Gastroenterologist Publishes Evidence-Based Guidelines for Digestive Health

A gastroenterologist has published a series of evidence-based recommendations aimed at improving digestive health and bowel habits. The guidelines, which cover diet, behavior, and posture, are based on clinical experience and research.

Background and Context

Dr. Trisha Pasricha, director of the Institute for Gut-Brain Research at Beth Israel Deaconess Medical Center and an assistant professor at Harvard Medical School, has compiled these recommendations. According to the American Gastroenterological Association, approximately 40% of Americans experience bowel symptoms that affect daily life. Dr. Pasricha treats patients with conditions like irritable bowel syndrome (IBS) and has detailed these practices in a book.

Observing Bowel Health

Dr. Pasricha states that observing stool characteristics can provide health information.

Normal bowel movement frequency is reported to range from three times daily to three times weekly.

• Stool that is very hard and lumpy or watery in consistency may indicate issues.
• Stool that is black, whitish, red, or maroon in color may require medical evaluation, as red or maroon stool could indicate bleeding or reflect the consumption of certain foods like beets.

Dietary Recommendations

The recommendations emphasize specific dietary adjustments for digestive function.

• Fiber: Increased fiber consumption is recommended, as it can help manage both diarrhea and constipation. Fiber serves as food for colon microbes, which produce short-chain fatty acids. Research has associated these fatty acids with reduced inflammation and lower risks of colon cancer, heart attack, and dementia.
• Psyllium: Psyllium supplements are suggested for individuals with insufficient dietary fiber intake.
• Spices: Moderate consumption of spices, including hot peppers, mustard, oregano, garlic, and horseradish, may help maintain regularity.

• Ultra-Processed Foods: Research indicates that some additives and emulsifiers in ultra-processed foods may affect the gut's mucus barrier and microbial composition. A cited study of over 200,000 participants found that those who consumed more ultra-processed foods had a 20% higher likelihood of irritable bowel syndrome.
• Artificial Sweeteners: Artificial sweeteners are noted to cause diarrhea and bloating.

Behavioral and Habit-Based Recommendations

Guidelines also address time spent on the toilet and device use.

Limiting toilet sitting time to five minutes or less is recommended. Extended sitting may increase the risk of hemorrhoids by weakening connective tissue around rectal veins.

• If a bowel movement does not occur within five minutes, it is suggested to get up and take a movement break.
• Physical activity, including brisk walking, can stimulate bowel contractions.

• A survey of 125 people conducted by Dr. Pasricha's research team found that those who reported using smartphones on the toilet were 46% more likely to have hemorrhoids than those who did not. Smartphone users were also five times more likely to spend over five minutes in the bathroom.
• It is noted that stress from social media use may affect the relaxation of pelvic floor muscles.
• For bathroom reading, light print material like comic books or short magazine articles is suggested. If using a phone, a limit such as "two TikToks" is recommended before reassessing.

Physical Positioning

Posture during bowel movements is also addressed.

• Using a stool or yoga blocks to elevate the knees higher than the hips while seated on a toilet can help relax a key pelvic muscle and straighten the colon.
• Leaning forward with elbows on knees, a posture similar to that in Auguste Rodin's sculpture "The Thinker," may further optimize the bowel angle for evacuation.

Additional Notes

Dr. Pasricha notes that digestive health can change with age, lifestyle shifts, and other factors, and recommends consulting a healthcare professional if concerns arise.
