Zepbound (tirzepatide) is an FDA-approved medication for chronic weight management that works by activating GIP and GLP-1 receptors to reduce appetite and slow gastric emptying. While does Zepbound cause hemorrhoids is a common concern among patients, hemorrhoids are not listed as a direct side effect in clinical trials or FDA labeling. However, Zepbound's gastrointestinal effects—including constipation in 16-17% and diarrhea in 18-24% of patients—may indirectly increase hemorrhoid risk through straining or anal irritation. Understanding this relationship helps patients take preventive measures while benefiting from this weight management therapy.
Quick Answer: Zepbound does not directly cause hemorrhoids, but its common gastrointestinal side effects—constipation and diarrhea—may indirectly increase hemorrhoid risk through straining or anal irritation.
Zepbound (tirzepatide) is a prescription medication approved by the FDA for chronic weight management in adults with obesity (BMI ≥30 kg/m²) or overweight (BMI ≥27 kg/m²) with at least one weight-related comorbid condition. It must be used in conjunction with a reduced-calorie diet and increased physical activity. Zepbound is a dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist administered as a once-weekly subcutaneous injection.
The mechanism of action involves activating both GIP and GLP-1 receptors, which reduces appetite, slows gastric emptying, and improves glycemic control. These effects contribute to significant weight loss but also result in predictable gastrointestinal side effects.
The most common adverse effects of Zepbound include:
Nausea (24-29%, dose-dependent)
Diarrhea (18-24%, dose-dependent)
Vomiting (8-12%, dose-dependent)
Constipation (16-17%, dose-dependent)
Abdominal pain and dyspepsia
Decreased appetite
These gastrointestinal effects are typically most pronounced during dose initiation and escalation, often improving over time as the body adjusts to the medication. Most gastrointestinal adverse reactions are mild to moderate in severity.
Important safety information: Zepbound carries a boxed warning for risk of thyroid C-cell tumors and is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN2). Other serious risks include pancreatitis, gallbladder disease, acute kidney injury, and hypersensitivity reactions. Patients with severe gastrointestinal disease should use caution with this medication.
Understanding how these side effects may indirectly contribute to other conditions, such as hemorrhoids, is important for comprehensive patient care and counseling. Patients should be informed about the expected side effect profile before initiating therapy.

There is no direct link established between Zepbound and hemorrhoids in the FDA prescribing information or clinical trial data. Hemorrhoids are not listed as a recognized adverse effect of tirzepatide in the product labeling, and the pivotal SURMOUNT clinical trials did not identify hemorrhoids as a specific safety signal.
However, it is important to distinguish between direct causation and indirect risk factors. While Zepbound does not directly cause hemorrhoids through its pharmacological mechanism, the medication's gastrointestinal side effects may create conditions that increase the risk of developing or exacerbating hemorrhoidal disease.
Hemorrhoids develop when increased pressure is applied to the venous cushions in the anal canal. Common contributing factors include:
Chronic constipation and straining during bowel movements
Prolonged sitting on the toilet
Diarrhea and frequent bowel movements
Increased intra-abdominal pressure
Given that Zepbound commonly causes both constipation (in approximately 16-17% of patients) and diarrhea (in about 18-24% of patients), these gastrointestinal effects could theoretically contribute to hemorrhoid development or worsening in susceptible individuals. The relationship is indirect rather than a direct pharmacological effect of the medication itself.
Patients with pre-existing hemorrhoids or risk factors for hemorrhoidal disease should discuss these concerns with their healthcare provider before starting Zepbound. Proactive management of gastrointestinal side effects may help minimize any potential indirect risk to anorectal health.
The gastrointestinal side effects of Zepbound stem from its mechanism as a GIP/GLP-1 receptor agonist, which slows gastric emptying and alters bowel motility. This effect may attenuate somewhat with chronic use. Understanding these effects helps clarify the potential indirect pathway to hemorrhoid development.
Constipation is reported in approximately 16-17% of Zepbound users and represents a significant concern for anorectal health. When stool remains in the colon longer, it becomes harder and more difficult to pass. This may lead to straining during defecation, which increases intra-abdominal and venous pressure in the hemorrhoidal plexus. Repeated straining over time can cause the supporting tissues to stretch and weaken, potentially leading to hemorrhoid formation or prolapse of existing hemorrhoids.
Diarrhea, affecting about 18-24% of patients, presents a different but equally relevant risk. Frequent loose stools and repeated bowel movements can irritate the anal canal and perianal skin. The increased frequency of defecation may also lead to prolonged toilet sitting and incomplete evacuation sensations, both of which may contribute to venous congestion in the anorectal area.
Abdominal discomfort and bloating may cause patients to alter their dietary habits, potentially reducing fiber intake or fluid consumption, which can worsen constipation. Additionally, nausea and decreased appetite may lead to inadequate hydration, further contributing to hard stools.
The delayed gastric emptying caused by Zepbound, while beneficial for weight loss and glycemic control, can disrupt normal bowel patterns. Some patients may experience alternating constipation and diarrhea, which could create a cycle of irritation and pressure changes in the anorectal region. This variability in bowel habits may be particularly problematic for individuals with pre-existing hemorrhoidal disease or other anorectal conditions.
It's important to note that gastrointestinal side effects are often dose-dependent and may be managed through appropriate dose titration under healthcare provider supervision.
Proactive management of gastrointestinal side effects is essential for patients taking Zepbound to minimize the indirect risk of hemorrhoid development. The following evidence-based strategies can help maintain healthy bowel function and reduce anorectal pressure.
Dietary modifications:
Gradually increase dietary fiber intake to 25-35 grams daily through whole grains, fruits, vegetables, and legumes
Maintain adequate hydration (aim for pale yellow urine as an indicator of proper hydration)
Avoid excessive caffeine and alcohol, which can contribute to dehydration
Consider a fiber supplement (psyllium, methylcellulose) if dietary intake is insufficient, starting with a low dose and increasing gradually
Bowel habit optimization:
Respond promptly to the urge to defecate rather than delaying
Avoid prolonged sitting on the toilet (limit to 5 minutes or less)
Do not strain during bowel movements; if stool is difficult to pass, try again later
Consider a footstool to elevate feet during defecation, which may help optimize the anorectal angle
Lifestyle measures:
Engage in regular physical activity, which promotes healthy bowel motility
Avoid prolonged sitting; take breaks to stand and move throughout the day
Maintain a healthy weight loss pace as recommended by your healthcare provider
Medical management when needed:
If constipation persists despite dietary measures, discuss with your healthcare provider the use of polyethylene glycol (PEG) as a first-line laxative. For diarrhea, your provider may recommend dose adjustment or temporary symptomatic treatment. Your healthcare provider may also consider slowing or pausing dose escalation if gastrointestinal symptoms are severe.
Proper perianal hygiene using gentle cleansing and avoiding harsh toilet paper can also protect the anal area. These preventive strategies should be implemented from the start of Zepbound therapy rather than waiting for problems to develop.
Patients taking Zepbound should maintain open communication with their healthcare provider regarding gastrointestinal symptoms and any anorectal concerns. Certain symptoms warrant prompt medical evaluation to prevent complications or identify conditions requiring specific treatment.
Contact your healthcare provider if you experience:
Persistent constipation lasting more than three days despite dietary modifications and adequate hydration
Severe or persistent diarrhea (more than six loose stools daily or lasting beyond 48 hours)
Rectal bleeding, even if minor, particularly if bright red blood is noted on toilet paper or in the toilet bowl
Black, tarry, or maroon-colored stools (which may indicate bleeding higher in the digestive tract)
Severe abdominal pain, cramping, or bloating that interferes with daily activities
Signs of dehydration including dark urine, dizziness, or decreased urination
Painful bowel movements or a sensation of incomplete evacuation
Visible or palpable lumps around the anus
Persistent anal pain, itching, or discomfort
Seek immediate medical attention for:
Severe, persistent abdominal pain, especially if radiating to the back (may indicate pancreatitis)
Right upper quadrant pain, fever, or yellowing of skin/eyes (may indicate gallbladder disease)
Heavy rectal bleeding or passage of large amounts of blood
Severe abdominal pain with fever, persistent vomiting, abdominal distension, and inability to pass stool or gas (may suggest bowel obstruction)
Signs of severe dehydration including confusion, rapid heartbeat, or inability to keep fluids down
Important: If you suspect pancreatitis (severe abdominal pain, often radiating to the back, with or without vomiting), stop taking Zepbound immediately and seek urgent medical care.
Your healthcare provider can assess whether gastrointestinal symptoms are typical medication side effects or indicate a need for intervention. They may recommend dose adjustment, additional supportive therapies, or referral to a gastroenterologist or colorectal specialist if hemorrhoids or other anorectal conditions develop. Conservative management is recommended as first-line treatment for most hemorrhoids, but medical evaluation ensures appropriate diagnosis and excludes more serious conditions, especially in adults over 45 or those with risk factors for colorectal cancer.
No, hemorrhoids are not listed as a recognized adverse effect in Zepbound's FDA prescribing information or clinical trial data. However, the medication's gastrointestinal side effects like constipation and diarrhea may indirectly increase hemorrhoid risk in susceptible individuals.
Preventive strategies include gradually increasing dietary fiber to 25-35 grams daily, maintaining adequate hydration, responding promptly to bowel urges, avoiding straining during defecation, and limiting toilet sitting time to 5 minutes or less. Regular physical activity also promotes healthy bowel function.
Contact your healthcare provider for persistent constipation lasting more than three days, severe or persistent diarrhea, any rectal bleeding, severe abdominal pain, painful bowel movements, or visible lumps around the anus. These symptoms may require dose adjustment or additional treatment.
