Why does food go straight through?

Food may pass through the digestive system quickly due to several factors, including its composition, individual metabolism, and digestive health. High-fiber foods can speed up transit time, while certain medical conditions like irritable bowel syndrome (IBS) or infections can also contribute to rapid digestion. Additionally, psychological factors such as stress can affect gut motility, leading to faster passage. If this occurs frequently or is accompanied by other symptoms, it's advisable to consult a healthcare professional.
