Crohn’s disease is an inflammatory bowel disease in which the immune system attacks the lining of the intestine, usually the ending of the small intestine (called the ileum) or the colon. But it's more than just a case of irritable bowels. Crohn's disease symptoms range from abdominal cramps to ulcers that eat through the intestinal wall, and the complications—including pain, diarrhea, and malnutrition—can be sometimes be fatal. But with a proper diagnosis and the right medical care, managing the condition is possible for patients with Crohn’s. Here are more facts about Crohn's disease, from testing to treatments.

1. Crohn's disease causes are unknown, but genetics may be involved.

The exact causes of Crohn’s disease haven’t been identified, but for many people, family history plays a role. About 15 percent of Crohn’s patients share the diagnosis with a first-degree relative (parent, sibling, or child). Whether the family cluster patterns have more to do with genetics or environment is still unclear, though environmental factors appear to have more of an impact on the development of Crohn's disease symptoms. Scientists have also identified more than 200 gene variants that could influence Crohn's disease risk, mostly affecting genes related to immune system function.

2. Crohn's disease symptoms can come and go.

Crohn’s disease is characterized by inflammation of the digestive tract, and common signs include abdominal pain, rectal bleeding, diarrhea, fatigue, and fever. In severe cases, the inflammation can cause ulcers in the intestinal wall that prevents nutrient absorption, which can lead to weight loss and malnutrition. The intensity of these symptoms can be unpredictable. Flare-ups of gastrointestinal distress can last weeks to months, and there can also be long stretches of time when patients live symptom-free. Anti-inflammatory treatments can encourage the symptoms to go into remission, but the disease can never be cured completely.

3. Your diet can make Crohn's disease symptoms worse.

Doctors used to think of diet as one of the main causes of Crohn’s disease, but now it’s just thought to be a factor that exacerbates the symptoms. Certain foods can aggravate the digestive systems of people with Crohn’s. High-fiber foods, such fruits, vegetables, and whole grains, are some of the worst culprits, though cooked fruits and vegetables are generally gentler on the GI tract than raw ones.

4. Crohn's disease and ulcerative colitis are not the same.

People commonly confuse ulcerative colitis (UC) and Crohn’s disease. The two conditions are both inflammatory bowel diseases (which are different than irritable bowel syndrome, or IBS, which involves intestinal muscle contractions rather than inflammation). Both UC and Crohn's disease share symptoms such as weight loss, rectal bleeding, and diarrhea. But they differ in important ways: UC is limited to the large intestine, while Crohn’s disease can develop anywhere on the gastrointestinal tract between the mouth and anus. UC inflammation is also concentrated on the innermost intestinal lining, whereas can Crohn’s can penetrate the entire bowel wall. If you suspect you have an IBD, a doctor can help you identify the exact condition.

5. Crohn's disease can also affect the joints, eyes, and skin.

Crohn’s disease is known as a gastrointestinal disease, but the symptoms can extend beyond the digestive tract. People experiencing inflammation in the colon can also have inflammation in the joints. Up to 25 percent of patients with Crohn’s or UC also suffer from arthritis. Other complications include inflammation of the skin and eyes. Because eye tissue is so sensitive, ocular symptoms like redness and itchiness often appear before the first gastrointestinal signs.

6. A fecal occult blood test is one way to diagnose Crohn's disease.

There’s no one test for Crohn’s disease. Instead, doctors diagnose the condition by performing a series of tests to rule out other possible ailments. Testing poop samples with a fecal occult blood test can reveal hidden (or occult) blood in a patient’s stool, and testing antibodies can indicate whether symptoms are caused by Crohn’s or UC. Imaging tests—such as an ultrasound, MRI, X-ray, CT scan, or colonoscopy—gives doctors visual clues to the extent of a patient’s condition.

7. Incidence of Crohn's disease is increasing.

Crohn’s affects people of all ages, but symptoms usually appear in younger patients: People in the 15-to-35 age group are most likely to be diagnosed with the condition. Childhood cases of Crohn’s disease can lead to complications like delayed growth. Some studies have shown that the disease is becoming more prevalent, especially in Western countries and in children. Researchers think the "Westernized lifestyle" of poor-quality diet and lack of exercise are contributing factors to the increase.

8. Crohn's disease complications can be deadly.

If left untreated, Crohn’s disease can lead to some life-threatening complications. Inflammation can permanently damage the intestines, scarring parts the GI tract and causing tissue to thicken. In some cases, the damage is so severe that the bowel becomes blocked and surgery is required to remove the obstruction. Another possible complication is a fistula: an ulcer that has penetrated the intestinal wall and connected into a different part of the body, such as another organ or skin. An infected fistula is potentially fatal if ignored. Crohn's disease also increases a patient's risk of developing colorectal cancer. Inflammatory bowel disease is the third highest risk factor for colorectal cancer cases, though IBD-related cancer incidence is decreasing in some countries.

9. Surgery is a last resort for Crohn's disease.

Though Crohn’s disease can’t be cured, it can be managed. Most patients are initially put on anti-inflammatory medications. Other drugs, like pain relievers, nutritional supplements, and anti-diarrheal medications, are prescribed to treat the symptoms of the disease. If the condition doesn't improve, patients may require surgery to remove damaged portions of the bowel, close fistulas, and drain abscesses. Doctors may also recommend specific dietary changes to avoid flare-ups.

10. Crohn's disease was identified in the 1930s.

In 1932, gastroenterologist Burrill B. Crohn and his colleagues Leon Ginzburg and Gordon D. Oppenheimer identified the condition now known as Crohn’s disease, which Crohn called ileitis (meaning inflammation of the ileum). Prior to the report, the condition was thought to be type of a tuberculosis and not an inflammatory bowel disease. In addition to helping define the disease that bears his name, Crohn was one of the first medical professionals to link gastrointestinal distress to anxiety. He also published a book with the charming title Affections of the Stomach in 1927 and commented in media reports when President Dwight D. Eisenhower came down with ileitis symptoms in 1956.

7 Weird Super Bowl Halftime Acts

Shakira and Jennifer Lopez seem like natural choices to perform the halftime show at this year’s Super Bowl, but the event didn’t always feature musical acts from major pop stars. Michael Jackson kicked off the trend at Super Bowl XXVII in 1993, but prior to that, halftime shows weren’t a platform for the hottest celebrities of the time. They centered around themes instead, and may have featured appearances from Peanuts characters, Jazzercisers, or a magician dressed like Elvis. In honor of Super Bowl LIV on February 2, we’ve rounded up some of the weirdest acts in halftime show history.

1. Return of the Mickey Mouse Club

The era of Super Bowl halftimes before wardrobe malfunctions, illuminati conspiracy theories, and Left Shark was a more innocent time. For 1977’s event, the Walt Disney Company produced a show that doubled as a squeaky-clean promotion of its brand. Themed “Peace, Joy, and Love,” the Super Bowl XI halftime show opened with a 250-piece band rendition of “It’s a Small World (After All).” Disney also used the platform to showcase its recently revamped Mickey Mouse Club.

2. 88 Grand Pianos and 300 Jazzercisers

The theme of the halftime show at Super Bowl XXII in 1988 was “Something Grand.” Naturally, it featured 88 tuxedoed pianists playing 88 grand pianos. Rounding out the program were 400 swing band performers, 300 Jazzercisers, 44 Rockettes, two marching bands, and Chubby Checker telling everyone to “Twist Again."

3. Elvis Impersonator Performs the World’s Largest Card Trick

Many of the music industry's most successful pop stars—like Prince, Madonna, and, uh, Milli Vanilli—were at the height of their fame in 1989, but none of them appeared at Super Bowl XXIII. Instead, the NFL hired an Elvis Presley-impersonating magician to perform. The show, titled “BeBop Bamboozled,” was a tribute to the 1950s, and it featured Elvis Presto performing “the world’s largest card trick.” It also may have included the world's largest eye exam: The show boasted 3D effects, and viewers were urged to pick up special glasses before the game. If the visuals didn't pop like they were supposed to, people were told to see an eye doctor.

4. The Peanuts Salute New Orleans

Super Bowl XXIV featured one of the last halftime acts that was completely devoid of any musical megastars. The biggest celebrity at the 1990 halftime show was Snoopy. Part of the show’s theme was the “40th Anniversary of 'Peanuts,'” and to celebrate the milestone, performers dressed as Peanuts characters and danced on stage. The other half of the theme was “Salute to New Orleans”—not necessarily the first thing that comes to mind when you think of the comic strip.

5. A Tribute to the Winter Olympics

Super Bowl XXVI preceded the 1992 Winter Olympics—a fact that was made very clear by the event’s halftime. The show was titled “Winter Magic” and it paid tribute to the winter games with ice skaters, snowmobiles, and a cameo from the 1980 U.S. hockey team. Other acts, like a group of parachute-pants-wearing children performing the “Frosty the Snowman Rap,” were more generally winter-themed than specific to the Olympics. About 22 million viewers changed the channel during halftime to watch In Living Color’s Super Bowl special, which may have convinced the NFL to hire Michael Jackson the following year.

6. Indiana Jones and the Temple of the Forbidden Eye

“Peace, Joy, and Love” wasn’t the only Disney-helmed Super Bowl halftime. In 1995, Disney produced a halftime show called “Indiana Jones and the Temple of the Forbidden Eye” to tease the new Disneyland ride of the same name. It centered around a skit in which actors playing Indiana Jones and Marion Ravenwood stole the Vince Lombardi Trophy from an exotic temple, and it included choreographed stunts, fiery special effects, and a snake. Patti LaBelle and Tony Bennett were also there.

7. The Blues Brothers, Minus John Belushi

The 1990s marked an odd period for halftime shows as they moved from schlocky themed variety shows to major music events. Super Bowl XXXI in 1997 perfectly encapsulates this transition period. James Brown and ZZ Top performed, but the headliners were the Blues Brothers. John Belushi had been dead for more than a decade by that point, so Jim Belushi took his place beside Dan Aykroyd. John Goodman was also there to promote the upcoming movie Blues Brother 2000. The flashy advertisement didn’t have the impact they had hoped for and the film was a massive flop when it premiered.

11 Behind-the-Scenes Secrets of TV Meteorologists

The first weather forecast to hit national network television was given in 1949 by legendary weatherman Clint Youle. To illustrate weather systems, Youle covered a paper map of the U.S. in plexiglass and drew on it with a marker. A lot has changed in the world of meteorology since then, but every day, millions of families invite their local weatherman or weatherwoman into their living room to hear the forecast. Here are a few things you might not know about being a TV meteorologist.

1. SOME PEOPLE JUST NEVER MASTER THE GREEN SCREEN.

On-camera meteorologists might look as if they’re standing in front of a moving weather map, but in reality, there’s nothing except a blank green wall behind them. Thanks to the wonders of special effects, a digital map can be superimposed onto the green screen for viewers at home. TV monitors situated just off-camera show the meteorologist what viewers at home are seeing, which is how he or she knows where to stand and point. It’s harder than it looks, and for some rookie meteorologists, the learning curve can be steep.

“Some people never learn it,” says Gary England, legendary weatherman and former chief meteorologist for Oklahoma’s KWTV (England was also the first person to use Doppler radar to warn viewers about incoming systems). “For some it comes easily, but I’ve seen people never get used to it.”

Stephanie Abrams, meteorologist and co-host of The Weather Channel’s AMHQ, credits her green screen skills to long hours spent playing Nintendo and tennis as a kid. “You’ve gotta have good hand-eye coordination,” she says.

2. THEY HAVE A STRICT DRESS CODE.

Green is out of the question for on-air meteorologists, unless they want to blend into the map, but the list of prohibited wardrobe items doesn’t stop there. “Distracting prints are a no-no,” Jennifer Myers, a Dallas-based meteorologist for Oncorwrites on Reddit. “Cleavage angers viewers over 40 something fierce, so we stay away from that. There's no length rule on skirts/dresses but if you wouldn't wear it to a family event, you probably shouldn't wear it on TV. Nothing reflective. Nothing that makes sound.”

Myers says she has enough dresses to go five weeks without having to wear a dress twice. But all the limitations can make it difficult to find work attire that’s fashionable, looks good on-screen, and affordable. This is especially true for women, which is why when they find a garment that works, word spreads quickly. For example, this dress, which sold for $23 on Amazon, was shared in a private Facebook group for female meteorologists and quickly sold out in every color but green.

3. BUT IT’S CASUAL BELOW THE KNEE.

Since their feet rarely appear on camera, some meteorologists take to wearing casual, comfortable footwear, especially on long days. For example, England told the New York Times that during storm season, he was often on his feet for 12 straight hours. So, “he wears Mizuno running shoes, which look ridiculous with his suit and tie but provide a bit of extra cushioning,” Sam Anderson writes.

And occasionally female meteorologists will strap their mic pack to their calves or thighs rather than the more unpleasant option of stuffing it into their waistband or strapping it onto their bra.

4. THERE ARE TRICKS TO STAYING WARM IN A SNOWSTORM.

“In the field when I’m covering snow storms, I go to any pharmacy and get those back patches people wear, those heat wraps, and stick them all over my body,” explains Abrams. “Then I put on a wet suit. When you’re out for as long as we are, that helps you stay dry. I have to be really hot when I go out for winter storms.”

5. THERE’S NO SCRIPT.

Your local TV weather forecaster is ad-libbing from start to finish. “Our scripts are the graphics we create,” says Jacob Wycoff, a meteorologist with Western Mass News. “Generally speaking we’re using the graphics to talk through our stories, but everything we say is ad-libbed. Sometimes you can fumble the words you want to say, and sometimes you may miss a beat, but I think what that allows you to do is have a little off-the-cuff moment, which I think the viewers enjoy.”

6. MOM’S THE AUDIENCE.

Part of a meteorologist’s job is to break down very complicated scientific terminology and phenomena into something the general public can not only stomach, but crave. “The trick is … to approach the weather as if you're telling a story: Who are the main actors? Where is the conflict? What happens next?” explains Bob Henson, a Weather Underground meteorologist. “Along the way, you have the opportunity to do a bit of teaching. Weathercasters are often the only scientists that a member of the public will encounter on a regular basis on TV.”

Wycoff’s method for keeping it simple is to pretend like he’s having a conversation with his mom. “I’d pretend like I was giving her the forecast,” he says. “If my mom could understand it, I felt confident the general audience could as well. Part of that is also not using completely science-y terms that go over your audience’s head.”

7. SOCIAL MEDIA HAS MADE THEIR JOBS MORE DIFFICULT.

Professional meteorologists spend a lot of time debunking bogus forecasts spreading like wildfire across Twitter. “We have a lot of social media meteorologists that don’t have necessarily the background or training to create great forecasts,” Wycoff says. “We have to educate our viewers that they should know the source they’re getting information from.”

“People think it’s as easy as reading a chart,” says Scott Sistek, a meteorologist and weather blogger for KOMO TV in Seattle. “A lot of armchair meteorologists at home can look at a chart and go ok, half an inch of rain. But we take the public front when it’s wrong.”

8. THEY MAKE LIFE-OR-DEATH DECISIONS.

People plan their lives around the weather forecast, and when a storm rolls in, locals look to their meteorologist for guidance on what to do. If he or she gets the path of a tornado wrong, or downplays its severity, people’s lives are in danger. “If you miss a severe weather forecast and someone’s out on the ball field and gets stuck, someone could get injured,” says Wycoff. “It is a great responsibility that we have.”

Conversely, England says when things get dangerous, some people are reluctant to listen to a forecaster’s advice because they don’t like being told what to do. He relies on a little bit of psychological maneuvering to get people to take cover. “You suggest, you don’t tell,” he says. “You issue instructions but in a way where they feel like they’re making up their own minds.”

9. DON’T BANK ON THOSE SEVEN-DAY FORECASTS.

“I would say that within three days, meteorologists are about 90 percent accurate,” Wycoff says. “Then at five days we’re at about 60 percent to 75 percent and then after seven days it becomes a bit more wishy-washy.”

10. THEY’RE FRENEMIES.

The competition for viewers is fierce, and local meteorologists are all rivals in the same race. “When you’re in TV, all meteorologists at other competitors are the enemy,” England says. “You’re not good friends with them. They try to steal the shoes off your children and food off your plate. If they get higher ratings, they get more money.”

11. THEY’RE TIRED OF HEARING THE SAME JOKE OVER AND OVER.

“There’s always the running joke: ‘I wish I could be paid a million dollars to be wrong 80 percent of the time,’” Sistek says. “I wanted to have a contest for who can come up with the best weatherman insult, because we need something new! Let’s get creative here.”
