Acid/base Disorders: Metabolic Acidosis

Are there clinical practice guidelines to inform decision-making? Does this patient have metabolic acidosis? Metabolic acidosis is generally defined by the presence of a low serum bicarbonate concentration (normal range 22-28 mEq/L), although occasionally states can exist where the serum bicarbonate is normal with an elevated anion gap (e.g., patients with a lactic acidosis who have received a bicarbonate infusion or patients on hemodialysis). In general, a metabolic acidosis is associated with a low urine pH but depending on the presence or absence of a respiratory alkalosis, this may also be normal or elevated. Thus, a patient can have an acidosis but not be acidemic. Metabolic acidoses occur when there is excess acid in the plasma. In the basal state, the body generates about 12,000 to 13,000 mmol of carbon dioxide (CO2), and 1-1.5 mmol per kilogram body weight of nonvolatile acid. The body has a large buffering capacity, with CO2-HCO3 as the major buffer system. The two major routes of acid excretion are the lungs (for CO2) and the kidneys (for nonvolatile acids) A metabolic acidosis can be caused by three major mechanisms: 1) increased acid production; 2) bicarbonate loss; an Continue reading >>

What Is Renal Failure: In this video, We will share information about what is renal failure - how to identify renal failure - symptoms of renal failure. Subscribe to our channel for more videos. Watch: (https://www.youtube.com/watch?v=ivQE7...) How to Identify Renal Failure Renal failure, also known as kidney failure, is a condition that can take two different forms: acute, when it presents itself very suddenly, and chronic, when it develops slowly over at least three months. Acute kidney failure has the potential to lead to chronic renal failure. During both types of renal failure your kidneys arent able to perform the necessary functions your body needs to stay healthy. Despite this similarity between types, the causes, symptoms, and treatments for the two kinds of renal failure vary significantly. Learning about the symptoms and causes of this disease and being able to differentiate between the two forms can be beneficial if you or a loved one have been diagnosed with renal failure.

8.3 Acidosis And Renal Failure

Metabolic acidosis occurs with both acute and chronic renal failure and with other types of renal damage. The anion gap may be normal or may be elevated. If the renal damage affects both glomeruli and tubules, the acidosis is a high-anion gap acidosis. It is due to failure of adequate excretion of various acid anions due to the greatly reduced number of functioning nephrons. If the renal damage predominantly affects the tubules with minimal glomerular damage, a different type of acidosis may occur. This is called Renal Tubular Acidosis (RTA) and this is a normal anion gap or hyperchloraemic type of acidosis. The GFR may be normal or only minimally affected. The acidosis occurring in uraemic patients 1 is due to failure of excretion of acid anions (particularly phosphate and sulphate) because of the decreased number of nephrons. There is a major decrease in the number of tubule cells which can produce ammonia and this contributes to uraemic acidosis. Serious acidosis does not occur until the GFR has decreased to about 20 mls/min. This corresponds to a creatinine level of about 0.30-0.35 mmols/l. The plasma bicarbonate in renal failure with acidosis is typically between 12 & 20 mmol Continue reading >>

    Your first, best, and cheapest option is not to use them.
    Ketostix do not measure what many people expect that they do.
    Ketostix only measure excess levels of acetoacetate, which is not the type of ketones that correlate with nutritional ketosis.
    Ketostix may show negative ketones when your blood ketones are high and then may show positive ketones when your blood ketones are low.
    Misinterpretation of what they show is one of the most common unnecessary causes of keto anxiety and wasted time. You can be perfectly successful on a ketogenic or low-carb diet without ever measuring ketones.
    Many people are already overwhelmed with learning about keto diets. Adding another layer of unnecessary complexity doesn't help the matter. Often, people are most successful on keto when they treat it as a lifestyle and not a diet. Obsessively measuring ketones can be at odds with attempting to live a keto lifestyle.
    If you decide to use Ketostix anyway, please be kind to those who answer questions here by not submitting a question that begins with I know that Ketostix are unreliable, but ...
    If you consume few enough carbohydrates and avoid excessive intake of protein, you can trust that your liver will be producing ketones within a single day. That is how human metabolism works.
    If you consume too many carbs, you will be kicked out of ketosis temporarily. However, if you once again restrict carbs, you will go right back into ketosis within 24 hours. This is because the liver can store only 100 grams of glycogen. If you restrict carbs, the liver will run out of glycogen within a day and begin burning fat instead. The liver produces ketones as a side effect of burning fat.
    As an example of how Ketostix can be misleading, it is possible to eat a high-carbohydrate meal followed by a positive Ketostix result. You may think that you cheated the system, but you didn't. It takes time for excess ketones to appear in urine. Ketostix are showing you what happened in the past before you cheated.
    If you have the time and really want to know why Ketostix will not tell you much, read pages 164 and 165 of The Art and Science of Low Carbohydrate Living by Volek and Phinney. This is the section headed by Ketones: To Measure or Not.
    If you do not have this book, read this summary:
    http://ketopia.com/why-you-need-to-stop-worrying-about-the-color-of-your-ketostix/
    Ketostix were designed to help diabetics avoid ketoacidosis which is a dangerous condition involving very high blood sugar and very high serum ketones. If you have near normal blood sugar and serum ketone levels consistent with nutritional ketosis, you don't need to worry about this.
    Ketostix only measure excess levels of acetoacetate, which is not the type of ketones that correlate with nutritional ketosis.
    The ketones that correlate with nutritional ketosis are known as beta-hydroxybutyrate. This type can be measured only with a blood ketone meter.
    There is a built-in time lag. Ketostix are measuring what has happened in the past since it takes a while for the kidneys to produce urine.
    Exercise can influence how many excess ketones are excreted.
    You can be in nutritional ketosis even when Ketostix show no excess acetoacetate. In the keto-adapted state, very little acetoacetate ketones will be excreted in urine even though blood ketones may be high.
    Note that it takes a period of four to six weeks of being in ketosis every day in order to become keto-adapted. Someone who is keto-adapted has adapted to using fat as the primary fuel for muscles and various organs. The keto-adapted brain uses ketones in place of glucose for most of its energy needs. When keto-adapted, most acetoacetate is not excreted. Instead, muscles convert it to beta-hydroxybutyrate and return it to the blood for use by the brain.
    If after all of this, you still want to use Ketostix because you bought them and cannot bring yourself to throw them away or because they are comforting in some way, here is how they may be useful.
    When you are first starting a low-carb or keto diet and transitioning into ketosis from a moderate to high-carb diet, Ketostix will confirm that your body has in fact done what biology says that it must do. It will show that your liver has begun producing ketones.
    Once you are a few days into the diet, you can give them away to a keto newbie or toss them. Note that Ketostix will eventually expire, especially if you keep them in a moist environment like a bathroom.
    If you have a medical condition that makes monitoring blood ketone levels necessary or if you are a numbers geek with spending money, you may be interested in purchasing a ketone blood meter and test strips for measuring beta hydroxybutyrate in your blood. The test strips cost somewhere between $2 and $5 per strip.
    There are a few meters to choose from.
    Precision Xtra - https://www.abbottdiabetescare.com/products/patient/pxtra-overview.html
    Nova Max Plus - http://www.novacares.com/nova-max-plus/
    CardioChek Home - http://www.healthchecksystems.com/CardioChek.cfm#home
    Most use one of the first two listed (Precision Xtra or Nova Max Plus). Some say that the Precision Xtra is the more accurate of the two. I've found that readings from these two track fairly closely with each other. The Nova Max Plus has cheaper test strips.
    To detect nutritional ketosis, look for a reading between 0.5 and 5.0 mmol / liter. Some experts recommend aiming for a level of 1.0 to 5.0 mmol / liter.
    Another option is the Ketonix Sport breath meter. This meter measures acetate in the breath. It does not require test strips.
    Acetate forms when acetoacetate spontaneously breaks down to acetate. According to Volek and Phinney (page 165 of The Art and Science of Low Carbohydrate Living), it should be linearly correlated with blood ketones. In practice, it is not as accurate as the blood meters in part because it is difficult to breathe in the same way every time you test.
    Ketonix Sport (order direct from Sweden) - https://www.ketonix.com/index.php/product/sport
    Again, remember that you can be perfectly successful on a ketogenic or low-carb diet without ever measuring ketones whether in urine, blood, or breath.
    In the final analysis, ketone concentrations are what they are. Chasing ketone concentrations often becomes as unnecessary and distracting as Ketostix. Unless you are treating epilepsy, cancer, or other medical condition, the concentration of ketones do not matter too much. You can achieve weight loss and a sense of well-being even with lower levels of ketones.
    Focus on how you feel, not on the number. Use ketone meters for interest and experimentation, but don't let the results stress you out.
    tl;dr never, unless you have read and understood this post, yet still want to use them anyway
    [If anyone has any suggestions for improving this post or correcting misinformation, let me know. I'll correct this and re-post it once in a while]

  2. anbeav

    Hallelujah!!
    tl;dr never
    If you want to do it for experimentation, go for it but please spare the rest of us the unnecessary ketosis anxiety
    edits: In addition to false negatives, ketostix commonly show false positives as in when people eat a high carb meal and think they cheated biology. Also I might remove the bit about using ketostix to monitor keto-adaptation, just asking for more posts about the issue. Also I might emphasize that people seem to already be overwhelmed with keto when starting and adding another layer of unnecessary complexity doesn't help the matter. People always talk about lifestyle, live a lifestyle and IMO living a lifestyle certainly shouldn't have to include measuring. Lastly, ketone concentrations are what they are. If you want to measure with a blood or breath meter, they are what they are and chasing ketone concentrations often becomes as unnecessary as ketostix. Unless someone has a medical condition for which a particular concentration is required for management, focus on how you feel not the number. Use the meter for interest and experimentation, but don't let it stress you out.

Metabolic Acidosis

Patient professional reference Professional Reference articles are written by UK doctors and are based on research evidence, UK and European Guidelines. They are designed for health professionals to use. You may find one of our health articles more useful. See also separate Lactic Acidosis and Arterial Blood Gases - Indications and Interpretations articles. Description Metabolic acidosis is defined as an arterial blood pH <7.35 with plasma bicarbonate <22 mmol/L. Respiratory compensation occurs normally immediately, unless there is respiratory pathology. Pure metabolic acidosis is a term used to describe when there is not another primary acid-base derangement - ie there is not a mixed acid-base disorder. Compensation may be partial (very early in time course, limited by other acid-base derangements, or the acidosis exceeds the maximum compensation possible) or full. The Winter formula can be helpful here - the formula allows calculation of the expected compensating pCO2: If the measured pCO2 is >expected pCO2 then additional respiratory acidosis may also be present. It is important to remember that metabolic acidosis is not a diagnosis; rather, it is a metabolic derangement that in Continue reading >>

Made a huge pot of bone broth before it hit, so I'm sipping that, and regular/herbal teas. Also taking meds, and hot showers/baths, and using coconut oil on my poor sore nose and lips.
