Metabolic Acidosis: Practice Essentials, Background, Etiology

Metabolic acidosis is a clinical disturbance characterized by an increase in plasma acidity. Metabolic acidosis should be considered a sign of an underlying disease process. Identification of this underlying condition is essential to initiate appropriate therapy. (See Etiology, DDx, Workup, and Treatment.) Understanding the regulation of acid-base balance requires appreciation of the fundamental definitions and principles underlying this complex physiologic process. Go to Pediatric Metabolic Acidosis and Emergent Management of Metabolic Acidosis for complete information on those topics. An acid is a substance that can donate hydrogen ions (H+). A base is a substance that can accept H+ ions. The ion exchange occurs regardless of the substance's charge. Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids. Hydrochloric acid (HCl) is considered a strong acid because it is present only in a completely ionized form in the body, whereas carbonic acid (H2 CO3) is a weak acid because it is ionized incompletely, and, at equilibrium, all three reactants are present in body fluids. See the reactions below. Th Continue reading >>

    I've been enjoying reading posts people have made about ketosis, because my husband is complaining a lot about my breath and is very worried about my health on this diet. I'm a 39 year old female and have been eating paleo for about 6 months. I have lost about 8 pounds (went from 112 to 104), but I like being thin. My husband, however, is worried about my weightloss, and wants me to change my diet because of my breath... He tells me my breath is "weird" and smells like a strong "chemical" and that sometimes he doesn't want to kiss me. I don't like the metallic taste in my mouth either. So I started eating a lot of fruit and squash every day and that seems to help tone down the chemically breath sometimes.
    So two questions:
    Does anyone else have an icky "metallic" taste in their mouth due to ketosis? And is this a dangerous sign?
    Is it unhealthy or dangerous to one's health to be in ketosis often...? My husband worries that it could potentially be breaking down my muscles and/or putting strain on my organs if I don't eat more carbs...?

    1) I did when I was VLC and in frequent ketosis, along with constant thirst. It's just a sign that you're in ketosis, it's the ketones on your breath and not necessarily dangerous....but...
    2) For some women, it can be. Keep a very close eye on your menstrual cycle and your weight loss. If your periods become irregular or stop, or you frequently feel fatigued and cold, then you need more carbs.
    The reason behind this is, is that when you're VLC and in ketosis you hardly ever spike your insulin even slightly. This can lead to your body thinking that it's not getting enough food, and the lack of insulin leads to low leptin and low active T3, (thyroid) the result being that you stop losing weight and your body shuts down your reproductive capabilities. (You also will have high levels of t4, as the rT3 is converted to this instead of active T3. Being in ketosis a lot is quite demanding on the liver)
    Add some more starch! (as you have done). You can be low carb and maintain weight without being in ketosis all the time. If you don't need to lose more weigh then it's not necessary. You probably need 40-70g carbs a day
    104 - lucky you!

    Wow, thank you so much for the helpful information! I really do appreciate it. This is really intestesting to me, and I would like to learn more about this. My doctor recommended the paleo diet to me in the first place because my insulin is very low. Ironically, my Thyroid T3 levels are also very low... (I'm on 60 mg of Armour Thyroid daily for this). I almost always feel cold and have raynauds (both of these symptoms since I was about 13 yrs old, way before starting paleo diet). However, my menstral cycle is relatively normal... but some months very painful cramping, and other months none at all. I have no idea about the current condition of my liver... But I'm very interested in how this diet could be affecting my liver. If you have any recommended readings for me to learn more about ketosis or any potential dangers to my liver or thyroid, I would be grateful for you to pass them along. Thank you again!!

4 Signs of a Potassium Deficiency - How to Avoid Potassium Deficiency Both cramps and fatigue can be clear indicators of a potassium deficiency. Add foods that contain this mineral to your diet to avoid major health problems. Potassium deficiency can affect your nerves and their interaction with your muscle cells in your digestive tract, the heart, and other bodily systems. Most of the potassium in your body is found in your cells. When you have a balanced daily diet you keep your potassium levels stable with ease. If your diet is very poor, on the other hand, choosing unhealthy products or missing some key sources, youll have a deficiency in potassium. But how do you know if you have a potassium deficiency? In todays article well explain the signs. Pay attention to see if you have any of them. 1. You feel potassium deficiency: youre tired and weak The first symptoms of a potassium deficiency are usually muscle aches, cramps, and abnormal weakness. This weakness will not just affect your arms and legs, but also your respiratory and gastrointestinal muscles. Low potassium levels prevent your muscle cells from rapidly recharging their energy stores. This causes them to have difficulty contracting. Weakness, muscle spasms, and tingling or numbness in the muscles could indicate that your potassium deficiency is getting worse. If you already have any of these symptoms, we recommend that you go the doctor immediately for an evaluation. 2. You have an irregular heartbeat A prolonged lack of potassium in the body can affect your heart by altering its normal function. The first symptom of this will be an irregular heartbeat with no apparent cause. Its normal for this to happen if you run too hard when youre not prepared, for example. Whats not normal is for it to occur when youre simply following your normal routine. If you have a prolonged potassium deficiency, you can eventually develop structural and functional changes in your kidneys. A lack of potassium can also slow down your heart rate and cause dizziness, as a result. There are different types of arrhythmia. Some cause the heart to beat too fast, while others make it work more slowly. In the most severe cases, your heart could begin skipping beats. All types of arrhythmias can cause a variety of symptoms, ranging from dizziness to fainting. An irregular heartbeat due to any cause can be accompanied by shortness of breath, chest pain, and sweating. 3. High blood pressure There are many factors that influence your blood pressure, including family history, being overweight, and your consumption of salt. A deficiency of potassium can also be a cause. In fact, both too much and too little potassium can trigger changes in your blood pressure. According to several studies, eating too much salty food and too few fruits and vegetables can lead to high blood pressure. 4. Cramping The activity and resting states of your muscles depend on potassium. Relaxation can be voluntary or involuntary, depending on the type of muscle you are working. When you have a deficit of potassium, the muscle is kept in a contracted state that causes cramping. If youre familiar with frequent muscle spasms in your legs, for example, it could be due to a lack of potassium. This is very common in athletes who train a lot. If this is the case for you, its a good idea to consume sports drinks that are rich in electrolytes and potassium from time to time. Foods that are rich in potassium Whenever we talk about potassium, people always think that bananas are the best source of it. Although its true that this fruit does have a good concentration of potassium, its not your only option. Among the foods that can naturally help you get the amount of potassium you need, youll find: Chard This vegetable is easy to grow at home and everyone should try it. Just 100 grams provides 380 mg of potassium. You can consume it in salads or smoothies. Bananas Its well-known that bananas are rich in potassium, providing 370 mg per 100 grams of flesh. Just remember that if youre diabetic, you shouldnt consume too much of this fruit. Potatoes If youre the type of person who enjoys some good mashed potatoes, youve probably never experienced any of the above symptoms. Potatoes pack 418 mg of potassium in every 100 grams. To keep from losing this mineral, its best to consume potatoes that have been baked, grilled, or steamed. Remember to avoid fried potato dishes. Cabbage This is another seasonal vegetable that provides 450 mg of potassium per 100 grams. Our favorite options for this vegetable are in salads or baked dishes. Avocado The avocado provides 487 mg of potassium per 100 grams. You can enjoy it in guacamole, on top of a salad, or in a sandwich. Spinach Spinach is an excellent vegetable that you can add to a variety of dishes, which provides 554 mg of potassium per 100 grams. 4 Signs of a Potassium Deficiency - How to Avoid Potassium Deficiency

Comments On Potassium Balance In Acidosis

Got this question from another forum by a member there, and it really puzzled me ... can you answer it ?! I was watching Dr.Kudrath lectures, and I think theres something contradictory in what he said. Now let us try to discuss this and find out whats going on exactly. First let us use the terms carefully : K Excretion is the total of what is filtered of K added to what is (secreted) of K ... I think we agree on that. Now, in acidosis (whether its chronic or acute) Potassium starts to go out from the cells in the body into the blood, so that the cells can uptake Hydrogen inside them (to try and buffer the excessive Hydrogen ions in the blood), this leads to HypERkalemia (excessive K in the ECF) ... Okay, since this happens the filtered load of potassium (which equals GFR x Concetration of K in blood) Increases (since concent.of k in blood increased..hyperkalemia remember) therefore, what is filtered of Potassium increases (whether the acidosis is acute or chronic) ... and this means also that whether the acidosis is acute or chronic, the excreted amount of K will be increased regardless. Now, for (secretion) of K : if the acidosis is acute, carbonic anhydrase in the Distal Tubule Continue reading >>

All the diet info you need if you're a kidney patient: http://nhfkp.com/hope Read the full article: http://newhopeforkidneypatients.com/p... When it comes to potassium, some kidney patient may be misinformed, thinking that potassium is basically a dangerous thing to avoid. In fact, you DO NEED potassium, even if you suffer from kidney disease. Eating a well thought diet, filled with fruits and veggies is always a Positive thing, at the point that it is helping some patients reversing their kidney disease: https://www.youtube.com/watch?v=F4Bt0... Having Kidney Disease means that your kidney arent operating at their best, or that they arent operating at all. So all the wastes and excesses wont be eliminated through the urinary system as they should. This could lead to high potassium levels. High potassium level can cause symptom such as: Weakness, Depression, Dehydration, Heart problems, Paralysis, Kidney failure, Renal necrosis and many others. Most dietician recommend an intake of 2 to 5grams of potassium a day for healthy people. Kidney patient would need less than this. The right daily potassium intake for a stage 4 patient would be no more than 2,5grams. However, potassium intake should always be matched to the blood potassium level showed in blood analysis. High potassium foods and Low Potassium Foods Here is the list of high potassium foods and Low Potassium Foods subdivided by potassium levels http://newhopeforkidneypatients.com/p... There are a number of tips that can help you reduce potassium levels: Focus on a balanced diet, full of fresh fruit and vegetables. If you eat high potassium vegetables, leach them first. Limit consumption of high potassium foods. All foods have a quantity of potassium, so eat a variety of foods but watch out for portion size. Avoid consuming liquid from canned vegetables, fruit and from cooked meat. Avoid salt substitutes. Read food labels low salt foods can contain a source of potassium as a salt substitute. It has been proven that exercising regularly can reduce potassium levels. Magnesium, Garlic and Calcium can reduce and balance potassium levels. http://newhopeforkidneypatients.com https://www.youtube.com/user/00kidney https://www.facebook.com/kidney1 Tags: potassium high potassium foods potassium levels high potassium levels low potassium diet food high in potassium Low Potassium Foods how to lower potassium potassium diet potassium kidney potassium kidney disease high potassium blood levels potassium leaching potassium ckd potassium renal


Potassium's role in acid-base balance Acidosis: More Hydrogen ions are in extracellular fluid, so they move into the cell. The keep things balanced, Potassium moves into extracellular fluid, and hydrogen moves in to the cell, causing HYPERKALEMIA Alkalosis: More hydrogen ions are inside the cell, so Potassium moves in the cell and hydrogen moves back out to balance things. This causes HYPOKALEMIA What puts someone at risk for Hypokalemia? -Not eating enough Potassium -IV fluids potassium-deficient -TPN lacking Potassium -Severe GI problems (Intestinal fluids contain large amounts of Potassium) -Kidney problems (new kidney, high urine glucose levels causing osmotic diuresis, renal tubular acidosis, magnesium depletion, Cushing's syndrome, and periods of high stress) -Drugs (diuretics, corticosteroids, insulin, cisplatin, and certain antibiotics) -Excessive secretion of insulin may shift potassium into cells (with large amts of dextrose solution) -Patients with asthma receiving adrenergics such as epinephrine or albuterol What to look for with Hypokalemia: -MUSCLES: skeletal muscle weakness, esp in the legs -paresthesia develops, leg cramps occur, DTR may be decreased or absent -Rare Continue reading >>

    Ketones are released when your body is in ketosis, which is basically hardcore fat burning mode. Certain toxins are stored in fat, among other things. Burning fat releases all this stuff into your blood stream, and it shows up in your urine. You cannot see ketones, you use urine testing strips to check your ketone content.
