How do you Know if your Body isn't Digesting Food Properly?

Gastrointestinal symptoms offer important clues about how well your digestive system is functioning. The type and timing of these symptoms can also indicate which organ or part of the digestive tract may be affected.

Bloating
Bloating is often a sign of low stomach acid (hydrochloric acid). If you experience bloating within an hour after eating, it suggests that your stomach isn't producing enough hydrochloric acid to break down food properly. However, if bloating occurs more than an hour after eating, this indicates a deficiency in pancreatic enzymes. This is because, around one hour after eating, the partially digested food (chyme) moves into the duodenum, where pancreatic enzymes are released to continue digestion.

Issues in the Small Intestine
Conditions such as malabsorption, leaky gut, and migraines point to problems in the small intestine. The main role of the small intestine is nutrient absorption. If this process is impaired, undigested nutrients may pass into the colon instead of being absorbed. In cases of a "leaky gut" (increased intestinal permeability), undigested particles can enter the bloodstream, triggering an immune response. This can lead to symptoms like food allergies, inflammation, or even migraines.

Diarrhea and Constipation
These symptoms are typically related to the colon (large intestine). The primary function of the large intestine is to absorb water and form solid stool for elimination.

Diarrhea can result when toxins or harmful bacteria in the colon trigger it to draw in more water in an attempt to flush them out. Overuse of laxatives can also cause diarrhea.

Constipation is often due to inadequate fiber and water intake. Since the colon absorbs water, a lack of hydration can lead to overly hard, dry stools. Dietary fiber, especially from fruits and vegetables, is a non-digestible carbohydrate that supports healthy bowel movements by improving motility. Without enough fiber and water, stool moves slowly and becomes compacted, leading to constipation.
