Hemorrhoids

Hemorrhoids are swollen and inflamed veins in the lower rectum or anus. They are similar to varicose veins and can develop inside the rectum, called internal hemorrhoids, or under the skin around the anus, called external hemorrhoids. Hemorrhoids are very common and often related to increased pressure in the rectal area.

Many people experience hemorrhoids at some point in their lives, especially during adulthood. They can cause discomfort, pain, itching or bleeding during bowel movements. In many cases, hemorrhoids are mild and improve with simple lifestyle changes, though severe cases may require medical treatment.

Hemorrhoids are not usually dangerous, but symptoms can be bothersome and may interfere with daily activities. Early recognition and proper care can help prevent worsening symptoms and complications.

Symptoms

Symptoms of hemorrhoids depend on whether they are internal or external.

Common symptoms may include:

• Painless bleeding during bowel movements

• Bright red blood on toilet paper or in the toilet bowl

• Itching or irritation in the anal region

• Pain or discomfort, especially with external hemorrhoids

• Swelling or a lump near the anus

• Leakage of stool in severe cases

Internal hemorrhoids usually do not cause pain but may prolapse, meaning they protrude outside the anus. External hemorrhoids can be painful, especially if a blood clot forms, a condition known as thrombosed hemorrhoids.

Causes

Hemorrhoids develop when increased pressure causes veins in the rectal area to stretch and swell. Several factors may contribute to this increased pressure.

Common causes include:

• Straining during bowel movements

• Chronic constipation or diarrhea

• Sitting for long periods, especially on the toilet

• Pregnancy, due to increased pressure on pelvic veins

• Obesity

• Low-fiber diet

• Heavy lifting

Aging can also weaken the tissues that support veins in the rectum and anus, increasing the risk of hemorrhoids.

Risk factors

Factors that increase the risk of developing hemorrhoids include:

• Chronic constipation or frequent straining

• Pregnancy and childbirth

• Prolonged sitting or sedentary lifestyle

• Obesity

• Low intake of dietary fiber

• Advancing age

Complications

Most hemorrhoids do not cause serious problems, but complications can occur in some cases.

Possible complications include:

• Anemia from chronic blood loss

• Thrombosed hemorrhoids causing severe pain and swelling

• Strangulated hemorrhoids when blood supply is cut off

• Infection or ulceration of hemorrhoidal tissue

Prompt treatment can help reduce discomfort and prevent complications.

Prevention

Hemorrhoids can often be prevented by reducing pressure on rectal veins and promoting healthy bowel habits.

Preventive measures include:

• Eating a high-fiber diet with fruits, vegetables and whole grains

• Drinking plenty of fluids

• Avoiding straining during bowel movements

• Not delaying the urge to pass stool

• Exercising regularly to prevent constipation

• Avoiding prolonged sitting, especially on the toilet

Maintaining healthy bowel habits is key to preventing hemorrhoids and reducing the risk of recurrence.
