Eyelid Disorders

Your eyelids help protect your eyes. When you blink, your eyelids spread moisture over your eyes. Blinking also helps move dirt or other particles off the surface of the eye. You close your eyelids when you see something coming toward your eyes. This can help protect against injuries.

Like most other parts of your body, your eyelids can get infected, inflamed, or even develop cancer. There are also specific eyelid problems, including:

Treatment of eyelid problems depends on the cause.

Pelvic Floor Disorders

The pelvic floor is a group of muscles and other tissues that form a sling or hammock across the pelvis. In women, it holds the uterus, bladder, bowel, and other pelvic organs in place so that they can work properly. The pelvic floor can become weak or be injured. The main causes are pregnancy and childbirth. Other causes include being overweight, radiation treatment, surgery, and getting older.

Common symptoms include:

Your health care provider diagnoses the problem with a physical exam, a pelvic exam, or special tests. Treatments include special pelvic muscle exercises called Kegel exercises. A mechanical support device called a pessary helps some women. Surgery and medicines are other treatments.

Mitral Valve Prolapse

What is the mitral valve?

The mitral valve is one of the four valves in your heart. Heart valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartbeats they close to stop the blood from flowing backwards.

The mitral valve opens to let blood flow from your heart's upper left chamber to the lower left chamber. When the lower left chamber contracts (squeezes) to pump blood to your body, the mitral valve closes tightly to keep any blood from flowing backwards.

What is mitral valve prolapse (MVP)?

Mitral valve prolapse (MVP) happens when the flaps of the mitral valve become floppy and don't close tightly. In some cases, blood may leak backwards through the valve to the chamber it came from. This is called backflow, or regurgitation. When there is a lot of mitral valve backflow, the heart can't push enough blood out to the body.

But most people who have MVP don't have any backflow. In fact, MVP doesn't cause any health problems for most people who have it.

Who is more likely to develop mitral valve prolapse (MVP)?

Anyone can have MVP. Most people who have it were born with it. MVP tends to run in families, but researchers don't know the exact cause.

You may be more likely to develop MVP if you:

Mitral valve prolapse with backflow is most common in men and people who have high blood pressure.

What are the symptoms of mitral valve prolapse (MVP)?

Most people who have MVP don't have any symptoms. But if it does cause symptoms, they may include:

What other problems can mitral valve prolapse (MVP) cause?

In rare cases, MVP can cause other problems. They're most often caused by backflow. They can include:

How is mitral valve prolapse (MVP) diagnosed?

Health care providers often find MVP during routine health check-ups. If you have MVP, your provider may hear a clicking sound when listening to your heart with a stethoscope. If blood flows backwards through the valve, your heart may also make a whooshing sound called a heart murmur.

You may also need certain heart tests. The most useful test is an echocardiogram, or echo. This is a type of ultrasound that uses sound waves to make a moving picture of your heart.

What are the treatments for mitral valve prolapse (MVP)?

Most people don't need any treatment for MVP. If you have symptoms with little or no backflow, you may only need medicine to relieve your discomfort.

If the amount of backflow is significant, you may need treatment to prevent other heart problems from developing. Treatments may include:

When possible, valve repair is generally preferred over replacement. That's because repairs are less likely to weaken the heart muscle, and they're less likely to cause heart infection.

Can mitral valve prolapse be prevented?

You can't prevent mitral valve prolapse. But if you have mitral valve prolapse, you can help prevent the rare but serious problems it can cause by:

Rectal Disorders

The rectum is the lower part of your large intestine where your body stores stool. Problems with rectum are common. They include hemorrhoids, abscesses, incontinence and cancer.

Many people are embarrassed to talk about rectal troubles. But seeing your doctor about problems in this area is important. This is especially true if you have pain or bleeding. Treatments vary depending on the particular problem.

Heart Valve Diseases

What are heart valve diseases?

Heart valve disease happens when one or more of your heart valves don't work well.

Your heart has four valves: the tricuspid, pulmonary, mitral, and aortic valves. The valves have flaps that open and close. The flaps make sure that blood flows in the right direction through your heart and to the rest of your body. When your heart beats, the flaps open to let blood through. Between heartbeats they close to stop the blood from flowing backwards.

If one or more of your heart valves doesn't open or close correctly, it can affect your blood flow and strain your heart. Fortunately, treatment helps most valve diseases.

What are the types of heart valve diseases?

Heart valves can have three basic kinds of problems:

Sometimes a valve can have both regurgitation and stenosis.

What causes heart valve diseases?

Some people are born with heart valve disease. This is called congenital heart valve disease. It can happen alone or along with other congenital heart defects. Heart valve disease can also develop over time as you get older or have certain conditions that affect the heart.

Who is more likely to develop heart valve diseases?

Your chance of having heart valve disease is higher if:

What are the symptoms of heart valve diseases?

Many people live their whole lives with a heart valve that doesn't work perfectly and never have any problems. But heart valve disease may get worse slowly over time. You may develop signs and symptoms, such as:

If you don't get treatment for heart valve disease, the symptoms and strain on your heart may keep getting worse.

What other problems can heart valve diseases cause?

When the valves don't work well, your heart has to pump harder to get enough blood out to the body. Without treatment, this extra workload on your heart can lead to:

How is heart valve disease diagnosed?

Your health care provider may listen to your heart with a stethoscope and hear that your heart makes abnormal sounds, such as a click or a heart murmur. These sounds may mean a valve isn't working normally. The provider will usually refer you to a cardiologist, a doctor who specializes in heart diseases.

The doctor will also listen to your heart and will do a physical exam. You will also likely need to have one or more heart tests.

What are the treatments for heart valve diseases?

Most heart valve problems can be treated successfully. Treatment may include:

It's possible that you may need surgery, even if you don't have symptoms. Fixing the valve can help can prevent future heart problems.

There are many ways to do heart valve surgery. You and your doctor can decide what's best for you, based on your valve problem and general health. Heart valve repair surgery has fewer risks than heart valve replacement. So, when repair is possible, it's preferred over valve replacement.

In some cases, valve replacement is necessary. There are 2 types of replacement valves:

Constipation

Constipation means that a person has three or fewer bowel movements in a week. The stool can be hard and dry. Sometimes it is painful to pass. At one time or another, almost everyone gets constipated. In most cases, it lasts a short time and is not serious.

There are many things you can do to prevent constipation. They include

It's not important that you have a bowel movement every day. If your bowel habits change, however, check with your doctor.

Endocarditis

What is endocarditis?

Endocarditis is sometimes called infective endocarditis. It's a rare, but life-threatening inflammation of the lining inside your heart's chambers and valves (the endocardium).

Endocarditis is usually caused by germs that get into your bloodstream and travel to your heart. Once they get inside your heart, the germs can attach to the lining or get trapped in the valves. They start to grow, causing an infection. If not treated quickly, the infection can cause damage to the heart and lead to serious health problems.

What causes endocarditis?

Bacterial infections cause most endocarditis. Normally, many bacteria live in your mouth, on your skin, or in other parts of the body. Sometimes the bacteria can get into your bloodstream from injuries such cuts or scrapes. Dental work and certain surgeries can also allow small amounts of bacteria to enter your bloodstream.

In some cases, fungal infections cause endocarditis. The fungi, such as yeast, can live in parts of your body. Fungal infections generally happen in people who have weakened immune systems that can't stop the fungus from growing. This includes people who have HIV.

Who is more likely to develop endocarditis?

In general, endocarditis is rare. If you're healthy, your immune system usually destroys the germs in your bloodstream before they can cause harm.

But your chance of developing endocarditis may be higher than most people if you:

What are the symptoms of endocarditis?

Endocarditis symptoms may be severe or very mild. They may start suddenly or slowly. And they can vary from person to person. The possible symptoms of endocarditis include:

What other problems can endocarditis cause?

When the germs are in your heart, they can clump together with blood cells. These clumps can break off and travel through your bloodstream. They may block blood flow, spread infection, or damage your organs, including your brain, lungs, kidneys, and spleen.

Endocarditis may sometimes lead to sepsis, a medical emergency that happens when your body has an extreme response to the infection.

Endocarditis can also cause serious heart problems including:

How is endocarditis diagnosed?

To find out if you have endocarditis, your doctor will:

What are the treatments for endocarditis?

If you have endocarditis, it's important to get treatment quickly. Treatments may include:

Treatment may last weeks, and you may need tests to make sure it's working. Your doctor will also check you for problems that could develop from endocarditis, such as heart failure or an irregular heartbeat.

Can endocarditis be prevented?

If you have a higher chance of developing endocarditis than most people, you can reduce your risk if you:

People with the highest risk for bacterial endocarditis need antibiotics before dental visits or certain medical or surgical procedures. Ask your provider if you're part of the highest risk group. If so, let all your providers know about your risk.

Hemorrhoids

What are hemorrhoids?

Hemorrhoids are swollen, inflamed veins around your anus or the lower part of your rectum. There are two types:

What causes hemorrhoids?

Hemorrhoids happen when there is too much pressure on the veins around the anus. This can be caused by:

What are the symptoms of hemorrhoids?

The symptoms of hemorrhoids depend on which type you have:

With external hemorrhoids, you may have:

Too much straining, rubbing, or cleaning around your anus may make your symptoms worse. For many people, the symptoms of external hemorrhoids go away within a few days.

With internal hemorrhoids, you may have:

Internal hemorrhoids are usually not painful unless they are prolapsed. Prolapsed internal hemorrhoids may cause pain and discomfort.

How can I treat hemorrhoids at home?

You can most often treat your hemorrhoids at home by:

When do I need to see a health care provider for hemorrhoids?

You should see your health care provider if you:

How are hemorrhoids diagnosed?

To find out if you have hemorrhoids, your health care provider:

What are the treatments for hemorrhoids?

If at-home treatments for hemorrhoids don't help you, you may need a medical procedure. There are several different procedures that your provider can do in the office. These procedures use different techniques to cause scar tissue to form in the hemorrhoids. This cuts off the blood supply, which usually shrinks the hemorrhoids. In severe cases, you may need surgery.

Can hemorrhoids be prevented?

You can help prevent hemorrhoids by:

Hysterectomy

A hysterectomy is surgery to remove a woman's uterus or womb. The uterus is the place where a baby grows when a woman is pregnant. After a hysterectomy, you no longer have menstrual periods and can't become pregnant. Sometimes the surgery also removes the ovaries and fallopian tubes. If you have both ovaries taken out, you will enter menopause.

Your health care provider might recommend a hysterectomy if you have:
