Women's Health

Women have unique health issues. And some of the health issues that affect both men and women can affect women differently.

Unique issues include pregnancy, menopause, and conditions of the female organs. Women can have a healthy pregnancy by getting early and regular prenatal care. They should also get recommended breast cancer, cervical cancer, and bone density screenings.

Women and men also have many of the same health problems. But these problems can affect women differently. For example:

• Women are more likely to die following a heart attack than men
• Women are more likely to show signs of depression and anxiety than men
• The effects of sexually transmitted infections (STIs) can be more serious in women
• Osteoarthritis affects more women than men
• Women are more likely to have urinary tract problems

Acute Flaccid Myelitis

What is acute flaccid myelitis (AFM)?

Acute flaccid myelitis (AFM) is a neurologic disease. It is rare, but serious. It affects an area of the spinal cord called gray matter. This can cause the muscles and reflexes in the body to become weak.

Because of these symptoms, some people call AFM a "polio-like" illness. But it is different from polio. AFM is not caused by polioviruses.

AFM can be caused by several different viruses. Researchers think that enteroviruses have been causing the recent increases in the number of children with AFM. AFM can also be caused by other viruses, including flaviviruses, herpesviruses, and adenoviruses.

Most people with AFM had a mild respiratory illness or fever (like you would get from a viral infection) before they got AFM.

Anyone can get AFM, but most cases (more than 90%) have been in young children.

Most people with AFM will suddenly have:

• Arm or leg weakness
• A loss of muscle tone and reflexes

Some people also have other symptoms, including:

• Facial drooping/weakness
• Trouble moving the eyes
• Drooping eyelids
• Trouble swallowing
• Slurred speech
• Pain in the arms, legs, back, or neck

Sometimes AFM can weaken the muscles that you need for breathing. This can lead to respiratory failure, which is very serious. If you get respiratory failure, you may need to use a ventilator (breathing machine) to help you breathe.

If you or your child develops any of these symptoms, get medical care right away.

AFM causes many of the same symptoms as other neurologic diseases, such as transverse myelitis and Guillain-Barre syndrome. This can make it difficult to diagnose. To find out if you have AFM, your doctor may use:

• A neurologic exam, including looking at where there is weakness, poor muscle tone, and decreased reflexes
• An MRI to look at the spinal cord and brain
• Lab tests on the cerebrospinal fluid (the fluid around the brain and spinal cord)
• Nerve conduction and electromyography (EMG) studies. These tests check nerve speed and the response of muscles to the messages from the nerves.

It is important that the tests are done as soon as possible after the symptoms start.

There is no specific treatment for AFM. A doctor who specializes in treating brain and spinal cord illnesses (neurologist) may recommend treatments for specific symptoms. For example, physical and/or occupational therapy may help with arm or leg weakness. Researchers do not know the long-term outcomes of people who get AFM.

There is no specific way to prevent AFM. But you can take steps to prevent getting sick from a virus by:

• Washing your hands often with soap and water
• Avoiding touching your face with unwashed hands
• Avoiding close contact with people who are sick
• Cleaning and disinfecting surfaces that you frequently touch, including toys
• Covering coughs and sneezes with a tissue or upper shirt sleeve, not hands
• Staying home when sick

Arrhythmia

What is an arrhythmia?

An arrhythmia is a problem with the rate or rhythm of your heartbeat. Your heart beats too quickly, too slowly, or with an irregular pattern. Changes in the electrical signals that control your heartbeat cause arrhythmias.

• When your heart beats faster than normal, it's called tachycardia.
• When your heart beats too slowly, it's called bradycardia.
• When the signal to beat comes too early, it's called a premature or extra heartbeat. It may feel like your heart skipped a beat.

There are many types of arrhythmias. Arrhythmias may affect the upper or lower chamber of your heart. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heartbeat.

Some arrhythmias are harmless, such as when your heart rate speeds up during exercise and slows down when you sleep. But if you have a frequent irregular rhythm, it may mean your heart isn't pumping enough blood into your body. Getting treatment and following a heart-healthy lifestyle can help control arrhythmias. It may also help prevent heart damage that can trigger some heart arrhythmias.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Other factors that could increase your risk for some types of arrhythmias could include if you:

• Have a family history of arrhythmias.
• Have certain health conditions, which can include heart and blood vessel diseases, lung diseases, kidney diseases, obesity, and sleep apnea.
• Are an older adult.
• Have had recent surgery for your heart, lungs, or throat.
• Take certain medicines for other health conditions.
• Use illegal drugs.

If you have risk factors, some situations that make your heart work harder, raise your blood pressure, or cause strong emotional stress may trigger an arrhythmia.

You may not have any noticeable symptoms of an arrhythmia. Your provider may find an arrhythmia during your routine checkup. Symptoms of an arrhythmia can include:

• Fast or slow heartbeat
• Skipping, fluttering, or pounding heartbeats
• Chest pain or discomfort
• Dizziness or fainting
• Shortness of breath
• Sweating
• Tiredness or weakness

Seek emergency medical care if you have chest pain, shortness of breath, or think you are having a heart attack.

To find out if you have an arrhythmia, your health care provider may order an electrocardiogram (EKG). This test records your heart's electrical activity and is the most common for finding an arrhythmia. Your provider may also:

• Ask about your medical history, including your symptoms and lifestyle habits.
• Do a physical exam, which includes checking your heartbeat and pulse.
• Order blood tests and other heart tests.
• Check your legs or feet for swelling.
• Look for signs of other health conditions that could cause an arrythmia, such as thyroid disease.

Treatment may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery. Your provider may also recommend avoiding activities that may trigger your arrhythmia.

The goal of treatment is to restore a normal heart rhythm. If not treated, arrhythmias can damage your heart, brain, and other organs and could be life-threatening.

To help prevent an arrhythmia, your provider may suggest that you make heart-healthy lifestyle changes and treat health conditions that may cause arrhythmias.

Autoimmune Diseases

What are autoimmune diseases?

Your immune system protects you from disease and infection by attacking germs that get into your body, such as viruses and bacteria. Your immune system can tell that the germs aren't part of you, so it destroys them. If you have an autoimmune disease, your immune system attacks the healthy cells of your organs and tissues by mistake.

There are more than 80 types of autoimmune diseases. They can affect almost any part of your body. For example, alopecia areata is an autoimmune disease of the skin that causes hair loss. Autoimmune hepatitis affects the liver. In type 1 diabetes, the immune system attacks the pancreas. And in rheumatoid arthritis, the immune system can attack many parts of the body, including the joints, lungs, and eyes.

No one is sure why autoimmune diseases happen. But you can't catch them from other people.

Autoimmune diseases do tend to run in families, which means that certain genes may make some people more likely to develop a problem. Viruses, certain chemicals, and other things in the environment may trigger an autoimmune disease if you already have the genes for it.

Millions of Americans of all ages have autoimmune diseases. Women develop many types of autoimmune diseases much more often than men. And if you have one autoimmune disease, you are more likely to get another.

The symptoms of an autoimmune disease depend on the part of your body that's affected. Many types of autoimmune diseases cause redness, swelling, heat, and pain, which are the signs and symptoms of inflammation. But other illnesses can cause the same symptoms.

The symptoms of autoimmune diseases can come and go. During a flare-up, your symptoms may get severe for a while. Later on, you may have a remission, which means that your symptoms get better or disappear for a period of time.

Doctors often have a hard time diagnosing autoimmune diseases. There's usually not a specific test to show whether you have a certain autoimmune disease. And the symptoms can be confusing. That's because many autoimmune diseases have similar symptoms. And some symptoms, such as muscle aches, are common in many other illnesses. So it can take a long time and some visits to different types of doctors to get a diagnosis.

To help your doctor find out if an autoimmune disease is causing your symptoms,:

• Learn about the health conditions in your family history. What health problems did your grandparents, aunts, uncles, and cousins have? Write down what you learn and share it with your doctor.
• Keep track of your symptoms, including how long they last and what makes them better or worse. Share your notes with your doctor.
• See a specialist who deals with the symptoms that bother you most. For example, if you have rash, see a dermatologist (skin doctor).

The treatment depends on the disease. In most cases, the goal of treatment is to suppress (slow down) your immune system, and ease swelling, redness, and pain from inflammation. Your doctor may give you corticosteroids or other medicines to help you feel better. For some diseases, you may need treatment for the rest of your life.
