E. coli is a type of bacteria that lives in the intestines of humans and animals. While most strains of E. coli are harmless, some can cause serious infections, leading to bloody diarrhea, abdominal cramps, and in severe cases, kidney failure.

In this article, we will discuss the warning signs of E. coli infection that you should be aware of.

1. Diarrhea

The most common symptom of E. coli infection is diarrhea, which may be watery, bloody, or both. The onset of diarrhea usually occurs within two to five days after exposure to the bacteria, although it can take up to 10 days for symptoms to appear.

The duration of diarrhea can range from a few days to several weeks.

2. Abdominal Pain and Cramps

Abdominal pain and cramps are another common symptom of E. coli infection. The pain may be mild or severe and can occur anywhere in the abdomen. It usually begins a day or two after the onset of diarrhea and can continue for several days.

3. Nausea and Vomiting

Nausea and vomiting are common symptoms of E. coli infection, especially in children. These symptoms may be accompanied by a loss of appetite and a general feeling of malaise.

They typically develop within a few days of exposure to the bacteria and can last for several days.

4. Fatigue

Fatigue is a common symptom of E. coli infection, especially in severe cases. It can be caused by the loss of fluids and electrolytes through diarrhea and vomiting, as well as the body’s response to infection.

Fatigue can persist for several weeks after the other symptoms have resolved.

5. High Fever

In some cases, E. coli infection can cause a high fever, which is usually a sign of a more serious infection. The fever may be accompanied by other symptoms, such as chills and sweating.

It is important to seek medical attention if you develop a fever, especially if it is accompanied by other symptoms.

6. Dehydration

Dehydration is a common complication of E. coli infection, especially in young children, seniors, and people with weakened immune systems. It can occur as a result of the loss of fluids and electrolytes through diarrhea and vomiting.

Signs of dehydration include dry mouth, thirst, dizziness, and decreased urine output.

7. Blood in the Stool

Blood in the stool is a common symptom of E. coli infection, especially in cases of severe infection. The blood may be bright red or dark and may be mixed with mucus or pus. It is important to seek medical attention if you experience blood in your stool.

8. Kidney Failure

In rare cases, E. coli infection can lead to kidney failure, a life-threatening condition that requires immediate medical attention.

Symptoms of kidney failure include decreased urine output, swelling of the legs, ankles, and feet, fatigue, and high blood pressure. If you experience any of these symptoms, seek medical attention right away.

9. Hemolytic Uremic Syndrome (HUS)

Hemolytic uremic syndrome (HUS) is a rare but serious complication of E. coli infection, especially in children under the age of five.

HUS is a type of kidney failure that can result in the destruction of red blood cells, low platelet counts, and damage to the kidneys. Symptoms of HUS include pale skin, fatigue, decreased urine output, and easy bruising or bleeding.

10. Anemia

Anemia is a common complication of E. coli infection, especially in cases of severe infection. It can be caused by the destruction of red blood cells as a result of HUS or other complications.

Symptoms of anemia include fatigue, pale skin, and shortness of breath.

Conclusion

E. coli infection can cause a range of symptoms, from mild diarrhea to life-threatening complications such as kidney failure. If you experience any of the warning signs of E. coli infection, seek medical attention right away.

To reduce your risk of infection, practice good hygiene, cook meat to a safe temperature, and wash all fruits and vegetables before eating.
