The number of Americans searching online for information on hemorrhoids and how to treat them seems to have skyrocketed since 2008.
Data gathered from Google searches show that interest in the term "hemorrhoids" more than doubled between 2008 and 2013, according to a LiveScience analysis using Google Trends, a tool that shows how often a particular search term is entered in the search engine, relative to the total search volume in a specific country.
The term "hemorrhoids" was searched about 40,000 times weekly between 2004 and 2008, but this number started to rise during mid-2008, crept up to about 80,000 weekly searches in 2010, and reached nearly 120,000 during some weeks in 2013.
"My first guess would be that people are becoming more comfortable with the Internet, and they are going to look up more and more things, and hemorrhoids are a common condition," said Dr. Jesse Moore, an assistant professor of surgery at University of Vermont College of Medicine, and attending surgeon at Fletcher Allen Health Care in Burlington, VT.
In fact, one in three American adults have reported going online to try to figure out what medical condition they or someone else might have, according to a national survey conducted earlier this year by Pew Research Center.
It seems possible that conditions such as hemorrhoids might be among the most searched-for online because people may be embarrassed to talk about them with a doctor. But perhaps they shouldn't be: Technically, everybody has hemorrhoids. [7 Embarrassing Health Problems]
What are hemorrhoids?
"One of the misconceptions about hemorrhoids is that 'nobody has it but me.' Actually, everybody has hemorrhoids, but not everybody has symptoms of hemorrhoids," Moore told LiveScience.
Hemorrhoids are normal parts of the human anatomy, and they serve a purpose. These little blood vessels act like water balloons inside the lower rectum, and help people control bowel movements.
But sometimes, hemorrhoids can become swollen or inflamed, causing symptoms such as bleeding or pain.
"I see a lot of people in my office with complaints of hemorrhoids. Only about half of the time is it actually that they have hemorrhoids that are symptomatic," Moore said. Because other conditions can cause the same symptoms, many people mistakenly think they have hemorrhoids.
The most common condition that people mistake for hemorrhoids are fissures, Moore said. Both can cause bleeding.
Fissures, which are tears in the skin of the lower rectum, are usually treated with topical medication applied to the surface of the fissure. However, some patients need surgery, he said.
Dr. Jeffrey S. Aronoff, a colorectal surgeon at Lenox Hill Hospital in New York, said he suspects people may be increasing searching for hemorrhoid information because advertisements about hemorrhoid treatment services are becoming more common.
"It's important that people be aware where they educate themselves about medical issues," because some health websites have inaccurate information, Aronoff said.
The best way to avoid getting symptomatic hemorrhoids or fissures is to avoid constipation and prolonged straining on the toilet. People should eat a high-fiber diet, consuming about 30 grams of fiber, as well as drinking about 2 liters of water a day, Moore said.
Fruits such as apples and pears (with skin) have about 4 to 5 grams of fiber. A bowl of a high-fiber cereal might have up to 8 grams, and a cup of cooked peas, lentils or beans has up to 15 grams of fiber. But there are certain foods that are constipating and should be avoided if people start having problems (bananas, for example).
When too much pressure is positioned on the blood vessels in the rectal area, hemorrhoids may bulge or become swollen. Pregnancy, heavy lifting, and long hours of sitting can increase blood flow into the hemorrhoids and result in their engorgement, increasing the risk of developing symptomatic hemorrhoids, Aronoff said.

How can hemorrhoids be treated
Hemorrhoids come in two types; there's internal and there's external hemorrhoids, Moore said.
Internal hemorrhoids cause painless bleeding. One treatment option for internal hemorrhoids is to use what is called "rubberbanding," which is strangling the hemorrhoid by tying a rubber band at its base, cutting off the blood flow to the hemorrhoid. This is an outpatient procedure that a doctor performs in the office.
External hemorrhoids happen when hemorrhoids become irritated, and blood clots form under the skin. This is called a thrombosed, or clotted, hemorrhoid, and is painful and can bleed. The usual treatment for external hemorrhoids is to excise them.
"Over-the-counter stuff that people see advertised for hemorrhoids have never been shown in any good scientific study to help hemorrhoids," he said.
Generally, if people see blood in the stool, it's important to see a doctor, especially if they are over 40 years old. A doctor could help make sure the blood is from a hemorrhoid or a fissure, and not from a tumor in the colon, doctors said.
Also, when people experience discomfort in their rectal area, which could be caused by symptomatic hemorrhoids, fissures, warts or other conditions, it's a good idea to see a doctor who can help diagnose the problem.
"A lot of times it's not actually hemorrhoids, and would respond to different treatments," Moore said.

How Much We Know And Care About CPR, AEDs And Cardiac Arrest
In two new studies, researchers from the University of Pennsylvania have found that people are tweeting about cardiac arrest, CPR and AEDS (automated external defibrillators), and that the microblogging platform has the potential to spread more awareness and spur more discussion on the topics. The research was presented this month at the annual <a href="http://scientificsessions.org/" target="_hplink">Scientific Sessions</a> meeting of the American Heart Association. In one of the studies, researchers sought to find out what exactly <a href="http://circ.ahajournals.org/cgi/content/meeting_abstract/124/21_MeetingAbstracts/A53?sid=6e736fad-18a8-4580-8b6d-225308e637e6" target="_hplink">people were asking about cardiac arrest and CPR </a>on Twitter. They analyzed 13,981 tweets and found that 21 percent of cardiac arrest-related questions had to do with symptoms, prognosis or risk factors of the condition, and 39 percent of the questions had to do with guidelines, certification and proper technique of CPR. Forty percent of the questions had to do with costs, safety and use of AEDs. In the other study, researchers looked at 15,324 tweets that contained some sort of <a href="http://circ.ahajournals.org/cgi/content/meeting_abstract/124/21_MeetingAbstracts/A52?sid=6e736fad-18a8-4580-8b6d-225308e637e6" target="_hplink">information about cardiac arrest</a>. Among their findings: 14 percent of those tweets were a direct reference to a cardiac arrest, while 5 percent were personal stories of cardiac arrest. Twenty-nine percent of the tweets had to do with using CPR or an AED and almost 60 percent of the tweets had to do with training or advocacy events for cardiac arrest, or news about a celebrity, athlete or young adult who had undergone cardiac arrest.
What We Think About The Flu
A study published earlier this year in the journal <em>PLoS Computational Biology</em> shows that Twitter could be used to track <a href="http://www.huffingtonpost.com/2011/10/15/twitter-flu-shot-vaccinations_n_1010899.html" target="_hplink">flu shot vaccination rates</a> and attitudes. That research, conducted by Pennsylvania State researchers, involved analysis of 477,768 tweets between August 2009 and January 2010 that contained some sort of wordage about the H1N1 vaccine. The researcher was able to see what parts of the U.S. had the highest flu vaccination rates (based on the Twitter information), as well as what the general sentiments were toward the vaccine (New Englanders are most positive toward the vaccine, and are also the most likely to get vaccinated). Researchers also found that people were most negative toward the flu vaccine when it was first introduced, but then the reaction grew increasingly positive the more time passed.
What's Ailing Us -- And What We've Got Wrong About Our Health
Recent research from Johns Hopkins University in Baltimore shows that you can look on Twitter to get a <a href="http://www.huffingtonpost.com/2011/07/08/twitter-health_n_893466.html#s305983&title=Chris_Tung" target="_hplink">general feel for what ills people are experiencing</a>. They found in their study of 1.5 million health-related tweets that people are tweeting most about depression, cancer, obesity, allergies, insomnia and pain. Researchers also found that Twitter could be used to unearth some common health misconceptions we have. For example, "we found that some people tweeted that they were <a href="http://www.bbc.co.uk/news/technology-14059745" target="_hplink">taking antibiotics for the flu</a>," Ph.D. student Michael J. Paul, one of the researchers for the project, told BBC News. "But antibiotics don't work on the flu, which is a virus, and this practice could contribute to the growing antibiotic resistance problems."
How We're Feeling
Turns out, we're <a href="http://www.huffingtonpost.com/2011/09/29/twitter-mood-study_n_987569.html" target="_hplink">happiest early in the morning</a> and around midnight, according to a Twitter study conducted by Cornell University researchers. Researchers looked at half a billion tweets from more than 2 million Twitter users over a two-year period, and found that Twitter users' <a href="http://www.huffingtonpost.com/2011/09/29/twitter-mood-study_n_987569.html" target="_hplink">moods tend to start happy</a> early in the day and then get more negative as the day wears on, but then peak again in happiness at midnight. "Everybody we told about this has had the same reaction: 'That's obvious. People go to work, they get stressed -- of course their mood deteriorates,'" study researcher Michael Macy, Ph.D., a professor of sociology at Cornell, told HuffPost. "It turns out, that's not true." Because researchers found that the "daily mood swing" unearthed by Twitter was also the case during the weekends, they suggest that the changes in emotions might be affected by our sleep and circadian rhythms, and not just a bad mood brought on by the workday.
What We Understand (And Misunderstand) About Antibiotics
What we <a href="http://www.ajicjournal.org/article/S0196-6553(10)00034-9/abstract" target="_hplink">think we know about antibiotics</a> is very easily spread through Twitter, according to a study published last year in <em>AJIC: American Journal of Infection Control</em>. However, the viral nature of Twitter has the ability to backfire if the antibiotic information isn't correct, researchers said. The study, conducted by Columbia University and MixedInk researchers, looked at 52,153 <a href="http://www.ajicjournal.org/article/S0196-6553(10)00034-9/abstract" target="_hplink">tweets that mentioned antibiotics</a> that were posted between March 13, 2009 and July 31, 2009. Researchers used word combinations like "extra + antibiotic(s)" and "leftover + antibiotic(s)" to narrow down the tweets further. They found that when it came to tweeting about antibiotics, people were most commonly talking about how many days they had left on an antibiotic regimen, or a desire that antibiotics help to kick an illness soon. The second most common topic was advice on antibiotics, and the third most common topic was side effects that come from taking antibiotics. Out of all the tweets, 700 were spreading some sort of misunderstanding about antibiotics, researchers found. For example: the word combination of "flu + antibiotic(s)" yielded 345 tweets, which in turn reached a total of 172,571 Twitter followers.
