Disease description:

After eating, I feel completely exhausted—especially in my arms and legs—so I just want to lie down. Sometimes, after meals, I feel weak all over, particularly in my arms and legs. What should I do?

This is likely a normal physiological response. After food enters the gastrointestinal tract, digestive organs consume a significant portion of the body’s blood and oxygen during digestion, leading to reduced blood flow and oxygen supply to internal organs—manifesting as fatigue. However, if generalized weakness persists for an extended period, it warrants attention, and timely upper gastrointestinal endoscopy at a hospital is recommended.
