Learn about the potential side effect of low blood sugar when taking metformin, a commonly prescribed medication for diabetes. Discover the symptoms, causes, and how to manage low blood sugar while using metformin.
Can metformin cause low blood sugar?
Metformin is a commonly prescribed medication for the treatment of type 2 diabetes. It works by reducing the amount of glucose produced by the liver and increasing the sensitivity of muscle cells to insulin. While metformin is generally considered safe and well-tolerated, some people may experience low blood sugar levels as a side effect.
Low blood sugar, also known as hypoglycemia, occurs when the level of glucose in the blood drops below normal. Symptoms of low blood sugar can include dizziness, sweating, confusion, and fatigue. In severe cases, it can even lead to unconsciousness or seizures. It is important for individuals taking metformin to be aware of the potential risk of low blood sugar and to take appropriate steps to manage it.
One of the reasons metformin can cause low blood sugar is that it enhances the action of insulin in the body. This can lead to a greater uptake of glucose by muscle cells, which can deplete the amount of glucose available in the blood. Additionally, metformin can suppress the liver’s production of glucose, further contributing to low blood sugar levels.
It is worth noting that the risk of low blood sugar with metformin is generally higher in individuals who also take other diabetes medications that can lower blood sugar, such as insulin or sulfonylureas. These medications work by stimulating the release of insulin from the pancreas, which can increase the risk of hypoglycemia when combined with metformin.
What is metformin?
Metformin is a medication commonly used to treat type 2 diabetes. It belongs to a class of drugs known as biguanides, which work by decreasing the amount of glucose produced by the liver and improving the body’s response to insulin. Metformin is typically taken orally and is available in both immediate-release and extended-release formulations.
In addition to its role in managing diabetes, metformin has also been studied for its potential benefits in other conditions such as polycystic ovary syndrome (PCOS) and obesity. It has been shown to help regulate menstrual cycles and improve fertility in women with PCOS, and may also aid in weight loss.

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’s cells become resistant to the effects of insulin, leading to elevated blood sugar levels. Metformin helps lower blood sugar by improving insulin sensitivity and decreasing the amount of glucose produced by the liver.
Common side effects of metformin
Like any medication, metformin can cause side effects. Some common side effects include:
- Stomach upset or diarrhea
- Nausea or vomiting
- Metallic taste in the mouth
- Loss of appetite
- Headache
- Dizziness
These side effects are usually mild and go away on their own as the body adjusts to the medication. However, if the side effects persist or become severe, it is important to talk to a healthcare provider.
Conclusion
Metformin is a commonly prescribed medication for the management of type 2 diabetes. It works by decreasing the amount of glucose produced by the liver and improving the body’s response to insulin. Metformin has been shown to be effective in controlling blood sugar levels and may also have additional benefits in conditions such as PCOS and obesity. Like any medication, metformin can cause side effects, but these are usually mild and transient. If you have any concerns or questions about metformin, it is important to speak with a healthcare provider.
How does metformin work?
Metformin is a medication commonly prescribed to treat 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 increasing the sensitivity of muscle and fat cells to insulin.
When you eat, your body breaks down carbohydrates into glucose, which is then released into your bloodstream. In people with type 2 diabetes, the liver produces too much glucose and the body’s cells become resistant to the effects of insulin, a hormone that helps regulate blood sugar levels. This leads to high blood sugar levels, which can cause a variety of health problems.
Metformin works by reducing the amount of glucose produced by the liver. It does this by activating an enzyme called AMP-activated protein kinase (AMPK), which inhibits the production of glucose in the liver and promotes the uptake of glucose by muscle cells.
In addition to reducing liver glucose production, metformin also increases the sensitivity of muscle and fat cells to insulin. This means that these cells are better able to take up and use glucose from the bloodstream, leading to lower blood sugar levels.
Overall, the primary mechanisms of action of metformin include:
- Decreasing liver glucose production
- Promoting the uptake of glucose by muscle cells
- Increasing the sensitivity of muscle and fat cells to insulin
By targeting these key processes involved in blood sugar regulation, metformin helps to improve glycemic control and reduce the risk of complications associated with type 2 diabetes.
Can metformin cause low blood sugar?
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. While metformin is generally well-tolerated, there is a potential risk of developing low blood sugar, also known as hypoglycemia.
Hypoglycemia occurs when blood sugar levels drop below normal levels, typically below 70 mg/dL. This can happen when there is too much insulin in the body or when the body’s glucose production is reduced. Metformin does not directly cause low blood sugar, but it can increase the risk of hypoglycemia when used in combination with other diabetes medications or if not taken as prescribed.
Risk factors for low blood sugar with metformin
Several factors can increase the risk of developing low blood sugar while taking metformin:
- Taking metformin in combination with other diabetes medications that can lower blood sugar levels
