Know the basics

What is thrombosed internal hemorrhoids?

Hemorrhoids or piles are swollen veins in your anus and lower rectum, similar to varicose veins. Almost everyone has hemorrhoids, and it is no cause for concern if the piles do not swell. When hemorrhoids are swollen, you may experience itching and pain around the anus, making it difficult to move bowels.

Thrombosed internal hemorrhoids occur when a blood clot forms inside the hemorrhoid. Although this condition is not dangerous, it can cause excruciating pain.

  • Swelling or lumps around the anus
  • Fever, caused by an abscess, is considered a symptom

What causes thrombosed internal hemorrhoids?

You may develop hemorrhoids when excessive pressure is applied on the anal passage. This may be caused by:

  • Straining during bowel movements, especially when experiencing constipation

How is thrombosed internal hemorrhoids diagnosed?

You should see a doctor if you experience pain or itching around the anus or find blood in your stool, both of which are signs of colorectal cancer (CRC). 

The doctor will enquire about your symptoms and medical history. During the examination, they may insert a gloved and lubricated finger into your rectum to feel for lumps or growths.

If you show signs or are at risk of colon cancer, you may need to undergo some of the following tests to help the doctor visualise the depths of your colon:

  • Sigmoidoscopy: The doctor inserts a special colonoscopic device into your body through the anus to view the lower part of the colon. This test allows the doctor to look for precancerous growths (called polyps), and other changes in the colon.
  • Colonoscopy: The doctor uses an endoscopic device to study the entire length of the colon.

How is thrombosed internal hemorrhoid treated?

A common treatment for thrombosed hemorrhoids is thrombectomy. To perform this procedure, you would receive local anesthesia before the doctor performs an incision at the clot to drain it.

To yield the best results, it would be best to undergo this procedure a few days after the hemorrhoid appears.

If thrombectomy is ineffective, surgery may be required. Below are some available surgical options:

  • Hemorrhoidectomy: This procedure removes hemorrhoids, along with the clot and blood vessels. This method is more invasive than others and usually only performed in severe cases.
  • Rubber band ligation: The doctor would place a small elastic band at the base of the hemorrhoid to cut off blood flow, causing it to shrink in a few weeks.
  • Stapled hemorrhoidopexy: This procedure is known as the Longo procedure or procedure for prolapse and hemorrhoids (PPH). In this procedure, the doctor will use a stapling instrument to affix the hemorrhoids back in place.

Home remedies which could help relieve pain and discomfort caused by hemorrhoids include:

  • Hemorrhoid cream: Over-the-counter hemorrhoid creams can introduce instant relief to the symptoms.
  • Over-the-counter pain relievers: These can help alleviate the pain and discomfort. 
  • Sitting in warm baths: Soak the affected area in warm water several times a day and gently pat dry.
  • Ice treatment: Apply a cold compress or ice pack to the affected area to reduce pain and inflammation.
  • Witch hazel: Applying witch hazel may reduce itching and pain in the affected area.
  • Using wipes: Use wet wipes instead of toilet paper to reduce friction and irritation in the affected area.
  • Aloe vera: Aloe vera has anti-inflammatory properties that can reduce inflammation in the affected area.
  • Stool softeners: You can use stool softeners or consume lots of fibre to treat hemorrhoids at home. This will make it easier to move bowels.
  • Wearing loose cotton clothing: This can reduce irritation in the affected area and keep it dry.

Know the prevention

What measures help prevent thrombosed internal hemorrhoids?

You may not always be able to prevent hemorrhoids, but certain measures can help reduce the risk of getting the disease, and they include:

  • Consuming high-fibre foods such as broccoli and other vegetables to help maintain regular bowel movements.
  • Being more active and avoid sitting for long hours.
