Hemorrhoids are not cancer; they are a benign and common local disease of the anus. The main cause is due to the displacement of the anal cushion or the formation of varicose veins and thrombi in the local mucosal tissue, leading to protrusion, swelling, and even pain and bleeding of the local mucosa. Hemorrhoids are a common proctological disease, with an incidence rate of about 60% among adults, primarily influenced by poor dietary and defecation habits. Therefore, to prevent the onset of hemorrhoids, it is recommended to avoid overly spicy and irritating foods and to keep bowel movements under ten minutes to prevent overly dry stools.

Do hemorrhoids bleed and hurt?

Simple hemorrhoids bleeding generally has no pain symptoms. Pain only occurs when the hemorrhoids are inflamed or when there is prolapsed or thrombosed external hemorrhoids. Hemorrhoids are caused by the tortuous dilation of hemorrhoidal venous plexus. Some patients have symptoms of hemorrhoidal prolapse, some have rectal bleeding with fresh blood that is separate from the stool, and a few have both prolapse and bleeding. If the prolapse of hemorrhoids is severe, or if there is a significant amount of bleeding, surgical treatment is recommended. If the bleeding is minor and the hemorrhoids are not severe, conservative treatment can be implemented, including topical medication and maintaining smooth bowel movements. It is advised to avoid alcohol, spicy and irritating foods, and to keep the perianal area clean and hygienic.

What are the symptoms of hemorrhoids in pregnant women?

After pregnancy, the volume of the female uterus increases, and in late pregnancy, the fetus descends into the pelvis. These factors can compress the veins in the pelvic area, obstructing blood flow around the anus, causing venous blood stagnation around the anus, and making it easy for pregnant women to develop hemorrhoids or for pre-existing hemorrhoids to worsen during pregnancy. The symptoms of hemorrhoids in pregnant women include the following aspects: first, you can feel polyp-like tissue outside the anus with your hand. Second, when hemorrhoids are severe, they can cause the prolapse of hemorrhoidal tissue or be accompanied by anal bleeding. Third, hemorrhoids can sometimes be accompanied by constipation, and hemorrhoids during pregnancy should be treated through diet, exercise, and medication.

Internal hemorrhoids can cause rectal bleeding, typically occurring during defecation, ranging from dripping to jet-like bleeding. Rectal bleeding is painless, and prolonged bleeding can lead to anemia characterized by loss of appetite, fatigue, and lack of concentration. It is important to timely apply hemostatic medications or opt for treatments like electrocoagulation, banding, or surgery. Dietary adjustments should be made by increasing the intake of vegetables and fruits and reducing spicy, greasy, and irritating foods. Regular routines should be maintained, avoiding prolonged sitting, and using warm water for sitz baths every evening can effectively relieve the symptoms of hemorrhoidal venous dilatation.

How to treat hemorrhoids with bleeding?

If the bleeding from hemorrhoids is not severe, treatment might not be necessary for the time being. However, it is important to be cautious in daily life. Avoid consuming spicy, cold, or greasy foods, and ensure that bowel movements are smooth to prevent constipation and diarrhea. Doing so will gradually reduce the bleeding and improve the condition. If the condition worsens and the bleeding increases, topical ointments can be applied as a treatment. Additionally, taking oral hemostatic medications and employing sitz baths as treatment methods can be beneficial. If bleeding persists repeatedly and does not improve after these treatments, or if the bleeding is substantial, surgery might be required.

Hemorrhoids with bloody stools belong to what type of hemorrhoids?

Hemorrhoids are divided into internal and external hemorrhoids. Bleeding from hemorrhoids generally belongs to internal hemorrhoids or develops into mixed hemorrhoids. Therefore, hemorrhoidal bleeding is due to internal hemorrhoids or mixed hemorrhoids. Hemorrhoids are classified into four degrees: First-degree hemorrhoids do not prolapse. Second-degree hemorrhoids prolapse during defecation when abdominal pressure increases but can retract spontaneously afterward. Third-degree hemorrhoids involve prolapse of the hemorrhoidal tissue that requires manual replacement. Fourth-degree hemorrhoids are incarcerated and cannot be retracted. The treatment of hemorrhoidal bleeding depends on the amount and nature of the bleeding. If it is a small amount of bleeding, conservative treatment is generally sufficient, and the bleeding symptoms will disappear. If the bleeding is significant and persistent, failure to promptly address and surgically treat it may lead to chronic anemia and iron deficiency anemia.
