More coffee or tea keeps diabetes at bay

Sunday, May 23rd, 2010

Drinking more than four cups of a favourite beverage daily can cut the risk of developing type-2 diabetes by up to 40 percent, says a new study. People who consumed three to four cups of coffee a day had one-quarter lower risk of developing diabetes compared to non-coffee drinkers, said study leader Rachel Huxley, associate professor at The George Institute.

“The reduction in risk of developing diabetes was even greater, up to 40 percent, in those drinking more than six cups per day,” she said. “Interestingly, similar reductions in risk were observed for tea and decaffeinated beverages suggesting that any diabetes-sparing effect is not driven primarily through caffeine as previously thought,” Huxley added.

The study was based on the data from 18 previously completed research studies, providing a patient pool of 457,922 individuals. Results were consistent irrespective of variations in preparation, such as filtered versus unfiltered, cup size, cup strength and the addition of milk or sugar, said a George Institute release.

“Although it is too early to advocate for increased consumption of these beverages, identifying the active components of these beverages would potentially open up new therapeutic pathways for the primary prevention of diabetes,” Huxley said. Globally, there are approximately 250 million people with diabetes and that number is estimated to increase by 65 percent to reach 380 million in 2025.

What causes diabetes?

Monday, May 3rd, 2010

Diabetes (diabetes mellitus) is classed as a metabolism disorder. Metabolism refers to the way our bodies use digested food for energy and growth. Most of what we eat is broken down into glucose. Glucose is a form of sugar in the blood – it is the principal source of fuel for our bodies.

When our food is digested the glucose makes its way into our bloodstream. Our cells use the glucose for energy and growth. However, glucose cannot enter our cells without insulin being present – insulin makes it possible for our cells to take in the glucose.

Insulin is a hormone that is produced by the pancreas. After eating, the pancreas automatically releases an adequate quantity of insulin to move the glucose present in our blood into the cells, and lowers the blood sugar level.

A person with diabetes has a condition in which the quantity of glucose in the blood is too elevated (hyperglycemia). This is because the body either does not produce enough insulin, produces no insulin, or has cells that do not respond properly to the insulin the pancreas produces. This results in too much glucose building up in the blood. This excess blood glucose eventually passes out of the body in urine. So, even though the blood has plenty of glucose, the cells are not getting it for their essential energy and growth requirements.

Diabetes Treatments

All types of diabetes are treatable, but Type 1 and Type 2 diabetes last a lifetime; there is no known cure. The patient receives regular insulin, which became medically available in 1921. The treatment for a patient with Type 1 is mainly injected insulin, plus some dietary and exercise adherence.

Patients with Type 2 are usually treated with tablets, exercise and a special diet, but sometimes insulin injections are also required.

If diabetes is not adequately controlled the patient has a significantly higher risk of developing complications, such as hypoglycemia, ketoacidosis, and nonketotic hypersosmolar coma. Longer term complications could be cardiovascular disease, retinal damage, chronic kidney failure, nerve damage, poor healing of wounds, gangrene on the feet which may lead to amputation, and erectile dysfunction.

Symptoms of Diabetes

Wednesday, April 7th, 2010

People can often have diabetes and be completely unaware. The main reason for this is that the symptoms, when seen on their own, seem harmless. However, the earlier diabetes is diagnosed the greater the chances are that serious complications, which can result from having diabetes, can be avoided.

Here is a list of the most common diabetes symptoms:

* Frequent urination
Have you been going to the bathroom to urinate more often recently? Do you notice that you spend most of the day going to the toilet? When there is too much glucose (sugar) in your blood you will urinate more often. If your insulin is ineffective, or not there at all, your kidneys cannot filter the glucose back into the blood. The kidneys will take water from your blood in order to dilute the glucose – which in turn fills up your bladder.
* Disproportionate thirst
If you are urinating more than usual, you will need to replace that lost liquid. You will be drinking more than usual. Have you been drinking more than usual lately?
* Intense hunger
As the insulin in your blood is not working properly, or is not there at all, and your cells are not getting their energy, your body may react by trying to find more energy – food. You will become hungry.
* Weight gain
This might be the result of the above symptom (intense hunger).
* Unusual weight loss
This is more common among people with Diabetes Type 1. As your body is not making insulin it will seek out another energy source (the cells aren’t getting glucose). Muscle tissue and fat will be broken down for energy. As Type 1 is of a more sudden onset and Type 2 is much more gradual, weight loss is more noticeable with Type 1.
* Increased fatigue
If your insulin is not working properly, or is not there at all, glucose will not be entering your cells and providing them with energy. This will make you feel tired and listless.
* Irritability
Irritability can be due to your lack of energy.
* Blurred vision
This can be caused by tissue being pulled from your eye lenses. This affects your eyes’ ability to focus. With proper treatment this can be treated. There are severe cases where blindness or prolonged vision problems can occur.
* Cuts and bruises don’t heal properly or quickly
Do you find cuts and bruises take a much longer time than usual to heal? When there is more sugar (glucose) in your body, its ability to heal can be undermined.
* More skin and/or yeast infections
When there is more sugar in your body, its ability to recover from infections is affected. Women with diabetes find it especially difficult to recover from bladder and vaginal infections.
* Itchy skin
A feeling of itchiness on your skin is sometimes a symptom of diabetes.
* Gums are red and/or swollen – Gums pull away from teeth
If your gums are tender, red and/or swollen this could be a sign of diabetes. Your teeth could become loose as the gums pull away from them.
* Frequent gum disease/infection
As well as the previous gum symptoms, you may experience more frequent gum disease and/or gum infections.
* Sexual dysfunction among men
If you are over 50 and experience frequent or constant sexual dysfunction (erectile dysfunction), it could be a symptom of diabetes.
* Numbness or tingling, especially in your feet and hands
If there is too much sugar in your body your nerves could become damaged, as could the tiny blood vessels that feed those nerves. You may experience tingling and/or numbness in your hands and feet.
