What Other Information Should I Know
Your doctor will tell you how to check your response to this medication by measuring your blood sugar levels at home. Follow these instructions carefully.
If you are taking the extended-release tablets, you may notice something that looks like a tablet in your stool. This is just the empty tablet shell, and this does not mean that you did not get your complete dose of medication.
You should always wear a diabetic identification bracelet to be sure you get proper treatment in an emergency.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.

Complications Of Metformin In Diabetic Nephropathy
Another important issue regarding metformin use concerns kidney transplant patients. Nondiabetic kidney transplant recipients are at risk for developing new onset diabetes after transplant, a common complication associated with kidney transplant that can affect allograft and patient survival.49 To prevent complications associated with diabetes, proper glycaemic control is imperative however, the extent of metformin use among kidney transplant recipients is currently uncertain. In 2008, Kurian et al.50 demonstrated that metformin was safe in 24 kidney transplant recipients for a mean duration of 16.4 months up to a maximum of 55 months.50 Although the study found no cases of LA, eGFR decreased in all patients. Patients with pre-existing diabetes experienced significant changes in eGFR. More recently, an observational study showed that 9.8% of kidney transplant recipients who filed at least one prescription for an antiglycaemic agent also had at least one claim for metformin or a metformin-containing agent.51 Metformin was associated with lower adjusted HR for both living donors and deceased donor allograft survival at 3 years post-transplant, and with lower mortality.

Controversial/unresolved Issues Areas For Future Research
There have been no randomized clinical trials to test the specific hypothesis that metformin is safe in patients with mild to moderate CKD. Randomized trials would help to better inform evidence-based guidelines. However, given the rarity of lactic acidosis in the setting of metformin therapy, a study would need to examine hundreds of thousands of patients for many years to demonstrate non-inferiority compared with other agents, which is clearly impractical. National patient registries might be a reasonable alternative. However, for regulatory bodies at this time, the best available evidence is limited to meta-analyses, retrospective studies, and smaller mechanistic investigations reported herein.

Are There Different Types Of Diabetes
The most common ones are Type 1 and Type 2. Type 1 diabetes usually occurs in children. It is also called juvenile onset diabetes mellitus or insulin-dependent diabetes mellitus. In this type, your pancreas does not make enough insulin and you have to take insulin injections for the rest of your life.
Type 2 diabetes, which is more common, usually occurs in people over 40 and is called adult-onset diabetes mellitus. It is also called non-insulin-dependent diabetes mellitus. In Type 2, your pancreas makes insulin, but your body does not use it properly. The high blood sugar level often can be controlled by following a diet and/or taking medication, although some patients must take insulin. Type 2 diabetes is particularly prevalent among African Americans, American Indians, Latin Americans, and Asian Americans.
Will Metformin Hurt Our Kidneys
Will metformin hurt our kidneys? This is a common question for diabetes patients. As we know, diabetes is one of the most common leading causes of kidney disease, the long-term uncontrolled high blood sugar will cause finally cause kidney disease. Metforimin is a common and effective western medicine for type 2 diabetes which can help control the high blood pressure, but some patients may be confused whether metformin will hurt kidneys or not.
Recently, a research shows that metformin will not cause kidney damage for people with normal kidney function, in turn it can help protect the kidneys. The metformin has the function of protecting kidneys by the increased levels of a molescule known as AMPK . The research concerned an adipokine, a hormone produced by fat cells, which is called adiponectin. Different from other substances produced by fat cells, adiponectin is good for people, which can help suppress inflammations and reduce the amount of protein in urine. Besides, the adiponectin can activate AMPD, and when the AMPD is stimulated, the kidney will stop leaking protein. In this aspect, we can find that metformin can help protect the kidney function for people who have healthy kidneys.
Besides, metformin can also cause side effects, such as gastrointestinal distress, which will affect peoples appetite. Patients can take metformin with meals, besides they can also take yogurt and milk thistle which can also remit their GI symptoms.

Current Guidelines And Future Implications
These studies highlight the lack of randomised clinical trials to test the specific hypothesis that metformin is safe in patients with mild to moderate CKD. Randomised trials would help to better inform evidence-based guidelines. Nevertheless, given the rarity of LA in the setting of metformin therapy, a study would need to examine hundreds of thousands of patients for many years to demonstrate noninferiority compared with other hypoglycaemic agents, which might not be feasible. National patient registries might be a reasonable alternative however, for regulatory bodies at this time, the best available evidence is limited to meta-analyses, retrospective studies, and smaller mechanistic investigations reported herein.
Other non-American guidelines considered the use of eGFR to determine the safety of metformin. The National Institute for Health and Care Excellence recommends using metformin with caution in patients58 for whom serum creatinine > 130 mol/L or eGFR < 45 mL/min. Doses should be lower and prescribed with increased frequency of monitoring. In patients already taking metformin, the drug should be discontinued if the serum creatinine > 150 mol/L or GFR < 30mL/min.
Can A Person With Diabetes Have A Kidney Transplant
Yes. Once you get a new kidney, you may need a higher dose of insulin. Your appetite will improve so your new kidney will break down insulin better than your injured one. You will use steroids to keep your body from rejecting your new kidney. If your new kidney fails, dialysis treatment can be started while you wait for another kidney.

What Are The Contraindications
We do not use metformin for patients with factors predisposing to lactic acidosis.
These predisposing factors for lactic acidosis/contraindications are:
Significantly impaired renal function Active or progressive liver disease Active alcohol use Unstable or acute heart failure. History of lactic acidosis during metformin therapy The patient comes in the hospital with low blood pressure problems.
Cancer is not a contra-indication for metformin.
The exact degree of kidney, heart, and liver function required for the safe use of metformin is uncertain. Improved clinical outcomes with metformin have been reported in observational studies of patients with diabetes and heart failure, mild kidney impairment , or chronic liver disease with hepatic impairment. Seventeen observational studies comparing regimens with and without metformin, metformin use showed a reduction in mortality rate among patients with heart failure, kidney impairment, or chronic liver disease. Besides, metformin use in patients with renal impairment or heart failure led to possible fewer heart failure readmissions.
Our approach to the administration of metformin:
For patients with an eGFR < 30, we do not prescribe metformin. When EGFR 45, we prescribe full dose. For patients with an eGFR of 30 to 44 and in the absence of active kidney, we do not use more than 1000 mg of metformin a day. On the other hand, lower doses of metformin may not produce the desired effect of glucose reduction.
Can Metformin Cause Kidney Problems
Actually, metformin is usually not the original cause of kidney problems. However, metformin is eliminated by the kidneys and when a patient has poor kidney function, the metformin can build up in the blood and cause a rare but serious condition called lactic acidosis. Lactic acidosis affects the chemistry balance of your blood and can lead to kidney failure and other organ failure. The risk of lactic acidosis is very low and most often occurs in patients with poor kidney function â so for most patients, the benefits of metformin outweigh the risks of treatment. Most doctors will regularly perform kidney function tests to make sure the kidney is working well in patients who are taking metformin. With that said, if you are taking metformin, contact your doctor immediately if you experience unexplained weakness, muscle pain, difficulty breathing, or increased drowsiness â these can be early signs of lactic acidosis. Also, if you are taking metformin and going to receive a radiocontrast dye study or have surgery, tell your doctors that you are taking metformin â in most cases, your doctor will instruct you to temporarily stop taking metformin during these procedures to help decrease the risk of lactic acidosis.

Glycemic Goal To Attain A1c ~70 %
Glycemic control is essential to delay or possibly prevent nephropathy. In general, the recommended target A1c for diabetes control by the ADA has been less than or around 7 % . The ADA advises both higher or stricter A1c goals for certain populations . AACE suggests a goal A1c of 6.5 % in healthy patients who are at low risk for hypoglycemia but also acknowledges the goals need to be individualized . The 2007 Kidney Disease Outcomes Quality Initiative guidelines for Diabetes and CKD endorse a target A1c of < 7.0 % but their updated 2012 guidelines instead recommend an A1c of ~7.0 % .
The ACCORD study showed higher risk of hypoglycemia and mortality in patients with type 2 diabetes treated with intensive glucose control , without any risk reduction on CVD. The increased mortality could not be attributed to hypoglycemia . In the ADVANCE trial, more intensive glycemic control showed no reduction in CVD. However, the intensive group had a 21 % reduction in nephropathy . The VADT study also showed no benefit on CVD risk with stricter glucose control .
The data clearly show that lowering A1c leads to benefit in regards to nephropathy. Benefits in A1c reduction are also seen on rates of retinopathy and neuropathy. However, the effect of lowering A1c is much less in regards to macrovascular disease. Thus, it is reasonable that a target A1c ~7.0 % offers an optimal risk to benefit ratio rather than a target that is considerably lower.
Hypoxia Inducible Factor 1
The hypoxia inducible factor pathway is an adaptive response to renal insult however, sustained HIF activation may promote renal fibrosis in CKD . HIF1 inhibition mitigates glomerular hypertrophy, mesangial expansion, matrix accumulation, and albuminuria excretion in type I diabetic OVE26 mice . HIF1 is a heterodimeric transcription factor that regulates oxygen homeostasis, which consists of the constitutively expressed HIF1 subunit and the oxygen-labile HIF1 subunit. Hypoxia prevents the proteasomal degradation of the HIF1 subunit, which then heterodimerizes with HIF1 to regulate the transcription of genes controlling erythropoiesis, angiogenesis, and nucleoside and energy metabolism . Aside from hypoxia, glucose overload , angiotensin II , and albuminuria also promote renal fibrosis by stabilizing HIF1. HIF1 modulates extracellular matrix turnover, activates fibrogenic factors such as tissue inhibitor of metalloproteinases and plasminogen activator inhibitor, and promotes EMT . Moreover, HIF1 can act synergistically with TGF1 .
Metformin suppresses tubular HIF1 stabilization and protects kidneys from renal injury in Zucker diabetic fatty rats independently of AMPK signaling. It attenuates mitochondrial respiration and thereby reduces cellular oxygen consumption, subsequently enhancing the proteasomal degradation of HIF1 . Notably, HIF1 promotes renal fibrosis in a cell type- and disease phase-specific manner .

What Is Chronic Kidney Disease
Kidney disease also known as nephropathy is a very common complication of persistently high blood sugar levels in people with diabetes. Approximately 50 percent of all kidney failure cases in the United States are associated with type 2 diabetes.
Diabetes-related kidney disease is defined by damage occurring largely in the blood vessels and nerve-endings in your kidney, impairing its ability to manage and properly filter waste in your bloodstream.
There are 5 stages of kidney disease, the final stage being end-stage renal failure which will lead to death if a patient doesnt receive serious intervention like a transplant or daily dialysis.
Fortunately, diligent blood sugar management can not only prevent CKD but can also prevent it from worsening after it has already developed.
This is where metformin comes in as a potentially doubly impactful treatment option to lower blood sugar levels and protect the kidneys from further damage as seen in this most recent study.

Change In Best Practice Treatment
Until now, the FDA has actually cautioned against prescribing higher doses of metformin to patients with kidney disease because of a potential increase in lactic acidosis, which would further stress the kidneys.
This new research suggests that patients in the earlier stages of kidney disease could benefit from metformin without seeing an increase in lactic acid levels.
Only one participant in the entire study experienced an event related to high levels of lactic acidosis directly related to metformin use
The findings are reassuring that the risk of lactic acidosis is very low even in stage 4 CKD, added the studys authors.
There is increasing evidence that treatment with metformin in patients with mild to moderate CKD is safe and may also confer a survival benefit, said expert Samira Bell, MB, a consultant nephrologist at the Renal Unit of Ninewells Hospital in Dundee, UK.
However, randomized controlled trial evidence is required before the widespread use of metformin in patients with eGFR < 30 mL/min/1.73m2 can be recommended.

Recommendations For Nephropathy Screening In Diabetes
Patients with diabetes should be screened on an annual basis for nephropathy. In individuals with type 1 diabetes, screening for nephropathy should start 5 years after diagnosis of diabetes since the onset of diabetes itself is usually known. It typically takes about 5 years for microvascular complications to develop. In patients with type 2 diabetes, screening should begin at initial diagnosis since the exact onset of diabetes is often unknown .
Diabetic nephropathy can be detected by the measurement of urine albumin or serum creatinine, and both tests should be performed at minimum annually those with abnormal levels should have repeat tests done sooner. The first stage of nephropathy is usually the onset of elevated urine albumin which predicts the development of CKD and a gradual decline in glomerular filtration rate . Some individuals with CKD, however, do not develop elevated urine albumin initially. It is therefore important that individuals have both blood and urine screening tests performed. Using both modalities allows for identification of more cases of nephropathy than using either test alone.
A Patients Experience With Metformin And Bathroom Emergencies:
Q. I was on metformin for years with no problem. Then my dose was increased, and I started to have colon spasms and extreme bathroom urgency.
The doctor prescribed meds to manage that, but this wasnt perfect. I started to stay home and skip a lot of activities.
My physician took me off metformin and the GI drugs, and now Im fine. Its much better not to worry about bathroom emergencies.
A. Digestive problems including diarrhea are not uncommon with metformin. The extended release formulation seems less likely to cause this problem. In addition, taking metformin with a meal may help.
