Antidote For Metformin

Metformin Litfl Life In The Fast Lane Medical Blog

Metformin rarely causes hypoglycaemia but it can cause a profound lactic acidosis in overdose and in patients with renal failure. Used therapeutically to inhibit glucogenogenesis and stimulate peripheral glucose uptake, in toxic doses it causes a profound lactaemia. All the mechanisms are unclear but it is in part due to the inhibition of gluconeogenesis (which lactate is required). Therefore in healthy individuals there is some build up of lactate, this is normally excreted in the urine but at impaired renal function or an acute overdose there is excess lactate. It is not metabolised and excretion relies solely on renal excretion A lactic acidosis in the context of therapeutic metformin has a high mortality rate and an underlying cause (sepsis) needs to be managed Metformin overdose is usually benign but doses > 10 grams are concerning Lactic acidosis will occur in these individuals who are susceptible (renal, cardiac, respiratory failure) or in patients who have ingested co-ingestants or are on medications that impair cardiac and renal function Severe lactic acidosis usually manifests with non-specific symptoms several hours later but can progress to coma, shock and death Childr Continue reading >>

    Insulin plays a key role in helping sugar (glucose) enter your cells, thus providing them energy. When your cells don't get the glucose they need for energy, your body begins to burn fat for energy, which produces ketones. Ketones are acidic and so when they build up in the blood, they make the blood more acidic, leading to the condition called diabetic ketoacidosis (DKA).
    Now, in type-1 diabetes, there is no insulin production whereas in type-2, there is impairment of insulin production. Thus why Type-2 diabetic people hardly get DKA.
    Note: Diabetic ketoacidosis is a serious condition that might lead to diabetic coma or even death.

    In order for the cells in your body to access the glucose in your bloodstream so they can use it as energy they need insulin. Insulin acts like a key, opennin the cell door to allow the entry of glucose. Type 1 diabetics produce no insulin and need to inject it, thus the amount of insulin they have is strictly limited. Once they run out of insulin the glucose remains in the blood stream. If this occurs over a long period of time their blood glucose levels will rise due to the release of glucose from the liver. High blood sugar levels causes ketoacidosis which leads to coma and death.

    Although type 2 diabetics suffer from insulin resistance, the condition rarely has an absolute negative effect on the bodies ability to convert glucose to usable energy. Type 1 diabetics have little or no ability to produce insulin. With the exception of neural cells, the rest of the body which without insulin is experiencing starvation, will consume its own tissues. (this is how people have endured periods of famine). This process however produces by products that eventually overwhelm the body's ability to process toxins.
