Stimulate Laxatives: What's Really In Them?

Stimulant laxatives are a type of laxative that stimulates the muscles in your colon to move stool along. They are used to treat constipation by softening hard stools or stimulating your bowels to get moving so you can pass them. They are often used when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped. Stimulant laxatives are available without a prescription and can be purchased over the counter in pharmacies, grocery stores, and online. However, they should not be used regularly or daily as they may weaken the body's natural ability to defecate and cause laxative dependency.

Bulk-forming laxatives increase the weight of stools

Bulk-forming laxatives are a type of laxative that treats constipation by increasing the bulk or weight of stools. They work by drawing water from the body into the stool, making it bigger, softer, and easier to pass. This increase in stool size stimulates the colon to contract and push out the stool.

Common bulk-forming laxatives include psyllium (Metamucil), polycarbophil (FiberCon), and methylcellulose (Citrucel). These laxatives are generally considered gentle and are often recommended as a first-line treatment for constipation. They typically take between 12 hours and three days to provide relief.

It is important to note that bulk-forming laxatives should be taken with plenty of water to prevent choking and ensure their effectiveness. Additionally, they should not be taken for more than seven days unless directed by a doctor.

Bulk-forming laxatives are different from stimulant laxatives, which speed up bowel movement through the intestines. They are also distinct from lubricant laxatives, which lubricate the stools to aid passage.

Osmotic laxatives stimulate the muscles lining the gut

Osmotic laxatives are a type of medication used to treat constipation and are available over the counter or by prescription. They work by drawing extra water into the stool, making it softer and easier to pass. Osmotic laxatives are so-called because they relate to the movement of fluid through a membrane to equalise the concentration on both sides.

Osmotic laxatives are particularly useful for people who do not consume enough water. They work by altering the balance with substances such as salts, sugars, and other organic compounds, which encourage the movement of water into the colon. This helps to soften stools and makes them easier to pass.

Common osmotic laxatives include polyethylene glycol (PEG), lactulose, sorbitol, magnesium citrate, and magnesium hydroxide. They are available under various brand names, including Miralax, GlycoLax, Cephulac, Duphalac, and Milk of Magnesia.

Osmotic laxatives are different from emollient, lubricant, and stimulant laxatives. The former works by drawing water and fat to stools, the second by lubricating stools, and the third by speeding intestinal contractions.

Lubricant laxatives coat the colon

Lubricant laxatives are used to treat constipation by coating the colon and stool in a waterproof film, allowing the stool to remain soft and slip through the intestine easily. This coating also prevents the colon from absorbing water from the stool, keeping it soft. Lubricant laxatives are also known as oily laxatives, and they are commonly used to treat fecal impaction, which is a large, hard mass of stools that gets stuck in the colon or rectum.

Lubricant laxatives are typically recommended for short-term use, as long-term use can lead to vitamin deficiencies and potential interactions with medications. They are not suitable for pregnant women or individuals who have difficulty swallowing. The most common lubricant laxative is mineral oil, which is available over the counter. Mineral oil works by adding a slick layer to the intestine's walls and preventing the stool from drying out. However, it can also absorb fat-soluble vitamins and decrease the absorption of certain prescription drugs. Therefore, it should not be taken at the same time as other medications or supplements.

Lubricant laxatives are different from bulk-forming laxatives, which add bulk and water to stools, and stool softeners, which enable easier incorporation of water into the stool. Lubricant laxatives act by coating the colon and stool, making the passage of stool easier. They are a good option for fast relief from constipation but should not be used regularly.

It is important to note that laxatives should be used sparingly and only when necessary. They should not be used as a long-term solution for constipation. Lifestyle changes, such as increasing fibre intake, drinking enough fluids, and exercising regularly, are often the best way to maintain regular bowel movements.

Stimulant laxatives activate nerves controlling muscles in the colon

Laxatives are a category of medications used to address constipation and other gastrointestinal issues. They work by enhancing digestion and promoting bowel movements, making it easier to pass stool. There are five basic types of laxatives: stimulant, osmotic, bulk-forming, stool softeners, and lubricants.

Stimulant laxatives are the focus of this query. They activate the nerves that control the muscles in the colon, forcing the colon into motion and stimulating a bowel movement. They do this by stimulating the myenteric plexus and the Auerbach plexus, increasing intestinal secretions and motility. The active ingredient in stimulant laxatives is usually either senna (also known as sennosides) or bisacodyl.

Stimulant laxatives are often used when other over-the-counter laxatives have not been effective. They can be one of the faster-acting types of laxatives, providing almost instantaneous relief from constipation. However, it is important to note that stimulant laxatives should not be used daily or regularly. This is because they may weaken the body's natural ability to defecate and can cause laxative dependency. They may also cause cramping and diarrhea.

Some common brand names of stimulant laxatives include Senexon, Fletcher's Castoria, Senokot, Black Draught, Feen-A-Mint, Correctol, Dulcolax, and Carter's Little Pills. These laxatives come in various forms, such as liquids, powders, chewables, tablets, and suppositories.

It is always recommended to consult a doctor or healthcare provider before using laxatives, especially if you are pregnant, breastfeeding, or have any health conditions.

Stool softeners enable stools to absorb more water and fat

Stool softeners are a type of laxative called an emollient laxative. They are typically used to treat mild or temporary constipation. They are often the first method used to prevent and treat constipation. Stool softeners work by increasing the amount of water and fat absorbed by the stool, making it softer and easier to pass. This is done by adding a compound to the stool that absorbs water. The active ingredients in stool softeners are usually docusate sodium and docusate calcium.

Stool softeners are particularly useful for people who should avoid straining during a bowel movement. This includes people who have recently had heart attacks or surgeries. They can also be prescribed after major surgeries, such as heart surgery or hernia repair, to avoid complications during recovery.

Stool softeners can be taken orally or rectally. They are available in the form of tablets, capsules, liquids, syrups, or rectal enemas. It is recommended to take them at bedtime with a full glass of water or juice. Relief is usually observed within 1 to 3 days of taking stool softeners. However, it is important to follow the directions on the packaging or consult a healthcare provider for specific instructions.

It is important to note that stool softeners should not be used for more than a week without consulting a healthcare provider. They are generally considered safe, but side effects may include stomach pain, nausea, diarrhea, and throat irritation.
