Metformin is an oral prescription anti-diabetic drug that was created especially for people with Type 2 diabetes. It is marketed under the trade names Glucophage, Fortamet, and Riomet. That example, if a diabetic is not required to have an insulin shot every day.
For many years, metformin has been used to treat diabetes and diseases that are associated to it. Metformin is still the top choice for treating Type 2 diabetes, even with the development of newer medications. It is also being used to treat other disorders related to insulin resistance, such as PCOS.
Prior to Metformin
French lilac (Galega officinalis) has been used for generations to alleviate the symptoms of diabetes mellitus. However, the active component wasn’t isolated or discovered until the last century.
Despite being too hazardous to be used in the long term to manage diabetes, this compound—a single guanidine ring—led to the invention of metformin, one of the safest and most popular antidiabetic drugs available.
Metformin is a member of the biguanides, a class of pharmaceuticals made up of two connected guanidine rings. It is only now that we are starting to understand how it works, even though it has been used to treat diabetes for at least thirty years; the precise mechanisms of action are still mostly unknown.
How Metformin Operates
Without raising the blood level of insulin, metformin helps lower plasma glucose levels and the liver’s synthesis of glucose. Metformin differs from other glucose-lowering medications of the sulfonylurea class, such as glyburide (Micronase; Diabeta) and glipizide (Glucotrol), due to its distinct effect on blood insulin levels.
Metformin improves the uptake of glucose from the bloodstream by making muscle and fat cells more sensitive to insulin absorption. Glucose is metabolized by insulin, however insulin and glucose remain in the bloodstream instead of being transferred to body cells if cells are not sensitized to insulin. This kind of long-term situation will lead to the elevated blood glucose levels associated with Type 2 Diabetes.
However, we are aware that metformin affects glucose metabolism in a variety of ways. These actions result in decreased gluconeogenesis (the production of glucose from non-carbohydrate sources) by the liver and increased insulin sensitivity in tissues including muscle and liver.
The overall effect of these and a few other activities is a reduction in glucose levels. However, blood glucose levels do not typically drop below normal due to the euglycemic effect of metformin.

Resistance To Insulin And Metformin
As metformin fights insulin resistance, it is a very successful treatment for type 2 diabetes. Furthermore, metformin is a highly effective treatment for polycystic ovarian syndrome, since it improves symptoms and increases ovulation chance by up to eight times, hence significantly boosting fertility. It seems safe to use when expecting as well.
For patients with insulin resistance and related disorders such as PCOS, Type 2 diabetes, and metabolic syndrome, metformin has unquestionably demonstrated therapeutic advantages. Check out Metformin And Its Benefits for Various Diseases, published in Frontiers in Endocrinology (2020) for a comprehensive list of illnesses for which it is beneficial.
Metformin Lowers Risks to Health
It has been demonstrated that metformin is especially helpful in lowering the risk of death from diabetes complications among patients who are overweight or obese, as these individuals are more likely to develop diabetes.
Metformin is a first-line treatment for diabetes, however it has not been widely administered to diabetic patients who already have kidney or cardiovascular disease due to concerns about its possible safety in these patients.
Renal and cardiovascular disorders are recognized consequences of diabetes. The health and well-being of the approximately 24 million patients with diabetes in the US alone, as well as the hundreds of thousands of diabetic patients who have already developed kidney and cardiovascular disease, depend heavily on the results of the clinical research study that is the subject of this discussion.
This published study reports on the outcomes of the large Reduction of Atherothrombosis for Continued Health (REACH) Study, which included 19,691 patients with confirmed diabetes.
It was published in the 2006 issues of the American Heart Journal and the Archives of Internal Medicine. (The enormous number of patient volunteers in the REACH Study has been monitored by the researchers from their enrollment in the study between December 2003 and December 2004.)
The results of smaller earlier clinical investigations are validated by the results of this extremely large prospective public health study. In this trial, taking metformin instead of other diabetes drugs (or no diabetes medication at all) significantly reduced the risk of death for diabetic individuals with cardiovascular disease during the study.
Compared to the diabetic individuals in this trial who did not take metformin, the metformin-using patients had a mortality risk that was 24% lower.
Metformin use was linked to a 31% decrease in death from all causes among individuals with congestive heart failure, a condition that was previously thought to preclude the use of the medication. Furthermore, this study suggests that metformin may be beneficial for people with additional medical issues that have been previously assumed to preclude metformin treatment for diabetes.
Metformin reduced mortality risk by 23% for diabetic patients with cardiovascular disease who were over 65. Conversely, patients with reduced kidney function (estimated creatinine clearance of 30 to 60 ml/minute) saw an astounding 36% reduction in mortality risk from metformin.
Metformin Lowers Diabetes Complications
Metformin lowers the risk of blindness and other diabetic complications, including kidney and heart problems. The FDA has approved metformin since 1994. It has been effective in reducing blood sugar levels without taking undue measures.
Hypoglycemia, which can result from a blood glucose level that is too low, is characterized by symptoms that can include headache, moderate disorientation, sweating, dizziness, aberrant behavior, loss of consciousness, seizure, and coma.
Metformin Side Effects
Because of this, taking Metformin might occasionally cause side symptoms that resemble hypoglycemia. This can occur in those who have somehow developed an intolerance to it, leading to lactic acidosis, a potentially fatal illness.
If you experience any of the following signs of lactic acidosis, you should seek emergency medical attention right away: weakness, drowsiness, sluggish heartbeat, feeling chilly, muscle soreness, dyspnea, dizziness, and fainting. If you have poor liver, kidney, or congestive heart failure functioning, you are more likely to develop lactic acidosis.
Lactic acidosis is more likely to occur in older persons. Metformin with a delayed release should not be administered to anyone under the age of 17. In any event, it should not be given in any form to children younger than ten.
Additional adverse effects could include hives, breathing difficulties, or allergic reaction signs like swelling of the lips, tongue, neck, or cheeks. Along with rapid weight gain, swelling, flu-like symptoms, body pains, chills, fever, headache, weakness, and even mild nausea, you might also feel shortness of breath even with light effort. You may also get muscle soreness, gas, diarrhea, vomiting, and stomach pain while using metformin.
Do not take Metformin if you have a history of liver, kidney, or heart illness without your doctor’s express consent. Diabetic ketoacidosis is the overproduction of glucose caused by the breakdown of muscle and fat tissues in the body. If you are in this condition, contact your doctor to receive insulin treatment.
Therefore, the majority of these side effects can be managed by beginning treatment with extremely low dosages and gradually raising the dosage until the intended outcomes are reached. Metformin is better absorbed when taken with food, which reduces the amount of the drug that remains in the digestive tract and can irritate and cause diarrhea.
By taking the drug in smaller dosages, such as 500 mg every eight hours, rather than all at once, nausea may be reduced. With this issue, the more recent sustained release formulations might be helpful as well. It’s crucial to remember that all of the negative effects of metformin typically get better with time.
Lactic acidosis represents yet another, more significant, albeit far less common concern. This rarely happens unless there are underlying issues such heart failure, liver or kidney illness, or if the daily amount of metformin taken is higher than the current adult advised maximum of 2550 mg.
Lactic acidosis manifests as weakness, soreness in the muscles, breathing difficulties, abdominal pain, lightheadedness, and a sluggish heartbeat. Treatment for this extremely severe condition is required right away. Thankfully, it is uncommon and infrequently observed.
The Metformin Effects Lives
Metformin continues to have life-changing potential that is rarely discussed in medical texts. It reduces carbohydrate cravings and eases the persistent fatigue that individuals with insulin resistance feel. Additionally, it makes losing weight much simpler for those who have never been able to drop a few pounds and keep them off.
Metformin is a medication that is both safe and helpful in improving the quantity and quality of life for those unlucky individuals who suffer from insulin resistance.
Disclaimer: Before starting any kind of treatment, it is always advisable to speak with your doctor. Find out which of your other prescription and over-the-counter medications, as well as vitamins and herbs, will affect your blood glucose levels and which may interact negatively with metformin.
Speak with your physician or another trained healthcare provider if you require any additional information regarding Metformin.
