Irritable Bowel Syndrome, Fiber and Your Diet

The consensus among medical professionals and nutrition specialists is that eating a healthy, balanced diet and drinking at least eight glasses of water a day can help reduce the symptoms of irritable bowel syndrome. More important is the need to view the dietary habits of people suffering from IBS in the broader context of their general lifestyle, emotional state and other contributory factors.
In order to eliminate foods that cause "flare-ups " from an individual 's irritable bowel syndrome diet, the patient is asked to keep a food diary and note any particular items that appear to aggravate the condition. The physician may then refer the findings to a registered dietitian who will recommend appropriate changes to the IBS diet, tailored to the individual 's dietary requirements.
Often, all the patient has to do is to make a few simple food substitutions. For example, if a patient appears to be intolerant to the lactose content of certain dairy products (milk, in particular), a reduction in lactose intake coupled with the substitution of yogurt for milk may be all that is required.
Caution: Any "substitute " food should contain sufficient nutrients and the alternative choice should not deprive the IBS sufferer of a properly balanced diet.
If you have IBS, you should avoid:
  • large meals (over-eating can cause diarrhea and abdominal cramping)
  • excessive consumption of alcohol
  • caffeine
  • foods high in animal and vegetable fat (both fats stimulate strong colonic contractions and can cause intestinal cramping)
  • cabbage, beans and fruits that tend to cause bloating and gas.
How Useful is Dietary Fiber in IBS Treatments?
Although a high-fiber diet is recommended for the general treatment of gastrointestinal disorders, medical opinion is divided regarding its specific efficacy in IBS treatments. Those in favor contend that a high-fiber irritable bowel syndrome diet helps keep the colon slightly distended, which has the effect of reducing the occurrence of abdominal spasms and constipation.
Dietary fiber can be divided into two categories: soluble (dissolves in liquid) and insoluble. Soluble fiber is useful for controlling both diarrhea and constipation, whereas insoluble fiber tends to aggravate diarrhea. Most cereals, whole grain breads, vegetables and fruits contain insoluble fiber. Soluble fiber can be found in oat bran and a natural vegetable fiber called psyllium. Brand names for psyllium include Perdiem®, Fiberall® and Metamucil®.
Of course, the bottom line is that a lot depends upon your personal physician or dietician. Some advocate a fiber-rich irritable bowel syndrome diet, whereas others believe that dietary fiber merely aggravates the condition. Most physicians agree, however, that bulking agents can play a useful role in IBS treatments.
Controlled portions of cereals, whole grain breads and pasta, brown rice, fruits, beans and vegetables are generally recommended, but consult your dietitian to find out how much you should include in your daily meals.
Caution: Do not purchase an off-the-shelf fiber remedy before discussing it with your physician.

Nutrition & Cystic Fibrosis

Image
Cystic fibrosis is a genetic disorder that affects the body's exocrine glands, including the various mucus and sweat glands found throughout the body. Since cystic fibrosis is an inherited disease, most people with the disease are usually diagnosed by their first birthday. The most common problems due to cystic fibrosis are related to the lungs and the digestive system. In the lungs, the mucus produced by the various exocrine glands is abnormally thick, creating obstructions in the breathing passageways and, eventually, damage to the lungs. Furthermore, the thick mucus creates an ideal breeding ground for various bacteria and other organisms, which results in frequent lung infections, damage to the lungs and, ultimately, respiratory failure. Cystic fibrosis also affects the pancreas. The pancreas is responsible for producing various enzymes to aid in digestion, but in cystic fibrosis the pancreas is unable to excrete sufficient amounts of pancreatic enzymes to help digest foo

Pernicious Anemia: Vitamin B12 Deficiency

Image
Anemia  is a blood disorder in which the number of red blood cells or the amount of hemoglobin is lower than normal. With fewer red blood cells or hemoglobin, insufficient oxygen is delivered to the body 's cells. Pernicious anemia  is a type of anemia caused by a deficiency in vitamin B12. In pernicious anemia, the lack of vitamin B12 is due to the body 's inability to produce enough  intrinsic factor , a protein necessary for the absorption of vitamin B12. Pernicious anemia is a type of  megaloblastic anemia . Megaloblastic anemia is defined as, "a blood disorder characterized by anemia, with red blood cells that are larger than normal, usually resulting from a deficiency of folic acid or of vitamin B12 .  " (U.S. National Library of Medicine) Pernicious anemia by any other name . . . Pernicious anemia is known by a number of other names, including: macrocytic achylic anemia congenital pernicious anemia juvenile pernicious anemia vitamin B12 deficienc

Atresia of the Gastrointestinal Tract

Atresia , a closure or absence of a natural passage or orifice in the body, is a birth defect that can affect many parts of the body. In the case of gastrointestinal atresia, the passage of food through various digestive organs can be blocked, preventing the body from processing and extracting nutrients from food, and from excreting waste. Several types of gastrointestinal artresia have been identified. Esophageal Atresia The esophagus is the tube that connects the mouth and throat to the stomach. When you chew and swallow food, it travels down the esophagus for digestion in the stomach. Several types of esophageal atresia exist. In some cases, the esophagus narrows significantly, making it difficult for food to pass through. In most cases, however, the esophagus ends and does not connect to the stomach. Some babies with esophageal atresia may also have a tracheoesophageal fistula, or an abnormal connection between the esophagus and the trachea (windpipe). A baby may choke du
