11.) Malabsorption syndrome includes a variety of disorders in which the intestine is unable to properly absorb specific nutrients into the bloodstream (Cafasso & Kerr, 2015). This can hinder the absorption of various macronutrients such as proteins, carbohydrates, and fats, macronutrients (vitamins and minerals), or even both (Cafasso & Kerr, 2015). Moreover, malabsorption syndrome happens when there is something preventing the bowel from taking in important fluids and nutrients. It can be…

due to vast advances in technology and research on pancreatic cancer. Pathophysiology The pancreas is a small, flat gland that can secrete both hormones such as insulin and enzymes that aid in digestion and is closely associated with the stomach, duodenum and the spleen (Huntsman, 2015; Huether, 2012). Its close relationship with the digestive process makes it an important organ. It is supplied with blood through the celiac and mesenteric arteries and exits out the portal vein (Huether,2012).…

rise in popularity. The mechanisms of bone loss after bariatric surgery are currently unknown but are likely multifactorial. Early explanations of bariatric surgery–induced bone loss centered on calcium and vitamin D malabsorption. RYGB bypasses the duodenum and proximal jejunum, the primary sites of calcium absorption, and may lead to malabsorption of fat soluble vitamins such as vitamin D.…

umbilical. When the chyme enters the duodenum, two hormones will be produced: secretin and cholecytokin. These hormones will inhibit gastric secretion and gastric motility and therefore the chyme will mix with the bile and pancreatic juices (Ross and Wilson, 2014). The small intestine is lined with epithelial tissues and even closer are villi and micro villi, which create a large surface area for the small intestine which allow it to absorb nutrients. The duodenum receives bile from the liver…

Cestodes have a scolex with two longitudinal bothria. There are hooks present and they also have genital pores that are lateral or medial, which depends on the species. They also have numerous testes. The life cycle of this parasite involves a crustacean as the first intermediate host and a fish as the second intermediate host. The size of the species varies widely and the largest known measure more than 40 meters long. Each segment has four to fourteen complete sets of genitalia. The scolex of…

and also can cause internal bleeding. There are two main types of peptic ulcers; they are gastric ulcers that are formed on the lining of the stomach and duodenal ulcers that are found on the lining of the upper part of the small intestine the duodenum (Crowe, 2017). Some of the risk factors that can cause peptic ulcers are increased…

The deficiency of iron is related to decreased gastric and decreased absorptive capacity of the duodenum. The mechanism for developing osteomalacia is incompletely described, although the duodenum is a major site for calcium absorption (Stenson, 1999). Food items for a patient with Peptic Ulcer Permitted foods-Wheat chapattis, rice, maize, jowar, bajra or ragi, cereal of wheat, rice, oatmeal or maize, rice cooked, pulses and beans, vegetable soups, cooked vegetables, potato, sweet potato, meat,…

1.4.9 Kinetics and metabolism Polycyclic Aromatic Hydrocarbons are lipophilic compounds that are readily absorbed from the lungs following inhalation, the gastrointestinal (GI) tract following ingestion and the skin following dermal exposure (ASTDR, 1995). In humans, it was reported that B(a)P measured in the lungs following inhalation of soot particles was much lower than expected. This may be due to the ability of the pulmonary epithelial cells to metabolise B(a)P thereby facilitating its…

As a result of the above recommendations and in order to improve fertility and pregnancy outcomes, many women of reproductive age have been advised or have been themselves seeking to lose weight via numerous interventions. Some of these interventions include the conventional method of diet and exercise. Indeed, a low-fat, reduced calorie diet is the best studied weight loss, dietary approach and is the most commonly recommended dietary method by governing health authorities. Such diets are…

and biting breaks down carbohydrates physically and chemically. The enzyme salivary amylase combines with food. When the food enters the stomach hydrochloric acid present causes hydrolysis of sucrose to glucose and fructose. The food passes to the duodenum where pancreatic amylase is secreted and has optimum PH, so most digestion of carbohydrates takes place in the small intestine. There are enzymes present in the brush border which converts disaccharides into monosaccharides see they can be…
