Rectal prolapse mainly occurs when the rectal mucosa prolapses out of the anus during defecation. If the symptoms are severe, the rectal mucosa can also protrude out of the anus during prolonged standing or exertion. As for whether beef can be eaten, because beef is generally spicy and many cooking methods are spicy, spicy foods can affect bowel movements, causing congestion and swelling of the anal mucosa. Therefore, it is best to avoid spicy beef. Furthermore, beef tends to cause "internal heat" in the body, which can lead to constipation. It is recommended that patients with rectal prolapse eat more vegetables and fruits to maintain smooth bowel movements. Thus, if one really wants to eat beef, it's best to either not make it spicy or to eat it in moderation.
