Bodybuilding and Cardiovascular Health

Cardiovascular health is very important for bodybuilders and anabolic steroid-using athletes. As we know certain anabolic-androgenic steroids are associated with unfavorable changes in cholesterol, heart attacks and heart failure are some of the most frequent causes of sudden death or serious injuries. Elite bodybuilders and many other anabolic steroids users have suffered heart problems.

The term”Cardiovascular” refers to the heart and the blood vessels. Heart damage is generally caused by ischemia (oxygen deprivation) but can also be electrical in nature, as the heartbeat is generated by an internal conduction system that accelerates and decelerates to meet the circulatory command of the body. When the electrical signal is disrupted, the heart does not beat well or if the disruption is severe enough, may not beat at all. Ischemic damage of the heart s often due to a increase of plaque in the arteries, but may also be due to inappropriate vasoconstriction. Many abusers of cocaine suffered heart attacks due to coronary vasoconstriction, even though their arteries were completely healthy.

When ischemia is mild-to-moderate and long-term, the body grows new blood vessels to cut down the distance between active cells and near capillaries. A person who lives in the mountains likely has a higher capillary density than a person who lives on the beach at sea level. This density is a measure a measure of how branched the circulation is to provide oxygen. Many endurance athletes sleep in individual chambers that copy living in the mountains. This increases their red blood cell supply by stimulating the hormone erythropoietin, and probably excites new blood vessel growth. Many cancer drugs kill tumors by slowing down the blood vessel growth, starving the malignant tumors of oxygen and nutrients.

Common Signs of Heat Stroke

According to MedicineNet in "Definition of Heat Stroke," heat stroke occurs when the body's core temperature rises above 104°F (40°C) and is accompanied by hot, dry skin and central nervous system abnormalities such as delirium, convulsions or coma. Since heat stroke is a life-threatening condition, it is important to watch people for heat stroke symptoms. MedicineNet states that heat stroke that results from exposure to high environmental temperatures is termed nonexertional heat stroke, and heat stroke that results from strenuous exercise is called exertional heat stroke. Regardless of the type of heat stroke a person experiences, heat stroke signs are life-threatening, and immediate medical attention is necessary when heat stroke symptoms begin. When the body cannot control its temperature, heat stroke occurs because the sweating mechanism fails. The body is not able to cool down. Body temperature can rise to 106°F (41.1°C) or higher within a few minutes. Hea

Causes of Easy Bruising: Reasons Why People Bruise Easily

Bruising , a reddish or purple discoloration under the skin, most often results from trauma to the small blood vessels, called capillaries, but can also occur spontaneously. How and Why Bruises Occur Blood leaks out of the capillaries and accumulates under the skin, gradually absorbing over several days. Bruising most often occurs because people run into objects or experience other trauma. Most bruising is easily explained, but frequent bruising that occurs without obvious cause needs prompt investigation, since several serious diseases can cause bruising. In general, women bruise more easily than men. How Aging Increases the Risk of Easy Bruising Bruising increases as people age for several reasons. Skin thins as people age and the capillaries become more fragile. The layer of fat that cushions blood vessels and protects them from injury becomes thinner as well. Older people often take medications and supplements that thin the blood and contribute to easy bruising. Visi

Stye - Symptoms and Treatment

A stye is an infection, typically a bacterial infection, which causes a painful red lump either on the edge or inside of the eyelid. Bacteria grow at the root of an eyelash follicle or inside an oil gland. The bacteria can be a result of poor hygiene, touching the eyes with unwashed hands or chronic inflammation. The stye resembles a pimple or a boil and is usually filled with pus. A stye does not pose a risk to vision and most often heals without treatment within a week. However, a stye may require treatment with a doctor if the infection does not resolve with at-home remedies. Symptoms of a Stye A stye is not usually hard to spot. Not only does a red lump form on either the top or bottom eyelid, but pain is also an immediate symptom of the condition. Typical symptoms of a stye include: red lump on the eyelid similar to a pimple watering of the eye eyelid pain and swelling clear or yellow fluid collecting in the stye A normal stye will come to a head in approximately three to
