Constipation, characterized by infrequent bowel movements or difficulty passing stools, can significantly impact daily life. When lifestyle adjustments like increased fiber intake and hydration aren’t enough, medication may be necessary. Several types of medicines can stimulate bowel movements and alleviate constipation.

Types of Laxatives
Laxatives are medications designed to treat constipation. They work through various mechanisms to soften stool, increase bowel motility, or draw water into the intestines.
Bulk-Forming Laxatives
These laxatives, such as psyllium (Metamucil), increase stool bulk, which stimulates bowel movements. They work by absorbing water in the intestines, making the stool softer and easier to pass.
Osmotic Laxatives
Osmotic laxatives like polyethylene glycol (Miralax) draw water into the colon, softening the stool and making it easier to pass. Magnesium citrate and magnesium hydroxide (Milk of Magnesia) are also osmotic laxatives.
Stimulant Laxatives
Stimulant laxatives, including bisacodyl (Dulcolax) and senna (Senokot), stimulate the intestinal muscles to contract, promoting bowel movements. They are generally used for short-term relief of constipation.
Stool Softeners
Docusate sodium (Colace) is a stool softener that increases the amount of water absorbed by the stool, making it softer and easier to pass. They are often recommended to prevent straining during bowel movements.
Lubricant Laxatives
Mineral oil is a lubricant laxative that coats the stool and intestinal lining, making it easier for the stool to pass. However, it is not recommended for long-term use.
Prescription Medications
In some cases, prescription medications may be necessary to treat chronic constipation. These include:
- Lactulose: An osmotic laxative.
- Linaclotide (Linzess) and Plecanatide (Trulance): These medications increase fluid secretion in the intestines and accelerate bowel transit.
- Prucalopride (Motegrity): A selective serotonin receptor agonist that stimulates bowel movements.
Important Considerations
It’s crucial to consult a healthcare professional before using any laxative, especially if you have underlying health conditions or are taking other medications. Overuse of laxatives can lead to dependency and other health problems.
Lifestyle changes, such as increasing fiber intake, drinking plenty of water, and regular exercise, are often the first line of defense against constipation. If these measures are not effective, a healthcare provider can recommend the most appropriate medication.
Remember to always follow the instructions and precautions provided by your doctor or on the medication label.
сегодня
Beyond specific medications, certain medical conditions and even some medications taken for other ailments can contribute to constipation. Discussing your complete medical history with your doctor is essential for proper diagnosis and treatment.
Other Factors Affecting Bowel Movements
- Medical Conditions: Conditions like irritable bowel syndrome (IBS), hypothyroidism, and neurological disorders can affect bowel function.
- Medications: Certain medications, such as opioids, antidepressants, and iron supplements, are known to cause constipation as a side effect.
- Dehydration: Insufficient fluid intake can lead to hard, dry stools that are difficult to pass.
- Diet: A diet low in fiber can contribute to constipation.
- Lack of Physical Activity: Regular exercise helps stimulate bowel movements.
When to See a Doctor
Constipation is usually not a serious condition, but it’s important to see a doctor if you experience any of the following:
- Severe abdominal pain
- Blood in your stool
- Unexplained weight loss
- Changes in bowel habits that last for more than two weeks
- Constipation that doesn’t improve with over-the-counter treatments
A healthcare professional can determine the underlying cause of your constipation and recommend the most appropriate treatment plan.
