How would removal of 95 percent of the stomach to treat severe ulcers or cancer affect the digestion and absorption of food?
The stomach stores food and released small amounts regularly into the intestines for digestion. If the stomach was removed the patient must eat small amounts of food regularly. If they ate a normal sized meal it passes into the intestine and due to osmosis, a great deal of water moves into the intestines - 'dumping syndrome' which can cause nausea, diarrhoea, bloating, cramps, fatigue and dizziness. It would also affect blood sugar and could cause hypoglycaemia. So removal of the stomach makes digestion and absorption much more difficult.
The stomach lining cells also produce Intrinsic factor which is needed for the absorption of vitamin K. Therefore the patient may become deficient in vitamin K.
The job of the stomach is to break down proteins, mix and begin digestion. It is not involved in the absorption of food. If a person has a small stomach, they will loose weight but the stomach can stretch and enlarge.
What else can I help you with?
What is the pyloric valve located between?
The pyloric valve is located between the stomach and the small intestine. It regulates the flow of partially digested food (chyme) from the stomach into the small intestine for further digestion and absorption.
What is mixture of stomach fluids and food produced in the stomach by contracting stomach muscles?
The mixture of stomach fluids and food produced in the stomach by contracting stomach muscles is called chyme. Chyme is a semi-fluid mass that is created during the process of digestion and contains partially digested food along with gastric juices such as hydrochloric acid and enzymes. It moves from the stomach to the small intestine for further digestion and absorption of nutrients.
What are the organs of the digestion in order that the food passes through?
Food passes through the following organs in order during the process of digestion: mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Each organ plays a specific role in breaking down the food into nutrients that can be absorbed by the body.
After the food is processed in the stomach of a frog the food enters where?
After the food is processed in the stomach of a frog, the partially digested food moves into the small intestine for further digestion and absorption of nutrients.
What body system contains the organs?
The digestive system contains organs like the stomach, intestines, and liver that help with the digestion and absorption of nutrients from food.
What is the location where the majority of the digestion and absorption occurs?
Most of digestion occurs in the stomach and most absorption occurs in the small intestine.
Although the stomach is responsible for digestion very little occurs in it?
Absorption
Is the stomach the first site where absorption takes place?
No it is not, the stomach initiates protein digestion and denatures proteins. The intestines is the first site where absorption takes place.
Is The stomach is responsible for digestion and all absorption occurs there?
This is not true. Almost all absorption occurs in the small intestine. The stomach simply uses its enzymes to break down food into smaller and smaller molecules. The most mechanical digestion occurs in the stomach due to the constant churning motion.
What is the second stage of digestion?
The second stage of digestion occurs in the stomach. Here, food is mixed with stomach acid and digestive enzymes to further break down proteins and begin the process of nutrient absorption.
Where in the body is chemical digestion and absorption of nutrients completed?
Small and Large intestines
What organ does most digestion take place?
Most chemical digestion occurs in the stomach and absorption occur in the intestines in humans and many other animals.
Where does most digestion take place in the human body?
Most of the physical digestion takes place in the stomach, but the completion and absorption is done in the small intestine.
What occurs in the stomach although it is responsible for very little digestion?
Although the stomach is responsible for digestion, very little absorption happens in it. Instead, the stomach is more like a washing machine; it agitates foodstuffs. It stirs up ground up food (mechanical digestion from teeth / gums occurs in the mouth), with stomach acids in the stomach and bile salts from the gallbladder assisting in chemical digestion.
What is subtotal gastrectomy?
Subtotal gastrectomy is a surgical procedure that involves the removal of a significant portion of the stomach, typically to treat conditions such as stomach cancer, ulcers, or severe obesity. The remaining stomach is then reconnected to the small intestine to allow for digestion. This surgery can lead to changes in digestion and nutrient absorption, requiring patients to adjust their eating habits postoperatively. It is considered a more conservative approach than a total gastrectomy, where the entire stomach is removed.
Is the stomach above or below the intestine?
The stomach is above the intestine in the human body. Food travels from the stomach to the small intestine for further digestion and absorption of nutrients.
One medical procedure used to treat morbid obesity is the surgical removal of part of the stomach explain how this would affect chemical digestion?
Surgical removal of part of the stomach, such as in a sleeve gastrectomy, reduces the stomach's size, which limits its capacity to hold food. This can lead to changes in the secretion of gastric juices, including hydrochloric acid and digestive enzymes, thereby affecting the initial stages of chemical digestion. With less stomach volume, food is processed more quickly, which may reduce the overall time for chemical digestion and absorption of nutrients in the intestines. Additionally, the altered anatomy may impact hormone production that regulates hunger and metabolism.
