Persistent Watery Diarrhea After Flu: When to See a Gastroenterologist?

The bowel movements are all watery?

I would like to ask the doctor, I was diagnosed with influenza A two days before New Year's Eve (the night before seeing the doctor, I experienced diarrhea and felt nauseous).
I have been taking cold medicine and antiviral medication for about 8 days (I have seen the doctor three times), but during the New Year, shortly after eating, I feel the urge to use the bathroom, and my stools are all watery.
Additionally, I am frequently passing gas.
Should I see a gastroenterologist for an examination?

More Info

Persistent watery diarrhea following a flu infection can be concerning, especially if it continues for an extended period. Given your history of A-type influenza and the symptoms you are experiencing, it is advisable to consult a gastroenterologist. Here’s why:
1. Understanding the Symptoms: After a viral infection like influenza, it is not uncommon for gastrointestinal symptoms to manifest. This can include diarrhea, abdominal discomfort, and increased flatulence. The flu can disrupt the normal functioning of the gastrointestinal tract, leading to conditions such as viral gastroenteritis. This is often characterized by watery diarrhea, which can persist even after the flu symptoms have resolved.

2. Duration of Symptoms: You mentioned that you have been experiencing watery diarrhea for about eight days. While some cases of viral gastroenteritis can resolve within a few days, persistent diarrhea lasting more than a week warrants further evaluation. Prolonged diarrhea can lead to dehydration and electrolyte imbalances, which can be serious if not addressed.

3. Potential Complications: In some cases, a viral infection can lead to secondary bacterial infections or complications such as post-infectious irritable bowel syndrome (IBS). Symptoms like frequent watery stools and gas can indicate that your gut flora is still recovering or that there may be an underlying issue that needs to be addressed.

4. When to Seek Medical Attention: It is essential to seek medical attention if you experience any of the following:
- Signs of dehydration (such as excessive thirst, dry mouth, little or no urination, severe weakness, or dizziness).

- Blood in your stool or black, tarry stools.

- Severe abdominal pain or cramping.

- A high fever that persists.

- Symptoms that worsen or do not improve after a few days.

5. What to Expect at the Gastroenterologist: When you see a gastroenterologist, they may perform a thorough evaluation, which could include:
- A detailed medical history and physical examination.

- Stool tests to check for infections, parasites, or blood.

- Blood tests to assess for dehydration and electrolyte imbalances.

- Imaging studies or endoscopic procedures if necessary, to rule out other gastrointestinal conditions.

6. Self-Care Measures: While waiting for your appointment, it is crucial to stay hydrated. Drink plenty of fluids, such as water, oral rehydration solutions, or clear broths. Avoid dairy products, caffeine, and high-fat or high-sugar foods, as these can exacerbate diarrhea. Eating bland foods like bananas, rice, applesauce, and toast (the BRAT diet) can also help.

In conclusion, while it is common to experience gastrointestinal disturbances after a viral infection like the flu, persistent watery diarrhea for over a week should not be ignored. Consulting a gastroenterologist will help ensure that any underlying issues are addressed and that you receive appropriate treatment to alleviate your symptoms and restore your gut health.
