Hemorrhoids, Depression & Anxiety: A New Study Reveals the Surprising Connection

Depression & Anxiety Symptom Networks in Hemorrhoid Patients: What the UK Biobank Study Reveals

If you’re managing hemorrhoids, mental health might not appear on your radar first—but it should. A new open‑access study titled “Depression and anxiety symptom networks in hemorrhoid patients: evidence from the UK Biobank” (2025) sheds important light on how depressive and anxious symptoms interrelate in people with hemorrhoidal disease, and how these relationships differ across subgroups.

In this article, I’ll break down what the researchers found, why it matters, and how you (or your loved one) can use this knowledge to support mental as well as physical well‑being while coping with hemorrhoids.

Why this study matters

• Hemorrhoidal disease is common and often disruptive to quality of life—pain, bleeding, itching, difficulty sitting.
• But physical symptoms rarely happen in isolation. Psychological stress, low mood, anxiety, and worry frequently accompany chronic health issues.
• Traditional research often treats depression and anxiety as “black box” conditions (you score a total, and that’s it). This study takes a more granular, symptom‑level approach using network analysis to see which individual symptoms may act as “bridges” between depression and anxiety in hemorrhoid patients.
• By pinpointing key symptoms, more targeted psychological support or therapy may be possible (rather than a generic “depression” label).

What they did: Methods in brief

• The study used UK Biobank data, focusing on 10,482 participants identified as having hemorrhoidal disease. BioMed Central
• Participants completed standard depression and anxiety instruments: the PHQ‑9 and GAD‑7.
• The authors built a Gaussian graphical model (GGM) to represent the “network” of symptoms—i.e. how each symptom (sad mood, insomnia, worry, restlessness, etc.) connects to others.
• They used EBIC graphical lasso regularization (a statistical method to reduce overfitting) and assessed centrality metrics (strength, betweenness, closeness) to see which symptoms are most “influential” in the network.
• They also tested whether the symptom network structure varied by gender, smoking history, age, and time intervals, via Network Comparison Test (with bootstrap iterations). BioMed Central+1

What they found: Key symptoms and gender differences

Core findings

• The symptom network was stable (CS coefficient = 0.75) — meaning the results are statistically reliable. BioMed Central
• Two symptoms stood out as bridges connecting depression and anxiety domains:
  • “Sad mood” (a core depressive symptom) showed high strength (i.e. strong connections to many other symptoms). BioMed Central
  • “Too much worry” (an anxiety symptom) had high betweenness (i.e. lies on many shortest paths between other symptoms). BioMed Central+1
• In other words: low mood and excessive worry are key drivers binding depression and anxiety in people with hemorrhoids.

Gender differences

• Networks for men and women differed both in global strength and structure. BioMed Central+1
• Women’s networks showed stronger emotion‑cognition connections (e.g. sadness linking more tightly to cognitive symptoms like guilt or worthlessness).
• Men’s symptom networks emphasized somatic‑behavioral links (e.g. symptoms like appetite change or psychomotor behaviors).
• For example, in women, the “anhedonia (loss of interest) – sad mood” edge was stronger, whereas in men, the “appetite – motor symptoms” link was more pronounced. ISPOR.org

Other subgroup comparisons

• The authors analyzed other subgroups (smoking status, age groups, time intervals) but found no significant structural differences across those groups. BioMed Central
• That suggests the core symptom interconnections are relatively robust across these demographics in hemorrhoid patients.

What this means (and what it doesn’t)

Interpretations

• The findings suggest a symptom‑based map of how depression and anxiety interweave in patients with hemorrhoids.
• Sad mood and excessive worry emerge as plausible targets: interventions that reduce persistent worry or lift mood might have ripple effects across many symptoms.
• In clinical or therapeutic settings, this could justify gender‑tailored approaches: women might benefit more from emotion‑cognitive therapy, men from behavioral activation or somatic strategies.

Caveats & limitations

• The study is cross-sectional in symptom data: it shows associations, not causal directionality among symptoms.
• The sample is limited by UK Biobank characteristics (largely White European ancestry, certain age ranges).
• Hemorrhoid “status” is based on self-report or medical record designation in Biobank — details about severity, treatment status, recurrence, etc., may be lacking.
• The network approach is fairly new in psychopathology; individual symptom dynamics can vary across people, even if group-level results are suggestive.

Broader context: Hemorrhoids, mental health, and bidirectional risk

This UK Biobank study is part of growing evidence that mental health and hemorrhoidal disease may be mutually reinforcing.

• A recent Mendelian randomization (genetic) study found bidirectional causal associations between depression and hemorrhoidal disease: genetically higher depression risk modestly increased hemorrhoid risk, and vice versa. PMC
• That suggests people with depression may be more prone to develop hemorrhoids (perhaps via lifestyle, gut motility, inflammation, or pain perception), and hemorrhoid disease itself may feed back into mood.
• So the network study’s findings offer a phenotypic snapshot of anxiety/depression symptom structure in those already with hemorrhoids—adding nuance to the “which comes first” question.

Practical takeaways for hemorrhoid patients

Even though this is research, not a treatment guide, I see several useful implications if you’re managing hemorrhoids and psychological stress or mood symptoms:

1. Don’t dismiss mood or worry as “just stress” of having hemorrhoids. Persistent sadness or worry may be integral to how your body is coping.
2. Targeted psychological support may help more than general “stress reduction.” Because sad mood and worry are central nodes, techniques specifically addressing rumination, negative thinking, cognitive restructuring, or worry interruption could have “knock‑on” benefits across other symptoms.
3. Tailor your approach to your style and gender. If you identify as female (or tend to engage more in inward emotional processing), therapies that address cognition–emotion links may be more helpful. If you lean toward somatic symptoms (appetite, sleep, behavior), behavioral activation or lifestyle tweaks (activity, diet, gut health) may give extra benefit.
4. Integrate psychological care into hemorrhoid management. Ask your colorectal surgeon or proctologist whether they collaborate with mental health professionals. Persistent mood symptoms deserve attention, just like pain, bleeding, or recurrence.
5. Watch for red flags. If sadness, anxiety, or irritability become overwhelming, impair daily function, or accompany suicidal thoughts, see a mental health provider promptly.
