• People who have had a recent bout of food poisoning: Testing for E. coli can help to determine the cause of the food poisoning and identify any underlying health conditions that may have contributed to it.
• People with chronic digestive problems: E. coli levels can be disrupted in people with conditions such as irritable bowel syndrome (IBS), Crohn’s disease, and ulcerative colitis. Testing can help to identify any imbalances that may be contributing to their symptoms.
• People who are at risk of getting E. coli infection: This includes people who work with food, travel to developing countries, or have weakened immune systems. Testing can help to identify people who may be more susceptible to infection and allow them to take preventative measures.

In general, low levels of E. coli are not a cause for concern. However, in some cases, low levels of E. coli can be associated with conditions such as:

• Irritable bowel syndrome (IBS)
• Stomach ulcers
• Inflammatory bowel disease (IBD)

Too high levels of E. coli can be a sign of food poisoning. Symptoms of food poisoning caused by E. coli can include:

• Diarrhea
• Vomiting
• Abdominal cramps
• Fever
• Bloody stool

In severe cases, E. coli infection can lead to kidney failure, hemolytic uremic syndrome (HUS), and even death.

E. coli is a beneficial bacteria that helps to keep the gut healthy. It helps to break down food, produce vitamins, and regulate the immune system. E. coli also helps to prevent the growth of harmful bacteria in the gut.

Yes, E. coli can cause lasting problems in some people. The most common lasting problem is irritable bowel syndrome (IBS). It is thought that E. coli infection can damage the lining of the gut, which can lead to IBS.

Other lasting problems that can be caused by E. coli infection include:

• Crohn’s disease, an inflammatory bowel disease that causes inflammation of the digestive tract
• Ulcerative colitis, another inflammatory bowel disease that causes inflammation of the large intestine
• Renal failure, a condition in which the kidneys fail to function properly
• Hemolytic uremic syndrome (HUS), a condition that can cause kidney failure, seizures, and even death

The risk of developing lasting problems from E. coli infection is higher in people with weakened immune systems, such as the elderly, young children, and people with chronic health conditions.
