Diabetic Kidney Damage May Be Reversible

Kidney Stone Diet Ppt

Diabetes is the most common cause of kidney failure. Until recently, it was thought that once a diabetic leaks protein into his urine, the kidneys are damaged and can never heal. However, kidneys damaged by diabetes have healed after high blood pressure has returned to normal and after pancreatic transplants. Blood pressure medications called Ace inhibitors and angiotensin receptor blockers have also healed diabetes-damaged kidneys. The kidney is supposed to allow urine, but not protein, to pass through its filters. Doctors used to tell diabetics that since damaged kidneys never heal, they could never take metformin, an important drug for treating diabetes. Now all diabetics should be told to get their diabetes under control by avoiding refined carbohydrate , losing weight, exercising, stopping smoking, and getting their HBA1C blood tests to normal. If their kidneys stop spilling protein, they may be able to take metformin again. 1) Remission and regression of diabetic nephropathy. Hypertension Research, 2003, Vol 26, Iss 7, pp 515-519.

What Conditions Are Treated With Metformin

An estimated ten percent of Americans have diabetes, which exists in two types: Type 1 and Type 2. Type 1 diabetes, or juvenile diabetes, is defined by the bodys failure to produce enough insulin, while Type 2 diabetes results from insulin resistance.

Most people with diabetes have Type 2 diabetes, which is heavily influenced by lifestyle factors such as weight, diet, and activity level. People with both forms of diabetes cannot properly utilize the glucose, or sugar, in the foods we consume and turn it into energy.

In a healthy body, our digestive systems break down the food we eat into glucose, which is released into the bloodstream. As glucose enters the bloodstream,the levels of sugar in the blood rise, causing the pancreas to start to release insulin. Insulin is a hormone that is responsible for directing the body to begin converting the sugar in the blood into energy.

In people with Type 2 diabetes, the directions given by insulin are ignored, so levels of sugar in the blood remain high for a prolonged period of time, causing potentially serious complications.

Metformin helps to increase the bodys sensitivity to insulin, which allows glucose in the blood to be used for energy. Although some people are able to control their Type 2 diabetes through lifestyle changes alone, others require medications like metformin in order to avoid dangerous health effects and complications.

Different Types Of Metformin

Metformin comes as 2 different types of tablet: standard-release tablets and slow-release tablets.

Standard-release tablets release metformin into your body quickly. You may need to take them several times a day depending on your dose.

Slow-release tablets dissolve slowly so you do not have to take them as often. One dose is usually enough, and you’ll take it with your evening meal.

Your doctor or pharmacist will explain what type of metformin tablets you’re on and how to take them.

Metformin is also available as a liquid for children and people who find it difficult to swallow tablets.

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.
