What is acid rebound?
it is a condition resulting from taking too much antacid such that the stomach's ph rises to around 5 and to counter this the stomach lining cells secrete more hcl to counter this and dramatically reduce ph .
Gastrin?
DefinitionGastrin is the major hormone that regulates acid secretion in the stomach. It is produced by special cells in the stomach. Small amounts of gastrin may also be produced by the pancreas and possibly the intestines. When there is food in the stomach, gastrin is released into the blood. As stomach and intestinal acidity rises, gastrin production normally decreases.A laboratory test can be done to measure the amount of gastrin in the blood.How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.How to prepare for the testYour health care provider will instruct you, if necessary, to discontinue drugs that may interfere with the test.Drugs that can increase gastrin measurements include antacids, H2-blocking agents (such as cimetidine), and proton pump inhibitors (such as omeprazole).How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedYour doctor may order this test if you have signs or symptoms of a disorder associated with abnormal gastrin production.Normal ValuesNormal values are generally less than 100 pg/mL (picograms per milliliter).Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.What abnormal results meanToo much gastrin causes severe peptic ulcer disease. Greater-than-normal levels may also be due to:Chronic atrophic gastritisG-cell hyperplasia (overactivity of gastrin-producing cells in the stomach)Heliobacter pylori infection of the stomachUse of antacids or medicines that suppress stomach acidZollinger-Ellison syndrome, a gastrin-producing tumor that may develop in the stomach or pancreasWhat the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.Other risks associated with having blood drawn are slight but may include:Excessive bleedingFainting or feeling light-headedHematoma (blood accumulating under the skin)Infection (a slight risk any time the skin is broken)ReferencesJensen RT.

How do you spell acid refluy?
The term is spelled "acid reflux" (condition where stomach acid rises into and irritates the esopaghus).
Heart burn why can't feel in stomach?
Heart burn occurs when there is a build-up of acid in your stomach so the excess acid rises up your oesophagus which is in your chest. The stomach is used to acid but the oesophagus isn't so this is why it's felt here.
Gastrin - blood test?
DefinitionGastrin is the major hormone that controls the release of acid in your stomach. When there is food in the stomach, gastrin is released into the blood. As the acid level rises in your stomach and intestines, your body normally makes less gastrin.A laboratory test can be done to measure the amount of gastrin in the blood.How the test is performedA blood sample is needed. For information on how this is done, see: VenipunctureHow to prepare for the testCertain drugs may interfere with the results of this test. Your doctor will tell you if you need to stop taking any medicines. Do not stop taking any medicines before talking to your doctor.Drugs that can increase gastrin measurements include antacids, H2-blocking agents (such as cimetidine), and proton pump inhibitors (such as omeprazole).How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.Why the test is performedYour doctor may order this test if you have signs or symptoms of a disorder linked to abnormal amounts of gastrin. This includes peptic ulcer disease.Normal ValuesNormal values are generally less than 100 pg/mL (picograms per milliliter).Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.What abnormal results meanToo much gastrin causes severe peptic ulcer disease.

Why do stomach linings bush too when blushing?
Well, when you blush, there are chemicals produced in your body. Those chemicals are also produced in your stomach, which makes the lining turn red. Also, it is believed that the capillaries on the cheeks are connected to the stomach.
What cause you to have an upset stomach everyday?
what gives you an upset stomach is when you digest your food your food can rise up from the stomach from acid also known as gas building up in your stomach and so as it rises thats when you feel like you have and upset stomach.
How could the overuse of antacids inhibit protein digestion?
Antacids neautralize the normal stomach acid causing the pH to rise. When pH in the stomach rises above 4, Pepsin (an ezyme that works to break down protein into smaller pieces so they can later be broken down into amino acids) is decreased or stops. And without pepsin the protein isn't broken down thus inhibiting protein digestion.To understand this, you need to know that the digestion of proteins starts in the stomach with the help of digestive enzymes, mainly pepsin.Pepsin is secreted in an inactive precursor form, called pepsinogen (this is to prevent the stomach cells that secrete pepsin from undergoing autodigestion.)In the acidic environment of the stomach (pH
What happen when stomach acid and sodium bicarbonate come together in the small intestine?
When stomach acids, like HCl and pepsin, come in contact with sodium bicarbonate the pH level become more alkaline and less acidic. So the pH level rises.
Is all the food you eat used in the body during digestion?
Before answering this question you should be aware of the meaning of food and different types of food.The body needs Proteins, Carbohydrates and fat in order to grow. But this can not function without the breaking of food i.e Digestion. Digestion helps the food to be broken down into simple particles so that can enter the body through the flow of blood.In mammals, food enters the mouth, being chewed by teeth, with chemical processing beginning with chemicals in the saliva from the salivary glands. Then it travels down the esophagus into the stomach, where acid both kills most contaminating microorganisms and begins mechanical break down of some food (e.g., denaturation of protein), and chemical alteration of some. After some time (typically an hour or two in humans, 4-6 hours in dogs, somewhat shorter duration in house cats, ...), the results go through the small intestine, through the large intestine, and are excreted during defecation.Human digestion processUpper and Lower human gastrointestinal tractThe whole digestive system is around 9 meters long. In a healthy human adult this process can take between 24 and 72 hours.Phases of gastric secretionCephalic phase - This phase occurs before food enters the stomach and involves preparation of the body for eating and digestion. Sight and thought stimulate the cerebral cortex. Taste and smell stimulus is sent to the hypothalamus and medulla oblongata. After this it is routed through the vagus nerve and release of acetylcholine. Gastric secretion at this phase rises to 40% of maximum rate. Acidity in the stomach is not buffered by food at this point and thus acts to inhibit parietal (secretes acid) and G cell (secretes gastrin) activity via D cell secretion of somatostatin.Gastric phase - This phase takes 3 to 4 hours. It is stimulated by distention of the stomach, presence of food in stomach and decrease in pH. Distention activates long and myentric reflexes. This activates the release of acetylcholine which stimulates the release of more gastric juices. As protein enters the stomach, it binds to hydrogen ions, which lowers the pH of the stomach to around pH 1-3. Inhibition of gastrin and HCl secretion is lifted. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete HCl. HCl release is also triggered by acetylcholine and histamine.Intestinal phase - This phase has 2 parts, the excitatory and the inhibitory. Partially-digested food fills the duodenum. This triggers intestinal gastrin to be released. Enterogastric reflex inhibits vagal nuclei, activating sympathetic fibers causing the pyloric sphincter to tighten to prevent more food from entering, and inhibits local reflexes.There fore; All kinds of food must be digested.
What is one common application of thermal expansion?
A thermostat is a common application of a thermal expansion. It works as an indicator with an internal liquid that rises up if the temperature in the room also heats up.
Why would it be wrong to say homeostasis prevents internal change?
dude homeostasis is the process by which the internal environment of ur body stays constant for example in warm blooded animals when the body temp rises u start sweating and ur arterioles near the skin dilate so in this example homeostasis has occurred and there has been an internal change(dilation of the arterioles and production of swear) therefore homeostasis doesn't prevent internal change
