The dreaded flu season is once again upon America. There are several simple precautions that everyone should take, including frequently and thoroughly washing hands, trying to stay clear of those already infected with the flu virus, visiting the doctor or clinic for a flu vaccine and, as always, losing weight. Because carrying excess weight can compromise the immune system, even the common cold can last longer and result in more severe cold and flu symptoms for those that are overweight. During an influenza pandemic, it is very common for flu vaccines to become scarce, forcing patients to be qualified by a physician to receive the vaccine. Because the flu vaccines can take several months to develop and manufacture, including obese individuals very seldom makes it to the top of the priority list. US News reports that the flu can be minimized or avoided altogether with simple weight loss.
