There are several disorders to consider in postpartum anal distension: first, hemorrhoids, which is the most common disorder in anorectal medicine. This symptom may occur due to the aggravation of hemorrhoids due to dietary restrictions and limited activity during pregnancy and during the postpartum period, often accompanied by symptoms such as blood in the stool. Next, consider perianorectal abscess, which is a possible condition if accompanied by fever and diarrhea. Also, consider the possibility of sinusitis, which is often accompanied by burning, swelling and pain in the anus. In addition, there will be discharge, dampness, and itching at the anal opening. Regardless of the cause, the first thing to do is to keep the anal area clean, try to eat a light diet, and then go to a specialized hospital for examination if convenient.
