There are different types of external hemorrhoids which can range from a mild condition to a more serious condition known as a thrombosed hemorrhoid which is a hemorrhoid that has developed a blood clot and often requires hemorrhoid surgery. Regardless of the type of condition you may have there are some common causes of external hemorrhoids.
Constipation
Constipation causes you to strain during bowel movements as the result of passing a hard stool. This can lead to an external hemorrhoid condition and can exacerbate the condition if constipation is allowed to persist. When you strain during a bowel movement it places excess pressure on external hemorrhoids and can cause them to rupture and bleed.
Low Fiber Diet
A diet that is low in fiber causes constipation and irregular bowel movements which place excessive pressure on the anal veins and causes them to become swollen. A low fiber diet can exacerbate a hemorrhoid condition or cause external hemorrhoids to develop.
Sitting for Prolonged Periods of Time
If you have a job or other activity where you sit for long periods of time this can be one of the causes of external hemorrhoids. Sitting for prolonged periods of time creates added pressure on the anal veins causing them to become swollen and develop into external hemorrhoids.
Pregnancy
Pregnancy can cause external hemorrhoids due to excessive pressure that is applied to the anal veins as a result of the enlargement of the uterus. Pregnancy can also cause an external hemorrhoid condition to become worse if you do not remain active during the period of fetal growth.
Improper Fluid Intake
Lack of fluid intake causes constipation and other health problems that can cause an external hemorrhoid condition to develop. Also, if you drink a lot of carbonated beverages this can also contribute to external hemorrhoids.
Lack of Exercise
Lack of exercise and leading a sedentary lifestyle can result in external hemorrhoids. Exercise helps to keep the pelvic muscles toned which contributes to stronger muscles in the anal area. If the muscles in the anal area remain strong they can support anal tissues and prevent external hemorrhoids from developing.
Obesity
Obesity is often the result of a sedentary lifestyle or a health condition that causes weight gain. Obesity can be a primary cause of external hemorrhoids and causes them to get worse due to the excess weight that is applied to the exterior of the anal area.
Diarrhea
Chronic diarrhea can cause external hemorrhoids to develop and can exacerbate an existing hemorrhoid condition. Diarrhea makes it difficult to keep the affected area clean which creates further irritation to the anal area.
