    I used to use the ketostix every morning -- was in moderate zone most days. After a while I stopped checking. That was about 2 months ago. Last week, I took my daughter to college orientation session, and had some chicken nuggets at Chik-Fil-A (my only cheat in about 6 months), so when I got home I decided to check. The result was negative ketones, so I tried to go back to induction levels for a few days. It's been a week, and they still register negative every morning. Could the sticks have "gone bad"? The scale is not changing too much -- the normal fluctuations, but nothing dramatic. Should I go out and get some more ketostix, or just stick with it and not worry so much?

    The sticks have a 6month shelf life after opening. The least little moisture inside the bottle can effect the reading also as can other conditions.
    If your very curious, get a new bottle.
    Remember that some people never make the sticks change color.

  3. omgtwins

    Because Ketosis stix don't really do much when it comes to encouragment - I don't use them. There are way too many variables - you could be in ketosis and it may not show, you are'nt in ketosis but loosing weight...IMNSHO I stick to the scale once a week and the measurements every month - the clothes in the back of the closet that are slowly moving up are also better indicators. You know what you're eating - good or bad, so save some money and get rid of those sticks!

Paediatric Acid-base Disorders: A Case-based Review Of Procedures And Pitfalls

Paediatric acid-base disorders: A case-based review of procedures and pitfalls J Bryan Carmody , MD and Victoria F Norwood , MD Department of Pediatrics, Division of Pediatric Nephrology, University of Virginia, Charlottesville, Virginia, USA Correspondence: Dr J Bryan Carmody, Department of Pediatrics, Division of Pediatric Neprhology, University of Virginia, PO Box 800386, Charlottesville, Virginia 22903, USA. Telephone 434-924-2096, e-mail [email protected] , [email protected] Copyright 2013 Pulsus Group Inc. All rights reserved Acid-base disorders occur frequently in paediatric patients. Despite the perception that their analysis is complex and difficult, a straightforward set of rules is sufficient to interpret even the most complex disorders provided certain pitfalls are avoided. Using a case-based approach, the present article reviews the fundamental concepts of acid-base analysis and highlights common mistakes and oversights. Specific topics include the proper identification of the primary disorder; distinguishing compensatory changes from additional primary disorders; use of the albumin-corrected anion gap to generate a differential diagnosis for patients Continue reading >>

    Throwaway account for obvious reasons.
    Husband (55) was just diagnosed with adult-onset diabetes (misdiagnosed for 5 years as panic attacks) but refuses to do anything about it. He had a fasting glucose test (360mg/dL) and a follow-up a1c blood test (11.4%). That's literally the only testing he's had done for it.
    As soon as the initial diagnosis came back, he "fired" his primary care physician for misdiagnosing his condition. But he refuses to talk to his new PCM about it (the PCM has threatened to drop him as a patient because of it). He insists that he'll be fine, "or if not at least I know what's going to kill me."
    Won't change his diet, which has always been high in sugar. He can drink a 2liter bottle of soda a day, jokes that the suggested serving size for cinnamon buns is "all of them," etc. I've made some sneaky changes around the house. There's no snacks in easy reach. I'm cutting down on portion sizes and cooking with fewer carbs. But I have no control over what he does when he leaves for work, and I'm sure there are daily Dunkin Donut runs and fast food lunches.
    He gets blurred vision and what we used to call panic attacks but now we're calling "blood sugar events" about once a week. They're debilitating. He's unable to function for close to an hour and then shaky for another three or four. I did notice that he had a tiny cut on his foot that took forever to heal last year. In retrospect, I should have forced him to get tested then. No cardio or other issues. We regularly go on hikes with steep grades and 1,000' changes in altitude.
    I'm scared (and super pissed off) about his attitude. How long do I have to dig this grave?

    Unfortunately, he can live for many years with horrible complications. You need to figure out what kind of life/partner you want. Are you happy to be sneaky and watch your partner slowly kill himself; or do you want a partner who will take care of himself so he can be around to do fun things? Are you partners or are you his caregiver?

  3. cdn_SW

    I'm so sorry your going through this, you must be incredibly frustrated. In my opinion it's not about how long it will take to kill him, it's about what it will do to his quality of life. Two of the more common and horrible complications of diabetes are problems with the eyes and neuropathy. He could go blind or end up losing a limb. You mentioned a cut that took forever to heal, uncontrolled blood sugar makes you prone to infections that can be difficult to heal, he could end up losing a toe, foot, or part of his leg. Neuropathy can also be horribly painful.
    Your husband needs to get a grip on dealing with this, it's really not that difficult once you make a decision to make some changes and get the proper treatment. You may also need to let him know whether or not you feel you would be able to be his caregiver if his health goes to shit due to his own negligence. It's a harsh reality, but better to come to grips with it now than when it's too late. It's hard to give a timeline, like in many things some people seem to fair reasonably well even with horrible control, and others may do all the right things and still end up with complications. Hopefully you can talk some sense into your husband, maybe have him google some images of diabetic neuropathy or diabetic foot ulcers, and see if that is enough to scare him into doing something.

What is ALKALOSIS? What does ALKALOSIS mean? ALKALOSIS meaning - ALKALOSIS pronunciation - ALKALOSIS definition - ALKALOSIS explanation - How to pronounce ALKALOSIS? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6Uu... Alkalosis is the result of a process reducing hydrogen ion concentration of arterial blood plasma (alkalemia). In contrast to acidemia (serum pH 7.35 or lower), alkalemia occurs when the serum pH is higher than normal (7.45 or higher). Alkalosis is usually divided into the categories of respiratory alkalosis and metabolic alkalosis or a combined respiratory/metabolic alkalosis. Respiratory alkalosis is caused by hyperventilation, resulting in a loss of carbon dioxide. Compensatory mechanisms for this would include increased dissociation of the carbonic acid buffering intermediate into hydrogen ions, and the related excretion of bicarbonate, both of which lower blood pH. Hyperventilation-induced alkalosis can be seen in several deadly central nervous system diseases such as strokes or Rett syndrome. Metabolic alkalosis can be caused by repeated vomiting, resulting in a loss of hydrochloric acid within the stomach content. Severe dehydration, and the consumption of alkali are other causes. It can also be caused by administration of diuretics and endocrine disorders such as Cushing's syndrome. Compensatory mechanism for metabolic alkalosis involve slowed breathing by the lungs to increase serum carbon dioxide, a condition leaning toward respiratory acidosis. As respiratory acidosis often accompanies the compensation for metabolic alkalosis, and vice versa, a delicate balance is created between these two conditions. Metabolic alkalosis is usually accompanied by low blood potassium concentration, causing, e.g., muscular weakness, muscle pain, and muscle cramps (from disturbed function of the skeletal muscles), and muscle spasms (from disturbed function of smooth muscles). It may also cause low blood calcium concentration. As the blood pH increases, blood transport proteins, such as albumin, become more ionized into anions. This causes the free calcium present in blood to bind more strongly with albumin. If severe, it may cause tetany.

(Video) Overview of Buffering and the Henderson-Hasselbalch Equation By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincents Ascension Health, Birmingham Metabolic alkalosis is primary increase in bicarbonate (HCO3) with or without compensatory increase in carbon dioxide partial pressure (Pco2); pH may be high or nearly normal. Common causes include prolonged vomiting, hypovolemia, diuretic use, and hypokalemia. Renal impairment of HCO3 excretion must be present to sustain alkalosis. Symptoms and signs in severe cases include headache, lethargy, and tetany. Diagnosis is clinical and with arterial blood gas and serum electrolyte measurement. The underlying condition is treated; oral or IV acetazolamide or hydrochloric acid is sometimes indicated. Metabolic alkalosis is bicarbonate (HCO3) accumulation due to Intracellular shift of hydrogen ion (H+as occurs in hypokalemia ) Regardless of initial cause, persistence of metabolic alkalosis indicates that the kidneys have increased their HCO3 reabsorption, because HCO3 is normally freely filtered by the kidneys and hence excreted. Volume depletion and hypokalemia are the most common stimuli for increa Continue reading >>

    metformin and lactic acidosis

    I am hoping that I can get some guidance from the members here. There are many of you that have a wealth of information on diabetes and things related so please bear with me. I went to the doctor yesterday and finally asked her for metformin er and was all set to try it out. Then I read the paper that came with it from the pharmacy. The warning about lactic acidosis stopped me in my tracks. Now I am afraid to take it. I searched the posts her a DD about lactic acidosis and I also found that some members said it caused them to be really fatigued. Another member posted that she had trouble with exercise because it caused leg cramps. I feel so overwhelmed now. I really wanted to try it out I believe it could help me but I don't want to put my life at risk to try it. I looked up lactic acidosis and I was reading about the bloods ph and acid in your blood. I have a problem with uric acid in my blood but I believe that is not related to lactic acidosis. I have had a problem with kidney infections and a lot of crystals in my urine and kidney stones the past year, but I believe my kidney function is ok. Does metformin cause lactic acidosis very often? Are the symptoms of lactic acidosis easy enough to pick up on so it can be caught early. I am sorry I am such a worry wart. Thank you in advance for any guidance/reassurance from you.

    All I can tell you is that millions upon millions take met with 0 issues. You are reading the absolute worst side affects. Have you see tv commericails on meds that is any meds. They say could cause heart attack, fatigue, even death no kidding. I been on met and so has my diabetic family and 0 issues other than a tad of diahrea. To me its extemely rare many here are on met me a very very long time on it. What am I saying to me its about the best D med out there other than exercise its free. It is just my opion for what its worth, I know others might have other ideas and of course its is there opinion also. Some take b-12 if they get fatigued on met, I do not get that way, all I can say is to me its as safe as can be.

    Every drug has potential side effects. Some more common than others. I'm not sure of the exact specifics, but I believe that for a side effect to be listed, it needs to happen in 1% of the people that take it.
    My husband has been on met with no side effects other than a little bit of tummy trouble. I have a dozen local diabetic friends (through volunteer work) that are also on it, and have no side effects. I do have one friend who reacts to everything and has no issues with it. I think i've only seen people with this issue a couple of times after about 15 years online haunting a variety of message boards.
    Take for example my warfarin. It can cause bleeding. Even a baby aspirin can cause this. And it does happen to some people. But the vast majority of folks don't have issues.
    Do you have some history of lactic acidosis? Or is this simply general anxiety over something new?
    All meds are a cost benefit analysis. Do you want to try the drug to alleviate a serious issue ( like high blood sugar) or do you decide to refuse it on the basis of a rare side effect and maybe get into trouble due to glucose issues? Why not try it? Discuss with your phamacist what to look for if you are worried. But basically it is a safe, effective drug.

In its pure form, it manifests as alkalemia (pH >7.40). As a compensatory mechanism, metabolic alkalosis leads to alveolar hypoventilation with a rise in arterial carbon dioxide tension (PaCO2), which diminishes the change in pH that would otherwise occur.
