Constipation is more than just an inconvenience—it affects millions of people worldwide and can significantly impact daily life and overall well-being. Understanding how to manage this common digestive issue through both conventional treatments and emerging therapies is essential for anyone experiencing difficulty with bowel movements.

Addressing the Challenge of Difficult Bowel Movements

When people struggle with constipation, the primary goal of treatment is to restore comfortable and regular bowel function. This means helping individuals pass stools more easily, reducing discomfort, and preventing complications that can arise from chronic constipation. The approach to treatment depends heavily on how severe the constipation is, how long it has been present, and what might be causing it in the first place.^[1]

Treatment strategies vary widely from person to person because what works for one individual may not work for another. Some people respond well to simple dietary adjustments, while others may need medications or more specialized interventions. The key is finding the right combination of approaches that fits each person’s unique situation and medical history.^[2]

Medical societies have established standard treatments that doctors commonly recommend based on years of research and clinical experience. These approved approaches form the foundation of constipation management. At the same time, researchers continue to explore new therapies through clinical trials, seeking better and more effective ways to help people who don’t respond to traditional treatments or who experience side effects from standard medications.^[3]

The overall aim is not just to provide temporary relief but to help people achieve long-term improvement in their bowel habits and quality of life. This often involves a combination of lifestyle modifications, dietary changes, and when necessary, medications that work in different ways to address the underlying problem.^[4]

Conventional Treatment Approaches

The first line of defense against constipation typically involves lifestyle and dietary modifications. Healthcare professionals usually recommend increasing dietary fiber, which is the part of plant food that the body doesn’t digest. Adults generally need between 22 and 34 grams of fiber each day, yet only about 5% of people in the United States actually consume this amount. Fiber works by adding bulk to the stool and helping it move more smoothly through the digestive tract.^[5]

There are two main types of fiber that play different roles in digestive health. Soluble fiber absorbs water and turns into a gel-like substance, which helps soften the stool. This type of fiber is found in foods like oats, barley, beans, lentils, apples, and bananas. Insoluble fiber, on the other hand, doesn’t absorb water but adds bulk to the stool and helps it pass more quickly through the intestines. Good sources include whole grains, vegetables, and wheat bran.^[6]

Hydration is equally critical in managing constipation. Water and other fluids help fiber do its job more effectively by keeping the stool soft and easier to pass. Most people should aim for about six to eight glasses of water daily, though individual needs can vary. Hot beverages like tea or coffee may provide additional benefits by stimulating the digestive system, though caffeine has a diuretic effect, meaning it increases urine production, so additional water intake is important.^[7]

Physical activity plays a significant role in promoting regular bowel movements. Regular exercise, even something as simple as a 20-minute walk, can help stimulate the intestines and improve bowel function. Healthcare providers often recommend at least two and a half hours of moderate to vigorous exercise per week, which can include walking, swimming, cycling, or other activities that get the body moving.^[8]

When dietary and lifestyle changes aren’t sufficient, fiber supplements become the next step. These products, available over the counter, include brands like Metamucil, Citrucel, and Benefibre. They work as bulk-forming agents, adding volume to the stool and helping the bowel contract to push it out. These supplements come in various forms including powders, capsules, and even chewable tablets or gummies, making them convenient to incorporate into daily routines.^[9]

Different fiber supplements contain different active ingredients. Metamucil uses psyllium, a soluble fiber derived from plant husks. Citrucel contains methylcellulose, another type of soluble fiber. All-Bran relies on wheat bran, which is an insoluble fiber. Each type works slightly differently in the digestive system, and some people may respond better to one type than another.^[10]

Osmotic laxatives represent another category of commonly used medications. These products work by drawing water into the intestines, which softens the stool and makes it easier to pass. Polyethylene glycol, sold under the brand name Miralax, is one of the most frequently recommended osmotic laxatives. Research has shown it to be more effective than lactulose, another osmotic agent, and it produces fewer side effects like gas and bloating. Milk of Magnesia is another example of an osmotic laxative that healthcare providers may recommend.^[11]

For situations requiring faster relief, stimulant laxatives may be appropriate, though they should only be used for short periods. These medications, which include products like Dulcolax and Correctol, work by stimulating the muscles of the intestinal wall to contract and push stool through. While effective, they can cause cramping and aren’t meant for long-term use because the bowel can become dependent on them over time.^[12]

Stool softeners like Colace, which contains the active ingredient docusate, work by helping water and fats mix into the stool to make it softer. These are generally gentle and safe for short-term use. Some healthcare providers also recommend lubricants like mineral oil, which coat the stool and intestinal wall to help things slide through more easily, though these should be used carefully as they can interfere with the absorption of certain vitamins.^[7]

For individuals who don’t respond adequately to over-the-counter options, doctors may prescribe newer medications called intestinal secretagogues. These include linaclotide, sold as Linzess, and lubiprostone, marketed as Amitiza. These prescription medications work by increasing fluid secretion in the intestines, which helps soften the stool and promotes bowel movements. Clinical trials have demonstrated that both medications are more effective than placebo for chronic constipation, though they can be expensive and may not be covered by all insurance plans.^[12]

The duration of treatment varies depending on the underlying cause and severity of constipation. Some people may only need short-term intervention during a period of temporary constipation caused by travel, stress, or medication changes. Others with chronic constipation may require ongoing treatment, though the goal is always to use the lowest effective dose and to rely as much as possible on lifestyle and dietary measures rather than medications.^[8]

Side effects from constipation treatments vary by the type of medication used. Fiber supplements can cause gas and bloating, especially when first started. Osmotic laxatives may cause diarrhea if too much is taken, along with abdominal cramping. Stimulant laxatives often produce cramping and can lead to dependence if used regularly. The newer prescription medications can cause diarrhea, abdominal pain, and nausea in some individuals.^[10]

Clinical guidelines emphasize the importance of identifying and addressing any underlying causes of constipation. Certain medications, including some pain relievers containing codeine or oxycodone, antidepressants, antacids with calcium or aluminum, iron supplements, and some blood pressure medications, can cause or worsen constipation. When medication-induced constipation is suspected, doctors may adjust dosages or switch to alternative medications that don’t have this side effect.^[11]

For individuals whose constipation is related to pelvic floor dysfunction—a condition where the muscles involved in having a bowel movement don’t work properly—specialized treatment called pelvic floor therapy with biofeedback may be recommended. This approach involves working with a trained therapist who uses sensors and computer feedback to help retrain the pelvic floor muscles. Studies have shown this therapy to be more effective than laxatives alone for people with defecatory dysfunction, which is difficulty with the actual process of passing stool.^[12]

Emerging Therapies in Clinical Research

While standard treatments work well for many people, researchers continue to investigate new approaches for those who don’t respond adequately to conventional options. Clinical trials are ongoing to test innovative therapies that work through different mechanisms than currently available treatments.^[4]

Some clinical trials are examining how certain probiotics—beneficial bacteria that live in the gut—might help with constipation. The theory is that these organisms could help improve the overall function of the digestive system and promote more regular bowel movements. However, research in this area is still in relatively early stages, and more studies are needed to determine which specific strains of probiotics are most effective and what doses work best.^[2]

Researchers are also exploring medications that target specific receptors or pathways in the digestive system. These novel compounds aim to stimulate intestinal movement or increase fluid secretion through different mechanisms than existing drugs. Some are being tested to see if they can provide relief with fewer side effects or work better for people who haven’t responded to other treatments.^[4]

Clinical trials typically progress through three main phases. Phase I trials focus primarily on safety, testing new treatments in small groups of people to see if they cause any serious side effects and to determine appropriate dosing. Phase II trials involve larger groups and aim to see if the treatment actually works—does it improve symptoms of constipation? Phase III trials compare the new treatment directly with standard therapies to see if it offers any advantages in terms of effectiveness or side effects.^[4]

Some clinical studies are investigating whether certain dietary interventions beyond simple fiber supplementation might help. These include specific combinations of foods, particular types of prebiotics (substances that feed beneficial gut bacteria), or specialized nutritional formulas designed to promote better bowel function. The goal is to find dietary approaches that are more effective than current recommendations while still being practical for people to follow in their daily lives.^[2]

In cases of severe constipation that doesn’t respond to any medical treatment, researchers are studying surgical options. These procedures might involve removing part of the colon that isn’t functioning properly or performing operations to correct structural problems that contribute to constipation. However, surgery is reserved only for very select cases where all other treatments have failed and where specific anatomical problems have been clearly identified through specialized testing.^[12]

Clinical trials for constipation treatments are being conducted in many locations around the world, including the United States, Europe, and other regions. Eligibility to participate typically depends on factors such as the type and severity of constipation, age, other medical conditions, and current medications. People interested in participating in research studies can ask their doctors about available trials or search clinical trial registries to find studies that might be appropriate for them.^[3]
