A high lactate level in the blood means that the disease or condition a person has is causing lactate to accumulate. In general, a greater increase in lactate means a greater severity of the condition. When associated with lack of oxygen, an increase in lactate can indicate that organs are not functioning properly.

What causes high lactate levels?

Lactic acid levels get higher when strenuous exercise or other conditions—such as heart failure, a severe infection (sepsis), or shock—lower the flow of blood and oxygen throughout the body.

What is the effect of high lactate?

Higher-than-normal lactic acid levels can lead to a condition called lactic acidosis. If it's severe enough, it can upset your body's pH balance, which indicates the level of acid in your blood. Lactic acidosis can lead to these symptoms: muscle weakness.

What diseases cause high lactic acid?

The most common cause of lactic acidosis is severe medical illness in which blood pressure is low and too little oxygen is reaching the body's tissues.
...
Certain diseases can also cause the condition, including:
  • AIDS.
  • Alcoholism.
  • Cancer.
  • Cirrhosis.
  • Cyanide poisoning.
  • Kidney failure.
  • Respiratory failure.
  • Sepsis (severe infection)

What does lactate mean in a blood test?

What is a lactic acid test? This test measures the level of lactic acid, also known as lactate, in your blood. Lactic acid is a substance made by muscle tissue and by red blood cells, which carry oxygen from your lungs to other parts of your body. Normally, the level of lactic acid in the blood is low.

How is high lactate treated?

Treatment of elevated lactate levels should be determined by the underlying cause. If hypoperfusion or hypoxemia is the culprit, focus on improving perfusion to the affected tissues. In shock, treatments include fluid administration, vasopressors, or inotropes.

What does a lactate of 7 mean?

An elevated lactate is associated with increased mortality.1-7 If the lactate is cleared it is associated with. better outcome.8-12 Lactate is the best means to screen for occult severe sepsis (occult sepsis is when. the patient's blood pressure and mental status are good, but the patient is still at high risk of death ...

What is a critical lactate level?

The normal blood lactate concentration in an unstressed patient is 0.5-1 mmol/L. Patients with critical illness can be considered to have normal lactate concentrations of less than 2 mmol/L.

What are signs of lactic acidosis?

The symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite, diarrhea, fast, shallow breathing, a general feeling of discomfort, muscle pain or cramping, and unusual sleepiness, tiredness, or weakness. If you have any symptoms of lactic acidosis, get emergency medical help right away.

Can stress cause lactic acid build up?

Both intense physical activity and potent psychosocial stressors increase blood lactate. Raising lactate levels by infusing the chemical can have an anxiogenic effect.

What does lactate do for the body?

When the body has plenty of oxygen, pyruvate is shuttled to an aerobic pathway to be further broken down for more energy. But when oxygen is limited, the body temporarily converts pyruvate into a substance called lactate, which allows glucose breakdown—and thus energy production—to continue.

Does high lactate mean sepsis?

Lactate is a chemical naturally produced by the body to fuel the cells during times of stress. Its presence in elevated quantities is commonly associated with sepsis and severe inflammatory response syndrome.

What is the highest lactate level?

Elevated lactate is not clearly and universally defined but most studies use cut-offs between 2.0 and 2.5 mmol/L7 whereas “high” lactate has been defined as a lactate level > 4mmol/L in a number of studies.

Can alcohol cause high lactate levels?

Significant elevations of blood lactate are uncommon in acute ethanol intoxication. In patients with ethanol intoxication who are found to have lactic acidosis, other etiologies for the elevated lactate level should be considered.

What lactate level indicates sepsis?

Since the serum lactate level was decreased to 2 mmol/L, serum lactate level is a more sensitive marker for septic shock. Notably, serum lactate level >2 mmol/L indicates a condition that is similar to sepsis with low BP in this issue of Journal of the American Medical Association (JAMA) (3).

What is normal lactate level?

Normal lactate range is less than 2.3 mmol/L. At enrollment, patients in the second quartile (1.4 < lactate < 2.3 mmol/L) had significantly increased mortality and organ dysfunction compared with patients who had lactate ≤ 1.4 mmol/L (quartile 1) (P < 0.0001).

What is the fastest way to get rid of lactic acid?

  1. Stay hydrated. Make sure you're staying hydrated, ideally before, during, and after strenuous exercise. ...
  2. Rest between workouts. ...
  3. Breathe well. ...
  4. Warm up and stretch. ...
  5. Get plenty of magnesium. ...
  6. Drink orange juice.

How do you fix lactic acidosis?

Intravenous administration of sodium bicarbonate has been the mainstay in the treatment of lactic acidosis. Aggressive use of this therapeutic modality, however, can lead to serious complications and should therefore be considered with caution.

What does lactic acid feel like?

Muscle ache, burning, rapid breathing, nausea, stomach pain: If you've experienced the unpleasant feeling of lactic acidosis, you likely remember it. Lactic acidosis caused by intense exercise is usually temporary. It happens when too much acid builds up in your bloodstream.

What level of lactic acid is fatal?

In this retrospective cohort study, a lactate level more than 2.5 mmol/L was the best threshold to predict 28-day mortality among severe sepsis and septic shock patients.

What is lactate a marker of?

Lactate is a reliable indicator of sepsis severity and a marker of resuscitation; however, it is an unreliable marker of tissue hypoxia/hypoperfusion.

How high can lactate levels go?

It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal which is governed by a number of factors. The concentration of blood lactate is usually 1-2 mmol/L at rest, but can rise to greater than 20 mmol/L during intense exertion.

What does lactate mean in English?

English Language Learners Definition of lactate

: to produce milk.

How is lactate cleared from the blood?

Lactate is cleared from blood, primarily by the liver, with the kidneys (10-20%) and skeletal muscles doing so to a lesser degree. The ability of the liver to consume lactate is concentration-dependent and progressively decreases as the level of blood lactate increases.

When is lactate high?

A high lactate level in the blood means that the disease or condition a person has is causing lactate to accumulate. In general, a greater increase in lactate means a greater severity of the condition. When associated with lack of oxygen, an increase in lactate can indicate that organs are not functioning properly.
