Key Takeaways

• Ozempic^® (semaglutide) and metformin are both prescription medications used to manage blood sugar levels in individuals with type 2 diabetes ^[1].

• Semaglutide is a brand-name drug, while metformin is available as a generic medication ^[1].

• Both drugs are effective in controlling blood sugar levels, but semaglutide has shown more significant results in weight reduction compared to metformin ^[2].

• Semaglutide belongs to the class of drugs called incretin mimetics or GLP-1 receptor agonists, which stimulate insulin release and slow down gastric emptying ^[2].

• Metformin is a biguanide that works by controlling glucose production in the liver and reducing sugar absorption in the intestines ^[2].

• It's generally safe to use semaglutide and metformin together, and doctors often prescribe this combination for better blood sugar management ^[1].

‍

What Is Semaglutide?

Semaglutide (the active ingredient in Ozempic^® and Wegovy^®) is a medicine that falls under a group of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists [4]. It copies the GLP-1 hormone, which the gut releases after eating [5]. This medicine has an influence on blood sugar control and weight management.

Semaglutide plays several roles in the body:

1. Blood Sugar Regulation: Semaglutide helps the pancreas release the right amount of insulin when blood sugar levels are high. This has an impact on controlling glucose levels [6].

2. Appetite Suppression: Semaglutide targets brain centers that control appetite after eating. This may help to reduce food intake [4].

3. Delayed Gastric Emptying: It has an effect on the speed at which the stomach empties, making people feel full for longer [4].

‍

Semaglutide comes in different forms and has different brand names:

• Ozempic®: This helps manage type 2 diabetes and lowers the risk of heart problems in grown-ups with type 2 diabetes and heart disease [6].

• Wegovy®: Doctors prescribe this to control weight in adults who weigh too much or have obesity [6].

‍

You need a medical consultation and prescription from a doctor to get compounded semaglutide, and it's essential to understand semaglutide dosages and guidelines. 

Clinical studies have demonstrated that semaglutide has an impact on weight loss and weight maintenance. To get the best results, you should use semaglutide along with a healthy diet and exercise plan [6].

‍

What Is Metformin?

Metformin is a common drug that doctors prescribe to treat type 2 diabetes and gestational diabetes [8]. For more than 50 years, this medicine has played a role in managing diabetes, helping patients keep their blood sugar in check [9].

Metformin has an influence on the body's insulin response and lowers the amount of glucose the liver makes and that the gut absorbs [8]. This insulin sensitizer holds back the body's glucose production by cutting down gluconeogenesis and changing glycogenolysis [10].

One of the main advantages of metformin lies in its capacity to reduce blood sugar levels without boosting insulin production [10]. This distinct feature distinguishes it from other diabetes medications and lowers the chance of hypoglycemia, which makes it a more secure choice for many patients.

You can find metformin in different forms, such as tablets, liquid, and powder sachets that you can mix into a drink [8]. Doctors prescribe it when diet and exercise alone don't manage to control blood sugar levels.

Apart from its main role in treating diabetes, metformin shows potential in other health fields. While metformin is FDA-approved for the treatment of type 2 diabetes, it is also sometimes prescribed off-label for managing symptoms of polycystic ovary syndrome (PCOS). However, this use is not FDA-approved and should be considered only under a healthcare provider's supervision. [8].

Off-label use of medications should always be guided by a healthcare professional to ensure safety and appropriateness.

Metformin has an association with less weight gain when compared to insulin and sulfonylureas. Patients who used metformin for ten years gained about one kg. In contrast, those who took glibenclamide gained three kg, and insulin users put on six kg [10].

‍

What Are The Benefits Of Semaglutide?

Benefit #1: Significant Weight Loss

Clinical studies have shown that semaglutide can lead to significant weight loss when used as part of a comprehensive treatment plan that includes diet and exercise. In some studies, participants lost up to 15% of their body weight [11]. A study looked at 2,000 overweight adults. After 68 weeks, half of those taking semaglutide lost 15% of their weight, and a third shed 20% [5]. This beats the 2.4% weight loss seen in people who just changed their habits [5]. 

Individual results may vary, and weight loss should be pursued under the guidance of a healthcare provider to ensure safety and effectiveness.

‍

Benefit #2: Better Metabolic Health

Semaglutide has an influence on metabolic health that goes beyond weight loss. It helps control blood sugar and lowers the chance of heart disease [11]. Research shows that semaglutide can cut the risk of serious heart problems, like heart attacks and strokes, by 26% in diabetics and 20% in non-diabetics [12]. On top of that, semaglutide seems to guard kidney health, dropping the odds of major kidney issues by 24% compared to a placebo [13].

‍

Benefit #3: Control of Blood Sugar and Less Hunger

Semaglutide, first created to treat type 2 diabetes, works well to control blood sugar levels. It copies the GLP-1 hormone, which makes the body produce insulin and slows down digestion [11]. This process helps manage blood glucose and reduces hunger, making it easier for people to control how much they eat [11]. Studies show that semaglutide can lower the diabetes marker hemoglobin A1C by up to 2 percentage points. More patients reach the treatment goal of less than 7% A1C with semaglutide compared to other drugs [12].
‍

What Are The Cons Of Semaglutide?

Con #1: Stomach Problems

People who take semaglutide often have stomach problems. Tests show that up to 20% of type 2 diabetes patients on semaglutide feel sick to their stomach [14]. This number goes up for those who use it to lose weight. Other usual side effects include throwing up, having loose stools, and feeling blocked up. About 9% of diabetes patients and 30% of weight loss patients had loose stools during tests [14]. These effects tend to get worse with higher doses. This is why doctors increase the amount over several months.

‍

Con #2: Chance of Major Side Effects

While generally well-tolerated, semaglutide can cause side effects, some of which may be serious, such as pancreatitis, gallbladder disease, and potential kidney issues. It is important to discuss these risks with your healthcare provider.

The occurrence and severity of side effects vary by individual. Always consult with your healthcare provider to understand the risks and benefits specific to your situation. 

It might cause pancreatitis, gallbladder disease, and kidney problems if bad nausea and vomiting lead to dehydration [14]. The FDA has put out a boxed warning about the chance of thyroid C-cell tumors [14]. 

‍

Con #3: Weight Comes Back After Stopping

One problem with semaglutide is that people might gain weight again when they stop taking it. Those who quit semaglutide often put back on a lot of the weight they'd lost [15]. This means that to keep the weight off, you might need to take it for a longer period of time. It shows that semaglutide should be part of a bigger long-term plan to manage weight, not just a quick fix.
‍

The Upsides About Metformin

Upside #1: Controls Blood Sugar Well

Metformin has been key to managing diabetes for more than 60 years because it can lower plasma glucose levels so well [16]. It has an impact on hepatic glucose production through AMPK-dependent and independent pathways [16]. Metformin also makes it easier for skeletal muscles to take in glucose and causes GLP-1 to be released, which helps to bring blood sugar levels down even more [16].

‍

Upside #2: Weight Management

Metformin has an influence on weight control. The Diabetes Prevention Program (DPP) found that people who took metformin lost about 2.1 kg over 2.8 years [17]. This weight drop lasted for a long period of time, with people keeping off around 2.5 kg after ten years [17]. A study in the real world showed even better results. Metformin users dropped 5.8 kg on average, while those not taking it gained 0.8 kg [17].

‍

Upside #3: More Health Perks Besides Diabetes

Metformin has benefits that go beyond managing diabetes. Research shows it might lower the chances of getting cancer, heart disease, and dementia [18]. Metformin can also help to control polycystic ovary syndrome (PCOS) and stop weight gain linked to antipsychotic drugs. Early studies hint that metformin could slow down aging and help people live longer, maybe by making insulin work better and acting as an antioxidant [18].

‍

‍

The Downsides Of Metformin

‍

Downside #1: Gastrointestinal Side Effects

Metformin users often have digestive issues. They might feel sick, throw up, get diarrhea, have stomach pain, or lose their appetite [19]. These problems usually show up when people start taking the medicine, but they tend to go away on their own [19]. To help avoid these issues, doctors suggest taking metformin with food and increasing the amount over a few weeks [19].

‍

Downside #2: Risk of Lactic Acidosis

Lactic acidosis, while uncommon, has an impact on metformin users as a serious potential side effect [20]. This condition happens when lactic acid accumulates in the blood, which leads to symptoms like feeling unwell, muscle pain, trouble breathing, and stomach discomfort [20]. Patients with kidney or liver problems, people over 65, or those undergoing certain medical procedures face a higher risk [20]. 

‍

Downside #3: Vitamin B12 Deficiency

Long-term metformin use has an effect on vitamin B12 levels, often leading to deficiency [19]. This deficiency can trigger symptoms such as tiredness, weak muscles, and eyesight issues [19]. Patients on metformin need to check their vitamin B12 levels regularly, especially those with a higher chance of becoming deficient [19]. If the levels drop too low, taking vitamin B12 supplements might be necessary to avoid problems [19].

‍

Metformin vs Semaglutide: Key Differences

Semaglutide and metformin treat type 2 diabetes. Semaglutide belongs to incretin mimetics or GLP-1 receptor agonists. It copies incretin hormones to release insulin and slow down stomach emptying [21]. This helps control blood sugar and reduce weight. Metformin is a biguanide. It makes insulin work better by controlling how much sugar the liver makes and cutting down sugar absorption in the gut [21].

‍

Both drugs can have side effects such as stomach problems like feeling sick, throwing up, and having loose stools [22]. But they don't work the same for losing weight. Metformin helps people lose a more conservative amount of weight, while semaglutide shows more significant results. Studies found that semaglutide led to an average weight drop of 14.9% from where people started, compared to 2.4% with a placebo [21].

‍

Semaglutide offers more benefits than just helping with diabetes. Doctors can prescribe it to lower the chances of serious heart problems in adults who have both type 2 diabetes and heart disease [22]. Metformin, while used for diabetes, also has other uses. Doctors sometimes prescribe it for problems like diabetes during pregnancy and PCOS, even though it's not approved for these [22].

‍

Metformin vs Semaglutide: Choosing The Right Fit For You?

When we look at metformin and semaglutide, we see that both drugs work well to control type 2 diabetes, but they do this in different ways and offer other benefits, too. The American Diabetes Association thinks of metformin as the preferred option for treating diabetes. It can lower hemoglobin A1C levels in just three months [22]. Metformin helps to make insulin work better and keeps the liver from making too much glucose [21].

‍

Semaglutide is a GLP-1 receptor agonist that copies incretin hormones to trigger insulin release and slow down stomach emptying [21]. This causes blood sugar control and weight loss. Clinical trials showed that semaglutide led to an average weight drop of 14.9% from the starting point, while the placebo resulted in a 2.4% decrease [21].

‍

While metformin can lead to slight weight loss, semaglutide has a more significant impact on weight reduction [22]. Research shows that taking semaglutide causes people with diabetes to lose about four to six percent of their weight on average. For those without diabetes, the weight loss is even greater [22].

‍

For patients with type 2 diabetes who also need help to manage their weight, semaglutide (sold as Ozempic^®) can treat both issues at once [22]. Semaglutide also costs more than metformin [21].

‍

Ultimately, the choice between metformin and semaglutide should be based on a comprehensive evaluation of your medical condition, treatment goals, and financial considerations, guided by your healthcare provider's expertise.

‍

Decisions about medication should always be made in consultation with a healthcare provider, who can provide tailored advice based on your individual health needs.
