Lack of Digestive Enzymes
The enzymes are necessary to break down food so that the body can absorb it. When you don't have enough enzymes the undigested food ferments or putrefies, and putrefaction frequently results in poisonous ptomaines.
Hypochlorhydria or lack of hydrochloric acid. Adults loose about 13% of their stomach acid every 10 years which results in poor digestion. Undigested food becomes soil for bacteria which ferment and decompose. Not enough hydrochloric acid in the stomach means undigested food will go into the intestines, putrefy and emit foul gas which rises up and causes bad breath.
Acid reflux, commonly referred to as GERD, is a condition in which the liquid content of the stomach regurgitates into the esophagus. Episodes occur when the lower esophageal sphincter, which is normally closed in the resting state, becomes unable to close properly, allowing gastric odors and liquid to reflux.
Gastrojejunocolic fistula is an abnormal connection or passageway between the stomach, jejunum, and transverse colon. Gastrojejunocolic fistula is one of the serious complications of a stomach ulcer after a gastric resection with Billroth II reconstruction, which is regarded to be induced by an inadequate resection of the stomach. Fecal vomiting with resulting fecal breath odor may happen, but the most common primary complaint is diarrhea, accompanied by abdominal pain.
Gastroparesis is a motility disorder which means basically stomach paralysis. Symptoms can range from mild discomfort and bloating to nausea, pain, vomiting and malnourishment. In delayed gastric emptying condition food remain long in the upper gastrointestinal tract and decompose rather than being digested.
Hiatal hernia occurs when part of the stomach goes up into the chest cavity through an opening in the diaphragm. Diaphragm is a sheet of muscle. As the stomach bulges up into the opening, this condition allows gastric odors to reflux.
