Why does anal vein thrombosis occur so frequently after birth?
During pregnancy and especially under the strain of childbirth, there are strong pressure changes in the abdominal and pelvic area. The veins around the anus are heavily stressed. Hormonal changes, increased blood clotting tendency, and pushing during delivery can lead to the formation of a blood clot, an anal vein thrombosis, in the superficial veins of the anus.

Which factors during pregnancy and childbirth promote anal vein thrombosis?
Several factors increase the risk of anal vein thrombosis after birth:
|
Risk factor |
Impact on the anal veins |
|
Hormonal changes |
Increased vascular permeability, weaker connective tissue |
|
Slowed blood flow |
Greater risk of thrombosis due to congested backflow |
|
Strong pressure when pushing |
Sudden venous congestion in the anal area |
|
Weight gain during pregnancy |
Increased strain on the pelvic and anal veins |
|
Prolonged lying down after birth |
Restricted blood circulation in the lower body area |
These factors explain why many women suddenly notice a bluish, painful swelling at the edge of the anus after giving birth. If the anal vein thrombosis does not resolve, or the perianal thrombosis keeps recurring, a visit to the doctor is definitely recommended. For diagnosis and examinations, you can find more information in the blog post about anal vein thrombosis doctor. Here you will also find further information about the causes of anal vein thrombosis.
Is an anal vein thrombosis after childbirth dangerous for the mother or baby?
Although an anal vein thrombosis can be very painful, it is not dangerous—neither for the mother nor the baby. It affects only the superficial veins in the anal area and has no connection to the deep venous system. There is no risk of embolism or serious thrombosis.
However, the thrombosis can affect the new mother during her recovery phase, especially if it makes sitting or breastfeeding difficult. Pain-relieving measures such as sitz baths and CANNEFF® SUP suppositories help make the healing process more comfortable. However, note that CANNEFF® SUP suppositories are not recommended for breastfeeding mothers.

How long does it take to heal an anal vein thrombosis after childbirth?
The healing time depends on the size of the thrombosis. Smaller anal vein thromboses often recede within two to three weeks, while larger ones can take up to six weeks. The pain is strongest in the first few days but decreases over time.
|
Healing phase |
Symptoms |
|
1-3 days |
Severe pain, tight skin, hard swelling |
|
4-7 days |
Pain subsides, swelling remains palpable |
|
2-3 weeks |
Thrombosis begins to recede |
|
4-6 weeks |
Usually complete regression, possibly remaining skin fold (skin tag) |
The healing time can be shortened by anti-inflammatory measures. Especially CANNEFF® SUP suppositories can help as they reduce swelling and support healing. However, note that CANNEFF® SUP suppositories are not recommended for breastfeeding mothers.

What gentle treatment methods are available for new mothers?
The treatment of anal vein thrombosis should be gentle and adapted to the special needs of breastfeeding mothers. The following methods help to relieve symptoms:
Sitz baths with chamomile or oak bark: Relieve pain, have anti-inflammatory effects.
CANNEFF SUP suppositories: CANNEFF® SUP reduce swelling and promote healing.
Heparin-containing ointments: Support blood breakdown but must be coordinated with the doctor if breastfeeding.
High-fiber diet & plenty of fluids: Facilitate bowel movements and prevent straining again.
Soft seat cushions: Relieve the anal area and reduce pressure pain.

How can you distinguish an anal vein thrombosis after childbirth from hemorrhoids?
Anal venous thromboses are often confused with hemorrhoids, as both conditions frequently occur after childbirth. However, there are crucial differences:
|
Feature |
Anal vein thrombosis |
Hemorrhoids |
|
Pain |
Very strong, stabbing |
Usually mild to moderate, itching |
|
Color of the swelling |
Bluish-red |
Skin-colored or reddish |
|
Location |
Directly at the edge of the anus |
Internal, only visible externally in late stages |
|
Bleeding |
Rare, dark blood |
Common, bright red blood |
|
Regression |
After a few weeks |
Can persist or enlarge |
Hemorrhoids are generally less painful, while an anal venous thrombosis is especially painful in the first few days. Read more here about the symptoms of anal venous thrombosis, or about bleeding as a symptom of anal thrombosis.
