Hemorrhoid Treatment in Pregnant Women
Start with dietary fiber (30 g/day), adequate hydration, and stool softeners (polyethylene glycol or lactulose), and if symptoms persist, use hydrocortisone foam which has been proven safe in pregnancy. 1
Initial Conservative Management
The foundation of hemorrhoid treatment during pregnancy is preventing constipation and straining, which are the primary aggravating factors. According to the 2024 AGA guidelines, hemorrhoids affect approximately 80% of pregnant women, most commonly in the third trimester due to compression of the rectum by the gravid uterus 1.
First-Line Dietary and Lifestyle Modifications
- Increase dietary fiber to 30 g/day through fruits, vegetables, whole grains, and legumes 1
- Adequate fluid intake, particularly water, to soften stools
- Avoid prolonged sitting on the toilet and straining during bowel movements 1
- Use relaxation techniques and allow ample time for bowel movements
Safe Pharmacologic Options
Bulk-forming agents are the safest option:
- Psyllium husk or methylcellulose - safe due to lack of systemic absorption 1
- Psyllium is preferred as it improves stool viscosity and transit time beyond just bulk-forming
Osmotic laxatives are also safe:
- Polyethylene glycol or lactulose can be administered safely during pregnancy 1
- Note: May cause maternal bloating
Avoid stimulant laxatives - conflicting safety data 1
Topical Treatment for Symptomatic Relief
Hydrocortisone foam is safe and effective: A prospective study of 204 patients treated with hydrocortisone foam for hemorrhoids in the third trimester showed no adverse events compared with placebo 1. This is the only topical treatment with strong evidence in pregnancy.
Other topical options with limited data include anesthetics, astringents (witch hazel), and vasoactive agents 2, but hydrocortisone foam has the best evidence.
When Conservative Treatment Fails
Most hemorrhoids during pregnancy should be managed conservatively, with procedural interventions deferred until postpartum 2. However, if symptoms persist after delivery or if the woman is planning further pregnancies, standard treatments like rubber band ligation or infrared coagulation can be considered 2.
Special Situation: Acute Thrombosed External Hemorrhoids
Surgical incision and drainage is the treatment of choice for acute thrombosed external hemorrhoids causing severe pain 2, 3. A 2024 study demonstrated that:
- Local excision is superior to thrombectomy (7% vs 38% re-thrombosis rate) 3
- Surgery provides faster pain relief compared to conservative management 3
- Both approaches are safe for mother and fetus 3
Conservative management (pain control, stool softeners, topical analgesics) is appropriate if presentation is >72 hours after acute thrombosis 4.
Important Caveats
- Only 0.2% of pregnant women require urgent hemorrhoidectomy for incarcerated prolapsed hemorrhoids 5
- Symptoms often persist postpartum, causing significant discomfort 6
- Topical steroids should not be used for more than 2 weeks at a time 2
- Most pregnant women (93.2%) use topical ointments, with only 1.8% requiring procedures or surgery during pregnancy 7
Clinical Algorithm
- All pregnant women with hemorrhoids: Start fiber (30 g/day) + hydration + avoid straining
- If constipated: Add psyllium husk or polyethylene glycol
- If symptomatic (itching, discomfort, bleeding): Add hydrocortisone foam
- If acute thrombosed external hemorrhoid with severe pain: Consider surgical excision (local excision preferred over thrombectomy)
- If persistent symptoms postpartum: Consider rubber band ligation or infrared coagulation
