The causes of gastrointestinal discomfort in the fall, such as cold air stimulation of the gastrointestinal tract, poor eating habits, too little exercise and other causes. 1. Cold air stimulation of the gastrointestinal tract: Because of the large temperature difference between day and night in autumn, once the gastrointestinal tract is stimulated by cold air, spasmodic contraction may occur, which leads to gastrointestinal discomfort. 2. Poor diet: Because the weather gradually turns cooler in autumn, the patient’s appetite may become more and more vigorous, and after eating too much food at each meal, the burden on the gastrointestinal tract may be aggravated, which may lead to gastrointestinal discomfort symptoms in patients. 3. Exercise too little: Because patients may not exercise often in the fall because of the cold weather, their gastrointestinal peristalsis may be relatively slow, especially if they sit down to work immediately after a meal, which makes them more prone to gastrointestinal symptoms. When gastrointestinal discomfort occurs in the fall, attention should be paid to adjusting the diet, paying attention to abdominal warmth, and exercising appropriately. If the symptoms of gastrointestinal discomfort are not relieved by the above measures, you should go to the gastroenterology department of the hospital in a timely manner, and the doctor will clarify the cause of the disease through the relevant examination, and according to the specific circumstances, targeted treatment.
