Understanding Your Digestive System’s Signals
Your digestive system does much more than break down food. It can provide important clues about your overall health. Common symptoms like bloating, constipation, diarrhea or food sensitivities may be signaling deeper issues that go beyond your gut.
Common digestive symptoms
While occasional discomfort is normal, persistent or worsening symptoms should be discussed with a healthcare provider. Some of the most common may include:
- Bloating and gas – often linked to diet, food intolerances or changes in gut bacteria.
- Constipation – typically determined by fewer than three bowel movements per week, it affects many adults.
- Diarrhea – frequent loose stools, may be related to infections, food triggers or chronic conditions.
- Food sensitivities – reactions to specific foods that can cause discomfort or inflammation.
According to a study conducted by the National Institutes of Health, 61% of the participants reported having one or more gastrointestinal symptoms within their week. Abdominal pain, bloating, diarrhea and constipation were among the most common.
When symptoms point to something more
Chronic digestive issues can signal underlying conditions such as:
- Irritable Bowel Syndrome (IBS) – affects an estimated 10-15% of US adults, with only 5-7% of them receiving a diagnosis.*
- Celiac disease – an immune reaction to gluten that damages the small intestine lining.
- Inflammatory Bowel Disease (IBD) – chronic inflammation of the digestive tract, including Crohn’s disease and ulcerative colitis.
The gut-brain-immune connection
The gut and brain communicate constantly through what’s known as the gut-brain axis. This link means digestive health can affect:
- Mental health – stress and anxiety can worsen gut symptoms, while gut inflammation may influence mood.
- Immune health – about 70% of the immune system resides in the gut, making it a key player in defending against illness.**
- Inflammation – imbalances in gut bacteria can trigger immune responses and systemic inflammation.
From nutrient absorption to immune defense, your gut plays a central role in your health. Listening to its signals (and acting on them) can help prevent complications and support your future wellness.
