Does the flu have you running to the bathroom more often than usual?
Here’s what you need to know about diarrhea as a possible flu symptom.
What is diarrhea?
Diarrhea is a common condition characterized by loose, watery stools that occur more frequently than usual. Essentially, it is the body’s way of dealing with disruptions in the gastrointestinal system, which can have a wide range of causes, such as:
- Infections (such as those caused by bacteria, viruses, or parasites)
- Food intolerances
- Digestive disorders like irritable bowel syndrome (IBS)
In many cases, diarrhea serves as a symptom rather than a disease itself, whichsignals an underlying issue that needs attention.
The condition can be classified into two types: acute and chronic.
- Acute diarrhea. Thisis a short-term type of diarrhea that often lasts a few days and typically resolves on its own.It’s commonly caused by infections or food poisoning.
- Chronic diarrhea. Compared to acute diarrhea, this type lasts for at least four weeks and is usually related to functional disorders such as IBS or inflammatory bowel diseases like Crohn’s disease or ulcerative colitis.
While many episodes of acute diarrhea can be managed with hydration and diet modifications, chronic diarrhea may require medical intervention to address its underlying cause.
What is flu?
The flu, orinfluenza, is a highly contagious respiratory illness caused by influenza viruses. It impacts the nose, throat, and sometimes the lungs, leading to a range of symptoms from mild to severe.
Key symptoms include:
- Fever
- Cough
- Sore throat
- Runny or stuffy nose
- Muscle or body aches
- Headaches
- Fatigue
While most people recover within a week to ten days, the flu can lead to severe complications, particularly in these populations:
- Young children
- The elderly
- Pregnant women
- Those with chronic health conditions
- Those with weakened immune systems
Flu viruses propagate mainly through tiny droplets released when infected individuals cough, sneeze, or talk. These droplets can land in your mouth or nose, or you can also inhale them into your lungs.
In some cases, you might also contract the flu by touching a surface or object that has the flu virus on it and then touching your mouth, nose, or eyes
Is diarrhea a flu symptom?
While diarrhea is not a hallmark symptom of the flu, it can occur as a secondary symptom, especially in children.
For adults, the flu usually manifests through symptoms like fever, cough, sore throat, and muscle aches.
In contrast, children may also experience gastrointestinal symptoms, including:
- Diarrhea
- Vomiting
- Nausea
How does the flu cause diarrhea?
While the flu primarily targets the respiratory system, it can also impact the gastrointestinal tract and increase bowel movements, leading to diarrhea.
While more commonly observed in children, this effect can occur in individuals of all ages, depending on the individual’s immune response and the specific strain of the flu virus involved.
What is the difference between the flu andstomach flu?
The term “flu” refers to influenza, a respiratory illness caused by influenza viruses. In contrast, “stomach flu” is a misnomer for gastroenteritis, an inflammation of the gastrointestinal tract caused by various viruses, bacteria, or parasites.
Gastroenteritis symptoms focus on the digestive system rather than the respiratory system, including:
- Diarrhea
- Vomiting
- Abdominal pain
How do you manage diarrhea when you have the flu?
Dealing with diarrhea while battling the flu can make you feel miserable. Fortunately, there are ways to manage the discomfort and help your body recover. Here are some key steps to help you get through it:
- Stay hydrated.Diarrhea causes fluid loss, so it’s essential to drink plenty of clear fluids like water, broth, or oral rehydration solutions to replenish fluids and electrolytes.
- Rest. Allow your body to rest so it can focus on fighting the flu and supporting your immune system.
- Use over-the-counter medications cautiously. Medications like loperamide can help manage symptoms, but it’s best to use them under medical advice, especially for children.
- Follow the BRAT diet. Eating bananas, rice, applesauce, and toast can soothe your digestive tract. These foods are low in fiber, easy to digest, and can help reduce the intensity of diarrhea.
- Avoid irritants. Stay away from dairy, caffeine, and spicy foods to prevent further irritation to your gastrointestinal system.
- Consult a healthcare provider. If diarrhea persists or worsens, seek medical advice to prevent dehydration and other complications.
When should you see a doctor?
While most cases of flu-related diarrhea can be managed at home, certain signs require professional attention. If you experience any of the following, it’s recommended to seek medical advice as soon as possible:
- Severe dehydration symptoms.These include signs like dizziness, dry mouth, or low urine output.
- Diarrhealasting more than two days. If diarrhea persists beyond 48 hours, it may be a sign of complications.
- High fever. A fever above 102°F (39°C) in conjunction with diarrhea requires medical attention.
- Blood in stool. The presence of blood in the stool is a red flag for a more serious issue.
- Severe abdominal pain. Intense stomach cramps or pain that doesn’t subside could indicate a need for medical care.
These symptoms may indicate that your body is struggling to handle the infection, and a healthcare provider can help ensure a safe recovery.
Frequently asked questions
Is diarrhea a common symptom of the flu?
Diarrhea is not typically a primary symptom of influenza, which primarily affects the respiratory system. However, some individuals, especially children, may experience gastrointestinal symptoms, including diarrhea, with a flu infection.
Can the flu cause gastrointestinal symptoms?
Yes, while the flu primarily causes respiratory symptoms, influenza can also lead to gastrointestinal issues, such as nausea, vomiting, and diarrhea, particularly in children.
How does the flu virus lead to diarrhea?
The flu virus may disrupt the normal function of the gastrointestinal tract, leading to increased movement within the intestines. This disruption can result in diarrhea among other gastrointestinal symptoms.
Should individuals with the flu and diarrhea seek medical attention?
Individuals experiencing diarrhea along with flu symptoms should consider seeking medical attention, especially if dehydration, persistent vomiting, or severe discomfort occurs. Vulnerable populations, such as young children and the elderly, are at higher risk.
How can you differentiate between the flu and stomach flu symptoms?
Influenza (flu) primarily causes respiratory symptoms, such as coughing and sore throat. Stomach flu, or gastroenteritis, mainly leads to gastrointestinal symptoms, including diarrhea, vomiting, and stomach cramps. Both may share symptoms like fever and body aches.
Key takeaway
While diarrheaisn’t one of the first symptoms associated with the flu, it’s clear that for some people, especially children, it can make an unwelcome appearance.
