Metformin and the Liver
The majority of people think diabetes comes from pancreas damage, due to autoimmune problems or insulin resistance. However for many people diagnosed “Type 2,” the huge issues remain in the liver. What are these problems, and what can we do about them?
Metformin’s Effect on the Liver
First, some basic physiology you might currently understand. The liver is among the most complicated organs in the body, and perhaps the least understood. It plays a big role in handling sugars and starches, making certain our bodies have adequate fuel to function. When there’s a great deal of sugar in the system, it stores some of the excess in a storage type of carbohydrate called glycogen. When blood glucose levels get low, as in times of hunger or in the evening, it converts some of the glycogen to glucose and makes it offered for the body to use.
Easy to state, however how does the liver understand what to do when to do it? Researchers have actually found a “molecular switch” called CRTC2 that manages this procedure. When the CRTC2 switch is on, the liver pours sugar into the system. When there’s sufficient sugar flowing, CRTC2 must be turned off. The turnoff signal is thought to be insulin. This may be an oversimplification, though.
Inning accordance with Salk Institute researchers quoted on RxPG news, “In numerous patients with type II diabetes, CRTC2 not responds to rising insulin levels, and as a result, the liver imitates a sugar factory on overtime, churning out glucose [day and night], even when blood sugar levels are high.” Because of this, the “average” individual with Type 2 diabetes has 3 times the normal rate of glucose production by the liver, according to a Diabetes Care short article.
AFDiabetics reader Jim brought the entire “dripping liver” phenomenon to my attention. He has regularly published about his own battles with soaring blood sugars that were not managed by 75/25 insulin, pioglitazone (trademark name Actos), nateglinide (Starlix), and glyburide (Micronase, Diabeta, Glynase, Prestab). All the medicines were overwhelmed by his liver’s dumping glucose.
The best tool medication has actually discovered for controlling the liver is metformin. Metformin has actually been known for decades; it has been the first-line oral diabetes medicine in the United States because the 90’s. However up until recently, we really have not comprehended how it works, so it has usually not been used to best advantage.
Metformin avoids the liver from discarding more glucose into the blood. Scientists used to believe it worked by telling CRTC2 to cooperate with insulin (to puts it simply, decreasing insulin resistance.) But new research studies have found that metformin really works by bypassing CRTC2 and straight informing the liver cells to hold the sugar.
So if your CRTC2 switch is busted, you need some metformin in your blood at the majority of times, to avoid the liver’s disposing glucose. Jim discovered this one night when he forgot his dinnertime metformin and took it at bedtime rather. In the early morning, he had very little dawn effect; his early morning sugars were better. Working with his doctor, he found out that taking 500 milligrams of metformin at 10 PM and another 500 milligrams at midnight kept his sugars down until 5:30 AM.
It seems that for individuals whose dripping livers are the main factor in their sugar levels, taking 500 milligrams of metformin four or 5 times a day may be maximum. However everyone’s different, and it takes some work (with your doctor) to discover what pattern works best for you.
Metformin takes a number of hours to totally soak up, and lasts about five hours in many people. (Half-life in the body has to do with 6 hours.) There is likewise an extended release kind that can be taken once or twice a day.

What causes leaky livers in the first location is not really known. It seems that people with fatty livers may be up to 5 times as likely to establish diabetes, so liver fat, which is loosely related to abdominal fat, may belong to the story. However thin individuals can have leaky livers, too, so there’s more to it.
It might help to learn when your liver tends to dump sugars. This may require regular tracking for a while. Jim has a continuous glucose monitor, which allowed him to get his regime right. Inning accordance with him, if his sugar goes low, or his metformin level goes low, or sometimes after eating (for some unknown reason), his liver will dump glucose into his bloodstream, as he can see on his monitor. The only thing that stops it is having enough metformin in his system.
Individuals without diabetes in some cases take metformin for weight reduction or for conditions like polycystic ovary syndrome (PCOS). It’s one of the best, most economical and most effective chemical medications ever developed.
When the dosage is too low, nevertheless, it may not appear to work at all. Bottom line is that many individuals with diabetes may not be getting adequate metformin or not getting it at the right times. You might be among them, particularly if you have a dawn result, specifically if you’re currently on a basal insulin.
There is a lot more to learn and state about these subjects, but I want to speak with you first. Does any of this ring a bell for you? What have been your experiences?
