Leg Pain Can Mean Heart Danger

Leg Pain.

David Dow thought he was having back problems, and that his legs were hurting as a result. As it turns out, that pain may have saved his life.

An otherwise healthy 57-year-old, he figured he just needed to learn some back-strengthening exercises, so he found a personal trainer to help him. But despite the workouts, his leg pain got worse making it hard for him even to walk from the car to the grocery store entrance. He and the trainer suspected something else was wrong and he sought the advice of his doctor. Soon his doctor's tests revealed the true cause: blockages in the blood vessels of his legs. In fact, the arteries going to his lower extremities were nearly 100 percent blocked. The cause? Years of heavy smoking and high-fat meals, and other factors had caused cholesterol, scar tissue and blood clots to build up inside his blood vessels.

How Many Calories Should I Eat?

Calories.

The number of calories people should eat each day depends on several factors, including their age, size, height, sex, lifestyle, and overall general health. A physically active 6ft 2in male, aged 22 years, requires considerably more calories than a 5ft 2ins sedentary woman in her 70s.

Recommended daily calorie intakes also vary across the world. According to the National Health Service (NHS), UK, the average male adult needs approximately 2,500 calories per day to keep his weight constant, while the average adult female needs 2,000.

Tumors Continue Growing Even When Cells Get Old

Tumors.

Based on the knowledge that cancer cells grow indefinitely, the general belief is that senescence could act as a barrier against tumor growth and has the potential of being used as a cancer treatment.

According to findings published in the 19th January issue of the open-access journal PLoS Computational Biology, a collaboration between a cancer biologist from the University of Milano, Italy, and two physicists, from the National Research Council of Italy and from Cornell University, has shown that although cell senescence occurs spontaneously in melanoma cells, it does not stop their growth, which is sustained by a small population of cancer stem cells.

All about Diabetes

Diabetes.

Loss of sensation in the lower limbs and feet contributes to the risk of developing foot ulcers. It is thus important that persons with diabetes wear properly fitting shoes and regularly examine their own feet for sores or other skin changes.

What is Diabetic Neuropathy? Neuropathy, in common English, means nerve disease. Diabetic neuropathy affects peripheral nerves - those outside of the brain and the spinal cord, such as nerves in the arms, legs, hands and feet. Some elderly diabetics with neuropathy also develop a condition called diabetic myopathy (muscle wasting), in which the small muscles of the foot, as well as some other muscles, become thinner and weaker.

What You Need To Know about Plastic Bottle Safety

Plastic Bottle.

Plastic bottles have been linked to cancer and other health problems. But are all plastic containers the same and are they all potential health hazards?

Glass is rarely used for most personal care, skin care or cosmetic products. On the other hand, plastic is everywhere in products we use daily, including food, cleaning products, even care of newborn babies.

In today’s market a symbol and number on the bottom identify most plastic containers. This information is important and tells you what type of plastic is used, if it’s recyclable, and if it is safe or not. Certain ingredients can affect the plastic they are contained in and some plastics can leach chemicals into the products they contain.

Supplement Your Prescription: What Your Doctor Doesn’t Know About Nutrition

Supplement.

“For every dollar we spend on prescription drugs, we spend a dollar to fix a complication. Understanding how nutritional supplements affect these drugs could make them safer andmore effective.” —Mehmet Oz, M.D.

A little known but potentially life-saving fact is that common medications deplete vital nutrients essential to your health. Here’s a practical guide to avoid drug-induced nutrient depletion, and even, replace your medications with natural supplements. We have been called a pill-popping society, and statistics bear this out. Nearly 50 percent of American adults take at least one prescription drug, and 20 percent take three or more.

Have a Drink! The Importance of Water

Have a Drink!

Name a drink that can increase your alertness, prevent you from fainting after giving blood, and even promote a teensy bit of weight loss.

Think it’s one of those “miraculous” multi-level marketing elixirs made of exotic juices that sell for about 40 bucks a pop? Well, think again...continue reading. The drink I’m talking about doesn’t cost anything, yet most of us don’t get enough of it. I’m talking about…water.

The Extraordinary Benefits of Omega-3s

Omega 3.

Research on the incredible health benefits of the omega-3s is published almost on a daily basis. The marine omega-3 fatty acids, DHA and EPA play a crucial role in the development of the brain, nervous system and the eye.

Even the medical community has been caught up in the excitement. In 2002, the American Heart Association issued a scientific statement on the effects of omega-3 fatty acids on heart health. The statement endorsed raising our levels of DHA and EPA either by eating fish or by taking a daily fish oil supplement.

BlackBerry Z10 Complete Review and Specification

BlackBerry Z10.

The BlackBerry Z10 is the first handset to use the new Blackberry 10 Operating System (OS) and is a fully touch-screen device. It can be viewed as the start of something new for BlackBerry. Something that they’re hoping can bring them back among the top of the smartphone market.

Aside from having a full touch-screen, the Z10 now also runs on a regular data plan, removing the Blackberry Internet Service (BIS). Those who have always gotten confused with BIS versus the data plan won’t have to worry about understanding that thing anymore (I remember having to explain the difference of the data plan and the BIS to a lot of people in the past).

So let’s check out what this smartphone has to offer and if it can propel BlackBerry to the top.

What Causes Leg Pain?

Leg Pain.

Leg pain refers to any kind of pain that occurs between the heels and the pelvis. There are many reasons for leg pain, and not all of them are caused by a problem that originates in the leg; some injuries or spinal problems can cause aches and pains in the leg(s). 

Leg pain can be long-term, transitory, intermittent, acute, or slowly progressive. Pain may affect just part of the leg, such as the knee, or the whole limb. Leg pain may be felt as tingling, sharp, dull, an ache, or a stabbing sensation. Some leg pains may be just a nuisance, in some cases the cause may never be found, other leg pains may be a sign of a more serious disease or condition, even a life-threatening one. Leg pain caused by trauma Trauma has a medical and psychiatric meaning. In this text, it refers to the medical meaning.

A Broken Heart Breaks Your Heart, Literally!

Broken Heart.

According to an article published in Circulation: Journal of the American Heart Association, heart attack risk after bereavement is much higher for several weeks after the loss. The day the loved one dies, the risk of a heart attack is a stunning twenty one times higher. 
The article also warns friends and family to look for signs of heart failure in the bereaved person, ensuring they relax and maintain any medication regime they may be on. The study was conducted with nearly 2000 adult heart attack survivors and while the risk of a heart problem declined over the first month, it still remained at six times the normal risk during the first week after a loved one died.

What Is Normal Blood Pressure?

Blood Pressure.

Blood pressure is primarily produced when the heart muscle contracts - it is the pressure of blood upon the walls of the blood vessels. There are two recordings, a high one (systolic) and a lower one (diastolic). The systolic pressure is measured when the heart contracts, while the diastolic one is gauged just before the heart contracts. 
The heart is the muscle that pumps blood throughout the body during every second of our lives. Low-oxygen blood is pumped towards the lungs, where it becomes oxygen-rich again. Oxygen-rich blood is pumped by the heart around to body to supply tissue, muscle, organs and cells. This pumping generates blood pressure.
According to Medilexicon's medical dictionary, Blood Pressure is: "The pressure or tension of the blood within the systemic arteries, maintained by the contraction of the left ventricle, the resistance of the arterioles and capillaries, the elasticity of the arterial walls, as well as the viscosity and volume of the blood; expressed as relative to the ambient atmospheric pressure."

All about Blood Pressure, Hypotension and Hypertension

Hypertension.

Low blood pressure is also known as hypotension. For millions of people who suffer from hypertension (high blood pressure) hypotension may seem great. If symptoms are mild hypotension usually requires no treatment. However, it can cause serious heart disorders, fainting and also lead to neurological and endocrine disorders. If hypotension is severe key organs can become deprived of oxygen and nutrients and the body can go into shock, a life-threatening condition. 

According to Medilexicon's medical dictionary, hypotension is "1. Subnormal arterial blood pressure. 2. Reduced pressure or tension of any kind." What is blood pressure? The heart is a muscle that pumps blood around the body continuously. Blood that is low in oxygen is pumped towards the lungs, where oxygen supplies are replenished. The heart pumps this oxygen-rich blood around the body to supply our muscles and cells. The pumping of blood generates pressure - blood pressure.

All about a Stroke

Types of Stroke.

A stroke is a condition in which the brain cells suddenly die because of a lack of oxygen. This can be caused by an obstruction in the blood flow, or the rupture of an artery that feeds the brain. The patient may suddenly lose the ability to speak, there may be memory problems, or one side of the body can become paralyzed. 
The two main types of stroke include ischemic stroke and hemorrhagic stroke. Ischemic stroke accounts for about three-quarters of all strokes and occurs when a blood clot, or thrombus, forms that blocks blood flow to part of the brain. If a blood clot forms somewhere in the body and breaks off to become free-floating, it is called an embolus. This wandering clot may be carried through the bloodstream to the brain where it can cause ischemic stroke.A hemorrhagic stroke occurs when a blood vessel on the brain's surface ruptures and fills the space between the brain and skull with blood (subarachnoid hemorrhage) or when a defective artery in the brain bursts and fills the surrounding tissue with blood (cerebral hemorrhage). Both types of stroke result in a lack of blood flow to the brain and a buildup of blood that puts too much pressure on the brain.
The outcome after a stroke depends on where the stroke occurs and how much of the brain is affected. Smaller strokes may result in minor problems, such as weakness in an arm or leg. Larger strokes may lead to paralysis or death. Many stroke patients are left with weakness on one side of the body, difficulty speaking, incontinence, and bladder problems.

10 Risk Factors for Cancer

A Cancer.

What is cancer? Cancer is a term used for diseases in which abnormal cells divide without control and are able to invade other tissues. Cancer cells can spread to other parts of the body through the blood and lymph systems. Cancer is not just one disease but many diseases. 
There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer that begins in basal cells of the skin is called basal cell carcinoma. Cancer types can be grouped into broader categories:
