Allergic Rhinitis (Hay Fever) affects about 30 million people in America and has increased in prevalence over the last 25 years. Allergy medications have dominated the shelves in many pharmacies as a result of the increasing brands of antihistamines, nasal sprays and decongestants. Despite the plethora of remedies, both over the counter (OTC) and by prescription, many people continue to suffer from chronic nasal congestion and post-nasal drainage.
Twenty five years ago intranasal steroids (INS) were ushered into the market as a novel approach to treating allergic rhinitis. Nasalid (flunisolide) led the way. Vancenase (Beclomethasone) and Nasacort (Triamcinolone) nasal sprays soon followed. These sprays offered a class of topically active steroids that, unlike previous nasal steroid sprays, had minimal systemic impact. This means the majority of the spray worked on the inner surface of the nose with very little absorption into blood vessels (reducing...
Bloody stools often are a sign of an injury or disorder in the digestive tract. Your doctor may use the term "melena" to describe black, tarry, and foul-smelling stools or "hematochezia" to describe red- or maroon-colored stools.
Stools - bloody; Hematochezia; Melena; Stools - black or tarry
Blood in the stool may come from anywhere along your digestive tract, from mouth to anus. It may be present in such small amounts that you cannot actually see it, and it is only detectable by a fecal occult blood test.
When there is enough blood to change the appearance of your stools, the doctor will want to know the exact color to help find the site of bleeding. To make a diagnosis, your doctor may use endoscopy or special x-ray studies.
Black stool usually means that the blood is coming from the upper part of the gastrointestinal (GI) tract. This includes the esophagus, stomach, and the first part of the small i...
Definition Stools that float are usually due to poor absorption ( malabsorption ) of nutrients or excessive gas (flatus). Alternative Names Floating stools Considerations Floating stools are seen in a variety of different situations. Most are diet-related, or occur during a gastrointestinal infection. A change in diet can lead to an increase in the amount of gas produced by the bacteria found in the (healthy) gastrointestinal tract. Acute gastrointestinal (GI) infections also can result in increased gas in the intestines, due to rapid movement of food through the GI tract. One wrong idea is that floating stools are caused by an increase in the fat content of the stool. In fact, it is increased gas in the stool that makes it less dense and allows it to float. Increased levels of nutrients in the stool that have not been absorbed by the GI tract supply the normal bacteria that live in the gut. These bacteria, in turn, produce more gas. This results in more gas-rich stools that float. Common Cause...
