Intestinal problems may have different origins, such as:
Improper diet
Certain foods are difficult to digest, resulting in increased contractions of the muscles of the intestine, or bloating.
Stress
Stress in itself is not a cause of digestive discomfort, but numerous observations have shown that the intensity of the impulses are influenced by anxiety.
An infection
it is possible that digestive discomfort is caused by a bacterium, virus or parasite.
Family history
A hereditary factor could intervene in triggering digestive discomfort, but this hypothesis has not yet been confirmed.
An imbalance of the intestinal flora
after taking antibiotics for example.
