Verenvuodoissa

Verenvuodoissa, also known as hemorrhoids, are swollen veins in the lowest part of the rectum and anus, with or without the presence of external prolapse. They are a common condition that affects many people, particularly those over the age of 50. Hemorrhoids can be classified into two main types: internal and external.

Internal hemorrhoids occur inside the rectum and are not visible or palpable. They are more common and usually do not cause symptoms. External hemorrhoids, on the other hand, are visible as swollen veins outside the anus. They can be painful and may cause bleeding, itching, or a sensation of something prolapsing from the anus.

The exact cause of hemorrhoids is not fully understood, but they are often associated with increased intra-abdominal pressure, such as during straining during bowel movements, heavy lifting, or prolonged standing. Other risk factors include a low-fiber diet, obesity, and pregnancy.

Symptoms of hemorrhoids can range from mild to severe and may include pain, itching, bleeding, and a sensation of something prolapsing from the anus. In some cases, hemorrhoids can lead to complications such as anal fissures, fistulas, or abscesses.

Treatment for hemorrhoids typically involves lifestyle changes, such as increasing fiber intake, maintaining a healthy weight, and avoiding prolonged sitting or standing. Over-the-counter creams and ointments may also be used to relieve symptoms. In more severe cases, medical intervention may be necessary, such as rubber band ligation, sclerotherapy, or surgery.
