Functional gastrointestinal disorders are the most common diseases of the digestive system. These diseases are also known as gastrointestinal dysfunction, gastrointestinal motility disorders and gastrointestinal neuroses. These diseases are a general term for a group of gastrointestinal syndromes, which are caused by disorders of higher neural activity leading to malfunction of the vegetative nervous system, mainly motor and secretory dysfunction of the stomach and intestines, without histological organic pathological changes, excluding gastrointestinal tract dysfunction caused by other systemic diseases. Features of functional gastrointestinal disorders: The course of the disease is relatively long, usually lasting several months or even years. The onset of the disease is slow, with intermittent episodes, often with periods of remission, i.e., symptoms are sometimes mild and sometimes severe, sometimes good and sometimes bad. There is variability in the patient’s symptoms, i.e., the same disease can manifest itself differently in different individuals; there is often excessive mental tension, family disputes, difficulties in life and work, etc. It is often accompanied by palpitations, shortness of breath, chest tightness, redness, insomnia, anxiety, inattention, forgetfulness, hypersensitivity, sweaty hands and feet, polyuria, headache and other manifestations of plant nervous imbalance. Performance of functional gastrointestinal disease: Functional gastrointestinal disease is mainly based on gastrointestinal symptoms, and most patients have mental symptoms such as anxiety, insomnia, forgetfulness, hypersensitivity, easy fatigue and lack of concentration. The clinical manifestations of different functional gastrointestinal disorders vary, and patients often exhibit one or several gastrointestinal symptoms: patients with functional dyspepsia mainly have epigastric pain and discomfort, epigastric fullness, early satiety, nausea, etc. Patients with irritable bowel syndrome often have abdominal discomfort or abdominal pain with abnormal stool frequency and character as the main symptom. Functional constipation, on the other hand, is mainly characterized by reduced frequency of bowel movements, difficulty in defecation or a sense of incomplete defecation. There is another type of functional gastrointestinal disease that is more common, namely functional bowel disease with abdominal discomfort such as flatulence, increased or uncontrolled exhaustion, colic, or with constipation and diarrhea. It is important to emphasize that the diagnosis of these diseases relies on endoscopy and routine biochemical tests to exclude organic diseases. What are the causes of functional gastrointestinal disorders? Functional gastrointestinal disorders are often associated with gastrointestinal motility disorders, visceral hypersensitivity, altered intestinal flora, and psychosocial-physiological factors. Genetic factors, environmental factors are also important factors, such as high workload, increased economic burden, fierce competition at work, too fast pace of life, layoff and unemployment, death of relatives, stimulation of accidents, interpersonal tension and family disputes. Food factors such as sour fruits, spices, alcohol, chili peppers and strong coffee are also triggers of this disease. Treatment of functional gastrointestinal disease: The key to the treatment of functional gastrointestinal disease is life conditioning, supplemented by medication and correcting the triggering factors for the cause. First of all, it is necessary to correctly understand from the ideological point of view that this disease is a functional disorder, will not be malignant, does not affect life expectancy, eliminate tension and anxiety, establish confidence to overcome the disease. Don’t pay too much attention to the gastrointestinal discomfort symptoms and try to work normally. Correctly treat the frustration and pressure in life and work, reduce the interference of bad emotions, and cultivate an open and cheerful character. Second, rationalize life, ensure a normal routine, and combine work and rest. Participate in physical exercise and group activities to distract, avoid sedentary, standing, more aerobic exercise, 3 to 5 times a week, each exercise for about 30 minutes. Third, pay attention to the diet conditioning. Diet should be light, eat more fresh vegetables and fruits, eat more coarse grains, drink more water, drink more yogurt. Avoid rough, greasy and stimulating food, avoid cold drinks, eat less and more meals, avoid tobacco, alcohol and coffee, etc. Avoid smoking, alcohol and non-steroidal anti-inflammatory drugs, and avoid foods that can induce symptoms in personal life experiences. Fourth, for gastrointestinal motility disorders and gastrointestinal visceral hypersensitivity, drugs that regulate gastrointestinal motility and reduce gastrointestinal irritation factors can be used. Commonly used pro-gastrointestinal motility drugs include: mosapride, domperidone, and etopride. Gastrointestinal antispasmodics include: pivetonium bromide, otibuterol. Stimulant-reducing medications include commonly used stomach acid inhibitors, digestive enzyme preparations, and intestinal probiotics. Patients with functional gastrointestinal disorders with significant depression and anxiety disorders can be treated with complementary anti-anxiety and depression medications. In fact, medications, both prescription and over-the-counter, are recommended to be used under the guidance of a medical professional.
