What Does Having the Flu Do to Your Body

Getting sick is not fun for anyone, especially for people who suffer from liver damage or other health conditions.

According to the CDC, the exact time and duration of flu season can vary, but flu activity tends to increase around October, hitting the peak of the season from December to February. Here are a few key facts you should know about the flu:

  • The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and sometimes the lungs.
  • It is one of the most common infectious diseases in the world.
  • The flu can cause mild to severe illness, and at times can lead to death.
  • People with flu are most contagious in the first 3-4 days after their illness begins.
  • 172 child deaths were reported for the 2017-18 flu season.
  • Every year the flu sends more than 700,000 people to the hospital.

Your Body and the Flu

Your Liver - People with liver damage or other existing liver conditions are more vulnerable from the flu. This is because liver disease can weaken your body’s ability to fight the influenza virus and even make liver disease worse. In fact, evidence shows that people with liver conditions like hepatitis C have a higher risk of developing complications from the flu than those without it.

Your Head – Headaches are a common symptom of the flu and this is because of an inflammatory cytokine, called Interleukin-1, is activated. Though Interleukin-1 is necessary for developing the killer T cell that responds against the flu virus, it can affect the part of the brain that controls body temperature which can cause headaches and fever.

Your Muscles – Another common symptom of the flu is weakness and muscle aches. In a study, the flu led to an increase in the expression of muscle-degrading genes and a decline in the expression of muscle-building genes. Unfortunately, this is a result of the immune systems response to the influenza virus.

Your Lungs – According to research from the University of Alabama at Birmingham and Sothern Research Institute, the flu virus contains a protein that helps the virus multiply. This protein can cause damage to the lungs by causing a build-up of fluid.

Preventing Infection

The first step to take towards preventing complications with the flu virus is to get vaccinated. The flu vaccine can protect people with liver disease and other conditions the same way it can protect people without it. Getting the flu shot can lower your risk of infection and reduce the risk of severe complications for people with liver conditions.

Other things you can do to help prevent getting infected include:

  • Avoiding close contact with people who are sick
  • Wash your hands often
  • Clean an disinfect surfaces at home, school, and work frequently

The best way to stay healthy and prevent getting sick with viruses like the flu, is to live a healthy lifestyle. Keeping your body healthy allows it to function properly and help your immune system stay strong.
