are not recommended for children unless advised by a doctor. This is because laxatives can have adverse side effects, and children are more susceptible to these effects. For instance, one user review of the laxative Dulcolax (bisacodyl) describes a 14-year-old girl who took four pills and experienced violent diarrhoea.

Laxatives are also not recommended for people with certain health conditions, such as Crohn's disease or ulcerative colitis. This is because laxatives can worsen constipation in people with these conditions by decreasing the colon's ability to contract. Additionally, people with intestinal blockages should not use stimulant laxatives, as they can be harmful. Furthermore, laxatives can interact with other medications, such as heart medications, antibiotics, and bone medications. Therefore, it is important to consult a doctor or pharmacist before taking laxatives, especially if one has an existing health condition or is taking other medications.

Laxatives can also cause dehydration, which can lead to lightheadedness, headaches, and dark urine. This is a particular concern for children, as they are more susceptible to the effects of dehydration. In addition, overuse of laxatives can lead to intestinal muscle and nerve response loss, resulting in dependency on the medication. This is another concern for children, as their intestinal function may be more easily disrupted.

Overall, while laxatives can be an effective treatment for constipation, they are not recommended for children or people with certain health conditions. It is important to consult a healthcare professional before taking laxatives to ensure they are safe for your individual circumstances.
