How long do intestinal infections last?

A reader suffering from an intestinal infection, prone to diarrhea and requiring a restrictive diet, asks about the duration of the infection and the possibility of complete recovery. (Ha, Ho Chi Minh City)

Response:

The recovery time for an intestinal infection depends on several factors, with the causative agent being the most crucial. Generally, intestinal infections caused by viruses such as norovirus, rotavirus, adenovirus, or astrovirus often resolve on their own within a few days. Some cases may last approximately 3 to 5 days.

Bacterial infections, such as those caused by salmonella or shigella, have varying recovery times depending on the specific bacteria and the severity of the illness. Most cases improve within about one week with appropriate care and treatment. However, symptoms often persist in severe infections, cases with inadequate treatment, or individuals with underlying conditions or compromised immune systems.

Intestinal infections caused by parasites (cryptosporidium, giardia, or amoebic dysentery due to entamoeba histolytica) can last over 2 to 6 weeks if not properly diagnosed and treated.

Beyond the pathogen, recovery time also depends on age, infection severity, body resistance, immune status, ability to rehydrate and replenish electrolytes, nutritional regimen, and the timing and method of treatment.

You have not provided specific information about the cause or current treatment and care, so the doctor cannot accurately predict your recovery time.

To recover quickly from an intestinal infection, you should drink enough water and may use oral rehydration solutions if you experience significant diarrhea or vomiting. Eat soft, easily digestible foods, divided into several small meals. Avoid self-medicating with anti-diarrhea drugs or antibiotics. Improper use can mask symptoms, cause side effects, or prolong the illness.

Individuals experiencing diarrhea or vomiting that persists for more than 2 to 3 days without improvement, high fever, severe abdominal pain, unusual bowel movements, or dehydration should seek early medical attention to avoid complications.
