What is the postprandial alkaline tide?

Ingestion of food leads to a rise in urinary pH. This phenomenon is commonly known as “postprandial alkaline tide” and is generally attributed to acid secretion in the stomach.

What is the cause of postprandial alkaline tide?

The postprandial alkaline tide occurs as a result of meal ingestion and the subsequent excretion and loss of gastric acids.

What is the purpose of alkaline tide?

The concept of an alkaline tide which compensates for gastric acid secretion suggests the possibility of indirect measurement of gastric acid secretion. This study was designed to determine whether postprandial changes in renal and respiratory function could be used to assess gastric secretion in healthy adults.

What fluid becomes basic during alkaline tide?

Acid–base balance Acid secretion in the stomach is accompanied by secretion of bicarbonate into the blood that makes the blood alkaline (the ‘alkaline tide’, see Ch. 3).

Is the Postprandial alkaline tide a real thing?

Postprandial alkaline tide: does it exist? The concept of an alkaline tide which compensates for gastric acid secretion suggests the possibility of indirect measurement of gastric acid secretion. This study was designed to determine whether postprandial changes in renal and respiratory function could be used to assess gastric secretion in he …

How long does alkaline tide last after a meal?

Alkaline tide. Postprandial (i.e., after a meal) alkaline tide lasts until the acids in food absorbed in the small intestine reunite with the bicarbonate that was produced when the food was in the stomach. Thus, alkaline tide is self-limited and normally lasts less than two hours.

Which is alkaline tide compensates for gastric acid secretion?

The concept of an alkaline tide which compensates for gastric acid secretion suggests the possibility of indirect measurement of gastric acid secretion. This study was designed to determine whether postprandial changes in renal and respiratory function could be used to assess gastric secretion in healthy adults.

What causes the alkaline tide in the body?

During gastric acid secretion, the equimolar secretion of base as HCO3− to the extracellular fluids (Fig. 6.3) can cause a metabolic alkalosis. This phenomenon has come to be known as the “alkaline tide.”
