Saline laxatives are used to treat constipation or to cleanse the colon before a colonoscopy or surgery. They work by retaining water in the intestine through osmosis, increasing the bulk of the stool. This softens the stool, making it easier to pass and increasing the pressure in the intestine, which in turn makes bowel movements more frequent.

What You'll Learn
Saline laxatives work by increasing fluid in the small intestine
Saline laxatives are used to treat constipation or to cleanse the colon in preparation for a colonoscopy. They work by increasing the amount of water the intestine absorbs, which softens the stool, making it easier to pass. This also increases pressure in the intestine, prompting the muscles in the intestines to move the stool along.
Saline laxatives are a type of osmotic laxative. They contain salt that holds water in the colon. The water is retained in the intestine through osmosis, increasing the bulk of the stool. The stool formed stimulates the intestinal muscles to contract naturally, causing the faeces to move along. This is known as peristalsis.
Osmotic laxatives pull water from other body parts and send it to the colon. As the water collects, it softens the stool, making it easier to pass. This can take anywhere from 30 minutes to six hours.
Saline laxatives are not intended for long-term use or for pregnant women. They are also not suitable for children under five years old unless directed by a doctor.

They are used to treat constipation
Saline laxatives are used to treat constipation and work by increasing the amount of water in the intestine, which softens the stool. This increase in water retention is caused by the salts in saline laxatives, which contain highly charged ions that do not cross the intestinal walls and remain inside the intestine. This process is known as osmosis.
The softened stool puts pressure on the intestinal walls, which stimulates the intestinal muscles to contract naturally, making bowel movements more frequent. This process usually results in a bowel movement after 30 minutes to 6 hours.
Saline laxatives are typically recommended for the relief of occasional constipation. However, it is advised that you use milder products, such as stool softeners or bulk-forming laxatives, whenever possible. For most people with constipation, bulk-forming laxatives or stool softeners are safer and more effective.
Saline laxatives are also used to clean the colon and intestines in preparation for surgery or certain bowel procedures, such as a colonoscopy.

Saline laxatives are usually prescribed alongside other products to clean the stool from the intestines before surgery or certain bowel procedures.
Saline laxatives are not suitable for everyone. They should not be used by young children or pregnant women, for example. They can also cause serious side effects such as kidney problems, dehydration, and cardiac arrhythmia. It is important to follow the instructions on the package and not to take more than the recommended dosage.

They should not be used for more than 3 days without consulting a doctor.
Saline laxatives work by retaining water in the intestine through osmosis. They contain salts with highly charged ions that do not cross the intestinal walls and remain inside the intestine.

It is important to drink plenty of clear liquids when taking saline laxatives to avoid dehydration.
Saline laxatives are generally considered safe for short-term use, but they can cause side effects such as electrolyte imbalance and cardiac arrhythmia (irregular heartbeat). They are not suitable for everyone and should not be used by pregnant women or children under 5 without medical advice. They may also interact with certain medications, so it is important to consult a doctor or pharmacist before use.

They can cause mild abdominal discomfort, gas, or nausea
Saline laxatives are used to treat constipation or to cleanse the colon in preparation for a colonoscopy. They work by increasing the amount of water the intestine absorbs, which softens the stool and increases pressure, making bowel movements more frequent.
Saline laxatives are usually well-tolerated, but they can cause some mild side effects, such as abdominal discomfort, gas, or nausea. These side effects are typically mild and transient, but if they persist or worsen, it is important to consult a doctor or pharmacist.
Abdominal discomfort can occur due to the increased water retention and pressure in the intestine. The intestine may feel temporarily distended or cramped as it works to push the softened stool along. This can also lead to increased gas, which may contribute to feelings of abdominal discomfort or bloating.
Nausea is another potential side effect of saline laxatives. It is important to drink plenty of clear liquids when taking these laxatives to avoid dehydration, which can exacerbate nausea. In most cases, nausea related to saline laxatives is mild and resolves once the laxative has taken effect and the bowel movement occurs.
It is important to remember that the benefits of using saline laxatives generally outweigh the risks of mild side effects. However, if any of these side effects persist or become bothersome, it is always best to consult a healthcare professional for advice and to ensure proper usage.

Frequently asked questions
Saline laxatives are primarily used to treat occasional constipation. They are also used to clean the stool from the intestines before certain procedures or surgeries.
Saline laxatives contain salts with highly charged ions. These ions remain inside the intestine, retaining water through osmosis, which increases the bulk of the stool. The larger stool then stimulates the intestinal muscles to contract naturally, aiding the passage of feces.
Saline laxatives are known to be fast-acting, typically resulting in a bowel movement within 30 minutes to 6 hours of ingestion.
Side effects may include mild abdominal discomfort, gas, nausea, and dehydration. More serious side effects can include electrolyte imbalance, cardiac arrhythmia (irregular heartbeat), kidney problems, and allergic reactions.
No, saline laxatives are not recommended for children under 5 years of age unless directed by a doctor. They are also not suitable for those with certain medical conditions, such as dehydration, kidney disease, or bowel problems. Additionally, they may interact with other medications, so it is important to consult a healthcare professional before use.
