The digestive system is made up of several organs that all work together so that the body can get the energy it requires to go about its daily tasks. The initial way the gastrointestinal (GI) system does this is by breaking down the food we eat into smaller and smaller pieces so that the body can use the energy from the food to help repair and build new cells. The pathway that the food takes to go through the body is called the gastrointestinal tract. The GI tract is a series of organs that begins in the mouth and goes all the way to the anus, which, in adults, is about thirty feet long and takes anywhere from twenty four to seventy two hours, depending on the individuals digestive factors, for food to travel through. The first leg of …show more content…
The treatment for constipation is largely based on the patient’s symptoms. The first, and easiest treatment, is having the correct diet, high in fiber, high in fluid intake, and increasing exercise is important, the proper diet will be discussed further in the nutrition section. Another thing that helps constipation is trying to start a regular schedule to have bowel movements. Once the body realizes that it is on a schedule, it adapts and, surprisingly, the patient will most likely feel the need to defecate at approximately the same time each day. Along with the schedule, it is important that the patient does not ignore the urge to have a bowel …show more content…
My patient’s potassium level was within normal limits, but her chloride and sodium levels were low. The normal range for chloride is 99-110 mmol/L, over three days, her levels were 98, 94, and 93 mmol/L. One reason for this may be from the recent dehydration, or possibly because she is taking two laxatives while she was in the hospital. Some expected signs and symptoms of a low chloride level are loose frequent stools, and tremors, both of which my patient exhibited during the clinical day (Dunning & Fischbach, 2009). Her sodium level was low as well. The normal range for sodium is 135-145 mEq/L, my patient had two values of 131, and 132 mEq/L over three days, which is also due to the dehydration and recently recovering from a fever. Some signs and symptoms that go along with having a low sodium level are confusion, tremors, and increased heart rate (Dunning & Fischbach,
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Ondansetron showed a clinically effectiveness in changing the stool form and decrease the urgency of deification, but no improvement in term of pain. Also, it showed a well tolerated side effect that could be decrease by dose reduction. So, for patients with IBS-D who complain from stool urgency, ondansetron will be a great treatment options for them.
Each person with the disease must adjust in their own way, but they must adjust. Even though there is no cure at this time, research is ongoing and promises to improve the health and quality of life for those with Crohn’s disease.
The digestive system is interesting, complex and truly important to our daily lives. Without the digestive system energy and nutrients vital to the body could never reach body cells and a person wouldn't be able to do all the things they like to do, such as study, play sports, and hang out with friends. The body uses various organs and chemicals to break down food. The breakdown of food he... ...
This disease affects the muscles in the intestines. It can cause gas, abdominal pain, diarrhea and constipation. It usually does not lead to further diseases. Most people can control the symptoms through diet, stress management and medication.
If symptoms are mild then they may not require specific treatment as the symptoms can clear up by itself. Certain foods may trigger diarrhoea and bloating. They should be given lifestyle and dietary advice. They should be advised to drink plenty of fluids and eat small amounts of food throughout the day. Patients should avoid high fibre foods such as bran, beans and nuts. They may also limit their intake of milk products if they are lactose intolerant. Finally they should avoi...
A person who has IBS can lead a normal life. One would think that with continual diarrhea that a person with IBS would lose weight, be malnourished, or that they would develop more serious digestive problems. However, these are very rare. Only in a very small number of cases does IBS become so disabling that it can interfere with a person’s normal activities. But some people withdraw from activities because the diarrhea or constipation bothers them. In such cases, doctors may recommend mental health counseling.
The digestive system, in organisms like the mink and human, is supposed to break down the food being eaten to transfer into energy. This energy helps other functions of the body that would in turn keep it alive. The digestive system includes organs such as the stomach, intestines, liver, etc. Digestion starts at the mouth, though.

Irritable bowel syndrome (IBS) is a common disorder of the intestines that leads to crampy pain, gassiness, Bloating, and changes in bowel habits. Some people with IBS have constipation. Others have diarrhea or frequent loose stools, often with an urgent need to move the bowels and some people experience both. Sometimes the person with IBS has a crampy urge to move the bowels but cannot do so.
Imagine, being born with your intestines hanging out of your belly. Sounds painful and uncomfortable right? "About 2,000 babies are born with gastroschisis each year in the United States" (Gastroschisis. (n.d.). Retrieved May 9, 2014, from http://www.cardinalglennon.com/fetalcareinstitute/conditions/AbdomenIntestines/Pages/Gastroschisis.aspx). Thats about 1 in every 5,000 babies born, not rare, but fairly uncommon for it to be seen in children. Most are born prematurely, but are often delivered naturally without any surgery on the mother.
In rare cases when a patient does not respond to drug treatment or diet and lifestyle changes, surgery may be necessary. Doctors will remove part or all of the colon in attempt to stop the condition. Surgeries for UC are generally successful but significantly decrease quality of life because the patient has to deal with frequent stools due to the absence of a colon.
The human digestion system is very complex. It starts with the mouth, salivary glands, pharynx, esophagus, stomach, liver, pancreas, gallbladder, small intestine, large intestine, then ends/exits with the anus. Each step is essential to the whole system. For example, the mouth chews food and mixes it with saliva produced by the salivary glands, and then the pharynx swallows chewed food mixed with saliva, this is followed by the food traveling through the esophagus to the stomach where the food gets a bath and mixes with acids and enzymes. After the stomach, the liver, pancreas, and gallbladder produce, stores, and releases bile and bicarbonates. Bile is produced in the liver and aids in digestion and absorption of fat while the gallbladder stores bile and releases it into the small intestine when needed. Following the process into the small intestine, this is where nutrients will be absorbed into the blood or lymph (most digestion occurs here). Next is the large intestine this is where water and some vitamins and minerals are absorbed. Finally, it is the end of the road, the anus. At...
These wastes are derived from the liquid and food that the individual had consumed. In cases of compromised kidney function, the kidneys are no longer able to remove or filter wastes in the normal way. This means that wastes are left to accumulate in the bloodstream. When this scenario takes hold, it can negatively impact the patient 's electrolytes, therefore, positive action has to be taken to optimize the situation. When patients follow a renal diet it can help to slow down the advancement of total kidney failure, and ameliorate kidney function. Along with chloride and potassium, sodium represents one of the body 's main three electrolytes. The latter manipulate the fluids with enter and leave the body’s cells and tissues. Therefore, patients with renal disease must monitor their intake of electrolytes. Keeping a daily food dairy is essential (Nephcure), and will be of great benefit to the dietitian who can pinpoint certain details.
The digestive system is very responsible for taking the whole food that people eat and turns them into energy and nutrients to allow the body to function, grow, and fix itself. The six primary processes of this system are ingestion of food, secretion of fluids and digestive enzymes, mixing and movement of food and waste throughout the body, digestion of food into small pieces, absorbing the nutrients, and the elimination of wastes. Ingestion is the first function of the digestive system, which is also known as the intake of food. The mouth is the reasoning for this process because through the mouth is the way food enters the body. The stomach and the mouth store food until your stomach is ready to digest the food that was just eaten. The reason why people can only eat a few times a day is because your body can only allow a certain amount of food depending on your body weight and type, and it cannot ingest more food than it can process at one time. The next step in Secretion, this happens in the course of the day. The digestive system secretes about 7 liters of fluid daily, but these fluids include saliva, mucus, hydrochloric acid, enzymes, and bile...
