Introduction
Symptoms of E. coli infection generally include diarrhea, frequent urination, fever, abdominal pain, and vomiting. E. coli primarily resides in the intestines and can promote vitamin synthesis in the human body. However, E. coli is pathogenic; when the body's immunity decreases and fails to suppress the bacteria, it may multiply excessively, invade the intestinal mucosa, and cause abnormal intestinal motility.
The symptoms of E. coli infection generally include diarrhea, frequent urination, fever, abdominal pain, vomiting, etc. The details are as follows:
1. Diarrhea
E. coli primarily resides in the intestines and can promote vitamin synthesis in the body. However, it is also pathogenic. When the body's immunity declines and fails to suppress E. coli, the bacteria may multiply excessively, invade the intestinal mucosa, and cause abnormal intestinal motility, leading to diarrhea.
2. Frequent Urination
If the condition is not promptly controlled, E. coli may travel retrograde into the urinary system, triggering a local inflammatory response. This causes abnormal stimulation of the bladder, resulting in irregular contractions and possibly frequent urination.
3. Fever
If E. coli spreads via the bloodstream to other parts of the body, it activates the immune system, causing an increase in white blood cell count. Influenced by the bacteria, the body's temperature regulation center becomes disrupted, leading to fever.
4. Abdominal Pain
Once E. coli enters the intestines, it may trigger an inflammatory response in the intestinal mucosa. This inflammation stimulates nerve endings in the intestine, causing abdominal pain.
5. Vomiting
After E. coli infection induces intestinal inflammation, it may disrupt the body's fluid and electrolyte balance, resulting in vomiting.
Patients are advised to take medications such as ibuprofen tablets, norfloxacin capsules, and cefuroxime axetil tablets under medical guidance. Additionally, increasing fluid intake and maintaining a light diet are recommended.
