Best Laxatives for Constipation in the Elderly (2026 Guide)

Constipation is a common health problem among the elderly, affecting a significant percentage of the aging population. It can result in discomfort, pain, and in some cases, a profound impact on overall health. With age, the digestive system undergoes changes that can slow down peristalsis, the involuntary contractions that move food through the digestive tract. Factors such as medication use, poor diet, dehydration, and reduced physical activity can further exacerbate constipation in older adults.

For many, laxatives become a crucial part of managing this condition. However, with a variety of options available, choosing the right one can be a challenge. Some laxatives are gentler and more suitable for long-term use, while others provide quicker relief but may come with potential side effects. In this article, we will review the best laxatives for constipation in the elderly to help you make an informed choice.

Why Constipation is Common in the Elderly

Before diving into the best laxatives, it’s essential to understand the underlying causes of constipation in older adults:

1. Slower Digestive System: As people age, intestinal motility decreases, slowing the movement of food through the digestive system.
2. Medications: Many medications commonly prescribed to the elderly, such as pain relievers, antacids, and blood pressure medications, can contribute to constipation.
3. Dehydration: Older adults are more prone to dehydration, and insufficient fluid intake can make stools complex and challenging to pass.
4. Reduced Physical Activity: With aging, people often become less active, and physical inactivity can contribute to constipation.
5. Dietary Changes: A diet low in fiber and high in processed foods can lead to difficulty passing stool.

How Laxatives Work and When to Use Them

Laxatives are used to relieve constipation by promoting bowel movements. However, they come in various types and work in different ways:

• Bulk-forming Laxatives: These are fiber-based and help increase stool volume by absorbing water. They are the gentlest option and are often recommended for long-term use.
• Stimulant Laxatives: These stimulate intestinal muscles, promoting bowel movements. While effective, they should be used sparingly due to potential side effects like dehydration or dependency.
• Osmotic Laxatives: These draw water into the colon, softening the stool and making it easier to pass.
• Stool Softeners: These increase stool water content, making it easier to pass without straining.

The choice of a laxative depends on the severity of the constipation, any underlying health conditions, and whether the constipation is short- or long-term.
