"Can someone who has never had hemorrhoids develop them?"

The occurrence of hemorrhoids is not necessarily related to age, meaning that individuals who have never had hemorrhoids can still develop them. The reasons for hemorrhoid development are multifaceted, encompassing lifestyle habits, dietary habits, anorectal diseases, adverse pregnancy conditions, genetic factors, racial factors, among others.

Contributing Factors:

1. Lifestyle Habits: The anus and rectum are in a state of extreme retraction, which can easily lead to obstruction of local venous return. Additionally, the absence of venous valves around the anal canal increases the risk of hemorrhoid development.

2. Dietary Habits: Frequent alcohol consumption or ingestion of large amounts of irritating foods can cause venous congestion around the anal canal and rectum, impairing venous return and, over time, increasing the likelihood of hemorrhoid development.

3. Anorectal Diseases: Conditions such as prostate hyperplasia, hypertrophy, anal fissures, and anal fistulas can cause difficulty in defecation, leading to increased abdominal pressure and, consequently, hemorrhoid development.

4. Adverse Pregnancy Conditions: During pregnancy, the enlarging uterus compresses venous return, which can cause hemorrhoids.

5. Genetic Factors: Research indicates a familial predisposition to hemorrhoid development. Children of parents with hemorrhoids have a relatively higher risk of developing them.

6. Racial Factors: Hemorrhoids are more prevalent among Caucasians, particularly in Africa and the Americas, indicating notable racial differences.

Moreover, hemorrhoids can arise from the downward displacement of anal cushions and pathological dilation and tortuosity of veins around the anus and rectum. Malnutrition can weaken local tissues, making some individuals more susceptible to hemorrhoids. Chronic constipation, often due to occupational factors or poor dietary and lifestyle habits, is also a trigger for hemorrhoid development.

Even individuals who have never experienced hemorrhoids should reasonably adjust their dietary structure, sleep-wake patterns, and bowel habits, avoiding prolonged sitting or squatting, overexertion, staying up late, and mental stress.
