Hemorrhoids, also known as piles, are swollen and inflamed veins in the lower rectum and anus, similar to varicose veins. They can cause pain, itching, and bleeding, especially during bowel movements. Increased pressure in these veins, often due to straining during bowel movements or chronic constipation, weakens the vein walls and causes inflammation.
Symptoms of hemorrhoids
The symptoms of hemorrhoids can vary depending on their type and severity. Some patients may be asymptomatic, while others experience significant discomfort. Common symptoms include:
Painless bleeding during defecation:
this is often the first and most common symptom. The blood is usually bright red and can be seen on toilet paper, in stool, or in the toilet bowl.
Itching or irritation in the anal area:
inflammation of the veins can cause itching and irritation around the anus.
Pain or discomfort:
pain can be mild or severe, especially when sitting or during defecation.
Swelling around the anus:
Swelling around the anus:
hemorrhoids can cause visible swelling around the anus.
Palpable bulge near the anus:
in some cases, a bump or lump may be felt near the anus, which may be painful to the touch.
It is important to remember that the severity and presentation of symptoms can vary from person to person.
Classification of hemorrhoids
Hemorrhoids are classified into two main types:
Internal hemorrhoids: they are located inside the rectum and are generally not visible or palpable. They are classified into four grades according to their prolapse (descent from their normal location):
Grade I: they do not protrude from the anus.
Grade II: they protrude during defecation, but retract spontaneously.
Grade III: they protrude during defecation and require manual pushing back in.
Grade IV: they prolapse permanently and cannot be pushed back in.
External hemorrhoids: they are located beneath the skin around the anus and are visible and palpable. They can cause severe pain if a blood clot (thrombosis) forms.
Causes of hemorrhoids
Although the exact cause of hemorrhoids is not always known, several factors can contribute to their development:
Straining during bowel movements: excessive straining during defecation increases the pressure in the veins of the rectum and anus.
Constipation: hard, dry stools make defecation difficult, leading to greater straining.
Diarrhea: prolonged diarrhea can irritate and inflame the anal veins.
Pregnancy: increased pressure in the abdomen during pregnancy can affect blood flow in the veins of the rectum and anus.
Obesity: excess weight can increase the pressure in the veins of the rectum and anus.
Genetics: some people may have a genetic predisposition to developing hemorrhoids.
Low-fiber diet: a low-fiber diet can cause constipation.
Aging: the supporting tissues of the veins weaken with age.
Spending a long time sitting on the toilet: this can increase pressure in the veins of the rectum and anus.
Although complications from hemorrhoids are rare, they can include:
Anemia: chronic bleeding can cause iron deficiency anemia.
Strangulation of a hemorrhoid: if the blood supply to an internal hemorrhoid is cut off, it can cause severe pain and tissue necrosis.
Hemorrhoidal thrombosis: the formation of a blood clot in an external hemorrhoid can cause severe pain and a hard, painful lump near the anus.
It is essential to seek medical advice if any of these complications are suspected.
Diagnosis of hemorrhoids
An accurate and timely diagnosis is essential to determine the most appropriate treatment for hemorrhoids. Hemorrhoids are usually diagnosed through a physical examination. The diagnostic process generally involves the following steps:
Medical history: the doctor will ask about symptoms, medical history, and lifestyle. It is important to be honest and detailed when describing your symptoms, including the frequency, duration, and any other triggers.
Physical examination:
Visual inspection: the doctor examines the anal area to detect external hemorrhoids, fissures, fistulas, or other abnormalities.
Digital rectal examination: the doctor inserts a gloved and lubricated finger into the rectum to palpate for internal hemorrhoids, assess anal sphincter tone, and detect masses or areas of tenderness. Although it may be uncomfortable, it is an important part of the exam.
Additional diagnostic tests: depending on your symptoms and the findings of the physical exam, the doctor may recommend additional tests, such as:
Anoscopy: an anoscope, a short tube with a light, is used to visualize the anal canal. It allows the doctor to observe the internal hemorrhoids and assess their severity.
Proctoscopy: a proctoscope, a longer, more flexible tube, is used to visualize the rectum. This test may be necessary to rule out other conditions, such as polyps or colorectal cancer.
Sigmoidoscopy: in some cases, a sigmoidoscopy may be performed to examine the lower part of the colon.
At HM Hospitales, we have specialized digestive disease units staffed by highly qualified professionals and equipped with advanced technology for accurate diagnosis. https://www.hmhospitales.com/especialidad/gastroenterologia-aparato-digestivo/The Proctology Unit offers a multidisciplinary approach, combining medical expertise with the most advanced technology to provide an accurate diagnosis and a personalized treatment plan. In addition to the diagnostic tests mentioned above, the unit can perform more specific tests, such as anorectal manometry and endorectal ultrasound, to assess the function of the anal sphincter muscles and the surrounding structures. This comprehensive approach allows for a more accurate diagnosis and more effective treatment of hemorrhoids and other proctological conditions.
Hemorrhoid treatments
The treatment of hemorrhoids depends on the severity of the symptoms and the type of hemorrhoids. Treatment options include:
Non-pharmacological treatments:
Sitz baths: soaking the anal area in warm water for 10–15 minutes several times a day can relieve itching and pain.
Increase fiber in the diet: following a diet rich in fiber (fruits, vegetables, whole grains) helps soften stools and facilitates defecation, reducing straining.
Stool softeners: these medications help soften stools and facilitate defecation.
Lifestyle changes: avoiding spending too much time sitting on the toilet and maintaining a healthy weight can help prevent hemorrhoids.
Pharmacological treatments:
Topical creams and ointments: creams and ointments containing corticosteroids, local anesthetics, or protectants can relieve itching, pain, and inflammation.
Minimally invasive procedures:
Elastic band ligation: a small elastic band is placed around the base of the internal hemorrhoid, cutting off its blood supply and causing it to shrink and fall off.
Sclerotherapy: a chemical solution is injected into the hemorrhoid, causing it to shrink.
Infrared coagulation: infrared heat is used to coagulate the hemorrhoid.
Surgery:
Hemorrhoidectomy: it is a surgical procedure to remove hemorrhoids. It is reserved for severe cases or when other treatments have not been effective.
Hemorrhoidal stapling: a circular stapler is used to remove the internal hemorrhoidal tissue and reposition the prolapsed tissue.
