Dangerous Flu Symptoms You Should Never Ignore

Woman with flu symptomsMost cases of the flu are a nuisance — you’ll be on your back for a few days or weeks, and then you can return to your normal routine. But certain flu symptoms, like sudden dizziness, may signal a more serious medical problem, like sepsis or pneumonia.

Make sure you know how to differentiate normal symptoms from serious ones and when to seek help, so you can prevent a potentially life-threatening situation.

Normal Flu Symptoms

There are some telltale signs of the flu that most people can expect to experience, though not everyone will have all symptoms. These include:

These prescriptions can minimize symptoms, shorten the time you have the flu by one or two days and prevent major complications.

If you’re in a high-risk group, you should call your doctor at the first sign of the flu. And, if you’re very sick or worried about your symptoms, it’s best to go ahead and see your doctor. Antiviral medications work best if you start them within the first two days of symptom onset.

Getting the flu vaccine and practicing healthy habits — like washing your hands regularly, avoiding sick people and eating a healthy diet — can help prevent the disease and keep germs from spreading. But if you do happen to contract the flu, here’s what you should do:

The flu virus should be taken very seriously, especially for children and the elderly. While most will recover within a couple of weeks, you should keep your doctor in the loop if you’re symptoms don’t improve.
