What Causes Hemorrhoids In Females Pregnancy And More?

Hemorrhoids are swollen veins in the lowest part of the rectum and anus. In females, the most common triggers are pregnancy, childbirth, and chronic constipation. The pressure from a growing uterus, hormonal changes, and straining on the toilet all contribute to these veins swelling and becoming painful.

What Causes Hemorrhoids In Females Pregnancy And More?

Pregnancy is the biggest single cause of hemorrhoids in women. As the uterus expands, it presses directly on the veins that drain blood from the lower body. This pressure slows blood flow and causes the veins in the rectum to swell.

Hormones also play a role. During pregnancy, the body produces more progesterone. This hormone relaxes the walls of blood vessels, which makes them more likely to stretch and bulge. The combination of physical pressure and relaxed vein walls is a direct setup for hemorrhoids.

Constipation is the other major driver. Stool that is hard and dry forces you to strain during bowel movements. Straining increases pressure in the rectal veins. Over time, this repeated pressure pushes the veins outward, forming hemorrhoids. This applies whether you are pregnant or not.

Why Are Hemorrhoids So Common During Pregnancy?

Research consistently shows that hemorrhoids affect a large percentage of pregnant women, particularly in the third trimester. The third trimester is when the uterus is at its largest and pressure on the pelvic veins is highest.

Constipation often worsens during pregnancy for several reasons. The same progesterone that relaxes veins also slows down the digestive tract. Food moves more slowly through the intestines, giving the body more time to absorb water from the stool. The result is harder, drier stool that is harder to pass.

Iron supplements, which many pregnant women take for anemia, can also cause constipation. If you take a prenatal vitamin with iron and notice harder stools, talk to your clinician about whether a different formulation might help.

Does Childbirth Itself Cause Hemorrhoids?

Yes. The second stage of labor — the pushing phase — places enormous pressure on the pelvic floor and rectal veins. Many women who had no hemorrhoids during pregnancy develop them during delivery. Women who already have hemorrhoids often find they become significantly worse after giving birth.

The straining during labor is similar to the straining during constipation, but far more intense and sustained. Forceps deliveries and prolonged pushing are associated with a higher risk of developing hemorrhoids after childbirth.

The good news is that postpartum hemorrhoids often improve within a few weeks. As hormone levels return to normal and the body recovers from delivery, the swelling typically decreases. However, hemorrhoids that developed during pregnancy may take several months to fully resolve, especially if constipation continues.

What Are The Other Causes In Women?

Beyond pregnancy, several other factors can cause hemorrhoids in women. Chronic constipation is the most common non-pregnancy cause. A low-fiber diet leads to hard stools and straining, which directly causes hemorrhoids.

Diarrhea can also be a cause. Frequent loose stools irritate the anal area and can lead to swelling of the veins. Repeated wiping and the acidity of loose stool both contribute to irritation.

Being overweight or obese increases abdominal pressure. This pressure pushes down on the pelvic veins in the same way a pregnant uterus does. Weight gain around the midsection is particularly associated with hemorrhoids.

Sitting for long periods, especially on the toilet, increases pressure on the rectal veins. Spending more than 10 minutes on the toilet is linked to a higher risk. The seated position puts direct pressure on the anal area, and the longer you sit, the more the veins swell.

Age is a factor as well. Hemorrhoids become more common as people get older. The tissues supporting the veins in the rectum weaken with age, making them more prone to bulging.

What Are The Symptoms To Watch For?

Hemorrhoids can be internal or external. Internal hemorrhoids form inside the rectum and often cause no pain. The most common symptom is bright red blood on toilet paper or in the toilet bowl after a bowel movement.

External hemorrhoids form under the skin around the anus. These are the ones that cause itching, burning, and pain. You may feel a tender lump near the anus. External hemorrhoids can also bleed, particularly if you wipe aggressively.

A thrombosed hemorrhoid is a specific type of external hemorrhoid where a blood clot forms inside the swollen vein. This causes sudden, severe pain and a firm, tender lump. Thrombosed hemorrhoids are not dangerous but are very uncomfortable. The pain typically peaks within 48 hours and gradually improves over the following week or two.

If you notice rectal bleeding, it is important to have it evaluated. While hemorrhoids are the most common cause of rectal bleeding, other conditions can cause the same symptom. Colon cancer, anal fissures, and inflammatory bowel disease can all present with bleeding. Your clinician can determine the actual cause.

How Can You Prevent Hemorrhoids?

Prevention focuses on keeping stool soft and avoiding straining. This is the same advice whether you are pregnant or not.

Fiber is the foundation. Adults should aim for about 25 to 30 grams of fiber per day from fruits, vegetables, whole grains, and legumes. Increase fiber gradually to avoid gas and bloating.

Water matters just as much as fiber. Fiber absorbs water to soften stool. If you increase fiber without increasing water, constipation can actually get worse. Aim for 8 to 10 cups of fluid per day, more if you are pregnant or physically active.

Do not delay bowel movements. When you feel the urge to go, go. Waiting allows the colon to absorb more water from the stool, making it harder and more difficult to pass.

Limit time on the toilet. If a bowel movement does not happen within a few minutes, get up and try again later. Do not sit and push. Do not use your phone or a book while on the toilet — this extends sitting time and increases pressure on the veins.

Regular physical activity helps keep the digestive tract moving. Walking, swimming, and prenatal exercise classes are all good options. Even a 20-minute walk after meals can help prevent constipation.

What Treatments Actually Work?

For mild hemorrhoids, home care is usually enough. Warm sitz baths — sitting in a few inches of warm water for 10 to 15 minutes — can relieve pain and itching. You can do this two to three times a day. The warmth increases blood flow to the area and relaxes the sphincter muscle.

Over-the-counter creams and suppositories containing hydrocortisone can reduce inflammation and itching. Use them for short periods only — typically no more than a week — because prolonged use can thin the skin. Witch hazel pads are a gentler option that many women find soothing.

Pain relievers like acetaminophen are safe during pregnancy and can help with discomfort. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen are generally avoided in the third trimester of pregnancy. Always check with your clinician before taking any medication while pregnant.

Stool softeners such as docusate are considered safe during pregnancy and can make bowel movements easier. These do not stimulate the bowel — they simply help water mix into the stool. Bulk-forming laxatives like psyllium are also considered safe and work by adding fiber to the stool.

For persistent or severe hemorrhoids, several in-office procedures exist. Rubber band ligation involves placing a small band around the base of the hemorrhoid to cut off its blood supply. Sclerotherapy involves injecting a chemical solution that shrinks the hemorrhoid. Infrared coagulation uses heat to create scar tissue.

These procedures are generally not performed during pregnancy unless the hemorrhoid is severe and causing significant bleeding. Most clinicians prefer to wait until after delivery. After pregnancy, these options become fully available, and they are effective for hemorrhoids that do not respond to home care.

Hemorrhoidectomy — surgical removal of the hemorrhoid — is reserved for the most severe cases. It is the most effective treatment for large or thrombosed hemorrhoids but has a longer recovery time and more pain afterward.

When Should You See A Doctor?

You should see a clinician if rectal bleeding is heavy, if you pass blood clots, or if the bleeding lasts more than a few days. You should also seek care if you have severe pain that does not improve with home treatment, or if you notice a lump that does not go away after a week.

Changes in bowel habits that last more than a few weeks deserve evaluation. This includes new constipation, diarrhea, or a feeling that the bowel does not empty completely. Unexplained weight loss or fatigue alongside rectal symptoms also warrant a medical visit.

During pregnancy, any significant rectal bleeding should be discussed with your obstetrician. While hemorrhoids are the likely cause, other conditions need to be ruled out. Your clinician can examine you and determine whether further testing is needed.
