SIBO is the overgrowth of large intestine bacteria in the small intestine. There are many causes: malfunction of the ileocecal valve, bariatric surgery, proton pump inhibitors among others. The abundant bacteria in the small intestine compete with the small intestine for sugars and carbohydrates and produce large amounts of gas and malnutrition. The gas can emanate from the mouth or skin.
Constipation is defined as having a bowel movement fewer than three times a day (by some experts), one time a day or three times a week by others. The feces are usually hard, small, dry, and difficult to evacuate. The polluted environment in the colon may be killing off the friendly bacteria and permitting the proliferation of the harmful toxic bacteria. An incredibly strong body odor or bad breath is noticeable, even with an impeccable hygiene.
c. Anal Fissures
An anal fissure is unnatural crack, ulcer, cut, split or tear in the lining of the anal canal. The anal canal is the last part of the rectum before the anus. There is a possibility of mild leakage of gas or stool (anal incontinence).
d. Anal Fistula
An anal fistula is an abnormal tiny channel from the anal canal that is connected with the remains of an old anal abscess to a hole in the skin near the opening of the anus. Body wastes traveling through the anal canal are diverted through this small tube and out to the surface of the skin, causing itching, irritation, and leaking a pus or a foul-smelling discharge from the area.
e. Leaky Gut Syndrome
Leaky gut syndrome is defined as hyper-permeable intestinal lining. That means that spaces are formed between the cells of the gut wall, allowing bacteria, toxins, undigested food, and waste leak through. LGS can trigger allergic reactions in a person. An individual who has severe LGS will leak feces back into the blood stream and the body has to excrete it through breath and sweat.
f. Crohn's Disease;
Crohn's disease is a chronic, recurrent inflammatory disease. The swelling extends deep into all layers of the affected organ. Crohn's can affect any part of the gastrointestinal tract from mouth to anus, but mostly the illeum located in the lower part of the small intestine. The inflammation can lead to pain and can make the intestines empty frequently.
g. Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disease limited to the colon and the anus. Ulcerative colitis causes swelling and ulcers in the top layer of the lining of the large intestine.
h. Irritable Bowel Syndrome
Irritable Bowel syndrome. IBS affects the colon. It has many names: functional bowel syndrome, irritable colon, spastic bowel and spastic colon. In this case the intestines contract too hard or not hard enough. The nerves and muscles in the bowel appear to be extra sensitive, and cause food to move too fast or too slow through the intestines. The symptoms are abdominal pain, cramping, bloating, gas, diarrhea, and/or constipation.
i. Ileocecal Valve Syndrome
Ileocecal valve syndrome. The sphincter prevents reflux of bacteria from the colon into the small bowel. Sometimes it get stuck open allowing the fecal material to go back into the small intestine, or on the contrary, it can get blocked not allowing the fecal waste to go to the colon. If the valve does not work properly, it can lead to toxicity and bacteria overgrowth.
j. Fecal Incontinence
Fecal incontinence is when the body cannot control the bowels. When a person has the urge to have a bowel movement, he may not be able to hold it, or stool may start leaking from the rectum unpredictably, sometimes while passing gas. It can be due to muscle damage, nerve damage, pelvic floor dysfunction, diarrhea, loss of storage capacity or constipation.
k. Intestinal Obstruction
Intestinal Obstruction can be a partial or complete blockage of the bowel , as result intestinal contents fail to pass through. It can be mechanical or non-mechanical. Mechanical obstruction occurs when movement of material through the intestines is physically blocked like in twisted intestines, tumors, hernia, impacted feces, gallstones and others. If the blood supply in the intestine stops , the tissue can get infection and gangrened. Depending where the obstruction is located a patient may vomit fecal contents with resultant fecal breath odor.
