Introduction
The gastrointestinal tract (GI) comprises of the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and the anus. Also, digestion process start from the mouth; the ingestion of food stimulate the salivary secretion (mouth), the food is chewed before its passage through the esophagus down to the stomach where mechanical and chemical digestion takes place. Pepsinogen from the chief cells helps with the digestion of protein, amylase from the saliva and pancreatic fluid helps with the digestion of carbohydrate, and a pancreatic enzyme known as lipase helps with fat digestion, but the protein digestion takes a longer time. Limited absorption takes place in the stomach, but major absorptions takes place in the small and large intestine and the waste product excreted through the rectum via anus at a convenient place and time.
The purpose of the discussion is to describe the pathophysiology of gastric acid stimulation and production. Including an explanation of the gastric stimulation and production changes with gastroesophageal reflux disease (GERD), peptic ulcer disease (PUD), and gastritis. In addition, review behavior impact on the pathophysiology of GERD, PUD, and gastritis. However, the description of the diagnosis and treatment of the

    Proton pump inhibitors are common clinical drugs that are effective in treating acid-related diseases. They work by reducing the amount of acid produced by gastric glands in the mucous membrane in the stomach. The gastric proton pump resides in this gastric mucosa at the apical pole of the parietal cells. Under normal circumstances, approximately three liters of stomach acid is produced in a day under the regulation of the parasympathetic nervous system. The principle stimulant of acid secretion by the gastric proton pump is food intake, which acts by releasing gastrin.…

    If a patient has Gastro-esophageal Reflux Disease (GERD) the lower esophageal sphincter does not close properly. Because it does not close properly it allows the acidic stomach contents to flow backwards into the esophagus (Rubin et al 1990). If left untreated it could potentially lead to some esophageal problems which can include ulcers, bleeding, narrowing, and Barrett’s esophagus (Rubin et al 1990). Some of the factors that contribute to Gastro-esophageal Reflex Disease are hiatal hernia, obesity, Zollinger-Ellison syndrome, Hypercalcemia, Scleroderma, and systemic…

    The digestive system is a series of hollow organs that form a long tube that extends from the mouth, through the abdominal cavity, and ends at the anus. It consists of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, and accessory organs such as the salivary glands, liver, gallbladder and pancreas. The digestive tract contains food from the time it is consumed until it is either absorbed by the body or eliminated; muscular contractions of the digestive tract help to propel the food through all sections of the digestive system, and also work to help break the food into smaller particles. Several of the organs of the digestive system, and most of the accessory organs secrete various enzymes that help to break food particles down chemically into molecules that the body can use (Tortora and Derrickson 2014).…

Food is ingested in the mouth and moves along the digestive tract to the anus where waste is excreted. Along the digestive tract, food is digested and broken down into smaller food components that can be absorbed and utilized by the body. Nerves, blood, bacteria and the organs work together to complete digestion task.…

Many of the presenting symptoms may appear similar in nature. However, upon exploration of the historical details, an accurate diagnosis can be concluded. This paper will review the pathophysiology of normal gastric acid stimulation and production and the related alterations that occur with GERD, PUD, and gastritis. Additionally, the behavioral factor will be examined to gain a better understanding of its contribution to pathophysiology, diagnosis, and treatment.…

    3. Explain the concept of a negative feedback mechanism as it relates to gastric acid secretion. The cycle of this negative feedback mechanism starts when food entering the stomach triggers the release of gastrin from the cells of the stomach wall. Gastrin tells the stomach glands to secrete the elements of hydrochloric acid, thus increasing the pH of the environment to 1.5. Once an optimal pH of 1.5 is reached, the cycle reverses.…

    The regulation of acid and pepsin secretion is associated with a balance of chemo-transmitters delivered to the gastric mucosa by pathways that facilitate stimulation and inhibition. The physiologic stimulation of acid secretion is divided into the cephalic, gastric, and intestinal. The main component of gastric secretion is HCL which is a product of the parietal cells. The parietal cells are epithelial cells that secrete HCL and essential factors. Parietal cells are located in the gastric glands in the lining of the fundus and in the body of the stomach.…
