Can a chronic lack of oil and water affect bowel movements

Prolonged lack of oil and water (high-fat food) does not usually affect bowel movements, and there is no information that bowel movements are related to the intake of high-fat food.
The normal prognosis for defecation is related to the usual type of diet, eating habits, and diseases suffered by the organism, and there is no information from clinical studies that defecation is related to the intake of high-fat foods.
1. Constipation may be triggered by a poor mix of dietary structure, which may result in insufficient mechanical or chemical stimulation of the gastrointestinal tract by food, thus causing a slowing down of intestinal peristalsis. Foods with coarse fiber can absorb water and stimulate gastrointestinal peristalsis, thus facilitating the discharge of stool. Usually patients drink more water, also helps the discharge of stool.
2. Some gastrointestinal diseases such as enteritis, gastritis, dyspepsia, etc., can also affect the normal defecation of the body.
There is no information to prove that normal bowel movement is related to the intake of oil and water.
