Digestive health: symptoms, causes and solutions

Understanding constipation and its impact on digestion

Constipation digestive disorder , particularly during periods of dietary or lifestyle changes.

Physiologically, constipation is often linked to a slowing of intestinal transit , excessive water absorption by the colon, or decreased digestive motility. A diet low in fiber, insufficient hydration, chronic stress, or certain medications can disrupt the natural balance of digestion .

The recommended approaches are based on gradual adjustments: increasing dietary fiber, regular physical activity, and supporting the gut microbiota. Soluble fibers such as psyllium are frequently studied for their role in regulating bowel movements.

Intestinal bloating and digestive fermentation

Bloating refers to an excessive accumulation of gas in the digestive system, often felt as abdominal distension. It is among the most common disorders of functional digestion .

From a digestive standpoint, bloating is often linked to intestinal fermentation, particularly during the digestion of certain fermentable carbohydrates (FODMAPs). Insufficient chewing, incomplete enzymatic digestion, or intestinal hypersensitivity can exacerbate these symptoms.

Current recommendations emphasize identifying trigger foods, reducing stress, and supporting digestion with carminative herbs or targeted probiotics.

The content below provides a clear and scientific explanation of the causes and solutions of bloating .

Accelerated transit and digestive imbalance

Diarrhea is defined as an increase in the frequency of bowel movements associated with a liquid consistency. It most often reflects an acceleration of intestinal transit , which prevents normal water absorption in the intestines.

The most frequent causes include digestive infections, food intolerances, acute stress, or imbalances in the gut microbiota. In these situations, digestion is disrupted either temporarily or chronically.

The recommendations are based on preventing dehydration, protecting the intestinal lining, and gradually restoring digestive balance. Certain specific probiotics have been the subject of clinical studies in this context.

Acid reflux and upper digestive tract

Gastroesophageal reflux disease ( GERD) is a common upper digestive characterized by the backflow of acidic stomach contents into the esophagus. It manifests as heartburn, regurgitation, or discomfort after meals.

Mechanically, GERD is often linked to a dysfunction of the lower esophageal sphincter or to slowed gastric digestion . Certain dietary and postural factors can worsen the symptoms.

Management strategies rely on lifestyle modifications, a suitable diet, and, in some cases, medical support. A better understanding of the mechanisms of reflux allows for lasting improvements in digestion .

Feeling of heaviness and inefficient digestion

Slow digestion manifests as a prolonged feeling of heaviness after meals, bloating, or postprandial fatigue. It often reflects a decrease in digestive or enzymatic activity.

Contributing factors include chronic stress, overly rich or unbalanced meals, and a lack of exercise. Inefficient digestion can also limit optimal nutrient absorption.

Natural approaches favor a more digestible diet, the use of bitter herbs, and the improvement of overall digestive rhythm.

The accompanying guides help to gently stimulate digestion , without disrupting the gut balance.

Intestinal hypersensitivity and functional digestion

Irritable bowel syndrome ( IBS) is a functional digestive disorder characterized by recurrent abdominal pain associated with bowel movement irregularities, without any detectable organic abnormality.

Current research highlights the role of the gut-brain axis, stress, and the microbiota in the development of symptoms. Digestion then becomes particularly sensitive to certain foods or emotional situations.

The treatment is based on an individualized approach combining adapted diet, stress management and support of the intestinal flora.
