Things You Should do Before a Colonoscopy Test Colonoscopy is an imaging test used to see the inside of your colon or rectum—parts of your large intestine. Doctors use this procedure to detect early signs of colorectal cancer growth help them diagnose unexplained changes in bowel movement, bleeding from the rectum or anus, abdominal pain, and weight loss. Before the test is done, the doctor

There are many kinds of digestive diseases ranging from mild conditions like indigestion and lactose intolerance to severe and life-threatening, such as cirrhosis and colon cancer. A digestive disease, also called gastrointestinal disease or digestive disorder, can occur in any part of the digestive system. The digestive system is comprised of the digestive tract, also called alimentary canal,

Gallstones and kidney stones are two major types of stones that develop in the body. However, they are not the same. They have differences in stone components and the organs where they develop are different, as well. Gallstones develop in the gallbladder - a small, pear-shaped structure located underneath the liver. The gallbladder stores bile, which is a fluid substance composed of water,

Does acid, specifically hydrochloric acid, in the stomach play a role in digestion? Yes. They play an important role in activating pepsin. Pepsinogen, which is the inactive form, becomes activated by stomach acid. Pepsin is an enzyme that breaks down proteins (e.g. pork and chicken) into smaller particles. This will make the enzymes in the small intestine work more effectively in breaking down

Many people think that having regular, daily bowel movement is important for good health. This is actually a misleading notion. Just like other bodily functions, what is considered to be "normal bowel movement" may be different from person to person. Some people may have bowel movement one or several times per day, but other healthy adults may have regular movement every other day. But how about

The last part of the digestive tract is the anal canal, which is about 2-3 centimeters long. The anus is actually the opening of the anal canal to the outside. The anal canal has two muscles: the internal anal sphincter and the external anal sphincter. The internal anal sphincter is made up of smooth muscles, which cannot be controlled or contracted voluntarily. On the other hand, the external

The Digestive Tract showing the esophagus and other digestive structures. The esophagus is about 25 centimeters (10 inches) long. It starts from the lower (inferior) portion of the pharynx (laryngopharynx) and ends at the upper (superior) portion of the stomach. The esophagus acts as a passageway for food and water going to the stomach and does not have anything to do with digestion or

You might have noticed that when you drink alcohol combined with high-fatty foods, you tend to to not get intoxicated easily. This can be explained with the physiological actions of the stomach. Some of the consumed alcohol is absorbed in the stomach. However, the surface area for absorption is much lesser in the stomach than in the small intestine. The small intestine is where most absorption

After eating a meal, it usually takes about 2 to 4 hours for the stomach to empty its contents. High fat foods take the longest time to empty from the stomach. On the other hand, carbohydrate rich foods tend to empty much faster. High protein foods empties slower than carbohydrates and a little bit much faster than fatty foods.

The large intestine is about 1.5 meters (5 feet) long. It starts from the end of the ileum (last part of the small intestine) and ends in the anus. The major parts/regions of the large intestine are the cecum, colon, rectum, and anal canal, which ends in an opening called the anus. The colon is further subdivided into several regions namely the ascending colon, transverse colon, descending colon

The human digestive tract is about 30 feet (9 meters) long when taken from a cadaver. However, the digestive tract, also called gastrointestinal (GI) tract or alimentary canal, is much shorter in live humans because the muscles in the walls of the tract are in a state of sustained contraction.

Vomiting or Emesis, When Should You be Concerned? Vomiting, also called throwing up or emesis, can be caused by a variety of health conditions. Nausea, on the other hand, is an uneasy feeling in the stomach together with an urge to vomit. Nausea and vomiting are not actual diseases.

Carbohydrates (carbs) are used by the body to make glucose, which is the fuel that gives energy. The body can immediately use this glucose, also called blood sugar, or it can store it in the liver and muscles to be used when needed. Carbs can be found in many foods, such as fruits; vegetables; breads, cereals, and other grains; milk and milk products; and foods that contain added sugars like

Difficulty swallowing, or dysphagia, is an upper digestive tract problem wherein a person has trouble taking in food and water. It is considered to more of a symptom than a disease because it can be caused by a variety of health problems. in some cases, jaw pain or pain the throat can cause trouble swallowing. Although anyone can have difficulty swallowing, it is more common in the elderly.

May 25, 2010 -- The US FDA has issued a warning that people who take certain acid reflux drugs called proton pump inhibitors (PPIs) have possible increased risk of fractures. Several epidemiological studies have reported an increased risk of fractures of the hip, wrist, and spine with PPI use. Some studies have shown that those at greatest risk for fractures those who used proton pump

The digestive system is composed of a very long tube called the digestive tract and accessory organs that aid in digestive processes. Accessory digestive organs and structures include the teeth, salivary glands (produce saliva), the liver and the pancreas. The process of digestion starts in the mouth. When we take in food, such as a piece of meat or bread, the teeth start to grind the food

The digestive tract is a part of a larger human body system called the digestive system. It is actually a very long hollow tube that starts from the mouth and ends in the anus. It measures about 9 meters when taken from a cadaver. However, in a live person, the tract measures much shorter because smooth muscles in the digestive tract wall are in a state of partial contraction. All of the

Reflux disease, also called gastroesophageal reflux (GER), is a digestive disorder that can occur in infants. This infantile reflux disease occurs when stomach contents including acid, back up or reflux into the esophagus—the tube connecting the mouth to the stomach. Normally, a ring of muscle between the esophagus and stomach called lower esophageal sphincter (LES) prevents reflux of stomach

There are several tests that doctors use to test for digestive disorders. In some cases, more than one test may be recommended to diagnose the digestive disorder or to rule out certain conditions.Most of these digestive tests give the doctor a view of the digestive tract and aids in better, more reliable diagnosis of the digestive problem. Patients who are asked to undergo certain tests should
