How to completely treat internal hemorrhoids?
In recent years, there have been numerous treatment methods for internal hemorrhoids, primarily divided into non-surgical and surgical treatments. Non-surgical treatment mainly involves conservative management, which generally includes measures such as increasing the intake of vegetables and fruits, maintaining smooth bowel movements, and using medications or applying ointments locally. Surgical treatment mainly includes injection therapy and excision of the hemorrhoidal nodes. For a complete cure, surgical treatment is typically required, which involves thoroughly removing the pathological hemorrhoidal nodes. (The use of medications should be under the guidance of a doctor.)
Is a severe internal hemorrhoid prolapse?
Internal hemorrhoids mainly refer to soft venous masses that occur above the dentate line, formed by congestion, dilation, and varicosity of the superior rectal venous plexus. The primary symptoms are rectal bleeding and prolapse of the lump outside the anus. Prolapse of internal hemorrhoids is one of the indications for surgery, meaning that if there is rectal bleeding or prolapse outside the anus at the dentate line, surgical treatment is required. Thus, internal hemorrhoids are considered severe if there is a prolapse, necessitating surgical treatment.
Will internal hemorrhoids affect menstruation?
Internal hemorrhoid bleeding can potentially affect menstruation. Although brief internal hemorrhoid bleeding does not affect menstruation, if the hemorrhoid bleeding is heavy, prolonged, frequent, and occurs daily or frequently, exceeding the body's ability to replace the lost blood, it can cause severe systemic anemia. In such cases, it might affect menstruation.
What causes external hemorrhoids to itch?
External hemorrhoids are hypertrophic skin tags at the anal margin and surrounding skin, or dilation of the subcutaneous venous plexus leading to blood stasis and thrombus formation, resulting in protruding lesions. According to their characteristics, they can be divided into connective tissue external hemorrhoids, thrombotic external hemorrhoids, varicose external hemorrhoids, and inflammatory external hemorrhoids. In particular, inflammatory external hemorrhoids can cause the surrounding skin to become moist. This moisture can lead to the formation of eczema and pruritic diseases in the surrounding skin, causing skin lesions. One of the main features after skin lesions is itching around the skin surrounding the external hemorrhoids.
Postoperative Care for Rectal Prolapse Surgery
Post-Rectal Prolapse Surgery Precautions: 1. Rest in bed, which helps improve the recovery rate. Due to gravity, many patients with rectal prolapse experience prolapse when standing or walking. Although the surgery fixes the prolapsed mucosa, the firmness of the fixation takes time to establish. Therefore, it is recommended to rest in bed with limited activity for one week after the surgery to solidify the therapeutic effects. 2. Take oral antibiotics for 7 to 10 days after surgery. 3. Abstain from food for the first two days after surgery, and consume semi-liquid or liquid foods in reduced quantities on the third day. 4. Refrain from defecating for 4 to 5 days after surgery. 5. Do not strain during the first bowel movement after surgery. (Please use medications under the guidance of a professional physician)
Internal hemorrhoids bleeding is what color?
Rectal bleeding is the primary clinical symptom of internal hemorrhoids, typically characterized by bright red blood. Bleeding after bowel movements is one of the early symptoms of internal hemorrhoids, which often have no significant initial conscious symptoms, commonly presenting as blood-streaked stool after defecation. Bleeding after bowel movements can appear as dripping or spraying, bright red, painless, and not mixed with the stool. This distinction is crucial for differentiating from cancer. Rectal bleeding generally increases in severity over time, progressing from small amounts of blood to significant bleeding. Prolonged and repeated bleeding can lead to severe anemia in patients.
Can a twenty-year anal fistula turn into cancer?
Firstly, anal fistulas can become cancerous. Statistical data show that the probability of malignant transformation in anal fistulas is 1/1000, and such transformations are relatively rare in clinical practice. However, anal fistulas can change, but the timing of malignant transformation varies. Generally, the longer the duration of an anal fistula, the higher the chance of it becoming cancerous. The factors contributing to this transformation typically include chronic inflammation, long-term irritation, bacterial infection, and stimulation from medications, all of which can lead to cancerous changes.
Can excessive bleeding from internal hemorrhoids cause dizziness?
Excessive bleeding from internal hemorrhoids can lead to symptoms of dizziness. Bleeding is one of the main clinical manifestations of internal hemorrhoids. The amount of bleeding can vary, and the color of the blood is typically bright red. If there is a large amount of bleeding, lasts for a long time, or occurs frequently, and it exceeds the body's ability to produce new blood, it can lead to systemic anemia. Prolonged conditions can result in severe anemia, which may cause dizziness.
The main causes of anal fissures
The main causes of anal fissure formation may be related to the following factors: long-term constipation and hard stools, which cause mechanical damage during defecation as the direct cause for most anal fissures. It is also related to anatomical defects. Due to the superficial layer of the external sphincter forming a weak area at the back of the anal canal, dry stools exert the greatest pressure on the weak area at the back of the anus, making it prone to tearing injuries. Additionally, infection of the anal sinuses can lead to inflammation of the anal canal, and spasms of the sphincter losing its soft characteristics is also a reason for the formation of anal fissures. Furthermore, hard and dry fecal masses passing through the anal canal can easily cause tearing injuries, possibly due to the smaller size of the patient's anus.
Characteristics of anal fissure with bleeding
An anal fissure is a small ulcer formed by the full-thickness splitting of the skin of the anal canal below the dentate line. A characteristic of bleeding due to an anal fissure is that it generally occurs along with periodic, tearing-like pain. Thus, bleeding and pain are the main clinical manifestations of an anal fissure. During defecation, the damaged surface can lead to bleeding from the fissure, usually with a small amount of blood. The stool may have streaks of blood, or there might be a few drops of fresh blood after defecation, or a slight smearing of fresh blood on toilet paper during wiping.
