What do hemorrhoids look like and what are the causes?

Hemorrhoids are a common condition where veins in the rectum or anus become swollen and inflamed. They can be internal, located inside the rectum, or external, under the skin around the anus.

Causes of Hemorrhoids

1. Constipation and Straining: Straining during bowel movements due to constipation is a primary cause of hemorrhoids. The increased pressure can lead to swelling of the veins.
2. Prolonged Sitting: Sitting for long periods, especially on the toilet, can increase pressure on the veins in the anus and rectum.
3. Other Factors: Additional risk factors include a low-fiber diet, obesity, and pregnancy, which can all contribute to the development of hemorrhoids.

Appearance

• External Hemorrhoids: These can appear as lumps or swelling around the anus. They may be itchy or painful, and sometimes cause bleeding.
• Internal Hemorrhoids: These are usually not visible but can cause bleeding during bowel movements.

Understanding these causes can help in preventing and managing hemorrhoids effectively by adopting lifestyle changes such as increasing dietary fiber intake and avoiding prolonged sitting.
