Diabetes problems

Saturday, April 12th, 2008

Diabetes is a condition when the level of glucose in our blood increases up to such an extent that it damages different parts of our body organ. Normally, the level of glucose is controlled by a hormone called Insulin, secreted by the beta cells of pancreas. Now, there are two types of diabetes – type I and type II. In the former, there is reduced secretion of insulin as the pancreas gland is damaged due to some reason. In the case of type II diabetes, the is normal or higher level of insulin, but the glucose level still remain increased as the body tissues becomes refractory to the hormone.

Excess amount of blood glucose can harm almost every part of our body. The notable are heart, kidney, eyes, skin and blood vessels. There is increase level of cholesterol also. The combined effect of increased blood glucose and cholesterol help in the formation of plaques (thrombus) inside the blood vessel – leading to heart attacks (when inside the vessels supplying blood to the heart muscle) and stroke (cerebral thromboembolism – when that of the brain). But there are certain things that will help us to prevent or at least slow down the problems caused by diabetes.

Diabetes is a silent killer. Everybody can be affected. Type I diabetes occurs in the younger age group. So, in this category, diabetes problems may not float for years. But the damage still goes on inside our body. Type II diabetes develops in the adult. By the time the disease is diagnosed, it may have been caused some overt manifestations. Either way, maintaining a normal blood glucose and cholesterol level can prevent diabetes problems.

Now the most important question comes. What is the normal blood glues level? According to ADA (American Diabetes Association), a patient will be stamped diabetic when the blood glucose level increases beyond to –

In empty stomach before meals -> 90mg/dl to 130mg/dl of blood

After 1-2 hours from starting a major meal -> less than 180mg/dl of blood

Any measurement above the given parameter is unacceptable. You can check the level by any good quality blood glucose meter or from a nearby laboratory.

High blood pressure and diabetes go hand in hand. So, periodically check your blood pressure from qualified personnel.

You can do a lot of things to prevent diabetes and its complications. This disease is familial. If there is somebody from your close relatives suffering from the disease, watch yourself and check your blood glucose level periodically after six months. Consult your doctor and ask for a low dose aspirin. This will prevent formation of any plaque inside the blood vessels.

You should have a complete eye check up every year. Diabetes is a notorious disease that affects the tiny blood vessels of the retina. And if these vessels are damaged, you are sure to have blindness. Let the ophthalmologist examine your eye by instillation of some medicine to dilate your pupil. You may have vision problem for a day, but do not bother. This examination is highly essential to see the inside of your eye.

Your diet should be optimum. Avoidance of excess carbohydrate and fat is needed. According to modern way of treatment, there is no need to stop taking carbohydrates. The only thing that has to be kept in mind is your daily total calorie intake. Include fresh green leafy vegetables in your diet. Regular exercise is a must.

Following the instructions will help you to prevent diabetic problems.

Can stress accelerate aging?

Tuesday, March 18th, 2008

All of us must have felt the curse of stress at some part of our life. Both the older and the comparatively younger persons are forced to face difficult situations and learning to coexist with them. While the elderly persons are to deal with the physical and financial problems, the younger generation is facing the difficulties in their studies, friends, emotional relationships and workplaces. Luckily, we learn to cope up with the difficulties that are the effect of stress with due course of time. But during the last couple of decades in our life, the natural defense mechanism of our body fails to perform in an effective way.

We can spot the relation between how we live and how we die. The earlier in our life we are confronted by stress, the scenario becomes worse. The stress will leave a negative impact upon the way we become older and how fact that occurs.

In earlier years, the belief was that the animals those who have lower heart rate will live longer. No more that is considered reliable. Modern hypothesis is that it is because of the long term effects to various stressors and stress hormones which are responsible for accelerating the aging process.

A specific case is very much interesting and has a worth for separate study. It is the relation of body and the secretion of glucocorticoid hormones during stress. The hypothalamus present in the central nervous system regulates the secretion of glucocorticoids from the adrenal gland by releasing a hormone – Corticotropin Releasing Hormone (CRH). CRH consequently commands the adrenal gland to release the glucocorticoid hormones.

How does the hypothalamus decide when there is enough glucocorticoid in the blood pool? Actually it is regulated by the mechanisms present in our body for controlling the secretion of all the hormones. The hypothalamus controls the secretion of CRH and consequently the glucocorticoids using a feedback mechanism. Hypothalamus in the aged people can not work as it should be. This is the reason the higher level of glucorticoids in the blood even the person is not suffering from any kind of stress.

What may be the reason of the malfunctioning of the feedback system? The answer is not obvious, but the most likely reason is the increased level of glucorticoids during the period of chronic stress. Again it may be concluded that a prolonged exposure to glucocorticoids will result in Hippocampal damage, which may lead to more glucorticoids being released in the blood stream.

Hippocampal damage leads to another disease called – Alzheimer’s disease. This is undoubtedly one of those extremely debilitating diseases known to man. Hippocampus is a part of the brain that is a vital area for storage and retrieving memories. This is the reason; the persons suffering from full blown Alzheimer’s disease can not recall any of his long term or short term memory.

Experts have proved that the chronic stress can accelerate the rate of aging. So it is imperative to say that everybody should control the stress as far as possible.

You can do some relaxation techniques. You can do a course upon yoga and meditation. These two ways have an immense potentiality for relieving stress. Regular exercise is another effective approach. Fix a time from your schedule everyday that is suitable for you to exercise. Regular workout helps to wash out the surplus stressors and stress hormones from your body. Proper planning in life is essential to reduce stress. You must bring laugh in your life.

It is a normal occurrence to lose around 100 strands a day. If you are experiencing more than this, you may be suffering from excessive hair loss that can lead to baldness. (more…)
