Ulcerative colitis and Crohn’s disease are the 2 major forms of inflammatory bowel disease. Both conditions are characterized by chronic inflammation of the gastrointestinal tract, or GI tract. Ulcerative colitis is limited only to the large intestine. It usually starts from the rectum, and may remain confined to that location; or, it can spread upward in a continuous fashion, affecting parts, or all, of the colon.
Crohn disease, on the other hand, can occur anywhere along the GI tract, but it usually involves the small intestine. Most commonly affected are the end of the small bowel, the ileum, and the beginning of the colon. Crohn disease is not continuous: inflamed segments are usually interrupted by normal healthy tissues. The rectum is always affected in ulcerative colitis, but is usually spared in Crohn’s disease.
Ulcerative colitis only involves the inner lining of the intestinal wall, while Crohn’s disease extends to its entire thickness. In imaging studies, the mucosa in Crohn’s disease has a patchy appearance, with alternating regions of diseased and normal tissues; the bowel wall is affected asymmetrically. In ulcerative colitis, mucosal inflammation is diffuse and uniform; the bowel wall is affected symmetrically. Thickening of the intestinal wall, bowel obstructions and fistulas are unique to Crohn’s disease.
Both conditions result from an inappropriate response of the immune system, but their mechanisms are likely different. Ulcerative colitis is associated with abnormally high levels of helper T-cell type 2, Th-2, while Crohn’s disease has more type 1 (Th1) activities.
Age of onset and risk factors are similar for both conditions, with a notable exception of smoking, which exacerbates Crohn’s disease but has a protective effect on ulcerative colitis.
The 2 disorders share many common symptoms such as diarrhea, abdominal pain and extra-intestinal manifestations. However, Crohn’s disease symptoms can be more variable depending on the affected locations, and often include anal fistulas and abscesses. Intestinal bleeding is much more common in ulcerative colitis, while malnutrition and weight loss is more common in Crohn’s disease.
When Crohn’s disease involves only the colon, the symptoms can be indistinguishable from ulcerative colitis. Fortunately, because treatment is similar, no distinction is necessary unless surgery is considered. This is because surgical removal of the diseased colon is curative for ulcerative colitis, but only provides temporary relief for Crohn’s disease.
This is my to-go RUclips page when I do not clearly understand something in class. Thank you for this material. Clear, basic, straightforward.
i know the cure i already cured mine i can eat whatever i want , without any medication only with exercise techques and diet , but literally no one beleives in me .GOD PROMISE i know the CURE.
I like this man's voice and the easy to understand explanation.
Yes such a soothing and reassuring voice
Excellent subject knowledge conveyed with simple terms
Thank you so much these information were very useful ❤
POV: you have one of the two and wanted to know what its like to have the other
POV trying to explain your condition to family 😂
Knowledge of the differences increases one's knowledge of one's own disease.
POV: you have both 🙂
Diet is a major factor, cut bread, sugar processed foods, I have uc and the carnivore diet has helped me greatly.
Carnivore diet such as meat??
@@jaytbutt1650 yes, but not processed
@@edwardkennedy9919are you ok now?
The body runs on carbohydrates... you cut carbs, you'll feel like crap. You should limit fat intake....red meats has high amounts of fats. I would avoid meats,
Being a chrohn's sufferer myself, this is an excellent video to show others what this nasty disease is.
Excellent info👌🏻 Greetings from Scotland 😊 Have a wonderful day everyone 🌻
solid and succinct comparison
Thank you 🙏 this was very helpful
The shitting blood to swallowing a mini-camera domino effect is something that genuinely blows my mind
As someone with IBD… this is extremely interesting
I think this is the worst disease you can have speaking with personal experience
@@jaytbutt1650 try to send disease to remission you can live normal life but this disease will never leave you alone m
As someone fighting ulcerative colitis, I can say that I’ve been able to get myself into remission by watching my diet and exercise. I do fasting to allow the ulcers in my body to heal and then avoid gluten, sugar and sometimes vegetables if I’m in pretty bad shape. Also take iron for blood loss and glutamine to heal the inside. I haven’t tried cabbage juice yet but I heard it’s pretty effective so trying that next.
@@amitpalbains9361 May I ask what kind of exercise helps you? And how light/intense is it?
Perfectly described thank you 😊
It’s Really amazing
nice explanation
Amazing!!!👍🏾
Very good video!!
Thanks
Thx
I know someone who had more than a metre of intestine surgically removed due to one of these two horrible illnesses. I watched the video to try and figure out which one it was but I'm more confused than ever. I'm pretty sure it was Crohn's though...
i know the cure i already cured mine i can eat whatever i want , without any medication only with exercise techniques and diet , but literally no one beleives in me .GOD PROMISE i know the CURE.
most likely crohns. UC doesn't require surgery most of the time
Understood 💯💯
So helpful!!
Nice video.
i know the cure i already cured mine i can eat whatever i want , without any medication only with exercise techniques and diet , but literally no one belives in me .GOD PROMISE i know the CURE.
II had this disease but I got over it
Are there books you followed that you feel comfortable sharing thank you
You don’t get over it. You go into remission. I was in remission for 10 years before it returned
This disease never leaves
It's your new best friend.
@@SniperPrecision when you eat right food u can stay healthy and happy
@salmaan_nutrition definately but it won't save you. Medication is vital. Diet helps tremendously. Had crohns for 8 years. Remission now for 2. Stelara saved me
I have UC I just found out and I have just quit smoking
Thank u sir

Oh , so sad to hear this . I also got pain in my left got sudden pain in my left abdominal and my colonoscopy and endoscopy revealed it to be ulcerative colitis but yeah the biopsies haven't come yet but I can understand your pain.
I hope u get better soon
I’m not a doctor so what I’m saying might not apply to you. I was recently diagnosed with ulcerative colitis. It was terrible especially for me who travels a lot for work. What I’ve learned after watching a of videos, success stories and visiting many doctors: you’re general doctor are pretty clueless about these conditions. My main doctor who’s supposed to be an expert in this field said there’s nothing that can be done here’s a steroid to help you control it. I see an iridologist and he said it all starts with stress and diet. I’ve taken gluten and sugar out of my diet and mostly eat meat along with fasting to help my insides recover and am in much better shape. I take quite a bit of natural medicine/vitamins but the main source of my healing is diet, exercise and managing stress. And my diet was never truly bad to begin with.
@@unicorn3241what are symptoms did you experience?
@bobmuneer7829 well a sharp stomach pain in the left side if my abdomen, bleeding whenever going to the toilet. Leg pain and tiredness /fatigue and a mouth ulcer
@@unicorn3241 thank you for the information. Was your fatigue severe? And did you have joint and muscle pain throughout? If so, how severe was it?
Nice amazing
Jokes on you cuz I have both!…Haha 😢
Up
I was normal until i aquired uc because my girlfriend did an incorect colonoscopy.
