hemorrhoids symptoms,Symptoms of hemorrhoids

    Symptoms of hemorrhoids

    The main symptoms of internal hemorrhoids are blood in the stool. Larger internal hemorrhoids are accompanied by prolapse. Due to the length of the disease, it can be divided into the following stages.

    Early stage: The hemorrhoids are small, soft, and bright red on the surface of the hemorrhoids. They often bleed due to the hemorrhoids being rubbed by the stool. The blood is either a thread like an arrow or dripping, no pain, no prolapse, so that the blood is characteristic.

    Intermediate stage: The hemorrhoids are large and swollen and soft in texture. The surface of the hemorrhoids is bright red or bluish purple. The hemorrhoids protrude out of the anus during the defecation, and will be absorbed by themselves after the defecation, with more or less bleeding after defecation.

    Late stage: The hemorrhoids are larger, harder, and slightly off-white on the surface (ie, fibrous internal hemorrhoids). The hemorrhoids prolapse outside the anus during the defecation, even when walking, coughing, sneezing, or standing. They cannot be picked up on their own. Push it back, or lie on your back, and apply heat to it. There is not much blood in the stool or no more bleeding.

    Complications: In the middle and late stages, anal swelling and itching may occur. Such as acute thrombotic incarceration of hemorrhoids, it can cause swelling, pain, erosion, necrosis, even suppuration, and secondary anal leakage. Long-term blood in the stool can cause anemia.

    External hemorrhoids occur below the tooth line of the anal canal. They are caused by enlarged varicose or repeated inflammation of the external hemorrhoid venous plexus. Its surface is covered by skin and is not easy to bleed. Its shape and size are irregular.

    The main symptoms of external hemorrhoids are swelling, pain, and foreign body sensation. According to its development process, it can be divided into epidermal external hemorrhoids, venous external hemorrhoids and thrombotic external hemorrhoids.

    Epidermal external hemorrhoids: The neoplastic flap at the edge of the anus, gradually enlarged, is soft in texture, generally painless, does not bleed, only feels foreign body sensation in the anus, and occasionally feels pain when swelling and congestion due to poisoning. After the swelling disappears, The epidermis still exists.

    Venous external hemorrhoids: mostly due to repeated prolapse of internal hemorrhoids in the middle and late stages, or due to increased abdominal pressure during pregnancy, which results in the obstruction of superficial veins and subcutaneous lymphatic drainage, causing the expansion and varicose of the external hemorrhoidal venous plexus below the anal canal tooth line to make. Its clinical manifestations: local oval or long tumors, which are soft to the touch and not obvious in normal times. When the abdominal pressure is increased during defecation or squatting, the volume of the tumor increases and appears dark purple, and it is harder. The volume of the mass can be reduced and softened after massage. Generally, there is only a feeling of swelling without pain. If the mass does not shrink after going to the toilet, it will cause pain when the surrounding tissues are edema. Patients with venous external hemorrhoids often have internal hemorrhoids.

    Thrombotic external hemorrhoids: Excessive force during defecation due to constipation, or after strenuous exercise, causes the external hemorrhoid veins to rupture and blood clots quickly to form thrombus. Its clinical manifestations: sudden severe pain in the anus, and a swelling appears. This swelling is very sensitive and can cause pain when touched. Therefore, the pain can be aggravated during defecation, sitting, walking, and even coughing.

    Mixed hemorrhoids: it is a varicose plexus of internal hemorrhoids and external hemorrhoids, which communicate and anastomoses with each other, and the groove between the sphincter disappears, and the internal hemorrhoids and the external hemorrhoids form a whole. It has the common characteristics of internal and external hemorrhoids.
