Learn about the relationship between metformin, a commonly prescribed medication for diabetes, and the potential risk of lactic acid buildup in the body. Understand the symptoms, causes, and treatment options for lactic acidosis, a rare but serious side effect of metformin use.
Metformin and Lactic Acid Build Up: Causes, Symptoms, and Management
Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It helps to lower blood glucose levels by improving the sensitivity of the body’s cells to insulin. However, one potential side effect of metformin is the build up of lactic acid in the body, which can lead to a condition called lactic acidosis.
Lactic acidosis occurs when there is an imbalance between the production and elimination of lactic acid in the body. Normally, lactic acid is produced as a byproduct of glucose metabolism and is quickly cleared from the bloodstream. However, in certain situations, such as when taking metformin, the body may not be able to clear lactic acid efficiently, leading to its accumulation.
It is important to note that lactic acidosis is a rare but serious side effect of metformin. Most people who take metformin do not experience lactic acidosis, and the risk of developing this condition is low. However, individuals with certain risk factors may be more susceptible, such as those with impaired kidney function or liver disease.
If left untreated, lactic acidosis can be life-threatening. Symptoms may include weakness, fatigue, difficulty breathing, abdominal pain, and an irregular heartbeat. If you are taking metformin and experiencing any of these symptoms, it is important to seek medical attention immediately.
The best way to prevent lactic acidosis while taking metformin is to follow your healthcare provider’s instructions and be aware of the signs and symptoms of this condition. It is also important to have regular check-ups to monitor your kidney and liver function. If you have any concerns or questions about metformin and lactic acid build up, be sure to discuss them with your healthcare provider.
What is Metformin?
Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It belongs to a class of drugs called biguanides, which work by decreasing the amount of glucose produced by the liver and improving the body’s response to insulin. Metformin helps lower blood sugar levels and is often used in combination with other medications or lifestyle changes to manage diabetes.
Metformin is available in both immediate-release and extended-release formulations. The immediate-release form is usually taken multiple times a day with meals, while the extended-release form is taken once daily. The dosage and administration of Metformin may vary depending on the individual’s needs and response to the medication.

Metformin works by reducing the amount of glucose produced by the liver and increasing the body’s sensitivity to insulin. Insulin is a hormone that helps regulate blood sugar levels by allowing glucose to enter cells, where it can be used for energy. In people with type 2 diabetes, the body does not effectively use insulin, leading to high blood sugar levels.
Metformin helps improve insulin sensitivity by activating an enzyme called AMP-activated protein kinase (AMPK). This enzyme plays a key role in regulating cellular energy metabolism and glucose uptake. By activating AMPK, Metformin helps lower blood sugar levels by increasing glucose uptake in muscle cells and decreasing glucose production in the liver.
Benefits of Metformin
Metformin has been shown to have several benefits for individuals with type 2 diabetes. Some of the benefits include:
- Lowering blood sugar levels
- Improving insulin sensitivity
- Reducing the risk of cardiovascular complications
- Assisting with weight loss
- Lowering LDL cholesterol levels
- Reducing the risk of certain cancers
It is important to note that Metformin should not be used as a substitute for a healthy lifestyle, including regular exercise and a balanced diet. It is always recommended to consult with a healthcare professional before starting or changing any medication regimen.
What is Lactic Acid Build Up?
Lactic acid build up, also known as lactic acidosis, is a condition that occurs when there is an accumulation of lactic acid in the bloodstream. Lactic acid is a byproduct of anaerobic metabolism, which occurs when the body is unable to produce enough oxygen to meet its energy needs. This can happen during intense exercise or in certain medical conditions.
Normally, lactic acid is quickly metabolized by the liver and other tissues. However, when there is an excessive production of lactic acid or a decrease in its clearance, lactic acid levels can rise, leading to lactic acidosis. Metformin, a commonly prescribed medication for type 2 diabetes, has been associated with an increased risk of lactic acidosis in certain situations.
Causes
There are several factors that can contribute to the build-up of lactic acid when taking metformin. These include:
- Inadequate oxygen supply: Metformin can reduce the amount of oxygen reaching the cells, leading to an anaerobic environment where lactic acid is produced.
- Impaired metabolism: Metformin can interfere with the normal metabolic processes in the body, causing a disruption in the breakdown of glucose and resulting in lactic acid accumulation.
- Reduced liver function: The liver plays a crucial role in clearing lactic acid from the bloodstream. Metformin can affect liver function, impairing its ability to remove lactic acid efficiently.
- Dehydration: Metformin can increase the risk of dehydration, which can contribute to lactic acid build-up as the body’s fluid balance is disrupted.
- Drug interactions: Certain medications, when taken in combination with metformin, can increase the risk of lactic acidosis. This can include drugs that also affect liver function or those that impair kidney function, as the kidneys are involved in lactic acid clearance.
It is important to note that lactic acidosis is a rare but serious side effect of metformin. Most people who take metformin do not experience this condition. However, individuals with underlying health conditions, such as kidney or liver disease, may be at a higher risk.
Possible Causes of Lactic Acid Build Up
Lactic acid build up, also known as lactic acidosis, can occur as a result of various factors. Here are some possible causes:
- Metformin: Metformin is a medication commonly prescribed to treat type 2 diabetes. While it is generally safe and effective, it can rarely cause lactic acidosis as a side effect. This is more likely to occur in individuals with kidney or liver problems, as these organs play a crucial role in metabolizing metformin.
- Reduced oxygen supply: Lactic acid is produced when the body’s cells don’t receive enough oxygen. This can happen in conditions such as severe respiratory infections, heart failure, or shock.
- Intense exercise: During intense exercise, the body may not be able to supply enough oxygen to the muscles, leading to the production of lactic acid. This is known as exercise-induced lactic acidosis.
- Alcohol consumption: Excessive alcohol consumption can impair liver function, leading to a buildup of lactic acid in the body.
- Severe infections: Certain severe infections, such as sepsis, can cause lactic acidosis as a result of tissue damage and reduced oxygen supply.
It is important to note that lactic acidosis is a rare but potentially serious condition. If you are taking metformin or experiencing symptoms such as weakness, fatigue, rapid breathing, or abdominal pain, it is important to seek medical attention immediately.
Role of Metformin in Lactic Acid Build Up
Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It works by reducing glucose production in the liver and increasing the body’s sensitivity to insulin. However, one of the potential side effects of metformin use is lactic acid build up, also known as lactic acidosis.
Lactic acidosis occurs when there is an accumulation of lactic acid in the blood. This can happen when the body is unable to clear lactate, a byproduct of glucose metabolism, efficiently. While lactic acidosis is rare, it can be a serious condition that requires immediate medical attention.
Mechanism of Lactic Acid Build Up
The exact mechanism by which metformin leads to lactic acidosis is not fully understood. However, it is believed to involve the inhibition of mitochondrial respiratory chain complex I, which impairs the oxidation of glucose and increases the production of lactate. Additionally, metformin may also reduce the clearance of lactate by inhibiting lactate transporters in the liver and kidneys.
Furthermore, certain factors can increase the risk of lactic acidosis in individuals taking metformin. These include kidney or liver dysfunction, alcohol abuse, dehydration, and the use of other medications that can interfere with lactate metabolism.
Monitoring and Prevention
To minimize the risk of lactic acidosis, it is important for healthcare providers to carefully monitor patients who are taking metformin. This includes assessing kidney and liver function before starting treatment and periodically thereafter. Additionally, patients should be educated about the signs and symptoms of lactic acidosis, such as muscle pain, weakness, rapid breathing, and stomach discomfort.
If lactic acidosis is suspected, metformin should be discontinued immediately, and the patient should receive appropriate medical care. Treatment may involve the administration of intravenous fluids and medications to correct the acid-base imbalance and support organ function.
Conclusion
While metformin is generally safe and effective for the management of type 2 diabetes, it is important to be aware of the potential risk of lactic acidosis. Healthcare providers should carefully monitor patients for signs of lactic acidosis and take appropriate measures to prevent and manage this condition.
