Warning !! Knowing Hypertension Now or…??!!
- hypertension
Hypertension is the medical term for high blood pressure. During the course of a day, a person’s blood pressure continually rises and falls. However, when blood pressure constantly stays at 140/90 mm hg or higher, a person is considered to have hypertension. Hypertension can be caused by risk factors that you can and cannot change.
Other factors that have been associated with essential hypertension include obesity, diabetes, stress, insufficient intake of potassium, calcium, and magnesium, lack of physical activity, and chronic alcohol consumption.
The cause of essential hypertension is unknown, although lifestyle factors such as obesity, sedentary lifestyle, and excessive alcohol or salt intake contribute to the condition. The link between salt and high blood pressure is especially compelling. The majority of all people with high blood pressure are “salt sensitive,” meaning that anything more than the minimal bodily need for salt is too much for them and increases their blood pressure.
Hypertension is a rare blood vessel disorder of the lung in which the pressure in the pulmonary artery (the blood vessel that leads from the heart to the lungs) rises above normal levels and may become life threatening. Consistently high blood pressure causes the heart to work harder than it should and can damage the coronary arteries, the brain, the kidneys, and the eyes As blood travels through your body, it presses against the walls of the blood vessels. If your vessels become narrowed, your heart has to pump harder to maintain circulation, thus exerting more pressure against the vessel walls. This increased workload makes your heart larger and more inefficient. Blood pressure is the pressure the blood exerts against the blood vessel walls as the heart pumps. The pressure increases when the heart contracts and pushes blood into the vessels and lowers when the heart relaxes, but there’s always a certain amount of pressure in the arteries. Blood pressure is driven by two physical forces, the one from the heart as it pumps blood into the arteries and through the circulatory system, and the other from the arteries as they resist this blood flow.
Eventually, this high pressure will increase your risk of developing heart disease and stroke.
Hypertension is a condition that describes when the pulmonary arteries (the vessels that carry blood from the heart to the lungs) narrow, become blocked or damaged so they cannot carry as much blood. Unfortunately, hypertension often has no symptoms, and can only be diagnosed through regular blood pressure readings taken by a health care professional.
Once detected, hypertension is usually controllable.

Hyperglycemia

Knowing Hyperglicemia and what is the risk if not be prevented ?
Hyperglycemia is a major cause of many of the complications that happen to people who have diabetes. The two main reasons for having hyperglycemia are poor blood glucose control and getting sick. When you were first diagnosed with diabetes, you probably had hyperglycemia-and in fact, your blood glucose level may have been much higher than 200 mg/dl. Normal blood sugar levels are between 60-110 mg/dl (normal values may vary from laboratory to laboratory). If you have a fasting blood sugar level of between 110 and 125 mg/dl, you are diagnosed as having impaired glucose tolerance. This is a strong risk factor for developing diabetes
hyperglycemic
If you have any two blood sugar readings over 200mg/dl, you also may be diagnosed with diabetes.
High blood glucose happens when the body has too little, or not enough, insulin or when the body can’t use insulin properly. Low insulin levels prevent the body from converting our primary energy source glucose into glycogen. The body’s ability to convert glucose into glycogen and back into glucose is common in order to maintain homeostasis. Our bodies utilize as much sugar as possible for energy following a meal. however, in states of rest, the body stores that glucose into glycogen so that it can be used in the future when the body is deprived or starved of glucose. Hyperglycemia prevents the glucose-glycogen conversion and allows sugar to circulate the blood more so than normal even with the body at rest. When there is not enough insulin, the body cannot use glucose for fuel. These fats produce ketones when they are broken down. The body tries to get rid of the extra ketones through the urine. But if there are too many, they build up in the bloodstream causing ketoacidosis. The symptoms of ketoacidosis usually develop slowly.
In some people, stress hyperglycemia may indicate a reduced insulin secretory capacity or a reduced sensitivity, and is sometimes the first clue to incipient diabetes. Also, Hyperglycemia is a risk factor for early death and morbidity in extremely low birth-weight infants. It is a serious problem in diabetes.
The best way to prevent hyperglycemia is by through healthy food choices, exercising, and taking your medications as prescribed by your health care provider. Hyperglycemia can cause serious health problems if left untreated. Too much sugar in the bloodstream for long periods of time can cause damage to the vessels that supply blood to vital organs, which can increase the risk of heart disease and stroke, kidney disease, vision problems, and nerve problems in people with diabetes.

Hypertension

Treating Hypertension with Excercise
People with hypertension are three times more likely to have a heart attack, five times more likely to develop heart failure, and eight times more likely to suffer a stroke than people with normal blood pressure.

The problem with high blood pressure is that nearly one third of the folks who have it do not know it because they never experience any symptoms. However, overtime the force of that pressure damages the blood vessels.
However, hypertension is not predestined. Reducing salt intake, adopting a desirable dietary pattern losing weight and exercising can all help prevent hypertension.
Quitting bad habits and eating a low fat diet will help, but the most significant thing that you can do is to exercise.
For this reason and after a series of careful considerations, some researchers have observed that exercise can prevent and effectively control this deadly disease. One study further showed that moderate exercise several times a week is more effective than extremely vigorous exercise done twice as often.
Such information has led some people to think of exercise as a cure for heart disorders, a fail-safe protection against hypertension or death. That is not so. Even marathon runners that have suffered hypertension, and exercise cannot overcome combination of other risk factor.
What Causes Hypertension?
Sometimes abnormalities of the kidney are responsible. There is also a study wherein the researchers identified more common contributing factors such as heredity, obesity, and lack of physical activity. Therefore, what can be done to lower blood pressure and avoid the risk of developing hypertension? Again, exercise seems to be just what the doctor ordered.
If you think that is what he will do, then, try to contemplate on this list and find some ways how you can incorporate these things into your lifestyle and start to live a life free from the possibilities of developing hypertension. However, before you start following the systematic instructions, it would be better to review them first before getting into action.
- Check with your doctor before beginning any workout program, or if you make any significant changes in your level of physical activity.
- Start at a low, comfortable level of exertion and progress gradually.
- Determine your safety limit for exertion. Use some clues such as sleep problems or fatigue the day after a workout to check on whether you are overdoing it. Once identified, stay within it. Over-exercising is both dangerous and unnecessary.
- engage in regular aerobic exercise for 30 or 40 minutes three or four times a week. Such exercise has been shown to lower blood pressure and prevent heart attacks.
- The safest and best exercise is walking; swimming is a close second. People with higher levels of fitness may choose activities that are more strenuous.
There are certain herbs you can take to help with the lowering of your blood pressure also. Herbs like garlic, hawthorn, reishi, coleus, and dandelion are very useful in controlling your hypertension.
