Metformin is a widely used drug with a wide range of applications. For instance, if you have Type 2 diabetes, this is probably the first prescription your doctor will recommend to help you manage your blood sugar. It may also be suggested if you have prediabetes and lifestyle modifications like exercise haven’t been effective in controlling your blood sugar. It is being researched for applications besides diabetes, such as cancer prevention and delaying the effects of aging.
What is the Purpose of Metformin?
There are various types of medication. It aids persons with Type 2 diabetes who are 10 years of age and older in controlling blood sugar levels as an oral solution and an immediate-release tablet. Also available, but only for adults, is an extended-release formulation that is FDA-approved for the same use.
Other blood sugar-lowering drugs, such as Jentadueto (linagliptin/metformin) and Invokamet (canagliflozin/metformin), are also available in conjunction with this drug. It is prescribed for a variety of different medical disorders in addition to diabetes. All of them are off-label usage, which implies the FDA has not endorsed them.
How is Diabetes Treated with Metformin?
It aids in lowering both fasting and post-meal blood sugar levels. These three are the principal ways it accomplishes this:
- The body becomes more insulin-sensitive as a result. Your body produces the hormone insulin, which transports sugar from your blood to your cells and provides them with the energy they require to function. Cells don’t react as well to insulin when there is an excess of sugar in the blood, which leads to further accumulation of sugar in the blood. Insulin resistance is a condition that can result in diabetes. Because it reduces insulin resistance, cells can absorb and utilize sugar more efficiently.
- Absorption of sugar is decreased. Your diet is a significant way that sugar enters your body. Sugar and other nutrients are absorbed into your bloodstream when food reaches your intestines. Less sugar enters your bloodstream as a result of this drug’s ability to reduce the amount of sugar that is absorbed by your intestines.
- Reduced sugar production results. You consume meals that contain sugar, but did you know that your body also makes sugar on its own? The liver is where most of this occurs. The liver produces less sugar after using it.
How Much Does Metformin Reduce Blood Glucose Levels?
According to studies, this drug by itself can reduce hemoglobin A1C (AIC) by an average of 1%. You can get an idea of your average blood sugar levels over three months by measuring your A1C through a blood test. An A1C of less than 7% is the target for the majority of diabetes sufferers.
Your doctor may advise adding other medications that can lower blood sugar if you’re currently taking it but aren’t exactly where you want to be.
What are Metformin’s Typical Adverse Effects?
This drug’s adverse effects, which typically involve stomach discomfort, are quite minor when compared to those other diabetes treatments. These consist of:
- Gas
- Uneasy stomach
- Nausea
- Vomiting
- Diarrhea
- Cramping
These negative consequences can be minimized by:
- Metformin dosage should be progressively increased after starting low. This provides time for your body to adjust to the new medicine.
- Eating when taking it. You might feel less queasy or nauseous as a result.
- Your body gradually releases metformin ER throughout it. Compared to taking it that is intended for immediate release (IR), this may be gentler for your digestive system.
What Distinguishes Metformin from Other Diabetes Medications?
In contrast to some other diabetic medications, it does not raise the amount of insulin your body produces. A drug that increases insulin production may be required if your body doesn’t produce enough of it. However, taking this kind of medication increases your risk of hypoglycemia, or low blood sugar. When used alone, it does not significantly increase your risk of low blood sugar.
Another reason it differs from other diabetic medications is that it typically prevents weight gain, unlike other diabetes medications. The possibility that it may aid in weight loss is one of the reasons why many medical professionals favor it. Losing weight is frequently advised to treat diabetes and maintain stable blood sugar levels.
What Other Uses are Being Researched for Metformin?
Metformin, a drug primarily used to treat type 2 diabetes, is being researched for several potential off-label uses and health benefits beyond its approved indication:
Cancer Prevention and Treatment
Numerous studies suggest that this drug may have anti-cancer properties and could potentially reduce cancer incidence and mortality in patients with and without diabetes. It has shown promise in preventing growth, survival, and metastasis of tumor cells across various cancers, including breast, prostate, colorectal, endometrial, and melanoma.
Cardiovascular Disease
It appears to have cardioprotective effects, reducing the risk of cardiovascular disease and mortality in diabetic patients. It may also benefit non-diabetic patients by improving endothelial function, reducing coronary plaque progression, and attenuating heart failure.
Ageing and Longevity
Some animal studies indicate this drug may increase lifespan, with effects similar to caloric restriction. While human studies have not conclusively demonstrated increased lifespan, it has been shown to improve age-related diseases like type 2 diabetes, cardiovascular disease, and cognitive impairment, which could potentially extend lifespan. The Targeting Aging with this drug (TAME) trial aims to investigate metformin’s ability to delay the onset of age-related diseases and reduce morbidity
Who Should Avoid Using Metformin?
While metformin is one of the most widely prescribed medications for managing type 2 diabetes, there are specific situations where its use may not be appropriate. Recent research has further clarified certain conditions and risk factors that warrant caution or avoidance of metformin use:
- Type 1 Diabetes: this drug is not recommended for individuals with type 1 diabetes. Type 1 diabetes is characterized by the body’s inability to produce insulin, and metformin works by enhancing insulin sensitivity and decreasing glucose production in the liver, which is ineffective for type 1 diabetics. Insulin therapy remains the primary treatment. Recent guidelines reaffirm that this drug does not replace insulin in type 1 diabetes and should not be used as a substitute.
- Metformin Allergy Symptoms: Although rare, some individuals may experience allergic reactions to metformin, such as rash, itching, or difficulty breathing. New research highlights that while hypersensitivity to this drug is uncommon, those with a history of drug allergies should be cautious. For individuals who have experienced symptoms of metformin allergy, alternative medications such as SGLT2 inhibitors or GLP-1 receptor agonists may be more suitable options.
- Liver Disease: Metformin should be avoided in individuals with certain liver conditions, particularly advanced liver disease or cirrhosis. The liver plays a crucial role in the metabolism of lactic acid, and in individuals with liver dysfunction, metformin use can increase the risk of lactic acidosis. A 2023 study confirmed that metformin is contraindicated in patients with severe liver impairment (such as cirrhosis or chronic hepatitis) but may still be cautiously used in patients with mild to moderate liver disease under strict medical supervision.
- Diabetes-Related Ketoacidosis: Individuals with diabetes-related ketoacidosis (DKA) should avoid metformin. DKA occurs when the body produces excess ketones due to the lack of insulin, leading to a dangerous buildup of acid in the blood. Since this drug does not directly address insulin deficiency, it is ineffective and potentially harmful in DKA cases. A recent review emphasized that immediate insulin therapy is required to manage DKA, making this drug inappropriate in such situations.
Additional Factors to Consider
Recent research has identified other conditions where the use of metformin may need to be reconsidered:
- Severe Kidney Disease: As metformin is primarily eliminated by the kidneys, its use in individuals with severe kidney impairment or end-stage renal disease (ESRD) can increase the risk of lactic acidosis. A 2022 update from the American Diabetes Association (ADA) clarified that metformin should generally be avoided in individuals with an estimated glomerular filtration rate (eGFR) below 30 mL/min/1.73m². For those with moderate kidney impairment (eGFR between 30-45 mL/min/1.73m²), lower doses may be used, but kidney function should be closely monitored.
- Heart Failure: Metformin has long been a subject of debate for use in patients with heart failure. Recent studies have found that while metformin may provide cardiovascular benefits for some patients with stable heart failure, it should be avoided in those with unstable or acute heart failure, particularly if they are at risk of renal dysfunction. A 2023 meta-analysis concluded that patients with severe heart failure should use metformin cautiously, with regular monitoring of both cardiac and renal function.
- Pregnancy and Breastfeeding: Although metformin is increasingly being studied for use in managing gestational diabetes, pregnant or breastfeeding individuals should consult their healthcare provider before using it. A 2024 review suggests that while metformin may be safe in pregnancy under medical supervision, it crosses the placenta and is excreted in breast milk, so careful consideration is needed, especially in the early stages of pregnancy.
Consultation with a Healthcare Provider
Choosing the right diabetes medication depends on a variety of personal factors, including medical history, lifestyle, and current health conditions. It’s crucial to have an open discussion with a healthcare provider to determine whether metformin is the best option for you. New guidelines emphasize personalized treatment plans, considering recent studies that show tailored approaches can significantly improve diabetes management outcomes.
If you have any of the conditions mentioned above, your doctor may suggest alternative medications or combinations of treatments to better suit your needs while minimizing the risk of adverse effects.
What Other Hazards Can Metformin Use Cause?
Here are some other hazards that can be caused by metformin use:
- This is a rare but serious condition that can occur when too much lactic acid builds up in the blood. Symptoms of lactic acidosis include abdominal pain, nausea, vomiting, shortness of breath, and muscle pain. If you experience any of these symptoms, you should seek medical attention immediately.
- This is a condition that occurs when blood sugar levels fall too low. Symptoms of hypoglycemia include sweating, shakiness, dizziness, confusion, and headache. If you experience any of these symptoms, you should eat or drink something sugary right away.
- Metformin can rarely cause liver problems. Symptoms of liver problems include yellowing of the skin or eyes, dark urine, nausea, vomiting, and loss of appetite. If you experience any of these symptoms, you should stop taking metformin and see your doctor right away.
- Metformin can also rarely cause kidney problems. Symptoms of kidney problemsinclude decreased urine output, swelling in the feet or ankles, and high blood pressure. If you have any of these symptoms, you should tell your doctor.
It is important to talk to your doctor about the risks and benefits of metformin before starting treatment. Metformin is a safe and effective medication for many people with diabetes, but it is important to be aware of the potential side effects and hazards.
Here are some additional tips for staying safe while taking metformin:
- Take it exactly as prescribed by your doctor.
- Do not take more metformin than prescribed.
- Do not take it if you have kidney or liver problems.
- Talk to your doctor before taking it if you are pregnant or breastfeeding.
- Monitor your blood sugar levels regularly while taking it.
- Report any side effects to your doctor right away.
In conclusion, it plays a pivotal role in the management of diabetes, specifically type 2 diabetes. As a widely prescribed medication, it serves a vital purpose in helping individuals maintain healthy blood sugar levels and reduce the risk of complications associated with diabetes.
The primary function of it is to improve insulin sensitivity and reduce the production of glucose in the liver. By doing so, it effectively lowers blood sugar levels and helps control hyperglycemia. Additionally, It aids in weight management, as it can contribute to modest weight loss in individuals with diabetes.
It is important to note that Metformin is not a standalone treatment for diabetes. It is often prescribed alongside other lifestyle modifications, such as a healthy diet and regular physical activity. Combining these interventions can lead to better glucose control and overall diabetes management.
