Old farting is usually not related to myocardial ischemia, and can be considered to be caused by liver problems, intestinal problems, dietary factors and other aspects. 1. Liver problems: If you suffer from acute and chronic hepatitis, you may experience nausea and vomiting, indigestion, and even an increase in farting. 2. Intestinal problems: when intestinal dysfunction occurs, due to intestinal flora imbalance, there may be a decrease in probiotics and an increase in harmful bacteria, which can break down intestinal food to produce ammonia and lead to farting. 3. Dietary factors: If you consume food containing too much carbohydrate, such as soy products, it will increase gas production in the intestinal tract, resulting in the phenomenon of old farts. It is recommended that people who suffer from farting should consult a doctor in time to identify the cause, and if treatment is needed, it should be standardized under the guidance of a doctor.
