An Unconventional Way to Improve Memory
Decreased memory, difficulty focusing on important events, and retaining information in the mind are troubling signs that lead one to think primarily about disorders of the nervous system. However, aside from the nervous system, the human body also possesses a "second brain" - the gastrointestinal tract (GIT)1. If memory problems arise, it’s advisable to pay attention to its condition.
The Connection between Memory and the Gastrointestinal Tract
Many people mistakenly believe that the task of the GIT is merely to supply the body with energy through the processing and absorption of nutrients. However, the stomach and intestines are far more complex organs, and within the intestines resides a vast number of microorganisms that also influence the nervous system, including one’s ability to memorize information.
Important!
РSeveral experiments conducted in Canada have demonstrated that changes in the composition of gut microbiota can affect the normal functioning of the nervous system 2.
The thing is, memory is a complex process that is facilitated not only by the interaction of neurons but also by the production of various hormones and neurotransmitters. A good example is serotonin, which participates in the process of memorizing new information and is produced in the intestines. Naturally, if a person has GIT disorders, their ability to memorize information and focus on tasks is also diminished.
For instance, a study conducted in June 2023 demonstrated that patients suffering from irritable bowel syndrome experience a reduction in verbal IQ, meaning their ability to recall words at the right moment and use them appropriately3.
Today, the existence of the gut-brain axis is well established, and its functioning is still being studied.

GIT Diseases that Can Affect Memory
Given the proven existence of the gut-brain axis, it’s not surprising that disruptions in intestinal or other GIT organ functioning can lead to nervous system problems, especially cognitive abilities. This includes the process of memorization. Certain GIT disorders particularly influence the ability to memorize. Among them are:
- Gastric and intestinal ulcers
- Irritable bowel syndrome (IBS)
- Gastritis
- Cholecystitis
- Liver insufficiency
Diseases that compromise the integrity of the gastrointestinal mucosa not only deteriorate memory but also increase the likelihood of developing depression 4.
When memory problems arise, making it increasingly difficult to remember new information and concentrate, it’s a signal to assess the state of the gastrointestinal tract. If the disorder is in its early stages, there’s a good chance of addressing the issue through dietary corrections, the addition of vitamin or mineral supplements to the standard diet. The key is not to overlook the initial symptoms.
