Metformin is a widely used hypoglycemic drug in clinical practice, commonly prescribed to treat type 2 diabetes. While it is known to have anti-inflammatory, autophagy-regulating, and mitochondrial biogenesis-regulating effects, its specific mechanism of action in neuromuscular diseases is not yet fully understood. Metformin has been associated with various side effects, including gastrointestinal issues, vitamin B12 deficiency, and in rare cases, a serious allergic reaction. Some sources suggest that metformin may induce muscle atrophy and wasting, but the evidence is inconclusive. While metformin is generally considered beneficial for maintaining skeletal muscle function, its role in muscle stiffness specifically requires further exploration.

Metformin can cause muscle atrophy
Metformin is a drug that is used to treat high blood sugar levels caused by type 2 diabetes. It is the most widely prescribed anti-diabetic drug for patients with this condition. When used in combination with a healthy diet and exercise, metformin can help control blood sugar levels and improve insulin sensitivity.
However, the long-term use of metformin has been associated with several side effects, including those that affect muscle function. One of the more severe side effects is muscle atrophy, which involves the loss of muscle mass and quality. While the exact molecular mechanism of metformin's effect on muscles is not yet fully understood, studies have shown that metformin induces the expression of myostatin, a molecule that regulates muscle volume and triggers the phosphorylation of AMPK. This increase in myostatin expression is believed to be controlled by activated p-AMPK, which enables the binding of FoxO3a and myostatin, leading to muscle wasting.
In vitro studies have also provided evidence for the role of HDAC6 in this process. HDAC6 binds to FoxO3a and may regulate muscle atrophy by increasing FoxO3a expression. Furthermore, metformin's impact on skeletal muscle mass has been observed in clinical trials. One study found that metformin negatively affected the increase in skeletal muscle mass and strength in patients who underwent progressive resistance exercise training.
Additionally, metformin has been linked to a decrease in sex hormone levels, which can contribute to the degradation of skeletal muscle mass and an increased risk of sarcopenia, a condition characterised by a decline in skeletal muscle mass and function due to aging. However, it is important to note that the relationship between metformin and skeletal muscle disorders is still being explored, and further research is needed to fully understand its impact on muscle atrophy and other muscle-related conditions.

Metformin can induce muscle wasting
Metformin is a medication used to treat type 2 diabetes. It is often the first medicine prescribed to patients with this condition. The drug helps to lower blood sugar levels in three ways: by reducing glucose production in the liver, lowering insulin resistance, and decreasing glucose absorption in the intestines.
While metformin is an effective treatment for type 2 diabetes, it can cause several side effects, including muscle pain and cramping. In rare cases, it can also induce a serious condition called lactic acidosis, which causes severe muscle pain and cramping, among other symptoms. However, the relationship between metformin and muscle wasting is more complex and not yet fully understood.
Some studies have suggested that metformin may induce muscle atrophy or wasting through the transcriptional regulation of myostatin via HDAC6 and FoxO3a. Specifically, metformin increases the levels of p-AMPK and myostatin, a molecule associated with muscle atrophy. This increase in myostatin expression may be related to HDAC6's deacetylation activity, as HDAC6 binds to FoxO3a, potentially regulating acetylated FoxO3a expression and increasing FoxO3a expression overall.
However, other studies have found that metformin may negatively affect muscle response during resistance training in older individuals, despite its anti-inflammatory properties. The effect of metformin on muscle function remains controversial, and more research is needed to fully understand the relationship between metformin and muscle wasting, as well as the role of dose-dependent efficacy.
It is important to note that muscle stiffness or wasting can have various causes, and metformin may not be the only contributing factor. If you are experiencing muscle stiffness or wasting and are concerned about potential side effects of metformin or any other medication, consult your doctor or healthcare provider for personalized advice and guidance.

Metformin may cause lactic acidosis
Metformin is a drug used to treat type 2 diabetes by controlling blood sugar levels. It is available as a tablet, an extended-release tablet, and a solution (liquid) to be taken by mouth. While metformin is beneficial in managing blood sugar levels, it may cause certain side effects in some individuals. One of the rare but serious side effects associated with metformin is lactic acidosis.
Lactic acidosis is a life-threatening condition that can occur due to too much metformin in the body. It is characterised by a rapid onset of severe symptoms, which may include abdominal discomfort, decreased appetite, diarrhea, fast or shallow breathing, a general feeling of discomfort, severe muscle pain or cramping, and unusual sleepiness, tiredness, or weakness. These symptoms typically arise when other severe health issues unrelated to the medication are present, such as a heart attack or kidney failure.
The risk of developing lactic acidosis while taking metformin is higher in individuals with certain underlying conditions. For example, those with kidney disease, a history of heart attack, stroke, diabetic ketoacidosis, coma, or heart or liver disease may be more susceptible. Additionally, taking specific medications alongside metformin can further increase the risk of lactic acidosis. These medications include acetazolamide (Diamox), dichlorphenamide (Keveyis), methazolamide, topiramate (Topamax), and zonisamide (Zonegran).
If symptoms indicative of lactic acidosis develop, it is imperative to seek immediate emergency medical assistance. Furthermore, individuals taking metformin should be vigilant about monitoring their kidney function and overall health. Regular visits to the doctor and laboratory tests can help identify any adverse effects early on and guide appropriate adjustments to the medication regimen.

Metformin can cause vitamin B12 deficiency
Metformin is a medicine used to treat type 2 diabetes. It is in a class of drugs called biguanides and helps to control blood glucose levels. Metformin is also used to prevent type 2 diabetes in patients at high risk of developing it.
Metformin has been found to cause vitamin B12 deficiency, especially in patients who have been taking it for a long time or at a higher dose. The mechanism behind this is not yet fully understood, but it is thought to involve altered intestinal motility, bacterial overgrowth, and reduced uptake of vitamin B12 within the small intestine. Metformin blocks the absorption of vitamin B12, potentially by interfering with the calcium-dependent binding of the intrinsic factor vitamin B12 complex to the cubam receptor in the terminal ileum.
Vitamin B12 deficiency can lead to several health issues, including anaemia and neuropathy. Neuropathy, or nerve damage, is a known complication of diabetes, and vitamin B12 deficiency caused by metformin may worsen this. Peripheral neuropathy can cause distal symmetrical and autonomic neuropathy, including cardiac denervation, which is associated with increased cardiac arrhythmias, cardiac events, and mortality.
It is recommended that patients taking metformin be periodically monitored for vitamin B12 deficiency, especially if they have been taking the medication for over five years. If a patient presents with symptoms of vitamin B12 deficiency, such as extreme tiredness, a sore and red tongue, pins and needles, or pale or yellow skin, they should seek medical advice. Blood tests can determine whether these symptoms are caused by low vitamin B12 levels, diabetes, or other health issues.
If vitamin B12 deficiency is diagnosed, it can be treated with vitamin B12 supplements, while the patient continues taking metformin. In some cases, metformin withdrawal may be necessary.

Metformin can cause allergic reactions
Metformin is a drug used to treat type 2 diabetes. It is typically administered in the form of a tablet, an extended-release tablet, or a solution taken orally. Metformin helps to control blood glucose levels by decreasing the amount of glucose absorbed from food and produced by the liver. It also increases the body's response to insulin, a hormone that regulates blood sugar.
Like all medications, metformin can cause side effects, although not everyone experiences them. Some common side effects include nausea, vomiting, abdominal pain, loss of appetite, and vitamin B12 deficiency. In rare cases, metformin can also cause a serious allergic reaction known as anaphylaxis.
- Swelling of the lips, mouth, throat, or tongue
- Difficulty breathing, including rapid breathing, wheezing, or a feeling of choking or gasping for air
- A tight feeling in the throat or difficulty swallowing
- Skin, tongue, or lips turning blue, grey, or pale
- Sudden confusion, drowsiness, or dizziness
- In children, a limp or floppy body, lack of responsiveness, or difficulty lifting the head or focusing
- A rash that is swollen, raised, itchy, blistered, or peeling
If you experience any of these symptoms after taking metformin, seek immediate medical attention. Anaphylaxis is a life-threatening condition that requires prompt treatment in a hospital setting. It is important to inform your doctor or healthcare provider if you have any known allergies or experience any adverse reactions to medications.
