Metformin is the most widely prescribed anti-diabetic drug for patients with type 2 diabetes. While it is known to produce a glucose-lowering effect, it may also cause several side effects, including muscle cramps and aches. Some patients have reported experiencing leg and foot cramps, while others have noticed reduced muscle pain after starting metformin. Research on the association between metformin and musculoskeletal pain is ongoing, with some studies suggesting it may have a protective effect against pain.

Metformin may reduce musculoskeletal pain
While some people have reported experiencing muscle aches and pains after starting to take Metformin, research suggests that the drug may reduce musculoskeletal pain.
A cross-sectional study with 21,889 individuals from the UK Biobank found that participants with type 2 diabetes who took metformin were less likely to report back, knee, neck/shoulder, and multisite musculoskeletal pain than those not taking the drug. The study also found that metformin may have a protective effect for musculoskeletal pain, which appears to be stronger among women than men.
The findings suggest that metformin decreases the odds of reporting chronic back pain in people who are obese, over 60 years old, and engage in lower levels of physical activity. The study also found that females taking metformin who reported lower levels of physical activity or were older than 60 years of age had lower odds of reporting chronic back pain than those not taking the drug.
Another study published in the European Journal of Pain in February 2021 included nearly 22,000 people in the United Kingdom with type 2 diabetes. The study found that participants using metformin had lower odds of musculoskeletal pain in the back, knee, and shoulder/neck area.
While the exact mechanism is not yet fully understood, there is growing evidence of metformin's anti-inflammatory effects and its potential to reduce pain.

Metformin can cause muscle atrophy
Metformin is the most widely prescribed anti-diabetic drug for patients with type 2 diabetes. While it is known to produce a glucose-lowering effect, it can also cause several side effects, including those that affect muscle function.
Some studies have found that metformin can induce muscle atrophy by regulating myostatin, a key molecule that controls muscle volume and triggers AMPK phosphorylation. This up-regulation of myostatin is controlled by activated p-AMPK, which enables binding between FoxO3a and myostatin. FoxO3a binds to the putative binding site of myostatin by directly activating its expression. Because HDAC6 also binds to FoxO3a, it is believed that HDAC6-mediated myostatin up-regulation is related to its deacetylation activity.
Additionally, metformin has been found to negatively impact the hypertrophic response to resistance training in healthy older individuals. This is contrary to what was expected, as metformin reduces inflammation, which should have a positive impact on muscle response.
However, the effect of metformin on muscles is still controversial, and more research is needed to understand its mechanism in muscle atrophy. It is also important to note that individual body chemistry varies, and while some people experience muscle cramps and pain when taking metformin, others may not experience any adverse effects.

Metformin may induce muscle wasting
Metformin is the most widely prescribed anti-diabetic drug for patients with type 2 diabetes. While it is known to produce a glucose-lowering effect, it may also increase the levels of p-AMPK and myostatin, a muscle atrophy-related molecule.
Several studies have investigated the association between metformin and musculoskeletal pain. One study, including 22,000 people in the United Kingdom with type 2 diabetes, found that those taking metformin had lower odds of reporting chronic multisite musculoskeletal pain, especially in the back, knee, and shoulder/neck areas. Another study published in BMC Public Health in May 2021 reported similar findings, suggesting that metformin may provide a protective effect against musculoskeletal pain.
However, the effect of metformin on muscle wasting is still unclear and controversial. A recent in vitro study found that metformin induced the expression of myostatin through the activation of p-AMPK, which is involved in regulating muscle volume. This suggests that metformin may contribute to muscle wasting by up-regulating myostatin expression.
While the molecular mechanism of metformin's effect on muscles requires further investigation, some individuals taking metformin have reported experiencing muscle cramps and pain. It is important to note that everyone's body chemistry is unique, and while some people tolerate metformin well, others may experience side effects like muscle aches, fatigue, and brain fog, especially when adjusting to the medication.

Metformin may cause muscle cramps
Metformin is the most widely prescribed anti-diabetic drug for patients with type 2 diabetes. While it is known to produce a glucose-lowering effect, it may also cause muscle cramps.
Several studies have investigated the association between metformin and musculoskeletal pain. One study, including 22,000 people in the United Kingdom with type 2 diabetes, found that participants using metformin had lower odds of reporting musculoskeletal pain in the back, knee, and shoulder/neck area. However, the same results were not observed for those experiencing chronic hip pain. Another study published in the journal BMC Public Health in May 2021 reported that metformin may provide a protective effect against musculoskeletal pain, which was more pronounced in women than in men.
Despite these findings, some individuals taking metformin have reported experiencing muscle cramps and pain. In an online forum, a user shared that they started experiencing severe calf cramps and muscle pain after beginning treatment with metformin. Another user mentioned experiencing leg and foot cramps at night after being diagnosed with type 2 diabetes and starting metformin.
It is important to note that everyone's body chemistry is unique, and side effects from medications can vary from person to person. While some individuals experience muscle cramps with metformin, others have found relief from cramps while taking the medication. It is always advisable to consult with a healthcare professional when experiencing any adverse effects from medication.

Metformin may cause muscle pain
Metformin is the most widely prescribed anti-diabetic drug for patients with type 2 diabetes. It is known to produce a glucose-lowering effect and improve insulin sensitivity. However, its long-term administration can cause several side effects, including those that affect muscle function.
Some people who take metformin have reported experiencing muscle pain and cramps. For instance, one person taking 500 mg of metformin a day reported having achy muscles and chest and chronic fatigue. Another person taking 1000 mg twice a day reported having major muscle cramps and pain when their dosage was increased to 750 mg twice a day.
Research has also investigated the association between metformin and musculoskeletal pain. One cross-sectional study with 21,889 participants from the UK Biobank found that people with diabetes taking metformin were less likely to report back, knee, neck/shoulder, and multisite musculoskeletal pain than those not taking the drug. However, the study did not find that metformin provided relief for those experiencing chronic hip pain.
Another study published in the European Journal of Pain in February 2021 included nearly 22,000 people in the United Kingdom with type 2 diabetes. The study found that participants using metformin had lower odds of musculoskeletal pain in the back, knee, and shoulder/neck area.
While these studies suggest that metformin may help reduce musculoskeletal pain, it is important to note that the molecular mechanism of metformin in muscle is not yet fully understood. Some studies have found that metformin can induce muscle atrophy and wasting through the up-regulation of myostatin, a molecule that regulates muscle volume and triggers the phosphorylation of AMPK.
Overall, while metformin may provide a protective effect against musculoskeletal pain, more research is needed to fully understand its effects on muscle function.
