Laxatives: Friend Or Foe To Bowel Health?

Laxatives are a type of medication that help with constipation by making people pass stools more often. They work in different ways, such as by drawing moisture into the bowel, softening stools, lubricating the bowel, or stimulating the muscles in the bowels. While laxatives are often used to treat constipation, they can also cause bowel inflammation. For example, stimulant laxatives can cause the bowels to become dependent on them to function normally. Bulk-forming laxatives can also lead to side effects such as flatulence and bloating. In addition, laxatives can cause an electrolyte imbalance in the body and even lead to dehydration. Therefore, it is important to use laxatives with caution and under medical guidance.

Laxatives can be used to treat inflammatory bowel disease (IBD)

Laxatives are a type of medicine that cause you to pass stools more frequently. They can be used to treat constipation, which is characterised by passing fewer than three stools per week, straining during bowel movements, and passing hard, pellet-like stools. Constipation can be caused by various factors, including dehydration, diet, and underlying diseases or conditions.

There are several types of laxatives available, including bulk-forming laxatives, stool softeners, and stimulant laxatives. Bulk-forming laxatives, such as Celevac, work by drawing water into the stool to make it softer and easier to pass. Stool softeners, such as docusate sodium, add moisture to the stool to aid in its passage. Stimulant laxatives, such as senna, activate the digestive system and promote bowel movements.

It is important to use laxatives with caution and under medical guidance, as they can have adverse effects. They should not be used as a replacement for IBD treatment but rather as a way to manage symptoms. Additionally, it is crucial to ensure that laxatives are not masking symptoms of increased disease activity or complications such as intestinal blockages.

Osmotic laxatives can be used to treat constipation

Osmotic laxatives are medications used to treat or prevent constipation. They are available over the counter and by prescription. Osmotic laxatives work by drawing water from the wall of the colon to the inside of the colon, thereby softening stools and making them easier to pass.

Osmotic laxatives are typically used when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped with constipation. They are often recommended as the next step if stool softeners are not providing enough relief. Osmotic laxatives are also sometimes used for bowel preparation before a colonoscopy.

There are several types of osmotic laxatives, each with different active ingredients:

• Polyethylene glycol (PEG): An organic compound derived from petroleum that can be safely ingested to manage constipation. PEG-containing laxatives include Miralax and GlycoLax.
• Lactulose: A type of sugar that is not absorbed by the intestine. It sits and ferments in the intestines, producing fatty acids that draw water into the colon. Lactulose-containing laxatives include Cephulac, Duphalac, Kristalose, and others.
• Sorbitol: Another non-absorbable sugar with an action similar to lactulose. Sorbitol is available over the counter and by prescription, including brands such as Arlex and GeriCare.
• Magnesium citrate: Magnesium in salt form combined with citric acid. The salts help draw water into the colon. OTC versions include Citrate of Magnesia, Citroma, and LiquiPrep.
• Magnesium hydroxide: A milder form of magnesium sold under the brand name Milk of Magnesia, which is also used as an antacid.

Osmotic laxatives can cause side effects like nausea, bloating, cramping, flatulence, and diarrhoea. Overuse of these laxatives can lead to dehydration and the loss of electrolytes like sodium, calcium, and potassium. Therefore, it is important to follow the dosing instructions carefully and only use them when needed.

If you experience chronic constipation, it is recommended to consult a healthcare provider to identify the underlying cause. In some cases, dietary and lifestyle changes, such as increasing fibre and fluid intake and exercising, may be sufficient to improve the condition.

Laxatives can cause dehydration

Laxatives are intended to be used occasionally to relieve constipation. However, they can cause dehydration, which can lead to a host of other health issues.

Laxatives work by drawing water into the bowel to make stools softer and easier to pass. This can result in dehydration if not careful. Dehydration can cause a range of symptoms, including lightheadedness, headaches, darker urine, tremors, fainting, weakness, blurred vision, and kidney damage. In extreme cases, dehydration can lead to organ damage and even death.

It is important to drink plenty of fluids when taking laxatives to avoid dehydration. The recommended daily water intake is about 2 liters per day. However, individuals should also pay attention to their bodies and drink more if they feel thirsty.

Laxative abuse, or overuse, can also lead to electrolyte imbalances, as laxatives can interfere with the body's absorption of electrolytes such as sodium and potassium. Electrolyte imbalances can cause tremors, vomiting, urinary tract infections, kidney failure, muscle spasms, and heart attacks.

Furthermore, overusing laxatives can wear away the protective mucus that lines the colon, leaving it susceptible to infections and irritable bowel syndrome. It may also contribute to bowel tumors and colorectal cancer, although more research is needed to fully understand this link.

Therefore, it is important to use laxatives sparingly and only when necessary. They should not be used for weight loss, as they do not prevent the body from absorbing calories. Misuse of laxatives is relatively common and can lead to serious health complications and even death.

Laxatives can be addictive

Laxatives are commonly used to treat constipation, but they can be addictive. They are available over the counter without a prescription and are easy to obtain. However, laxatives are intended to be taken for a short period, and overuse can lead to several health issues.

Laxatives are available in several forms, such as tablets, capsules, powders, liquids, suppositories, and enemas. They work by increasing the bulk of the stool, softening the stool, or stimulating the bowels. While they are meant to be taken occasionally as per the recommendation of a doctor, some people misuse them for weight loss or to achieve their ideal body weight. This misuse can lead to addiction and serious health complications.

Laxative abuse occurs when someone uses laxatives to lose weight or achieve their ideal body image. Studies have shown that laxatives do not promote long-term weight loss and have minimal effects on caloric intake. Despite this, many people, especially those with eating disorders, misuse laxatives in an attempt to purge calories or food. This abuse can lead to a cycle of misuse and increased dosage as the body becomes accustomed to the effects.

The chronic and long-term use of laxatives can cause severe health issues, including dehydration, electrolyte disturbances, mineral deficiencies, and intestinal paralysis. It can also lead to gastrointestinal damage and bowel nerve damage, resulting in poor intestinal function. In some cases, laxative abuse has been associated with an increased risk of colon cancer.

The overuse of laxatives can also lead to psychological dependence, as individuals become unable to have normal bowel function without them. This dependence can be challenging to break, and stopping laxative use may require professional treatment. It is important to use laxatives with caution and only as directed by a healthcare professional to avoid the potential for misuse, abuse, and addiction.

Laxatives can be used to treat ulcerative colitis

Ulcerative colitis is a chronic inflammatory bowel disease that affects the lining of the large intestine and, in some cases, the rectum. It causes inflammation and ulceration in the colon, which can lead to constipation. Constipation occurs when it is difficult to pass stools or when a person passes stools less often than usual.

Laxatives are a type of medication that can be used to treat constipation in people with ulcerative colitis. They work by increasing the frequency of bowel movements and softening the stools to make them easier to pass. However, it is important to use laxatives with caution and under medical guidance as they can have adverse effects.

There are several types of laxatives that can be used to treat ulcerative colitis constipation:

• Osmotic laxatives: These laxatives, such as polyethylene glycol (found in brands like MiraLAX and Glycolax), increase the amount of water in the intestines, softening the stools. They are slow-acting and usually take 2-3 days to produce a bowel movement.
• Bulk-forming laxatives: These contain water-absorbent plant fibres that help to soften hard stools. They are considered the gentlest type of laxative and are generally safe for people with ulcerative colitis, except during flare-ups.
• Stimulant laxatives: These stimulate contractions in the intestinal muscles, encouraging bowel movements. They work quickly, usually within 6-12 hours, but can cause dependence if used too frequently.
• Stool softeners: These allow more water and fat to be absorbed into the stools, making them softer and easier to pass. Examples include docusate sodium and mineral oil emollients.

In addition to laxatives, there are other remedies for ulcerative colitis constipation, including lifestyle and dietary changes. Increasing fluid intake, consuming a high-fibre diet, and engaging in regular physical activity can help relieve constipation.
