Gastric Juice and Intestinal Juice

How much gastric juice and intestinal juice you produce per day

The advice is always given to drink between 1.5 and 2 liters per day. This water is necessary to keep your body well on track. However, the coffee, tea and water you drink is not the only moisture that gets into your digestive tract. Your body also produces gastric juice and intestinal juice in all kinds of forms. But how much sugar juice and intestine juice do you actually produce on average per day?

In short, your gastrointestinal tract runs from mouth to butt. During that process, a lot happens with the food and drinks that you consume. It is, among other things, digested, nutrients are absorbed and waste materials are eventually excreted via the feces. Below is an overview of the (most important) components of the gastrointestinal tract.

Mouth and esophagus

Your food is chewed in your mouth. Because the food is chopped into small pieces, the saliva can work on a larger surface. In the saliva are enzymes such as amylase. These are the first step in the digestion of sugars. The food is then pushed into the esophagus. The esophagus is only a transport tube. There is not much else happening.


Then the food arrives in the stomach. It contains gastric juice that is very acidic, hence the name stomach acid. Because of this acid environment bacteria and other micro-organisms are killed. This includes many enzymes that also contribute to the digestion of your food.

Small intestine

The small intestine is many meters long and consists of three parts: the duodenum (the duodenum), the jejunum and the ileum. In the small intestine the largest part of the absorption of nutrients takes place. Every part of the small intestine absorbs other nutrients to a certain extent. The last piece of the ileum, for example, is the only vitamin B12 to absorb. A lot of moisture is also absorbed in the small intestine. Bile and digestive juices from the pancreas also end up in the small intestine.


The food then continues to the colon. It absorbs the last nutrients and also moisture. There are also a lot of bacteria in the colon. These also play an important role in digestion. Influenced by the bacteria, vitamin K is formed, which is then absorbed into the blood.

Anus and anus

The food remains pass through to the rectum. The rectum is also just a transport tube. Ultimately, the food remains as stool leave your body.

How much gastric juice and bowel juice per day?

All day gastric juice and intestinal juice is produced. Each part of the intestine makes a different amount of moisture. In the gastrointestinal tract, most of the fluid is eventually taken up again so that not everything goes out with your feces. How much gastric juice and intestinal juice is produced exactly per day?

Disbalance and diarrhea

The colon has a large reserve to absorb fluid. For example, if you drink 3 liters a day, your colon can also take this extra liter. This fluid is eventually released from the body via the urine. As you can read, there is normally a good balance in the gastrointestinal tract: enough moisture is absorbed to ensure that there is little moisture in the stool. However, an imbalance may develop in certain diseases; there is not enough moisture absorbed in comparison with the supply. This causes too much fluid in the stool and diarrhea. This occurs, for example, in diseases that affect the intestinal wall, such as Crohn’s disease. Certain bacteria and viruses can also disrupt the balance.
