What are the symptoms of e coli?

The symptoms of E. coli infection can vary depending on the strain of bacteria involved. Some common symptoms may include:

1. Diarrhea: Watery, loose stools are a common symptom of E. coli infection. In severe cases, the diarrhea may be bloody.

2. Abdominal pain and cramps: E. coli infection can cause severe abdominal pain and cramps.

3. Nausea and vomiting: Some people with E. coli infection may experience nausea and vomiting.

4. Fever: In some cases, an E. coli infection can cause a fever.

5. Fatigue and weakness: A person with E. coli infection may experience fatigue and weakness.

6. Loss of appetite: An E. coli infection can lead to loss of appetite.

7. Dehydration: Severe diarrhea and vomiting can lead to dehydration, which can cause dizziness, lightheadedness, and decreased urine output.

8. Bloody stools: In severe cases, the diarrhea associated with E. coli infection can be bloody.

9. Kidney failure: Some strains of E. coli, such as Shiga toxin-producing E. coli (STEC), can cause a serious complication called hemolytic uremic syndrome (HUS). HUS can lead to kidney failure, which can cause decreased urine output, fluid retention, and high blood pressure.

It's important to seek medical attention promptly if you're experiencing symptoms of E. coli infection, especially if you have bloody stools, severe abdominal pain, high fever, or signs of dehydration.
