Respiratory Acidosis

What is respiratory acidosis? Respiratory acidosis is a condition that occurs when the lungs can’t remove enough of the carbon dioxide (CO2) produced by the body. Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. Normally, the body is able to balance the ions that control acidity. This balance is measured on a pH scale from 0 to 14. Acidosis occurs when the pH of the blood falls below 7.35 (normal blood pH is between 7.35 and 7.45). Respiratory acidosis is typically caused by an underlying disease or condition. This is also called respiratory failure or ventilatory failure. Normally, the lungs take in oxygen and exhale CO2. Oxygen passes from the lungs into the blood. CO2 passes from the blood into the lungs. However, sometimes the lungs can’t remove enough CO2. This may be due to a decrease in respiratory rate or decrease in air movement due to an underlying condition such as: There are two forms of respiratory acidosis: acute and chronic. Acute respiratory acidosis occurs quickly. It’s a medical emergency. Left untreated, symptoms will get progressively worse. It can become life-threatening. Chronic respiratory acidosis develops Continue reading >>

    So, as I have been reading more and more about Ketogenic diets, the topic of Ketoacidosis repeatedly comes up. From what I understand, a prolonged Ketogenic diet would eventually lead to Ketoacidosis. Obviously, this is not the case as people have been doing Keto for extended periods of time and do not exhibit any of the harmful effects associated with Ketoacidosis. Does anyone have any good sources explaining this?

    can you link to any credible sources that say benign dietary ketosis would eventually lead to ketoacidosis?

    Here is an article documenting this in a woman on Keto diet for 4+ years. It was published by the New England Journal of Medicine.
    http://www.nejm.org/doi/full/10.1056/NEJMc052709
    It mentions that the woman may have had a pre-disposition to ketoacidosis. However, the pathways it mentions for ketoacidosis to occur suggest that it would be more likely in a starvation diet. It did not indicate that the woman was engaged in a low calorie keto diet.
    Another article documenting a similar case, but with the subject on the diet for approximately 3 weeks.
