What’s the cause of a loud fart?

There are two main reasons for farting very loudly, physiological and pathological, such as eating too fast, gas-producing food, bacterial infections and so on.
1. Physiological:
(1) Eating too fast: patients talk while eating to let too much air enter into the stomach together with food, and then because the gastrointestinal tract can not expel the gas out of the body in time, so they feel like farting a lot and it is very loud.
(2) Gas-producing food: If the patient consumes food that is easy to produce gas, such as radish and onion. All these foods will produce a lot of gas when they are digested in the body, thus farting and very loud.
2. Pathological: patients with intestinal infections will have a large number of harmful bacteria in their bodies, and these bacteria will produce a lot of gas during their growth, which will lead to more intestinal exhaust and loud.
Loud farting may also be caused by other reasons, if there is obvious discomfort, you need to go to a professional hospital immediately, under the guidance of the doctor for examination and treatment.
