What Is the Flu?

what is the flu

Most of us have caught the flu bug before. The flu, or influenza, is an illness caused by flu viruses which infect your nose, throat and lungs. When you are down with the flu, you show signs and symptoms that include fever, cough, sore throat and body ache.

Diabetes Can Turn Flu into a Serious Problem

For most people, the flu is usually mild and lasts only a few days. But if you have diabetes, the flu can lead to serious problems such as infection of the lung, ear and sinus. In severe cases, it can result in hospitalisation and may even lead to death.

Having the flu can also make it harder to control your blood glucose.

Protect Yourself and Get a Flu Vaccine

One of the best ways to protect yourself against the flu is to get a flu vaccine each year. It is safe and most people have no side effects.

Because it takes roughly two weeks for a vaccine to be effective, get your flu vaccine before peak flu season starts. In Singapore, the season is generally from December to February, and May to July.

Your doctor can advise you on the flu vaccine suitable for you. In addition, check with your doctor whether you should get the pneumococcal vaccine to protect against pneumonia.
