What Is A Blood Clot
Blood clots are gel-like collections of blood that form in your veins or arteries when blood changes from liquid to partially solid. Clotting is a normal function that stops your body from bleeding too much when you get hurt. However, blood clots that form in some places and dont dissolve on their own can be dangerous to your health.
Normally, a blood clots start as a response to injury of a blood vessel. At first, the blood stays in one place. Two substances platelets and fibrin combine to form what is called a platelet plug to stop up the cut or hole.
When a blood clot forms where it should not have developed, it is called a thrombus. A blood clot is also called a thrombus. The clot may stay in one spot or move through the body . The clots that move are especially dangerous. Blood clots can form in arteries or veins .
The symptoms of a blood clot, and the recommended treatment, depend on where a clot forms in your body and how much damage it could cause. Knowing the most common blood clot signs and risk factors can help you spot or even prevent this potentially life-threatening condition.
Risk Factors For Blood Clots
People with a hereditary predisposition to or a history of clotting may be at higher risk for brain blood clots. In Clintons case, she was diagnosed with a deep venous thrombosis a clot found most often in the leg in 1998, so that may have been a sign that she is predisposed to clotting.
Dehydration may also put a person whos already predisposed at a higher risk for clotting, because the blood is thicker and more concentrated. Clintons clot was preceded by a stomach flu that could have caused her to be dehydrated.
Signs That Life May Be Ending
Its not usually possible to predict exactly when someone might die, but there are some signs that show someone is close to the end of their life. In the final days and hours, they may become drowsier, or stop eating and drinking. They can appear confused or restless.
Their breathing can change, and become less regular. It may be noisy, due to fluids building up in the airways. This doesnt always cause distress to the person, but can be worrying for people around them. Some things can help, such as raising their upper body or suction treatment, and medication can be given if needed.

What Are Blood Clots
Blood clots are differently sized clumps of blood that have formed inside your body. Clotting is important to prevent excessive bleeding if you are injured or cut. However, when a blood clot blocks blood flow to important areas of your body, it can be harmful, even deadly. Blood clots can occur in your arms and legs, abdomen , heart, lungs, brain, and kidneys.
There are two different types of blood clots. These include clots that stay in place and dont move and those that break away from the spot where they developed and move to different areas inside your body . Depending on what the clot blocks or where it moves, a blood clot can be deadly.
Blood Clots In The Brain: Causes
There are many reasons a person may have a clot in the brain. Here we take a detailed look at the causes of blood clots in the brain:
Head injuries. If there is a serious injury or trauma to the head and/or neck, the body will form a clot to stop the bleeding. This can put a lot of pressure on surrounding brain tissue. Some traumas can cause blood clots to form outside the brain and break loose. These have the potential to become lodged in the brain and cause a stroke.
Narrowing or hardening arteries. When arteries harden or narrow the risk of developing a clot in the brain increases. Hardened arteries can tear as they pump blood, which can lead to a clot forming. These clots can cut blood flow off to the narrowed artery, causing serious damage to surrounding cells.
Travelling clots. Some clots will travel from one part of the body to a blood vessel that leads to the brain, causing a blockage, which can result in a stroke or cerebral embolism. These clots can cause damage to other parts of the body before they reach the brain.
Inflammation. If a superficial vein is overinflamed it can lead to an increased risk of blood clots. An injury or bacterial infection can cause inflammation. This can reduce blood flow and damaged areas will be at risk of leaking, which can lead to blood clots.

Causes Of Blood Clot In The Brain
Head injuries or trauma to the brain, head and neck can cause these clots to form in the brain. Blood clots in the brain are caused when bleeding occurs between the skull and the brain. The body will form a clot to stop the bleeding, which will put pressure on the surrounding brain tissue. Trauma to the head can also cause blood clots formed outside of the brain to break loose and become lodged in the brain, which can cause an ischemic stroke.
Travelling clots from other parts of the body will travel to a blood vessel that leads to the brain, causing a blockage and then an embolic stroke or cerebral embolism. These travelling clots are more likely to cause damage to other parts of the body before they reach the brain.
Narrowing or hardening of the arteries, commonly known as atherosclerosis, can increase someone’s vulnerability to developing a clot in the brain. Hardened arteries are at risk of tearing as they pump blood, which can cause a clot to form in the damaged area so blood does not leak into the body. These clots can cut off blood flow to the narrowed artery, causing damage to the surrounding cells.
Women who use oral contraceptives may be at an increased risk for blood clotting. Women who have a history of blood clots, are over the age of 35 or smoke and continue to use contraceptives have an extremely high risk of developing blood clots which should be addressed by your doctor.
Blood Clots Are No Joke
As you can see from above, blood clots are no joke and should be taken seriously. If you are suffering from any of the symptoms for an extended period of time, make sure to see a doctor and get yourself checked out. The sooner you get it diagnosed, the quicker they can get it worked on. In the meantime, the tips for naturally preventing a blood clot are there. They will not only help with blood clots, but they are pretty good health tips in general.

Prevention Of Blood Clot In The Brain
Knowing the risk factors for a blood clot is the first step towards being informed. In most cases, all one needs to do to prevent the formation of a blood clot is to follow a doctors recommendations and stringently following a healthy lifestyle.
It also improves overall cardiovascular health. Exercise also helps lower cholesterol, manage conditions like diabetes, maintain weight, and reduce stress. 30 minutes of moderate physical activity for at least 5 days of the week is the usual recommendation, though this can vary from case to case depending on the medical history.
It also helps you lose weight, control diabetes and reduce stress. Good examples of aerobic exercise include swimming, cycling, jogging or walking.
Deep Vein Thrombosisthe Blood Clot That Can Kill
According to the National Blood Clot Alliance, 274 people will die every day from the consequences of a blood clot. Neither age nor gender offer protection: you can develop a clot just as easily at 25 years of age as 85 years of age. Most are the result of a traumatic injury, a surgical complication or due to taking hormone replacement therapy. Some birth control medications also present an increased risk of blood clots in susceptible patients.
A thrombosis is a blood clot that blocks the normal flow of blood through an artery or vein. A deep vein thrombosis occurs in the deeper veins-for example in the lower leg or calf. However, thromboses can occur anywhere in the body including the upper limbs . The latter are much less frequent: 10% of all DVTs are found in the upper limb and usually result from the use of catheters surgery or trauma to the neck or shoulder.
The risks from DVTs vary and can include tissue necrosis , swelling and pain. The most important risk occurs when part of the clot breaks off and travels to the lung or brain. The resulting damage is always significant and may lead to sudden death.
Symptoms of a DVT in the leg include swelling and cramping pain or soreness in the calf muscles. The skin over the area can become reddened or warm to the touch because of the underlying inflammation.
The warning signs and symptoms of a pulmonary embolism include:

What Are The Causes Of Brain Bleeds
Bleeding in the brain has a number of causes, including:
- Head trauma, caused by a fall, car accident, sports accident or other type of blow to the head.
- High blood pressure , which can damage the blood vessel walls and cause the blood vessel to leak or burst.
- Buildup of fatty deposits in the arteries .
- Blood clot that formed in the brain or traveled to the brain from another part of the body, which damaged the artery and caused it to leak.
- Ruptured cerebral aneurysm .
- Buildup of amyloid protein within the artery walls of the brain .
- A leak from abnormally formed connections between arteries and veins .
- Bleeding disorders or treatment with anticoagulant therapy .
- Brain tumor that presses on brain tissue causing bleeding.
- Smoking, heavy alcohol use, or use of illegal drugs such as cocaine.
- Conditions related to pregnancy or childbirth, including eclampsia, postpartum vasculopathy, or neonatal intraventricular hemorrhage.
- Conditions related to abnormal collagen formation in the blood vessel walls that can cause to walls to be weak, resulting in a rupture of the vessel wall.
What Happens During A Stroke
If something happens to block the flow of blood, brain cells start to die within minutes because they cant get oxygen. This causes a stroke.
There are two types of stroke:
- An ischemic stroke occurs when blood clots or other particles block the blood vessels to the brain. Fatty deposits called plaque can also cause blockages by building up in the blood vessels.
- A hemorrhagic stroke occurs when a blood vessel bursts in the brain. Blood builds up and damages surrounding brain tissue.
Both types of stroke damage brain cells. Symptoms of that damage start to show in the parts of the body controlled by those brain cells.

Having Blood Clots In Your Brain Can Be Serious Which Needs To Be Spotted Diagnosed And Treated Timely Lucky You
A blood clot in the brain can cause an ischemic stroke which is caused by an artery to the brain becoming blocked and starving a portion of the brain of oxygen and nutrients. A clot in the brain can also cause a buildup of cellular waste and carbon dioxide because the brain will be unable to clear this waste properly. This can cause the cells around the blockage to die, and the neurons in this portion of the brain to stop working, which can cause damage throughout the body. If you suspect that you have blood clots in the brain, immediate treatment will be necessary to avoid a life-threatening condition.

Treatment Options For Blood Clots
There are several types of brain blood clot treatments available, depending on the location and severity of the clot. Anticoagulant drugs , which were prescribed to Clinton, are very good at breaking down clots and preventing new ones from forming. An MRI scan is often used to make sure the clot remains the same size or is getting smaller. In more severe cases, as in a complete block of an artery, surgery may be required, in which a catheter is inserted to break down and remove the clot.

Can Blood Clots Be Prevented Or Avoided
Blood clots are highly preventable. To prevent or avoid a blood clot, know your personal risk factors and control the risks you can. For example, if you smoke, stop. If you are obese, lose weight. If you take birth control pills, talk to your doctor about an effective alternative. If you are inactive, get moving. If you have a family history of blood clots, talk to your doctor. Your doctor may determine whether you should be taking blood-thinning medicine to prevent clots.
There are several situations in life that increase your risk for blood clots. These include:
- When you are pregnant
- When you have just had major surgery
- When you have cancer

How Is Cerebral Venous Sinus Thrombosis Diagnosed
People who have had any type of stroke recover best if they get treatment immediately. If you suspect a stroke based on the symptoms, have someone take you immediately to the emergency room, or call 911 to get help.
Doctors typically take a medical history and do a physical exam. Family and friends can describe the symptoms they saw, especially if the person who had the stroke is unconscious. The final diagnosis, however, is usually made based on how the blood is flowing in the brain. Imaging tests show areas of blood flow. These tests may be used to diagnose venous sinus thrombosis:
- MRI scan
What Recovery Can I Expect After A Brain Hemorrhage
Besides depriving the brain of oxygen and killing brain cells, bleeding inside the brain also prevents nerve cells from communicating with the parts of the body and the functions they control. This results in a loss of memory, speech or movement in the affected area.
Depending on the location of the hemorrhage, the extent of damage and your age and overall health, there can be lasting effects from a brain bleed. These affects can include:
- Inability to move part of the body .
- Numbness or weakness in part of the body.
- Difficulty swallowing.
- Difficulty speaking or understanding spoken or written words.
- Confusion, memory loss or poor judgment.
- Personality change and/or emotional problems.
However, over time and with a lot of effort and determination in rehabilitation , you can regain some of these lost functions. This is especially true if your general health is otherwise good.
Unfortunately, some patients who remain in a coma, or have been severely paralyzed after an intracranial or cerebral hemorrhage may need permanent, long-term care typically provided in a nursing home. Depending on the type, location and extent of the brain bleed, many patients do not survive the initial bleeding event.

Blood Clots In Brain Causes
Blood clots are the bodys natural defense to damage when a blood vessel is damaged. They basically form to stop the body from bleeding out. Unfortunately, they can also form when the body thinks that a blood cell has been damaged, or if the blood cell has been damaged internallyand thats where the problems can arise.
One of the first things to know when dealing with blood clots, is the various blood clot in brain causes. There are a number of causes of blood clots in the brainsome of which can be prevented, and other causes you can have very little control over.
