What are the treatments for Pernicious Anemia ?
Doctors treat pernicious anemia by replacing the missing vitamin B12 in the body. People who have pernicious anemia may need lifelong treatment.
                
The goals of treating pernicious anemia include:
                
Preventing or treating the anemia and its signs and symptoms
                
Preventing or managing complications, such as heart and nerve damage
                
Treating the cause of the pernicious anemia (if a cause can be found)
                
Specific Types of Treatment
                
Pernicious anemia usually is easy to treat with vitamin B12 shots or pills.
                
If you have severe pernicious anemia, your doctor may recommend shots first. Shots usually are given in a muscle every day or every week until the level of vitamin B12 in your blood increases. After your vitamin B12 blood level returns to normal, you may get a shot only once a month.
                
For less severe pernicious anemia, your doctor may recommend large doses of vitamin B12 pills. A vitamin B12 nose gel and spray also are available. These products may be useful for people who have trouble swallowing pills, such as older people who have had strokes.
                
Your signs and symptoms may begin to improve within a few days after you start treatment. Your doctor may advise you to limit your physical activity until your condition improves.
                
If your pernicious anemia is caused by something other than a lack of intrinsic factor, you may get treatment for the cause (if a cause can be found). For example, your doctor may prescribe medicines to treat a condition that prevents your body from absorbing vitamin B12.
                
If medicines are the cause of your pernicious anemia, your doctor may change the type or dose of medicine you take. Infants of strict vegetarian mothers may be given vitamin B12 supplements from birth. + NHLBI + Pernicious Anemia
How to prevent Pernicious Anemia ?
You can't prevent pernicious anemia caused by a lack of intrinsic factor. Without intrinsic factor, you won't be able to absorb vitamin B12 and will develop pernicious anemia.
                
Although uncommon, some people develop pernicious anemia because they don't get enough vitamin B12 in their diets. You can take steps to prevent pernicious anemia caused by dietary factors.
                
Eating foods high in vitamin B12 can help prevent low vitamin B12 levels. Good food sources of vitamin B12 include:
                
Breakfast cereals with added vitamin B12
                
Meats such as beef, liver, poultry, and fish
                
Eggs and dairy products (such as milk, yogurt, and cheese)
                
Foods fortified with vitamin B12, such as soy-based beverages and vegetarian burgers
                
If youre a strict vegetarian, talk with your doctor about having your vitamin B12 level checked regularly.
                
Vitamin B12 also is found in multivitamins and B-complex vitamin supplements. Doctors may recommend supplements for people at risk for vitamin B12 deficiency, such as strict vegetarians or people who have had stomach surgery.
                
Older adults may have trouble absorbing vitamin B12. Thus, doctors may recommend that older adults eat foods fortified with vitamin B12 or take vitamin B12 supplements. + NHLBI + Pernicious Anemia
What is (are) Deep Vein Thrombosis ?
Espaol
                
Deep vein thrombosis (throm-BO-sis), or DVT, is a blood clot that forms in a vein deep in the body. Blood clots occur when blood thickens and clumps together.
                
Most deep vein blood clots occur in the lower leg or thigh. They also can occur in other parts of the body.
                
A blood clot in a deep vein can break off and travel through the bloodstream. The loose clot is called an embolus (EM-bo-lus). It can travel to an artery in the lungs and block blood flow. This condition is called pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE.
                
PE is a very serious condition. It can damage the lungs and other organs in the body and cause death.
                
Blood clots in the thighs are more likely to break off and cause PE than blood clots in the lower legs or other parts of the body. Blood clots also can form in veins closer to the skin's surface. However, these clots won't break off and cause PE.

The animation shows how a blood clot in a deep vein of the leg can break off, travel to the lungs, and block blood flow. + NHLBI + Deep Vein Thrombosis
What causes Deep Vein Thrombosis ?
Blood clots can form in your body's deep veins if:
                
A vein's inner lining is damaged. Injuries caused by physical, chemical, or biological factors can damage the veins. Such factors include surgery, serious injuries, inflammation, and immune responses.
                
Blood flow is sluggish or slow. Lack of motion can cause sluggish or slow blood flow. This may occur after surgery, if you're ill and in bed for a long time, or if you're traveling for a long time.
                
Your blood is thicker or more likely to clot than normal. Some inherited conditions (such as factor V Leiden) increase the risk of blood clotting. Hormone therapy or birth control pills also can increase the risk of clotting. + NHLBI + Deep Vein Thrombosis
Who is at risk for Deep Vein Thrombosis? ?
The risk factors for deep vein thrombosis (DVT) include:
                
A history of DVT.
                
Conditions or factors that make your blood thicker or more likely to clot than normal. Some inherited blood disorders (such as factor V Leiden) will do this. Hormone therapy or birth control pills also increase the risk of clotting.
                
Injury to a deep vein from surgery, a broken bone, or other trauma.
                
Slow blood flow in a deep vein due to lack of movement. This may occur after surgery, if you're ill and in bed for a long time, or if you're traveling for a long time.
                
Pregnancy and the first 6 weeks after giving birth.
                
Recent or ongoing treatment for cancer.
                
A central venous catheter. This is a tube placed in a vein to allow easy access to the bloodstream for medical treatment.
                
Older age. Being older than 60 is a risk factor for DVT, although DVT can occur at any age.
                
Overweight or obesity.
                
Smoking.
                
Your risk for DVT increases if you have more than one of the risk factors listed above. + NHLBI + Deep Vein Thrombosis
What are the symptoms of Deep Vein Thrombosis ?
The signs and symptoms of deep vein thrombosis (DVT) might be related to DVT itself or pulmonary embolism (PE). See your doctor right away if you have signs or symptoms of either condition. Both DVT and PE can cause serious, possibly life-threatening problems if not treated.
                
Deep Vein Thrombosis
                
Only about half of the people who have DVT have signs and symptoms. These signs and symptoms occur in the leg affected by the deep vein clot. They include:
                
Swelling of the leg or along a vein in the leg
                
Pain or tenderness in the leg, which you may feel only when standing or walking
                
Increased warmth in the area of the leg that's swollen or painful
                
Red or discolored skin on the leg
                
Pulmonary Embolism
                
Some people aren't aware of a deep vein clot until they have signs and symptoms of PE. Signs and symptoms of PE include:
                
Unexplained shortness of breath
                
Pain with deep breathing
                
Coughing up blood
                
Rapid breathing and a fast heart rate also may be signs of PE. + NHLBI + Deep Vein Thrombosis
How to diagnose Deep Vein Thrombosis ?
Your doctor will diagnose deep vein thrombosis (DVT) based on your medical history, a physical exam, and test results. He or she will identify your risk factors and rule out other causes of your symptoms.
                
For some people, DVT might not be diagnosed until after they receive emergency treatment for pulmonary embolism (PE).
                
Medical History
                
To learn about your medical history, your doctor may ask about:
                
Your overall health
                
Any prescription medicines you're taking
                
Any recent surgeries or injuries you've had
                
Whether you've been treated for cancer
                
Physical Exam
                
Your doctor will check your legs for signs of DVT, such as swelling or redness. He or she also will check your blood pressure and your heart and lungs.
                
Diagnostic Tests
                
Your doctor may recommend tests to find out whether you have DVT.
                
Common Tests
                
The most common test for diagnosing deep vein blood clots is ultrasound. This test uses sound waves to create pictures of blood flowing through the arteries and veins in the affected leg.
                
Your doctor also may recommend a D-dimer test or venography (ve-NOG-rah-fee).
                
A D-dimer test measures a substance in the blood that's released when a blood clot dissolves. If the test shows high levels of the substance, you may have a deep vein blood clot. If your test results are normal and you have few risk factors, DVT isn't likely.
                
Your doctor may suggest venography if an ultrasound doesn't provide a clear diagnosis. For venography, dye is injected into a vein in the affected leg. The dye makes the vein visible on an x-ray image. The x ray will show whether blood flow is slow in the vein, which may suggest a blood clot.
                
Other Tests
                
Other tests used to diagnose DVT include magnetic resonance imaging (MRI) and computed tomography (to-MOG-rah-fee), or CT, scanning. These tests create pictures of your organs and tissues.
                
You may need blood tests to check whether you have an inherited blood clotting disorder that can cause DVT. This may be the case if you have repeated blood clots that are not related to another cause. Blood clots in an unusual location (such as the liver, kidney, or brain) also may suggest an inherited clotting disorder.
                
If your doctor thinks that you have PE, he or she may recommend more tests, such as a lung ventilation perfusion scan (VQ scan). A lung VQ scan shows how well oxygen and blood are flowing to all areas of the lungs.

How to prevent Deep Vein Thrombosis ?
You can take steps to prevent deep vein thrombosis (DVT) and pulmonary embolism (PE). If you're at risk for these conditions:
                
See your doctor for regular checkups.
                
Take all medicines as your doctor prescribes.
                
Get out of bed and move around as soon as possible after surgery or illness (as your doctor recommends). Moving around lowers your chance of developing a blood clot.
                
Exercise your lower leg muscles during long trips. This helps prevent blood clots from forming.
                
If you've had DVT or PE before, you can help prevent future blood clots. Follow the steps above and:
                
Take all medicines that your doctor prescribes to prevent or treat blood clots
                
Follow up with your doctor for tests and treatment
                
Use compression stockings as your doctor directs to prevent leg swelling
                
Contact your doctor at once if you have any signs or symptoms of DVT or PE. For more information, go to "What Are the Signs and Symptoms of Deep Vein Thrombosis?"
                
Travel Tips
                
The risk of developing DVT while traveling is low. The risk increases if the travel time is longer than 4 hours or you have other DVT risk factors.
                
During long trips, it may help to:
                
Walk up and down the aisles of the bus, train, or airplane. If traveling by car, stop about every hour and walk around.
                
Move your legs and flex and stretch your feet to improve blood flow in your calves.
                
Wear loose and comfortable clothing.
                
Drink plenty of fluids and avoid alcohol.
                
If you have risk factors for DVT, your doctor may advise you to wear compression stockings while traveling. Or, he or she may suggest that you take a blood-thinning medicine before traveling. + NHLBI + Deep Vein Thrombosis
Who is at risk for High Blood Pressure? ?
Anyone can develop high blood pressure; however, age, race or ethnicity, being overweight, gender, lifestyle habits, and a family history of high blood pressure can increase your risk for developing high blood pressure.
                
Age
                
Blood pressure tends to rise with age. About 65 percent of Americans age 60 or older have high blood pressure. However, the risk for prehypertension and high blood pressure is increasing for children and teens, possibly due to the rise in the number of overweight children and teens.
                
Race/Ethnicity
                
High blood pressure is more common in African American adults than in Caucasian or Hispanic American adults. Compared with these ethnic groups, African Americans:
                
Tend to get high blood pressure earlier in life.
                
Often, on average, have higher blood pressure numbers.
                
Are less likely to achieve target blood pressure goals with treatment.
                
Overweight
                
You are more likely to develop prehypertension or high blood pressure if youre overweight or obese. The terms overweight and obese refer to body weight thats greater than what is considered healthy for a certain height.
                
Gender
                
Before age 55, men are more likely than women to develop high blood pressure. After age 55, women are more likely than men to develop high blood pressure.
                
Lifestyle Habits
                
Unhealthy lifestyle habits can raise your risk for high blood pressure, and they include:
                
Eating too much sodium or too little potassium
                
Lack of physical activity
                
Drinking too much alcohol
                
Stress
                
Family History
                
A family history of high blood pressure raises the risk of developing prehypertension or high blood pressure. Some people have a high sensitivity to sodium and salt, which may increase their risk for high blood pressure and may run in families. Genetic causes of this condition are why family history is a risk factor for this condition. + NHLBI + High Blood Pressure
What are the symptoms of High Blood Pressure ?
Because diagnosis is based on blood pressure readings, this condition can go undetected for years, as symptoms do not usually appear until the body is damaged from chronic high blood pressure.
                

                
Complications of High Blood Pressure
                
When blood pressure stays high over time, it can damage the body and cause complications. Some common complications and their signs and symptoms include:
                
Aneurysms:When an abnormal bulge forms in the wall of an artery. Aneurysms develop and grow for years without causing signs or symptoms until they rupture, grow large enough to press on nearby body parts, or block blood flow. The signs and symptoms that develop depend on the location of the aneurysm.
                
Chronic Kidney Disease: When blood vessels narrow in the kidneys, possibly causing kidney failure.
                
Cognitive Changes: Research shows that over time, higher blood pressure numbers can lead to cognitive changes. Signs and symptoms include memory loss, difficulty finding words, and losing focus during conversations.
                
Eye Damage: When blood vessels in the eyes burst or bleed. Signs and symptoms include vision changes or blindness.
                
Heart Attack: When the flow of oxygen-rich blood to a section of heart muscle suddenly becomes blocked and the heart doesnt get oxygen. The most common warning symptoms of a heart attack are chest pain or discomfort, upper body discomfort, and shortness of breath.
                
Heart Failure: When the heart cant pump enough blood to meet the bodys needs. Common signs and symptoms of heart failure include shortness of breath or trouble breathing; feeling tired; and swelling in the ankles, feet, legs, abdomen, and veins in the neck.
                
Peripheral Artery Disease: A disease in which plaque builds up in leg arteries and affects blood flow in the legs. When people have symptoms, the most common are pain, cramping, numbness, aching, or heaviness in the legs, feet, and buttocks after walking or climbing stairs.
                
Stroke: When the flow of oxygen-rich blood to a portion of the brain is blocked. The symptoms of a stroke include sudden onset of weakness; paralysis or numbness of the face, arms, or legs; trouble speaking or understanding speech; and trouble seeing. + NHLBI + High Blood Pressure
How to diagnose High Blood Pressure ?
For most patients, health care providers diagnose high blood pressure when blood pressure readings areconsistently 140/90 mmHg or above.
                
Confirming High Blood Pressure
                
A blood pressure test is easy and painless and can be done in a health care providers office or clinic. To prepare for the test:
                
Dont drink coffee or smoke cigarettes for 30 minutes prior to the test.
                
Go to the bathroom before the test.
                
Sit for 5 minutes before the test.
                
To track blood pressure readings over a period of time, the health care provider may ask you to come into the office on different days and at different times to take your blood pressure. The health care provider also may ask you to check readings at home or at other locations that have blood pressure equipment and to keep a written log of all your results.
                
Whenever you have an appointment with the health care provider, be sure to bring your log of blood pressure readings. Every time you visit the health care provider, he or she should tell you what your blood pressure numbers are; if he or she does not, you should ask for your readings.
                
Blood Pressure Severity and Type
                
Your health care provider usually takes 23 readings at several medical appointments to diagnose high blood pressure. Using the results of your blood pressure test, your health care provider will diagnose prehypertension or high blood pressure if:
                
Your systolic or diastolic readings are consistently higher than 120/80 mmHg.
                
Your childs blood pressure numbers are outside average numbers for children of the same age, gender, and height.
                
Once your health care provider determines the severity of your blood pressure, he or she can order additional tests to determine if your blood pressure is due to other conditions or medicines or if you have primary high blood pressure. Health care providers can use this information to develop your treatment plan.
                
Some people have white coat hypertension. This happens when blood pressure readings are only high when taken in a health care providers office compared with readings taken in any other location. Health care providers diagnose this type of high blood pressure by reviewing readings in the office and readings taken anywhere else. Researchers believe stress, which can occur during the medical appointment, causes white coat hypertension. + NHLBI + High Blood Pressure
How to prevent High Blood Pressure ?
Healthy lifestyle habits, proper use of medicines, and regular medical care can prevent high blood pressure or its complications.
                
Preventing High Blood Pressure Onset
                
Healthy lifestyle habits can help prevent high blood pressure from developing. It is important to check your blood pressure regularly. Children should have their blood pressure checked starting at 3 years of age. If prehypertension is detected, it should be taken seriously to avoid progressing to high blood pressure. 
                
Preventing Worsening High Blood Pressure or Complications
                
If you have been diagnosed with high blood pressure, it is important to obtain regular medical care and to follow your prescribed treatment plan, which will include healthy lifestyle habit recommendations and possibly medicines. Not only can healthy lifestyle habits prevent high blood pressure from occurring, but they can reverse prehypertension and help control existing high blood pressure or prevent complications and long-term problems associated with this condition, such as coronary heart disease, stroke, or kidney disease. + NHLBI + High Blood Pressure
What is (are) Anemia ?
Espaol
                
Anemia (uh-NEE-me-uh) is a condition in which your blood has a lower than normal number of red blood cells.
                
Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that gives blood its red color. This protein helps red blood cells carry oxygen from the lungs to the rest of the body.
                
If you have anemia, your body doesn't get enough oxygen-rich blood. As a result, you may feel tired or weak. You also may have other symptoms, such as shortness of breath, dizziness, or headaches.
                
Severe or long-lasting anemia can damage your heart, brain, and other organs in your body. Very severe anemia may even cause death.
                
Overview
                
Blood is made up of many parts, including red blood cells, white blood cells, platelets (PLATE-lets), and plasma (the fluid portion of blood).
                
Red blood cells are disc-shaped and look like doughnuts without holes in the center. They carry oxygen and remove carbon dioxide (a waste product) from your body. These cells are made in the bone marrowa sponge-like tissue inside the bones.
                
White blood cells and platelets (PLATE-lets) also are made in the bone marrow. White blood cells help fight infection. Platelets stick together to seal small cuts or breaks on the blood vessel walls and stop bleeding. With some types of anemia, you may have low numbers of all three types of blood cells.
                
Anemia has three main causes: blood loss, lack of red blood cell production, or high rates of red blood cell destruction. These causes might be the result of diseases, conditions, or other factors.
                
Outlook
                
Many types of anemia can be mild, short term, and easily treated. You can even prevent some types with a healthy diet. Other types can be treated with dietary supplements.
                
However, certain types of anemia can be severe, long lasting, and even life threatening if not diagnosed and treated.
                
If you have signs or symptoms of anemia, see your doctor to find out whether you have the condition. Treatment will depend on the cause of the anemia and how severe it is. + NHLBI + Anemia
