Long-term side effects Taking metformin can cause vitamin B12 deficiency if you take it for a long time. This can make you feel very tired, breathless and faint, so your doctor may check the vitamin B12 level in your blood. If your vitamin B12 levels become too low, vitamin B12 supplements will help.
How long to take it for. Treatment for diabetes is usually for life. But if your kidneys are not working properly, your doctor will tell you to stop taking metformin and switch you to a different medicine. Do not stop taking metformin without talking to your doctor.
Based on these focus groups, the researchers found that three main factors affected how doctors prescribed metformin: concerns about when to start the drug, concerns about the drug's known risks, and whether procedures were in place to notice and deal with any adverse reactions caused by the drug.
Physiologically, metformin acts directly or indirectly on the liver to lower glucose production, and acts on the gut to increase glucose utilisation, increase GLP-1 and alter the microbiome.
Clinically apparent liver injury from metformin is very rare, fewer than a dozen cases having been described in the literature despite widespread use of this agent for several decades. The liver injury usually appears after 1 to 8 weeks, typically with symptoms of weakness and fatigue followed by jaundice.
If your kidneys don't function properly, there's concern that metformin can build up in your system and cause a condition called lactic acidosis. Lactic acidosis is when there's a dangerous amount of lactic acid in the body.
GLP – 1 Receptor Agonists (Bydureon, Byetta, Ozempic, Adlyxin, Rybelsus, Trulicity, and Victoza) Usage: This is another alternative to metformin. This comes in both oral and injection forms. GLP-1 receptor agonists are safe for kidney patients as it reduces risks of kidney damage and also support heart health.
High-Fiber Foods
Researchers posit that exceeding 30 grams of fiber in a day may lower metformin levels in the body due to the fact that fiber binds to the drug and reduces its efficacy. (9) So it may be best to avoid high-fiber foods like oatmeal, chickpeas, avocado, berries, peas, beans, and chia seeds.
The current drug labeling strongly recommends against metformin use in some patients whose kidneys do not work normally because use of metformin in these patients can increase the risk of developing a serious and potentially deadly condition called lactic acidosis, in which too much lactic acid builds up in the blood.
Metformin has a black box warning for lactic acidosis — a condition where too much lactic acid builds up in the blood. It's a serious problem and can lead to death. If you experience these symptoms, seek medical attention right away.
Metformin may rarely cause a serious, life-threatening condition called lactic acidosis. Tell your doctor if you have kidney disease. Your doctor will probably tell you not to take metformin.
If your diabetes remains hard to manage even after you begin taking metformin, or you cannot tolerate metformin or do not want to take it, that's when a GLP-1RA or SGLT2i might come in. Studies have shown that both medications are safe and effective at lowering blood glucose when compared to a placebo.
The Mechanism of GlucoRedi:
The fact that GlucoRedi doesn't interfere with other metabolic processes sets it apart from other blood glucose supplements and makes it one of the best natural alternatives to metformin.
Making positive lifestyle changes such as eating a well-balanced diet, exercising regularly and getting down to a healthy weight (and maintaining it) are the key to possibly reversing or managing type 2 diabetes.
There are some risks if you decide to stop taking metformin on your own. For example, your blood glucose levels may not be controlled. Over time, this can increase the risk of diabetes complications such as vision problems, nerve damage, and heart disease. Talk to your healthcare provider before stopping metformin.
Official answer. Most experts consider metformin to be the safest medicine for type 2 diabetes because it has been used for many decades, is effective, affordable, and safe. Metformin is recommended as a first-line treatment for type 2 diabetes by the American Diabetes Association (ADA).
Metformin may exert part of hypoglycemic effects by altering the gut microbiota in ways that maintain the integrity of the intestinal barrier, promote the production of short-chain fatty acids (SCFAs), regulate bile acid metabolism, and improve glucose homeostasis.
If you stop taking metformin abruptly, your health may suffer. You may experience side effects such as higher blood sugars, an increased A1c, and even weight gain. Over time, higher blood sugar levels can lead to diabetes complications, including: Retinopathy and blindness.
