Your gut signals matter: What your digestive system is trying to tell you
Your gut isn’t just about digestion — it’s a powerful messenger. According to Dr Joseph Salhab, a board-certified gastroenterologist and content creator known online as @thestomachdoc, your digestive system constantly communicates about how you eat, how you live, and how you feel.
Understanding gut signals
Your digestive system generates feedback through symptoms like bloating, excess gas, abdominal cramping, changes in bowel habits (constipation, diarrhea, or urgency), reflux or heartburn, early fullness, nausea or a general “off” feeling. Many of these episodes are harmless and triggered by stress, infections, the menstrual cycle, travel, certain medications or eating too many ultra-processed foods.
What your “gut feeling” really means
Dr Salhab explains that what people call a gut instinct has real biology behind it. “The enteric nervous system (your gut’s built-in nerve network), the vagus nerve, immune signals, hormones and the microbiome are constantly messaging the brain in a two-way conversation.” Healthline This gut-brain connection helps explain why stress may cause nausea or why anxiety might trigger stomach-knots.
Symptoms you should not ignore
While occasional digestive upset is common, some signs merit medical attention:
- Chronic bloating or gas, iron-deficiency anaemia, frequent heartburn that doesn’t respond to antacids, unintentional weight changes, new food intolerances or alternating constipation and diarrhoea.
- Gut symptoms paired with mouth ulcers, joint pains, skin rashes or eye irritation might suggest a condition like inflammatory bowel disease (IBD).
Daily habits that support gut-health
Dr Salhab emphasises that this is not about quick fixes or cleanses — the most effective approach is steady, everyday habits:
- Drink enough water, limit alcohol and focus on balanced meals with protein, colours and fermentable fibres.
- Aim for a variety of plants — legumes, nuts, seeds, whole grains and vegetables — to feed your gut microbes.
- Prioritise regular movement, 7-9 hours of sleep and stress-management practices like breathwork or mindfulness.
These habits help your gut “train” quietly over time, creating a resilient foundation that outperforms any short-term diet or supplement.
