What You'll Learn
Metformin is used to treat type 2 diabetes
Metformin is a medication used to treat type 2 diabetes. It belongs to a class of drugs called biguanides, which work by controlling blood glucose (sugar) levels. Type 2 diabetes is a condition where the body does not use insulin effectively, resulting in high blood sugar levels. Metformin helps to lower blood sugar by reducing glucose absorption from food and increasing the body's response to insulin. It is typically taken orally as a tablet or liquid solution, usually with meals to minimise side effects.
Metformin is often prescribed in combination with other medications, including insulin, to manage blood sugar levels. While it is commonly used for type 2 diabetes, it is not suitable for treating type 1 diabetes. This is because type 1 diabetes is characterised by the body's inability to produce insulin, whereas type 2 diabetes involves impaired insulin utilisation.
As with any medication, metformin may cause side effects, although not everyone experiences them. Common side effects include nausea, vomiting, diarrhoea, abdominal pain, and loss of appetite. More rarely, metformin can cause lactic acidosis, a serious condition characterised by symptoms such as stomach discomfort, decreased appetite, diarrhoea, and severe muscle pain. If left untreated, lactic acidosis can be life-threatening. Therefore, it is crucial to seek immediate medical attention if these symptoms occur.
Additionally, metformin can cause vitamin B12 deficiency, leading to symptoms like fatigue, breathlessness, and dizziness. Long-term use of metformin may also increase the risk of developing serious health conditions such as heart disease, stroke, kidney problems, nerve damage, and eye complications. It is important for individuals taking metformin to be vigilant about monitoring their blood sugar levels and maintaining a healthy diet and exercise regimen.
While metformin is a valuable tool in managing type 2 diabetes, it should be used under medical supervision. Patients taking metformin should be aware of potential side effects and seek medical advice if they experience any adverse reactions or if their condition persists or worsens.

Lactic acidosis is a rare but serious side effect
Metformin is a prescription medication used to treat type 2 diabetes and high levels of insulin resistance. It is a low-cost, daily prescription medication that helps to control blood sugar levels in people with type 2 diabetes. While metformin is generally well-tolerated, it can cause some side effects, including nausea, diarrhoea, bloating, and, in rare cases, a serious condition called lactic acidosis.
The symptoms of lactic acidosis include abdominal or stomach discomfort, decreased appetite, diarrhoea, fast or shallow breathing, a general feeling of discomfort, severe muscle pain or cramping, and unusual sleepiness, tiredness, or weakness. These symptoms can appear quickly and are often severe. They usually occur when other serious health problems are present, such as a heart attack or kidney failure.
If you experience any symptoms of lactic acidosis, it is important to seek immediate emergency medical help. Discontinuing the use of metformin and starting supportive measures in a hospital setting, including prompt hemodialysis, are recommended. It is also crucial to inform your doctor or healthcare provider if you have any concerns or experience any other side effects while taking metformin.
While metformin can cause lactic acidosis, it is important to note that this side effect is rare. The risk of developing lactic acidosis while taking metformin can be increased by certain factors, such as kidney disease, heart attack, or taking certain other medications in combination with metformin. It is always important to consult with a doctor or healthcare professional before taking any medication, including metformin, to ensure that it is safe and appropriate for your individual health status.

Vitamin B12 deficiency is a common side effect
Metformin is a prescription medication used to treat type 2 diabetes and high levels of insulin resistance. It is a low-cost, daily medication that belongs to a class of drugs called biguanides. It is important to note that metformin is not suitable for treating type 1 diabetes as it cannot address the underlying issue of insulin production in patients with this condition.
While metformin is generally considered effective and safe, it can cause various side effects, although not everyone experiences them. One of the most common side effects is vitamin B12 deficiency, especially in individuals who have been taking the medication for four years or more. Vitamin B12 deficiency can lead to a range of symptoms, including feeling very tired, breathless, and faint. In some cases, it can even cause neuropathy, resulting in numbness and tingling in the hands and feet, and potentially leading to memory problems.
If you are experiencing any of these symptoms, it is important to consult your doctor or healthcare provider. They may recommend checking your vitamin B12 serum levels through a blood test. If your vitamin B12 levels are indeed low, your doctor may prescribe vitamin B12 supplements to help correct the deficiency and alleviate the associated symptoms.
It is worth noting that metformin has also been associated with a reduced risk of musculoskeletal pain in patients with type 2 diabetes. A cross-sectional study involving 21,889 participants from the UK Biobank found that those taking metformin had lower odds of reporting back, knee, neck/shoulder, and multisite musculoskeletal pain compared to those not taking the medication. This suggests that metformin may have a protective effect against musculoskeletal pain, particularly in women.
While muscle pain may not be a direct side effect of metformin, it is crucial to be vigilant and consult your doctor if you experience any unusual or persistent muscle pain while taking this medication, as it could be indicative of a more serious underlying condition. Additionally, metformin may cause other side effects, such as nausea, diarrhea, and bloating, which usually resolve on their own as your body adjusts to the medication. However, more serious side effects like dizziness or muscle pain should be addressed immediately with your healthcare provider.

Metformin may cause an allergic reaction
Metformin is a medication used to treat type 2 diabetes and high levels of insulin resistance. It is a low-cost, daily prescription medication that helps control blood sugar levels in people with type 2 diabetes. While metformin is generally well-tolerated, it may cause certain side effects, including muscle pain and, in rare cases, serious allergic reactions.
An allergic reaction to metformin is rare but possible. If you experience any signs or symptoms of an allergic reaction, seek immediate medical attention. Symptoms of an allergic reaction include swelling of the lips, mouth, throat, or tongue, rapid or difficulty breathing, skin, tongue, or lip discolouration, sudden confusion, drowsiness, or dizziness. In children, an allergic reaction may present as limpness or unresponsiveness. A rash that is swollen, raised, itchy, blistered, or peeling may accompany these symptoms.
Metformin may also cause muscle pain, which can be severe. If you experience muscle pain while taking metformin, it is important to consult your doctor or pharmacist. Muscle pain can be a symptom of lactic acidosis, a rare but serious condition that can be life-threatening. Lactic acidosis is characterised by severe and rapid-onset symptoms, including abdominal discomfort, decreased appetite, diarrhoea, fast or shallow breathing, general discomfort, muscle pain or cramping, and unusual sleepiness, tiredness, or weakness.
It is important to note that not all side effects of metformin require medical attention, and some may resolve on their own as your body adjusts to the medication. However, if you experience any severe or persistent side effects, including muscle pain or symptoms of an allergic reaction, consult your healthcare provider immediately. They may advise you to discontinue the medication and seek emergency medical care if necessary.
In summary, while metformin is generally safe and effective, it is crucial to be aware of potential side effects, including muscle pain and allergic reactions. Always follow the advice of your healthcare provider when taking any medication, and do not hesitate to seek medical advice if you have any concerns or experience any unusual symptoms.

Metformin may cause gastrointestinal issues
Metformin is a medication used to treat type 2 diabetes. It helps to control blood sugar levels by reducing the amount of glucose absorbed from food and produced by the liver, as well as increasing the body's response to insulin. While metformin is often well-tolerated, it can cause various side effects, including gastrointestinal issues.
Gastrointestinal side effects are common during the initiation of metformin therapy and often resolve spontaneously. These issues include nausea, vomiting, diarrhea, abdominal pain, and loss of appetite. To minimise gastrointestinal discomfort, it is recommended to take metformin with food. Increasing the dosage gradually over several weeks can also help reduce the chances of feeling sick. Additionally, staying hydrated by taking small, frequent sips of water is important to avoid dehydration, which can be a concern when experiencing vomiting or diarrhea.
Metformin may also cause vitamin B12 deficiency, especially with long-term use. This can lead to symptoms such as peripheral neuropathy, numbness or tingling in the feet and legs, and anemia. Therefore, it is advisable to include B12-rich foods in your diet, such as beef liver, clams, chicken, beef, eggs, dairy products, and fortified cereals. Regular monitoring of vitamin B12 levels is recommended, and supplements may be prescribed if levels are insufficient.
In rare cases, metformin can cause a serious condition called lactic acidosis, which requires immediate medical attention. Symptoms of lactic acidosis include abdominal discomfort, decreased appetite, diarrhea, fast or shallow breathing, severe muscle pain or cramping, and unusual sleepiness. Lactic acidosis is more likely to occur when there are other severe health problems present, such as a heart attack or kidney failure. It is important to inform your doctor if you have any underlying conditions or experience any of the mentioned symptoms.
