Prognosis is a medical term that predicts the likely course disease can take and how will the symptoms change as the disease progresses. In most cases of dysentery, symptoms will resolve on their own within a duration of 3-7 days without any intervention. However, medical treatment is needed if the symptoms are severe or to get better quickly. In some cases, dysentery can lead to complications, which differ according to the causative agent. Possible complications for both types of dysentery have been discussed below.
1) Shigella Dysentery
Shigella sonnei is the most common species globally, including in developed countries, while Shigella flexneri is more common in the developing countries of Asia and Africa. Shigella dysenteriae can cause more serious illness for long periods of time because it produces a potent enterotoxin which can cause hemolytic-uraemic syndrome which can be fatal. Shigella dysentery can also lead to complications like rectal prolapse, perforation of the intestine, toxic megacolon, seizures, sepsis, etc.
