Hemorrhoids, also known as piles, are a common condition that affects millions of people worldwide. While they are often not serious, they can cause discomfort, pain, and bleeding, significantly impacting your quality of life. Understanding how hemorrhoids develop is the first step towards prevention and effective management. This article delves into the causes, symptoms, and treatments for hemorrhoids, providing you with comprehensive information to address this condition.
What are Hemorrhoids?
Hemorrhoids are swollen veins in the anus and lower rectum, similar to varicose veins. They can develop inside the rectum (internal hemorrhoids) or under the skin around the anus (external hemorrhoids). It’s important to understand that everyone has hemorrhoidal veins as part of their anatomy. These veins become a problem when they swell and become distended.
How Do You Get Hemorrhoids? Key Causes and Risk Factors
The most common cause of hemorrhoids is increased pressure in the lower rectum. This pressure can be caused by a variety of factors, many of which are related to lifestyle and bodily functions. Let’s explore the primary contributors:
1. Straining During Bowel Movements
Excessive straining when trying to have a bowel movement is a leading cause of hemorrhoids. This straining puts significant pressure on the veins in the rectum and anus, leading them to swell and bulge. Straining is often a result of constipation or diarrhea, which can make bowel movements difficult or frequent.
2. Chronic Constipation and Diarrhea
Both chronic constipation and diarrhea can contribute to the development of hemorrhoids. Constipation leads to hard, dry stools that require straining to pass. Conversely, frequent diarrhea can irritate the anal area and also lead to straining and increased pressure.
3. Sitting for Long Periods, Especially on the Toilet
Prolonged sitting, particularly on the toilet, can increase pressure on the veins in the anus and rectum. The longer you sit, the more pressure is exerted, which can hinder blood flow and cause veins to swell. It’s advisable to limit time spent on the toilet and avoid bringing reading material that might extend your stay.
4. Obesity
Excess weight, especially when it is concentrated in the abdominal area, can put extra pressure on the veins in your pelvis and rectum. This increased pressure can contribute to the development of hemorrhoids.
5. Pregnancy
Pregnancy is a common trigger for hemorrhoids. As the uterus grows, it puts pressure on the veins in the pelvis and abdomen. Hormonal changes during pregnancy can also cause hemorrhoidal veins to relax and swell. Additionally, constipation is common during pregnancy, further exacerbating the issue.
6. Low-Fiber Diet
A diet low in fiber can lead to constipation, which, as mentioned earlier, is a major risk factor for hemorrhoids. Fiber adds bulk to your stool, making it softer and easier to pass, reducing the need for straining.
7. Aging
As we age, the tissues supporting the veins in the rectum and anus can weaken and stretch. This makes them more susceptible to swelling and bulging, increasing the risk of hemorrhoids.
8. Heavy Lifting
Regularly lifting heavy objects can also increase pressure in the abdomen and contribute to hemorrhoid development. This is especially true if you are not using proper lifting techniques and are holding your breath while lifting.
9. Anal Intercourse
Anal intercourse can sometimes lead to hemorrhoids due to the direct pressure and potential trauma to the anal veins.
10. Family History
There might be a genetic predisposition to developing hemorrhoids. If other members of your family have experienced hemorrhoids, you may be at a slightly higher risk.
Symptoms of Hemorrhoids
The symptoms of hemorrhoids can vary depending on whether they are internal or external.
Symptoms of External Hemorrhoids:
- Painful swelling or hard lumps around the anus: These are often thrombosed external hemorrhoids, where a blood clot has formed within the hemorrhoid.
- Itching or irritation in the anal region: This is a common symptom due to inflammation and swelling.
- Pain: Especially during bowel movements, sitting, or wiping.
- Bleeding: Usually less common with external hemorrhoids compared to internal ones, but can occur.
Symptoms of Internal Hemorrhoids:
- Painless bleeding during bowel movements: You might notice bright red blood on toilet paper, in the stool, or in the toilet bowl.
- Prolapse: Hemorrhoids may protrude through the anal opening. Initially, they might retract on their own, but over time, they may need to be pushed back in or may remain permanently prolapsed.
- Itching and irritation: Mucus discharge from prolapsed hemorrhoids can cause anal itching.
- Pain: Internal hemorrhoids are typically less painful than external ones unless they become prolapsed and strangulated (blood supply is cut off).
Diagnosis of Hemorrhoids
Diagnosing hemorrhoids typically involves a physical examination and a review of your medical history and symptoms.
Visual and Digital Examination
Your healthcare provider may be able to diagnose external hemorrhoids simply by visual inspection. For internal hemorrhoids, a digital rectal exam is usually performed. This involves your doctor inserting a gloved, lubricated finger into your rectum to feel for any abnormalities, such as swollen veins or growths.
Anoscopy, Proctoscopy, or Sigmoidoscopy
To visualize internal hemorrhoids more clearly, your doctor may use instruments like an anoscope, proctoscope, or sigmoidoscope. These are lighted tubes inserted into the anus and rectum, allowing for a closer examination of the lining and hemorrhoidal veins.
Colonoscopy
In some cases, especially if you have risk factors for colorectal cancer, symptoms suggest other digestive issues, or you are middle-aged and haven’t had a recent screening, your doctor might recommend a colonoscopy. This procedure examines the entire colon using a longer, flexible tube with a camera.

Treatment Options for Hemorrhoids
Treatment for hemorrhoids depends on the severity of your symptoms. Many cases can be managed with home remedies and over-the-counter treatments. More severe cases may require medical procedures or surgery.
Home Remedies
For mild to moderate hemorrhoid symptoms, home care can often provide relief:
- High-Fiber Diet: Eating plenty of fiber from fruits, vegetables, and whole grains softens stools, making them easier to pass and reducing straining. Gradually increase fiber intake to avoid gas and bloating.
- Topical Treatments: Over-the-counter hemorrhoid creams, ointments, suppositories, and pads containing ingredients like hydrocortisone, witch hazel, or numbing agents can relieve itching, pain, and inflammation.
- Sitz Baths: Soaking the anal area in warm water for 10-15 minutes, two to three times a day, can soothe irritation and promote healing. A sitz bath is a basin that fits over the toilet for convenience.
- Oral Pain Relievers: Over-the-counter pain medications like acetaminophen (Tylenol), ibuprofen (Advil, Motrin), or aspirin can help manage pain and discomfort temporarily.
Medications
If home remedies are insufficient, your doctor may recommend prescription-strength creams, ointments, or suppositories. These may contain higher concentrations of hydrocortisone or other medications to reduce inflammation and pain. However, steroid creams like hydrocortisone should be used for limited periods as they can thin the skin with prolonged use.
External Hemorrhoid Thrombectomy
For painful external hemorrhoids with a blood clot (thrombosed hemorrhoids), a thrombectomy can provide immediate relief. This minor procedure involves surgically removing the clot under local anesthesia. It is most effective if performed within 72 hours of clot formation.
Minimally Invasive Procedures
For persistent bleeding or painful hemorrhoids, several minimally invasive procedures can be performed in a doctor’s office or outpatient setting:
- Rubber Band Ligation: This is a common and effective procedure for internal hemorrhoids. A small rubber band is placed around the base of the hemorrhoid to cut off its blood supply. The hemorrhoid withers and falls off within a week. It can cause mild discomfort and bleeding a few days after the procedure.
- Sclerotherapy: A chemical solution is injected into the hemorrhoid to shrink it. It is less painful than rubber band ligation but might be less effective.
- Coagulation (Infrared, Laser, or Bipolar): These techniques use heat or light to cause small, bleeding internal hemorrhoids to harden and shrivel. They are generally painless with few side effects.
Surgical Procedures
Surgery is usually reserved for severe hemorrhoids that haven’t responded to other treatments.
- Hemorrhoidectomy (Surgical Hemorrhoid Removal): This is the most effective surgical treatment for severe or recurring hemorrhoids. The surgeon removes excess tissue causing bleeding. It can be performed under local, spinal, or general anesthesia. Hemorrhoidectomy is associated with more post-operative pain than other procedures but offers the lowest recurrence rate.
- Stapled Hemorrhoidopexy (Stapled Hemorrhoid Surgery): This procedure is mainly for internal hemorrhoids. A stapling device is used to block blood flow to the hemorrhoidal tissue. It is generally less painful than hemorrhoidectomy with a quicker recovery, but it has a higher risk of hemorrhoid recurrence and rectal prolapse.
Preventing Hemorrhoids
While not always preventable, you can take steps to reduce your risk of developing hemorrhoids:
- Eat a High-Fiber Diet: Include plenty of fruits, vegetables, and whole grains in your diet to prevent constipation.
- Stay Hydrated: Drink plenty of water throughout the day to keep stools soft.
- Avoid Straining: Don’t strain during bowel movements. If you are unable to pass stool easily, try increasing your fiber and fluid intake.
- Go to the Toilet When You Need To: Don’t delay bowel movements, as this can lead to constipation and straining.
- Limit Sitting Time: Avoid prolonged sitting, especially on the toilet. Take breaks and move around if your job requires you to sit for long periods.
- Maintain a Healthy Weight: If you are overweight or obese, losing weight can help reduce pressure on your rectal veins.
- Regular Exercise: Regular physical activity can help prevent constipation and improve bowel regularity.
When to See a Doctor
While many hemorrhoid symptoms can be managed at home, it’s important to see a healthcare provider if you experience:
- Persistent rectal bleeding: Especially if it is significant or you feel lightheaded or dizzy.
- Severe pain: That is not relieved by home remedies.
- Hemorrhoids symptoms that don’t improve after a week of home treatment.
- Changes in bowel habits: Such as changes in stool consistency or frequency, or a feeling of incomplete evacuation.
- Blood in your stool: To rule out other potential causes of bleeding in the digestive tract.
Conclusion
Hemorrhoids are a common condition often caused by increased pressure on the veins in the rectum and anus. Understanding the causes, symptoms, and available treatments is crucial for managing this condition effectively. By adopting a high-fiber diet, staying hydrated, avoiding straining, and seeking medical advice when needed, you can significantly reduce your risk of developing hemorrhoids and alleviate symptoms if they occur. Remember to consult with your healthcare provider for personalized advice and treatment options best suited to your individual needs.
