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 are the organs of the digestion in order that the food passes through?
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
Is the stomach responsible for absorption and digestion occurs in the small intestines?
The digestive system.
What are the functions of the major organs in the ailmentary canal?
Ingestion (mouth) Digestion (mouth, stomach, small intestine, liver/gallbladder) Absorption (small intestine) Elimination (large intestine)
What is the role of the stomach after the mouth is finishes to bolus the food?
After the mouth has finished chewing and forming the bolus, the stomach's role is to further break down the bolus through the process of mechanical and chemical digestion. The stomach muscles contract to mix and churn the bolus, while gastric acid and enzymes are secreted to help break down the food into a semi-liquid mixture called chyme. Additionally, the stomach helps control the rate at which chyme is released into the small intestine for further digestion and absorption.
What would happen if you didn't have you stomach?
You can survive without your stomach. There are three main digestive organs...the mouth, stomach and small intestines. Without the stomach, you may have to eat smaller amounts at each sitting or you may have to adjust what you put into the system, but your body can still do some basic digestion and the bulk of the absorption of the 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.
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 are the organs of the digestion in order that the food passes through?
The mechanical process of digestion is first, followed closely by chemical digestion. After that it is mostly chemical digestion, then absorption, and lastly elimination, or defecation.
What does the small intestine connect from and to?
The small intestine connects the stomach and the large intestine. It is the site of completion of digestion and most absorption.
Where does the absorption of nutrients occur in an cow?
Eighty percent of nutrient absorption occurs in the small intestine. The other 20% occurs in the stomach tissues.
What are the small intestines in the digestive system?
The small intestine plays a role in digestion of carbs and fats, but the primary role of the small intestine is the absorption of nutrients broken down by digestion. These include, the absorption of: Proteins (amino acids), Carbohydrates (monosaccharides), Fats (lipids), Vitamins and Minerals.
