Thrombosed Hemorrhoids: Causes, Symptoms, and Treatment

Thrombosed hemorrhoids are painful protrusions where blood flow is restricted in the veins just outside the rectum or in the anus. This blockage causes the veins to swell and eventually burst, leading to blood pooling and clotting under the skin. Thrombosed hemorrhoids are often extremely sensitive and can either protrude or remain inside the anus.

Prevalence of Thrombosed Hemorrhoids

Studies estimate that about 4.4% of adults in the U.S. have symptomatic hemorrhoids. Among them, 5-10% develop thrombosis, making it a relatively common condition.

 

Causes of Thrombosed Hemorrhoids

There are several common causes of thrombosed hemorrhoids:

  • Prolonged Sitting: Sitting for long periods can increase pressure in the veins, leading to swelling.
  • Heavy Lifting: Lifting heavy weights at the gym can trigger the development of these hemorrhoids.
  • Childbirth: Pregnancy increases hemorrhoid risk by 2-3 fold, and 25-35% of pregnant women develop hemorrhoids.
  • Bowel Straining: Excessive straining during bowel movements can cause the veins to rupture.

Gender and Age Factors

Thrombosed external hemorrhoids tend to occur more frequently in men, with a male to female ratio of 2.8:1. They are most common in individuals between the ages of 45-65 years, although they can occur at any age.

Symptoms and Healing Process

In many cases, thrombosed hemorrhoids may heal without any medical treatment. The blood clots under the skin can be reabsorbed by the body over a few weeks. However, during this period, you may experience significant pain and discomfort.

Home Remedies for Pain Relief

To manage hemorrhoid pain and prevent the condition from worsening, you can try the following remedies:

  • Soothing Balms: Use over-the-counter creams to ease pain.
  • Warm Baths: Soaking in a warm bath can help reduce discomfort.
  • Increase Fiber Intake: If constipation was the root cause, eating more fiber can make bowel movements easier and relieve pressure on the hemorrhoid.
  • Pain-Relief Creams: Creams that numb the area can help manage the pain until healing occurs.

Recurrence and Economic Impact

Without surgical intervention, thrombosed hemorrhoids have a recurrence rate of 40-50% within 3 years. This condition also has a significant economic impact. Hemorrhoid treatments account for over $800 million in healthcare costs annually in the U.S., as of 2019 data.

Hemorrhoid Cost Chart

Cost Aspect Details
Annual Healthcare Costs Over $800 million in the U.S. (as of 2019)
Percentage of Population 4.4% of U.S. adults have symptomatic hemorrhoids
Recurrence Rate 40-50% within 3 years without surgery
Effectiveness of Early Treatment 94% of patients experienced immediate pain relief with early surgical excision (within 72 hours)

When to See a Doctor

While thrombosed hemorrhoids are not usually dangerous, the intense pain may require professional medical care. A doctor can remove the blood clot, providing almost immediate relief. There are two common treatment options:

1. Clot Extraction

A small incision can be made to extract the blood clot. This is a simple procedure that offers quick relief. In fact, 94% of patients reported immediate pain relief after clot excision if performed within 72 hours of symptom onset.

2. Hemorrhoidectomy

In more severe cases, a full hemorrhoidectomy may be necessary. This surgery removes not only the blood clots but also the damaged veins, reducing the chance of future occurrences. Many patients report less post-operative pain with this approach compared to clot extraction alone.
