Bloating, gas, constipation? Harvard-trained gut doctor shares 8 everyday habits quietly causing poor digestion

Your gut health is shaped by far more than what lands on your plate. Everyday routines, from distracted eating and irregular meals to constantly reaching for snacks or delaying a bathroom break, can influence digestion, bowel regularity and how comfortably your body processes food. Some habits may appear harmless because they are repeated every day without a second thought, while others can gradually become problematic when they turn into patterns. Harvard-trained gut doctor Saurabh Sethi has now shared eight everyday habits he says people should reconsider for better gut health.

Eating while scrolling

Multitasking during meals can make it harder to pay attention to hunger and fullness cues. Dr Sethi says eating while distracted, such as scrolling on your phone, can encourage overeating. Putting the screen away can help make meals more mindful.

Randomly skipping meals

Skipping a meal occasionally is not necessarily harmful, but Dr Sethi distinguishes structured intermittent fasting from randomly missing meals because of stress or a hectic schedule. Maintaining a more consistent eating routine may be preferable to erratic meal timing.

Ending every meal with something sweet

A dessert after every meal can turn into a habitual sugar hit. Dr Sethi cautions against making something sweet an automatic part of every meal, particularly when overall added-sugar intake is high. Rather than blaming specific gut bacteria, the broader goal is to avoid unnecessary, repetitive sugar consumption.

Taking ibuprofen for every headache

Frequently taking ibuprofen or other NSAIDs without a clear need can irritate the gastrointestinal tract. These medicines can affect the stomach and intestinal lining, making regular or excessive use something to discuss with a healthcare professional.

Drinking most water at night

Saving most of your water intake for bedtime is not an ideal hydration strategy. Dr Sethi recommends drinking fluids consistently throughout the day instead of trying to compensate at night. Adequate hydration is also important for maintaining comfortable bowel movements.

Ignoring the urge to use the bathroom

Repeatedly postponing a bowel movement can contribute to constipation and disrupt regular bowel habits. Dr Sethi recommends listening to the body's signals rather than routinely ignoring the urge to go.

Snacking constantly between meals

Constant grazing leaves little fasting time between eating occasions. The migrating motor complex, a recurring pattern of movement in the stomach and small intestine, occurs during fasting and is interrupted by eating.

Eating close to bedtime

Late-night eating can affect digestion and may also interfere with sleep. Dr Sethi recommends leaving some time between the final meal and bedtime instead of routinely eating immediately before turning in.
