Chronic Constipation: Symptoms, Causes & Treatment

Chronic constipation is a common condition defined as infrequent or difficult bowel movements lasting three months or longer. Patients experience hard, dry stools, incomplete evacuation sensation, or the need for excessive straining during bowel movements. This condition affects millions worldwide and increases with age, particularly in women and people over 60 years old.

Chronic constipation occurs when waste moves slowly through the colon and rectum, allowing excessive water absorption and resulting in harder stools. The cause may be lifestyle-related (sedentary behavior, low water intake, insufficient fiber intake), weak bowel habits, or other medical conditions. In Gulf and Middle Eastern countries including Jordan, chronic constipation is often linked to modern lifestyles, reduced physical activity, and imbalanced nutrition.

Although chronic constipation is rarely serious on its own, it may lead to complications if left untreated for extended periods. Diagnosis begins with medical history and physical examination, and additional testing may be necessary. Treatment depends on the underlying cause and ranges from lifestyle modifications to laxatives and specialized medications.

Symptoms of chronic constipation vary among individuals and may be mild or severe, affecting quality of life. Main symptoms include:

• Infrequent bowel movements: Fewer than 3 bowel movements per week, sometimes reducing to once weekly.
• Hard, dry stools: Stools are firm and difficult to pass, requiring excessive straining.
• Straining and pain during defecation: Discomfort ranging from mild to severe pain in the lower abdomen and rectum.
• Sensation of incomplete evacuation: Feeling that stool remains even after bowel movement.
• Bloating and gas: Gas accumulation in the intestines due to slow transit.
• Abdominal discomfort and pain: Mild to moderate pain in the abdomen and colon.
• Loss of appetite: Some patients experience reduced hunger due to fullness and bloating.
• Fatigue and tiredness: General exhaustion and lethargy may accompany severe chronic constipation.
• Light rectal bleeding: Mild bleeding from the rectum when straining (from hemorrhoids or anal fissures).

• Low dietary fiber: Modern diet rich in processed foods lacking vegetables and whole grains reduces fiber intake, which helps soften stool and promote intestinal movement.
• Insufficient water intake: Dehydration causes dry, hard stool that is difficult to pass; water is essential for stool softening and normal bowel movement.
• Sedentary lifestyle and lack of exercise: Prolonged sitting and inactivity weaken abdominal and colon muscles, slowing intestinal movement.
• Medications: Certain drugs including opioid pain relievers, blood pressure medications, antidepressants, and iron supplements may cause constipation as a side effect.
• Ignoring the urge to defecate: Repeatedly delaying bowel movements weakens nerve signals and reduces intestinal motility over time.
• Irritable bowel syndrome: Some types of IBS present with chronic constipation due to heightened intestinal sensitivity.
• Muscle and nerve problems: Conditions affecting the nerves and muscles controlling intestinal movement such as Alzheimer's disease or paralysis.
• Hormonal disorders: Thyroid insufficiency, diabetes, and hormonal imbalances slow intestinal motility.

• Advanced age: Constipation risk increases significantly after age 60 due to weakened digestive muscles and nerve changes.
• Female gender: Women are 2-3 times more likely to experience chronic constipation than men, especially during pregnancy and menstrual cycles.
• Pregnancy: Hormonal changes and mechanical pressure from the fetus on the intestines increase constipation risk.
• Chronic diseases: Patients with diabetes, thyroid insufficiency, arthritis, and stroke history face higher constipation risk.
• Frequent laxative use: Long-term laxative dependence reduces the intestines' natural response and may worsen the problem.
• Psychological stress and anxiety: Stress and depression affect intestinal motility and can cause or worsen constipation.
• Sedentary lifestyle: People with jobs requiring prolonged sitting are more susceptible to constipation.
• Family history: Having family members with chronic constipation may increase risk.
• Poor nutrition: Deficiency of minerals and vitamins may affect digestive health.
• Chronic dehydration: People who do not drink sufficient fluids daily face higher constipation risk.

Diagnosis of chronic constipation relies on detailed medical history and physical examination, with specialized tests used in complex cases. The physician will ask about bowel habits, duration of symptoms, type of stools, medications used, and other medical conditions.

• Physical examination: Abdominal examination to check for bloating and pain, and digital rectal examination (inserting a gloved finger into the rectum) to assess for fecal impaction or other issues.
• Blood tests: Measuring thyroid function, blood sugar, minerals, and vitamins to detect other medical conditions causing constipation.
• Additional imaging: In complex cases, the doctor may order abdominal X-rays or CT scans to exclude obstruction or structural problems.
• Colonic Transit Study: In rare cases, this test measures how quickly contents move through the colon.
• Sigmoidoscopy or full colonoscopy: In certain cases, the physician may request endoscopic examination of the colon to rule out tumors or inflammation.

Medications

• Osmotic Laxatives: Such as polyethylene glycol (PEG) and lactulose, which draw water into stool to soften it. Safe for long-term use and considered first-line therapy.
• Stimulant Laxatives: Such as bisacodyl and senna, which stimulate intestinal muscle contractions. Should be used cautiously and not long-term to avoid dependence.
• Stool Softeners: Such as docusate sodium, which adds moisture to stool for easier passage.
• Specialized Modern Medications: Such as linaclotide and prucalopride, which improve intestinal motility and are used for complex cases.
• Fiber Supplements: Such as psyllium and methylcellulose, which increase fiber content and improve bowel movement.

Procedures and Other Interventions

• Sacral Nerve Stimulation: A relatively modern procedure involving implantation of a small device sending electrical pulses to improve intestinal movement in severe, treatment-resistant cases.
• Enemas and Rectal Irrigation: Enemas may be used in acute cases to speed up bowel movements, but should not be relied upon regularly.
• Surgical Intervention: In very rare cases of severe, treatment-resistant chronic constipation, surgery to remove part of the colon may be recommended.

Lifestyle Changes

• Increase dietary fiber intake: Gradually consume vegetables, fruits, whole grains, and legumes (aiming for 25-35g daily) while increasing water intake.
• Drink adequate water and fluids: At least 8-10 cups of water daily, with more needed based on activity level and weather.
• Regular physical activity and exercise: Brisk walking, swimming, or yoga for 30 minutes daily, as movement improves intestinal motility.
• Establish regular bowel habits: Try using the bathroom at the same time daily, especially after waking or after meals.
• Do not ignore the urge to defecate: Respond immediately to body signals and use the bathroom as soon as the need arises.
• Reduce constipation-causing foods: Limit white rice, white flour, fast food, and fatty foods.
• Manage psychological stress: Practice relaxation techniques, meditation, and get adequate sleep (7-8 hours daily).
• Reduce caffeine and alcohol: These may increase dehydration and worsen constipation.

• Hemorrhoids: Repeated straining during bowel movements may cause enlargement of blood vessels in the rectum and anus, leading to bleeding, pain, and itching.
• Anal Fissures: Small tears in the anal tissue resulting from hard stool and straining, causing severe pain during and after bowel movements.
• Fecal Impaction: Accumulation of hard, dry stool in the intestines may cause complete obstruction in severe cases, requiring emergency medical intervention.
• Rectal Prolapse: Chronic straining may cause part of the rectum to protrude from the anus, a rare but treatable condition.
• Acute Hemorrhoids and Continuous Bleeding: Persistent bleeding may lead to anemia and general weakness.
• Nutrient Malabsorption: In cases of very severe and chronic constipation, absorption of certain minerals and vitamins may be affected.
• Chronic Bloating and Gas: May cause psychological and social discomfort and embarrassment.

• Consume adequate daily fiber: Aim for 25-35 grams daily from vegetables, fruits, whole grains, and legumes.
• Drink sufficient water and fluids: Consume at least 8-10 cups of water daily, more if you are physically active or live in a hot climate.
• Regular physical activity and exercise: Engage in 30 minutes of moderate physical activity daily such as brisk walking or swimming.
• Respond immediately to body signals: Do not delay going to the bathroom when you feel the urge; go immediately at the first sensation of needing to defecate.
• Establish regular bowel habits: Try to use the bathroom at the same time each day to promote regular habits.
• Limit constipation-causing foods: Reduce white rice, white flour, fast food, and fatty foods.
• Avoid psychological stress and anxiety: Practice relaxation techniques, mindfulness, and get adequate sleep.
• Reduce caffeine and alcohol intake: Limit coffee, tea, soft drinks, and alcohol as they may increase dehydration.
• Maintain a healthy weight: Obesity increases constipation risk; maintain physical activity and balanced diet.
• Regular doctor consultations: If you take medications that may cause constipation, discuss alternative options with your physician.
