Old loud farts may be caused by physiological and pathological factors, such as excessive intake of gas-producing food, gastrointestinal dysfunction, enteritis, and so on. 1. Physiological factors: If the patient eats too much gas-producing food, such as sweet potatoes and potatoes, because the above food contains a large amount of starch, which will be fermented into hydrogen sulfide and ammonia under the action of intestinal flora, resulting in the patient’s constant loud farts, which is a normal phenomenon. 2. Pathologic factors: (1) Gastrointestinal dysfunction: intestinal dysfunction may be caused by biological factors, mental and psychological factors, which will lead to indigestion, abdominal distension, and may also lead to the symptom of constant loud farts. It is recommended to use intestinal probiotics, such as compound Lactobacillus acidophilus, under the guidance of a doctor for treatment. Use psychotropic drugs to assist when necessary. (2) Enteritis: Inflammatory reaction occurs when bacteria invade the intestinal tract. Pathogenic bacteria decompose food and produce more gas, which stimulates the gastrointestinal tract and accelerates the expulsion of gas, leading to the symptom of loud farts. Oral antibiotics, such as ofloxacin, are needed. There may be other reasons for loud farts, so you need to consult a doctor to find out the cause of the problem and treat the symptoms.
