Hemorrhoids, also known as piles, are swollen veins in the lower rectum or anus. While some are external and visible, internal hemorrhoids develop inside the rectum and often go unnoticed until they cause symptoms. Understanding internal hemorrhoids is key to early treatment, preventing progression, and improving comfort.
What Are Internal Hemorrhoids?
Internal hemorrhoids occur inside the rectum, above the dentate line, which is an area with fewer pain-sensitive nerves. This is why early-stage internal hemorrhoids are often painless. They develop when the veins in the rectum become swollen due to increased pressure, leading to bulging or protrusion during bowel movements.
Even though you may not feel them initially, internal hemorrhoids can progress if left untreated, eventually causing discomfort, bleeding, or prolapse.
Symptoms of Internal Hemorrhoids
Internal hemorrhoids often develop gradually and may not cause noticeable discomfort in the early stages. Because they form inside the rectum, an area with fewer pain-sensitive nerves, many people do not realize they have hemorrhoids until symptoms begin to appear. As the condition progresses, however, several signs can develop that indicate irritation or swelling of the rectal veins.
Some of the most common symptoms associated with internal hemorrhoids include:
- Bright red rectal bleeding: One of the earliest and most common signs is seeing bright red blood on toilet paper, in the toilet bowl, or coating the stool after a bowel movement. This bleeding is usually painless but should never be ignored.
- Prolapse: As internal hemorrhoids enlarge, they may push outside the anus during bowel movements. In early stages, they typically retract on their own once the bowel movement is complete.
- Mucus discharge: Some internal hemorrhoids produce mucus, which can irritate the surrounding skin and lead to itching or discomfort around the anal area.
- Sensation of fullness: Many people report feeling as though their rectum is not completely empty after a bowel movement, which can be frustrating and uncomfortable.
- Itching or irritation: If hemorrhoids prolapse or mucus leaks onto the skin, irritation and persistent itching can occur.
Although bleeding from internal hemorrhoids is often painless, any rectal bleeding should be evaluated by a healthcare professional. In some cases, similar symptoms may be caused by other conditions such as polyps, inflammatory bowel disease, or colorectal cancer, making proper diagnosis important.
Stages of Internal Hemorrhoids
Internal hemorrhoids are classified into four grades, which indicate their severity and treatment requirements:
Grade 1
- Hemorrhoids remain inside the rectum and do not prolapse.
- May cause painless bleeding during bowel movements.
- Usually managed with dietary changes, hydration, and over-the-counter remedies.
Grade 2
- Prolapse outside the anus during bowel movements but retract spontaneously.
- Symptoms include mild discomfort, itching, or bleeding.
- Conservative treatments and minimally invasive procedures like rubber band ligation may be recommended.
Grade 3
- Prolapse outside the anus requires manual repositioning.
- Bleeding, swelling, and discomfort are more pronounced.
- Treatments include Hemorrhoid Artery Embolization (HAE), rubber band ligation, or infrared coagulation.
Grade 4
- Permanently prolapsed and cannot be pushed back.
- Often painful, swollen, and prone to bleeding or thrombosis.
- Surgical intervention such as hemorrhoidectomy is usually required.
- Post-treatment care focuses on preventing recurrence and managing discomfort.

Causes and Risk Factors
Internal hemorrhoids typically develop when excess pressure builds up in the veins located inside the rectum. Over time, this pressure causes the veins to swell and stretch, leading to the formation of hemorrhoids. Many everyday habits and health conditions can contribute to this increased pressure, which is why hemorrhoids are a very common condition among adults.
Several factors can increase the risk of developing internal hemorrhoids, including:
- Chronic constipation or diarrhea: Frequent digestive issues can irritate the rectal veins and increase pressure during bowel movements.
- Frequent straining during bowel movements: Straining forces blood into the rectal veins, causing them to enlarge and become inflamed.
- Sitting for long periods, especially on the toilet: Spending extended time on the toilet places additional pressure on the rectal area and can worsen hemorrhoids.
- Heavy lifting or intense physical exertion: Repeatedly lifting heavy objects can strain abdominal and rectal muscles, increasing pressure in the veins.
- Pregnancy and childbirth: The growing uterus places pressure on pelvic veins, and pushing during labor can further contribute to hemorrhoid development.
- Aging and weakening of supportive tissues: As people age, the tissues that support the veins in the rectum can weaken, making hemorrhoids more likely to form.
Identifying and addressing these contributing factors early can help reduce symptoms, prevent flare-ups, and stop internal hemorrhoids from progressing to more advanced stages. Making simple lifestyle changes, such as improving diet, staying hydrated, and avoiding prolonged straining, can make a significant difference in managing the condition.
Treatment Options for Internal Hemorrhoids
Treatment depends on the grade of hemorrhoid and severity of symptoms:
Lifestyle and Home Care
- High-fiber diet and hydration to soften stool
- Avoid straining during bowel movements
- Sitz baths to reduce swelling and discomfort
- Gentle cleansing to prevent irritation
Minimally Invasive Procedures
- Hemorrhoid Artery Embolization (HAE): Blocks blood flow to shrink hemorrhoids naturally
- Rubber Band Ligation (RBL): Cuts off blood supply, causing hemorrhoid to fall off
- Sclerotherapy: Injection causes hemorrhoid to shrink
- Infrared Coagulation (IRC): Uses light to create scar tissue and reduce blood flow
Surgical Options
- Hemorrhoidectomy: Recommended for grade 4 or complicated hemorrhoids
- Stapled hemorrhoidopexy: Used for prolapsed internal hemorrhoids

What are internal hemorrhoids?
Internal hemorrhoids are swollen veins that develop inside the rectum. They are often painless in the early stages because they occur in an area with fewer pain-sensitive nerves. However, they can still cause symptoms such as rectal bleeding, mild discomfort, and prolapse during bowel movements.
Are internal hemorrhoids the same as piles?
Yes, piles is another commonly used term for hemorrhoids. Internal piles refer specifically to hemorrhoids that develop inside the rectum. They may not be visible at first but can cause bleeding, irritation, or protrusion as they progress.
What are the common symptoms of internal hemorrhoids?
Internal hemorrhoids often cause symptoms such as:
- Bright red blood during bowel movements
- A feeling of incomplete bowel emptying
- Mild itching or irritation
- Prolapsed tissue that may protrude from the anus
Many people first notice internal hemorrhoids when they see blood on toilet paper or in the toilet bowl.
Can internal hemorrhoids go away on their own?
Yes, mild cases of internal hemorrhoids or piles can sometimes improve with lifestyle changes. Increasing fiber intake, drinking more water, avoiding straining during bowel movements, and maintaining good hygiene can help reduce symptoms and allow hemorrhoids to shrink naturally.
What causes internal hemorrhoids or piles?
Internal hemorrhoids develop when there is increased pressure in the rectal veins. Common causes include:
- Chronic constipation
- Straining during bowel movements
- Prolonged sitting
- Pregnancy
- Low-fiber diet
Over time, these factors can weaken the veins and lead to swelling.
Can internal hemorrhoids become painful?
Internal hemorrhoids are usually painless at first. However, they can become uncomfortable if they prolapse outside the anus, become irritated, or develop complications such as thrombosis or inflammation.
What is the best treatment for internal hemorrhoids?
Treatment depends on the stage of hemorrhoids. Mild cases may respond to dietary changes, hydration, and over-the-counter remedies, while more advanced piles may require minimally invasive treatments such as rubber band ligation, sclerotherapy, or Hemorrhoid Artery Embolization (HAE).
