Internal Hemorrhoids Grades and Symptoms: A Guide
Learn how internal hemorrhoids grades and symptoms relate to prolapse, bleeding, and treatment. Know when rectal bleeding needs medical evaluation.
Rectal bleeding or a feeling of tissue coming down during a bowel movement can be unsettling, especially when you are not sure what those symptoms mean. Internal hemorrhoids are swollen vascular tissue inside the anal canal. Their grade is based mainly on whether they prolapse, or move outside the anal canal, and whether they return on their own. Symptoms can offer clues, but they cannot confirm a grade or explain every cause of bleeding.
Internal hemorrhoids grades and symptoms are related, but not identical. Earlier grades may cause bright-red bleeding with little or no pain, while later grades are more likely to prolapse and cause discomfort. A clinician must examine you to determine the grade and rule out other causes of rectal bleeding.
Understanding the grading system can make a clinical evaluation feel less mysterious. The sections below start with what internal hemorrhoids are, then explain how prolapse distinguishes the four grades and how that information may guide treatment discussions.
What Are Internal Hemorrhoids?
Hemorrhoids are naturally occurring vascular tissues within the anal canal. They help provide structure in this area and are not, by themselves, an abnormal finding. Internal hemorrhoids develop inside the anal canal, above the area where the tissue is typically more sensitive to pain. They are traditionally grouped into Grades I through IV according to how much the tissue prolapses, or moves down and out of its usual position. This grading system helps clinicians describe what they see during an evaluation; symptoms alone cannot establish a grade.
Prolapse does not mean that every person will notice tissue outside the anus. A Grade I internal hemorrhoid may bulge into the anal canal without prolapsing. With more advanced prolapse, tissue may move out during a bowel movement, return on its own, require gentle manual reduction, or remain outside. Those distinctions are made during an appropriate clinical assessment, not by trying to grade the condition at home.
Because hemorrhoidal blood vessels have many arteriovenous connections, bleeding from hemorrhoids is often bright red. It may appear on the stool, toilet paper, or in the toilet bowl after a bowel movement. However, rectal bleeding should not automatically be attributed to hemorrhoids. Other digestive conditions can also cause bleeding, so new or recurring bleeding deserves appropriate medical attention.
Understanding the difference between internal tissue, prolapse, and other anorectal symptoms can make a sensitive conversation easier. You can review more anorectal and pelvic health conditions and discuss any concerns with a qualified clinician.
How Internal Hemorrhoids Grades and Symptoms Differ by Stage
Clinicians traditionally classify internal hemorrhoids from grade I through grade IV according to how far the tissue prolapses, or moves down from its usual position. The grade describes prolapse, not simply how much bleeding, pressure, or discomfort someone feels. A person cannot reliably determine a grade from symptoms alone.
| Grade | What happens | What a person may notice |
|---|---|---|
| Grade I | The hemorrhoid bulges into the anal canal but does not prolapse outside it. | There may be bleeding or no noticeable symptoms. Because it does not prolapse, there is no tissue to push back into place. |
| Grade II | The hemorrhoid prolapses during a bowel movement, then reduces, or returns inside, on its own. | A person may notice temporary tissue or pressure during straining, followed by spontaneous improvement. |
| Grade III | The hemorrhoid prolapses and does not return inside without manual reduction. | Tissue may remain outside after a bowel movement and require gentle manual assistance to move back inside. |
| Grade IV | The hemorrhoid is prolapsed and cannot be manually reduced. | Persistent prolapsed tissue may cause ongoing discomfort, irritation, or difficulty keeping the area clean. |
These distinctions come from the clinical grading system based on prolapse. Grade I tissue does not prolapse. Grade II tissue reduces on its own. Grade III tissue requires manual reduction. Grade IV tissue cannot be manually reduced. This progression does not mean every person experiences the same level of pain or bleeding at each grade.
For example, non-prolapsed internal hemorrhoids are often not painful, while prolapsed internal hemorrhoids may cause pain or discomfort. Internal hemorrhoids can also cause bright red blood on the stool, toilet paper, or in the toilet bowl after a bowel movement. However, bleeding should not automatically be attributed to hemorrhoids. Other digestive conditions can also cause rectal bleeding.
An examination is needed to determine whether hemorrhoids are present, whether internal tissue has prolapsed, and what grade best describes it. A clinician may consider your history and examine the area rather than relying on a symptom checklist. Evaluation is especially important when bleeding is new, persistent, or accompanied by other changes. The traditional grading approach is also summarized in this clinical reference on hemorrhoids. The goal is not to label symptoms on your own, but to identify the cause and discuss appropriate care.
What Symptoms Can Internal Hemorrhoids Cause?
Internal hemorrhoids do not cause the same symptoms for everyone. When they have not prolapsed, they are most often not painful. Some people notice no symptoms at all, while others see bright-red blood on the stool, toilet paper, or in the toilet bowl after a bowel movement. This bleeding pattern can occur with internal hemorrhoids, but it should not be assumed to identify the cause.
Prolapse can change how symptoms feel. A hemorrhoid that moves down during a bowel movement may create pressure, fullness, irritation, or the sensation that tissue is present at the anal opening. Prolapsed internal hemorrhoids may also cause pain and discomfort. The presence and intensity of these symptoms can vary, and not every person with a particular grade will experience every symptom.
Symptoms can overlap because bleeding, irritation, pressure, and discomfort may have several possible causes. Rectal bleeding can also be associated with other digestive tract problems, so appropriate evaluation for rectal bleeding matters, even when hemorrhoids seem likely. Anal fissures and other conditions may also produce other causes of anal discomfort.
Symptoms alone cannot establish the grade of an internal hemorrhoid or confirm that hemorrhoids are responsible. An examination helps a clinician assess what is happening and determine whether further evaluation is appropriate. If you notice new, recurring, or persistent bleeding, discomfort, or tissue protruding from the anus, arrange a clinical evaluation rather than trying to grade the condition yourself.
How Are Internal Hemorrhoids Diagnosed?
Diagnosis usually begins with a conversation about what you have noticed, when symptoms started, bowel movements, bleeding, discomfort, and any tissue that seems to protrude. A clinician then performs an appropriate physical examination. Medical history and examination, rather than routine laboratory testing or imaging, are the usual foundation for diagnosing hemorrhoids.
The purpose is not only to identify hemorrhoids. It is also to understand whether another condition could explain the symptoms. Rectal bleeding should not automatically be attributed to hemorrhoids. The evaluation for rectal bleeding may be important when the source is uncertain, the bleeding is new or persistent, or other symptoms are present.
Symptoms can suggest what is happening, but they cannot assign a grade by themselves. Internal hemorrhoids grades and symptoms do not always match in a predictable way. The grade is based on the degree of prolapse, which means whether tissue moves downward and whether it returns on its own or needs help. An individual assessment is needed, as explained by Pelvic Health Institute of Illinois.
You can expect the clinician to listen, explain what the evaluation is intended to clarify, and discuss next steps in plain language. You do not need to arrive with a self-diagnosis or a guessed grade. Sharing the color and amount of bleeding, whether tissue protrudes, and how symptoms affect daily activities can help make the visit more useful.
How Is Each Grade Treated?
Treatment is based on the examination, the degree of prolapse, symptoms, and how you respond to initial care. A grade does not automatically determine one procedure, and symptoms alone cannot establish the grade. The usual approach is conservative first, with office treatment or surgery considered only when clinically appropriate.
Grade I
Grade I hemorrhoids remain inside the anal canal. If they cause bleeding or irritation, care may begin with measures that reduce straining and support easier bowel movements. A clinician may recommend individualized changes involving bowel habits, fiber, fluids, or medication. If symptoms continue despite conservative care, an office procedure may be discussed.
Grade II
Grade II hemorrhoids may prolapse during a bowel movement and then return on their own. Conservative care may still be reasonable, particularly when symptoms are limited. When that approach does not provide enough relief, rubber band ligation is one office-based option for appropriate grade I to III internal hemorrhoids. This option is discussed in an evidence review from the American Academy of Family Physicians. Read more about how hemorrhoid banding works, including what the procedure involves and why a clinician must determine whether it fits your situation.
Grade III
Grade III hemorrhoids prolapse and require manual reduction. Treatment may still begin with measures that address bowel habits and straining. If symptoms persist, an office procedure such as banding may be considered. Other procedures can be appropriate for selected patients, but the choice depends on the examination, the amount of prolapse, and the overall clinical picture. The goal is not to treat a grade in isolation, but to select a suitable level of care.
Grade IV
Grade IV hemorrhoids remain prolapsed and cannot be manually reduced. They are more likely to require a procedural or surgical discussion, although the recommended plan depends on the individual findings. Excisional hemorrhoidectomy can offer greater surgical success than office procedures but may involve more pain and a longer recovery. For that reason, guidance commonly reserves hemorrhoidectomy for recurrent or higher-grade disease rather than using it as a first step for everyone.
Pelvic Health Institute of Illinois provides physician-led, non-surgical anorectal care, but not every option is appropriate for every patient. Review conservative hemorrhoid treatment options for background, then seek an evaluation before assuming that bleeding, prolapse, or discomfort reflects a particular grade.
When Should You Stop Waiting and Seek Care?
It is reasonable to try gentle at-home measures for mild symptoms, but waiting indefinitely can delay the right evaluation. The National Institute of Diabetes and Digestive and Kidney Diseases advises seeking medical help if you have bleeding from the rectum. Rectal bleeding may occur with hemorrhoids, but it can also reflect other digestive tract problems, including inflammatory bowel disease or colorectal cancer. Do not assume that blood is from hemorrhoids simply because you have noticed swelling, itching, or constipation.
Arrange an evaluation if you notice blood on the toilet paper, stool, or in the toilet bowl, especially if the bleeding returns or you are unsure where it is coming from. A clinician can consider the full pattern of symptoms and determine whether hemorrhoids or another anorectal condition may be involved. You can learn more about evaluation for rectal bleeding before your visit.
You should also contact a clinician when symptoms continue after one week of appropriate at-home care. Ongoing prolapse, irritation, discomfort, or difficulty managing bowel movements deserves attention even if the symptoms are not severe. Symptoms alone cannot establish whether an internal hemorrhoid is grade I, II, III, or IV, so trying to assign a grade at home may create false reassurance or unnecessary worry.
Seeking care does not mean you will need a procedure. At Pelvic Health Institute of Illinois, evaluation supports a plan based on the cause, severity, and persistence of your symptoms. For practical questions about what an appointment may involve, review these answers about anorectal care.
Can Internal Hemorrhoid Symptoms Be Prevented?
There is no guaranteed way to prevent internal hemorrhoids or every symptom they may cause. However, some everyday factors can increase pressure and irritation in the anal area. NIDDK identifies straining during bowel movements, sitting on the toilet for long periods, chronic constipation or diarrhea, and a low-fiber diet as contributors. Pregnancy and age-related weakening of supporting tissues can also play a role.
Practical steps may include giving yourself enough time to have a bowel movement without forcing it, avoiding prolonged toilet sitting, and paying attention to bowel regularity. If constipation or diarrhea is ongoing, it is reasonable to discuss the cause and appropriate treatment with a healthcare professional rather than repeatedly self-treating. A clinician or registered dietitian can also help you decide how to increase fiber and fluids safely for your individual needs.
- Avoid straining and prolonged toilet sitting.
- Discuss ongoing constipation or diarrhea with a healthcare professional.
- Ask for individualized guidance before changing fiber, fluids, or medication.
Some risk factors cannot be changed. Pregnancy and normal tissue changes with aging do not mean you caused the problem, and they do not make symptoms something you must simply accept. They may make individualized guidance especially useful.
These habits may reduce contributing strain, but they cannot confirm whether bleeding or discomfort comes from internal hemorrhoids. Rectal bleeding should be evaluated, since other digestive conditions can cause it. An examination is needed to determine the cause and, when relevant, the hemorrhoid grade.

Frequently Asked Questions
How do I know if my hemorrhoid is grade 3 or 4?
Grades are based mainly on prolapse, not on pain or bleeding alone. A grade III internal hemorrhoid protrudes and must be gently pushed back in. A grade IV hemorrhoid remains prolapsed and cannot be manually reduced. Symptoms cannot establish the grade reliably, so an examination is needed.
How do you know if you have severe internal hemorrhoids?
Persistent prolapse, difficulty reducing the tissue, significant discomfort, or recurring bleeding may warrant prompt evaluation, but these symptoms do not prove how severe the condition is. Internal hemorrhoids that have not prolapsed are often not painful, while prolapsed hemorrhoids may cause pain or discomfort. A clinician can assess the cause and grade.
Do grade 2 internal hemorrhoids go away?
Grade II hemorrhoids prolapse during a bowel movement and return inside on their own. Symptoms may improve with measures that reduce straining and support regular bowel habits. If symptoms continue, a clinician can discuss conservative care and, when appropriate, office-based treatment. The right plan depends on your examination and symptoms.
Do grade 4 hemorrhoids ever go away?
Grade IV hemorrhoids remain prolapsed and cannot be pushed back in. They may require more involved treatment than earlier grades, but the appropriate approach varies by the individual. Do not try to diagnose yourself from appearance alone. Arrange an evaluation to confirm the cause and discuss medically appropriate options.
When should I seek care for rectal bleeding?
Rectal bleeding should be discussed with a clinician rather than automatically attributed to hemorrhoids. The National Institute of Diabetes and Digestive and Kidney Diseases advises seeking medical help for bleeding from the rectum and for symptoms that continue after one week of at-home treatment: NIDDK guidance.
Schedule a Consultation
Rectal bleeding, prolapse, or hemorrhoid symptoms can be difficult to sort out on your own, especially when symptoms do not reveal the underlying cause or grade. A consultation can provide a thoughtful evaluation and help clarify which treatment options may fit your needs.
