What are the symptoms of bacillary dysentery?

Bacillary dysentery is a relatively rare infectious disease. This disease has a great impact on people's bodies. It can cause serious infections and lead to problems such as organ failure, which seriously threatens people's lives and safety. Therefore, when encountering this disease, you must be vigilant and seek medical attention in time. Let’s take a look at what the symptoms of bacillary dysentery are like. I hope everyone can understand.

Bacillary dysentery, also known as shigellosis, is an intestinal infectious disease caused by Shigella (Shigella dysenteriae).

The main symptoms are systemic poisoning and gastrointestinal symptoms, which can be divided into four types: (1) Common type (typical): The onset is acute, with moderate toxemia, chills, fever up to 39°C, fatigue, loss of appetite, nausea, vomiting, abdominal pain, diarrhea, and tenesmus. The patient first has watery stools, which turn into bloody stools after 1 to 2 days. The patient has dozens of bowel movements a day, with small amounts of stool and no significant water loss. It is often accompanied by hyperactive bowel sounds and left lower abdominal tenderness. The general course of the disease is 10 to 14 days. (2) Mild (atypical) Symptoms of systemic poisoning, abdominal pain, tenesmus, and tenderness in the left lower abdomen are not obvious. There may be low fever, mushy or watery stools mixed with a small amount of mucus, and no pus or blood. The number of diarrhea episodes is generally less than 10 times a day. Microscopic examination of stool shows red and white blood cells, and culture shows the growth of Shigella dysenteriae, which can be used to distinguish it from acute enteritis. The general course of the disease is 3 to 6 days.

(3) Severe cases are more common in elderly, weak or malnourished patients. There are severe systemic poisoning symptoms and intestinal symptoms. The disease has an acute onset, high fever, nausea, vomiting, severe abdominal pain and tenderness in the abdomen (especially in the left lower abdomen), obvious tenesmus, bloody stools, frequent bowel movements, and even incontinence. The disease progresses rapidly, with obvious water loss, cold limbs, extreme exhaustion, and easy occurrence of shock. (4) Toxic type: This type is more common in children aged 2 to 7 years old with good physical constitution. The onset is acute, with obvious symptoms of systemic poisoning, high fever reaching over 40°C, patients with lethargy, pale complexion, cold limbs, weak breathing, skin patterns, repeated convulsions, drowsiness, and even coma, while the intestinal inflammatory reaction is extremely mild. According to clinical manifestations, it can be divided into shock type (with infectious shock as the main manifestation), brain type (with central nervous system symptoms as the main manifestation) and mixed type (with manifestations of both types, which is the most dangerous). This is due to the action of Shigella dysenteriae endotoxin and may be related to the specific constitution of some children.
