Gastrointestinal food intolerance

　　Food that can cause systemic reactions includes such as bigeye tuna, rice, shrimp, wheat and corn foods, etc. The pathogenesis of food intolerance is not yet clear, and it may involve multiple aspects such as immune response, enzyme deficiency, pharmacological action, but does not include pathogenic microorganisms, chemical toxins, toxic reactions of irritant foods, and subjective aversion to food. Commonly intolerant foods include milk, eggs, wheat, corn, nuts, soybeans, and shellfish, etc. Currently, more than 90 types of food can be tested.

　　What diseases can gastrointestinal food intolerance trigger? The following is a brief description:

　　1. Food intolerance and irritable bowel syndrome (IBS). IBS is the earliest discovered disease that may be related to food intolerance. It is a motility disorder that affects the entire digestive tract, causing recurrent symptoms of the upper and lower gastrointestinal tract, including varying degrees of abdominal pain, constipation or diarrhea, abdominal distension, etc., and the etiology is still unknown.

　　2. Food intolerance and dermatitis. The symptoms of food allergy and food intolerance are most commonly manifested on the skin. Immediate-type reactions include measles, angioneurotic edema, and erythema. Delayed-type reactions may include severe rash (many are genetic contact dermatitis).

　　3. Food intolerance and migraine. For a long time, many clinical doctors have found that there is a certain relationship between food intolerance and migraine. Food intolerance can cause norepinephrine secretion, leading to vasoconstriction or vasodilation and stimulating the trigeminal nerve, brainstem, and cortical pathways.

　　4. It can also trigger complications such as urticaria, angioedema, purpura, bronchial asthma, allergic rhinitis, syncope, and hypotension.

　　What are the symptoms of food intolerance of the gastrointestinal tract? The following is a brief description:

　　In addition to gastrointestinal symptoms such as abdominal绞痛, nausea, and vomiting, there may also be edema of the lips, urticaria, angioedema, purpura, bronchial asthma, allergic rhinitis, syncope, and hypotension.

　　The prevention of gastrointestinal food intolerance lies in avoiding allergic foods, but it is often difficult to find allergic foods. Under strict observation and with emergency measures prepared, provocation tests should be conducted.

     Gastrointestinal food intolerance can be diagnosed based on the typical clinical manifestations of the patient, combined with the patient's medical history, and the main laboratory examination should be the allergen test, to find out the allergenic food. After determining the allergen, it should be avoided as much as possible.

　　What should be paid attention to in the dietary care of patients with gastrointestinal food intolerance?

　　1. Leftover food from the elderly is easy to cause the onset of gastrointestinal diseases.

　　2. Diet should follow the seasons. According to the characteristics of the dry climate and large temperature difference between day and night in early autumn, diet should follow the principle of 'less spicy and more sour', that is, to eat less spicy and stimulating foods and more sour fruits and vegetables, such as apples, pomegranates, grapes, mangoes, pomelos, lemons, hawthorns, etc. It is also appropriate to eat more vinegar, which can promote saliva, stimulate the appetite, and inhibit and kill bacteria, preventing intestinal infectious diseases. In addition, more should be eaten of Yin-nourishing and Drought-relieving products such as pears, tremella, sugarcane, honey, lotus root, black-bone chicken, soy milk, etc.

　　3. Pay special attention to eating fruits. Due to the drop in temperature, the Yang of the spleen and stomach is insufficient. Eating too many fruits with Yin and cold properties can lead to a lack of Yang and abdominal pain and diarrhea.

　　1. Treatment involves avoiding allergic foods, but it is often difficult to find allergic foods. It is necessary to conduct provocation tests under strict observation and with emergency measures prepared in case of an attack. Treatment with sympathomimetic drugs, antihistamines, and adrenal cortical hormones is effective during an attack.

　　2. Whooping cough may require tracheal intubation or tracheotomy. Non-specific treatment includes various symptomatic treatments for clinical symptoms. Specific prevention and treatment mainly involve dietary intervention. Generally, based on test results, negative foods can be eaten normally; mild sensitive foods should be alternated, that is, they should be eaten or avoided after an interval; for moderate and highly sensitive foods, they should be avoided directly. If there are many foods that are not tolerated and it is difficult to avoid all of them, the method of alternate intake should be adopted.
