It is important to note that these side effects usually improve over time as the body adjusts to the medication.
Another potential side effect of long term use of metformin is vitamin B12 deficiency. Metformin can interfere with the absorption of vitamin B12 in the body, leading to lower levels of this essential nutrient. Vitamin B12 deficiency can cause symptoms such as fatigue, weakness, and numbness or tingling in the hands and feet. Regular monitoring of vitamin B12 levels and supplementation may be necessary for individuals on long term metformin therapy.
Metformin: Understanding the Side Effects
Metformin is a commonly prescribed medication for the management of type 2 diabetes. It is an oral medication that helps control blood sugar levels by improving insulin sensitivity and reducing glucose production in the liver. While metformin is generally well-tolerated, long-term use of the medication can lead to certain side effects that need to be understood.
It is important to note that not everyone who takes metformin will experience side effects, and the severity and frequency of side effects can vary from person to person. Additionally, many of these side effects are temporary and may go away as the body adjusts to the medication. However, it is still crucial to be aware of the potential side effects and discuss them with your healthcare provider.
Gastrointestinal Side Effects

One of the most common side effects of metformin is gastrointestinal discomfort. This includes symptoms such as nausea, vomiting, diarrhea, and abdominal pain. These side effects can be more pronounced when starting the medication or when the dosage is increased. It is recommended to take metformin with food to help reduce these symptoms.
In rare cases, metformin can cause a serious condition called lactic acidosis. This occurs when there is a buildup of lactic acid in the body, leading to symptoms such as weakness, fatigue, muscle pain, and difficulty breathing. If you experience any of these symptoms, it is important to seek medical attention immediately.
Vitamin B12 Deficiency
Long-term use of metformin can also lead to a deficiency in vitamin B12. This is because metformin can interfere with the absorption of this essential vitamin in the intestines. Vitamin B12 is important for the production of red blood cells and the functioning of the nervous system. A deficiency in B12 can cause symptoms such as fatigue, weakness, numbness or tingling in the hands and feet, and difficulty with balance.
If you are on long-term metformin therapy, your healthcare provider may recommend periodic monitoring of your vitamin B12 levels and may prescribe supplements if necessary.
Other Side Effects
In addition to gastrointestinal discomfort and vitamin B12 deficiency, metformin can also cause other side effects. These can include metallic taste in the mouth, decreased appetite, and skin reactions such as rash or itching. It is important to report any unusual or severe side effects to your healthcare provider.
It is worth noting that the benefits of metformin in controlling blood sugar levels and managing type 2 diabetes generally outweigh the potential side effects. However, it is essential to work closely with your healthcare provider to monitor and manage any side effects that may arise during long-term use of metformin.
In conclusion, while metformin is an effective medication for the management of type 2 diabetes, it is important to be aware of the potential side effects that can occur with long-term use. By understanding and monitoring these side effects, you and your healthcare provider can ensure that the benefits of metformin outweigh any potential risks.
Gastrointestinal Issues
One of the most common side effects of long-term use of metformin is gastrointestinal issues. Metformin is known to cause a range of gastrointestinal symptoms, including nausea, vomiting, diarrhea, and abdominal pain. These symptoms can be mild to severe, and can significantly impact the quality of life for individuals taking metformin.
The exact mechanism by which metformin causes gastrointestinal issues is not fully understood. It is believed that metformin may increase the production of certain hormones in the gut, which can lead to increased motility and secretion in the intestines. This can result in diarrhea and other gastrointestinal symptoms.
Nausea and Vomiting
Nausea and vomiting are common side effects of metformin use. These symptoms can occur shortly after taking the medication and may persist for several hours. Some individuals may experience mild nausea and occasional vomiting, while others may experience severe nausea and frequent vomiting. It is important to note that these symptoms can be managed with lifestyle modifications, such as taking metformin with food or dividing the daily dose into smaller, more frequent doses.
Diarrhea
Diarrhea is another common gastrointestinal side effect of metformin. It can range from mild to severe and can be accompanied by abdominal cramping and urgency to have a bowel movement. Diarrhea can be disruptive and may require individuals to make frequent trips to the bathroom. In some cases, diarrhea can be managed by adjusting the dosage or by taking an extended-release form of metformin.
Abdominal Pain
Abdominal pain is a less common side effect of metformin, but it can still occur in some individuals. This pain can be dull or sharp and may be accompanied by bloating or discomfort. If abdominal pain persists or becomes severe, it is important to consult a healthcare provider, as it may be a sign of a more serious condition.
In conclusion, gastrointestinal issues are common side effects of long-term use of metformin. Nausea, vomiting, diarrhea, and abdominal pain can significantly impact the quality of life for individuals taking this medication. It is important to work with a healthcare provider to manage these symptoms and adjust the dosage or form of metformin if necessary.
Vitamin B12 Deficiency
Long-term use of metformin can lead to vitamin B12 deficiency. Metformin reduces the absorption of vitamin B12 in the intestines, which can result in low levels of this essential vitamin in the body. Vitamin B12 is important for the production of red blood cells, DNA synthesis, and proper neurological function.
When vitamin B12 levels are low, a person may experience symptoms such as fatigue, weakness, tingling or numbness in the hands and feet, memory problems, and difficulty concentrating. Severe vitamin B12 deficiency can lead to anemia and nerve damage.
It is recommended that individuals taking metformin have their vitamin B12 levels regularly monitored by a healthcare professional. If deficiency is detected, vitamin B12 supplements may be prescribed to restore normal levels. In some cases, a higher dose or alternative form of vitamin B12, such as injections, may be necessary.
Additionally, individuals taking metformin should ensure they consume an adequate amount of vitamin B12-rich foods, such as meat, fish, dairy products, and fortified cereals. A balanced diet and regular intake of vitamin B12 can help prevent deficiency.
Lactic Acidosis
Lactic acidosis is a rare but serious side effect that can occur with the long-term use of metformin. It is characterized by the buildup of lactic acid in the blood, which can lead to a decrease in pH levels and potentially cause organ damage. Lactic acidosis can be life-threatening if not treated promptly.
The exact cause of lactic acidosis in metformin users is not fully understood, but it is believed to be related to the drug’s effect on the body’s ability to metabolize lactate, a byproduct of glucose metabolism. Metformin can inhibit the liver’s production of glucose and increase the uptake of lactate by muscle cells, leading to an accumulation of lactate in the blood.
Symptoms of lactic acidosis may include rapid breathing, abdominal pain, muscle cramps, fatigue, dizziness, and a feeling of being cold. If you experience any of these symptoms while taking metformin, it is important to seek medical attention immediately.
To reduce the risk of lactic acidosis, it is important to follow the prescribed dosage of metformin and to inform your healthcare provider of any other medications or medical conditions you have. Your healthcare provider may perform regular blood tests to monitor your lactate levels and adjust your dosage if necessary.
In rare cases, lactic acidosis can occur even when metformin is taken as prescribed. Certain factors may increase the risk, such as kidney or liver problems, alcohol abuse, dehydration, and conditions that can reduce oxygen levels in the body, such as heart failure or chronic obstructive pulmonary disease (COPD).
If lactic acidosis is diagnosed, treatment may include immediate discontinuation of metformin, supportive care to stabilize pH levels, and treatment of any underlying conditions. In severe cases, hospitalization may be required.
It is important to weigh the potential benefits of metformin in managing diabetes against the risk of lactic acidosis. For most people, the benefits of metformin outweigh the potential risks, but it is important to be aware of the signs and symptoms of lactic acidosis and to seek medical attention if they occur.
