Dietary fiber plays a crucial role in managing chronic constipation, a condition marked by infrequent, hard, and painful bowel movements. This case study explores how increasing dietary fiber can alleviate symptoms of chronic constipation. By examining the diet and lifestyle changes of Harish, a 23-year-old engineering student, we illustrate the positive impact of fiber-rich foods and supplements in promoting regular bowel movements and improving digestive health.
CASE STUDY:
Harish, a 23-year-old engineering student, resides in a hostel where he consumes a diet primarily consisting of non-vegetarian and maida-based foods provided by the hostel mess. His diet lacks adequate fruits and vegetables, which are essential for maintaining digestive health. Harish began experiencing severe constipation, which led to mild bleeding from the anal region, prompting concern and medical intervention.
Clinical Presentation:
Harish's symptoms included:
Infrequent bowel movements (less than three times per week)
Hard, lumpy stools
Straining during bowel movements
Sensation of incomplete evacuation
Mild rectal bleeding, likely due to anal fissures or haemorrhoids caused by the strain of passing hard stools.
Consultation and Diagnosis:
Harish's father, a diabetic patient under the care of Dr. Anirban Biswas, brought him to the clinic for evaluation. After a thorough examination and history taking, Dr. Biswas diagnosed Harish with chronic constipation, a common gastrointestinal condition characterized by difficult, infrequent, or perceived incomplete evacuation of bowel movements.
What is Chronic Constipation?
Chronic constipation is a condition characterized by infrequent, difficult, or painful bowel movements lasting several weeks or longer. It often involves hard, dry stools and a sensation of incomplete evacuation.
Chronic constipation is a prevalent condition that can significantly impact an individual's quality of life. It is often multifactorial, with dietary habits playing a crucial role. Harish's diet, lacking in fibre-rich foods such as fruits, vegetables, and whole grains, significantly contributes to his condition. Fibre is essential for adding bulk to the stool and promoting regular bowel movements. A diet high in processed foods and low in dietary fibre can lead to hard stools and difficulty in passing them.
Management and Treatment:
Dr. Biswas recommended the following interventions for Harish:
Increase intake of high-fibre foods such as fruits (e.g., apples, pears, berries), vegetables (e.g., spinach, carrots, broccoli), whole grains (e.g., oats, brown rice), and legumes (e.g., beans, lentils).
Incorporate fibre-rich cereals and nuts into his breakfast routine.
Ensure adequate hydration by drinking plenty of water, as fibre works best when it absorbs water, making the stool soft and easier to pass.
2. Isabgol Powder (Psyllium Husk):
Dr. Biswas suggested the use of isabgol powder, a natural fibre supplement, to be taken with water. Isabgol is known for its high fibre content, which helps in forming a gel-like substance in the intestines, aiding in smoother bowel movements.
3. Lifestyle Changes:
Encourage regular physical activity, which helps stimulate intestinal function.
Establish a routine for bowel movements, preferably after meals when the body’s natural gastrocolic reflex is most active.
Avoid prolonged holding of bowel movements, which can exacerbate constipation.
Outcome:
Following Dr. Biswas's recommendations, Harish made significant changes to his diet and lifestyle. He started incorporating more fibre-rich foods into his meals and consistently used isabgol powder as advised. Over a few weeks, he experienced noticeable improvements in his bowel habits. The frequency of his bowel movements increased, the consistency of his stools softened, and the rectal bleeding subsided.
To conclude, Harish's case highlights the importance of a balanced diet rich in fibre for the prevention and management of chronic constipation. Adequate hydration, regular physical activity, and timely medical consultation are critical components in addressing this common yet often overlooked condition. Through dietary modifications and the use of fibre supplements, individuals suffering from chronic constipation can achieve significant relief and improved quality of life.
Chronic Constipation: Treatment Options

Bowel Routine: Establish a regular time for bowel movements, preferably after meals.
Avoid Holding Bowel Movements: Respond promptly to the urge to defecate.
6. Medications:
Prescription Medications: Lubiprostone, linaclotide, and prucalopride for severe cases.
Over-the-Counter Options: Depending on the severity and patient response.
7. Behavioural Therapies:
Biofeedback Therapy: For those with pelvic floor dysfunction contributing to constipation.
8. Surgical Options:
Surgery: Rarely recommended, but may be necessary for severe, refractory cases.

10 Foods That May Cause or Worsen Constipation
Refined Grains: Low-fiber foods like white bread, pizza dough, cakes, and other baked goods made with refined flour can contribute to constipation.
Processed & Frozen Foods : Processed foods can cause constipation due to their low fiber and high salt content
Salty Snacks: Chips, kurkure, mixtures and other salty snacks often lack fiber and can exacerbate constipation.
Bananas: Particularly unripe bananas can be binding and might worsen constipation.
Milk and Dairy Products: Dairy can be constipating for many people, especially those who are lactose intolerant or consume it in large quantities.
Red Meat: Red meat can cause constipation due to its high fat and protein content, which can slow digestion.
Fried and Fast Foods: These are low in fiber and high in fat and salt, which can slow down digestion and exacerbate constipation.
Caffeine: By increasing fluid loss through urine and reducing gut contractions, caffeine can contribute to constipation.
Chocolate: Its high-fat content can slow digestion and worsen constipation symptoms.
Supplements: Some Iron and calcium supplements may cause constipation in some people, particularly if not paired with fiber-rich foods.
