As society continues to advance, more urban dwellers are entering white-collar professions. Due to prolonged sitting in offices with little physical activity, bodies gradually become flabby. Experts warn that frequent prolonged sitting may significantly increase the risk of developing hemorrhoids.So why does prolonged sitting cause hemorrhoids?
Soft chairs may be comfortable, but avoid prolonged sitting
Why does frequent sitting on soft chairs lead to hemorrhoids? The problem lies in "sitting for extended periods without moving." This is because maintaining a seated position for long durations, especially on soft surfaces, slows abdominal blood flow. Venous blood in the lower limbs cannot return effectively, obstructing circulation.Under these conditions, the rectal venous plexus becomes prone to varicosity, leading to blood stasis and eventually forming a cluster of veins—the very essence of hemorrhoids. Simultaneously, prolonged immobility reduces anal muscle activity, diminishing elasticity and contractile strength. This allows the rectal mucosa to prolapse, further contributing to hemorrhoid formation or aggravation.
Experts note that today's office workers often endure long hours, high stress, and irregular eating patterns. When hemorrhoids develop, delayed treatment allows symptoms to progress from initial bleeding to dripping blood and eventually spurting blood. This not only worsens the hemorrhoids themselves but can also lead to complications like anemia.
Some patients with internal hemorrhoids delay treatment, allowing the hemorrhoids to enlarge and worsen. During bowel movements, they may prolapse outside the anus.Initially, they may retract spontaneously, but over time, manual repositioning becomes necessary. Coughing or walking can trigger prolapse. If edema develops, combined with spasm of the anal sphincter muscle due to irritation from the prolapsed hemorrhoids, the prolapsed internal hemorrhoids can become incarcerated outside the anus. This leads to infection and necrosis, causing severe pain and significantly increasing the patient's suffering and inconvenience.
Recommendation: Sit on Hard Surfaces to Prevent Hemorrhoids
Experts advise sitting on hard benches or chairs to prevent hemorrhoids. This is because sitting on a firm surface allows the two ischial tuberosities to support the buttocks, ensuring unimpeded blood circulation. Office workers should avoid prolonged sitting and stand up to move around every 45 minutes.During leisure time, increase physical activity. Dietary choices should include fresh vegetables, fruits, and whole grains, along with adequate water intake.
In daily life, numerous factors contribute to hemorrhoid development. Beyond prolonged sitting, diet plays a significant role. For instance, individuals who frequently consume spicy foods are more prone to hemorrhoids than those who avoid them. Similarly, people who drink insufficient water are more susceptible than those who stay well-hydrated. These aspects warrant careful attention.
