The human digestive system comprises the gastrointestinal tract and digestive glands. The gastrointestinal tract is essentially a long tube consisting of the mouth, pharynx, esophagus, stomach, and small and large intestine. Each organ plays an important role and all must function well for digestion to be regular. The body absorbs nutrients from food passing through the digestive system. These nutrients and the energy they supply are necessary for the normal function of the body. If a part of the system malfunctions, problems with slow and irregular digestion occur. In short, the human digestive system is an organ system that digests and absorbs the food we take in.
The function of the small and large intestine is mainly:
- absorption of nutrients;
- elimination of toxic substances and waste;
- synthesis of some vitamins, which is carried out by probiotics, or so-called good bacteria.
The last phase of digestion takes place in the large intestine. In the large intestine, mainly water is absorbed, while microbes break down food residue that the human body is unable to digest on its own. The role of the large intestine is to form, store and expel stool. Waste material can remain in the large intestine for 12 to 24 hours. Intestinal walls comprise strong muscles that expel bowel content in controlled contractions.
Poor care for the digestive system results in slow and irregular digestion, which can lead to a number of problems. Furthermore, intestines make up a large part of our immune system and are in fact the body’s largest immune organ. It is said with good reason that a healthy diet is fundamental for a strong body. Taking good care of the digestive system is essential in maintaining health.
Today, increasing numbers of people experience problems with slow digestion and constipation. While the digestive rhythm varies from person to person, difficult and infrequent bowel movements – fewer than one a day – accompanied by a feeling of incomplete evacuation and bloating, generally constitute what is called slow digestion. Although infrequent bowel movements are compounded by a lack of physical activity, inadequate fluid intake, digestive disorders and medical conditions, stress, some medications, and delaying defecation, the main cause seems to be the food we eat, or rather don’t eat.
Slow digestion can lead to a prolonged presence of harmful substances in the body, decreased effectiveness of the immune system, and various health risks. Constipation and slow or irregular digestion can significantly reduce the quality of life and lead to a decline in work productivity, as well as the occurrence of depression and anxiety. This common condition has a major effect on health and the quality of life.
Human digestion is a very complex process that is ill-adapted to modern life. We are exposed to harmful substances present in our diet, medications, and the environment, which can have an adverse effect on our health and digestion. In order to alleviate chronic problems and strengthen the body, we should maintain regular bowel movements and rid the body of accumulated harmful substances.
