Here's your chance to be nosy and see what health issues people searched for the most this past year.
Google has released its 13th annual Zeitgest, showing the health topics people looked up the most on the search engine in 2013. Not surprisingly, conditions like cold and flu topped the chart (who didn't get sick this year, after all?). Check out the list below to see what else made the top 10 ranking.
Perhaps it's not surprising searches for "flu" topped the ranking, considering there were 31.8 million influenza-associated illnesses during the 2012-2013 flu season. The Centers for Disease Control and Prevention also said in a recent report that there were 14.4 million influenza illnesses that required medical attention and 381,000 hospitalizations from influenza illness last flu season.
Colds can be caused by a number of viruses, but the most common may be rhinovirus. Sore throat and runny nose are typical signs; colds differ from the flu in that flu symptoms include fever, muscle pain, sore throat and fatigue.
Diarrhea can be caused by any number of things, but common triggers include viruses, bacteria or parasites (often from contaminated food or drink). Lactose intolerance and some medications can also lead to diarrhea.
The cause of lupus, which is a chronic autoimmune disease affecting different parts of the body, is still a mystery today. As many as 1.5 million people in the U.S. have the condition, with 16,000 new cases being reported each year, according to the Lupus Foundation of America.
