- Regular bowel movements are essential for overall health and support proper digestion.
- Simple habits like hydration, fiber intake, coffee, physical activity, and proper posture can help stimulate bowel movements.
- Consistency in daily routines and a gut-healthy diet can improve long-term digestive health.
Regular bowel movements are a hallmark of good health. A well-functioning digestive system allows your body to eliminate waste and toxins. When bowel movements are delayed, your colon continues to absorb water, making stool harder and more painful to pass, David Kahana, MD, a board certified gastroenterologist and 1MD Nutrition physician formulator, told Health. Chronic irregularity can lead to increased inflammation, metabolic dysfunction, hemorrhoids, or impaction.
1. Hydrate With Warm Water and Lemon
You're usually mildly dehydrated when you wake up; drinking 8 to 12 ounces of water helps signal to the colon to contract (peristalsis). "I often recommend adding lemon to stimulate bile production, which aids in lipid digestion and further prompts the bowels to move."
Some research has also shown that drinking warm water can speed up your body’s temperature regulation and help you have a bowel movement more quickly.
2. Prioritize a High Fiber Diet
A high-fiber breakfast featuring prebiotic foods, such as oatmeal with kiwi, berries, or prunes, can help promote a morning bowel movement.
"Fiber increases stool bulk, accelerates transit time, and nourishes beneficial bacteria as prebiotics," Sabine Hazan, MD, a gastroenterologist, CEO of Ventura Clinical Trials, and founder of ProgenaBiome, told Health.
3. Leverage the Power of Coffee
Many people already rely on their morning cup of joe, but there is also significant clinical data behind it. A landmark study found that caffeinated coffee induces a gastrocolic response that is 60% more effective than plain hot water and 23% stronger than decaffeinated coffee.
The study found that coffee’s effect on the colon is equal to consuming a 1,000-calorie meal. "This means coffee provides a massive biochemical wake-up call to your intestines without the heavy caloric load," said Kahana. "[In other words,] coffee primes the pump for your first movement of the day."
4. Try the Squat Position
"Using a foot stool to elevate your knees above your hips mimics a natural squatting position, straightening the anorectal angle and allowing for an easier, more complete bowel evacuation," said Kahana.
In fact, researchers have found that squatting reduces digestive strain and promotes an easier bowel movement. This position is especially beneficial if you have constipation. That said, for some people, like older adults, sitting may be more comfortable.
5. Stay Physically Active
A morning walk can help trigger bowel movements, as the body naturally releases hormones that help purge toxins.
"A morning walk or light exercise can make all the difference in the world when it comes to triggering a bowel movement," said Kahana. However, exercise at any time of the day will help the bowel propagate stool. "Just make sure to hydrate with electrolytes, especially magnesium-containing liquids, to avoid dehydrating the stool," he added.
6. Use Targeted Supplementation
Probiotics can also help trigger a bowel movement in the morning, said Kahana. "Taking a probiotic in the morning helps seed the gut with beneficial bacteria like Bifidobacterium and Lactobacillus, which produce short-chain fatty acids that naturally stimulate intestinal motility."
One study in particular found that probiotics increased gut transit time by 12.4 hours. Their use also increased the number of weekly bowel movements by 1.3 and softened stools, making it easier for people to pass stool.
7. Use the Bathroom at the Same Time Every Day
Sitting on the toilet at the same time every day, typically after breakfast, trains your body to respond to your body's morning gastrocolic reflex, said Hazan. This practice reduces straining and prevents waste from lingering, which helps sustain your microbiome health.
"Like your body’s circadian rhythms, the gut operates on its own daily clock, helping stabilize motility, microbial composition, and the gut-brain axis," he said.
