What are Internal Hemorrhoids Risk Factors?

Hemorrhoids aren’t generally the result of one cause. Instead, it’s usually a combination of factors that lead to swollen, enlarged, and inflamed veins.

The following are the most common risk factors:

Chronic Constipation or Diarrhea

Constipation and diarrhea can strain the veins in the lower bowel and rectum. If these gastrointestinal issues happen often, they can eventually lead to hemorrhoids. 

Consuming more fiber and improving gut health can help address chronic constipation.

Psyllium, a fiber supplement, is particularly useful for alleviating both constipation and diarrhea.²

Sedentary Lifestyle

Being sedentary, a lifestyle that involves little to no physical activity can contribute to constipation, making hemorrhoid disease worse or making someone prone to first-time hemorrhoids. On the other hand, moderate physical activity — 20 to 60 minutes from three to five days a week — can help reduce the risk of internal hemorrhoids.³

Obesity

Research has found a link between a high body mass index (BMI) and internal hemorrhoids.³ The extra weight puts pressure on the abdomen and veins in the rectum, increasing the chances of veins becoming swollen and inflamed. 

Pregnancy

Pregnancy is a risk factor for hemorrhoids. The straining during bowel movements with an enlarged uterus and the relaxing effect of the hormone progesterone on rectal veins can both cause swelling. 

It’s estimated that 25 to 35% of pregnant women develop hemorrhoids, usually during the last trimester or in the first month after delivery.⁴

Eating a Low-Fiber Diet

People who don’t consume enough fiber can have issues with chronic constipation, which makes a person more prone to internal hemorrhoids. 

This lifestyle factor is one of the easiest to address. Simply adding a variety of foods that contain soluble and insoluble fiber, such as leafy green veggies, nuts, seeds, and whole grains, can reduce the risk of hemorrhoids. 

Age 

Internal hemorrhoids are more likely with age because the tissues that support the veins in the rectum become weaker. 

Heavy Lifting

Lifting heavy objects, whether during weight lifting or simply lifting items for work, can strain the abdominal area, increasing hemorrhoid risk. 

Genetic Predisposition

People with family members who are prone to internal hemorrhoids are more likely to get them as well. 

Other Factors That Increase the Risk of Developing Internal Hemorrhoids

Anything that puts pressure on the veins or supporting tissue can make someone more prone to hemorrhoids.

Sneezing or frequent coughing can put pressure on the abdominal area. So can anal intercourse. Also, conditions that cause inflammation in the gastrointestinal system, such as Crohn’s disease and inflammatory bowel syndrome (IBS), can increase risk. 

When to See a Doctor 

Internal hemorrhoids can last for years if they aren’t treated. They can also get worse over time, leading to more bleeding and discomfort. If you have symptoms of internal hemorrhoids for more than one week, consider setting up an appointment with a hemorrhoid specialist.
