Metabolic alkalosis is an acid-base disorder in which the pH of tissue is elevated beyond the normal range (7.35–7.45). This is the result of decreased hydrogen ion concentration, leading to increased bicarbonate (HCO − 3), or alternatively a direct result of increased bicarbonate concentrations.
In contrast to DKA, serum glucose levels in HHS are extremely high, usually greater than 40-50 mmol/L (600 mg/dL). [6] Metabolic acidosis is absent or mild. [6] A temporary state of confusion (delirium) is also more common in HHS than DKA. HHS also tends to affect older people more. DKA may have fruity breath, and rapid and deep breathing. [6]
Accordingly, measurement of base excess is defined, under a standardized pressure of carbon dioxide, by titrating back to a standardized blood pH of 7.40. The predominant base contributing to base excess is bicarbonate. Thus, a deviation of serum bicarbonate from the reference range is ordinarily mirrored by a deviation in base excess.
The version with seven tests is often referred to by medical professionals in the United States as the "CHEM-7", or "SMA-7" (Sequential Multiple Analysis-7). [1] The seven parts of a CHEM-7 are tests for: Four electrolytes: sodium (Na +) [2] potassium (K +) [3] chloride (Cl −) [4] bicarbonate (HCO 3 −) or CO 2 [5] blood urea (BU), blood ...
Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]
Prediabetes is a condition where blood sugar levels are elevated but not high enough to be diagnosed as diabetes. It’s often detected through blood tests such as the A1C test, which measures ...
Low insulin levels and/or insulin resistance prevent the body from converting glucose into glycogen (a starch-like source of energy stored mostly in the liver), which in turn makes it difficult or impossible to remove excess glucose from the blood. With normal glucose levels, the total amount of glucose in the blood at any given moment is only ...
the 2001 observation, that non-diabetic offspring of type 2 diabetics had increased arterial stiffness and neuropathy despite normal blood glucose levels, [59] the 2008 observation, that non-diabetic first-degree relatives of diabetics had elevated enzyme levels associated with diabetic renal disease [60] and nephropathy.
