Blood pH: normal values ​​and how to measure

  Fact-checking   Autentic   DMCA   Report

The blood pH must be between 7.35 and 7.45, which is considered a slightly alkaline pH. The alteration of these values ​​is a serious situation that puts health at risk, including the probabilities of death.

Acidosis is considered when the blood has values ​​between 6.85 and 7.35, while alkalosis is considered when the blood pH is between 7.45 and 7.95. Values ​​less than 6.9 or greater than 7.8 can produce the death of a person.

The maintenance of the blood within its normal values ​​is important to maintain the quality of the cells that are irrigated by the blood. In this way, when the blood is within its normal values, the cells are healthy, although when it is at more acidic or basic values, the cells die more quickly, producing illnesses and complications.



How do you measure the pH of blood?

The only way to measure blood pH is by means of an analysis of blood called arterial blood gas, which is performed when the person is hospitalized in the ICU or ICU. This analysis is carried out by obtaining a sample of blood, and its result by sampling the pH of the blood, the bicarbonate, and the PCO2. Know more about arterial blood gas and its normal values.

Symptoms of acidosis and alkalosis

When the pH is above its normal values, it receives the name of metabolic alkalosis, and when it is below, it receives the name of metabolic acidosis. The symptoms that help to identify these changes in blood are:

Alkalosis (pH by above normal)

In all cases, metabolic alkalosis produces symptoms and, in most cases, it is the symptoms of illness that produce alkalosis. Symptoms such as muscle spasms, weakness, headache, mental confusion, seas and convulsions can also arise, caused mainly by electrolyte alterations such as potassium, calcium and sodium.



Acidosis (pH by normal understatement)

The acidic pH produces symptoms such as shortness of breath, palpitations, vomiting, drowsiness, disorientation and even, it can be put at risk for life, in case it gets worse and you don’t receive treatment to normalize the pH.

What can change blood pH?

The blood pH can decrease in such a way that it becomes slightly acidic, which could lead to situations such as uncontrolled diabetes, malnutrition, where there is consumption of body proteins; chronic bronchitis, excessive use of acetylsalicylic acid, and extreme breathing difficulties.

Likewise, the pH of the blood may increase slightly, causing the blood to be more basic, in case of frequent and uncontrolled vomiting and diarrhea, hyperaldosteronism, severe respiratory problems, fever or kidney failure.

When the blood suffers some alteration, the body tries to correct this alteration by means of compensatory mechanisms, but in all cases it is not enough. In the most serious cases, it may be necessary to be admitted to the hospital. However, before this happens, the body tries to normalize the pH of the measurement, with the objective of maintaining the blood at neutral values.

Foods that acidify or alkalize blood

But more acid if you find the levels of the body, the greater the effort you will need to maintain the blood at a neutral pH, and greater the risks of developing diseases, so, while the blood is within its normal values, it is possible to maintain it in more basic values, by means of food.

Foods that acidify the medium

Some foods that acidify the medium, so that the body works more to maintain the blood pH neutral with the frijol, huevos, harinas in general, cacao, alcohol, acetunas, cheeses, meats, fish, maizena, sugar, milk, coffee, refreshments, pepper and sauerkraut.

In this way, in order to work less with the body and reduce the risk of diseases, it is recommended to reduce the consumption of these foods.

Foods that alkalize the medium

The foods that help to alkalize the medium and facilitate the body to maintain the blood pH within its normal values ​​are those rich in potassium, magnesium and/or calcium, such as avocado, melon, grapefruit, grape, orange, lemon , maize, dried higo, dark green vegetables, avena, albaricoque, palm datilera, apio y pasas, for example.

In this way, in addition to increasing the consumption of these foods, it helps your body to remain healthy, preventing diseases.
