Every piece of food that goes into your mouth passes through your digestive system, which includes esophagus, stomach, small intestine, large intestine, and rectum. Colon is final stop for digesting food before it exits body as fecal waste. And here, colon absorbs any remaining nutrients, and electrolytes. But while you might think of your colon as nothing more than continuous waste tunnel, it actually consists of four parts: ascending colon, transverse colon, descending colon, and sigmoid colon. Most people do give much think to innermost functions of their colon, and in most cases, they prefer not to. But if you have diverticulitis, getting to know your sigmoid colon may provide better understanding of your condition. Typically, with problems in digestive tract, doctor may recommend colonoscopy to view colon and help diagnose digestive conditions. But for good reason, your doctor wo put your body through when youre dealing with diverticulitis pain, at least not at first. Rather, youll complete other testing such as blood and urine tests to rule out problems with your kidneys or liver, and your doctor may perform MRI or CT scan of abdominal area to check for diverticulitis. Depending on findings, treatment may include oral or intravenous antibiotics, pain medication, or your doctor might bring up topic of surgery. Although your doctor may initially delay colonoscopy, youre not completely off hook. If youre diagnosed with diverticulitis, you will need colonoscopy about six weeks after you recover to rule out other possible causes of symptoms. Eat more fiber. Low - Fiber Diet Increases Risk Of Developing Diverticula, Which, Of Course, Can Lead To Diverticulitis. More Fiber You Eat, Easier Itll Be For Stools To Pass Through Colon, Thus Alleviating Pressure And Strain. Ideally, you should eat 21 and 38 grams of fiber per day. If this feels like too supplement with fiber tablets. Limit red meat. You dont have to give cheeseburgers and steaks entirely, but you should aim to eat red meat in moderation. Prepare few meatless meals each week and make conscious effort to snack on more vegetables during day. Quite simply, by eating more and less meat, you can dramatically reduce your risk of developing diverticulitis, says Bulsiewicz. Get moving. Exercise can feel like chore, and you might use any and every excuse to avoid physical activity. No one is suggesting spending hours in gym every day. But you should aim for at least 30 minutes of moderate - intensity exercise five days week. Take probiotic. Probiotics which are bacteria may also help your digestive tract run smoothly. Good sources probiotics include yogurt and sauerkraut; or taking probiotic supplement. Drink plenty of fluids. Proper hydration helps keep stool soft and prevents straining, thus alleviating pressure on sigmoid colon.

Structure

Intestinal Wall Is Made Up Of Multiple Layers. 4 layers of large intestine lumen outward are mucosa, submucosa, muscular layer, and serosa. Muscular Layer Is Made Up Of 2 Layers Of Smooth Muscle, Inner, Circular Layer, And Outer, Longitudinal Layer. These layers contribute to motility of large intestine. There are 2 types motility present in colon, haustral contraction and mass movement. Haustra are saccules in colon that it its segmented appearance. Haustral contraction is activated by presence of chyme and serves to move food slowly to next haustra, along with mixing chyme to help with water absorption. Mass movements are stronger and serve to move chyme to rectum quickly. Absorption of occurs by osmosis. Water diffuses response to osmotic gradient established by absorption of electrolytes. Sodium is actively absorbed colon by sodium channels. Potassium is either absorbed or secreted depending on concentration in lumen. Electrochemical Gradient Created By Active Absorption Of Sodium Allows For This. Chloride ions are exchanged for bicarbonate ions electrochemical gradient. Colon also play role in providing required vitamins through environment that is conducive for bacterial cultivation. Colon houses trillions of bacteria protect our gut and produce vitamins. Bacteria in colon produce substantial amounts vitamins by fermentation. Vitamin K and B vitamins, including biotin, produced by colonic bacteria. These vitamins are then absorbed into blood. When dietary intake of these vitamins is low in individual, colon plays significant role in minimizing vitamin disparity.

Function

Large Intestine Has 3 Primary Functions: Absorbing Water And Electrolytes, Producing And Absorbing Vitamins, And Forming And Propelling Feces Toward Rectum For Elimination. By time indigestible materials have reached most nutrients and up to 90 percentage of water has been absorbed by small intestine. Role Of Ascending Colon Is To Absorb Remaining Water And Other Key Nutrients From Indigestible Material, Solidifying It To Form Stool. Descending colon stores that will eventually empty into rectum. Sigmoid colon contracts to increase pressure inside colon, causing stool to move into rectum. Rectum hold feces elimination by defecation.
