A kidney transplant is an operation that places a healthy kidney in your body. The transplanted kidney takes over the work of the two kidneys that failed, so you no longer need dialysis.
During a transplant, the surgeon places the new kidney in your lower abdomen and connects the artery and vein of the new kidney to your artery and vein. Often, the new kidney will start making urine as soon as your blood starts flowing through it. But sometimes it takes a few weeks to start working.
Many transplanted kidneys come from donors who have died. Some come from a living family member. The wait for a new kidney can be long.
If you have a transplant, you must take drugs for the rest of your life, to keep your body from rejecting the new kidney.

Laboratory tests check a sample of your blood, urine, or body tissues. A technician or your doctor analyzes the test samples to see if your results fall within the normal range. The tests use a range because what is normal differs from person to person. Many factors affect test results. These include:
Your doctor may also compare your results to results from previous tests. Laboratory tests are often part of a routine checkup to look for changes in your health. They also help doctors diagnose medical conditions, plan or evaluate treatments, and monitor diseases.
You've probably heard that high blood pressure is a problem. Sometimes blood pressure that is too low can also cause problems.
Blood pressure is the force of your blood pushing against the walls of your arteries. Each time your heart beats, it pumps out blood into the arteries. Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is the diastolic pressure. Your blood pressure reading uses these two numbers. Usually they're written one above or before the other, such as 120/80. If your blood pressure reading is 90/60 or lower, you have low blood pressure.
Some people have low blood pressure all the time. They have no symptoms and their low readings are normal for them. In other people, blood pressure drops below normal because of a medical condition or certain medicines. Some people may have symptoms of low blood pressure when standing up too quickly. Low blood pressure is a problem only if it causes dizziness, fainting or in extreme cases, shock.

What is Lyme disease?
Lyme disease is a bacterial infection you get from the bite of an infected tick. At first, Lyme disease usually causes symptoms such as a rash, fever, headache, and fatigue. But if it is not treated early, the infection can spread to your joints, heart, and nervous system. Prompt treatment can help you recover quickly.What causes Lyme disease?
Lyme disease is caused by bacteria. In the United States, this is usually a bacterium called Borrelia burgdorferi. It spreads to humans through the bite of an infected tick. The ticks that spread it are blacklegged ticks (or deer ticks). They are usually found in the:
These ticks can attach to any part your body. But they are often found in hard-to-see areas such as your groin, armpits, and scalp. Usually the tick must be attached to you for 36 to 48 hours or more to spread the bacterium to you.Who is at risk for Lyme disease?
Anyone can get a tick bite. But people who spend lots of time outdoors in wooded, grassy areas are at a higher risk. This includes campers, hikers, and people who work in gardens and parks.
Most tick bites happen in the summer months when ticks are most active and people spend more time outdoors. But you can get bitten in the warmer months of early fall, or even late winter if temperatures are unusually high. And if there is a mild winter, ticks may come out earlier than usual.What are the symptoms of Lyme disease?
Early symptoms of Lyme disease start between 3 to 30 days after an infected tick bites you. The symptoms can include:
If the infection is not treated, it can spread to your joints, heart, and nervous system. The symptoms may include:
To make a diagnosis, your health care provider will consider:
Most Lyme disease tests check for antibodies made by the body in response to infection. These antibodies can take several weeks to develop. If you are tested right away, it may not show that you have Lyme disease, even if you have it. So you may need to have another test later.What are the treatments for Lyme disease?
Lyme disease is treated with antibiotics. The earlier you are treated, the better; it gives you the best chance of fully recovering quickly.
After treatment, some patients may still have pain, fatigue, or difficulty thinking that lasts more than 6 months. This is called post-treatment Lyme disease syndrome (PTLDS). Researchers don't know why some people have PTLDS. There is no proven treatment for PTLDS; long-term antibiotics have not been shown to help. However, there are ways to help with the symptoms of PTLDS. If you have been treated for Lyme disease and still feel unwell, contact your health care provider about how to manage your symptoms. Most people do get better with time. But it can take several months before you feel all better.Can Lyme disease be prevented?
To prevent Lyme disease, you should lower your risk of getting a tick bite:

Meniere's disease is a disorder of the inner ear. It can cause severe dizziness, a roaring sound in your ears called tinnitus, hearing loss that comes and goes and the feeling of ear pressure or pain. It usually affects just one ear. It is a common cause of hearing loss.
Attacks of dizziness may come on suddenly or after a short period of tinnitus or muffled hearing. Some people have single attacks of dizziness once in a while. Others may have many attacks close together over several days. Some people with Meniere's disease have "drop attacks" during which the dizziness is so bad they lose their balance and fall.
Scientists don't yet know the cause. They think that it has to do with the fluid levels or the mixing of fluids in the canals of your inner ear. Doctors diagnose it based on a physical exam and your symptoms. A hearing test can check to see how it has affected your hearing.
There is no cure. Treatments include medicines to control dizziness, limiting salt in your diet, and taking water pills. A device that fits into the outer ear and delivers air pulses to the middle ear can help. Severe cases may require surgery.
