Untreated hemorrhoids rarely become life-threatening, but they can progress in ways that make daily life significantly worse. What starts as occasional itching or minor bleeding during bowel movements can escalate into painful thrombosed lumps, chronic blood loss severe enough to cause anemia, and a psychological burden that measurably raises rates of anxiety and depression. Perhaps the most underappreciated risk is not from the hemorrhoids themselves but from the assumption that rectal symptoms are “just hemorrhoids” when they may signal something more serious.
Thrombosis and Acute Pain Episodes
The most dramatic thing that can happen to an untreated external hemorrhoid is thrombosis, where a blood clot forms inside the swollen vein. You wake up one morning with a hard, bluish lump near the anus and pain that can be intense enough to make sitting, walking, or having a bowel movement feel unbearable. Bleeding from a thrombosed hemorrhoid is uncommon unless the clot erodes through the overlying skin, but the pain alone can be debilitating and often drives people to seek emergency care.1PubMed Central. Management and Treatment of External Hemorrhoidal Thrombosis
If you ride it out without treatment, the clot and swelling typically resolve on their own over days to weeks. But “resolving” does not mean returning to normal. The stretched skin often leaves behind a residual skin tag, which can be hard to keep clean and may cause ongoing irritation. More critically, once you have had one thrombosis episode, the tissue in that area is weaker, and recurrences become more likely. People who have had one painful flare tend to have more, and each episode can be as severe as the first.
Chronic Bleeding and the Risk of Anemia
Internal hemorrhoids are the ones that bleed most. In the early stages, you might notice a streak of bright red blood on toilet paper or in the bowl. Many people dismiss this as trivial, and for a while it may be. But hemorrhoids that go unaddressed tend to enlarge over time. As the cushions prolapse further, episodes of bleeding can become more frequent and heavier.
In rare but documented cases, chronic hemorrhoidal bleeding causes iron-deficiency anemia. A study of patients in Olmsted County over a 15-year period found that hemorrhoidal bleeding severe enough to cause anemia occurred at a rate of about 0.5 per 100,000 people per year. The patients who did develop anemia had an average hemoglobin concentration of around 9.4 g/dL before treatment, well below normal, and the vast majority had grade 2 or 3 internal hemorrhoids that had gone unmanaged for extended periods.2PubMed. Evaluation of anemia caused by hemorrhoidal bleeding That rate sounds low, but the people it does affect often arrive at a doctor’s office feeling exhausted, short of breath, and lightheaded before anyone connects the dots to their ongoing rectal bleeding.
The particular danger here is the slow-drip nature of the blood loss. Losing a small amount daily does not trigger alarm the way a sudden hemorrhage would. Your body compensates for weeks or months, and by the time symptoms of anemia become noticeable, the deficiency can be significant. People on blood thinners or those with clotting disorders face an even higher risk, since their bleeding is harder to control naturally.
How Untreated Hemorrhoids Affect Quality of Life
The physical toll of hemorrhoids is straightforward to describe. The less visible toll on daily functioning and emotional well-being is often worse. Research comparing people with significant hemorrhoid symptoms to the general population has found that those with a high symptom burden score lower on standardized measures of physical health and overall health-related quality of life. The anatomical severity of the hemorrhoids, as judged by a surgeon during examination, did not predict quality of life nearly as well as the person’s own report of how much their symptoms bothered them. In other words, how the hemorrhoids feel to you matters more than how they look to your doctor.3PubMed Central. Quality of life in patients with hemorrhoidal disease
The symptoms that erode quality of life are persistent rather than catastrophic. Itching, soiling, discomfort while sitting, the need to plan activities around bathroom access, and the anxiety that comes with unpredictable bleeding all compound over time. People with desk jobs, long commutes, or physically demanding work report that untreated hemorrhoids interfere with their ability to do their jobs comfortably. Social activities and exercise can also take a hit, especially during flare-ups.
The Psychological Burden
Hemorrhoid disease carries a measurable psychological cost that goes beyond general discomfort. A study comparing people with hemorrhoidal disease to healthy controls found that patients had roughly double the depression and anxiety scores of people without the condition. Quality of life in the general health, physical, and social domains was significantly lower as well. The analysis confirmed that hemorrhoidal disease had direct effects on depression and anxiety, not just as a side effect of pain, but as a standalone contributor to worsened mental health.4World Journal of Psychiatry. Psychological burden of hemorrhoidal disease: Association with depression, anxiety, and quality of life impairment
Part of this is the embarrassment factor. Hemorrhoids are one of those conditions people avoid discussing even with close friends. The reluctance to talk about it extends to the medical system. A cross-sectional study of people who had hemorrhoidal symptoms but had not seen a doctor found that the most common reason for avoiding care, cited by about 40% of respondents, was the belief that symptoms would resolve on their own. But about 15% specifically said they stayed away because of shame, and nearly 10% cited fear of receiving a serious diagnosis. Another 6.5% were afraid of surgery.5PubMed Central. Barriers to Seeking Medical Care for Hemorrhoidal Symptoms: A Cross-Sectional Observational Study These barriers create a cycle: the longer you avoid treatment, the more likely the hemorrhoids are to worsen, and the more anxious you become about eventually having to deal with them.
The Danger of Assuming “It’s Just Hemorrhoids”
This is arguably the most important consequence of leaving hemorrhoids unexamined rather than untreated, because the two are not the same thing. Self-diagnosing rectal symptoms as hemorrhoids without a medical evaluation can delay the detection of conditions that share overlapping symptoms, including colorectal cancer, inflammatory bowel disease, and anal fissures.
A qualitative study of Thai colorectal cancer patients found that many had initially attributed their symptoms, including rectal bleeding and changes in bowel habits, to hemorrhoids. The patients reported being unaware of colorectal cancer as a possibility and held misconceptions about what the symptoms could mean. By the time they received a correct diagnosis, the cancer had often progressed further than it might have with earlier investigation.6PubMed Central. “Just Hemorrhoids, Not Cancer”: Perceptions of Colorectal Cancer Among Thai Colorectal Cancer Patients
This does not mean that every person with bleeding hemorrhoids has cancer. The vast majority do not. But the symptom profiles overlap enough that self-diagnosis is risky. Bright red blood on toilet paper is a classic hemorrhoid sign, but it can also indicate a polyp or a low rectal tumor. Changes in stool caliber, unexplained weight loss, or bleeding that persists despite conservative treatment are all signals that warrant investigation. The point is not to panic but to get an actual diagnosis. Once a doctor confirms that the problem is hemorrhoids and nothing else, the decision about whether and how aggressively to treat them becomes a much more relaxed conversation.
How Hemorrhoids Progress If Left Alone
Hemorrhoids are graded on a four-tier scale based on how much the internal cushions prolapse. At grade 1, the tissue is swollen but stays inside the anal canal. At grade 2, it protrudes during straining but retracts on its own. At grade 3, it protrudes and must be pushed back in manually. At grade 4, the tissue stays outside permanently and cannot be reduced.
Not every hemorrhoid marches steadily through these stages. Some people sit at grade 1 or 2 for years without meaningful progression, especially if they maintain soft stools and avoid excessive straining. But the general trajectory without intervention tends to be in one direction. The tissue stretches, the supporting connective tissue weakens, and gravity and repeated pressure do their work. A hemorrhoid that prolapses occasionally during a bout of constipation may, over years, begin to prolapse during routine bowel movements and eventually stay prolapsed most of the time.
This matters for treatment because the options narrow as the grade advances. Early-stage hemorrhoids respond well to dietary changes, topical treatments, and office-based procedures like rubber band ligation. By the time hemorrhoids reach grade 3 or 4, surgery becomes far more likely. A study comparing outcomes across surgical techniques found that patients with combined internal and external disease who eventually required surgery had good outcomes, but the procedures are more involved and recovery is longer than what earlier intervention would have required.7PubMed Central. Latest Research Trends on the Management of Hemorrhoids Delaying treatment does not remove the problem from your to-do list. It moves it to a page that involves a surgeon, anesthesia, and a more painful recovery.
Hemorrhoids During Pregnancy and Postpartum
Pregnancy creates a perfect storm for hemorrhoid development and flares. Increased blood volume, pressure from the growing uterus on pelvic veins, hormonal changes that relax vein walls, and constipation from iron supplements all contribute. Research has found that the third trimester is the most vulnerable period, accounting for roughly two-thirds of pregnancy-related hemorrhoid and fissure cases, with about a fifth occurring in the second trimester and around 11% developing in the first month after delivery.8Journal of Pharmaceutical Research International. Occurrence of Hemorrhoids and Anal Fissures through Pregnancy and Postpartum
For pregnant and postpartum people, the question of whether to treat becomes more nuanced. Many medications and procedures that are routine for the general population are either contraindicated during pregnancy or best deferred until after delivery. Conservative measures like fiber supplementation, sitz baths, and stool softeners are the standard approach. The good news is that hemorrhoids that develop primarily because of pregnancy-related pressure often improve substantially in the weeks after delivery as pelvic congestion decreases. However, if the tissue has been significantly stretched or damaged during pregnancy and delivery, the hemorrhoids can persist and become a chronic issue that eventually requires more active treatment.
The Financial Cost of Delayed Treatment
Beyond the personal cost, there is a financial dimension to hemorrhoid avoidance. An analysis of U.S. employer-insured claims from 2014 estimated that roughly 1.4 million people sought outpatient care for hemorrhoids that year, at a total annual cost approaching $800 million. That figure includes physician visits, outpatient facility charges, and prescription medications.9PubMed. Burden and Cost of Outpatient Hemorrhoids in the United States Employer-Insured Population, 2014
What those aggregate numbers hint at is that hemorrhoid care is not cheap, and the later you enter the treatment pipeline, the more expensive your care tends to be. An office visit for dietary counseling and a prescription for a topical cream is a fraction of the cost of an emergency room visit for a thrombosed hemorrhoid. And an emergency room visit is a fraction of the cost of a surgical hemorrhoidectomy with anesthesia, facility fees, and several weeks of lost productivity during recovery. People who avoid care out of a desire to save money or time often end up spending more of both.
When Hemorrhoids Coexist with Other Anorectal Problems
Hemorrhoids rarely exist in isolation. Anal fissures, which are small tears in the lining of the anal canal, are frequently found alongside hemorrhoids and share many of the same triggers: hard stools, straining, and chronic diarrhea. Perianal fistulas, though less common, can also develop in the same anatomical neighborhood. These conditions all produce overlapping symptoms like pain, bleeding, and itching, which makes self-diagnosis even less reliable than it would be for hemorrhoids alone.10PubMed Central. Benign anorectal disease: hemorrhoids, fissures, and fistulas
The practical implication is that treating one condition while ignoring another often produces incomplete relief. A person who takes hemorrhoid cream for what turns out to be an anal fissure may get partial improvement from the lubricating effect of the cream but never fully heal because the fissure requires different management, often including agents that relax the internal sphincter. Conversely, someone with both hemorrhoids and a fissure who only gets the fissure treated may continue to have bleeding from the untreated hemorrhoidal tissue. A comprehensive evaluation sorts out what is contributing to what, which matters for getting better rather than just getting by.
People on Blood Thinners and Other High-Risk Groups
Certain populations face higher stakes when hemorrhoids go untreated. People taking anticoagulant medications are at particular risk because even minor hemorrhoidal bleeding can be difficult to control and may become clinically significant over time. The Olmsted County study on hemorrhoid-related anemia noted that several patients in the cohort had impaired coagulation, which likely contributed to their progression from nuisance bleeding to frank anemia.2PubMed. Evaluation of anemia caused by hemorrhoidal bleeding
People with liver disease and portal hypertension can develop anorectal varices that are sometimes confused with ordinary hemorrhoids. The management and risks of these two conditions are different, and treating anorectal varices as if they were simple hemorrhoids can lead to dangerous bleeding. This is another argument for professional evaluation rather than home management, especially if you have a known liver condition.
Immunocompromised individuals, including those on chemotherapy or immunosuppressive drugs after organ transplantation, face an elevated risk of infection from hemorrhoidal tissue that becomes ulcerated or necrotic. For these groups, “watching and waiting” carries a higher baseline risk than it does for a generally healthy person, and earlier intervention is usually recommended.
