The Risk Factors and Causes of Hemorrhoids

Symptomatic hemorrhoids, also called piles, are enlarged blood vessels within the rectum or anus. Understanding the causes of hemorrhoids can help in preventing their development or managing their symptoms.

Hemorrhoid Causes and Risk Factors

While anyone can develop hemorrhoids, certain factors can make some people more prone to experiencing this condition.

Understanding why certain people are predisposed to hemorrhoids requires examining various contributing factors.


Pregnancy can make hemorrhoids more likely to occur. As the uterus grows, it puts added strain on the veins in the pelvic area, leading to the development of hemorrhoids.

Hormonal shifts during pregnancy can also weaken blood vessel walls, making them more vulnerable to swelling and inflammation.

Inherited Factors

Research has shown there is a familial aggregation of hemorrhoids, indicating a possible genetic predisposition. Several studies have found that people with a family history of hemorrhoids are more likely to develop the condition themselves. This correlation suggests that there may be specific genes or genetic variations that increase the risk of developing hemorrhoids.

Inherited conditions might include the following


Obesity is characterized by excessive body weight and an increased body mass index (BMI). While obesity itself is not a direct cause of hemorrhoids, it is believed to contribute to their development through several factors

Digestive Disorders

While constipation may not directly cause hemorrhoids, it can contribute to their development and aggravate existing hemorrhoids. Straining during bowel movements due to constipation puts increased pressure on the rectal area, causing the blood vessels to swell and potentially leading to hemorrhoids.

Additionally, hard and dry stools resulting from constipation can be difficult to pass, further straining the rectal area.


Age can be a contributing factor to the development of hemorrhoids. As we age, the tissues in the rectal area become less elastic and more prone to swelling and inflammation. The gradual weakening of tissues can increase the risk of hemorrhoids.


While the direct link between stress and hemorrhoids is not yet fully understood, several studies have explored this association. Research suggests stress may contribute to the development of hemorrhoids through multiple mechanisms.

Stress can lead to changes in bowel habits, including irregular bowel movements, constipation, or diarrhea. These changes can increase the pressure exerted on blood vessels in the rectal area, potentially predisposing patients to hemorrhoids.

Additionally, chronic stress can weaken the immune system, impairing its resistance to infection and inflammation. This weakened immune response may make people more susceptible to developing hemorrhoids or experiencing more severe symptoms.
