儿童不宁腿综合征：家长和孩子需要了解的知识
This guide explains what hemorrhoids are, common symptoms, risk factors, and evidence-based treatments to help you manage discomfort and prevent flare-ups.
Hemorrhoids are swollen veins in the rectum or anus that cause discomfort, bleeding, or itching. Most cases improve with at-home care and lifestyle changes, while severe cases may need medical procedures. Preventing constipation and avoiding straining during bowel movements are key to reducing flare-ups.
Overview
Hemorrhoids (also called piles) are swollen, inflamed veins in the lower rectum or anus. They are extremely common, affecting about 1 in 2 people at some point in their lives, and range from mild, temporary irritations to severe, painful growths. While hemorrhoids can be uncomfortable, most cases improve with at-home care and lifestyle changes, and severe cases have effective treatment options.
Signs & Symptoms
Symptoms of hemorrhoids vary depending on whether they are internal (inside the rectum) or external (under the skin around the anus). Common signs include: Bright red blood on toilet paper, in the toilet bowl, or on stool after a bowel movement; Itching, irritation, or swelling around the anus; Pain or discomfort, especially with external hemorrhoids or during bowel movements; A soft lump near the anus (for external hemorrhoids); Leakage of stool from the anus (in severe cases).
Bright red blood during bowel movements is a common hemorrhoid symptom, but it can also signal more serious conditions like colorectal cancer, anal fissures, or inflammatory bowel disease. Always tell your doctor about any rectal bleeding to get an accurate diagnosis.
Causes & Risk Factors
Hemorrhoids develop when pressure builds up in the lower rectum, causing veins to stretch and swell. Common causes include straining during bowel movements, chronic constipation or diarrhea, sitting on the toilet for long periods, pregnancy (due to pressure from the growing uterus), obesity, and a low-fiber diet. As you age, the tissues supporting the veins in your rectum and anus naturally weaken, increasing your risk of hemorrhoids.
- Chronic constipation or diarrhea
- Straining during bowel movements
- Sitting on the toilet for prolonged periods (e.g., while scrolling on your phone)
- Pregnancy
- Obesity
- Low-fiber diet
- Aging (vein-supporting tissues weaken over time)
- Frequent heavy lifting that strains abdominal muscles
Diagnosis
To diagnose hemorrhoids, your doctor will first ask about your symptoms and medical history, then perform a physical exam. This usually includes a visual exam of the anus and a digital rectal exam, where the doctor inserts a gloved, lubricated finger into the rectum to feel for abnormal growths. For internal hemorrhoids, they may use an anoscopy (a small tool to look inside the rectum) or recommend a colonoscopy if there is rectal bleeding, to rule out other conditions like colorectal cancer.
Treatment & Management
Most mild to moderate hemorrhoids improve with at-home care and lifestyle changes. Medical procedures are used for severe or persistent cases that do not respond to conservative treatment.
| Severity | Treatment Options |
|---|---|
| Mild (Grade 1-2) | At-home care: Fiber supplements, sitz baths, over-the-counter hemorrhoid creams/ointments, acetaminophen or ibuprofen for pain, avoiding straining and prolonged sitting |
| Moderate (Grade 2-3) | Office-based procedures: Rubber band ligation (tying off the base of the hemorrhoid to cut off blood flow), sclerotherapy (injecting a solution to shrink the hemorrhoid), infrared coagulation (using heat to shrink the tissue) |
| Severe (Grade 3-4) | Surgical options: Hemorrhoidectomy (surgical removal of large hemorrhoids), stapled hemorrhoidopexy (repositioning and stapling hemorrhoid tissue), Doppler-guided artery ligation (tying off blood vessels supplying the hemorrhoid) |
Living With It
Long-term management of hemorrhoids focuses on preventing flare-ups by reducing pressure on rectal veins. Key habits include eating a high-fiber diet, staying hydrated, exercising regularly, and practicing healthy bowel habits. Most people can manage mild hemorrhoids at home and only need medical care for severe or persistent symptoms.
Prolonged sitting on the toilet (even while scrolling on your phone or reading) increases pressure on rectal veins and can worsen existing hemorrhoids or trigger new flare-ups. Try to limit toilet time to 5 minutes or less, and only go when you feel a strong urge to have a bowel movement.

Recovery & management timeline
1-7
Acute Flare-Up
Use over-the-counter pain relievers (acetaminophen or ibuprofen) as needed, apply witch hazel pads or hydrocortisone cream to reduce itching and swelling, take sitz baths 2-3 times a day for 10-15 minutes, increase fiber and water intake to soften stools, and avoid straining during bowel movements.
8-14
Symptom Improvement
Continue eating a high-fiber diet and drinking plenty of water, reduce sitz bath frequency as discomfort eases, avoid prolonged sitting and heavy lifting, and monitor for persistent or heavy bleeding.
Ongoing
Long-Term Maintenance
Maintain 25-30g of daily fiber intake, exercise regularly for 30 minutes most days, practice healthy bowel habits (go when you feel the urge, don't strain), and schedule a follow-up with your doctor if symptoms recur or do not improve with at-home care.
Self-care steps
1Increase your daily fiber intake
Aim for 25-30 grams of fiber daily from foods like berries, broccoli, oats, beans, and whole-grain bread, or take a fiber supplement (such as psyllium) to soften stools and reduce straining during bowel movements.
2Stay hydrated
Drink 6-8 8-ounce glasses of water daily to help fiber work effectively and prevent hard, dry stools that irritate hemorrhoids. Limit caffeine and alcohol, which can dehydrate you and worsen constipation.
3Practice healthy bathroom habits
Go to the bathroom as soon as you feel the urge to have a bowel movement, avoid straining, and limit toilet time to 5 minutes or less to reduce pressure on rectal veins. Do not sit on the toilet for long periods while reading or using your phone.
4Use sitz baths for symptom relief
Sit in a few inches of warm water for 10-15 minutes 2-3 times a day, especially after bowel movements, to relieve itching, pain, and irritation around the anus. You can add Epsom salts to the water for extra relief, but avoid harsh soaps or bubble bath that can irritate the area.
5Avoid activities that increase rectal pressure
Limit prolonged sitting, avoid heavy lifting that strains your abdominal muscles, and wear loose, breathable cotton underwear to reduce irritation around the anus. If you sit for long periods for work, take short breaks to stand and walk every hour.
When to seek medical help
Seek urgent medical care if you experience heavy rectal bleeding (soaking through a sanitary pad or passing large amounts of bright red blood), severe anal pain that does not improve with over-the-counter pain relievers, a lump near the anus that becomes extremely hard, swollen, and painful (a sign of a thrombosed hemorrhoid), or symptoms accompanied by fever, dizziness, or fainting. Schedule a routine doctor's appointment if you have rectal bleeding that lasts more than 2-3 days, if your symptoms do not improve after 1 week of consistent at-home care, or if you have frequent hemorrhoid flare-ups.
