171 Possible Causes for Bicarbonate Decreased, Hyponatremia, Potassium Decreased

  • Renal Tubular Acidosis

    […] resorption Decrease in aldosterone secretion or activity Plasma bicarbonate (mEq/L or mmol/L) Frequently 15, occasionally 10 Usually 12–20 Usually 17 Plasma potassium Usually[] Levels of potassium are usually decreased in proximal RTA although they can be normal.[] It is associated with increased renin activity, hyponatremia, hyperkalemia and volume depletion.[]

  • Proximal Renal Tubular Acidosis

    Increased alkalinity of proximal tubular cells would explain the low rate of bicarbonate reabsorption per liter glomerular filtration and the decreased rate of ammonium excretion[] This, in turn, causes inadequate secretion of protons and potassium, with decreased trapping and excretion of ammonium and decreased excretion of potassium.[] It is associated with increased renin activity, hyponatremia, hyperkalemia and volume depletion.[]

  • Diabetes Mellitus

    Bicarbonate therapy The use of bicarbonate in DKA is controversial ( 62 ) because most experts believe that during the treatment, as ketone bodies decrease there will be adequate[] In this T1D case with CKD, severe hyperglycemia in conjunction with other metabolic insults, such as uremia, hyponatremia, and hypocalcemia, probably provoked his seizure[] Comments Acetohexamide* 250 mg once/day–750 mg bid 12–24 h No longer available in US Chlorpropamide * 100 mg once/day–750 mg once/day 24–36 h Chlorpropamide : May cause hyponatremia[]

  • Hyponatremia

    15% to 20%, hyperchloremic acidosis, decreased serum bicarbonate level, potassium abnormalities (type dependent) Correct acidosis, sodium bicarbonate Salt-wasting nephropathies[] Swollen brain cells react to hyponatremic conditions by decreasing their volume over approximately 48 h by the extrusion of potassium, sodium, chloride, and organic osmolytes[] ] True hyponatremia, also known as hypotonic hyponatremia, is the most common type.[]

  • Small Bowel Obstruction

    Decreased perfusion due to a hypovolemic state potentiates the ischemia.[] potassium level) Abdominal surgery Decreased blood supply to the intestines Infections inside the abdomen, such as appendicitis Kidney or lung disease Use of certain medicines[] However, hyponatremia ( 134 mmol/L) and CT scan findings of wall thickening or a suspected closed loop were independently associated with bowel ischemia.[]

  • Cystinosis

    Acidosis-affected patients are often administered with sodium citrate and supplements of phosphorus as well as potassium.[] At follow-up, the polyuria and hyponatremia were found to persist.[] Diagnostic methods The diagnosis is based on blood and urine analysis showing features of Fanconi syndrome (metabolic acidosis, hypokalemia, hyponatremia, hypophosphatemia[]

  • Diabetic Ketoacidosis

    […] to between 7.25 and 7.30 (normal 7.35–7.45); serum bicarbonate decreased to 15–18 mmol/l (normal above 20); the person is alert Moderate: pH 7.00–7.25, bicarbonate 10–15,[] Halperin reports holding a patent on the use of sodium-linked glucose transporter 2 inhibitors to increase the excretion of water in patients with hyponatremia (US 8,518,895[] Both insulin therapy and correction of acidosis decrease serum potassium levels by stimulating cellular potassium uptake in peripheral tissues.[]

  • Acute Pancreatitis

    Ethanol increases the protein content of pancreatic juice and decreases bicarbonate levels and trypsin inhibitor concentrations.[] Serum calcium should be followed to assess for acute decrease and as part of Ranson’s criteria.[] Serum sodium and potassium are also part of the APACHE II scoring system that should be assessed frequently on these patients.[]

  • Syndrome of Inappropriate Antidiuretic Hormone Secretion

    Serum bicarbonate remains normal despite hypotonic expansion of body fluids in SIADH.[] Due to movement of potassium from the intracellular space to the extracellular space Decreased Potassium and metabolic alkalosis -, consider diuretic therapy or vomiting as[] Abstract Hyponatremia is prevalent in hospitalized patients and predicts a poor prognosis.[]

  • Diabetic Ketotic Coma

    Indeed this is much higher then expected given the relatively modest decrease in bicarbonate.[] Blood sugar will also decrease. Fluids and potassium will be given through a vein ( intravenously ). This must be done carefully.[] Two patients presented hyponatremia simultaneously. No patients had benefit with phenytoin or diazepam, and one patient got worse after them.[]
