Physiological period farts may be hormone level changes, stomach cold, ate more gas-producing food 1. Changes in hormone levels: prostaglandin levels may rise during physiology, and prostaglandins can stimulate the smooth muscle of the gastrointestinal tract, causing gastrointestinal peristalsis to accelerate. The gas in the intestines may be discharged from the body more quickly than usual. So the farts during physiological period may be caused by the change of hormone level. This is mostly normal and usually requires no special treatment. 2. Cold stomach: The body’s resistance is weak during physiological period and it is easy to be attacked by cold. Cold air stimulates the gastrointestinal tract to cause gastrointestinal peristalsis to enhance, thus appearing physiological period farts and other symptoms. It can be dealt with by physical methods, such as using hot water bags, warm babies, and wearing more clothes. 3. Eating more gas-producing foods: Certain foods, such as potatoes and sweet potatoes, may produce more gas when they enter the body. If you eat more of these foods during your physiological period, you may experience more farts during your physiological period. This can be regulated by diet, such as eating less gas-producing foods. When there is a situation of excessive farts during physiological period, if necessary, timely consult a doctor, perfect abdominal ultrasound, endoscopy under the guidance of the doctor, etc., to clarify the cause of the disease, and active treatment.
