What Are Internal Hemorrhoids?

Hemorrhoids are a very common condition that affect many adults in the United States, Europe, and around the world. They are swollen veins in the anal canal that can become twisted and enlarged due to pressure from straining during defecation. Internal hemorrhoids can cause a variety of unpleasant symptoms, including rectal pain, bleeding, itching and burning.

Types of Internal Hemorrhoids

Internal hemorrhoids can be classified according to their location and the severity of symptoms.

  • Grade 1: These hemorrhoids remain inside the anal canal and usually have no symptoms.
  • Grade 2: These hemorrhoids protrude from the anal opening when straining but go back inside on their own afterwards.
  • Grade 3: These hemorrhoids protrude from the anal opening and require manual manipulation to be pushed back inside.
  • Grade 4: These are the most severe type of internal hemorrhoids and require medical treatment.

Causes of Internal Hemorrhoids

The main causes of internal hemorrhoids are straining during bowel movements, constipation, pregnancy, and obesity. Other contributing factors include a low-fiber diet and a sedentary lifestyle.

The type and severity of symptoms determines the treatment for internal hemorrhoids. For Grade 1 hemorrhoids, lifestyle changes such as a high-fiber diet and exercise can help to alleviate symptoms. Grade 2, 3 and 4 hemorrhoids usually require more aggressive treatments, such as rubber band ligation, sclerotherapy, and surgical removal.
