Constipation is a common digestive issue that affects people of all ages. Laxative medicines are often used to relieve constipation and promote smooth bowel movements. They work in different ways, from softening stool to stimulating bowel activity. In this blog, we will discuss the uses, common types of laxative medications, who should take them, possible side effects, and the importance of medical guidance before use.

What Are Laxative Medicines?

Laxatives are medications that help ease bowel movements by loosening stool or stimulating the intestines. They are generally used for short-term relief of constipation, bowel preparation before medical procedures, or in certain medical conditions where regular bowel movement is necessary.

Uses of Laxative Medicines

• Relief from occasional constipation
• Preparation before colonoscopy or surgery
• Management of certain digestive conditions
• Assisting patients with limited mobility in maintaining bowel health

Common Laxative Medications

Lactulose: Lactulose is a synthetic sugar that works as an osmotic laxative. It draws water into the colon and is fermented by gut bacteria, contributing to its laxative effect. Used for chronic constipation and to reduce blood ammonia levels in certain conditions.

Bisacodyl: Bisacodyl is a stimulant laxative that directly irritates nerves in the intestinal lining, causing muscles to contract and push stool. It is fast-acting and used for short-term relief or before medical procedures.

Polyethylene Glycol (PEG): A common osmotic laxative, PEG draws and holds water in the colon to soften stool. It is well-tolerated and often recommended for chronic constipation.

Magnesium salts: Various magnesium forms, including Magnesium hydroxide, Magnesium citrate, and Magnesium sulfate, act as osmotic laxatives. They draw water into the intestines, soften stool, and stimulate bowel movement. Magnesium citrate works fast and is often used for bowel cleansing before procedures.

Isabgol: Also known as psyllium husk, it is a natural fiber that absorbs water to form a gel, adding bulk to stool and promoting bowel movements. It helps with both constipation and diarrhea and can improve cholesterol and blood sugar levels.
