Laxative Dependency: A Troubling Trend

If you are only able to defecate with the use of a laxative, you are likely experiencing chronic constipation. Laxatives are typically used to treat constipation by softening stools or stimulating the bowels, and they are usually a last resort after lifestyle changes such as increasing fibre intake, drinking more fluids, and exercising have been attempted. While laxatives can provide relief, they are not recommended for long-term use as they can lead to side effects such as bloating, gas, stomach cramps, and dehydration. In some cases, overuse of laxatives can worsen constipation and cause laxative dependency. Therefore, it is important to consult with a healthcare professional before taking laxatives, especially if you are experiencing chronic constipation.

Laxatives should not be the first treatment for constipation

Laxatives are a type of medicine that can treat constipation. They are often used if lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped. While laxatives can be effective in providing relief, they should not be the first line of treatment. This is because they can cause several side effects and may even worsen constipation if overused or misused.

Side Effects of Laxatives

Laxatives contain chemicals that help increase stool motility, bulk, and frequency, thereby relieving temporary constipation. However, when misused or overused, they can lead to problems, including chronic constipation. Laxatives can cause side effects such as bloating, gas, and stomach cramps. They can also lead to dehydration, which can result in feelings of lightheadedness and headaches, and cause darker-coloured urine. Overuse of laxatives can result in more severe complications, including electrolyte imbalance, intestinal obstruction, and interference with the absorption of certain vitamins and prescription medications.

Lifestyle Changes as a First Treatment

Before resorting to laxatives, it is advisable to try lifestyle changes, which are often effective in addressing constipation. These include:

• Increasing fibre intake: Eating high-fibre foods, such as fruits, vegetables, and whole grains, can help soften stools and improve bowel function. Fibre supplements, such as psyllium, methylcellulose, and wheat dextrin, are also available over the counter.
• Drinking more fluids: Staying hydrated by consuming at least eight 8-ounce cups of water or other fluids, such as teas and soups, daily can help prevent constipation.
• Exercising regularly: Physical activity can help improve digestive function and promote regular bowel movements.

When to Consider Laxatives

If constipation persists despite implementing lifestyle changes, laxatives may be considered. It is important to consult a healthcare provider or pharmacist before taking laxatives to ensure their safe and proper use. They are usually recommended for occasional or short-term constipation and should be taken as directed to prevent side effects. Bulk-forming laxatives, such as fibre supplements, are generally considered the gentlest option and are often suggested as a first-line treatment among laxatives.

Laxative abuse can lead to dehydration, electrolyte imbalance, worsened constipation, and UTI risk

Laxatives are a convenient solution for addressing occasional constipation. However, laxative abuse can lead to several health issues, including dehydration, electrolyte imbalance, worsened constipation, and an increased risk of urinary tract infections (UTIs).

Dehydration

Laxatives can cause dehydration due to excessive fluid loss. Symptoms of dehydration include reduced urine output, muscle weakness, dizziness, thirst, inability to urinate, dark urine, confusion, and dry mouth. In severe cases, dehydration can lead to hypovolemic shock and even death.

Electrolyte Imbalance

Excessive laxative use can disrupt the balance of electrolytes like potassium, sodium, and calcium in the body. Electrolytes are essential for regulating heartbeat, blood pressure, muscle movements, and digestion. Electrolyte imbalances can negatively affect kidney and heart function and, in some cases, lead to fatal complications such as coma, seizures, and cardiac arrest.

Worsened Constipation

Over time, laxative abuse can make constipation worse. Laxatives "overwork" the digestive tract, reducing muscle tone and nerve signaling, which slows down digestive muscle contractions. This can lead to a condition known as "lazy" or atonic colon, where the colon becomes less responsive to normal signals for bowel movements.

Increased Risk of Urinary Tract Infections (UTIs)

Chronic dehydration from excessive laxative use can increase the risk of UTIs. The concentrated urine can irritate and injure the urethra, making it more vulnerable to bacterial infection. Symptoms of a UTI may include pain or burning during urination, abdominal cramping, blood in the urine, and a frequent urge to urinate.

It is important to use laxatives sparingly and only as directed to prevent these potential side effects and health complications. If you are experiencing constipation, it is recommended to first try lifestyle changes such as increasing fiber intake, staying hydrated, and exercising regularly. If these changes do not help, consult a healthcare professional before taking laxatives.

Laxatives are available without a prescription and include bulk-forming, osmotic, stool softeners, lubricants, and stimulants

Laxatives are a type of medicine used to treat constipation. They are available over the counter without a prescription and can be bought at pharmacies, grocery stores, and online. They may be labelled as laxatives, stool softeners, or fibre supplements.

There are several types of laxatives, including bulk-forming, osmotic, stool softeners, lubricants, and stimulants.

Bulk-forming laxatives, also known as fibre supplements, work by increasing the bulk or weight of the stool, which stimulates the bowel. They are considered the gentlest type of laxative and are usually recommended as the first option. They include psyllium (Metamucil), polycarbophil (FiberCon), and methylcellulose (Citrucel).

Osmotic laxatives draw water from the body into the bowel, softening the stool and making it easier to pass. They include polyethylene glycol (MiraLAX), magnesium hydroxide solution (Milk of Magnesia), and glycerin (Colace Glycerin).

Stool softeners, also called emollient laxatives, increase the water and fat content in the stool, making it softer. An example is docusate (Colace).

Lubricant laxatives, such as mineral oil, coat the colon and prevent water absorption, keeping the stool soft and making it easier to pass.

Stimulant laxatives activate the nerves controlling the muscles in the colon, forcing it into motion. They are recommended if other over-the-counter types have not helped. Examples include bisacodyl (Dulcolax) and senna (Fletcher's Laxative).

It is important to follow the instructions when taking laxatives to prevent side effects such as bloating, gas, and stomach cramps. They should be used sparingly and only when needed, as overuse can lead to chronic constipation and other complications.

Stimulant laxatives can cause cramping, diarrhoea, and dependency if overused

Laxatives are medicines that treat constipation by softening hard stools or stimulating your bowels to get moving so you can pass them. They contain chemicals that help increase stool motility, bulk, and frequency, thus relieving temporary constipation. However, they can cause problems when misused or overused, including chronic constipation.

Stimulant laxatives, in particular, can cause cramping, diarrhoea, and dependency if overused. They trigger the intestines to contract and push out the stool. The active ingredient in stimulant laxatives is usually either senna (also known as sennosides) or bisacodyl. Some popular brands include bisacodyl (Correctol, Dulcolax, Feen-a-Mint), and sennosides (Ex-Lax, Senokot). Prunes (dried plums) are also an effective colonic stimulant.

Stimulant laxatives are one of the faster-acting types of laxatives. They work by stimulating the lining of the intestine, thereby accelerating the stool's journey through the colon. They also increase a stool's hydration. However, they may cause cramping and diarrhoea.

It is important to note that stimulant laxatives should not be used daily or regularly. Overuse can lead to laxative dependency and weaken the body's natural ability to defecate. They can be habit-forming and harmful to the bowels if used for an extended period. Therefore, it is recommended to use them sparingly and only when necessary.

If you find yourself needing to use laxatives frequently or trying one laxative after another, it is important to consult your doctor. They can offer other medications or therapies that may be more effective than over-the-counter laxatives.

Bulk-forming laxatives are the gentlest option and are recommended as the first choice

Bulk-Forming Laxatives: The Gentlest Option

Bulk-forming laxatives are recommended as the first choice for treating constipation due to their gentle action and low risk of side effects. They are different from stimulant laxatives, which speed up bowel movement, and lubricant laxatives, which lubricate stools.

Bulk-forming laxatives work by absorbing liquid in the intestines, creating a softer, more liquid-like stool that is easier to pass. They are often the first line of defence before other types of laxatives are used. They are also safe to use daily.

Common bulk-forming laxatives include psyllium (Metamucil), polycarbophil (FiberCon), and methylcellulose (Citrucel). These laxatives are available over the counter in pharmacies, grocery stores, and online, and are generally safe for healthy people. However, they should be taken with at least 8 ounces of water or fruit juice to prevent bowel obstruction, and it is important to stay well-hydrated throughout the day.

While bulk-forming laxatives are gentle, they may cause mild side effects such as stomach pain, bloating, or gas. More serious side effects include difficulty swallowing, difficulty breathing, and allergic reactions. People with kidney disease or diabetes should consult a doctor before use, as they are at risk of electrolyte imbalances.

Bulk-forming laxatives are a good option for those experiencing chronic constipation due to diet, lifestyle, recent surgery, or medication. They can also be beneficial during pregnancy or after giving birth, and for treating constipation in bedridden individuals. They may also help with reducing cholesterol and treating diarrhoea.

When to Try Other Options

While bulk-forming laxatives are recommended as a first choice, they may not be suitable for everyone. If your stool remains hard after trying a bulk-forming laxative, you can try an osmotic laxative in addition to or instead of the bulk-forming laxative. Osmotic laxatives draw water from the body into the bowel to soften the stool. Common osmotic laxatives include polyethylene glycol (MiraLAX) and magnesium hydroxide solution (Milk of Magnesia).

If your stool is soft but still difficult to pass, you can try taking a stimulant laxative in addition to a bulk-forming laxative. Stimulant laxatives activate the nerves that control the muscles in the colon, forcing it into motion. However, they should not be used daily as they may weaken the body's natural ability to defecate and cause laxative dependency.
