user: What causes Coronary Microvascular Disease ?

assistant: The same risk factors that cause atherosclerosis may cause coronary microvascular disease. Atherosclerosis is a disease in which plaque builds up inside the arteries.
                
Risk factors for atherosclerosis include:
                
Diabetes. It is a disease in which the bodys blood sugar level is too high because the body doesnt make enough insulin or doesnt use its insulin properly.
                
Family history of early heart disease. Your risk of atherosclerosis increases if your father or a brother was diagnosed with heart disease before age 55, or if your mother or a sister was diagnosed with heart disease before age 65.
                
High blood pressure. Blood pressure is considered high if it stays at or above 140/90mmHg over time. If you have diabetes or chronic kidney disease, high blood pressure is defined as 130/80 mmHg or higher. (The mmHg is millimeters of mercurythe units used to measure blood pressure.)
                
Insulin resistance. This condition occurs if the body cant use its insulin properly. Insulin is a hormone that helps move blood sugar into cells where its used for energy. Overtime, insulin resistance can lead to diabetes.
                
Lack of physical activity. Physical inactivity can worsen some other risk factors for atherosclerosis, such as unhealthy blood cholesterol levels, high blood pressure, diabetes, and overweight or obesity.
                
Older age. As you age, your risk for atherosclerosis increases. The process of atherosclerosis begins in youth and typically progresses over many decades before disease develops.
                
Overweight and obesity. The terms overweight and obesity refer to body weight thats greater than what is considered healthy for a certain height.
                
Smoking. Smoking can damage and tighten blood vessels, lead to unhealthy cholesterol levels, and raise blood pressure. Smoking also doesnt allow enough oxygen to reach the bodys tissues.
                
Unhealthy blood cholesterol levels. This includes high LDL (bad) cholesterol and low HDL (good) cholesterol.
                
Unhealthy diet. An unhealthy diet can raise your risk for atherosclerosis. Foods that are high in saturated and trans fats, cholesterol, sodium (salt), and sugar can worsen other risk factors for atherosclerosis.
                
In women, coronary microvascular disease also may be linked to low estrogen levels occurring before or after menopause. Also, the disease may be linked to anemia or conditions that affect blood clotting. Anemia is thought to slow the growth of cells needed to repair damaged blood vessels.
                
Researchers continue to explore other possible causes of coronary microvascular disease.
user: Who is at risk for Coronary Microvascular Disease? ?

assistant: Coronary microvascular disease can affect both men and women. However, women may be at risk for coronary microvascular disease if they have lower than normal levels of estrogen at any point in their adult lives. (This refers to the estrogen that the ovaries produce, not the estrogen used in hormone therapy.) Low estrogen levels before menopause can raise younger womens risk for the disease. Causes of low estrogen levels in younger women can be mental stress or a problem with the function of theovaries.
                
The causes of coronary microvascular disease and atherosclerosis are also considered risk factors for the disease.
user: What are the symptoms of Coronary Microvascular Disease ?

assistant: The signs and symptoms of coronary microvascular disease (MVD) often differ from the signs and symptoms of traditional coronary heart disease (CHD).
                
Many women with coronary MVD have angina (an-JI-nuh or AN-juh-nuh). Angina is chest pain or discomfort that occurs when your heart muscle doesn't get enough oxygen-rich blood.
                
Angina may feel like pressure or squeezing in your chest. You also may feel it in your shoulders, arms, neck, jaw, or back. Angina pain may even feel like indigestion.
                
Angina also is a common symptom of CHD. However, the angina that occurs in coronary MVD may differ from the typical angina that occurs in CHD. In coronary MVD, the chest pain usually lasts longer than 10 minutes, and it can last longer than 30 minutes. Typical angina is more common in women older than 65.
                
Other signs and symptoms of coronary MVD are shortness of breath, sleep problems, fatigue (tiredness), and lack of energy.
                
Coronary MVD symptoms often are first noticed during routine daily activities (such as shopping, cooking, cleaning, and going to work) and times of mental stress. It's less likely that women will notice these symptoms during physical activity (such as jogging or walking fast).
                
This differs from CHD, in which symptoms often first appear while a person is being physically activesuch as while jogging, walking on a treadmill, or going up stairs.
user: What are the treatments for Coronary Microvascular Disease ?

assistant: Relieving pain is one of the main goals of treating coronary microvascular disease (MVD). Treatments also are used to control risk factors and other symptoms. Treatments may include medicines, such as:
                
ACE inhibitors and beta blockers to lower blood pressure and decrease the hearts workload
                
Aspirin to help prevent blood clots or control inflammation
                
Nitroglycerin to relax blood vessels, improve blood flow to the heart muscle, and treat chest pain
                
Statin medicines to control or lower your blood cholesterol.
                
Take all medicines regularly, as your doctor prescribes. Dont change the amount of your medicine or skip a dose unless your doctor tells you to.
                
If youre diagnosed with coronary MVD and also haveanemia, you may benefit from treatment for that condition. Anemia is thought to slow the growth of cells needed to repair damaged blood vessels.
                
If youre diagnosed with and treated for coronary MVD, you should get ongoing care from your doctor. Research is under way to find the best treatments for coronary MVD.
user: Who is at risk for Sleep Deprivation and Deficiency? ?

assistant: Sleep deficiency, which includes sleep deprivation, affects people of all ages, races, and ethnicities. Certain groups of people may be more likely to be sleep deficient. Examples include people who:
                
Have limited time available for sleep, such as caregivers or people working long hours or more than one job
                
Have schedules that conflict with their internal body clocks, such as shift workers, first responders, teens who have early school schedules, or people who must travel for work
                
Make lifestyle choices that prevent them from getting enough sleep, such as taking medicine to stay awake, abusing alcohol or drugs, or not leaving enough time for sleep
                
Have undiagnosed or untreated medical problems, such as stress, anxiety, or sleep disorders
                
Have medical conditions or take medicines that interfere with sleep
                
Certain medical conditions have been linked to sleep disorders. These conditions include heart failure, heart disease, obesity, diabetes, high blood pressure, stroke or transient ischemic attack (mini-stroke), depression, and attention-deficit hyperactivity disorder (ADHD).
                
If you have or have had one of these conditions, ask your doctor whether you might benefit from a sleep study.
                
A sleep study allows your doctor to measure how much and how well you sleep. It also helps show whether you have sleep problems and how severe they are. For more information, go to the Health Topics Sleep Studies article.
                
If you have a child who is overweight, talk with the doctor about your child's sleep habits.
user: What are the symptoms of Sleep Deprivation and Deficiency ?

assistant: Sleep deficiency can cause you to feel very tired during the day. You may not feel refreshed and alert when you wake up. Sleep deficiency also can interfere with work, school, driving, and social functioning.
                
How sleepy you feel during the day can help you figure out whether you're having symptoms of problem sleepiness. You might be sleep deficient if you often feel like you could doze off while:
                
Sitting and reading or watching TV
                
Sitting still in a public place, such as a movie theater, meeting, or classroom
                
Riding in a car for an hour without stopping
                
Sitting and talking to someone
                
Sitting quietly after lunch
                
Sitting in traffic for a few minutes
                
Sleep deficiency can cause problems with learning, focusing, and reacting. You may have trouble making decisions, solving problems, remembering things, controlling your emotions and behavior, and coping with change. You may take longer to finish tasks, have a slower reaction time, and make more mistakes.
                
The signs and symptoms of sleep deficiency may differ between children and adults. Children who are sleep deficient might be overly active and have problems paying attention. They also might misbehave, and their school performance can suffer.
                
Sleep-deficient children may feel angry and impulsive, have mood swings, feel sad or depressed, or lack motivation.
                
You may not notice how sleep deficiency affects your daily routine. A common myth is that people can learn to get by on little sleep with no negative effects. However, research shows that getting enough quality sleep at the right times is vital for mental health, physical health, quality of life, and safety.
                
To find out whether you're sleep deficient, try keeping a sleep diary for a couple of weeks. Write down how much you sleep each night, how alert and rested you feel in the morning, and how sleepy you feel during the day.
                
Compare the amount of time you sleep each day with the average amount of sleep recommended for your age group, as shown in the chart in "How Much Sleep Is Enough?" If you often feel very sleepy, and efforts to increase your sleep don't help, talk with your doctor.
                
You can find a sample sleep diary in the National Heart, Lung, and Blood Institute's "Your Guide to Healthy Sleep."
user: What is (are) Varicose Veins ?

assistant: Espaol
                
Varicose (VAR-i-kos) veins are swollen, twisted veins that you can see just under the surface of the skin. These veins usually occur in the legs, but they also can form in other parts of the body.
                
Varicose veins are a common condition. They usually cause few signs and symptoms. Sometimes varicose veins cause mild to moderate pain, blood clots, skin ulcers (sores), or other problems.
                
Overview
                
Veins are blood vessels that carry blood from your body's tissues to your heart. Your heart pumps the blood to your lungs to pick up oxygen. The oxygen-rich blood then is pumped to your body through blood vessels called arteries.
                
From your arteries, the blood flows through tiny blood vessels called capillaries, where it gives up its oxygen to the body's tissues. Your blood then returns to your heart through your veins to pick up more oxygen. For more information about blood flow, go to the Health Topics How the Heart Works article.
                
Veins have one-way valves that help keep blood flowing toward your heart. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell, which can lead to varicose veins.
                
Many factors can raise your risk for varicose veins. Examples of these factors include family history, older age, gender, pregnancy, overweight or obesity, lack of movement, and leg trauma.
                
Varicose veins are treated with lifestyle changes and medical procedures. The goals of treatment are to relieve symptoms, prevent complications, and improve appearance.
                
Outlook
                
Varicose veins usually don't cause medical problems. If they do, your doctor may simply suggest making lifestyle changes.
                
Sometimes varicose veins cause pain, blood clots, skin ulcers, or other problems. If this happens, your doctor may recommend one or more medical procedures. Some people choose to have these procedures to improve the way their veins look or to relieve pain.
                
Many treatments for varicose veins are quick and easy and don't require a long recovery.
user: What causes Varicose Veins ?

assistant: Weak or damaged valves in the veins can cause varicose veins. After your arteries and capillaries deliver oxygen-rich blood to your body, your veins return the blood to your heart. The veins in your legs must work against gravity to do this.
                
One-way valves inside the veins open to let blood flow through, and then they shut to keep blood from flowing backward. If the valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell.
                
Weak vein walls may cause weak valves. Normally, the walls of the veins are elastic (stretchy). If these walls become weak, they lose their normal elasticity. They become like an overstretched rubber band. This makes the walls of the veins longer and wider, and it causes the flaps of the valves to separate.
                
When the valve flaps separate, blood can flow backward through the valves. The backflow of blood fills the veins and stretches the walls even more. As a result, the veins get bigger, swell, and often twist as they try to squeeze into their normal space. These are varicose veins.
                
Normal Vein and Varicose Vein
                

                
Figure A shows a normal vein with a working valve and normal blood flow. Figure B shows a varicose vein with a deformed valve, abnormal blood flow, and thin, stretched walls. The middle image shows where varicose veins might appear in a leg.
                
Older age or a family history of varicose veins may raise your risk for weak vein walls. You also may be at higher risk if you have increased pressure in your veins due to overweight or obesity or pregnancy.
user: Who is at risk for Varicose Veins? ?

assistant: Many factors may raise your risk for varicose veins, including family history, older age, gender, pregnancy, overweight or obesity, lack of movement, and leg trauma.
                
Family History
                
Having family members who have varicose veins may raise your risk for the condition. About half of all people who have varicose veins have a family history of them.
                
Older Age
                
Getting older may raise your risk for varicose veins. The normal wear and tear of aging may cause the valves in your veins to weaken and not work well.
                
Gender
                
Women tend to get varicose veins more often than men. Hormonal changes that occur during puberty, pregnancy, and menopause (or with the use of birth control pills) may raise a woman's risk for varicose veins.
                
Pregnancy
                
During pregnancy, the growing fetus puts pressure on the veins in the mother's legs. Varicose veins that occur during pregnancy usually get better within 3 to 12 months of delivery.
                
Overweight or Obesity
                
Being overweight or obese can put extra pressure on your veins. This can lead to varicose veins. For more information about overweight and obesity, go to the Health Topics Overweight and Obesity article.
                
Lack of Movement
                
Standing or sitting for a long time, especially with your legs bent or crossed, may raise your risk for varicose veins. This is because staying in one position for a long time may force your veins to work harder to pump blood to your heart.
                
Leg Trauma
                
Previous blood clots or traumatic damage to the valves in your veins can weaken their ability to move blood back to the heart, increasing the risk for varicose veins.
user: What are the symptoms of Varicose Veins ?

assistant: The signs and symptoms of varicose veins include:
                
Large veins that you can see just under the surface of your skin.
                
Mild swelling of your ankles and feet.
                
Painful, achy, or "heavy" legs.
                
Throbbing or cramping in your legs.
                
Itchy legs, especially on the lower leg and ankle. Sometimes this symptom is incorrectly diagnosed as dry skin.
                
Discolored skin in the area around the varicose vein.
                
Signs of telangiectasias are clusters of red veins that you can see just under the surface of your skin. These clusters usually are found on the upper body, including the face. Signs of spider veins are red or blue veins in a web or tree branch pattern. Often, these veins appear on the legs and face.
                
See your doctor if you have these signs and symptoms. They also may be signs of other, more serious conditions.
                
Complications of Varicose Veins
                
Varicose veins can lead to dermatitis (der-ma-TI-tis), an itchy rash. If you have varicose veins in your legs, dermatitis may affect your lower leg or ankle. Dermatitis can cause bleeding or skin ulcers (sores) if the skin is scratched or irritated.
                
Varicose veins also can lead to a condition called superficial thrombophlebitis (THROM-bo-fleh-BI-tis). Thrombophlebitis is a blood clot in a vein. Superficial thrombophlebitis means that the blood clot occurs in a vein close to the surface of the skin. This type of blood clot may cause pain and other problems in the affected area.
user: How to diagnose Varicose Veins ?

assistant: Doctors often diagnose varicose veins based on a physical exam alone. Sometimes tests or procedures are used to find out the extent of the problem or to rule out other conditions.
                
Specialists Involved
                
If you have varicose veins, you may see a vascular medicine specialist or vascular surgeon. These doctors specialize in blood vessel conditions. You also may see a dermatologist. This type of doctor specializes in skin conditions.
                
Physical Exam
                
To check for varicose veins in your legs, your doctor will look at your legs while you're standing or sitting with your legs dangling. He or she may ask you about your signs and symptoms, including any pain you're having.
                
Diagnostic Tests and Procedures
                
Duplex Ultrasound
                
Your doctor may recommend duplex ultrasound to check blood flow in your veins and to look for blood clots. Duplex ultrasound combines traditional with Doppler ultrasound. Traditional ultrasound uses sound waves to create apicture of the structures in your body, in this case the blood vessels and anything that may be blocking the flow of blood. Doppler ultrasound uses sound waves to create pictures of the flow or movement of the blood through theveins. The two types of ultrasound together paint a picture that helps your doctor diagnose your condition.
                
During this test, a handheld device will be placed on your body and passed back and forth over the affected area. The device sends and receives sound waves. A computer will convert the sound waves into a picture of the blood flow in your arteries and veins.
                
Angiogram
                
Although it is not very common, your doctor may recommend an angiogram to get a more detailed look at the blood flow through your veins.
                
For this procedure, dye is injected into your veins. The dye outlines your veins on x-ray images.
                
An angiogram can help your doctor confirm whether you have varicose veins or another condition.
user: How to prevent Varicose Veins ?

assistant: You can't prevent varicose veins from forming. However, you can prevent the ones you have from getting worse. You also can take steps to delay other varicose veins from forming.
                
Avoid standing or sitting for long periods without taking a break. When sitting, avoid crossing your legs. Keep your legs raised when sitting, resting, or sleeping. When you can, raise your legs above the level of your heart.
                
Do physical activities to get your legs moving and improve muscle tone. This helps blood move through your veins.
                
If you're overweight or obese, try to lose weight. This will improve blood flow and ease the pressure on your veins.
                
Avoid wearing tight clothes, especially those that are tight around your waist, groin (upper thighs), and legs. Tight clothes can make varicose veins worse.
                
Avoid wearing high heels for long periods. Lower heeled shoes can help tone your calf muscles. Toned muscles help blood move through the veins.
                
Wear compression stockings if your doctor recommends them. These stockings create gentle pressure up the leg. This pressure keeps blood from pooling in the veins and decreases swelling in the legs.
user: What is (are) ARDS ?

assistant: ARDS, or acute respiratory distress syndrome, is a lung condition that leads to low oxygen levels in the blood. ARDS can be life threatening because your body's organs need oxygen-rich blood to work well.
                
People who develop ARDS often are very ill with another disease or have major injuries. They might already be in the hospital when they develop ARDS.
                
Overview
                
To understand ARDS, it helps to understand how the lungs work. When you breathe, air passes through your nose and mouth into your windpipe. The air then travels to your lungs' air sacs. These sacs are called alveoli (al-VEE-uhl-eye).
                
Small blood vessels called capillaries (KAP-ih-lare-ees) run through the walls of the air sacs. Oxygen passes from the air sacs into the capillaries and then into the bloodstream. Blood carries the oxygen to all parts of the body, including the body's organs.
                
In ARDS, infections, injuries, or other conditions cause fluid to build up in the air sacs. This prevents the lungs from filling with air and moving enough oxygen into the bloodstream.
                
As a result, the body's organs (such as the kidneys and brain) don't get the oxygen they need. Without oxygen, the organs may not work well or at all.
                
People who develop ARDS often are in the hospital for other serious health problems. Rarely, people who aren't hospitalized have health problems that lead to ARDS, such as severe pneumonia.
                
If you have trouble breathing, call your doctor right away. If you have severe shortness of breath, call 911.
                
Outlook
                
More people are surviving ARDS now than in the past. One likely reason for this is that treatment and care for the condition have improved. Survival rates for ARDS vary depending on age, the underlying cause of ARDS, associated illnesses, and other factors.
                
Some people who survive recover completely. Others may have lasting damage to their lungs and other health problems.
                
Researchers continue to look for new and better ways to treat ARDS.
user: What causes ARDS ?

assistant: Many conditions or factors can directly or indirectly injure the lungs and lead to ARDS. Some common ones are:
                
Sepsis. This is a condition in which bacteria infect the bloodstream.
                
Pneumonia. This is an infection in the lungs.
                
Severe bleeding caused by an injury to the body.
                
An injury to the chest or head, like a severe blow.
                
Breathing in harmful fumes or smoke.
                
Inhaling vomited stomach contents from the mouth.
                
It's not clear why some very sick or seriously injured people develop ARDS and others don't. Researchers are trying to find out why ARDS develops and how to prevent it.
