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.

Considering how much Americans spend on food -- $151 per week -- it makes sense that "diet" was so heavily searched on Google.

Around eight in 10 people will experience back pain sometime in their lives, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
8. Allergies

The Google ranking did not differentiate between food allergies or allergies from the environment, but either way, both forms widely affect people in the U.S. Climate Nexus reported earlier this year that this year's spring was an especially bad one for allergies. And a recent JAMA Pediatrics study showed that the cost of childhood food allergies is a whopping $24.8 billion every year (via special diets, lost work productivity and medical care).

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.
