Metabolic alkalosis, the dangers of consuming too much baking soda


The sodium bicarbonate It’s one of the ingredients that can not be missing in any home, since this is an extremely versatile tool, as it is used in cleaning the home, in gardening and of course in gastronomy.

But it turns out that it is precisely in the latter, gastronomy, where it has become more popular recently, this because a whole fashion has been created around its consumption, as there are those who claim that it can help alkalize the body, which apparently can be very healthy, however a excess of this can cause some problems, such as a metabolic alkalosis.

What is metabolic alkalosis?

It is known as metabolic alkalosis to one of the different types of disorders that exist in relation to acid-base balance of the body, in which there is a low concentration of circulating hydrogen ions, as well as an increase in bicarbonate levels, which in turn produces an increase in the pH of the blood plasma, which should have a range of 7.35 at 7.45.

When a metabolic alkalosis the pH in the arteries it is located at a level that exceeds 7.45, while the plasma bicarbonate level is registered with a level greater than 25 mmol / l.

Basically and to better understand the problem, a excess bicarbonate in the body It can make the body’s acidity drop considerably as to affect the balance of different functions, which undoubtedly puts our health at risk.


These are the different signals that can alert us to a metabolic alkalosis.

  • Irritation
  • Shaking
  • Muscle cramps
  • Muscle spasms

How is it diagnosed?

The first step to diagnose a metabolic alkalosis is to do an arterial blood gas, which is a test that is carried out by extracting a blood sample that is then introduced into a gasometer that must measure the pH, the arterial pressure of CO2 and the arterial pressure of O2 .

Other ways to reach a diagnosis is through a urine sample or even a blood chemistry analysis, this to measure in relation to the kidney, since metabolic alkalosis is due to the accumulation of baking soda of sodium in this organ, produced by factors such as Cushing or Bartther syndrome, diuretics, cystic fibrosis, vomiting or chlorodiarrhea, among others.

How is it treated?

Mainly you should go to your doctor and not self-medicate.

In the most serious cases, it could supply hydrochloric acid, although in general it is a matter of correcting its causes first, especially when it occurs due to excessive consumption of bicarbonate.
