What fibers should I focus on for treating constipation in adults?

To relieve constipation in adults, it is recommended to focus on increasing the intake of dietary fiber found in fruits, vegetables, whole grains, and legumes as part of a balanced diet. Fiber makes stool softer and easier to pass. It is essential to accompany an increase in fiber with the consumption of ample amounts of fluids and water, as the success of this plan depends on the presence of fluids, which help fiber perform its function effectively [4].

The Importance of Fiber in Relieving Constipation

Dietary fiber helps regulate bowel movements. Constipation is medically defined as having fewer than three bowel movements per week, and the stool is often hard or dry, making it painful to pass [1]. By focusing on a variety of fiber sources, you can improve stool consistency and reduce the chances of experiencing occasional constipation [1].

Recommended Sources of Fiber

To improve your daily fiber intake, it is preferable to rely on natural and varied food sources. Recommended sources include:

• Whole grains: Such as whole wheat bread, whole wheat pasta, oats, and wheat bran cereal [4].
• Legumes: Such as lentils, black beans, kidney beans, soybeans, and chickpeas [4].
• Fruits: Such as berries, apples (with the skin), oranges, and pears [4].
• Vegetables: Such as carrots, broccoli, green peas, and collard greens [4].

Adults should consume between 22 to 34 grams of fiber daily, depending on age and gender [4].

How to Increase Fiber Intake Safely

The process of increasing fiber intake should be done gradually so your body can adjust to the change. It is also important to drink plenty of water and other fluids, such as naturally sweetened fruit and vegetable juices and clear soups, to help the fiber work better and make the stool softer and easier to pass. Staying hydrated also helps avoid dehydration and is beneficial for general health [4].

Medical Warnings and Considerations

While fiber is an essential part of a healthy diet, it is not a substitute for medical evaluation in cases of chronic or changing constipation. If you notice a significant and persistent change in bowel habits, it is essential to consult a doctor to rule out any underlying causes. For more details on medical measures and when precise procedures are required, you can view the article Constipation in Adults: Causes, Treatment, and When a Colonoscopy Is Needed (Arabic). Also, remember that some herbal supplements, such as flaxseed, require caution; raw or unripe flaxseed should be avoided as it contains compounds that may be toxic. It is recommended to consult a doctor before introducing them as a supplement, especially if you are taking other medications such as blood thinners, due to the potential for drug interactions [3].
