Escherichia coli (E. coli) infections can cause a range of symptoms, which can vary depending on the severity of the infection. In some cases, people may not experience any symptoms at all, while in others, the infection can be life-threatening. Common signs and symptoms of E. coli infection include:
- Diarrhea: This is the most common symptom of E. coli infection. It can range from mild to severe and may be bloody.
- Abdominal pain and cramping: E. coli infection can cause severe abdominal pain and cramping.
- Nausea and vomiting: E. coli infection can cause nausea and vomiting, especially in the early stages of the infection.
- Fatigue: E. coli infection can cause fatigue and weakness, especially in cases where there is significant diarrhea.
- Fever: E. coli infection can cause fever, which may indicate that the infection is spreading or becoming more severe.
In more severe cases, E. coli infection can lead to complications such as hemolytic uremic syndrome (HUS), which is a type of kidney failure. Symptoms of HUS may include decreased urination, fatigue, and swelling of the face, hands, feet, or entire body.
If you are experiencing any of these symptoms, especially if they are severe, you should seek medical attention right away. Early treatment can help prevent the infection from becoming more severe and potentially life-threatening.
