Low back pain and farts are mostly caused by different diseases. Low back pain can be caused by lumbar disc herniation, lumbar muscle strain, acute lumbar sprain, etc., while farts are mostly caused by gastrointestinal dysfunction. The symptoms of lumbar pain will gradually aggravate with the degeneration and hyperplasia of lumbar intervertebral disc structure. Excessive bending activities or incorrect exercise posture will make most of the focus point in the lumbar, resulting in lumbar muscle strain, resulting in aseptic inflammation and cause back pain. Sudden bending down when carrying heavy objects can lead to acute lumbar sprains, resulting in soft tissue injuries in the lower back and causing low back pain symptoms. Most of the farting symptoms are caused by gastrointestinal tract dysfunction due to gastrointestinal tract inflammation or intestinal flora imbalance, etc., so that the food piled up in the stomach can not be digested and absorbed adequately, which leads to the production of a large amount of gas in the digestive tract and causes farting symptoms. Therefore, back pain and farting are caused by two different reasons and cannot be caused by the same disease. When both back pain and farting are present at the same time, it is important to go to the hospital in time in order to clarify the cause of the disease.
