Why Do I Get Hemorrhoids? Hemorrhoids, also known as piles, are a common ailment that can cause significant discomfort. At WHY.EDU.VN, we aim to provide clear, comprehensive answers to your health questions, offering solutions and insights to improve your well-being. Let’s explore the reasons behind hemorrhoid development, effective treatments, and preventive measures, focusing on anorectal disorders and rectal bleeding to alleviate your worries and guide you toward optimal health.
1. What Are Hemorrhoids?
Hemorrhoids are swollen veins in the anus and lower rectum, similar to varicose veins. While everyone has hemorrhoidal tissue as part of their normal anatomy, these veins can become enlarged and inflamed, leading to the uncomfortable condition known as hemorrhoids. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), about one in 20 Americans have hemorrhoids. This common problem can affect individuals of all ages, but it is most prevalent among adults aged 45 to 65. Hemorrhoids are often categorized into two main types: internal and external.
1.1 Internal Hemorrhoids
Internal hemorrhoids develop inside the rectum and are typically painless, even when they bleed. You might notice bright red blood on toilet paper or in the toilet bowl after a bowel movement. These hemorrhoids can prolapse, meaning they extend through the anus, causing irritation and discomfort.
1.2 External Hemorrhoids
External hemorrhoids form under the skin around the anus and are generally more uncomfortable than internal ones. The skin covering these hemorrhoids can become irritated, leading to itching, swelling, and pain. If a blood clot forms inside an external hemorrhoid, it can cause severe pain and is known as a thrombosed hemorrhoid. The Mayo Clinic states that thrombosed external hemorrhoids often require medical intervention to relieve the pain.

2. Common Causes of Hemorrhoids
Several factors can contribute to the development of hemorrhoids. Understanding these causes can help you take preventive measures and make informed lifestyle choices. Here are some of the most common causes:
2.1 Straining During Bowel Movements
Straining during bowel movements increases pressure in the rectum and anus, which can lead to swollen and inflamed veins. This is a primary cause of hemorrhoids, especially in individuals who suffer from chronic constipation. According to a study published in the American Journal of Gastroenterology, prolonged straining can weaken the supporting tissues around the anal canal, contributing to hemorrhoid development.
2.2 Chronic Constipation and Diarrhea
Both chronic constipation and diarrhea can irritate and inflame the veins in the rectum and anus. Constipation causes straining, while diarrhea can lead to frequent bowel movements that irritate the anal tissues. The National Health Service (NHS) recommends maintaining a balanced diet and staying hydrated to prevent both conditions.
2.3 Prolonged Sitting
Sitting for extended periods, especially on the toilet, can increase pressure on the veins in the anus and rectum. This can interfere with blood flow, causing the veins to swell. Experts at the Cleveland Clinic advise against spending too much time on the toilet and recommend taking breaks to avoid prolonged pressure on the anal area.
2.4 Pregnancy
Pregnancy often leads to hemorrhoids due to the increased pressure from the growing uterus on the pelvic veins. Hormonal changes during pregnancy can also contribute to the swelling of these veins. The American Pregnancy Association notes that hemorrhoids are common during pregnancy, particularly in the third trimester, and usually resolve after childbirth.
2.5 Obesity
Being overweight or obese can increase the risk of developing hemorrhoids. Excess weight puts additional pressure on the veins in the rectum and anus, leading to inflammation and swelling. A study in the Diseases of the Colon & Rectum journal found a significant correlation between obesity and the prevalence of hemorrhoids.
2.6 Age
As we age, the tissues supporting the veins in the rectum and anus can weaken, making them more prone to swelling and inflammation. This is why hemorrhoids are more common in older adults. The American Society of Colon and Rectal Surgeons (ASCRS) states that about half of adults over age 50 experience hemorrhoids.
2.7 Genetics
Genetics can play a role in the development of hemorrhoids. If your parents or close relatives have a history of hemorrhoids, you may be more likely to develop them as well. While the exact genetic mechanisms are not fully understood, a family history of venous disorders can increase your susceptibility.
2.8 Anal Intercourse
Anal intercourse can increase the risk of developing hemorrhoids due to the added pressure and friction on the anal tissues. This can cause inflammation and swelling of the veins in the area. It is important to practice safe and gentle anal sex to minimize the risk of developing hemorrhoids.
2.9 Heavy Lifting
Repeatedly lifting heavy objects can increase pressure in the abdomen and rectum, contributing to the development of hemorrhoids. This is particularly common among individuals who work in jobs that require frequent heavy lifting. Proper lifting techniques and breaks can help reduce the risk.
3. Symptoms of Hemorrhoids
Recognizing the symptoms of hemorrhoids is crucial for early diagnosis and treatment. The symptoms can vary depending on the type and severity of the hemorrhoids. Here are some common symptoms:
3.1 Bleeding
Bleeding during bowel movements is a common symptom of internal hemorrhoids. You may notice bright red blood on the toilet paper, in the toilet bowl, or on the stool. The bleeding is usually painless but can be alarming.
3.2 Itching
Itching around the anus is a frequent symptom, especially with external hemorrhoids. The irritation is caused by inflammation and can be exacerbated by wiping. According to the American Academy of Dermatology, gentle cleansing and patting the area dry can help relieve itching.
3.3 Pain and Discomfort
Pain and discomfort are more common with external hemorrhoids, particularly when they are thrombosed. The pain can be intense and may worsen during bowel movements or prolonged sitting. Over-the-counter pain relievers and topical creams can help manage the pain.
3.4 Swelling
Swelling around the anus is a visible sign of external hemorrhoids. The area may feel tender and appear red or purple. Applying ice packs can help reduce swelling and provide temporary relief.
3.5 Prolapse
Internal hemorrhoids can prolapse through the anus, causing a lump or bulge that you can feel. Prolapsed hemorrhoids can be painful and may require manual repositioning. In some cases, a prolapsed hemorrhoid may retract on its own.
3.6 Fecal Leakage
In severe cases, hemorrhoids can cause fecal leakage, leading to soiling of underwear. This is more common with large, prolapsed internal hemorrhoids. Proper hygiene and medical treatment can help manage this symptom.
4. Diagnosing Hemorrhoids
A medical professional can typically diagnose hemorrhoids through a physical examination and a review of your medical history. Here are some common diagnostic methods:
4.1 Physical Examination
A physical examination usually involves a visual inspection of the anus and surrounding area. The doctor will look for signs of external hemorrhoids, swelling, and irritation. They may also perform a digital rectal exam, where a gloved, lubricated finger is inserted into the rectum to feel for internal hemorrhoids or other abnormalities.
4.2 Anoscopy
An anoscopy involves using an anoscope, a short, rigid tube with a light, to view the anal canal. This allows the doctor to examine the lining of the anus and rectum more closely and identify internal hemorrhoids.
4.3 Sigmoidoscopy and Colonoscopy
If there is evidence of rectal bleeding or other gastrointestinal symptoms, the doctor may recommend a sigmoidoscopy or colonoscopy to rule out other conditions, such as colorectal polyps or cancer. Sigmoidoscopy examines the lower part of the colon, while colonoscopy examines the entire colon. The National Cancer Institute recommends regular screening for colorectal cancer, especially for individuals over age 45.
5. Treatment Options for Hemorrhoids
There are various treatment options available for hemorrhoids, ranging from home remedies to medical procedures. The best approach depends on the severity of the symptoms and the type of hemorrhoids.
5.1 Home Remedies
Many people find relief from hemorrhoid symptoms through simple home remedies. These include:
-
High-Fiber Diet: Eating a diet rich in fiber can soften stools and make them easier to pass, reducing straining. Good sources of fiber include fruits, vegetables, whole grains, and legumes.
-
Hydration: Drinking plenty of water helps keep stools soft and prevents constipation. Aim for at least eight glasses of water per day.
-
Sitz Baths: Soaking in a warm sitz bath for 10-15 minutes several times a day can relieve itching, pain, and spasms of the sphincter muscle.
-
Topical Creams and Ointments: Over-the-counter hemorrhoid creams and ointments containing ingredients like hydrocortisone or witch hazel can help reduce inflammation and relieve itching and pain.
-
Ice Packs: Applying ice packs to the anal area can help reduce swelling and pain.
-
Stool Softeners: Using stool softeners can make it easier to pass stools and reduce straining.
5.2 Medical Procedures
If home remedies do not provide sufficient relief, several medical procedures are available:
-
Rubber Band Ligation: This is a common procedure for internal hemorrhoids, where a small elastic band is placed around the base of the hemorrhoid to cut off its blood supply. The hemorrhoid shrinks and falls off within a few days.
-
Sclerotherapy: This involves injecting a chemical solution into the hemorrhoid to shrink it. Sclerotherapy is often used for bleeding internal hemorrhoids.
-
Infrared Coagulation: This procedure uses infrared light to create heat that causes the hemorrhoid to shrink.
-
Hemorrhoidectomy: This is a surgical procedure to remove hemorrhoids. It is typically reserved for severe cases that do not respond to other treatments.
-
Stapled Hemorrhoidopexy: This procedure uses a stapling device to reposition the hemorrhoids in their normal location. It is less painful than a traditional hemorrhoidectomy.
6. Preventive Measures
Preventing hemorrhoids involves making lifestyle changes to reduce pressure on the veins in the rectum and anus. Here are some preventive measures you can take:
6.1 Maintain a High-Fiber Diet
Eating a diet rich in fiber is one of the most effective ways to prevent hemorrhoids. Fiber adds bulk to the stool, making it easier to pass and reducing straining. The Academy of Nutrition and Dietetics recommends consuming at least 25-30 grams of fiber per day.
6.2 Stay Hydrated
Drinking plenty of water helps keep stools soft and prevents constipation. Aim for at least eight glasses of water per day.
6.3 Avoid Straining
Avoid straining during bowel movements. If you are unable to pass stool easily, try using a stool softener or increasing your fiber intake.
6.4 Limit Sitting Time
Avoid sitting for prolonged periods, especially on the toilet. Take breaks to stand up and move around to reduce pressure on the anal area.
6.5 Exercise Regularly
Regular exercise can help improve bowel function and prevent constipation. Aim for at least 30 minutes of moderate-intensity exercise most days of the week.
6.6 Maintain a Healthy Weight
Maintaining a healthy weight can reduce pressure on the veins in the rectum and anus. If you are overweight or obese, losing weight can help prevent hemorrhoids.
6.7 Use Proper Lifting Techniques
When lifting heavy objects, use proper techniques to avoid straining your abdominal and rectal muscles. Keep your back straight and lift with your legs.
6.8 Consider a Footstool
Using a small footstool while sitting on the toilet can help align your colon and make it easier to pass stool without straining.
7. Hemorrhoids and Pregnancy: What to Expect
Hemorrhoids are common during pregnancy due to increased pressure on the pelvic veins and hormonal changes. Here’s what pregnant women should expect:
7.1 Increased Pressure
The growing uterus puts pressure on the pelvic veins, leading to swelling and inflammation.
7.2 Hormonal Changes
Hormonal changes during pregnancy can cause the veins to relax, making them more prone to swelling.
7.3 Constipation
Constipation is common during pregnancy, which can exacerbate hemorrhoids.
7.4 Management Strategies
- Dietary Changes: Eating a high-fiber diet and staying hydrated can help prevent constipation.
- Sitz Baths: Soaking in a warm sitz bath can relieve pain and itching.
- Topical Creams: Over-the-counter hemorrhoid creams can provide temporary relief.
- Gentle Exercise: Regular, gentle exercise can improve bowel function.
- Consult Your Doctor: If symptoms are severe, consult your doctor for additional treatment options.
8. Complications of Hemorrhoids
While hemorrhoids are generally not dangerous, they can lead to complications if left untreated. Here are some potential complications:
8.1 Anemia
Chronic bleeding from hemorrhoids can lead to anemia, a condition where there are not enough red blood cells to carry oxygen to the body’s tissues.
8.2 Thrombosed Hemorrhoid
A blood clot can form inside an external hemorrhoid, causing severe pain and swelling. This condition requires prompt medical treatment.
8.3 Strangulated Hemorrhoid
If a prolapsed internal hemorrhoid becomes trapped outside the anus, it can become strangulated, meaning its blood supply is cut off. This can lead to severe pain and tissue damage.
8.4 Infection
In rare cases, hemorrhoids can become infected, leading to pain, swelling, and fever.
8.5 Skin Tags
After a thrombosed external hemorrhoid resolves, it can leave behind a skin tag, a small flap of skin that can be irritating and difficult to clean.
9. When to See a Doctor
It is important to see a doctor if you experience any of the following symptoms:
- Rectal bleeding, especially if it is persistent or heavy
- Pain or discomfort around the anus
- Swelling or a lump near the anus
- Changes in bowel habits
- Fecal leakage
These symptoms can also be indicative of other conditions, such as colorectal polyps or cancer, so it is important to get a proper diagnosis.
