Arthritis is a condition that causes pain, stiffness and swelling in the joints. Osteoarthritis is a common form of arthritis caused by the wearing down of the cartilage that protects the bones of a joint. Rheumatoid arthritis is an autoimmune condition caused by an inflammation in the lining of the joints. Both forms of arthritis cause pain, tenderness, and swelling, and may result in loss of movement in the affected joints. Over time, joints affected by arthritis may become severely damaged. Arthritis occurs more frequently in older individuals, however it sometimes develops in athletes from overuse of a joint or after an injury. It can however, affect people of any age, including children.

A heart attack occurs when the coronary arteries, the blood vessels that deliver blood to the heart, are suddenly blocked and cannot supply the heart with blood and oxygen. This blockage causes damage and gradual death of the heart muscle and often requires immediate treatment in order to save the person's life. Also known as a myocardial infarction, heart attacks most often occur as a result of coronary artery disease, a condition in which plaque builds up inside the arteries. Heart attacks are the leading cause of death for men and women in the United States.

Low blood pressure, also known as hypotension, is a goal that many people try to achieve in order to avoid the symptoms and complications of high blood pressure. Yet when blood pressure is too low, it can be a serious medical condition, potentially causing permanent damage to the heart and the brain.

High blood pressure, also known as hypertension, occurs when the pressure of the blood flowing against the artery walls is above the normal range. Blood pressure is determined by the amount of blood the heart pumps and the blood flow resistance in the arteries. If the heart pumps more blood than normal, and the arteries are narrower than normal, the result is high blood pressure. Untreated high blood pressure can cause serious health problems, including heart attack, kidney failure and stroke. There are two types of high blood pressure: primary and secondary. Primary hypertension is high blood pressure that develops gradually over the course of time, and secondary hypertension is high blood pressure that results from an underlying...

High blood pressure, also known as hypertension, occurs when the pressure of the blood flowing against the artery walls is above the normal range. Blood pressure is measured in two sets of numbers. The first number is the systolic reading, which is the pressure when the heart is beating. The second number is the diastolic number, the pressure when the heart is resting. High blood pressure occurs when the systolic reading is at 140 or higher and/or the diastolic reading is 90 or above.

Osteoporosis is a condition that causes the bones to become weak and brittle and at a high risk for fracture. In all individuals, bone breaks down over time, but is replaced with new bone tissue. As people age, bone loss occurs at a faster rate than new bone mass is created, resulting in osteoporosis. Osteoporosis is the result of increasing bone loss and is more common in older people, especially women.

A stroke occurs when there is a reduction in the flow of blood to the brain. The lack of blood supply may be the result of a blockage in an artery or a burst blood vessel in the brain. A stroke deprives brain tissue of oxygen and nutrients, causing brain cells to die. A stroke is a medical emergency and requires immediate attention by a medical professional. Prompt treatment can minimize damage to the brain and prevent further complications.

Bed sores (pressure sores) develop when blood to a particular area is cut off as a result of extended periods of time spent either sitting or lying down in one position. Bed sores injure the skin and the tissue beneath it, and worsen rapidly once they develop. Bony areas such as the heels, ankles, hips and tailbone are typically affected. People who are paralyzed or bedridden, use wheelchairs, or cannot adjust their positions on their own are susceptible to developing bed sores.

Blood thinners are medications used to prevent blood clots from forming in the circulatory system. If a blood clot forms in a vein or artery, it can travel to the heart, brain or lungs, causing, depending on the clot's location, a heart attack, stroke or pulmonary embolism. People who have irregular heart rhythms (atrial fibrillation) or congenital heart defects, or who have had coronary stents inserted or undergone heart-valve surgery, have a greater likelihood of getting blood clots.

Healthy bones are a necessity for a full and active lifestyle. Although we depend on our bones everyday for physical support and consider them strong and rigid structures, bones are actually living tissue, growing and changing on a regular basis. Along with the calcium that gives them their strength, bones are also made up of a collagen protein that gives them flexibility but also makes them susceptible to weakening and injury.

Each year, cataracts affect millions of people, including more than half of all Americans aged 60 and older. A cataract is a painless clouding of the eye's natural lens that is caused by a buildup of protein. A cataract can form in one or both eyes. If left untreated, cataracts worsen over time and interfere with everyday activities such as reading or driving. Night vision is usually most affected. When cataracts are in their early stages, people are helped by brighter lighting. As cataracts get worse, however, most people require surgery.
