Constipation is characterized by infrequent bowel movements (typically fewer than three per week), hard or lumpy stools, and difficulty or straining during bowel movements. It is one of the most common digestive complaints and is often linked to diet, hydration, and activity levels. Most constipation is temporary and responds well to lifestyle modifications.
Constipation is one of the most prevalent digestive complaints, affecting about 16% of adults regularly and up to 33% of adults over 60. While bowel habits vary widely from person to person — anywhere from three times daily to three times weekly can be normal — constipation is typically defined as having fewer than three bowel movements per week, especially when stools are hard, dry, or difficult to pass.
The colon's job is to absorb water from digested food as it passes through. When food moves too slowly through the digestive tract, the colon absorbs more water than needed, resulting in hard, dry stools that are difficult and sometimes painful to pass. This slow transit can be caused by dietary factors, dehydration, lack of physical activity, certain medications, or changes in routine.
Most constipation responds well to simple lifestyle changes such as increasing fiber intake, drinking more water, and exercising regularly. These measures work by adding bulk to stools, keeping them soft, and stimulating the natural contractions of the intestines. When lifestyle changes are not enough, a variety of safe over-the-counter options are available, and a healthcare provider can help identify any underlying causes.
There are several possible reasons you may be experiencing Constipation. Here are the most common ones.
A diet lacking in fruits, vegetables, whole grains, and legumes does not provide enough bulk to form soft, well-formed stools. The average adult consumes only about 15 grams of fiber daily, far less than the recommended 25-30 grams.
Water is essential for keeping stools soft and easy to pass. When the body is not getting enough fluids, the colon compensates by absorbing more water from digested food, resulting in harder stools.
Physical inactivity slows down the natural contractions (peristalsis) that move food through the digestive tract. Prolonged sitting, bed rest, and lack of regular exercise are common contributors to constipation.
Many commonly used medications can cause constipation, including opioid pain relievers, iron supplements, calcium-containing antacids, certain blood pressure medications, and some antidepressants.
Repeatedly ignoring or delaying the urge to have a bowel movement can weaken the signals over time and contribute to constipation. This is common in people with busy schedules or who are uncomfortable using public restrooms.
The constipation-predominant form of IBS causes infrequent bowel movements along with abdominal cramping and bloating. IBS involves altered communication between the brain and gut, affecting motility patterns.
An underactive thyroid slows many body functions, including digestive transit. Constipation is a common symptom of hypothyroidism and usually improves with thyroid hormone replacement therapy.
These approaches may help manage constipation at home. Always consult a healthcare provider if symptoms persist or worsen.
Aim for 25-30 grams of fiber daily from foods like whole grains, fruits (especially prunes, kiwis, and berries), vegetables, beans, and lentils. Increase fiber intake gradually over 2-3 weeks to avoid gas and bloating.
Aim for at least 8 glasses of water daily. Warm water first thing in the morning can stimulate bowel activity. Adequate hydration works synergistically with fiber to keep stools soft and easy to pass.
Even a daily 20-30 minute walk can significantly improve bowel regularity. Physical activity stimulates the muscles of the intestines and promotes natural peristalsis, helping move stools through the colon more efficiently.
Prunes contain sorbitol, a natural sugar alcohol that draws water into the intestines and has a mild laxative effect. Eating 5-6 prunes or drinking a glass of prune juice daily is an evidence-based remedy for constipation.
The colon is naturally most active after waking and after meals. Try sitting on the toilet for 5-10 minutes after breakfast, even if you do not feel a strong urge. Using a footstool to elevate the knees above the hips can also help by straightening the anorectal angle.
Doctors evaluate constipation by asking about bowel habits, diet, fluid intake, medications, and exercise levels. A physical examination may include a digital rectal exam to assess stool consistency and rectal muscle tone. Blood tests can check for thyroid disorders, calcium levels, and other metabolic causes. If red flag symptoms are present (blood in stool, weight loss, new onset over age 50), a colonoscopy may be recommended. For chronic constipation not responding to initial treatments, specialized tests such as colonic transit studies, anorectal manometry, or defecography may assess how well the colon and pelvic floor muscles are functioning.
Consult a doctor if constipation is new and unexplained (especially after age 50), is accompanied by blood in the stool, significant abdominal pain, or unintentional weight loss, or if it persists despite increasing fiber and fluids. A sudden change in bowel habits that lasts more than two weeks deserves evaluation.
Steps you can take to reduce the likelihood of experiencing constipation.
Eat a diet rich in fiber from whole grains, fruits, vegetables, and legumes (aim for 25-30 grams daily)
Drink at least 8 glasses of water daily and more during exercise or hot weather
Stay physically active with regular exercise like walking, swimming, or cycling
Respond promptly to the urge to have a bowel movement — do not delay
Review medications with your doctor if you notice constipation developing as a side effect
There is no single 'normal' frequency for bowel movements. Anywhere from three times a day to three times a week falls within the normal range. What matters more than frequency is consistency — stools should be soft, well-formed, and easy to pass. If your pattern changes significantly or if you experience straining, hard stools, or a feeling of incomplete evacuation, you may be constipated.
Bulk-forming laxatives (fiber supplements like psyllium) and osmotic laxatives (like polyethylene glycol/MiraLAX) are generally safe for regular use under medical guidance. Stimulant laxatives (like bisacodyl or senna) are best used occasionally and not as a long-term solution, as the bowel can become dependent on them. If you find yourself needing laxatives frequently, consult a healthcare provider to address the underlying cause.
Chronic constipation can lead to complications including hemorrhoids (from straining), anal fissures (small tears in the skin around the anus), fecal impaction (hardened stool that cannot be passed), and rectal prolapse (in severe cases). Chronic straining may also contribute to pelvic floor weakness. Addressing constipation early with lifestyle changes prevents most of these complications.
Research shows that a squatting position, with knees elevated above the hips, straightens the anorectal angle and makes bowel movements easier and more complete. You can achieve this by using a small footstool (about 7-9 inches high) to raise your feet while sitting on the toilet. Lean forward slightly with your elbows on your knees. This simple change can make a noticeable difference.
