Can hemorrhoids cause swelling around the anus?

Hemorrhoids can cause swelling around the anus, which is usually caused by abnormal dilation of local blood vessels or inflammatory reactions caused by hemorrhoids. Specific manifestations may include mild swelling and tenderness. In severe cases, it may cause obvious discomfort and even affect bowel movements.

Swelling around the anus is mainly related to the type and severity of hemorrhoids: internal hemorrhoids may cause swelling inside the anus due to the expansion of the submucosal venous plexus; external hemorrhoids usually appear as obvious bulges under the skin. Mixed hemorrhoids affect both the internal and external anal areas, aggravating the local swelling. The causes of hemorrhoids include genetics, such as the fragility of the family's venous system; environmental factors, such as long periods of sitting or standing, spicy food, and physiological factors, such as constipation or increased abdominal pressure during pregnancy, which leads to compression of the rectal veins. In addition, long-term blood in the stool may also cause inflammation, further aggravating swelling.

The key to intervention for swelling around the anus is to relieve inflammation and improve venous return. In terms of drug treatment, you can use local anti-inflammatory ointments, such as hemorrhoid suppositories and compound carraghenate cream; oral drugs to relieve venous congestion, such as diosmin tablets; if the swelling is severe, the doctor may recommend sclerotherapy injection or external hemorrhoidectomy. Lifestyle adjustments are also important. It is recommended to consume more foods rich in dietary fiber, such as oats and green leafy vegetables, and avoid spicy stimulation; maintain daily moderate exercise such as brisk walking to promote blood circulation. You also need to pay attention to anal hygiene and use warm water sitz baths to relieve discomfort.

Anal swelling may be caused by other factors, such as perianal abscesses or skin lesions. It is recommended to seek medical attention as soon as possible if the symptoms persist or worsen and receive treatment based on professional advice. There is no need to worry about hemorrhoids. Through scientific treatment and conditioning, most patients can effectively improve and resume a healthy life.
